In our company we are unfortunately bound to develop and maintain certain programs on the basis of ms access. The challenge we face is to put the programs in a proper version management system.
An Access database is unfortunately only a file in which sub-documents are located.
These could be exported manually, but the internal dependencies, for example a defined view on several external and internal tables, are difficult to maintain.
During our research we found the following answer as a general solution to our problem
How do you use version control with Access development?
Here a script is described that disassembles the access file and makes it versionable.
Copy of the script:
decompose.vbs:
If (WScript.Arguments.Count = 1) then
sExportpath = ""
else
sExportpath = WScript.Arguments(1)
End If
exportModulesTxt sADPFilename, sExportpath
If (Err <> 0) and (Err.Description <> NULL) Then
MsgBox Err.Description, vbExclamation, "Error"
Err.Clear
End If

If (sExportpath = "") then
sExportpath = myPath & "\Source\"
End If

( Script from: https://stackoverflow.com/users/54420/josh-stodola taken from: How do you use version control with Access development? On: 25.01.2020 (DDMMYYYY) )
However, here we encounter the problem that when disassembling the reports the script crashes.
(exception 80010105)
Are there better solutions for our problem or is there an idea why the error occurs ?
