SetFocus

[sethindeed]

I have an MDIForm and some child forms.
I already wrote a routine that prevent a form from opening two times.
What I want to do next is that when the user tries to open an already opened form, I want this form to be in focus.
I used to do it quite easily in VB6 with the SetFocus method but this method is gone in .NET.
Anybody knows how can I do what I want ?
thx !

You can use a For Each to cycle through all open MDIForms and check
to see if it's an instance of the particular form using (I think) the TypeOf
operator (If TypeOf theForm Is Form2 Then theForm.Focus(), or
something similar).

Yes.
I already did it.
My question was related to bring an already opened form up front.
Sorry if I wasn't clear enough

Actually, I have some difficulties with the For Each syntax.

For each frm in Forms does not work

For each frm in System.Windows.Forms does not work neither

There is no more Forms collection in .NET, you'll have to create your own if you want this feature. An MDI form does keep track of it's children. You can use:

foreach(Form f in this.MdiChildren)
{
    // Use f.Show() or whatever you need...
}
