Find all directories in a directory

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:

Code:

---

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

Code:

---

//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?

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".

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 ?!
