delegates in classes - Visual Basic .NET

Robert Batt

Hello,
I'm trying to modularize the code in my forms by
putting some procedures and delegates in a seperate class.
However I try to put a delegate with the following header
in a class.
Public Sub DecimalToCurren cyString(ByVal sender As
Object, ByVal cevent As ConvertEventArg s)
However I get a syntax error on ConvertEventArg s, saying
it is not declared. the class will not let me import
system.windows. forms for some reason.
Any ideas if or how I can get around this, or are
delegates just not allowed in classes

Regards
Robert

Robert,
Are you talking a Class or a Class Library?

As a Class within your current Project should not be causing your problems,
it sounds like you defined a new Class in a new Class Library.

Remember that Imports go outside the Class statement. If this new Class is
in a Class Library you need to reference (Project - Add References) the
assembly where the namespace is defined. Both the namespace & assembly for a
Class is defined in the Requirements section of the info topic on the class
in MSDN.

As far as where to define a delegate itself, it can be defined inside or
outside of a Class depending on your "requiremen ts".

Hope this helps
Jay

You need to declare a delegate like this.

Public Delegate Sub DecimalToCurren cyString(ByVal sender As Object, ByVal
cevent As ConvertEventArg s)

Delegates can be defined in namespaces... so there's no problem where you
can define them, however, you haven't correctly declared the delegate, you
need to use the "Delegate" clause...

Public Delegate Sub DecimalToCurren cyString(...)

thread-safe use of .NET events/delegates? How?

by: Steven Brown | last post by:

I'm trying to figure out how to safely use .NET events/delegates in a thread-safe class. There are a couple problems. One is that the standard "if(EventName != null) EventName(...);" call can fail if the event is emptied of all methods between the two statements, implying that some sort of synchronization between this and removals from EventName is needed. The other problem is that if an event with a set of delegates is in the process...

.Net Loophole? (by way of delegates)

by: Brad | last post by:

Question for all: Would one consider this a loophole in .net with respect to nested (inner) classes? 1) Create outer class Foo and create a nested class Yin (inside Foo's class definition ofcourse). 2) Let Foo have non-static protected (or public) method Bar() and Yin have a non-static method called Yang(). 4) Add a member object to Foo of Class Yin called yinObj.

Events vs. Delegates

by: Burkhard | last post by:

Hi, I am new to C# (with long year experience in C++) and I am a bit confused by the language construct of events. What is it I can do with events that I cannot do with delegates? At the moment it seems to me that Microsoft has developed similar functionality via two keywords. I do understand that an event offers better encapsulation as the underlying delegate is private, but is that all ? -- Regards

Delegates: When and why (besides events and threads)?

by: Jon Davis | last post by:

I've used delegates fairly heavily for several years in C# for event handling and for starting threads. Does anyone have any real-world scenarios where delegates were both extremely useful and extremely appropriate (as opposed to other programmatic means or mechanisms) that were NOT related to events and ThreadStarts? Thanks, Jon

How often do you use "delegates" (Events) over "interfaces" anyway?

by: raylopez99 | last post by:

I understand delegates (static and non-static) and I agree they are very useful, and that the "Forms" used in the Windows .NET API could not work without them. That said, I'm curious as to how many heavy duty pro programmers in this newsgroup have actually used a delegate in their code, say in the last year of coding. By "use" I mean constructed a delegate and using it in an Event Source class and an Event Receiver class. Interfaces...

Delegates are useful, and here is why (sample program)

by: raylopez99 | last post by:

They usually don't teach you in most textbooks I've seen that delegates can be used to call class methods from classes that are 'unaware' of the delegate, so long as the class has the same signature for the method (i.e., as below, int Square (int)). Here is an example to show that feature. Note class "UnAwareClass" has its methods Square and Cuber called by a class DelegateClass. This is because these methods in UnAwareClass have the...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
