Make Application.ExeName work in DLLs (Views: 101)


Problem/Question/Abstract:

When you work with DLL you will discover that Application.ExeName will not return the DLL filename, but the filename of the application that loaded your library. That's a problem in some cases. You can use the GetModuleFileName to achieve this problem.

Answer:

In Forms.pas, at line 6856 you'll find:

function TApplication.GetExeName: string;
begin
  Result := ParamStr(0);
end;

for DLLs you can use this:

function GetRealExeName: string;
var
  ExeName: array[0..MAX_PATH] of char;
begin
  fillchar(ExeName, SizeOf(ExeName), #0);
  GetModuleFileName(HInstance, ExeName, MAX_PATH);
  Result := ExeName;
end;

now, this will return also DLL file names.
