Multithreading Overload Resoultion Error
Jan 23, 2012
I am attempting to use multithreading in one of my VB programs for the first time in attempt to make it more efficient.I have some code that starts the thread but I get an overload resolution error.When initialitzing the thread I am calling a boolean function and not a Sub, but I am not sure if that is the problem.I think the problem may be that the class in which I want the thread to start in has Option Strict Off while the class initalizing is set to Option Strict On.I will post my error and the code which is causing the error.

Can you tell me how to change screen resolution using directX and automatically passing UAC. It should also turn back to the original resolution when the user exits the program.

I have a little problem here. I am getting an error which they are jumping on this statement: a.Proxy = New WebProxy(Address.Text, Ports.Text). I have removed the equal to replace with the Address.Text and Ports.Text, I have tried to included And statement and the '&' in that statement, but I keep get the messagebox. The ip I am connecting are working well.
Here it is the
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Try
Dim a As HttpWebRequest = DirectCast(HttpWebRequest.Create("http://whatismyip.com/automation/n09230945.asp"), HttpWebRequest)
[code]....
Error: Overload resolution failed because no accessible 'New' can be called without a narrowing conversion: 'Public Sub New(Address As String, BypassOnLocal As Boolean)': Argument matching parameter 'BypassOnLocal' narrows from 'String' to 'Boolean'. 'Public Sub New(Host As String, Port As Integer)': Argument matching parameter 'Port' narrows from 'String' to 'Integer'.
I shouldn't have the messagebox displaying on my screen while I am connect to the ip. I have tried with the dim statement to included the textbox strings, but it doesn't help. how I could included the strings of the textbox in the a.Proxy = New WebProxy statement?

I have created a solution where no problems occur when debugging. After copying the complete solution to another folder i cannot debug this solution. I receive an error "Public Property DisplayName As String' and 'Public ReadOnly Property DisplayName As String' cannot overload each other because they differ only by 'ReadOnly' or 'WriteOnly'." in the web.g.vb file. I deleted the web.g.vb file and build the solution but this does not solve the problem. (The original solution debugs withoud any problem)

The error occurs at: For i As Integer = 0 To txt_load.Lines.Count - 1..The project exists of 2 rtb's. One with a list of lines. The other will be filled with the converted lines. The main reason that I use it is that I want to use the app during the conversion. The second is that I want to learn how this works.[code]

What I am doing is generic and has been done a thousand times, but I can't figure out how other programmers do this.
I am working with the Law of Sines to return an angle of A. There are two combinations, for instance:
Return Angle A given (side b, side a, angle B)
Return Angle A given (side c, side a, angle C)
----Note: All together there would be six, two for each angle)----
I can't overload the functions because the signatures are not unique. The parameters and return type are primitive type Double.
The use of Aliases works for reading the code but does nothing to resolve my issue.
One approach I thought of was to create a structure for each side and angle; however, I don't want to create any more complexity than needed.
Another solution could be using a strategy design pattern?

I've done plenty of Method Overloading, but now I have an instance where I would like to Overload a Property. The IDE in Visual Studio seems to allow it, since I can actually set up the two overloads, but I get an error saying it is not valid because they only differ in type. I think I'm missing something in my syntax?I want to be able to use two (or more) different custom classes as the Type for my property.
Public Overloads Property myFlexibleProperty() As myCustomClass1
Get
Return _myFlexibleProperty1

I'd like to do a kind of overload of the actions in the controller.
Is it possible? 'Cause I havn't found any info about it. And when I tryed, I got this error.
The current request for action 'Create' on controller type 'InterviewController' is >ambiguous between the following action methods:
System.Web.Mvc.ViewResult Create() on type

I've tryed few things to get what I wanted. The last one was to copy what was done in the "Edit" action, but for an empty rank. (so I created an empty rank in my DB). I don't think it was a good idea (imagine someone wants to update the DB where idOpportunite = 5...)

I want to catch the event of deletion, renaming or copying a file in Windows Explorer. For example, if a folder contains the files "test.a" and "test.b", and that I remove "test.a", then my program will remove the two (same for copy and rename).I know how to add an entry to the context menu of Windows. But the goal isn't to add functionality to Windows. The goal is to redefine an existing function.

Is there a way to use CodeDom to generate an overloaded operator in Vb.net? I want to generate this:
Public Shared Operator =(ByVal x As MyType, ByVal y As MyType) As Boolean
Return x Is y
End Operator
The closest hack I can think of to do this the following:
Dim eq As New CodeMemberMethod()
eq.Name = "Operator ="
eq.Parameters.Add(New CodeParameterDeclarationExpression(New CodeTypeReference("MyType"), "x"))[code]....
Which generates this, close but obviously wrong:
Public Shared Function Operator =(ByVal x As MyType, ByVal y As MyType) As Boolean
Return (x Is y)
End Function

I am working on this project and I am suppose to overload the method to allow strings instead of integer. Allow the user optionally add a thried string from a third text box. Okey I am trying to under stand this good. This is the code I have:
This is my overload class
Public Class OverloadEx
[CODE]........................
So with my overload class instead of integer I should put string there? If the user clicks the add button it will allow the user to add all 3 text boxes but when the user click the add string it will allow the user to add all three text boxes to string. So do I click the add string button to overload it to that one just like I did with the add?
