Program doesnt close

**SomethinCool** · Apr 7th, 2003, 09:11 PM

When i click the X on my program..the program doesnt close even though it should..why does it do that (i dont want to post all of the code...there isnt much anyway...)?

Also..in VB6 i was able to click on the combomenu at the top and choose Form1 and then the combomenu to the right i was able to choose Unload..so it would make a Private Sub Form1_Unload for me..why cant i do that in vb.net?

^ It does, you have changed something in your code. No idea until you paste some of it.

Also..in VB6 i was able to click on the combomenu at the top and choose Form1 and then the combomenu to the right i was able to choose Unload..so it would make a Private Sub Form1_Unload for me..why cant i do that in vb.net?

^ You can, you drop down the left box and choose Base Class Events, then click the right box and et voila. By the way, there is no such event as Unload, its now called Closing.

        'This call is required by the Windows Form Designer.
        InitializeComponent()
 
        'Add any initialization after the InitializeComponent() call
 
    End Sub
 
    'Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
        If disposing Then
            If Not (components Is Nothing) Then
                components.Dispose()

and the Module Code..

VB Code:

Module Module1
    Public frm1 As New Form1()
    Public frm2 As New Form2()
    Public frm4 As New Form4()
    Public Declare Function GetTickCount Lib "kernel32" () As Long
    Public Sub Pause(ByVal Interval As Long)
        Dim Start
        Start = GetTickCount
        Do While GetTickCount < Start + Interval
            Application.DoEvents()
        Loop
    End Sub
End Module

Open new project , paste your controls , functions and subs from the old proj to the new one .

**Grimfort** · Apr 8th, 2003, 02:10 PM

Change your END function to Close.

**Pirate** · Apr 8th, 2003, 02:14 PM

Where do you see that ?

**Grimfort** · Apr 8th, 2003, 02:44 PM

#Region " Menu Functions "
Private Sub MenuItem6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItem6.Click
End
End Sub
#End Region
#End Region
End Class

**Pirate** · Apr 8th, 2003, 02:57 PM

But that still works .
You can use: Application.Exit()

The problem may be with your ListView. You need to set focus off of the ListView before any changes are made to it (in your ListView1 click event that you have posted). This is a bug that for whatever reason, disables the close(x). I ran into this using a TreeView.

Not sure if it is the same with the ListView - but it might be worth a shot - and might save some time.

that happens to ALL controls..there was some posts made some time ago talking about known .NET bugs and that is one of that..if u do a search over here u'll probably find it

You may also want to look into removing the creation of instances of your forms until you need them. In your module you create an instance of all of your forms, which are then in a hidden state until you show them or close them. That may have an effect on closing your program, because you still have forms in memory.
