我的程式是要做我所抓到影格之間做相減 取得相減的值可以SHOW在CHART上面 可是執行之後就會停住 不知道是發生什麼問題 可以請高手們解答一下嗎  謝謝    Graphics::TBitmap *MyBmp;         TCanvas *MyCanvas;         HDC dc;         TRect rect;         String name;         AnsiString tempIndex,temp;         Graphics::TBitmap *TheBitmap;         Graphics::TBitmap *OneBitmap;         Byte *ptr1,*ptr2,*ptr3;         int Width, Height,x;         int aa=MediaPlayer1->TrackLength[1];         temp=IntToStr(aa).Length();         tempIndex=pow(10,StrToInt(temp));         if(StrToInt(EndPos->Text)<=aa)         {                 for(int i=StrToInt(StartPos->Text);i<=StrToInt(EndPos->Text);i=i+StrToInt(CRatio->Text))                 {                         MediaPlayer1->Position=i;                         MyBmp=new Graphics::TBitmap ;                         MyCanvas=new TCanvas ;                         rect=MediaPlayer1->DisplayRect ;                         dc=GetDC(Panel1->Handle);                         MyCanvas->Handle=dc;                         MyBmp->Width=rect.Right-rect.Left ;                         MyBmp->Height=rect.Bottom-rect.Top ;                         MyBmp->Canvas->CopyRect(rect,MyCanvas,rect);                         {                         if (i=StrToInt(StartPos->Text))                            OneBitmap=MyBmp;                         else                           {                           for(int y=0;yHeight;y ) { ptr1=(Byte *)MyBmp->ScanLine[y]; ptr2=(Byte *)OneBitmap->ScanLine[y]; for(int x=0;xSeries[0]->AddXY(x,ptr3[x],""); } ReleaseDC(0,dc); delete MyBmp; delete MyCanvas; } }
