Mouse Events RRS feed

  • Question

  • I'm starting to learn how to do mouse events in vb.net and the first place I looked on msdn had a bit of code to get me rolling. Problem is I copy and pasted the code and get a three errors that I don't understand. It seems as though I'm missing a library or something I don't know where to start any help would be appreciated.

    "Load" cannot be found

    "TextBox1" is not declared

    "System.MouseEventArgs" is not defined

    Public Class Module1

        Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
            TextBox1.ContextMenu = New ContextMenu()
        End Sub
        Private Sub TextBox1_MouseDown(ByVal sender As Object, ByVal e As System.MouseEventArgs) Handles_   TextBox1.MouseDown
            If (e.Button = Windows.Forms.MouseButtons.Right) Then
                TextBox1.Select(0, TextBox1.Text.Length)
            End If
        End Sub
    End Class

    I'm guessing the TextBox1 is just a text box that I need to define somewhere but the other two problems I'm not sure of.

    Thanks in advance

  • Hi VBnoob101,

    I create a demo and reproduce your issue on my side, open the Form1.vb[Design] and drag textbox control to the design.

    Then click Form1 -> event -> select load -> select load method.

    The same as TextBox1.MouseDown Method.

    Best regards,
