Is it possible to prevent compiler warning caused by a static factory method returning an instance of an obsolete class? For example if an instance of an obsolete class (Foo) is created through a static method (Create) a compiler warning is caused by the factory method.
<Obsolete()> _
Public Class Foo
Public Shared Function Create() As Foo
[code]....
In C# the warning could be suppressed using "#pragma warning..." but I don't think that this exists within VB.Net. Migrating to C# is not an option due to business requirements.

I have set up a method in vb.net and in xcode for encrypting a string using as far as i can tell the same parameters for an AES encryption.I've looked all over the place but cannot find information on whether they use the same encryption algorithm and settings.
this is the vb.net code:
Dim encryptAES As New AesCryptoServiceProvider()
Dim encoding As New UTF8Encoding()
Dim encryptor As ICryptoTransform
encryptAES.Key = encoding.GetBytes("12345678901234567890123456789032")
encryptAES.IV = encoding.GetBytes("1234567890123416")
encryptAES.Mode = CipherMode.CBC

I have VB.Net code in VS 2008 using an obsolete method, and would like to suppress the warning.Unfortunately, following the recommendation is not a good solution, because it requires using a different class, which works differently, in important ways.I'm trying to suppress the warning using System.Diagnostics.CodeAnalysis.SuppressMessage, but I don't know what to write as the parameters for the attribute, and can't find any relevant reference.
I should also say that, right-clicking on the error in the error list I don't have any 'Suppress Message' option.

I have upgraded a visual basic 2005 project to visual basic 2010 (.net framework 4.0). I want to list all obsolete functions used in this project in order to change it with newer ones. How can I treat obsolete functions warnings as errors in visual basic 2010 ms-build?
View 1 RepliesIn .NET you can mark certain methods as obsolete so that developers are alerted when they attempt to use the deprecated method.
<Obsolete("Do not call this method.")> Private Sub FormerMethod()
The thing is you can only do this within classes you control. What do you do when you want your developers to avoid using certain methods on classes provided natively in .NET or by a vendor?
For example, what if you want your developer to prefer some custom extension method on DataTable rather than Select. I'd hate to have to define a custom version of the DataTable class if only to deprecate Select. That would leave us having to police whether or not the custom table was being used.

If I follow the instructions, and use "AddWithValue" instead, the warnings go. But I can't figure out why I don't get these messages in the first project. It seems there is something different in their configuration, but I can't figure out what. Both use the same version of mysql.data.dll. And both are configured to show warnings in the same circumstances via the project>properties>compile menu. Can anyone suggest where else to check?

Is there any way to disable a specific warning. For example, in one of my classes are re-implement System.ICloneable.Clone. After doing so I now get a warning that states, "'System.ICloneable.Clone' from 'implements System.ICloneable' is already implemented by the base class 'XXX'. Re-implementation of function assumed."

View 6 RepliesI'm compiling a VB.Net 2.0 app (created in VS2008) using msbuild, and now I've added a generic return type, it's giving me the following:
Warning: Type library exporter
encountered a generic type instance in
a signature. Generic code may not be
exported to COM.
Having just spent ages removing all of the previous warnings, I don't really want to add a new one. Any idea how to get rid of it (aside from not using generics)?I don't know what details I'd put in the attribute, or what number to put in the project-level ignore list.
I have an app with a timer control, and the interval is set to 60000ms (1 min). so every min i have some event happen. thats pretty simple. however, i want to have a 15 second warning that the event is going to happen. so basically 45 seconds after my timer starts, i want a message such as "15 seconds left until event x happens".
would i have to use 2 timers? i guess im lost on the logic. i know how to use the timer control, but i have been googling all night trying to figure this one out. i have tried using 1 timer set to 45 seconds (for the warning) and another timer at 60 seconds(for the event) but they go out of synch after 1 iteration and will not consistently stay 15 seconds ahead of the other. i dont want to post any code i have, because it is all trash and i want to start over from scratch.

View 6 Replieswarnings got me thinking about old issues that always goofed me up when I was writing more VB.NET code.One of them was the fact that the compiler didn't warn if you declared a Function but never did an explicit Return statement or assign to the Function name. Running Visual Studio 2008, I just made a small experimental project, and it seems as though the behavior has never been fixed.I created a Visual Basic Console application, with the following code:
Module MainModule
Sub Main()
Dim test As Boolean = TestWarning()[code].....
I also went into the Project Settings and turned On Option Strict and Option Explicit.I also set the Warning Configurations so that "Function/Operator with no return value" was set to Error.I compiled the project and got no warning, and no error on the TestWarning() Function. This seems like a great place to put a warning, because it will default to False, and you may have simply forgotten to do a return. C# will error without a return statement. I thought that VB.NET did the same thing with the "Function/Operator with no return value" configuration. Is this a bug, or is there something I'm missing?
Edit: Further Experimentation
Function TestWarning() As Boolean
If DateTime.Now.DayOfWeek = DayOfWeek.Monday Then
Return False[code].....
If, and nothing in the Else, there is also no Warning/Error. It will simply take the default, even though you likely intended (via programming style) to have an explicit return. In this case, I explicitly returned False (which is the default for Boolean), so it's likely a hidden bug that I should have returned True in the Else.

I wrote a small VB6 program to monitor the status of a Shared Network Drive. In this case it's an external hard drive. The drive is used for backup. The program is invoked automatically when the computer is booted and runs minimized.
If the backup drive is not turned on or otherwise not functional then the program changes from minimized to a normal window and displays various statistics and a warning that the backup drive isn't working.
I want to make the warning much more prominent, like minimizing the program that happens to be running or displaying the warning window in front of the progrmam that happens to be running. I want something really noticaeble. The computers don't have speakers so I can't play an warning.wav .
This program is for advertising ads and prices are determined by which radiobutton is selected.This program uses objects created from a class .
