With C# anonymous delegates, we can avoid declaration of extra method, I know in VB.NET they're not available, but is there a design pattern that I can use so that I can avoid writing an extra method each time? I need it for SPSecurity.RunWithElevatedPrivileges which will be used a lot of times in our code.

I am currently using the registry to get file descriptions for files. As an example, so that a DOCX file will return the description "Microsoft Word". I am doing this from the HKEY_CLASSES_ROOT registry key.However, registry access is extremely slow, and I need to do several thousands of these. Is there an alternative way to do this?

E.g. minimizing the actual application etc...I know how to handle those in code but that is painstaking as I have to think of every possible event which would result in a problem then manually code for the moustaches relative actions. So, I would like to know:

I've got an app which uses a background worker to copy files. It works fine but some files are quite large and it "appears" as though the app isn't doing anything. Is there an alternative to the File.Copy method of copying files so I can report on the progress of individual file copies, like the percentage complete?
View 19 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 am using a .Net JavaScript implementation called Jurassic to run user-controlled scripts within my .Net 4 WPF application coded in VB.Net - C# answers are fine. The script engine runs on its own thread and provides an API for the script to interact with my application. This all works really nicely until a user executes a script that causes an infinite loop and takes out a core of the processor.
[Code]...
The reason I care about keeping the thread alive is because the user who wrote the script and the user who is running it may not be the same, and I want to keep the experience as smooth as possible the the user running the thread. There also might be legitimate situations in which a single JavaScript function would run for a long time and I do not want to kill that, I just want to stop being allowed to hog the resources.
Solutions that involve stopping the thread from slowing down the system but that still show high CPU usage are not preferable because I do not want the user to wrongly feel that the application is resource intensive.

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.

Can I make an Extension method for all the subclasses of System.Object (everything)?
Example:
<Extension>
Public Function MyExtension(value As Object) As Object
Return value
End Function
The above functions won't work for object instance:UPDATE The problem seems to occur only in VB, where members of object are looked-up by reflection (late-bound).UPDATE AFTER ANSWERED.FYI, as vb has an advantage that C# lacks that is, members of imported Modules are imported to the global scope so you can still use this functions without their wrapper:Dim myObj2 = MyExtension(myObj1)
I had a code segment on an asp.net page in the code-behind file. I decided to move it into a public subroutine in a module (general_functions.vb). Once I did this, however, the code no longer works - it throws an error. On the original code-behind I replaced the original code with a call like so:

I have an interface ITest with a method GetResult(). I have a class Test which implements ITest and thereby defines private method GetResult().
Next I create an instance of Test in a different class. The code is as below:
Module NewClass
Public Sub New()
Dim i As ITest = New Test()
[Code]....
I am migrating existing code from VB 6 to VB.NET and hence I'm not supposed to change the access modifier of GetResult. Leaving it Private will throw InvalidCastException Unable to cast object of type 'System.Object' to type 'ITest'
Object type variable o is used in many places and hence I don't want to change that. And yes, Test implements ITest.GetMember with a different name.
I have tried several versions of this with no luck. The casting of the worksheet works as my data is entered in other parts, but I have a section where I need to add data 1 column right of the cell containing the 'str(0)' value.

Our company has an app that load their components by System.Reflection.Load (By the way, an awesome technique )But, we start to monitorate the application and detect a extrange grow up of memory (actually when our application still all day on air, their allocate memory on task manager is 200 MB plus memory) And all of our components (60 plus DLLs) is load by this technique.My doubt is how to deallocate this assemblies or how the best way to deallocate any assemblies loaded by the System.Reflection.Assemblie.Load method?
