Manipulate a button on another form

Hello,

I am trying to change the properties of a button on form1 from form2. The button on form1 is a toolbar button. When it is pressed, I have it set to "ButtonToolbarNew.Enabled = False", to disable it. I want to be able to re-enable it when a different button on another form, form2, is pressed.

Thanks again!

You going to have to have a reference to the other form in order to do that.

Hi,

I had read through those posts and tried:

Code:

---

'on FormMain
'on this form, when ButtonToolbarNew is clicked it opens FormCardDesign and also sets ButtonToolbarNew to Enabled = False
    Private Sub ButtonToolbarNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonToolbarNew.Click
        Dim frm As New FormCardDesign()
        frm.MdiParent = Me
        frm.Show()
        ButtonToolbarNew.Enabled = False
    End Sub

'---------------------------------------------

'on FormCardDesign
'on this form, when ButtonCloseFormCardDesign is clicked it closes FormCardDesign and also sets ButtonToolbarNew to Enabled = True
    Private Sub ButtonCloseFormCardDesign_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonCloseFormCardDesign.Click
        Me.Close()
        Dim frm As New FormMain()
        frm.ButtonToolbarNew.Enabled = True
    End Sub

---

The problem is that nothing happens... ButtonCloseFormCardDesign is still set to Enabled = False. What am I missing?

By the way, FormCardDesign is a MdiChild with FormMain as its MdiParent if that makes a difference. Also, ButtonToolbarNew is not a true toolbar button, but just a regular form button.


Thanks,

Try this:

VB Code:

Private Sub ButtonToolbarNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonToolbarNew.Click
        Dim frm As New FormCardDesign()
        frm.MdiParent = Me
        frm.Show()
        ButtonToolbarNew.Enabled = False
    End Sub
 
 
 
    Private Sub ButtonCloseFormCardDesign_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonCloseFormCardDesign.Click
        Dim frm As FormMain 'Or what ever your main forms name is
        frm = Me.ParentForm
        frm.Button1.Enabled = True
        Me.Close()
    End Sub

Thanks so much! It works perfectly!

I added a frm.Dock = DockStyle.Top to ButtonToolbarNew_Click to make sure the form doesn't keep opening up one step lower and to the right on the screen each time it opens, and it looks great...

Thanks again!

Something you might also want to try out is to keep a permanent reference on the 2nd form to the main form. This way it's much easier to refer to the main form.

Code:

---

Private Sub ButtonToolbarNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonToolbarNew.Click
        Dim frm As New FormCardDesign()
        frm.MainForm = me 'in the second form declare a Dim MainForm as FormMain
        frm.Show()
        ButtonToolbarNew.Enabled = False
End Sub

Private Sub ButtonCloseFormCardDesign_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonCloseFormCardDesign.Click
        Me.MainForm.Button1.Enabled = True 'see how much less code you need to do here
        Me.Close()
End Sub
