• Windows Forms serialization of subclassed treenodes

  Hi, I am new to C# and .NET, but I have some programming experience in other languages/libraries. I am using C# and Visual Studio Express.

• .NET Development about *.ashx setup

  hi i don't know how to use *.ashx to take user request  about rar file. ( example: www.host.com/sample.rar  ) in asp.net 1.x , we can use a implement IHttpHandler dll with below setup to take it, but how should i do in asp.net 2.0 now thanks  <httpHandlers>   <add verb="*" path="*.rar" type="namespace.classname, assemblyname" />  <httpHandlers>     Hi ShengYan. You cannot use .ashx this way. If you want to handle .rar by using your own handler class, you should first tell IIS to delegate .rar request to ASP.NET engine, which would lead to modifying the IIS metabase.

• Visual C# Referenced DLLs - How to dynamically update the path of the reference dlls in another solution?

  Hello, I am working with 2 C# solutions right now, 1 is the main application we are creating (let's call it MainSolution.sln for now), the other is a unitTest solution (UnitTest.sln) created as a separate solution file, as the main solution consists of too many projects and compiling it takes a long time. It was created separately also because different groups of developers can work on the respective solutions they are tasked to do. In the UnitTest solution, we create unit tests for the main solution classes, hence, for each project in the unitTest solution, I've added references to the respective main solution dlls. A typical full path of the Main solution's DLL is C:\MainApp\<foldername>\bin\Debug\<filename>.dll I'm cur ...Show All

• SQL Server ASYNC_NETWORK_IO Qyery running slow

  I am running a Stored procedure which select from a table and returns approx 800000 records. When calling from any client machine it takes long time to return the result (90 sec). It waits for ASYNC_NETWORK_IO which is pushing the result to client. If select statement is used with TOP operator to return less number of records it executes faster. When calling from the server the stored proc returns data in 13 sec with all records. In another machine of identical HW and configuration this problem is not there. Can anyone help how to improve ASYNC_NETWORK_IO issue Environment SQL-2005 SP1 64 bit Standard on Active/Passive cluster Windows -2003 Ent.
