Jet Database Engine 3.x errors

A Jet Database Engine serves as the underlying component of a database and all the information is stored on it in the networked scenario. Any wrong thing happened to it, can lead to the corruption of database and in most of the cases where data corrupted is of much importance, needs to be repaired. When some of the corruption happens in the database of Microsoft Jet database engine 3.x, following are the most common error messages returned:

“The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.”

This error message is displayed when the long value column has bad data stored
in it. The page in which the row is stored differs from the one in which the long value is stored. But if it is stored in the table schema, then a pointer is used in the data row to read the data in it and the problem encounters when the row pointer is unable to read properly the data in the long value page.

Another error message which occurs when the Jet Database Engine improperly shuts down while the process of writing down to the disk was going on displays:

“Unrecognized database format ‘databasename.mdb’.”

Also due to misplacement of an index on the MSysObjects table, an error message is encountered that announces:

“’databasename.mdb’ isn’t an index in this table. Look in the Indexes collection of the TableDef object to determine the valid index names.”

This problem is particularly caused when the repair procedure is aborted.

Well the reasons can be many which indicate that the database is corrupted and requires a repair but Microsoft has suggested one common solution to all of them.
The Microsoft Jet database engine version 3.51 possesses a compact process to solve out the problem. This has been designed for Microsoft Access 97, so it requires that this file version is installed on your computer system, which may some times not be possible. Moreover the tool is not so powerful to repair the damaged databases due to some external reasons like simultaneous access to the database.

In these circumstances, you require to go for certain another options which could repair your databases. The most commonly used one is termed as Access Repair software. The software can repair the Access databases with the original content and view as they are read only applications.

Stellar provides the best Access repair software called Stellar Phoenix Access Recovery software. This application is well-suited for all the file versions of Access including Access 97, 2000, 2002/ XP, 2003 and 2007.
There is a variety of features of this software which ensures repairing the software with much competence like it can repair the databases which contains relations between tables and the table which contains Query, Form, Report, Macro and Modules. The software is easy to use and its demo version is available at the website which helps you to preview all the repairable files.

 

Record Is Deleted Error Message in MS Access

When you try to open a table, query, form, report or a data access page you may get the following error message:
“Record is deleted.”
In the case of a table or a query the error message displayed may be in the form:
“Msaccess can’t open the table in datasheet view.”
While if you are dealing with a report the error message may take the following form:
“Unable to carry out the command.
There was an error executing the command.”

This behavior is shown by the MS Access in the multi user environment when the database is stored on the network. When the LAN is spread in a building or a more wide area, then it is a common practice adopted by the users to save anAccess database on the network so that it can be accessed by them. These databases usually contain some important company or organization related information which can not be lost at any price. So it is required that no data loss may happen and the data will remain safe.

The above mentioned error messages occur if either the object or whole of the database is damaged. The problem arises when the same record in the database is being modified by two or more users simultaneously and in the mean time if any of the user forces the Access to close by shutting down his/her computer system.

To solve this problem Microsoft has suggested repairing the database using Compact and Repair utility tool. But there is a downslide to it that the database which has undergone a mild damage can be repaired by this tool but those which are highly damaged can’t be repaired using this tool, so at last your database may remain damaged or corrupted.

In this case the only option left to repair the database is to imply theAccess Repair software. These software are read only software that without changing the original content of the database, are able to repair the database with much efficiency.

Stellar Phoenix Access Recovery software has marked a tremendous performance in repairing the Access databases irrespective of the amount of damage occurred to the database. The software is found to be compatible with all the file versions of MS Access including Access 2000, 2002, 2003 and 2007. If the databases contain a number of queries, forms, reports, or tables the software is able to repair all of them.
It possesses an advanced scanning feature in order to locate all the damaged files. The user needs not to be technically savvy to operate the software.
So if you have any doubt about the performance of the software, the demo version
is available to check out which of your mdb files are repairable.

 

Table Corruption after Referential Integrity Checks

MS Access is used to create relational databases and in these databases, integrity constraints are widely enforced in order to develop consistency between coupled tables usually by a combination of primary key or candidate key and a foreign key.
When you try to add records from one database table to another one by using an append query, you may face the following error message in MS Access:
“Microsoft Access can’t append all the records in the append query.

Microsoft Access set 0 field(s) to Null due to a type conversion failure, and it didn’t add <number> record(s) to the table due to key violations, 0 record(s) due to lock violations, and 0 record(s) due to validation rule violations.

Do you want to run the action query anyway?
To ignore the error(s) and run the query, click Yes.
For an explanation of the causes of the violations, click Help.”

Or when you try to export the table, the following error message may be encountered:

“The Microsoft Jet Database Engine could not find the Object ". Make sure the object exists and that you spelled its name correctly.”

