Is there any Way I can use this to select the Directory This is the code I am using.It Allows me to select *.exe File When Choose EXE in Files of Type in File Open Dialog. but Not able to select the Directoy when Select FOLDER Option.

void FileOpenDlg(WCHAR *Path)
{
OPENFILENAME ofn;

	ofn.lStructSize = sizeof ( OPENFILENAME) ;
	ofn.hwndOwner = hDlg ;
	ofn.hInstance = NULL ;	//Not supported
	**ofn.lpstrFilter =\_T("Application (\*.Exe;\*.avi) \\0 \*.Exe;\*.avi\\0 FOLDER \\0 ") ;** 
	ofn.lpstrCustomFilter = NULL ;	//Not Supported
	ofn.nMaxCustFilter = 0 ;	//Not Supported
	ofn.nFilterIndex = 1 ;
	ofn.lpstrFile = Path ;		// Set in Open and Close functions
	ofn.nMaxFile = MAX\_PATH ;
	ofn.lpstrFileTitle = NULL ;	// buffer that receives the file name (without path information) 
	ofn.nMaxFileTitle = MAX\_PATH ;
	ofn.lpstrInitialDir = NULL;
	ofn.lpstrTitle = NULL ;
	ofn.Flags = 0 ; 	       // Set in Open and Close functions
	ofn.nFileOffset = 0 ;
	ofn.nFileExtension = 0 ;
	ofn.lpstrDefExt = NULL ;
	ofn.lCustData = 0L ;

Use the followign code:

CString YourClassName::GetFolderName()
{
BROWSEINFO br;

CString title = "Select the folder to convert its files";
char buff\[MAX\_PATH\];

br.hwndOwner = m\_hWnd;
br.pidlRoot = NULL;
br.lParam = NULL;
br.lpfn = NULL;
br.lpszTitle =( (LPTSTR) ((LPCTSTR)title));
br.pszDisplayName =(LPTSTR) buff;
//br.ulFlags = BIF\_BROWSEINCLUDEFILES;
br.ulFlags = BIF\_RETURNONLYFSDIRS;

LPITEMIDLIST item;
item = ::SHBrowseForFolder ( &br );
::SHGetPathFromIDList ( item, buff );

return buff;

}

Hoping that it will help you.

You need to release the memory allocated for item after you get the path name. As the documentation for SHBrowseForFolder says: The calling application is responsible for freeing the returned PIDL by using the Shell allocator's IMalloc::Free method. To retrieve a handle to that IMalloc interface, call SHGetMalloc.

LPMALLOC pMalloc;

SHGetMalloc (&pMalloc);
pMalloc->Free (item);
pMalloc->Release ();

Note my reply to the code that Anurag gave you. Also, prior to using that code, you must have called CoInitialize or CoInitializeEx. Judy
