There are many softwares with great looking skins, among which are: Sonique, WinAmp, ZoneAlarm, etc.
I wish to create my own skinned window/software.
NOTE: I do not wish to overwrite the default window, but rather create a new one from scratch, and with any shape i choose.

Thank you, Bitwize.

you could try looking into Mozilla's use of XUL

too bad you're not on GNOME or KDE.. ^^;

you can create a window you like. you just have to create a window with correct styles and properties. without title, borders, min-max buttons ... perhaps transparent. and you have to do the right things answering to the messages WM_PAINT, NC-messages and so on. f.e. showing a bitmap. just create a basic windows application and play a little bit with the styles of the main-window and the WM_PAINT - message. you will see what i mean. i don't know if it's possible using delphi or cbuilder, but it's easy using legacy windows programming.

I have already played quite a lot with the CreateWindow function and its styles... perhaps something is eluding me... would you be so kind to display the necessary code?

Well, i try to copy parts of a project, maybe i deleted to much. in this project i created a bitmap-resource, which is to be used as backgroud-image of the window.
At first the main. look at --->>>. the bitmap is loaded there.

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR szCmdLine, int iCmdShow) {
    MSG msg;
    WNDCLASSEX wc;
    HINST = hInstance;

    wc.style=CS_HREDRAW|CS_VREDRAW;
    wc.lpfnWndProc=(WNDPROC)WndProc;
    wc.cbClsExtra=0;
    wc.cbWndExtra=0;
    wc.hInstance = hInstance;
    wc.hIcon = NULL;
    wc.hCursor = LoadCursor(NULL,IDC_ARROW);
    wc.hbrBackground = NULL;
    wc.lpszMenuName = NULL;
    wc.lpszClassName = "MAIN";
    wc.cbSize=sizeof(WNDCLASSEX);
    wc.hIconSm = wc.hIcon;
    if (!RegisterClassEx(&wc)) {return FALSE;}
   
     HWND_MAIN = CreateWindowEx(NULL, "MAIN", "", WS_POPUP, 0, 0, 640, 480, NULL, NULL, HINST, NULL);

       --->>> HBITMAP_BACK = LoadBitmap(HINST, MAKEINTRESOURCE(IDB_BACK));
        SetWindowPos(HWND_MAIN, NULL, 0, 0, 0, 0,SWP_SHOWWINDOW|SWP_NOSIZE|SWP_NOMOVE);

         while(GetMessage(&msg, NULL, 0, 0)) {
          TranslateMessage(&msg); DispatchMessage(&msg);
    }
    return(msg.wParam);
}




and now the WM_PAINT

case WM_PAINT: {
            PAINTSTRUCT ps;
            HDC h = BeginPaint(hWnd, &ps);
            SelectObject(h, HFONT_BASIC);
            SetTextColor(h, RGB(255, 255, 255));
            SetBkColor(h, 0);
               if (h == NULL) {return 0;}
            if (HDC_MEM == 0) {
                HDC_MEM = CreateCompatibleDC(h);
           
                SelectObject(HDC_MEM, HBITMAP_BACK);
                BitBlt(h, ps.rcPaint.left, ps.rcPaint.top, ps.rcPaint.right - ps.rcPaint.left, ps.rcPaint.bottom - ps.rcPaint.top, HDC_MEM, ps.rcPaint.left, ps.rcPaint.top, SRCCOPY);
            }

Nothing else than copying the bitmap to client-rect of the window. Now you can BitBlt other things, f.e. your special controls ...........

Yes my friend, you have deleted too much.
It seems to me, this fragment of code is designed to put a bitmap as a window background but does not put it INSTEAD of the window (which is what i look for).

you should describe what you want. do you want to have an exclusive screen? then you should have a look at direct draw etc. if you want to have a user-designed window, which can be put in the foreground, background, can be moved around and so on, you should create a simple window and only alter the appearance and the behaviour. and that's what i did. or do you want to have a window with a user defined shape? f.e. a circle?

In simple words:
  1. A user defined shape.
  2. Appearance is 100% user made.
  3. The ability to move it around the screen.

For example:
  Draw a triangular bitmap on screen, move it, resize it, make it ACT like a window.

you still should create a window in the normal way, no borders and so on. then you must reduce painting and user interaction to the region you want. it can be done using the region-api-calls. it's an exhausting job - but works.
