VC++下怎样选择一个路径，是用OpenDialog对话框吗?

Answer 1

inline int CALLBACK BrowseCallbackProc(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData)
{
_TCHAR szDir[_MAX_PATH]; switch(uMsg)
{
case BFFM_INITIALIZED: // 初始化
break; case BFFM_SELCHANGED: // 路径改变
if( SHGetPathFromIDList( (LPITEMIDLIST)lParam, szDir ) )
SendMessage( hwnd, BFFM_SETSTATUSTEXT, 0, (LPARAM)szDir );
break;

default:
break;
}

return 0;
}void CDlgOptionCapture::OnPathOpen() 
{
// TODO: Add your control notification handler code here
_TCHAR pszDisplayName[MAX_PATH];
BROWSEINFO bi;
LPITEMIDLIST lpID; // 设置参数
bi.hwndOwner = GetSafeHwnd(); // Handle to the owner window
bi.pidlRoot = NULL; // Location of root folder
bi.pszDisplayName = pszDisplayName; // Folder name selected
bi.lpszTitle = _T("选择路径"); // Title name
bi.ulFlags = BIF_RETURNONLYFSDIRS | BIF_STATUSTEXT; // Option flags
bi.lpfn = BrowseCallbackProc; // Callback function
bi.lParam = 0; // LPARAM
bi.iImage = NULL; // Image selected lpID = SHBrowseForFolder( &bi );
if( lpID != NULL )
{
if( SHGetPathFromIDList( lpID, pszDisplayName ) )
{
m_strPath = pszDisplayName;
if( m_strPath[m_strPath.GetLength() - 1] != '\\' )
m_strPath += _T('\\');
UpdateData( FALSE );
}
}
}

BOOL CNetSniperView::BrowseFolder(CString &sFolderPath, CString sTitle)
{
BROWSEINFO bi;
char Buffer[_MAX_PATH];
//初始化入口参数
bi.hwndOwner=NULL;
bi.pidlRoot=NULL;
bi.pszDisplayName=Buffer;
bi.lpszTitle=sTitle;
bi.ulFlags=0;
bi.lpfn=NULL;
LPITEMIDLIST pIDList=SHBrowseForFolder(&bi);
//用户取消操作
if(!pIDList)
   return FALSE;
SHGetPathFromIDList(pIDList,Buffer);
sFolderPath = Buffer;
LPMALLOC lpMalloc;
if(FAILED(SHGetMalloc(&lpMalloc)))
   return false;
lpMalloc->Free(pIDList);
lpMalloc->Release(); return TRUE;
}
