Şeffaf win32 penceresi ve metni

Question

Tam ekran şeffaf, kenarlıksız bir pencere oluşturmaya çalışıyorum. Metin arka planı şeffaf olmalı, ancak gerçek yazı tipi yüzü olmamalıdır. Sorun şu ki, yalnızca SetWindowRgn yapmazken görüntülenen TextOut'u görebiliyorum. . Ben yanlış ne yapıyorum :(

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow) 
{ 
    HWND hWnd; 
    hInst = hInstance; 

    DWORD Flags1 = WS_EX_COMPOSITED | WS_EX_LAYERED | WS_EX_NOACTIVATE | WS_EX_TOPMOST | WS_EX_TRANSPARENT; 
    DWORD Flags2 = WS_POPUP; 

    hWnd = CreateWindowEx(Flags1, szWindowClass, szTitle, Flags2, 0, 0, 1920, 1200, 0, 0, hInstance, 0); 

    if(!hWnd)return FALSE; 

    HRGN GGG = CreateRectRgn(0, 0, 0, 0); 
    SetWindowRgn(hWnd, GGG, false); 

    ShowWindow(hWnd, nCmdShow); 
    UpdateWindow(hWnd); 

    DeleteObject(GGG); 

    return TRUE; 
} 

    case WM_PAINT: 
    hdc = BeginPaint(hWnd, &ps); 

    SetBkMode(hdc, TRANSPARENT); 
    TextOut(hdc, 50, 50, L"MY TEXT", lstrlen(L"MY TEXT")); 

    EndPaint(hWnd, &ps);

böyle bu Çözüldü hiçbir fikrim yok:

BOOL InitInstance(HINSTANCE hInstance, int nCmdShow) 
{ 
    HWND hWnd; 
    hInst = hInstance; 

    DWORD Flags1 = WS_EX_COMPOSITED | WS_EX_LAYERED | WS_EX_NOACTIVATE | WS_EX_TOPMOST | WS_EX_TRANSPARENT; 
    DWORD Flags2 = WS_POPUP; 

    hWnd = CreateWindowEx(Flags1, szWindowClass, szTitle, Flags2, 0, 0, 1920, 1200, 0, 0, hInstance, 0); 

    if(!hWnd)return FALSE; 

    HRGN GGG = CreateRectRgn(0, 0, 1920, 1200); 
    InvertRgn(GetDC(hWnd), GGG); 
    SetWindowRgn(hWnd, GGG, false); 

    COLORREF RRR = RGB(255, 0, 255); 
    SetLayeredWindowAttributes(hWnd, RRR, (BYTE)0, LWA_COLORKEY); 

    ShowWindow(hWnd, nCmdShow); 
    UpdateWindow(hWnd); 

    DeleteObject(GGG); 

    return TRUE; 
} 

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) 
{ 
    int wmId, wmEvent; 
    PAINTSTRUCT ps; 
    HDC hdc; 
    RECT rect; 

    switch (message) 
    { 
    case WM_ERASEBKGND: 

     GetClientRect(hWnd, &rect); 
     FillRect((HDC)wParam, &rect, CreateSolidBrush(RGB(255, 0, 255))); 

     break;
