I am getting an error when I try and run my service. I made sure everything in the project is VB .NET 2.0.This service used to work, but we have been making code updates... I did some research but I do not see anything relevant. Does this error mean that my function cause the issue? Or is it the List that is the issue?

I am loading an assembly dynamically and invoking a static method from it. The problem arises when the method uses a reference which is not trivial (e.g. mscorlib or System.Core) - I get System.MissingMethodException. I have tried going through the references assemblies of the loaded assembly and manually loading them all, thus forcing them to be loaded onto the AppDomain. I have checked CurrentDomain.GetAssemblies, the assemblies are loaded.

It also works on one other machine. However, three other machines are throwing exceptions.The situation throwing the exception is that I have a serial port I am accessing, which is open, and which has been successfully opened.

We are getting intermittent problems on a production server that we cannot recreate.There are two very strange things about the issue. Firstly it's a method not found error on the constructor (ctor) for an exception handling helper class and secondly we have custom errors switched on for remote users and this property is being ignored.
[Code]...
It has proven difficult to get information out of the team responsible for the production servers but I have managed to find out that as far as load balancing is concerned, this site is currently only running on one server (this can be made to switch over onto another if necessary). Given that this is an intermittent problem and there is only one server involved, then I find it difficult to believe that this could be an assembly issue. Surely if it was then the problem would occur every time?
following error message:

(using vb.net) On our intranet site we have an app that loads customer or vendor information and then allows the users to edit info and add/update/delete contacts. I'm not sure what really changed to this program lately, but I keep getting this error:
Method not found: 'Int16 DBLayer.DBTools.ExecuteNonQuery(System.String, DB)'.
This occurs when i try editing any customer info and the vendor contacts, but the program works when I try editing the vendor info/addy. Here's the program code. There's a seperate program on our webserver that contains the classes used. Here's the main code that calls the classes:
TO ADD CONTACT
M2MInterface.M2M.Customers.AddContact(Session("CustVendID"), txtFName.Text.ToUpper.Trim, txtLName.Text.ToUpper.Trim, Tools.RemovePhoneNumberFormat(Phone), Tools.RemovePhoneNumberFormat(Fax), txtEMail.Text, txtNotes.Text, False)

I am getting a
"Method not found: 'Boolean MyCompany.LibraryAssembly.SomeFunction (System.String)'"
Exception/error when running a VB.NET console application. The method is part of an external assembly and it is definitely in the assembly. The error only occurs at runtime when I go to enter the function that calls the method. I have the assembly referenced by my project and I am not copying it locally. Intellisense shows no errors, and neither does the compiler. I am loading the assembly statically not dynamically. I reference the from a local folder (not the GAC) although the same version is also available from the GAC.
I have:

Note: This error only occurs on one machine. On every other machine it works fine which makes me think something with the .NET assemblies was corrupted. It was working fine on the broken machine a few days ago.

I know there is a function Contains that returns true if string has a certain substing in it. But is there a function that returns the count of instances of that substring inside another string.
View 6 RepliesI found a custom ListBox that, strangely doesn't have an InsertAt method and I would like to add one. The custom ListBox uses an object instead of just a list of strings like a normal ListBox. I was curious what the logic behind inserting a new item at a particular index would be.The only thing I could come up with was add the new ListBoxItem at the end, then using the specified index, I could either keep moving ListBoxItem objects to the bottom, with the Add() method, from that index till the ListBoxItem at that index equals the one added, or I could use that index number in a "calculation" till I know I've moved the correct number of objects.
View 14 RepliesI have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.

I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.
I'm having an issue that, frankly, I don't understand. I've been developping a VB.NET application for months and today, when I open the solution file, and tried rebuilding it, I am getting several errors, all various permutations of "The referenced component 'SOMETHING' could not be found." There are 5 COM objects that it cannot seem to load (Excel, Office.Core, VBIDE, Word, and OISSERVERLib).
When I go into the References section, I see next to those COM objects, the path is now shown as "<The system cannot find the reference specified>". I've followed the steps outlined here, including updating the reference paths to directly point to the files, but nothing seems to be fixing the issue.
Does anyone know what could be causing this, or (even better) how to fix it? This is the first time in 4 years that I've encountered an issue like this.
I've attached a zip file containing a screen print of Visual Studio showing the errors.

When my application loads in Visual Studio 2010 I see this warning. Everything runs ok in it as far as I'm aware but I'm completely ignorant in this area. Could that cause me a problem and is there a way to replace that component? There is also the other warning you see in the screenshot.
Quote:Warning1Namespace or type specified in the project-level Imports 'System.Linq' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.
I did a search for the entire solution and it didn't turn up any Sysem.Linq anywhere. I looked at every Imports statement in my project and I don't have any Imports System.Linq anywhere unless it's somewhere where Visual Studio's quick find search doesn't see it.
In my ASP.NET app, I'm using classic ADO 2.8 to save some data into an Access database. (Or a Jet database, for those who insist that Access is just the front-end.) So I have a RecordSet containing some data, and I want to set the value for some fields, but first I need to know the field type. So I use the Recordset.Type property:
Dim fieldType = rs("MyField").Type
And that unexpectedly results in an error: MissingMethodException was unhandled by user code -- Error: Missing method 'instance valuetype ADODB.DataTypeEnum [MyProjectName] ADODB.Field::get_Type()' from class 'ADODB.InternalField'.
Considering that it is .NET itself that has created the .NET/COM interop assembly, any idea why?And here's the strangest thing: When the debugger stops and reports the error and takes me to the spot in my code where it happened, and it has that great feature by which you can hover the mouse over any variable etc. and it will show its value -- so I hover over the rs("MyField").Type part, and, lo and behold, it shows the correct value!So if it could evaluate it at debug-time, why did it throw an error at run-time?
