我的做法如下：发现如果程序界面打开后正常，一旦程序最小花或者放到系统托盘里后，就截不到程序里的图片了。请问有办法解决么。谢谢
TRect r,r1;
int i,j,temp;
Graphics::TBitmap *Dest= new Graphics::TBitmap();
GetWindowRect(Form1->Handle ,&r);
Dest->Width=Image2->Width ;
Dest->Height=Image2->Height;
DC=GetWindowDC(Form1->CppWebBrowser1->Handle);
BitBlt (Dest->Canvas->Handle ,0,0,Dest->Width,Dest->Height,DC,160,118,SRCCOPY);
Image2->Picture->Bitmap =Dest;
Image2->Picture->SaveToFile("c:\\aa.bmp");
