Ive written a little tool which calculates a CRC32 of a file and now i want to add an entry to the contextmenu which appears, if you right-click an icon in the explorer. Ive already checked out the registry for other programms which use this ability and it seems to work with DLLs. Can anybody give me a clue how to do this ?
Im using WinXP and Visual C++ 5.0.
