Event handling differences between C# & VB.NET

NET gurus... How would you convert this very chunk into VB?

this.timer = ne开发者_如何学运维w System.Timers.Timer(100);
this.timer.Elapsed+=new System.Timers.ElapsedEventHandler(ManageThreads);
this.timer.Start();

When I use an online converter (Telerik), the middle line converts like this:

Me.timer.Elapsed += New System.Timers.ElapsedEventHandler(ManageThreads)

with 2 errors: 1- "Public eventElapsed is an event and cannot be called directly. Use raiseEvent 2- Delegate requires an Adess Of expression. Do I simply add "Address Of" ?

Any clue warmly welcome.

The syntax for adding event handlers is very different between C# and VB.NET and as you've discovered Telerik doesn't handle that difference very well.

C# add handler syntax:

<object>.<event> += <event_handler_function>

VB add handler syntax:

add handler <object>.<event>, addressof <event_handler_function>

There is another catch you might run into with VB event handling: The object you're adding an event handler for has to be declared at class-scope. E.g. you cannot add a handler to a locally-created object (within a method) and return it or add it to a collection. So you basically have a class-level temp variable when you need to do things dynamically.

Good luck.

something strange returns this converter

Try: AddHandler Me.timer.Elapsed, AddressOf ManageThreads
