Translating Delegate Usage From C# To VB
Apr 1, 2010
In physics library written in C# I have the following code:
[Code]...
I'd like to do the same in VB. (just thandling the delegate, not the declaration) I tried this, but it doesn't work: AddHandler ContactManager.PostSolve, AddressOf PostSolve The following works, but only allows me to have one handler for the delegate: ContactManager.PostSolve = new PostSolveDelegate(AddressOf PostSolve) Is there a way for me to do the same thing in VB that was done in the first piece of code?

from the documentation we have this: Multicast Delegate: Represents a multicast delegate; that is, a delegate that can have more than one element in its invocation list.
so am i right to say that Multicast delegate is no different from a normal delegate other than the fact that it has arguments. so System.Action is a 'normal' delegate whereas System.Action(T)(Byval obj as T) is a multicast delegate?

I get a error" Method 'Private Shared Sub Ping(item As BlogEngine.Core.IPublishable, itemUrl As System.Uri)' does not have a signature compatible with delegate 'Delegate Sub WaitCallback(state As Object)'.

I am trying to write a VB.NET alternative to a C# anonymous function.I wish to call Threading.SynchronizationContext.Current.Send which expects a delegate of type Threading.SendOrPostCallback to be passed to it. The background is here, but because I wish to both pass in a string to MessageBox.Show and also capture the DialogResult I need to define another delegate within. I am struggling with the VB.NET syntax, both from the traditional delegate style, and lambda functions.My go at the traditional syntax is below, but I have gut feeling it should be much simpler than this:
Private Sub CollectMesssageBoxResultFromUserAsDelegate(ByVal messageToShow As String, ByRef wasCanceled As Boolean)
wasCanceled = False

I'm trying to write a simple/small Windows Communication Foundation service application in Visual Basic (but I am very novice in VB) and all the good examples I've found on the net are written in C#. So far I've gotten my WCF service application working but now I'm trying to add callback functionality and the program has gotten more complicated. In the C# example code I understand how everything works but I am having trouble translating into VB the portion of code that uses a delegate. Can someone please show the VB equivalent?
Here is the C# code sample I'm using for reference:
[code...]
Is that casting the callback object as type ICommunicationObject? How is that done in VB?

I have to admit, I can't always translate C# code to VB. Case in point:the MSDN library has the definition and example of an FTPWebRequest in C#, but not in VB. I think I can understand most of it, but can someone translate the small snippet below for me? Don't worry about the variable definitions, I've got that, but I can't tell of the subsequent methods are functions or sub routines.And what are those "get" and "set" calls?[code]......

I recently asked a question about translating a code sample I found on on the internet from C# into VB and I was given links to websites that automate code translation [URL].. I am very new to VB and unfortunately the VB that the translators returned doesn't compile in Visual Studio 2010. I am hoping someone can help me fix the non-working portion of VB code.

I am writing a program in visual studio to exchange data with a webservice. The webservice, Kareo.com, gives an example of a program but it is in C# - I am trying to replicate their program in visual basic, which is the language that I am more comfortable with. I got most of it to work but am running into problems with two lines "patientCase.Policies = new InsurancePolicyCreateReq[] { primaryPolicy, secondaryPolicy };" and "newPatient.Cases = new PatientCaseCreateReq[] { patientCase };"the C# version of the entire program is below.

I have this piece of VBNet code that i would like to translate into javascript:
Dim phone_check_pattern = "^(+?|((+?[0-9]{1,3}))|)([ 0-9.//-]|([ 0-9.//-]+))+((x|X|((e|E)(x|X)(t|T)))([ 0-9.//-]|([ 0-9.//-]+)))?$"
System.Diagnostics.Debug.WriteLine(System.Text.RegularExpressions.Regex.IsMatch("test input", phone_check_pattern))
my translated result:
var phone_check_pattern = "^(+?|((+?[0-9]{1,3}))|)([ 0-9.//-]|([ 0-9.//-]+))+((x|X|((e|E)(x|X)(t|T)))([ 0-9.//-]|([ 0-9.//-]+)))?$";
alert(new RegExp(phone_check_pattern).test("test input"))
However when i run it it has error Uncaught SyntaxError: Invalid regular expression:: Nothing to repeat
(my VbNet code doesn't have any error though)

I want my code to look at a textbox to determine which letter is in it, & assign a numerical value to a second textbox, based on what letter is in the first textbox.[code]The problem is that, when I step through the code, I can see that Form20.txtGrade1.text DOES EQUAL "C", but my code skips over the part that says Form20.txtGrade1a.text = "4". Instead, if I hover over that part, I can read Form20.txtGrade1a.text = " ".When I do not step through the code, and just run it, I see the two textboxes, with the first one containing the C, and the second one is just blank.

I was wondering if someone could translate this code into a more understandable code. It is suppose to be a function that accepts an item name its cost and its quantity. and adds one more array element to ."items" variable and assigns the given name and cost and quantity.
Public Sub AddItem(ByVal strName As String, ByVal dblCost As Double, ByVal intQuantity As Integer)
Me.items=DirectCast(Utils.CopyArray(DirectCast(Me.items,Array),New Purchase(me.itemsCount + 1)-1){}),Purchase())
End Sub
This is the translation i made but i don't think it is correct.
Public Sub AddItem(ByVal strName As String, ByVal dblPrice As Double, ByVal intQuan As Integer)
Dim items As Purchase() = Me.items
Dim itemCount As Integer = Me.itemsCount
For itemCount = 0 To items.Length - 1

While reading this threadthe code sample there came from MSDN, which was used to demonstrate the use of a delegate. I know what Delegates are. And I know how they work when it comes to things like crossing threads and even sinks.... how ever, the sample given is a simplecontrived example, and I'm wondering why/when would I use a delegate in this situation? Or in any situation? In my head, it seems it would have been easier/cleaner to call the function pointed to directly...
