calling a function in another form

[Geoff Jones]

Hi

Could somebody give me an example of a way to call another member function
of another form from a form that has been called using ShowDialog?

Thanks

Geoff

Pass a reference to the form to your dialog before calling its 'ShowDialog'
method, for example, by assigning it to a property of the dialog.

In your dialog form:

\\\
Private m_ResultForm As MainForm

Public Property ResultForm() As MainForm
Get
Return m_ResultForm
End Get
Set(ByVal Value As MainForm)
m_ResultForm = Value
End Set
End Property
..
..
..
Me.ResultForm.L abel1.Text = "Hello World!"
///

In the main form:

\\\
Dim f As New DialogForm()
f.ResultForm = Me
f.ShowDialog()
f.Dispose()
///

Just as a matter of interest though, why doesn't this work:

'from within the dialog code
Me.Parent.funti onInCallingForm ()

where funtionInCallin gForm() is the function in the form where the dialog is
created. That is, as the parent of the dialog is that form, I thought this
might work - it doesn't :(

Can anybody explain why it doesn't work?

There is no parent-child relation between the form that shows the form and
the form that is shown modally.
