MFC我用DeleteFile为什么报错

[maninblack101]

代码如下：
void CFileCleanDlg::OnBnClickedButtonDelete()
{
CString path1, path2, path3;
path1 = "d:\\APP";
CFile Tempfile;
myDeleteDirectory(path1);
// TODO: 在此添加控件通知处理程序代码
}


void CFileCleanDlg::myDeleteDirectory(CString m_path)
{
CFileFind finder;
CString path;
path.Format("%s/*.*", path);
BOOL bWorking = finder.FindFile(path);
while (bWorking){
bWorking = finder.FindNextFile();
if (finder.IsDirectory() && !finder.IsDots()){//处理文件夹
myDeleteDirectory(finder.GetFilePath()); //递归删除文件夹
RemoveDirectory(finder.GetFilePath());
}
else{//处理文件
DeleteFile(finder.GetFilePath());
}
}
}

参考：

/**************************************************************************

   DeleteFolder()

**************************************************************************/

BOOL DeleteFolder(HWND hWnd, LPSTR lpszFolder)
{
char              szFile[MAX_PATH];
SHFILEOPSTRUCT    fos;
WIN32_FIND_DATA   FindData;
HANDLE            hFind;
BOOL              bFindFile = TRUE;

//we can't remove a directory that is not empty, so we need to empty this one

lstrcpy(szFile, lpszFolder);
lstrcat(szFile, "\\*.*");

ZeroMemory(&fos, sizeof(fos));
fos.hwnd = hWnd;
fos.wFunc = FO_DELETE;
fos.fFlags = FOF_SILENT | FOF_ALLOWUNDO;   //send to the recycle bin

hFind = FindFirstFile(szFile, &FindData);

while((INVALID_HANDLE_VALUE != hFind) && bFindFile)
   {
   if(*(FindData.cFileName) != '.')
      {
      //copy the path and file name to our temp buffer
      lstrcpy(szFile, lpszFolder);
      lstrcat(szFile, "\\");
      lstrcat(szFile, FindData.cFileName);
      //add a second NULL because SHFileOperation is looking for this
      lstrcat(szFile, "\0");

      //delete the file
      fos.pFrom = szFile;
      SHFileOperation(&fos);
      }

   //find the next file
   bFindFile = FindNextFile(hFind, &FindData);
   }

FindClose(hFind);   

return RemoveDirectory(lpszFolder);
}

先从最里面开始删除。同时查看一下出错时的返回错误码是什么

[syy64]

finder.GetFilePath()，看看里面的值是什么？

改了改

//
BOOL myDeleteDirectory(CString newPath)
{
	CString search=newPath;
	search +="\\*.*";
	CFileFind finder;
	BOOL bWorking = finder.FindFile(search);
	while (bWorking)
	{
		bWorking = finder.FindNextFile();
		if (finder.IsDirectory() && !finder.IsDots())
		{//处理文件夹  
			//afxDump << finder.GetFilePath() << "\n";
			myDeleteDirectory(finder.GetFilePath()); 
		}
		else
		{//处理文件  
			//afxDump << finder.GetFilePath() << "\n";
			DeleteFile(finder.GetFilePath());
		}
	}
	return RemoveDirectory(newPath);
}
// del a fold
void CxxxxDlg::OnButton4() 
{
	// TODO: Add your control notification handler code here
	CString root;
	root = "APP";
	BOOL ret=myDeleteDirectory(root);
	if(!ret) AfxMessageBox(root+"Delete Failed!");
}

另外这种 delete 不是放 垃圾箱， 很难恢复！

加断点看调试信息，应该就可以找到出错的那句了 看下参数值就知道了

[zgl7903]

path.Format( _T("%s\\*.*"), m_path); 把文件路径TRACE出来看看 GetLastError 看错误信息

[蠓虫带着秤砣飞]

同意楼上的，路径增加上\\*.*

单步调试看每条语句执行后的结果，就能发现问题了，代码是不会骗人的
