Virtual Key Codes

Ok then... Where are you telling me to put "return 0;"???

Right after your processing code for VK_LEFT/VK_RIGHT of WM_KEYDOWN message.

Thanks :)

The left and right arrow key is now working as it should, although when i press a key such as 'S' or any other key which I have not defined code for makes my icon move right.

Show your actual code.

Code:

---

case WM_KEYDOWN:

                        switch(wParam)
                       
                                case VK_LEFT:
                        {
                                        X -= 5;
                                        InvalidateRect(hWnd, NULL, TRUE);
                                        return 0;

                                       
                                       
                        }
                                case VK_RIGHT:
                        {
                                        X += 5;
                                        InvalidateRect(hWnd, NULL, TRUE);
                                        return 0;
                                       
                                       
                        }

                        break;

---

Try:

Code:

---

case WM_KEYDOWN:
{
  switch(wParam) {
    case VK_LEFT:
        X -= 5;
        InvalidateRect(hWnd, NULL, TRUE);
        break;
    case VK_RIGHT:
        X += 5;
        InvalidateRect(hWnd, NULL, TRUE);
        break;
  }
}
return(0);
break;

---

Besides, the line, hInstance = LoadLibrary (TEXT("Application01.exe"));, is run every time a message arrives, which might occur several dozen of times per seconds. That line might take a lot of time and resources. I would advise you to load that library only in WM_CREATE, and declare hInstance as a static variable.

Actually, GetModuleHandle(NULL) would be enough, as long as it is about getting main .exe instance handle.

If it is, the instance handle is passed into WinMain(), and is typically saved in a global variable.

I'm almost sure it is, as nobody loads external .exe to the process. :)
