Delphi 调用一截图工具进行截图的方法《LceMeaning》

以下代码经本人在Delphi XE2下编写并通过。

procedure TForm5.img1Click(Sender: TObject);
var
 i : Integer;
begin
  try
    if img1.Picture.Graphic = nil  then
         begin
            if MessageBox(Handle, PChar(' 是否需要截图? 点击 ''''是(Y)'''' 后请等待1秒进入截图!                                         '),
                  PChar('截图工具'), MB_ICONINFORMATION or MB_YESNO or MB_DEFBUTTON1) = IDNO then
                 Exit;
            Hide;
            ICSystem.Form1.Hide;
            Sleep(700);
            i := WinExecAndWait32('PrintScreen.exe',True);
            ICSystem.Form1.Show;
            Show;
            if i = 0 then
              img1.Picture.LoadFromClipboardFormat(CF_BITMAP,ClipBoard.GetAsHandle(CF_BITMAP),0);
         end
    else
      begin
        with TForm6.Create(Application) do
          begin
            imgSimg.Picture.Graphic := img1.Picture.Graphic;
            ShowModal;
            if ModalResult = mrCancel then
              begin
                Free;
              end;
          end;
      end;
  except

  end;
end;
