c++ builder 查询一个文件在本地的的完整路径,该如何处理

c++ builder 查询一个文件在本地的的完整路径
给一文件的文件名，通过代码查询该文件在本地，也就是电脑盘符中的完整路径，请高人指点，贡献出源码，不胜感激...

[解决办法]
这里抄了别人的一段代码，你看看：

C/C++ code

WIN32_FIND_DATA FileData; HANDLE hSearch; DWORD dwAttrs; char szDirPath[] = "c:\\TEXTRO\\"; char szNewPath[MAX_PATH]; char szHome[MAX_PATH];  BOOL fFinished = FALSE;  // Create a new directory.  if (!CreateDirectory(szDirPath, NULL)) {     ErrorHandler("Couldn't create new directory."); }  // Start searching for .TXT files in the current directory.  hSearch = FindFirstFile("*.txt", &FileData); if (hSearch == INVALID_HANDLE_VALUE) {     ErrorHandler("No .TXT files found."); }  // Copy each .TXT file to the new directory // and change it to read only, if not already.  while (!fFinished) {     lstrcpy(szNewPath, szDirPath);     lstrcat(szNewPath, FileData.cFileName);     if (CopyFile(FileData.cFileName, szNewPath, FALSE))    {         dwAttrs = GetFileAttributes(FileData.cFileName);         if (!(dwAttrs & FILE_ATTRIBUTE_READONLY))         {             SetFileAttributes(szNewPath,                 dwAttrs | FILE_ATTRIBUTE_READONLY);         }     }     else     {         ErrorHandler("Couldn't copy file.");     }      if (!FindNextFile(hSearch, &FileData))     {        if (GetLastError() == ERROR_NO_MORE_FILES)         {             MessageBox(hwnd, "No more .TXT files.",                 "Search completed.", MB_OK);             fFinished = TRUE;         }         else         {             ErrorHandler("Couldn't find next file.");         }     }}  // Close the search handle.  if (!FindClose(hSearch)) {     ErrorHandler("Couldn't close search handle."); }
