Re: How to remove parts of a string

Here is one way to do it. It assumes that the structure of the string remains the same all the time.

VB.NET Syntax (Toggle Plain Text)
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.IndexOf("str=")
        If StartPoint >= 0 Then
            StartPoint += 5
            Dim EndPoint = TextBox1.Text.IndexOf("/>", StartPoint)
            If EndPoint > StartPoint Then
                TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - 1 - StartPoint)
            End If
        End If
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.IndexOf("str=")
        If StartPoint >= 0 Then
            StartPoint += 5
            Dim EndPoint = TextBox1.Text.IndexOf("/>", StartPoint)
            If EndPoint > StartPoint Then
                TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - 1 - StartPoint)
            End If
        End If
    End Sub

Re: How to remove parts of a string

Another way. If your text is in a textbox then click between the "" marks and then press a button. as:

VB.NET Syntax (Toggle Plain Text)
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.LastIndexOf(Chr(34), TextBox1.SelectionStart) + 1
        Dim EndPoint As Integer = TextBox1.Text.IndexOf(Chr(34), TextBox1.SelectionStart)
        TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - StartPoint)
    End Sub
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim StartPoint As Integer = TextBox1.Text.LastIndexOf(Chr(34), TextBox1.SelectionStart) + 1
        Dim EndPoint As Integer = TextBox1.Text.IndexOf(Chr(34), TextBox1.SelectionStart)
        TextBox2.Text = TextBox1.Text.Substring(StartPoint, EndPoint - StartPoint)
    End Sub

Re: How to remove parts of a string

That looks like an 'attribute' within an xml file.

Therefore it would be sensible to use consider it as an xml object and use the methods associated with that.
