skinning windows

hi
I wrote a skinned window(based on some tutorial I found on the net).Ididn't understand the
tute very well. In my code there are two functions called clswin() and void creatergn(). when i put these functions under WM_CREATE didn't work.when i put these functions under winapi main() it worked. any one know why???
I have attached the project.

second question is what is the usage of bitblt()?
and also can any on explain what exactly happen in this code??

I'm using VC++ 6.0
WinXp xp2
thanks.

please try to write clswin() and creatergn() in WM_CREATE event.
why dont you develop your project on MFC?
i think your skin windows is easy on it.

Had a quick look and i think it's because the value of the global variable "hwnd" is only set AFTER CreateWindow is finished, but WM_CREATE is called before CreateWindow is finished (i think). The functions "creatergn" and "clswin" use this global variable. This may work:

Code:

---

void creatergn(HWND hwnd)
{
       
        rgnfile =FindResource(GetModuleHandle(NULL),MAKEINTRESOURCE(IDR_RGN),"BINARY");
        pSkinData = (LPRGNDATA)LoadResource(NULL, rgnfile);
        rgnSkin = ExtCreateRegion(NULL, SizeofResource(GetModuleHandle(NULL),rgnfile), pSkinData);
        SetWindowRgn(hwnd,rgnSkin,TRUE);
       
}

void clswin(HWND hwnd)
{
       
        DWORD dwStyle;
        dwStyle = GetWindowLong(hwnd, GWL_STYLE);
        dwStyle &= ~(WS_CAPTION|WS_SIZEBOX);
        SetWindowLong(hwnd, GWL_STYLE, dwStyle);
        InvalidateRect(hwnd, NULL, TRUE);
        SetWindowPos(hwnd, NULL, 0,0,504,360, SWP_NOMOVE|SWP_NOZORDER);
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    HDC        hdc ;
    PAINTSTRUCT ps ;
       
static        BOOL regned =FALSE;       
   
                       
    switch (message)
    {
  case WM_CREATE:

          creatergn(hwnd);
          clswin(hwnd);
          loadbitmap();
               
                               
          return 0 ;

        case WM_LBUTTONDOWN:
                  SendMessage(hwnd, WM_NCLBUTTONDOWN,HTCAPTION,0);
                  break;
                       
    case WM_PAINT:
                       
          hdc = BeginPaint (hwnd, &ps) ;
                 
                  skinme(ps.hdc);
          SetBkMode(ps.hdc,TRANSPARENT);
          EndPaint (hwnd, &ps) ;
          return 0 ;

                 
                         
    case WM_DESTROY:
               
          PostQuitMessage (0) ;
          return 0 ;

        case WM_CLOSE:
                        DeleteDC(bitdc);
                        DeleteObject(rgnSkin);       
                        FreeResource(pSkinData);
                         

    }
    return DefWindowProc (hwnd, message, wParam, lParam) ;
                 
}

You need to ask yourself if it's necessary to use these global variables.

MFC is not freeware. D'oh!

It works. thanks guys.Making hwnd global is a bad idea right .
thanks for showing me that.
Is it possible to use same thing to the dialog boxes??
