Client IP Address In C# (.asmx) Webservices?

Mar 28, 2010

I am using ASP.NET (.asmx) web services with Silverlight. Since there is no way to find the client IP address in Silverlight, I had to log this on the service end.

These are some methods I have tried:

string strHostName = Dns.GetHostName();
string clientIPAddress = Dns.GetHostAddresses(strHostName).GetValue(0).ToString();

All the above methods work fine on my local system, but when I publish my service on a production server, it starts giving errors, Error: Object reference not set to an instance of an object. StackTrace:

at System.Web.Hosting.ISAPIWorkerRequestInProc.GetAdditionalServerVar(Int32 index)
at System.Web.Hosting.ISAPIWorkerRequestInProc.GetServerVariable(String name)
at System.Web.Hosting.ISAPIWorkerRequest.GetRemoteAddress()
at System.Web.HttpRequest.get_UserHostAddress()

Start Batch Job From IIS / Start Exe File With System.Diagnostics.Process.Start With Another Account Is Disabled?

Oct 28, 2010

What is the right approach when users (authenticated domain admins) should be able to start batch jobs (usually exe files) from an IIS (7.x) aspx (c#) page? This is an intranet site. The batch jobs have to run on the web server as Domain Admins. The website pool is executed by network service or some similar restricted account in AD.

Approaches I can think of (and their disadvantages):
1. Start exe file with System.Diagnostics.Process.Start with another account. This feature is disabled in IIS 7.x, how do I allow it?

2. Create a sheduled task and call scheduled task-api. This unmanaged dll is giving VS compiler warnings because it's unsafe to call from managed code.

3. I suppose there's a better approach, because the previous suggestions doesn't appear safe or robust.

C# - Registering Routes On Session Start Not Application Start?

Jan 26, 2011

I am trying to register the route collection in .net based on each session. The code I have works fine, you goto website/username and it loads the correct sub pages, but you have to restart the application to goto website/username2 to load those sub pages. But when the application is restarted the second one works, but then not the first one. Is there some way to create a different route collection per session not per application using system.web.routing.

C# - Start Timer On Web Application Start

Jun 8, 2010

I would like to start a System.Threading.Timer in my application when it launches (maybe deploy is the correct word). I have seen that you can use Application_Start() but this is only fired once the first request comes to the application. I need the timer to start as soon as the application is running so that it can check for work to process even if a user is not interacting with the site. How can I get the application to start the timer once it is up and running?

Iis7 - Unable To Start Debugging On The Web Server - Couldn't Start Debugging VS 2010 - II7 - Win 7 X64

Jan 11, 2011

I am running Visual Studio 2010 (as Admin), IIS 7 on Windows 7 x64. I am able to run the ASP.NET web site in IIS 7 without debugging just fine, but when I press F5 to debug it, I get: Unable to start debugging on the web server. Could not start ASP.NET debugging. More information may be available by starting the project without debugging. Unfortunately the help link is not helping me much and leads down a heck of a large tree of things. I checked the following:

Security requirements — I don't recall having to do anything special before. The worker process in IIS7 is w3wp.exe. It says that if it's running as ASPNET or NETWORK SERVICE I must have Administrator privileges to debug it. How do I find out if I need to change something here? Web site Property Pages > Start Options > Debuggers > ASP.NET is checked. Use custom server is set to the URL of the site (which works fine without debugging). Debugging is enabled in web.config. Application is using ASP.NET 3.5 (I want to move to 4.0 eventually but I have some migration to deal with). Application pool: Classing .NET AppPool (also tried DefaultAppPool). Surely it shouldn't be that hard to install IIS, VS, create a web site, and start testing it?

This application will eventually be used by outside clients to consume data. When would you use WebServices and when would you use WCF? Is one more scalable than the other?
