Converting to VB from C# RaiseEvent problem???

Question

User1894305733 posted

Hi I have the following code:

 

1    Protected Overloads Overrides Sub OnInit(ByVal e As EventArgs)
2            MyBase.OnInit(e)
3    
4            Dim login As Login = TryCast(Control, Login)
5            If Extender.AdapterEnabled AndAlso (login IsNot Nothing) Then
6                RegisterScripts()
7                login.LoggingIn += OnLoggingIn()
8                login.LoggedIn += OnLoggedIn()
9                login.LoginError += OnLoginError()
10               _state = State.LoggingIn
11           End If
12       End Sub

 

I get errors on line 7, 8 and 9 stating that I should use RaiseEvent to obviously raise an event. I am stuck with this after searching google but I can find no real explanation of this in terms of the login control can anyone help? Or at least point me in the right direction?

Hi,

unlike C#, VB.NET doesn't use the += syntax to add an eventhandler. Instead you should write it like this:

AddHandler login.LogginIn, AddressOf OnLoggingIn

Hi thanks for the swift reply works now!

My code is:

 

1    Protected Overloads Overrides Sub OnInit(ByVal e As EventArgs)
2            MyBase.OnInit(e)
3    
4            Dim login As Login = TryCast(Control, Login)
5            If Extender.AdapterEnabled AndAlso (login IsNot Nothing) Then
6                RegisterScripts()
7                AddHandler login.LoggingIn, AddressOf OnLoggingIn
8                AddHandler login.LoggedIn, AddressOf OnLoggedIn
9                AddHandler login.LoginError, AddressOf OnLoginError
10               _state = State.LoggingIn
11           End If
12       End Sub

 

Again thanks! New to this VB stuff so learning all the time!
