Consider a scenario wherein you are working on an MS Access 2000 database. You execute an append query to add few records in a table. You are unable to do so and an error message is displayed, that is:

“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.”

Cause:
The most possible cause of the aforementioned error message is that the table in question has a self-join and Memo field. Also, it has referential integrity enforced upon it. That’s why you are not able to use the append query. Another reason for the error message is that the table is corrupt.

Resolution:
To resolve this error, you should change the Memo fields to Text fields. You can also move the Memo fields to another table and then use a 1:1 relationship between the tables. These methods should be able to resolve the issue. However, if you are still not able to address the situation it means that the table is corrupt. In such case, you should use a third-party Access database repair software to recover Access table. These read-only tools use fast yet sophisticated scanning algorithms to scan the damaged area.

To thoroughly elaborate the above situation, consider a realistic situation wherein you encounter the below error message while trying to open MS Excel 2000 spreadsheet:

“File Error: Data May Have Been Lost”

The above error message does not allow the spreadsheet to open and makes all its saved records inaccessible. The same error message pops up every time you try to open your spreadsheet.

Cause:
The above error message appears when your Excel spreadsheet is logically corrupted.

Resolution:
To get past the above Excel spreadsheet corruption error message, repair the file using the below mentioned steps:

1.Click ‘Open’ under the ‘File’ menu.
2.Choose the corrupt Excel file and click ‘Open’ button.
3.Lastly, click on ‘Open and Repair’ option to repair the spreadsheet.

In case the spreadsheet remains corrupted even after following the above steps, and you have not maintained any backup, then you will need to repair the spreadsheet using an effective third-party Excel Repair application.

Such MS Excel File Repair tools incorporate repairing mechanisms that are competent enough to repair any logically damaged Excel file. The repair tool is easily understandable and is absolutely non-destructive. It allows the user to save the repaired file at user-specified location.

Consider a scenario wherein you have imported an Access database into an MS Excel spreadsheet on which you are working. You have inserted a hyperlink that points to the database. You click on that hyperlink but it fails to open and an error message is displayed:

“Enter password.”

This error is displayed even though you have not assigned a password for the database.

Cause:
There could be various causes for this error message. They are:

• Use of hyperlink in an MS Office application to open the database.
• Use of VBA automation code (if done) in MS Excel to open the database.
• The database is corrupt and you need to repair Access file.

The reason for the first two causes is that you may have compacted the database either manually or by using Compact on Close utility. Because of this, you are prevented from accessing the database, and you are prompted to enter the password on every attempt of opening the access database.

Resolution:
First of all, you should open the database in MS Access to ascertain whether it is corrupt or not. If you are able to open it, then the database is not corrupt. Probably the error message is occurring because of importing the database in non-Access application.
To resolve the error, you should export each object of the database into a new database either using a hyperlink or using VBA automation code. This will help you in recovering the data that is blocked in the database.
However, if you are not able to repair the access file then you should consider using a third-party Access repair tool. These read-only tools recover the database files (both .mdb and .accdb) using sophisticated scanning algorithms, thereby ensuring that the original files are not overwritten.

Consider a scenario wherein you want to import data from a table. You are not able to do so and an error message is displayed:

“Operation failed – too many indexes – reduce the number and try again.”

The error message signifies that the table from which you want to import data is corrupt and, thus, inaccessible.

Cause:
The root cause for this error message is that the index definitions of the table are corrupt. Access first imports the table definition and data, and then tries to apply the indexes. Since the index definitions are corrupt, the table cannot be imported. However, the data in the table is secure but inaccessible.

Resolution:
To resolve this issue, you should create a blank copy of the table. Remove all the indexes from the table and run an append query. Then, move the data from the corrupt table to the new table (in the same file). Now, recreate the indexes. Lastly, move the table to a new file. This should address the issue perfectly. However, if you are still not able to resolve the issue, you should use a third-party access repair tool to repair access file. These tools do not require having sound technical knowledge for access file repair.

A detailed analysis of the above problem can be explained with the help of the below error message:

“End-of-central-directory signature not found. Either this file is not a zip file, or it constitutes one disk of a multi-part archive ”

The above error message appears when you try to open a Zip file. After the error message appears, the Zip file becomes unreadable.

Cause:
The above error message appears when the central directory structure of the Zip file is corrupted or damaged. Few major reasons responsible for the corruption of central directory structure can be improper system shutdown when the Zip file is open, virus attack, and problem with network.