When you click ‘ok’, another error message displays:

“An error occurred trying to export the data from table ‘tablename’. The data was not exported.”

These are the error messages which get displayed when the table you are handling
has a self join and memo fields and has a referential integrity enforced or the table is corrupted. The Access database corruption may give rise to problems of data loss as these databases provide a wide source of information and loosing any one of them could be a big disaster.

Memo fields are used to store large amount of data, so the databases which is having a referential integrity and self join adds memo fields to itself. So Microsoft has suggested to change them either to text fields or to move them to a separate table.

The key suggested requires a deep knowledge of user interface on single user computers, so handling the above solution becomes a tough task for some and the table may remain in as it is state. So it is required to get a solution which could repair their databases in either of the way.

Access repair software are the way to it which repair your databases irrespective of the reason and hence help you to get data which was there in your databases. These software serve as effective tool for repairing the access databases.

Stellar Phoenix Access Recovery software is the most secure and the easiest to use application which has specially been designed to work for all the file versions of access including Access 97/ 2000, 2002, XP, 2003 and 2007. MDB file corruption is a big headache for some, so this software has been designed by developers keeping this point in mind and thus provides the best solution. This software can recover all the relations between the tables and also all the keys if present in the table. No prior technical knowledge is bagged by this software if you want to operate it.

Resolving Error Message: ActiveX Component Can’t Create Object

While using Microsoft Access you may get the following error message flashing on your computer screen:

“ActiveX component can’t create object”

There can be any cause which resulted in this error message like a damaged wizard file or loss of more than one references or not a proper registration of DAO (Data Access Objects) or an invalid utility database reference or not having required permissions for libraries.

Before going for any solution one should have an idea what the problem is as the solution runs respectively with the root of the problem and if you are unable to judge the cause of the problem then the loss is all yours in the form of data. And if you know the reason then Microsoft has suggested the few of the solution which depends upon the root cause:

1. If this is due to wizard file damage then search for those file and change each file extension from .mde to .old. To restore these files reinstallation of the MS Access application is required.
2. For missing reference reason first you need to search for those files which are found to be marked missing and then re-associate the reference.
3. For registering the files which have not been, run regsvr32 file along with the required file name
4. If the problem is invalid utility database reference then clear all the check boxes next to any reference to Utility Database or Utility.mda.

So the conclusion is that you should know the reason first and somehow if you are able to do so then next problem is that you are not able to follow the solution steps as this require a wide knowledge. But there is no other way which could replace your data, so at last you come with the judgment that better you should reinstall the application. Also in case of wizard file damage you require to do so.

Reinstalling the application is never becomes a problem even to a less knowledge based user but be ready to face certain other upcoming problems with this process i.e. database corruption. Your mdb files may get corrupted during this process and you may suffer data loss.

Recovering from this condition becomes a ‘do or die’ issue in few of the cases where certain of your important data lie there on these files. The solution for this problem is there and you can follow it simply.Access repair software will help you to recover from the same drastic condition. There is a crowd of Access Repair software in market and searching for the best one can be another issue.

Stellar Phoenix Access Recovery software is the end of your search. This software gives you a 100% assurance of mdb file repair and is capable of repairing and restoring them with much efficiency. It provides an easy to use and simple to operate interface to work with. By following powerful algorithms, this software helps you to repair Access files in each file version including Access 97, 2000, 2002, 2003 and 2007. It can repair those file also which include reports, relations between tables and primary key fields. If you are not sure about its skill then you can go for a preview of the repairable files with its demo version.

 

Couldn’t Find File WIZARD.MDA - Error Message

This may happen when you try to open an access database you encounter the following message:
"Couldn’t Find File WIZARD.MDA”
And
“Some libraries or modules could not load. Click OK or press ENTER to continue”

Our Windows directory contains a file named ‘MSACC20.INI’ and if this file gets deleted, renamed or moved then this problem may arise. This file accounts for the ODBC settings and is created by Microsoft Access setup. This is a text file such as notepad. So any damage or change in this file creates a problem. Even after a change or corruption in this file the MS Access version 1.x MSACCESS.INI file is still there in the directory. So if the file is not accessed by Microsoft Access version 2.0 then it uses the 1.x MSACCESS.INI file.

Microsoft has suggested that to resolve this problem you need to search for the file and rename it and if it has been deleted then you need to recreate it. Renaming the file again doesn’t become an issue for anyone and requires simple steps like searching for it and then renaming it in file manager. But the main problem comes when you need to recreate it as recreating the file requires the reinstallation of MS Access application.

