Global form load event

apart from using a controlcollection in the main form and filling it up with all the forms of the project as i create them...or adding the load event in each form to a global load event as i create them...(using VB 2005 btw) is there any way to catch the application form load event...for ANY form that gets loaded?
I was hopping the application space had this event in it but it doesn't...so is there a magic fancy way of doing this in just one code without messing around with every form created?

Shorty...i'd like a global form_load event without putting any code into forms(apart from the main form if it's necessary)

Hi coyotee,

I think the best way is to create a custom and reusable form in which you can set an argument to interact with the main thread like this:

Public Class GlobalLoader

    Public Event evtNewForm(ByVal obj As Object)
   
Public Sub OnNewForm(ByVal obj As Object)
        RaiseEvent evtNewForm(obj)
        End Sub

End Class

The custom form:
Public Class CustomForm
    Inherits System.Windows.Forms.Form

gLoader As GlobalLoader
Sub New (ByVal obj As Object)
gLoader=CType(obj,GlobalLoader)
End Sub

Protected Sub CustomForm_Load(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles MyBase.Load
        gLoader.OnNewForm("MyFormName")
End Sub
End Class

Finally in main thread, you can register the evtNewForm event to catch when a new form is loading or initializing depending on where you place the gLoader.OnNewForm("MyFormName") in your custom form.

Hope this helps.
