I need to do a response.redirect to the same page. How can I do this without the page "refreshing" or "flashing"? I can't use updatepanels because, this is a search website and I want the user to be able to use the browser's back button. I have some search filters on the page, and each time a filter is clicked, I do a resposne.redirec...

The problem is, I will need to validate this cookie from an ASP classic application. From what I know, there are no built in cryptographic providers in ASP classic, thus I may need to copy/wri...
Struggling here, many documents I find are CF 1.0 centric and talk of the 2.0 changes to allow generics and typed DS'es on CF 2.0. Well, CF 2.0 has come and gone, and MS still shows these without update. I am not ready to jump into WCF, and my clients have a lot of older compact framework 2.0 machines. I am fortunate in that these We...
Good news! Since version 4.8 BerkeleyDB has c# interface. BerkeleyDB is a quite interesting thing for me due to it's non-SQL nature. I know it's an excellent tool if someone wants to store a lot of key/value pairs. And I know about 'attachable' tables. What i don't know is how to store hierarchical data with BerkeleyDB. Is it suitable f...
This seems like it should be something very easy to do, but every time I approach this issue, I end up w/ solutions that feel "less than elegant" Here is my basic question: If I am looping through a dictionary that I have ordered in a particular way, within any given point in the loop how can I "peek" or get reference to a dictionary ...
A C# client application we developed calls an external SOAP web service of a third party company. Now I want to trace the exact SOAP request envelopes that are being generated by the VS.NET-generated SOAP proxy in our application and transfered to the external SOAP web service. The method of using a network monitor like Wireshark (as d...
I have an application where my domain model just works. It's all very clear, clean and maps to objects very well. My problem is that it does not map to a relational database very well. With that in mind, I'm looking for object databases that play with .Net/C# reasonably well. Is there a defacto best in class object database for the...

But I want at the same query to use a Batch of SQL statements having the same result as this HQL Query (Want to make some record Counts) : IList results = s.CreateMultiQuery() .Add("from Item i where i.Id > :id")...
Is there a class or set of functions built into the .NET Framework (3.5+) to parse raw emails (MIME documents)? I am not looking for anything fancy or a separate library, it needs to be built-in. I'm going to be using this in some unit tests and need only grab the main headers of interest (To, From, Subject) along with the body (which ...

After years of ASP.NET development I'm actually quite surprised that I can't seem to find a satisfying solution for this. Why does an IIS ASP.NET site always seem to fall asleep (for 2-6 seconds) after a certain time of inactivity (after several hours), during which no HTTP response is sent from server to client. This happens on any typ...
Given this Itemgroup: <ItemGroup> <Foo Include="First"> <Value>1</Value> </Foo> <Foo Include="Second"> <Value>2</Value> </Foo> </ItemGroup> How can I get the Value metadata for the second item (2)? I'm thinking along the lines of: <Message Text="%(Foo.Value)" Condition="'' == 'Second'" /> But I don't know how to wri...

I'm looking at creating a tabbed interface which has user controls (possibly written by plug-in developers) within a tabbed or MDI interface. These plug-in controls could unintentionally freeze their GUI thread, and I'd prefer that they not influence user controls in other tabs. Much like Google Chrome creates a process for each tab; b...

I'm building a new web app that has a requirement to generate an internal short URL to be used in the future for users to easily get back to a specific page which has a very long URL. My initial thoughts are to store a number in a database and output it in a HEXADECIMAL value to keep it shorter than an integer. TinyURL.com seems to use s...
