/*
如果想要在瀏覽資料夾的對話框開啟時，展開樹狀目錄在特定的資料夾上時，可做下列修改：
LPCTSTR lpszInitialPath = m_csPath;
bi.lpfn = BrowseCallBackProc;
bi.lParam = (LPARAM)lpszInitialPath; //預設的資料夾

然後再上面的OnBTGetPath()之前加上：
int CALLBACK BrowseCallBackProc(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData){
if (uMsg == BFFM_INITIALIZED && lpData != NULL) {
::SendMessage(hwnd, BFFM_SETSELECTION, true, lpData);
}
return 0;
}
