MDI question

Posted on 2002-05-14
Last Modified: 2010-05-02

I am trying out my first MDI app and I have a question. In my main MDIForm, I am able to create multiple instances of a child form. Is there a way for me to iterate thru all of the child forms, regardless of how many are up? I want to be able to do this without keeping a static counter. Also, if anyone could point me to a good site that could enlighten me on the ins and outs of VB MDI's I would appreciate it.

   Dim I As Integer

    For I = 0 To Forms.Count - 1
       If TypeOf Forms(I) Is frmMyForm Then
           Forms(I).ZOrder 0
       End if    

Where frmMyform is the name of the from you are looking for. You might also do something like:

if Forms(I).caption = "ME" then

<<Is there a way for me to iterate thru all of the child forms, regardless
of how many are up?>> The way I do this is by using the forms collection.  I set the Tag property of all child forms to "child". For example I add a menu option under a Windows menu "Close all child windows".  The code looks like this:

Private Sub mnuWinCloseChild_Click()
Dim n as integer
On Error Resume Next
Do While n < Forms.Count
   If Forms(n).Tag = "child" Then
      Unload Forms(n)
      n = n + 1
   End If
End Sub

Hope this helps...

PS: The reason the loop is While < Forms.Count is that Forms(1) will always be the MDI parent...

jhamlett, you should accept or reject the "forced" answer by ventond.  If you leave this question sitting here "locked" few people will bother to look at it and give you further input...
