Change EXE's icon; not so easy

[NewWin32]

I was given this workspace with many projects; I said I could change the icon of the Executable. Easy I thought (and said to my friend), just find the RC file and make the appropriate changes.

Not so easy, their is no .RC file, no resources at all, so I had to forget the LoadIcon( hWnd, MAKEINTRESOURCE( IDC_MY_ICON ) );

Even adding a "resource | icon" simply added a "ico" file in the project tree.


-> So how can I change the icon of the EXE displayed in explorer (and shortcuts)?.

I did found a WinMain, but it is one like I never saw before. Basicly I have only the hInstance, Here is the code:

S32 PASCAL WinMain( HINSTANCE hInstance, HINSTANCE, LPSTR lpszCmdLine, S32)
{
   Vector<char *> argv;
   char moduleName[256];
   GetModuleFileName(NULL, moduleName, sizeof(moduleName));
   argv.push_back(moduleName);

   for (const char* word,*ptr = lpszCmdLine; *ptr; )  {
      // Eat white space
      for (; dIsspace(*ptr) && *ptr; ptr++)
         ;
      // Pick out the next word
      for (word = ptr; !dIsspace(*ptr) && *ptr; ptr++)
         ;
      // Add the word to the argument list.
      if (*word) {
         int len = ptr - word;
         char *arg = (char *) dMalloc(len + 1);
         dStrncpy(arg, word, len);
         arg[len] = 0;
         argv.push_back(arg);
      }
   }

   winState.appInstance = hInstance;

   S32 retVal = run(argv.size(), (const char **) argv.address());
   
   for(U32 j = 1; j < argv.size(); j++)
      dFree(argv[j]);

   return retVal;
}

If you are wondering this is from "GarageGames" Torque 3D engine, my friend is making a small game just for fun (he is not a professional coder, but a real good amateur).

This might help, the "winState" structure (but I am not sure of the initialization order ....)

struct Win32PlatState
{
   FILE *log_fp;
   HINSTANCE hinstOpenGL;
   HINSTANCE hinstGLU;
   HINSTANCE hinstOpenAL;
   HWND appWindow;
   HDC appDC;
   HINSTANCE appInstance;
   HGLRC hGLRC;
   DWORD processId;

   S32 desktopBitsPixel;
   S32 desktopWidth;
   S32 desktopHeight;
   U32 currentTime;
   
   Win32PlatState();
};

Win32PlatState winState;

Any insight appreciated ...

When you say there are no resources, are you speaking of just the .RC file, or do you mean there are no .ICO/.BMP 's, etc, anywhere in the project?

Is there currently a custom icon being used, or is it using the default application icon? If a custom icon is being used, you might start by searching the project (in the source code) for the filename of that icon.

It is hard to get much out of the code snippet you posted, as there are many user defined variables and functions. I think I would start by looking into that "run" function.

Try searching for any calls to RegisterClass/RegisterClassEx, and look for where the WNDCLASS/WNDCLASSEX structure is filled in, and see what is used for the HICON member. You might also try searching for any calls to LoadIcon or LoadImage, etc.
