C# - Switch .NET Assembly For Execution Of One Method?

Jan 20, 2010

I have different versions of dlls for my .NET application and most of the time I want to use the latest one. However, there is one method which I run on a separate thread where I need to be able to select an older version of the dll based on some criteria.

I have learned that it is not possible to just load an assembly and then unload it within the default application domain (I can't just keep both versions loaded because then I'm running into duplicate definitions of types problem)

Probably I have to create a separate AppDomain, load the assembly there and then unload it. This application domain would execute just one method on a separate thread and would work with a different version of the library.

Security :: Control Method Execution With Attributes?

Mar 18, 2010

I'm working on an application that has moderately complex security requirements. Each user can have several permissions like "Load," "Save," etc. Is there a way I can use custom attributes (or perhaps even an ASP.NET built-in security protocol) that will let me hard code a permission requirement above the corresponding method? Then ASP would have to make a call to a security method which I made which can see if the user has that permission in their permission set. For example:

[Code]....

And if the user logged in does not have the permission, fire off some other method that can display an error. I've looked at the role based security that asp.net offers and it doesn't suit our needs because we have many roles and they differ by organization.

Recompile The Assembly To Use The New Mono Assembly Versions The Assembly Is Closed Source?

Feb 18, 2010

I have recently discovered that I am affected by this bug http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71515.html

Well,at http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71529.html they say the work around is to create a global policy assembly and redirect the assemblies that way since it is not read from the web.config.

How do you actually do what they describe there? There is a huge documentation gap in that area with Mono.Also,I can't just recompile the assembly to use the new Mono assembly versions because the assembly is closed source.(but it does work with Mono.)

Web Forms :: Referring An Assembly In Project / Without Adding Assembly Reference, It Still Accepting And Running Code?

Jul 5, 2010

Before using any class in your website project/page we have to add it's assembly reference to our project. Right?

Now, when I am using SmtpClient class from System.Net assembly after adding the System.Net.Mail namespace in namespace node of application's web.config file but without adding assembly reference to the project, it still accepting and running the code. Why?

I enquired the machine's web.config file located at C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIG but didnt find assembly reference for System.Net there also.

So bit confused how it is working and where the assembly reference has been added and how?

Create Shared Assembly And Use That Assembly In Web Application?

Jun 3, 2010

I just want to create Shared Assembly and use that assembly in our application.I am using VS 2005.

Step 1

I am trying to build a dll.

Create class library project <TestDllHell>.

Under that project add CalculationArea.cs file.

[Code]....

Then TestDllHell.dll add into GAC successfully.

Now I want to use it in my Website project so did the following steps but unable to view that dll in .Net Reference List Box.

•I go for Run regedit to edit the Windows Registry.

•Navigate to the HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkAssemblyFolders key.

•Right click on the AssemblyFolders key, then select New > Key. Enter the name of your assembly (without the .dll extension).

•Double click on the key's (Default) value. The Edit String dialog will appear. Enter the full path of the folder where your assembly resides. Note that all assemblies in that folder will appear in the Visual Studio list.

•IMPORTANT! You must exit and restart Visual Studio to see your assembly in the Add Reference dialog.

My question is that

How can I get that dll in my add reference assembly List .Net section?

And if I modify that dll(TestDllHell.dll) then again register in GAC then version will be different,So how can I told my client application that which dll you choose?

C# Want To Switch On Enums?

Jul 2, 2010

I have an enum:

public enum Status
{
Incomplete = 1, Complete = 2, Cancelled = 3, Deleted = 4
}

Now on a certain page I wish to list this enum in a checkboxlist. This would be fine except that I want the text of each checkbox to display different text than the enum.

i.e the check boxes should say:"Not Processed" instead of "Incomplete"

"Processed" instead of "Complete"

"Void" instead of "Cancelled"

Is it possible to put this enum in a foreach and then switch on the status and update the text. Like so:var statuses = Enum.GetNames(typeof(Status));
foreach (var status in statuses)))
{
switch (status) [code]....

Should Switch To IIS7 URL Rewriting

Mar 5, 2010

I'm using Intelligencia url rewriting currently but have just leased an IIS 7.5 server to put my asp.net 3.5 site on. I installed the IIS URL rewriting module and was amazed at how easy it was to create rules. Creating rules with the Intelligencia url rewriter is complicated (at least for me). Are there any downsides to switching? Is there a reason for me not to move on to the Microsoft solution? This site isn't live yet, so I have time to switch

Site Uses Cookies - Need To Switch To Sessions

My site uses cookies. I need to have it use sessions instead. The reason for this is because there is a third party that needs to connect to it, and it's always requiring 3rd party cookies to be enable in the browser and that is annoying my customers. Is there any other way around this other than switching to sessions?

SQL Server :: Switch Two Field Data?

I pulled a fast one today. I imported thousands of records and accidentally put the FName in the LName and the LName in the FName. I don't have a clue how to write a SQL or TSQL that will switch them. I do have a parameter for the SQL though. WHERE User - System Import.on ASP.NET because this is my place for help instead of going elsewhere to a more specific type of forum just for SQL. I do only ASP.NET VB/CS development so this is my home to find all my answers. (99% of the time).
