        ' Initialize the XmlWriter.
        Dim XmlWrt As XmlWriter = XmlWriter.Create("C:\00temp\GoogleEarth_VaneTest.xml", settings)

        With XmlWrt

            ' Write the Xml declaration.
            .WriteStartDocument()

            ' Write a comment.

            .Close()

        End With

        MessageBox.Show("XML file saved successfully. In C:\00temp\")

请指南



一旦文本框值带空格，例如ben singh它可能会产生如上所述的错误。

Please Guide

once the textbox value is with space for example ben singh it may thows erros as mentioned above.

推荐答案

将所有空格转换为下划线字符：

Convert all spaces to underscore characters:

mystring = mystring.Replace(" ", "_");

如果您在处理用户输入时执行此操作并在演示文稿中将其反转，则用户甚至不会注意到差异！

If you do this whenever you are handling user input and reverse it on presentation back, the user won't even notice the difference!
