CFileDialog
不是只能用来打开,保存一个文件吗,我想怎么选择到一个文件夹,不是文件Top

有一个现成的类可以，不过是非模式的对话框，有时候不适合的
CString m_strFolder;
if(g_fSelectFolderDlg(&m_strFolder,m_strFolder,false))
{
MessageBox(m_strFolder);
}
路径就在m_strFolder中，记得包含头文件 #include "global.h"Top

找不到 "global.h" 文件Top

利用CFileDialog类
如下
CString path;
CFileDialog dlg(TRUE,NULL,"*.*");
if (dlg.DoModal()==IDOK){//当你找到文件并确定打开时
path = dlg.GetPathName();
}Top

我想要的是一个能够选择文件夹的方法,就像安装一个程序时,你可以选择一个文件夹作为路径Top

当然是用SHBrowseForFolder
BROWSEINFO info;
memset(&info,0);
SHBrowseForFolder(info);
大概就是这个样子啦！Top
