VS 2010 Call A Shared Sub In A Different Class - Error "No Source Available"
Mar 30, 2011
I keep getting "No Source Available" when I try to step into some of my code. Example - KBRStandards.ApplyMultiLeaderStyle() I can not seem to understand what is happening here. I think I have changed a setting, but no idea what it is. I have tried "enable just my code" in the debug options.

I have a class like this:
[Code]...
It works, when I make getBar methods public, but I don't want to expose these unneccessarily. Why I can't call private shared methods from a public one in the same class is over my head. I'm using .net framework 4.0 in a web application.

I have just a form in my VB.Net project and even when I try debugging that - there is nothing going on besides the form being loaded - I get the error: No symbols are loaded for any call stack frame. The source code cannot be displayed.

I have a Windows form Application that I am creating, could also be a Windows Service that I need to run.There are basically 2 Classes that were converted from java to vb.net and 1 xml file to this. for testing purposes I would like to use the Button.click event to manually run the code.However i get an error when trying to call the sub/function the normal way.I even tried to put this classes information in the Public Class Form1 but it keeps on giving me errors.This is the Sub:
Shared Sub Main(ByVal args() As String)
so how do I call it from a Button.click event?
normally i would just do a "call main()" and it works however this time it is not because of the (byVal args() as string)

I've got an project that whenever an exception is throw will generate an error log. It was debugging fine so I decided to build a test version to let some co-workers try out. The build didn't work exactly right and I had to alter some reference properties to get it to build. Now I have the following error, "Reference to a non-shared member requires an object reference."The red highlighted text shows "reference to a non-shared member requires an object reference.

This might be a dumb question, but is it possible to call the beginning of a class from a different part of the same class?Here's the scenario... I have a class which has several subs in it. One of the last subs features a conditional statement. If that conditional statement is true, then I want the class code to be executed again, from the very beginning of that class.

just because you can do something, it doesn't mean it's good programming practice. To that end, I have a question about calling a public property from inside the class in which the said property resides. It seems that I can call it, similar to a sub, using me.property, but is this good programming practice?

I seem to be drawing a blank. I'd like to create a "shared" variable that is shared with all instances of a class but not classes that inherit from it. For example.Class A: Shared list As New List(Of String): list.Add("A")
Class B Inherits A: list.Add("B")Class C Inherits B: list.Add("C")The end result I'd like is that any instance of A has just A in the list. Any instance of B has A and B in the list. Any instance of C has A, B, and C in the list. I can accomplish it by creating Instance variables, but I have to construct the list for each instance of a class. I'd like to construct it once for a specific point in the Hierarchy and then share it accross other instances of that class.

This is another one of my "I think it's not possible but I need confirmation" questions.I have a base class for a bunch of child classes. Right now, this base class has a few common properties the children use, like Name. The base is an abstract class (MustInherit)Technically, this means that everytime a child class is instantiated, it lugs around, in memory, its own copy of Name. The thing is, Name is going to be a fixed value for all instances of a given child. I.e., Child1.Name will return "child_object1", and Child2.Name will return "child_object2".

I have extended an Entity Framework 4 entity class with a calculated property in a partial class. This member is not available on the client to which the entities are exposed via WCF RIA Services.when using C# appears to be changing the extension of the partial class file from .cs to .shared.cs. I tried this with my VB.Net solution (.vb to .shared.vb) and got a long list of errors. I believe what happened is that the partial class lost its association with the entity on the client - it inherited from object rather than EntityObject.
My best guess is that this is related to the way that VB.Net handles namespaces.Each project has a 'Root Namespace' which is prepended to anything that is defined within a code file. C# has a 'Default Namespace'which is the namespace into which new types are placed by default - via a namespace statement within the file.The partial class is probably having the client namespace prepended to it which puts it into a different namespace than the entity with which it is associated on the server.Is there any means of extending an entity in such a way that those extensions are available on the client via WCF RIA Services and VB.Net?

