How to capture the screen with the “Tool Tips”?

Question

I am using GDI to capture the screen, and I have noticed that the \"Tool Tips\" are not included in the screenshot. This is my basic code:

HDC hdcDesk = GetD

Update: added CAPTUREBLT as suggested by Alex K., Adrian McCarthy et al.

I can't reproduce the same problem. If you succeed in taking screen shot of desktop then everything should be there! Try this code instead. Note the 3 second wait is supposed to give time to manually activate a tool tip.

int main()
{
    Sleep(3000);
    TCHAR* filename = TEXT("c:\\test\\_bmp.bmp");
    int width = GetSystemMetrics(SM_CXFULLSCREEN); 
    int height = GetSystemMetrics(SM_CYFULLSCREEN); 

    HDC hdc = GetDC(HWND_DESKTOP);
    HBITMAP hbitmap = CreateCompatibleBitmap(hdc, width, height);
    HDC memdc = CreateCompatibleDC(hdc);
    HGDIOBJ oldbmp = SelectObject(memdc, hbitmap);
    BitBlt(memdc, 0, 0, width, height, hdc, 0, 0, CAPTUREBLT | SRCCOPY);

    WORD bpp = 24; //24-bit bitmap
    DWORD size = ((width * bpp + 31) / 32) * 4 * height;
    BITMAPFILEHEADER filehdr = { 'MB', 54 + size, 0, 0, 54 };
    BITMAPINFOHEADER infohdr = { 40, width, height, 1, bpp };

    std::vector bits(size);
    GetDIBits(hdc, hbitmap, 0, height, &bits[0], (BITMAPINFO*)&infohdr, DIB_RGB_COLORS);

    std::ofstream f(filename, std::ios::binary);
    f.write((char*)&filehdr, sizeof(filehdr));
    f.write((char*)&infohdr, sizeof(infohdr));
    f.write((char*)bits.data(), size);

    SelectObject(memdc, oldbmp);
    DeleteObject(memdc);
    DeleteObject(hbitmap);
    ReleaseDC(HWND_DESKTOP, hdc);
    ShellExecute(0, 0, filename, 0, 0, SW_SHOW);

    return 0;
}
