在C++BUILDER中，如何将整个窗体保存成图片？？

[porscheii]

就是通过程序实现，拷屏的功能。

[Y___Y]

这个简单，用个api函数BitBlt就搞定了

[___NULL]

bitmap 获得当前窗体的画面

void __fastcall CopyActiveWindowClick(Graphics::TBitmap* bitmap)
{
TRect rect;
HWND WinHandle =GetTopWndHandle();
GetWindowRect(WinHandle,&rect);
CaptureWndImage(rect);

bitmap->Width=awBitmap->Width;
bitmap->Height=awBitmap->Height;
bitmap->Canvas->Draw(0,0,awBitmap);
}

[___NULL]

/// 还有一段

void __fastcall CaptureWndImage(TRect rect)
{
awBitmap->Width = rect.Right - rect.Left;
awBitmap->Height = rect.Bottom - rect.Top;
HDC ScreenDC= GetDC(0);
try
{
StretchBlt(awBitmap->Canvas->Handle, 0, 0,
awBitmap->Width, awBitmap->Height, ScreenDC,
rect.Left, rect.Top,
awBitmap->Width,
awBitmap->Height,
SRCCOPY);
}
__finally
{
ReleaseDC(0, ScreenDC);
}
}
