最簡單的一個:
CString m_strFileName = "c:\\xyz.mdb";
CFileDialog fileDialog(TRUE, NULL, m_strFileName,OFN_HIDEREADONLY,"Access Files(*.mdb) and *.mdb and All Files(*.*) and *.* and and ");
if ( fileDialog.DoModal() == IDOK )
{
m_strFileName = fileDialog.GetPathName();
}

char lpszDisplayName[MAX_PATH], szFileName[MAX_PATH];
LPITEMIDLIST pidlDesktop, pidlCurrent;

if(SHGetSpecialFolderLocation(NULL, CSIDL_DESKTOP, &pidlDesktop)
== NOERROR)
{
BROWSEINFO bi;
bi.hwndOwner = this->m_hWnd;
bi.pidlRoot = pidlDesktop;
bi.pszDisplayName = lpszDisplayName;
bi.lpszTitle = "\n当前选择的邮局路径：";
bi.ulFlags = BIF_STATUSTEXT and BIF_RETURNONLYFSDIRS ;
bi.lpfn = BrowseProc;
bi.lParam = 0;
bi.iImage = 0;
pidlCurrent = SHBrowseForFolder(&bi);

SHGetPathFromIDList(pidlCurrent, szFileName);
m_strPostPath = szFileName;
}

CFileDialog dlg(......)
if(dlg.DoModal()==IDOK){
PathFile=dlg.GetPathName();
......
}

具体的，你可以使用CListView来派生一个目录选择的类：
在类的初始化代码中加入对目录的查找并生成对应的视图。
或者也可以用CTreeView,只要自己做个接口函数，完成
从目录到视图的转换就可以了！

Jackzhu,出不来。选择框没有出来。

[zjy]

char fname[MAX_PATH+1];
CFileDialog browse(TRUE,"*..*",fname,OFN_HIDEREADONLY and OFN_OVERWRITEPROMPT and OFN_NODEREFERENCELINKS and
OFN_ALLOWMULTISELECT and OFN_SELECTFOLDER);

browse.DoModal();
注意!第二行的第二个参数星号之间是两个点:"*..*"

[zjy]

对不起,
上述方法虽然可只列目录,但按OK钮对话框好象不能结束
我e-mail给你经过我改过的CFileDialog的派生类
告诉我你的e-mail

请快一点。

我忘了回掉函数了
int CALLBACK BrowseProc(HWND hwnd, UINT msg, LPARAM lParam, LPARAM lpData)
{
switch(msg)
{
case BFFM_INITIALIZED:
SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM)"c:\\");
break;
case BFFM_SELCHANGED:
{
char szFileName[MAX_PATH];
LPITEMIDLIST pidlCurrent = (LPITEMIDLIST)lParam;
SHGetPathFromIDList(pidlCurrent, szFileName);
SendMessage(hwnd, BFFM_SETSTATUSTEXT, 0, (LPARAM)szFileName);
}
break;
}
return 0;
}

// 设置邮局路径
void CSetupAdvanced::OnButtonBrowse()
{
char lpszDisplayName[MAX_PATH], szFileName[MAX_PATH];
LPITEMIDLIST pidlDesktop, pidlCurrent;

if(SHGetSpecialFolderLocation(NULL, CSIDL_DESKTOP, &pidlDesktop)
== NOERROR)
{
BROWSEINFO bi;
bi.hwndOwner = this->m_hWnd;
bi.pidlRoot = pidlDesktop;
bi.pszDisplayName = lpszDisplayName;
bi.lpszTitle = "\n当前选择的邮局路径：";
bi.ulFlags = BIF_STATUSTEXT and BIF_RETURNONLYFSDIRS ;
bi.lpfn = BrowseProc;
bi.lParam = 0;
bi.iImage = 0;
pidlCurrent = SHBrowseForFolder(&bi);

SHGetPathFromIDList(pidlCurrent, szFileName);
m_strPostPath = szFileName;
UpdateData(FALSE);
}

}

[deepwater]

BROWSEINFO bi;
bi.hwndOwner =m_hWnd;
bi.pidlRoot =NULL;
bi.pszDisplayName =pBuf;
bi.lpszTitle =pBuf;
bi.ulFlags =BIF_BROWSEFORCOMPUTER and BIF_RETURNONLYFSDIRS;
bi.lpfn =NULL;
bi.lParam =NULL;

LPITEMIDLIST pidl;
BOOL bSuccess=FALSE;

if(pidl=SHBrowseForFolder(&bi)){
if(::SHGetPathFromIDList(pidl,pBuf)){
if(pBuf[strlen(pBuf)-1]=='\\') pBuf[strlen(pBuf)-1]=0;
str.Format("%s\\%s",pBuf,pAttach->GetDisplayName());
bSuccess=CopyFile(pAttach->GetFileNameByRef(),str,TRUE);
}

[xiaozhe]

你这个程序你试过了吗？好使吗？？？？？其中的pBuf是什么东东？

[deepwater]

of course it's OK - it's from one of my projects

pBuf is a allocated buffer

[deepwater]

of course it's OK - it's from one of my projects

pBuf is a allocated buffer
m_hWnd is the handle of parent window

[xiaozhe]

到现在为止，我还没有一个答案是可以用的！！！

[xiaozhe]

谢谢Deepwater

Check your mail,I've sent u a demo

[Wingsun]
