Form won't close [nay bother]

[SjR]

My form won't close - the 'closing' and 'closed' events are not firing when I click on the 'X'

I've isolated this piece of code as the culprit... activated when you double click on a listview item.

Private Sub lvwFolderList_ItemActivate(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lvwFolderList.ItemActivate
 
        Dim ndParentnode As clsTreeNode = CType(Me.ParentForm.Controls(2), TreeView).SelectedNode
        Dim lv As ListView = CType(sender, ListView)
        Dim tvw As TreeView = CType(Me.ParentForm.Controls(2), TreeView)
 
        tvw.SelectedNode = ndParentnode.Nodes(lv.FocusedItem.Index)
 
End Sub

The list view is part of a user control that I've created which is added to a panel in the main form that I'm trying to close. The referenced TreeView is on the main form.

Anyone see what I'm missing?
Thanks in advance for any help.

The code you posted seems to have nothing to do with closing your main form or any form for that matter.
Forms generally don't close because you have another form open.
Make sure that all your forms are in a collection so you can see what you have current at any one time.

I agree that it doesn't seem to have anything to do with it.... but if this piece of code is commented out, the form will close fine. The project only contains 1 form, so it can't be because another is open... I'm confused

[cim3]

can you post any more code??

Look at what I've found :
Find out what's closing your application

Now , I guess you know why your app. is closing.

Someone in GotDotNet forums answered to the same question that I asked, and I posted that in codeproject.com so people like you could see it, because I thought it's very helpful. But some people said I was trying to "steal" code and take credit for it. Stupid

I put a message box in the closing and closed events of the form, but the msgbox was not showing when I clicked on the X on the form. This says to me that these events are not being triggered at all. Thanks for the link though - may prove useful in future

This is the controls load event

Private Sub ctrlFolderList_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
        Dim ndParentnode As clsTreeNode = CType(Me.ParentForm.Controls(2), TreeView).SelectedNode
        Dim ndNode As clsTreeNode
        Dim lv As ListView = CType(Me.Controls(0), ListView)
 
        For Each ndNode In ndParentnode.Nodes
            lv.Items.Add(ndNode.Text, ndNode.ImageIndex)
        Next
 
End Sub

Though the main form will still close if the control is loaded... its only when the items are activated that the form refuses to go away.

This happens with dialog forms during load event, that is you can not close it despite closing event fired! You said you have only one form in your application but this:

CType(Me.ParentForm.Controls(2), TreeView).SelectedNode

tells me there is a parent form in your project too. Am i wrong?

[SjR]

'Me' refers to the usercontrol "ctrlFolderList" and 'parentform' refers to the form that the control has been added to - the only form in the project.

Polite ,what do you mean exactly ?

[SjR]

I've had to change the way this user control is used, which means the coding has changed, and so I no longer have this problem!

I hereby re-classify this thread as "no longer requiring a resolution even though I don't know the answer" or "nay bother" for short.
