Question

Is there a possible way in VB.NET to disable the close button of the main form as I’ve seen in many installer! I don’t want to hide it, I want to completely disable it!

Thanks in advance

Since the blog post in the accepted answer has been taken offline, the following is a solution for C#.NET:

Using the C#.NET to VB.NET converter on DeveloperFusion, the equivalent VB.NET solution is:

Private Const CP_NOCLOSE_BUTTON As Integer = &H200
Protected Overrides ReadOnly Property CreateParams() As CreateParams
    Get
        Dim myCp As CreateParams = MyBase.CreateParams
        myCp.ClassStyle = myCp.ClassStyle Or CP_NOCLOSE_BUTTON
        Return myCp
    End Get
End Property
