Find all directories in a directory

[Raute50]

hi all,

i did not find any answer to my following question: how can i find all directories which are inside a specified directory using the MFC.

I wanted to use a similar approach to finding a file inside a directory but i did not find an analogon to FindFile.
Sounds strange, but i hope you will understand me!

Does anybody know how i can realize this ?!

You keep using FindFile, it also returns directories. Use CFindFile::IsDirectory to check if the returned file is actually a directory.

i tried to but it did not work ?!

my code for finding files looks like this:

void CMyDlg::OnButton1() 
{
	 WIN32_FIND_DATA FindFileData;
	 HANDLE hFind;
	 CString argv = "C:\\MyDirectory\\Textfiles\\*.txt";
	 hFind = FindFirstFile(argv, &FindFileData);
	 if (hFind == INVALID_HANDLE_VALUE) 
   {
		 if (ERROR_FILE_NOT_FOUND == GetLastError())
			 MessageBox("ERROR_FILE_NOT_FOUND");
   } 
	 else
		 {
		 // List all the files in the directory with some info about them.
		 LARGE_INTEGER filesize;
			 CString files = "found these files : \n";
		 do
		 {
				if (!(FindFileData.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
				{
					files += FindFileData.cFileName;
					files += "\n";
				}
		 }
		 while (FindNextFile(hFind, &FindFileData) != 0);
		 MessageBox(files);

		 DWORD dwError=0;
		 dwError = GetLastError();
		 if (dwError == ERROR_NO_MORE_FILES) 
		 { MessageBox("ERROR_NO_MORE_FILES"); }
	 }
}

this does already work for finding txt files!!!


i tried to change the CString argv to "C:\\MyDirectory\\Textfiles\\*" or "C:\\MyDirectory\\Textfiles\\*\\"; but both did not work.
with other things i tried i got errors.

can you tell me more explicitly how i have to manage this ?!

Well,If what you want is to find files in a directory u could do something like

//assign Pathname variable with the full path name
		//*.log = delete all files that has the .log extension or you could put filename.* to find all the files with that name no matter the extension
		CString PathName = "C:\\WINDOWS\\*.log";

		//Find the file Info
		hnd = FindFirstFile((LPCSTR) PathName,&info);

		//Start the loop
		do
		{

		//Assign csFile with Full path
		CString csFile = "C:\\WINDOWS\\";

		//here you can get the files name,size,creating time,attributes,acces time,etc.
		csFile += info.cFileName;

		//You can delete,move,copy,rename,write,read or what ever you want.
		DeleteFile(csFile);
		}

		//While findnextfile keep asking for findnextfile keep looping
		while( FindNextFile(hnd, &info) );

		//Close file search
		FindClose(hnd);

Hope that helped if that's what u where looking for.

no ... it doesn't help anyway ... because i already know how to find files .... i want to know how i find directories.

Thats why i chose the title of this thread!

Well,Can you post the errors that its giving you?

[Raute50]

the only other way i tried to was "C:\\MyDirectory\\Textfiles\\*\";

error C2001: newline in constant
error C2146: syntax error : missing ';' before identifier 'hFind'


but as i wrote down i understood the error ...


any hints ?!

solving my own problem:

i used WIN32_FIND_DATA FindFileData; in my code, which has to be replaced by CFileFind FindFileData; !!!
Afer some more changes and with the right use of FindFileData.IsDirectory() everything works correctly!

Thanks for all answers ...

Define "not work".

[Raute50]

one of them caused the following MessageBox
MessageBox("ERROR_FILE_NOT_FOUND");

the other caused a MessageBox where the only entry was:
found these files : \n

i did not remember which case of "...\\?" caused which MessageBox ?



hope i could help you ?!
