MFC CFolderDialog example

MFC 기반 프로그램에서 파일 열기 대화창이 아닌 디렉토리 선택 대화창을 구현한 클래스 예제

사용법:

CFolderDialog dlg(AfxGetMainWnd());

if(dlg.DoModal() == IDOK)

{

CString dirPath = dlg.m_sPath;

AfxMessageBox(dirPath);

}

CFolderDialog.h

#pragma once

#include "afxdlgs.h"

class CFolderDialog : public CCommonDialog

{

public:

CFolderDialog(CWnd* pParentWnd);

CString m_sPath;

BROWSEINFO  m_bi;

static INT CALLBACK BrowseCallbackProc( IN HWND   hWnd, IN UINT   uMsg, IN LPARAM lParam, IN LPARAM lpData );

int DoModal();

};

CFolderDialog.cpp

#include "stdafx.h"

#include "CFolderDialog.h"

}
