%localappdata%

一般寫程式時會了將來除錯容易

通常會讓程式在執行過程中產生.log 檔案

若不想要讓end user看到這些檔案

我們可以將log產生在%localappdate%這個隱藏資料夾裡面
For example 實際路徑可能長這樣: // C:\Users\User name\AppData\Local\MyProgram\DOTNETFX.log

Sample code 如下:

CString dnetTagFilePath=getCurrentUserDirectory()+_T("\\DOTNETFX.log");   // C:\Users\User name\AppData\Local\MyProgram\DOTNETFX.log

定義getCurrentUserDirectory 並更改_stprintf (path, _T("%s\\MyProgram"), path);

CString CAppTools::getCurrentUserDirectory() {   CString szCurrentUserDirPath;   TCHAR path[MAX_PATH];   memset (path, 0, MAX_PATH*sizeof(TCHAR));   SHGetFolderPath (NULL, CSIDL_LOCAL_APPDATA, NULL, SHGFP_TYPE_CURRENT, path);   _stprintf (path, _T("%s\\MyProgram"), path);   ::CreateDirectoryW (path, NULL);   szCurrentUserDirPath.Format(_T("%s"), path);   return szCurrentUserDirPath; }
