I’m writing a small MFC application to talk to Access databases using the ADO

  • 0

I’m writing a small MFC application to talk to Access databases using the ADO method. Problem is it works on some computers (mostly newer, Windows 7 SP1) but not on older ones, and I really need to fix this or I don’t have a application.

The error is a typically informative “App has stopped working”, so no news there.

I initially import the database using 

#import "libid:B691E011-1797-432E-907A-4D8C69339129" \
rename( "EOF", "AdoNSEOF" )

which is the UUID for MSAdo60.tlb. I connect to it using the following connection string:

Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+dbPath+";

Both machines have both msado15.dll and mado60.tlb. I’ll need to check versions.

    Just solved this with knowledge base 2640696 and dropping the UUID for msado15.dll. Microsoft considerately broken the interface moving to W7SP1.