Reinstallation of MS Access may definitely solve the problem but simultaneously certain other issues like corruption of existing databases may arise and it could lead to a big problem as those databases may possess certain useful information which if get corrupted or damaged by some reason could take you and your company at the end. MS Access is a frequently used tool and mdb files contain those data which is very beneficial for any organization in terms of economy and development. So there should be some tools kept in mind which could help you to recover from this kind of data loss condition.

The one and the only solution which is there to help you out so that your mdb files can be repaired and restored isaccess repair software. These software are application specific software which repair your databases in each and every case of damage.

Stellar Phoenix Access Recovery software is the most advanced software serving the same purpose. This software has specially been designed to work with all the file versions of MS Access including Access 97, 2000, 2002, 2003 and 2007. It performs a complete scan of the corrupted mdb files and then repairs and restores with much efficiency. If your file is having relations, images, primary key fields etc., then there is no need to bother as this software will help you to repair all of them.
 

Concurrent Appends to a Memo Field Can Cause Corruption and Produces the #deleted Symbol

Memo fields are used by user when there is a need of saving large amount of text in the database. They can store up to 1 gigabyte of characters of which 65,535 characters can be displayed and you can also do rich-text formatting to the data in a Memo field like you can set colors to the text.

But when the database is over the network then the concurrent appending to the memo fields can lead to corruption of data. You can do only one concurrent append to a file on multiple workstations at a time. Once the data is corrupted in these mdb files then the field displays a #deleted symbol. Further access to the same database will generate the following error:
“The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time”.

When you try to repair the database with compact repair utility tool a wrong message is displayed that it has been repaired successfully but in reality it is not so as when you compact it further another message displays:

“Record(s) can’t be read; no read permission on ‘filename’.”

The reason behind this is that when multiple appending is done to any database they are not identified and hence the data gets corrupted.

To solve this problem Microsoft has suggested obtaining Jet35sp3.exe (Microsoft Jet 3.5 Service Pack 3) file. But sometimes it may happen that after obtaining this file too your database still remains in corrupted form. The corrupted data may create a big problem as these mob files may contain several relevant information’s.

To come up from this condition variousaccess repair software are available which are able to repair these mdb files and restore them. These software scan all your corrupted files and repair them.

Stellar Phoenix Access Recovery software is one of the leading software which provides this solution. This software is secure and easy to use and provides you an interactive interface to work upon. All the file versions of MS Access are supported by this software including Access 97, 2000, 2002/XP, 2003 and 2007. Its demo version provides you an overview of all the files which can be repaired and after using it you can store as per your suitability.
 

Mdb Files Corruption due to faulty Network Hardware

MS access possesses a wonderful feature of having the ability to share files over the network. As we are able to make relational databases through it, sharing these files on the network provides a good way to share information. There are various ways of sharing an mdb file on the network and it also involves certain components like Jet database engine and certain other network hardwares like network interface cards, network cables, routers and hubs which ultimately form a hardware chain.

When an mdb file corrupts most of the damage occurs due to Jet database engine failure but there are also many cases where the corruption occurs due to fault in some network hardware. In these cases the data fed to the faulty hardware is not processed correctly which ultimately leads to the corruption of database and hence data loss. This damage can either be mild or severe depending upon the amount of fault in the hardware. Apart from this, there can be other reasons too which can cause database corruption;
1. Slow or configured network software.
2. If you are running on Windows 95 or Windows 98, crashes in unrelated programs, drivers and utility software (such as screensavers) can be responsible.

Now if you are unaware of whether the fault happened in the hardware chain or not and if you are able to see the icon of the moved or copied file on your computer, then when you will open it you will get some error message and the file will not open. To be sure, that the file is corrupted only due to the reason of fault in network hardware, try to repair the file by compact and repair utility or jet comp and if this doesn’t solve the problem, then it is confirmed that the problem is certainly due to fault in hardware chain. The reason can be any of the following:
1. Cyclic redundancy check error
2. Unmatched parity bit error.

These problems continue the same way until the responsible hardware is detected and replaced. But the data which is already corrupted can be repaired by another way called access repair software which is operated on the destination system (where the corrupted file has been encountered) either server or client. These software can repair the corrupted databases and hence restore them.

Stellar provides one of the best software for this called Stellar Phoenix Access Recovery software. This software works for all file version of access including Access 97, 2000, 2003, 2007 and 2002. This software recovers all the data type included in the database and provides you an interactive interface to work upon.
The most important advantage is that to use it, this not necessary that you should have an extended technical knowledge.
 

Microsoft Access 2000: Troubleshooting Invalid Page Faults

Often when you try to open any saved ‘mdb’ files saved on your computer system or while you are working on a form which contains events or procedures you may face an invalid page fault and a message like:

“This application has performed an illegal operation and will be shut down.”
And when you go for the details you encounter another message stating:

“Msaccess.exe caused an invalid page fault in module VBA232.DLL.”

