Can a Windows dll retrieve its own filename?
I think you're looking for GetModuleFileName.

{ If you are working on a DLL and are interested in the filename of the DLL rather than the filename of the application, then you can use this function:}function GetModuleName: string;var szFileName: array[0..MAX_PATH] of Char;begin FillChar(szFileName, SizeOf(szFileName), #0); GetModuleFileName(hInstance, szFileName, MAX_PATH); Result := szFileName;end;Untested though, been some time since I worked with Delphi :)
