Help with C# to VB.Net Conversion

[Daniel Jeffrey]

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(Completed, this,
EventArgs.Empty);


Class........

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


protected void FireAsync(Delegate dlg, params object[] pList)
{
if (dlg != null)
{
Target.BeginInvoke(dlg, pList);
}
}

end class



VB.Net calling Code

Public MustInherit Class GridData
Inherits AsyncUtilities.AsyncOperation

AddHandler mobjData.Completed, AddressOf DataLoad_Finished
AddHandler mobjData.Cancelled, AddressOf DataLoad_Cancelled
AddHandler mobjData.Failed, New
System.Threading.ThreadExceptionEventHandler(AddressOf DataLoad_Failed)

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

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

'Public Event Completed(sender As Object, e As System.EventArgs)' 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
CompletedEventHandler and the instance is called CompletedEvent. So, try
passing 'CompletedEvent', not 'Completed', if a Delegate is expected.
Untested.

thanks this worked.

Who ever said C# and VB.Net are "fundamentally" 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.

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.
