我使用TMediaplayer將影像show在panel上，並想用BitBlt的方式將影像顯示在TImage元件上，可是失敗了...以下是我的程式碼，不知道是哪裡有錯呢？ 亦或是TMediaplayer不支援以下方式的擷圖？ 麻煩各位了，謝謝 < class="code"> if(this->OpenDialog1->Execute()) { Graphics::TBitmap *BMP = new Graphics::TBitmap; TPoint getPoint; HDC aDC; this->MediaPlayer1->FileName = this->OpenDialog1->FileName; this->MediaPlayer1->Open(); this->Panel1->Width = this->MediaPlayer1->DisplayRect.Width(); this->Panel1->Height = this->MediaPlayer1->DisplayRect.Height(); BMP->Width = this->MediaPlayer1->DisplayRect.Width(); BMP->Height = this->MediaPlayer1->DisplayRect.Height(); this->MediaPlayer1->TimeFormat = tfFrames; getPoint = this->Panel1->ClientToScreen(Point(0,0)); aDC = GetDC(0); this->MediaPlayer1->Position = 20; Application->ProcessMessages(); BitBlt(BMP->Canvas->Handle, 0,0,BMP->Width,BMP->Height,aDC, getPoint.x, getPoint.y, SRCCOPY); this->Image1->Picture->Bitmap = BMP; this->Image1->Invalidate(); }
