I am getting an exception when trying to servialize the .NET ServiceController class. It serializes fine when it's null but once I populate it I get a stackoverflow exception.So this works:

The following code is throwing Exception. I don't get what mistake I am making in the code. i think it is of some security rights issue. If so, how can I give the security rights to any user or application to access this windows service programmatically?

I've just started developing with .net CF 3.5 for windows mobile 6.5. I'm using VB 2008 as my IDE and I am having trouble with ServiceController.
Here is what I have so far:
Private Sub Stop_Service_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Stop_Service.Click
' Toggle the Messaging service -
' If it is started (running, paused, etc), stop the service.
Dim sc As New ServiceController("MessagingService")

The problem is with the bit in bold. The debugger says the following:
Error 1 Reference required to assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' containing the base class 'System.ComponentModel.Component'. Add one to your project.
I've checked and the system object exists but it is marked in the object browser with brackets as "Compact Framework". I have tried to remove this and replace it with one not labeled with "compact framework" and the error does go away but then the application doesn't run in the WM 6.5 classic emulator Producing a "failed to load all components. Please make sure you have enough space in storage memory or try reinstalling .Net CF error".
I am also having a problem with the ServiceController trying to stop a windows service could someone take a look at teh below and check I am doing it right please.[code]Got this code from a Google Search.

I already read a lot about exception handling and saw many different threads on the subject but still confused when creating class libraries like the following scenario.

i've done research and it's because it's using a GET method instead of a POST method... how the heck do you fix this if your using a FtpWebRequest class!?

We have a VB .Net windows application developed with VS 2005, framework 2.0.
The executable when run on a different machine throws the above error. It cannot be caught with the IDE due none of the developers experiencing it.
I am getting this warning after I have changed the computer. I just installed framework and visual basic 2010, trying to edit the application that I been working on and one of the main forms is giving me this error.

It is possible to catch an exception and throw a new exception which wraps the first exception as an inner exception: [URL] Also, if I call a function and it throws a certain error, but I catch it, will the calling code's catch handler execute? If so, and it is of a higher exception type, is this not wrapping the exception? eg I can throw exception ex of type IndexOutOfRange, log it but rethrow, catch a higher up exception and do something, or I can throw a new exception and wrap an inner exception like:

View 3 RepliesI'm relatively new to VB.NET and am having a problem when Databinding a Class to a Forms Controls. Basically within the Class, when Setting certain String Properties I heck that they are not Null/Empty and if they are Throw an Exception. The problem occurs when I bind the properties to textboxes - when the textbox is empty I expect an error to occur (which I will handle). So does anyone have any insight or solutions into why the exceptions are not being thrown when a textbox changed to an empty string?
A condensed example follows:
Dim a As New SomeClass("Random", "Text")
Dim f As New SomeForm(a)

I have project which is implemented in VB.Net using VS 2008. I install build on Win 7 64 bit machine an see a splash screen after which it thorws exception saying "The type initializer '<class name>'for threw an exception". The class is NotInheritable and the method which I'm trying to access is shared. The same project works fine on win 7 32 bit machine. The build is also compiled using x86.

I agree that for domain model code that using the "traditional" unit testing approach makes the most sense as this would lead to a design that is easiest to maintain. However, for code that deals with the .net implementation of Windows API related stuff (file system, services, etc), is there really an advantage to going thru the extra work to get "traditionally" testable code?
It's hard for me to see the disadvantages of using Microsoft Moles for things such as ServiceController (or the File object). I really don't see any advantage of doing the traditional approach in this case.
i just got my vista 64 bit and i was trying to use XPButtons.ocx

I have 2 classess. Role and User like this
Role
Public Class Role
Public Property RoleID As Integer
Public Property CreatedBy As User
[code]....
The situation is like when we create roles, we will save who created this role. So i have a CreatedBy Property of type User. Similarly when we create a User, we will mention what role the new user belongs to .So i have a property called "Role" of type "Role". This circular reference giving me StackOverflow exception as its recursive when i create an object of User class.How do i handle this ? should i restucture my entties ? how ?
I have created a class for Socket reads so I can create sockets on command. Due to performing a socket read, the program will freeze waiting for incoming data due to being on a single thread. So I created a separate thread for the reading of the sock and attempt to invoke an event to prevent multi-threading errors.
But I am getting an error when trying to Invoke: "Invoke or BeginInvoke cannot be called on a control until the window handle has been created."
How can I fix this or is there a better way to read a sock without freezing the thread?
Class for Sockets:
Option Explicit On
Option Strict On
Imports System.Text

Calling form code example:
Private WithEvents Socks As clsSock
Private Sub Sock_Connected(ByVal state As String) Handles Socks.Connected
MsgBox("Connected - " & state)

i have added a winsock control to my program. I know that vb 2008 dosent really support winsock no more but its needed for my project.Anyways i have form1 with a button that does "form2.show"This works as it should and opens form2 but when i add a winsock control to form2 then i get this error when i click the button to show form2
"An error occurred creating the form. See Exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"
I dont get it, there are no classes apart from the form class.
I created a class library containing some properties and methods, when I call a specific method that runs a sequence of tests, it reports "out of memory exception". When I take the same code and build a form.exe, I do not get the "out of memory exception".
