Hello!

I want to implement one function which checks if one file (e.g. 'test.exe' will be overwritten during a installation if the file version of the installed file is older than the file version in the install package.
To check the file version of the installed file 'test.exe' is not the problem, but how can I get the file version from the file to be installed ('test.exe' from the installer database?
My idea is to open the installer database with this code:

hDatabase=MsiGetActiveDatabase(hMSI);
strQuery="SELECT Version FROM File WHERE FileName='test.exe'";
nResult = MsiDatabaseOpenView(hDatabase,strQuery,hView);

So I get a database view called "hView", but I can't get the "version" from this view because I don't know how to extract information from a view and I couldn't also find any information about that.
Maybe my way is wrong and anyone knows another solution for my problem, this would be really great.
Otherwise if anybody could help me with the extraction from a view...

Thanks for everything and for your help.

You are on the right track.
Now you call MsiViewExecute, MsiViewFetch and then MsiRecordGetString

Sorry, but after a long time I tried to solve my problem, but I had no luck.
Is anyone here able to help me again with some more details?

Thank you very much.
