Reference to a Form stored in a Public Property
Experts,
I have a Main form called Designer. The Designer has a StatusBar. The Designer also has two panels (Panel1 and Panel2). Each Panel has a Form to show. I have decided that there is no need to have multiple StatusBars, only the one on the Designer.
On the Form opened in Panel1 I store the StatusBar values in an ArrayList. I want to pass this ArrayList to the Parent Designer Form Public Sub that updates the StatusBar.
So to update the StatusBar on the Designer I need a reference to the Designer form. Could I use a Public Property defined as Object or Variant? Would/Could I assign the value of the Public Property just after I create it?
Example:
Dim frm as new FormA
frm.p_FormInstance = frm
Then I could do something like:
call p_FormInstance.subUpdateSt
aList is the list of two settings for the StatusBar to update.

Take a look at "my.forms...." you can usually reference your forms directly using that.
Is "Designer" the MAIN form that the application STARTS with? Is it also the value set as the "Startup Object" in Project --> Properties?
If yes to both, then you can simply reference the Designer "BY NAME" as the default instance is what is displayed.
So, from within FormA, you can simply do:
Designer.subUpdateStatusBa
If yes to both, then you can simply reference the Designer "BY NAME" as the default instance is what is displayed.
So, from within FormA, you can simply do:
Designer.subUpdateStatusBa

JamesBurger,
Using DirectCast with your example worked like a charm. I have one question though...
I have the following code:
Private Sub subUpdateFormPanel()
Dim f_PanelForm As New frmDataGridViewProject_Edi
f_PanelForm.TopLevel = False
f_PanelForm.Parent = Me
f_PanelForm.p_sFormRecordE
f_PanelForm.p_fParentForm = Me.ParentForm
Panel_Form.Controls.Add(f_
f_PanelForm.Show()
End Sub
Which defines the Form I am opening in the Panel. The Editor form calls the StatusBar Subroutine to update the StatusBar on the Designer Main Form (which is not the MIDI container, but just another form in the application):
Call DirectCast(Me.Parent.Paren
Worked, but if I want to refer to more subroutines on the Designer form should I store this reference in one variable as the form is opened? Once the form closes the variable goes away.
So I thought I could do something like:
Dim objName as new Object
objName = Me.Parent.Parent.Parent.Pa

Did my comments not apply to your situation?...
