Cannot Reference Parent variables from a MDI Child Form

[=?Utf-8?B?U2FuZHk=?=]

Hi everyone

Some help pls.

1. MDI Parent Form
Have a variable Public TestVariable As String = "AAA"

In the Load procedure TestVariable = "BBB"

2. MDI Child Form

Do a debug.print (TestVariable) and displays "AAA"

If I hold my cursor over TestVariable in the IDE it
displays "BBB"


I do not see how I can reference the current value in TestVariable of "BBB"
in my code

The real reason for this is that I am in 1 MDI child form and I want to
determine if another MDI Child form is active
I want to get the value MDIParentForm.M diChildren.Leng th so I can
manipulate the forms to determine if the form I am concerned with is not open.

When I reference MDIParentForm.M diChildren.Leng th from the MDI Child in the
coder it always shows 0 (Zero)
When I hold my cursor over MDIParentForm.M diChildren.Leng th in the IDE it
displays 3 which is the correct number of MDI Child forms that are open.

Totally confusing

thanks
sandy

RE: Cannot Reference Parent variables from a MDI Child Form

Sandy,

From the child form you need to reference variables in the mdiparent form
like this:

Dim frm As MDIParentForm

frm = Me.MdiParent

MsgBox(frm.Test Var)

Kerry,

thank you, thank you, thank you

This resolved my problem completely. I would have never figured this out
on my own.
