灌水 - "畫面擷取"革命性的發展

[魔術王子]

Windows擷取畫面的按鈕SrtScr雖然方便,可惜沒有加入游標的功能
幸好現在有很多相當方便的工具可以達到
之前小王子也分享過利用BCB設計畫面擷取的程式,而且透過GetCursorInfo API指令將游標加入
可惜加入游標的方法只能用在全螢幕擷取,一旦要擷取特定視窗就沒轍了
不過今天小王子終於克服這個問題,同樣的分享程式碼給大家
擷取畫面的方法還真不少,下面的方法是監控剪貼簿,當然同樣是擷取全螢幕
只不過,擷取完後,會取得上層視窗的位置及大小,對應到剛剛擷取的畫面,就可取得想要的視窗啦

分享一下程式
不過這是用BCB6.0設計的,新版BCB編譯可能會因為字元出錯,以後有機會再設計吧,有幾個地方說明一下
1.雙擊右下角圖示改變圖示開關監控

    case WM_LBUTTONDBLCLK:
      Timer1->Enabled=!Timer1->Enabled;
      if(Timer1->Enabled) {
        Clipboard()->Clear();
        ListView1->Tag=0;
        Clip2Bmp.hIcon=LoadIcon(HInstance,"Clip2Bmp1");
        strcpy(Clip2Bmp.szTip,"監控中");
      } else {
        Clip2Bmp.hIcon=LoadIcon(HInstance,"Clip2Bmp2");
        strcpy(Clip2Bmp.szTip,"閒置中");
      }
      Shell_NotifyIcon(NIM_MODIFY,&Clip2Bmp);
//      ShowWindow(Application->Handle,SW_RESTORE);
//      ShowWindow(Handle,SW_RESTORE);
      break;

2.右上角"關閉'按鈕

void __fastcall TForm1::FormCloseQuery(TObject *Sender, bool &CanClose)
{
  ShowWindow(Application->Handle,SW_HIDE);
  ShowWindow(Handle,SW_HIDE);
  CanClose=(Tag==1);
}
//---------------------------------------------------------------------------

3.還有SHBrowseForFolder使用

  String WorkDir;
  BROWSEINFO bi;
  char WDir[MAX_PATH];
  char FolderName[MAX_PATH];
  LPITEMIDLIST ItemID;
  memset(&bi, 0, sizeof(BROWSEINFO));
  memset(WDir, 0, MAX_PATH);
  bi.hwndOwner = Handle;
  bi.pszDisplayName = FolderName;
  bi.lpszTitle = "請選擇路徑";
  ItemID = SHBrowseForFolder(&bi);
  SHGetPathFromIDList(ItemID, WDir);
  WorkDir = String(WDir);
  if(WorkDir!="") StatusBar1->SimpleText=WorkDir+"\\";
  ScanFile();

注意藍字部分,才能使用SHBrowseForFolder
