TCHAR correct usage

[drwbns]

Hello, I'm trying to get a Browse Directory dialog to update a text box with the path selected. I had it working fine in Unicode build but now using TCHAR - I see the variable contains the correct path, but the textbox only gets updated with a single weird character. Any help would be great, thanks.

setting the text checking WM_COMMAND vars-

SetWindowText(textBox2,&buttonPush(hWnd));

browse function when Browse button is pressed -

TCHAR& buttonPush(HWND hWnd) {
		BROWSEINFO bi;
   TCHAR szDir[MAX_PATH];
   LPITEMIDLIST pidl;
   LPMALLOC pMalloc;

   if (SUCCEEDED(SHGetMalloc(&pMalloc)))
   {
      ZeroMemory(&bi,sizeof(bi));
      bi.hwndOwner = hWnd;
      bi.pszDisplayName = 0;
      bi.pidlRoot = 0;
      bi.ulFlags = BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT | BIF_USENEWUI | BIF_NONEWFOLDERBUTTON;
	  bi.pszDisplayName = szDir; // Address of a buffer to receive the display name of the folder selected by the user
		bi.lpszTitle = _T("Select a folder "); // Title of the dialog

      bi.lpfn = BrowseCallbackProc;
	pidl = SHBrowseForFolder(&bi); 
		
		if (pidl) 
		{ 
			// Folder selected in dialog
			TCHAR szReturnedDir[_MAX_PATH];

			BOOL bRet = ::SHGetPathFromIDList(pidl, szReturnedDir);
			if(bRet) return *szReturnedDir; // szReturnedDir holds the correct selected dir
			pMalloc->Free(pidl); 
		} 
		pMalloc->Release();
    }
   return *szDir;
}
