对话框====================================


打开文件对话框
void FileDlg::OpenFileDialog(){


CFileDialog dlg(TRUE, NULL, NULL,
           OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
           NULL);


    if(dlg.DoModal() == IDOK)
    {
          CString szFilename = dlg.GetPathName();


CFile f;
f.Open(szFilename,CFile::modeReadWrite);
char* buf = new char[f.GetLength() + 1];
buf[f.GetLength()] = 0;


f.Read(buf,f.GetLength());
f.Close();


CString s(buf);
GetDlgItem(IDC_EDIT1)->SetWindowTextW(s);
delete[] buf;

    }
}




打开目录对话框
void FileDlg::OpenDirDialog(){
CString strP =_T("选择目录");  
int length = 1024;


LPWSTR szPath = strP.GetBuffer(1024);


// do something with the string that pwsz points to.


strP.ReleaseBuffer();


    CString str;
    BROWSEINFO bi;   
    bi.hwndOwner = m_hWnd;   
    bi.pidlRoot = NULL;   
    bi.pszDisplayName = szPath;   
    bi.lpszTitle = _T("请选择要遍历的目录：");   
    bi.ulFlags = 0;   
    bi.lpfn = NULL;   
    bi.lParam = 0;   
    bi.iImage = 0;   
    //弹出选择目录对话框
    LPITEMIDLIST lp = SHBrowseForFolder(&bi);  


    if(lp && SHGetPathFromIDList(lp,szPath))   
    {
CTreeCtrl* m_Tree = (CTreeCtrl*)GetDlgItem(IDC_FILETREE);
设置样式
m_Tree->ModifyStyle(NULL,TVS_HASBUTTONS | TVS_HASLINES | TVS_LINESATROOT); 
HTREEITEM root = m_Tree->InsertItem(szPath,NULL,NULL);///root就是节点的标题

this->FindFiles(m_Tree,root,NULL,szPath,0);
    }
else {
        AfxMessageBox(_T("无效的目录，请重新选择"));  

}
}
