OpenFileDialog.AutoUpgradeEnabled在Vista或7下不起作用?

问题描述

如果我指定OpenFileDialog.AutoUpgradeEnabled = true，则程序仍显示旧的XP样式对话框.知道为什么会这样吗?这是在Main()中启用主题设置之后

If I specify OpenFileDialog.AutoUpgradeEnabled = true, my program still shows the old XP-style dialog. Any idea why this would happen? This is after I enable theming in Main()

[STAThread]
static void Main()
{
    Application.EnableVisualStyles();
    Application.Run(new Primary());
}

这是我的对话代码:

private void OpenProgramFile()
{
    OpenFileDialog programFileDialog = new OpenFileDialog();
    programFileDialog.Filter = "Program files (*.exe;*.lnk)|*.exe|All files (*.*)|*.*";
    programFileDialog.FilterIndex = 0;
    programFileDialog.Title = "Select program file";
    programFileDialog.AutoUpgradeEnabled = true;
    programFileDialog.ShowHelp = true;

    DialogResult fileResult = programFileDialog.ShowDialog();
    if (fileResult != DialogResult.OK)
        return false;

    programFileDialog.Dispose();
}

那为什么AutoUpgradeEnabled不起作用?

So why would AutoUpgradeEnabled not work?

推荐答案

避免设置programFileDialog.ShowHelp=true. ShowHelp属性与Vista/7文件对话框UI不兼容.打开的文件对话框仍将显示一个问号帮助图​​标.

Avoid setting programFileDialog.ShowHelp=true. The ShowHelp property is not compatible with the Vista/7 file dialog UI. The open file dialog will still show a question-mark help icon.
