在MFC编程中经常会需要用到选择目录和选择文件的界面,以下总结一下本人常用的这两种对话框的生成方法:
选择目录对话框
//选择目录按钮
void CDcPackerDlg::OnBnClickedDecgen()
{
char szPath[MAX_PATH]; //存放选择的目录路径
CString str;
ZeroMemory(szPath, sizeof(szPath));
BROWSEINFO bi;
bi.hwndOwner = m_hWnd;
bi.pidlRoot = NULL;
bi.pszDisplayName = szPath;
bi.lpszTitle = "请选择需要打包的目录:";
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))
{
str.Format("选择的目录为 %s", szPath);
AfxMessageBox(str);
}
else
AfxMessageBox("无效的目录,请重新选择");
}
void CDcPackerDlg::OnBnClickedDecgen()
{
char szPath[MAX_PATH]; //存放选择的目录路径
CString str;
ZeroMemory(szPath, sizeof(szPath));
BROWSEINFO bi;
bi.hwndOwner = m_hWnd;
bi.pidlRoot = NULL;
bi.pszDisplayName = szPath;
bi.lpszTitle = "请选择需要打包的目录:";
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))
{
str.Format("选择的目录为 %s", szPath);
AfxMessageBox(str);
}
else
AfxMessageBox("无效的目录,请重新选择");
}
选择文件对话框
CString CDcPackerDlg::BootOpenDialog() //返回选择的文件名称
{
CString strFile = _T("");
CFileDialog dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.cfg)|*.cfg|All Files (*.*)|*.*||"), NULL);
if (dlgFile.DoModal())
{
strFile = dlgFile.GetPathName();
}
return strFile;
}
//加载文件按钮
void CDcPackerDlg::OnBnClickedSelectdec()
{
// TODO: Add your control notification handler code here
m_strDescPath = ""; //类的成员变量
//"打开文件"对话框,选择文件,返回其路径
m_strDescPath = BootOpenDialog();
}
{
CString strFile = _T("");
CFileDialog dlgFile(TRUE, NULL, NULL, OFN_HIDEREADONLY, _T("Describe Files (*.cfg)|*.cfg|All Files (*.*)|*.*||"), NULL);
if (dlgFile.DoModal())
{
strFile = dlgFile.GetPathName();
}
return strFile;
}
//加载文件按钮
void CDcPackerDlg::OnBnClickedSelectdec()
{
// TODO: Add your control notification handler code here
m_strDescPath = ""; //类的成员变量
//"打开文件"对话框,选择文件,返回其路径
m_strDescPath = BootOpenDialog();
}
