Ordinal 12345 could not be located in dynamic link library

When running my freshly built application, I get the following error message:

Ordinal 12345 could not be located in dynamic link library mfc90u.dll

Apparently, my application calls a function that is not present in the given .开发者_高级运维DLL. Is there a way to determine which part of my source code that calls this function?

Update: I think I'm beginning to understand what's going on.

Dependency Walker can be an invaluable tool for problems like this.

You should be able to use dumpbin /exports mfc90u.lib to find the function that is associated with ordinal 12404. This error typically occurs when the .lib does not match the .dll.
