Help finding MDAC version and checking if a dll is shared

[t-tex]

Hi,

I would like to find out first if MDAC is installed at all and then which version that is installed. Does anyone have any input on this?

Also, is there a way to find out if a dll is shared so that it can be removed?

Best regards,
Pontus

Hi again,

Since I got no replies I assume that no one has a solution for this problem. So I solved it by creating two small c++-programs that did the job for me.

The only thing I can think of is 'registry, registry', that there might be some key which is created by MDAC.

Also, a reference count of DLL's is kept somewhere, but I don't know where.

Not a very useful reply, because I don't really know. Sorry.

You can check for the MDAC version in the registry ... this article will help.

And I'm planning on writing a function for this and putting it in the archives, later today.

You'd better parse that string and compare the version number, to make it support any future versions.

That's on the "to do" list. I just wanted to get an example up since I was looking early this AM for something similar, found nothing, and wanted to get something into my installer quickly. :)

Thanks!
