Hi,

I have a problem in a MDI-project.
I declared a variable MyVarAA in frmMain.frm (Public MyVarAA) in the General
Declaration section)

I need this variable in Form1, so in the Form_Load of this form I wrote:

MyVarBB = frmMain.MyVarAA

When trying to run the program I get the following error:

Run-time error 426 (only one MDI-form allowed).

The debug-information tells me:

frmMain.MyVarAA = <object variable or with block variable not set>

Acoording to the book I use (Using Visual Basic 6) is this the way to do it.
Error in the Book? Bug in VB? Something else?

Thanks,

Sjoerd

Dim frm as frmMDIMain

'-- Load an instance of the MDI form
set frm = New FrmMDIMain
frm.Show
'-- Causes another instance of the MDI to load
frmMDIMain.Caption = "Ooops"
'-- Does not cause another instance to load
frm.Caption = "Correct'

So I said "Do you want a game of Darts?", he said "OK then", I said
"Nearest to bull starts". He said "Baa", I said "Moo", he said
"You're closest".

Can't get your solution working. It gave me the idea to create a new
"normal" form (form2) and declare the variables on this form. Then load
form2 in form1 when form1 is loaded and showed. This solution works. Keep
wondering why declaring in frmMain generates the error.

First off I don't know why you want to do it this way BUT here's something to
look at...

In the MDIForm do:

Option Explicit
Public MyVarAA As MDIForm1 'Declare an Object Varible

Private Sub MDIForm_Load()
'Just declaring it is only half the process. Have to use the
'Set blah = blahblah to actually create the references..
Set MyVarAA = MDIForm1 'Set the references to This Form
End Sub

Then in Form1 (MDIChild form) do:

Option Explicit
Dim MyVarBB As MDIForm1 'Declare an Object Varible (early binding)

Private Sub Form_Load()
Set MyVarBB = MDIForm1.MyVarAA 'Set the References to that in MDIForm
'Now MyVarBB has all the references of MDIForm1
End Sub


Have a good day...

I forgot to mention the following::

In the MDI Child form you could also do:

Option Explicit
Dim MyVarBB As MDIForm1
Private Sub Form_Load()
Set MyVarBB = MDIForm1 'Not Using .MyVarAA it will be the same (kinda)
'In this case MyVarAA in the MDIForm is not needed at all...
MyVarBB.Command1.Visible = False
End Sub

Why a form ? This is what a module is meant for !

That's because it's not a solution. It's a demonstration of
the problem. The solution I leave to you