There are certain reasons for the same like if there is any bug in VBA development environment or mismatched .dll files or damage or corruption of database or incorrect registry settings.

Microsoft Access is a powerful tool which is used by users frequently and if any mishappening happens to the saved mdb files then it becomes very important to some of users to recover it as it may possess very important data .There are many solutions for the problem which depends upon the cause and can be adopted to overcome the above stated problem like:

1. As the error is due to fault in VBA232.dll file then reinstalling the most recent update to this dll file may solve the problem
2. If the error is due to damage or corruption of file then we should immediately run the Compact and Repair utility to correct any potential problems caused by damage to the structure or data of the current database.
3. If the problem is due to mismatching of dll files then you can follow the following steps: Search for the file listed in window explorer and rename it to a unique name. Then uninstall the MS Access and then again reinstall it.
4. Incorrect registry settings could be another cause for the same which can be corrected by first accessing MS Access in control panel and then clicking on the add/remove button which will display the corresponding maintenance window where after clicking on the repair office you can go for the reinstallation of Microsoft Office.

If the problem still persists or you encounter some other problem of data corruption then there is none other alternative of adopting aaccess repair software. These software provide a complete solution of repairing and restoring back your access files and hence no data oss.

Stellar Phoenix Access Recovery Software is the most advanced software which does the same work in this era. This software supports all the latest file versions of MS Access including Access 97, 2000, 2002, 2003 and 2007. This software first scans and then repairs and restores the corrupted files in the default location or any other specified location as mentioned by the user. Its demo version gives you the preview of repaired database.

Can’t Open a Form or Report in Access

When you open an existing MS Access database, you may get the following error message:

“Can’t open a form or report”.

After this error message, you can’t access the database.

This error message generally occurs due to possible corruption in Access Database while developing or modifying forms or reports and the code in their modules.

This error message may also occur when you try to open a database that’s Record Source property hasn’t defined.

To work around this problem, import your corrupted database in a new database. You can do it by following these steps:

1. Create a new database and import the corrupted database table along with all the elements like forms, reports, queries and macros in it.
2. Set the reference of the database.
3. Compile the database.

The issue will be resolved using this method if it has occurred due to Record Source problem. But in case if it has occurred due to database corruption, you won’t be able to change the database reference.

In these situations, you need to repair Access database. To repair your corrupted database, you need for Access repair or .mdb repair (MS Access database file) software. This software is capable to repair and restore the corrupted MS Access database. Access Repair software is read only and non destructive file recovery software that restores the file in its original format without modifying the original contents of it.

Stellar Phoenix Access Recovery is robust and powerful .mdb repair software that can help you in repairing and restoring your corrupted .mdb or Access Database files in almost all possible cases of corruption. Stellar Phoenix Access Recovery software uses advanced searching algorithms to search and locate the corrupted Access database and repair them. This software is capable to repair all the elements of Access database including forms, reports, tables, macros, queries and database relationships. This Access Repair software is compatible with all file versions of Microsoft Access including Access 97, 2000, 2002, 2003 and 2007.
 

Corruption in Shared Access Database and Recovery

Database sharing is the most useful and advanced feature of Microsoft Access. This feature has enabled since the Database engine is File based. In order to allow multiple users to share the same file over the network, Jet Database Engine uses a Lock file (.ldb) to synchronize the read write operations of the database.

Unluckily using the Lock file communicates on Windows operating system API calls to control the file synchronization which in turn communicate on file transfer networking protocols. All of the network connections have a bandwidth limit, and any software on your system transferring data on the same network socket can potentially decrease the jet connection speed, when it happens the connection generally disconnects due to the “Time-Out” failure. When it happens, the Access Database is left in a “Suspect” state and generally requires repairing it before allow it to continue.

Most of the times, the network problem leave the Access database in a “Suspect” state and cause corruption. It depends what the users were doing when the network problem occurred. For instance, if the user was performing any large SQL Append query, it is obvious that the database will corrupt. If you increase the network performance by disabling “opportunistic locking, it increase the chances of database corruption in a shared environment.

In all of these situations, you need to repair your Access database in order to use it. You can repair the corrupted database with the help of third party data recovery software that are known as Access Recovery software for repairing MS Access database files.

Access Repair is the application programs that can help you in repairing and restoring the corrupted Access Database in almost all possible cases of corruption. This software works on the header of the corrupted file and repairs and restores it without changing the original contents of the database files. This software is able to repair all the elements and components of Access database.

Stellar Phoenix Access Recovery is robust data recovery software to repair and restore the corrupted Access database files. This software helps you in repairing all the elements of Access database including tables, forms, reports, queries and database relationships. Stellar Phoenix scans for corrupted .mdb (Access database files) files to repair and restore it to a default location or a user specified location on the hard drive.
