I'm helping my company upgrade from VS 2008 to VS 2010. Somewhere in the middle of all the testing, I'm getting a MissingMethodException saying "Method not found: '!!0 (namespace).(etc).(etc).(function(parameter))'."
Does the '!!0' provide any sort of clue that anyone knows of (Google doesn't recognize exclamation points in its searches)?

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?

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?
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.

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?

View 3 RepliesIs there a possible way to refer an object through it's name in Vb.Net?The case is, I have menu items created in my designer with names such as MenuA, MenuB and MenuC.On the database, I created a table consisting the list of all available menus in string format : MenuA, MenuB all the way to MenuZ.
Also I created a dynamic table consisting the user permission, what menu is accessible by a certain user.So when I started the app, it will get the name of menu assigned to the logged user, and start to turn the Visible property to TRUE.If it was a Control, I would just loop through it by Parent.Controls.Find(FoundMenu, True).My problem is most of it is not a control, it is an Item added to the Control, or even another SubItem added to the Item.So how can I found an object in my UI only by it's name?
SearchQuery = "SELECT menu_name FROM tbl_menulist menu, tbl_user user WHERE menu.id_menu = user.id_menu"
QueryReader = ExecuteQueryReader(SearchQuery)
QueryReader.Read()

View 11 RepliesI have a bunch of string variables, string1, string2, string3 etc.At the end of my program I want to write these strings to a file, but I don't want to have to laboriously type out string1, string2, string3 etc.
It would be much easier to use a loop to dynamically refer to (string & loopcounter), ie reference the variable by dynamically concatenating its name from a string and a number. Python can do this with eval(). How does VB do it? I can think of loads of examples where it'd be useful. Otherwise I have to type out all the different conditions and that's not efficient.
