Can't disable the button from executing .BAT

Question

Can anyone explain why my button keeps launching the associated .BAT file every time I click it, even though I have set it to disabled?

Private Sub TabPage3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabPage3.Click
    Dim RetBat3

    RetBat3 = Shell("c:\QUEEN ANNES REVENGE\SYSTEM\BAT\UNDO_1.bat", 1)

    Button5.Enabled = False

End Sub

Answer 1

Because that event handler is tied to TabPage3_Click ?

Its not clear what you're trying to do, but you launch the batch file when TabPage3 is clicked, then disable a button control.

You probably want to remove this TabPage3 click and put the handler on the button instead

You could try adding

if (Button5.Enabled)
{
    Button5.Enabled = False
    RetBat3 = Shell("c:\QUEEN ANNES REVENGE\SYSTEM\BAT\UNDO_1.bat", 1)
}

It feels wrong, but based on the little information you've provided it might fix your immediate issue.
