擷取表單控制代碼：通過表單標題模糊查詢

對於 HWND FindWindow(          LPCTSTR lpClassName,
    LPCTSTR lpWindowName
);
lpWindowName必須和查詢表單標題完全相等情況下才可正確返回表單控制代碼，比如若想查詢表單"無標題-記事本"
CString strTitle = _T("無標題-記")
FindWindow(NULL, (LPCTSTR)strTitle)則無法擷取到表單控制代碼

通過EnumWindows方法則可以實現表單模糊查詢

HWND hWndWindow;
CString global_strTitle;
#define  MAX_TITLE_LENGTH 255

BOOL CALLBACK EnumWndProc(HWND hwnd,
        LPARAM lParam)
{
 BOOL bRet = TRUE;
 if (IsWindowVisible(hwnd))
 {
  TCHAR szTitle[MAX_TITLE_LENGTH];
  GetWindowText(hwnd,szTitle,MAX_TITLE_LENGTH);
  CString strTitle = szTitle;
  if (strTitle.Find((LPCTSTR)global_strTitle) != -1)
  {
   hWndWindow = hwnd;
   bRet = FALSE;
  }
 }
 return bRet;
}

 

...
HWND CRemote::GeneralSearchWindow(LPCTSTR lpWindowName )
{
 global_strTitle = lpWindowName;
 EnumWindows((WNDENUMPROC)EnumWndProc,0);
 return hWndWindow;
}

...

//查詢代碼
CRemote objNotepad;
HWND hWndNotepad = objNotepad.GeneralSearchWindow(_T("遠程"));
