So I've been beating my head against a wall for the past few days trying to get this to work. I've tried countless samples from the net and even the MSDN sample.
I just can't get it to work, Explorer NEVER seems to call my DLL. I recently created another Explorer extension for the Preview Pane and that went pretty smoothly, but I just can't figure out what's going wrong.
I've tried 32-bit systems, visual studio 2005 & 2008, nothing seems to work. The registration goes smoothly, I add the necessary registry nodes, but the DLL is never called. I had another developer try the MSDN sample as well, with no success. Does anyone have any ideas?
