LINQ To SQL Classes Not CLS-Compliant?

Aug 5, 2009

I'm using LINQ to SQL as my data access layer for a new project.I have added my database tables to the designer and all is well.Whenever I use one of these classes in a function, Visual Studio warns me that 'Type xxxx is not CLS-compliant' or that 'Return type of function xxxx is not CLS-compliant' Is this a problem with the classes that LINQ to SQL generates? Does it matters? Can I disable these warnings anywhere? My VS error list is clogged up with these warnings making it hard to see anything else.

Return Type Of Parameter Is Not CLS-compliant

Jun 28, 2010

I have a base class with a static function that returns a typed dataset. I have several classes that inherit the base class with a non-static function that returns the same typed dataset. On these methods I get the 'Return type of parameter yadda
is not CLS-compliant' I don't understand where this is coming from. I have non unsigned integers/etc. in this dataset.

Practical Limitations With Assemblies Not Marked As CLS Compliant?

Mar 21, 2012

As an OSS library author, I've always tried to make my stuff CLS compliant. But MS doesn't make this easy. They often put you in catch-22 situations, such as the following:You cannot have a protected variable differing only in case from the public property.You cannot have protected or public variables starting in an underscore or 'm_'. If you want to make a class really extensible, you often need to have protected variables matching public properties. Your least ugly exit is to add a suffix to the variable, like "Var" or "Value". That's nasty and unacceptable to me. I like clean code.I know of no .NET languages that don't support variables starting in an underscore, and I've used them in many places where the variable needs to be visible to subclasses.

I'm tired of the warnings, and I'm planning on turning off CLS compliance at the assembly level on my 30+ C# libraries.Are there any actual problems with turning off CLS compliance on libraries? Any real problems with doing this? Microsoft has issued unheedable guidance on software for decades, with less that 5% of it being worth the bytes it was encoded in. I can't find any evidence that this best practice has any real effect on anything. But, to be careful, I'm checking. And no, this is not a duplicate of the inverse of this question: Any reason not to mark a DLL as CLSCompliant?I'm looking for actual results and effects here, not the advice of a MS intern. For example, if IronPython, IronRuby, or F# are unable to read or write a variable starting with an underscore, that's an effect, although it would only cause a problem for users subclassing certain objects. If a language or tool is completely unable to use an assembly unless it is marked CLS compliant, now that's a big deal.

C# :: Hide Non-CLS Compliant Code From Projects Using Other Languages?

Mar 12, 2011

This question is more out of curiosity than a project requirement or a problem.I have a Non-CLS compliant code in one language (say C#), and I need to use it like that only in my current language (across projects, so making internal is not a choice), and at the same time want to allow other languages (say VB) to be able to call the conflicting implementations without generating compile time error.

For instance,
//C#
public class SecurityService

How To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010

Oct 12, 2011

I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?

I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)

What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.

I have just started using VB, and from what I have found so far it seems like the tools you have is

- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function

As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.

Function Syntax - Call A Function With 2 Arguments When The Function Is Only Defined For One

Apr 1, 2010

I'm trying to undersatnd the syntax of calling a funciton and it seem confusing when I'm using a web service in ASP.net. Maybe this question should be in an ASP forum, but it is a VB question. This simple web service allows you to type in your name and it response with an alert box with you name.

My question is, How can you call a function with 2 arguments when the function is only defined for one. I understand that the second argument is actually a method that handling the respons, but how can you interchange function arguments for methods and how do you know that there are methods for

Setting A Variable To Accept The Result Of A Function By Calling The Function With Many Parameters

Feb 17, 2011

I'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.

For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.

Call A Function From Inside Another And Suspend It Until The Called Function Is Finished

Jan 25, 2010

How can I call a function from inside another function and suspend the calling function until the called function is finished? I hope I can get some replies because I don't know how to ask the question and make sense:).

Anyway what I am trying to do in steps:

1. The user clicks button1 which triggers the click event.
2. From the click event I call a function
3. I then pop-up a form, that has instructions for the user to read.
4. After the user has read the form he will click the "Done" button and return to the calling function.

The problem is the the calling function continues to execute. I want to stop execution of the calling function until the users clicks the "Done" button on the instruction pop=up. I know I can use a msgbox but the instructions can be lengthly and does not look good in a msgbox.

I have tried the Call method with return in the "Done" button click but I can make that work. I also tried a goto statement but I can get that to work either. In the call statement I said call frmInstruction.show() and it got there but as I said the calling function continued to execute.

Threaded Function Call Slower Than Calling Function Directly?

Sep 14, 2010

I have a function where I am performing a lot number of database operations inside a Sub. The operation when called directly like:ExecProcess()

takes about 11 seconds to run.However, if I create a Delegate, and call the sub using BeginInvoke(), the very same process takes over 40 seconds to execute.Here's the threaded code:

Protected del As ProcessDelegate
Protected Delegate Sub ProcessDelegate()
del = New ProcessDelegate(AddressOf SELocal.ExecJob)
Dim cb As New AsyncCallback(AddressOf Me.ExecJobComplete)
del.BeginInvoke(cb, del)

Anyone know what may cause a function to take longer inside a new thread, rather than calling directly?

To have a function that takes the average (which is calculated by a different function) say for example the average is 6, now the function is to take the number 6 and get the variance from six to another number lets say its 12 so this will return a calculation of 50% variance. now here comes the issue, i have it calculating the variance how ever lets say that there is a score that is 0, how can i make it calculate the variance without taking count for that 0? i guess you can say i need it to "skip" if its a 0.

Override A Function And Call A Function With The Same Name From The Grandparent Superclass?

I am attempting to inherit an ASP.NET RegularExpressionValidator and add some functionality to it. I inherited the control and added my custom properties. However, I would also like the client-side functionality to call a different JavaScript function.

In order to do that, I will need to supress what is happening in the AddAttributesToRender method because the name of the function is hard-coded there. Here is what comes up in Reflector for the AddAttributesToRender function in RegularExpressionValidator:

Note: I tried to add the expando property before the parent class does to see if the code would check for its existence and skip it, but that just causes an exception.
