Delphi 截圖的問題,有代碼,請高手幫幫

var C: TCanvas; b: TBitmap; H: HDC; R: TRect; hand: THandle;

p: TPoint;

J: TJpegImage;

m, n: INTEGER;

name: array[0..255] of char;

begin

B := TBitmap.Create;

C := TCanvas.Create;

GetCurSorPos(P); //取得鼠標所在區域坐標

Hand := WindowFromPoint(P); //取得坐標所在窗體句柄

FillChar(name, SizeOf(name), #0); //

GetWindowText(Hand, name, 255); // 取得窗口標題

if name = '' then CopyMemory(@name, PCHAR(inttostr(hand)), Length(inttostr(hand)) + 1); //用句柄

if hand = 0 then exit;

H := GetWindowDC(Hand); //獲取整個窗口（包括邊框、滾動條、標題欄、菜單等）的設備場景 返回值 Long

try

GetWindowRect(hand, R); //取得句柄對應窗體的矩形區域

B.Width := R.Right - R.Left;

B.Height := R.Bottom - R.Top;

C.Handle := H; //將描述表賦給畫布的句柄，此時畫布就代表整個屏幕了

B.Canvas.CopyRect(Rect(0, 0, B.Width, B.Height), C, Rect(0, 0, B.Width, B.Height));

//Image1.Picture.Bitmap.Assign(B);

finally

C.Free;

B.Free;

ReleaseDC(Hand, H); //釋放設備上下文環境

end;

end;

以前寫的壹個類似軟件 ，應該和妳的問題相符，妳可以參考壹下。
