Using VS2005, VB.NET,
I am developing a windows app. The application opens a couple of
forms. While the forms are open I want to raise some events, such as
logging errors - but I call RaiseEvent, nothing happens. Below are
some code snippets that show what I am doing. Can someone straighten
me out... I feel like this must be something real simple...

'------------------------------------------------------------------------------
           Public Class frmMain
'In my main form, I declare my form with events so I can handle them
later...
                       Private WithEvents frmLogin As frmDomainLogin

                       Private Sub btnTest_Click(ByVal sender As
System.Object, ByVal e As System.EventArgs) Handles btnTest.Click
'In my main form, I create a new instance of another form, then open
it.
                                   frmLogin = New frmDomainLogin(Me)
                                   frmLogin.ShowDialog(Me) 'Wait here
till the form closes...
                       End Sub

                       Private Sub frmErrLog_LogError(ByVal strMethod
As String, ByVal strMessage As String) Handles frmErrLog.LogError
'In my main form, I want to catch the events raised from the other
form... but this code never gets executed... why not?
                                   Msgbox("Logging error:" &
vbnewline & strMethod & vbnewline & strMessage)
                       End Sub
           End Class
'------------------------------------------------------------------------------

'------------------------------------------------------------------------------
           Public Class frmDomainLogin
'So, here I declare my event, for use later...
                       Public Event LogError(someParameter as Object)

                       Private Sub frmDomainLogin_Load(ByVal sender
As Object, ByVal e As System.EventArgs) Handles Me.Load
                                   RaiseEvent LogError(Now & "
raising test event...")
                       End Sub

           End Class

hzgt9b,

I tried re-creating your scenario in a simple example and I did not have any
problems raising an event in a form being shown modally and handling the
event in the parent form.

Perhaps something else in your application is complicating the situation.

I have had problems with the same thing. Code that worked for the last 12
months suddently stopped responding to a raised event. I suspect that given
certain very bizarre conditions, VB.Net is causing this. Sadly, I was never
able to find the answer. Other events continue to work fine.
I resolved the problem by using binding rather than raise an event of my
own...Not much of an answer, but days of trying different things, including
deleting and rewriting a class, proved futile.

Just to show you are not alone with this problem, try a Google on "VB.Net +
RaiseEvent not firing"
