    Help with C# to VB.Net Conversion

    Hello,
    I am a C# developer and am now starting to do some work in VB.NET and for
    the life of me cant get something working the way I cant.

    If anyone can offer any suggestions on how to convert this c# into Working
    VB.Net code that would be great.

    C# Class to be converted to VB.Net

    I cant seem to get this line to work FireAsync(Compl eted, this,
    EventArgs.Empty );


    Class........

    public event EventHandler Completed;
    ...
    ...
    ...
    private void someMethod()
    {
    FireAsync(Compl eted, this, EventArgs.Empty );
    }


    protected void FireAsync(Deleg ate dlg, params object[] pList)
    {
    if (dlg != null)
    {
    Target.BeginInv oke(dlg, pList);
    }
    }

    end class



    VB.Net calling Code

    Public MustInherit Class GridData
    Inherits AsyncUtilities. AsyncOperation

    AddHandler mobjData.Comple ted, AddressOf DataLoad_Finish ed
    AddHandler mobjData.Cancel led, AddressOf DataLoad_Cancel led
    AddHandler mobjData.Failed , New
    System.Threadin g.ThreadExcepti onEventHandler( AddressOf DataLoad_Failed )

          This produces the same result I got when I did it myself

          'Public Event Completed(sende r As Object, e As System.EventArg s)' is an
          event, and cannot be called directly. Use a 'RaiseEvent' statement to raise
          an event.

              VB does something under the hood. The implicitly declared delegate is called

              passing 'CompletedEvent ', not 'Completed', if a Delegate is expected.

                  thanks this worked.

                  Who ever said C# and VB.Net are "fundamenta lly" the same, never moved from 1
                  to the other

                      Daniel,

                      You are translating code not converting.

                      In VB.Net there is the easy keyword WithEvents, try that as you convert,
                      instead of difficult ways as it has to be done in C# which can be easily
                      done in VB for Net.

                      WithEvents - Visual Basic
                      http://msdn.microsoft.com/en-us/library/aty3352y.aspx
                      Learn more about: WithEvents (Visual Basic)

                          Yea. I found problems with that converter now that I looked at it. I
                          converted some base classes for custom providers and it broke the code.
