Detect the full path and file name of where the DLL is running from? (Views: 100)


Problem/Question/Abstract:

How can I detect (from a dynamic link library) the full path and file name of where the DLL is running from?

Answer:

The following example demonstrates a dll function that will detect the full path of where the dll was loaded from.

Example:

uses Windows;

procedure ShowDllPath stdcall;
var
  TheFileName: array[0..MAX_PATH] of char;
begin
  FillChar(TheFileName, sizeof(TheFileName), #0);
  GetModuleFileName(hInstance, TheFileName, sizeof(TheFileName));
  MessageBox(0, TheFileName, 'The DLL file name is:', mb_ok);
end;
