this is a classic case of having mixed up jumbles of debug and non-debug
(release) code calling each other through inadvertant dynamic linking, object
registration, etc...

somewhere, you are doing this too.. as you run your app under the de*,
watch the output window (alt-2 i think) as it tells you what dlls are being
loaded. you should see one that is not a debug dll...or just check your project
settings and see who is being loaded improperly.

1. Help: finding the right set of MFC/DAO DLLs

Hi all,

We are trying for sometime to reveal the right set of DLLs we shoudl install
with our application. The application characteristics are:
* Built on VC++ 6.0 (with Service Pack 3)
* Using MFC as a shared DLL
* Using DAO 360 objects (to access Access database)

What we ahve found so far is that if we install the following applications,
then the DLLs are there, and the application works:
1. Visual C++ 6.0
2. Service Pack 3 for Visual C++ 6.0
3. Office 2000

I know that some of the DLLs requires not only copying but also registering,
and that there are special setup applications for that.
Any ideas what DLLs shoudl we install? Where we can find the documentation?

Thanks for any hint,
Lior Messinger,