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

I've got a shared class (static in C#) which mostly carries some settings data that any class in the application can read and sometimes write. Also there are some static properties which holds some internal states.
Now I want to revert this class to initial stage of it. With all default variables etc. Assume that the user want to reset the current state and start over without restarting the application.
In a singleton model I'd simply renew it with something like this :
Public Sub Reset()
_Instance = New MyClass()
End Sub
However this is not possible in a Shared class. Or should I switch back to Singleton?

I have no idea what is going on here but it is strange to say the least.I created a new solution in VS2008Pro under windows 7 This solution has 2 projects one for the pc and one for a CE based device.There is one class module which is shared between the 2 projects.In VS2005 under xp this same basic project worked fine but here I am seeing error messages that appear out of no where.
Example the CE portion flags 3 lines initially 1 related to a file i.o function and 2 others related to socket methods. All three of these were supported in VS2005 using framework 2.0 which is the same framework I am using here. This is just the tip of the ice berg however.If I attempt to run the code it runs fine for the pc client and of course not for the CE device. If I make any kind of change, add a line, comment a line or just add a comment I get lots more errors with odd messages that are not even valid.
In one case after I saved it jumped from 3 errors to 30, in another case to 50 and yet another to 144 errors yet the only errors that were present were the original 3 that were flagged.The ide threw errors like Try Catch must end with matching End Try.Get no longer supported ' apparently referring to the binary file get but here it is used as the get portion of the property.Get must end with matching end get.It also started complaining about functions and data types.For example saying "an is not declared" pointing to the word Boolean Or telling me my functions are not declared point to only 1/2 of the function name.
I do not see any errors in the code and it reports no errors in VS2005 under XP.As a test I tryed adding a new property to the project after it was telling me there were 144 errors. I allowed the ide to do most of the work and when I hit enter the errors went back to 3. Then I saved the project and the errors went to 105 pointing first at the new property just created.

I have a function that 2 derived classes use, but the third doesn't, would it make sense to just leave it in the base class, even though one of the 3 derived classes doesn't use it?The only way I could think of disallowing the third class is to basically create an intermediate class that is derived of the base, then the 2 that use the common function are derived off the second class.
Is it possible to prevent the 3rd class from using the function, while letting the two that are supposed to use it, use it?Does that just seem to go overboard, I mean as long as I don't "try" to call the function from the 3rd class, it shouldn't be a problem, I just was interested if there was a way to prevent it all together without a lot of hassle.

I have large group of functions that I would like to store in basically a library and simply call the functions from the controls on my forms. Back in VB 6 I would have done this with a module, but now I have been told that a Public Class is the correct way in .NET. How should I go about doing this?

I have a class in a shared library, that I have added references to on both the webservice and the client project. One of the functions in the webservice returns a list of this class.
when I try to cast the return value into a List of the class on the client side, I keep getting an error telling me that a 1-dimensional array of type '<webservice.class>' cannot be converted to type '<sharedlib.clas>'.
The reason that I put the class into the shared library, was because I wanted the webservice to return strongly typed data, but I also have a couple of methods in the class. I dont care about them on the server side, but they are needed on the client side. I figured that this would be the "better" method, since in a shared library it is only declared once for both projects.

I have created a Interface and a couple classes that implement this Interface. I am in the process of developing a Shared Class that utilizes the functions that each of the individual classes have, due to the interface implementation.What i need to know is how do i develop this Shared Class so that way each of the methods within it are restricted to a single data type. This single data type needs to be restricted to any class that has implemented the Interface.
Some examples:
Public Interface IVector(Of T)
Sub Add(ByVal v2 as T)
[code]....
As you can see it would allow me to develop one form, since i have standardized the required Subs/Functions for any class the implements the IVector interface. As i am still in developement, i was wondering if my current understanding of the method generics is correct in its current form or what i would have to do to make the Generic Shared Class work in the fashion that i am looking for in the example implementation.
