[2005] Make a function wait for an event before returning value

[Latin4567]

I was putting the finishing touches on my widget engine and I encountered a rather annoying problem. My engine has a custom MsgBox function which overrides the framework's msgbox function once the engine has been imported into a solution. To make a long story short, my msgbox function shows a 'widget' object which is the size of a msgbox and has buttons, text.. etcetera... One of the defining features of a msgbox, is that it stops whatever is currently processing and waits for the user to click a button. Now normally I would just use the showdialog function on my widget and use a with statement to detect when the dialogresult value has been set. The problem is, showdialog messes up the parent/child relationships of my widgets so I am forced to use show(), which does not produce a value. Therefore I will have to somehow force my MsgBox function to wait for the OnClick event of one of its buttons BEFORE returning a value. How can I do this? Multi-Threading?

Is this for Yahoo widgets?

You could do many things, but that may lead to more complex solutions... maybe you should describe the parent child relationships.

no its for my own widget engine that I made.... child objects are actually popup windows so the showdialog function screws them up

basically i need to figure out how to block the calling thread and wait for a form to close before resuming (emulate the showdialog function)

i figured it out.... the startposition property of my main form was screwing things up... i just set it to manual and the children windows work with the showdialog function again

Public Class Form1
    Private SomeEventRaised As Boolean = False
    Private Sub SomeOperation()
        'code
        While SomeEventRaised <> True
        End While
        'The event was raised, go on
    End Sub
    Private Sub EventHandler(ByVal sender As Object, ByVal e As System.EventArgs) Handles SomeObject.Event
        SomeEventRaised = True
    End Sub
End Class
