help needed on using SimpleWorkerRequest | Tech Off

Hi I am trying to use SimpleWorkerRequest, but I keep getting errors.

I currently have the following code:

StringWriter sw = new StringWriter();
SimpleWorkerRequest swr = new SimpleWorkerRequest("/test", @"c:\test\", "/test/Test.aspx", string.Empty, sw);
HttpRuntime.ProcessRequest(swr);
Console.Write(sw.GetStringBuilder().ToString());
Console.Read();

But for some reason I keep getting the following error:

[HttpException (0x80070057): Invalid file name for file monitoring: ''. Common reasons for failure include:

- The filename is not a valid Win32 file name.
- The filename is not an absolute path.
- The filename contains wildcard characters.
- The file specified is a directory.
- Access denied.

at System.Web.FileChangesMonitor.StartMonitoringFile(String alias, FileChangeEventHandler callback)
   System.Web.HttpApplicationFactory.SetupChangesMonitor()
   System.Web.HttpApplicationFactory.Init()
   System.Web.HttpApplicationFactory.EnsureInited()
   System.Web.HttpApplicationFactory.GetApplicationInstance(HttpContext context)
   System.Web.HttpRuntime.ProcessRequestInternal (HttpWorkerRequest wr)

I gave both the ASP.NET Machine account and the everyone group full rights to the directory. I can play arround with the paths, but that did nothing more than giving an "Bad request" error. I found a lot of samples on google, but they all don't seem to work (they are the same as my code).

Anyone got a working sample of SimpleWorkerRequest or can point me in the correct direction to solve this issue?

Thanks.

I think your 'page' parameter needs no 'test' portion.

The page parameter gives the same error with "Test.aspx" "/Test.aspx" @"\Test.aspx", that's the weird thing.

I just tryed to create the virtualdir in iis, to see if it needs to be set there first, but no good luck.

Edit: I just found a entry in google groups about it, more people seem to have the same sort of problem, but than after a security fix of Microsoft. http://groups.google.ca/group/DotNetDevelopment/browse_thread/thread/383d6d191831c565/02cb4f8cb67bbd5f?q=simpleworkerrequest&rnum=8&hl=en#

Solved.
For anyone else having the same problem, here is a sample:

public static void Main(string[] args)

{

MyTest mt = (MyTest)ApplicationHost.CreateApplicationHost(typeof(MyTest), "/myapp", @"c:\test");
mt.ProcessRequest();
Console.Read();

}

And than creating a new class named My:

public class MyTest : MarshalByRefObject

{

public void ProcessRequest()

{

SimpleWorkerRequest swr = new SimpleWorkerRequest("Test.aspx", string.Empty, Console.Out);
HttpRuntime.ProcessRequest(swr);

}

Build the application once and place the compiled file in a newly created bin folder in your path. So for example: c:\test\bin\ConsoleApplication1.exe in my case.

The file will be copied to the ASP.NET Tempory folder as far as I can see and then be run.

Works weird, let's see how I can get this in my application:D

Thanks.

I can't imagine this working in a medium trust environment (I could be wrong). You should be careful when breaking the barrier of medium trust, as most asp.net hosting platforms aren't dedicated and generally run as shared with medium trust per app.
