How to check the form is load or not???

[Gene]

As my purpose is to load one form at a time,
so I want to unload another form before loading the form.
But how to check which form is being load, so I can unload it first.

Hi Gene,

How do you load your form, are you closing it, are you disposing it?

So send some code how you "load it" there are a lot of possibilities.

Thx for the reply,
I simply use form1.show and form1.close ( I'm a new user)
The situation is:
Form1: IsMdiContainer = True,
and using a mainmenu for the user to choose which form they want to display.
one method i think of is to check the item chosen in the mainmenu,
but I don't know how to set it not check after check, the code is
Private Sub MenuItem2_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MenuItem2.Click
If MenuItem2.Checked = False Then
MDI1Show() 'function to show form1
MenuItem2.Checked = True
End If

If MenuItem2.Checked = True Then
MenuItem2.Checked = False
End If
End Sub

Hi Gene,

Normaly Armin Zingler does all MDI and sometimes Herfried echo's that.
(This is just for fun between the regulars)

I never used a MDI in VB.net but here is a link that probably answers your
question.

When you next time have a problem with a form, put with it MDI, that will
probably be opened by Armin Zingler and he can help you much better with it
than me.

If you not find it with that, message back, if I am still here tonight
(probably not to long) or tomorrow I will try to help you than.
