Checking for Instance of Form - RESOLVED

[stingrae]

hi,

i have a MdiParent form that creates a new instance of another form and it display and naturally it is an MDIChild. Really simple stuff.

the problem is that I have a timer on the MDIParent that does stuff (naturally ) and this causes problems with the MDIChild.

What I would like to do, is inside the MDIParent's Timer control, place a check in there to see "if this particular MDIChild form is open, then don't execute this".

is there a simple way to do this? (does this make sense?)

thanks all

You could examine the MDIChildren array of the parent form and see if your child form is in it...

Slow_Learner,

thanks - nice idea! i never thought of that.

in my mind, i know exactly what you mean - i.e. create a For loop and check the name etc...

but how do i code it? i can't find anything in help about MdiParent being an arry. is it a "For Each x in Y" or is it "For x - 0 to Parent.Count" style of loop?

are you able to paste the basic for...loop structure?


cheers

Ought to be something like

Dim frmFoo As Form
For Each frmFoo In frmParent.MDIChildren
    If frmFoo.Name = "Something" Then
        'Do some stuff
    End If
Next

Post if it gives you problems, I haven't actually tried this but it should work.

or you could set a flag if the child form is open...just dump this in the parent

Dim blnFound As Boolean = False
Dim frmChild As Form
    For Each frmChild In Me.MdiChildren
If TypeOf frmChild Is frmChoose Then
frmChild.Focus()
blnFound = True
   Exit For                     
End If

they both worked.

thanks guys!

Using TypeOf like EyeTalion suggests is probably much better than using .Name. Glad it's fixed!
