Debugging a Domino/Notes DSAPI filter

Question

I've built a DLL for Domino Server 8.5 for Windows and installed it as a DSAPI filter, but every time I restart Domino I get "HTTP Server: Failed to load DSAPI module C:\path_to_filter\filter.dll"

Is there any way to determine why this is failing to load?

I built the DLL from a C++ project in Visual Studio 2008 and used the libraries and includes from the Lotus C API for Notes/Domino 8.5. I copied most of the code from the sample DSAPI filter, but stripped out most of the actual functionality so that I can fill it in with my own. It doesn't seem to be an error with the code, as I've been unable to find an actual exception at this point.

Answer 1

Get depends.exe, and run it on your DLL. It will show you what other DLLs it loads, and the errors when it cannot find one of them.

Answer 2

Try setting debug_dsapi=10 in your server ini and analyze it's output for what errors might be thrown
