Introduction

File browsing in MFC is easy due to the included CFileDialog class. CFolderDlg wraps the SDK's SHBrowseForFolder function and makes folder browsing as easy as file browsing.

Features

The programmer can specify an initial folder. The user can create new folders. The dialog is resizable.

Using the code

You can get the name of a user selected folder in three lines of code:

// create and initialize a new object
CFolderDlg dlg(TRUE, m_folder, this);

// show dialog
if (dlg.DoModal() == IDCANCEL) return;

// get selected folder
m_folder = dlg.GetFolderName();

If you want to give some extra information to the user, you can add the following line:

// set the text that is displayed above the tree view control
dlg.SetTitle("Any instructions...");

The CFolderDlg constructor looks like this:

CFolderDlg(BOOL HideNewFolderButton, 
        const CString& InitialFolder, CWnd* pParent);

Points of Interest

If you are using Microsoft Visual C++ 6.0 (as I am), you will have to upgrade your Software Development Kit (SDK):

1. Download the ISO version.
2. Use DAEMON Tools to install the SDK.
3. Replace your include folders:

   out:

   1. ...\MICROSOFT VISUAL STUDIO\VC98\<any>

   in:

   1. ...\MICROSOFT PLATFORM SDK\INCLUDE
   2. ...\MICROSOFT PLATFORM SDK\INCLUDE\MFC
   3. ...\MICROSOFT PLATFORM SDK\INCLUDE\ATL
   4. ...\MICROSOFT PLATFORM SDK\INCLUDE\CRT

If your compiler can't find CoInitializeEx(), add #define _WIN32_DCOM to your stdafx.h.