Resolution:
To get over the above error message and to unzip the Zip file, in case of unavailability of backup, you need to search for a powerful third-party Zip File Repair tool. Such repair utilities are most effective in repairing all kinds of logically corrupted Zip files. The repair applications can repair zip files in few simple steps and also allow the user to restore the repaired file at required destination.  In addition, these tools are built with a wizard-style interface that makes them easily understandable, even for those without any prior zip file repair experience.

The above problem can be elaborated using the below error message, which pops up when you try to open an Excel spreadsheet:

“Cannot find the file path (or one of its components). Make sure the path and file name are correct and that all required libraries are available. ”

After the above error message pops up, MS Excel starts but is unable to open the workbook that you double-clicked. The data saved in the Workbook becomes inaccessible after the above error message appears.

Cause:
The above error message appears when spreadsheet is corrupted.

Resolution:
In case the spreadsheet opens blank after the above error message, then you need to:

• Use ‘Revert to Saved Document’ option to recover the original spreadsheet.
• Store the corrupted spreadsheet in SYLK format.
• Store the damaged spreadsheet in HTML (Hyper Text Markup Language) format.

However, if the spreadsheet can not be opened in MS Excel, then you will need to:

• Try to open the spreadsheet in MS Word, MS Excel Viewer or Word Pad.
• Use macros to extract data from a spreadsheet.
• Link the corrupted Excel spreadsheet using external references.

However, if all the above resolutions fail to resolve your issue, then you will need to opt for an effective Excel File Repair application. An Excel Repair tool uses effective repair techniques to repair all logically corrupted spreadsheets.

Consider a scenario wherein you are working on a VBA application that is integrated with an Access database. You open the VBA application but it fails to open. The following error messages may be displayed:
“The Visual Basic for Applications project in this database is corrupt.” OR
“The module name ‘module name’ is misspelled or refers to a module that doesn’t exist.”

When you try to close the database, Access may stop responding or the following error message is displayed.
“An application error has occurred
and an application log is being generated.

MSACCESS.exe
Exception access violation(ox0000005),Address; 0×3002d681”

Note: The actual memory address may vary.

When you try to compact the database, the following error message is displayed.
“The Visual Basic for Applications project in this database is corrupt.”

Cause:
The cause for the aforementioned error messages is that Visual Basic for Applications (VBA) project is corrupted. It became corrupted because of many reasons such as damaged MS Office, improper shutdown, virus infections, etc.

Resolution:
You need to repair Access files by using a third-party access repair tool. These read-only tools enable you to repair databases using complex scanning algorithms without any loss of data.

Microsoft Excel uses .xls or .xlsx file format to store data. Round-tripping spreadsheet data manipulates the way in which the data has been stored, which can ultimately cause corruption.

Consider a realistic problem related to Excel file round-tripping. Suppose you create an important spreadsheet with MS Excel and for some reason, you convert it to HTML format, then in PDF format, and then again in Excel native format- XLS or XLSX. After this, when you try to open the file, it fails to open and shows file corruption errors. Consequently, the critical information of the file becomes inaccessible.

Cause:
Microsoft Excel spreadsheet becomes corrupted due to continuous round-tripping between various file formats.

Solution:
To extract the data, you should try following measures:

• If you can open the file, try copying its data (or only the uncorrupted data) to a new Excel spreadsheet
• You can also try opening the file in Microsoft Excel Viewer
• If there is chart that is linked to the corrupted Excel file, you can use a macro to retrieve all possible data.

In case the above methods fail to work, you should delete the corrupted file provided a good backup is available. In other cases, the only solution is to use a third-party utility to Repair Excel spreadsheet.

Consider a scenario wherein you are the system administrator in your organization. You have been given the responsibility to routinely take the backup of all the systems. You took the backup of the systems over the network. Due to some inconsistency in the network connection when you are trying to restore the systems, an error is displayed.

“An inconsistency was encountered in the requested backup file”

Cause:
The main cause for this error could be that the .bkf file was not created successfully over the network. Because of this, the .bkf file may have got damaged and thus, unable to restore the data.

Resolution:
If you find out that the backup file is not created successfully so before losing out the original data, create the backup of the data using the NTBackup utility as soon as possible. However, if you are still facing this problem, then you need to perform the BKF repair on the corrupted .bkf file.

To recover the .bkf file, you will have to use a powerful and efficient bkf recovery tool. These tools are well-designed to scan the .bkf file using effective algorithms to retrieve as much data as possible.

Microsoft PowerPoint is a powerful presentation tool that is used to create attractive and informative presentations by educators, students, trainers, and professionals all over the world.
