VB.NET Me.Close() doesn't work, the form doesn't close? - vb.net

Question

The form is an About Us form so has nothing on it only a text box and a OK button.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Me.Close()
End Sub
Here is how I'm opening the form:
Private Sub AboutAppStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AboutAppStripMenuItem.Click
Dim formAbout As New FormAbout()
formAbout.Show()
End Sub
Why won't the button close the form? I'm puzzled, I tried another button just in case with the same result.
UPDATE: I set a break point on Me.Close() and it isn't reaching it when I click the button, I created a new button and the same thing happened.
Thanks

Answer 1

I am betting the event handler for the button1_click event has been inadvertently removed.
Try double-clicking on the button in design time and see if it pulls you back to that same exact piece of code - or a new event handler definition.
If it's a new event handler definition - copy your code there and delete the first one.
There are other ways to manually add the event handler in the designer's code-behind - but maybe that's for a later progression.
From within VS click the "Show all files" button in solutions explorer. Grab us the code in .Designer.vb and paste it in here and we'll nail it down for you definitively.
Here's mine:
Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _
Partial Class Form1
Inherits System.Windows.Forms.Form
'Form overrides dispose to clean up the component list.
_
Protected Overrides Sub Dispose(ByVal disposing As Boolean)
Try
If disposing AndAlso components IsNot Nothing Then
components.Dispose()
End If
Finally
MyBase.Dispose(disposing)
End Try
End Sub
'Required by the Windows Form Designer
Private components As System.ComponentModel.IContainer
'NOTE: The following procedure is required by the Windows Form Designer
'It can be modified using the Windows Form Designer.
'Do not modify it using the code editor.
_
Private Sub InitializeComponent()
Me.Button1 = New System.Windows.Forms.Button
Me.SuspendLayout()
'
'Button1
'
Me.Button1.Location = New System.Drawing.Point(131, 91)
Me.Button1.Name = "Button1"
Me.Button1.Size = New System.Drawing.Size(133, 50)
Me.Button1.TabIndex = 0
Me.Button1.Text = "Button1"
Me.Button1.UseVisualStyleBackColor = True
'
'Form1
'
Me.AutoScaleDimensions = New System.Drawing.SizeF(6.0!, 13.0!)
Me.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font
Me.ClientSize = New System.Drawing.Size(292, 266)
Me.Controls.Add(Me.Button1)
Me.Name = "Form1"
Me.Text = "Form1"
Me.ResumeLayout(False)
End Sub
Friend WithEvents Button1 As System.Windows.Forms.Button
End Class

Answer 2

From MSDN:
Showing the control is equivalent to setting the Visible property to true. After the Show method is called, the Visible property returns a value of true until the Hide method is called.

Answer 4

I tested the following
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click
Dim f As New Form2
f.Show()
End Sub
End Class
Public Class Form2
Private Sub Button1_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) _
Handles Button1.Click
Me.Close()
End Sub
End Class
and did not have problems. As was suggested, re-create your button and code.

Add you Button Dynamically may solve the problem.
Place the following code in the load event of about Form.

Dim btn as new Button()
AddHandler btn.Click ,AddressOf _ClickToClose
End Sub
Private Sub _ClickToClose(ByVal sender as object,ByVal e as System.EventArgs)
Me.Close()
End Sub
