Belk -- This message, which was originally sent to "aspngbeta", has been moved to "aspngescalate" mailing list by the List Master -- Hello, I am trying to use the ServiceController.ExecuteCommand(Integer) / ServiceBase.OnCustomCommand(Integer) methods to communicate with a Windows Service that I wrote. The OnCustomCommand receives the appropriate command identifier (in this case, 128), but I can't figure a way to return any kind of information back to the calling program. It's like the service is cut off from communicating back to the outside world. I have tried returning data by throwing an ApplicationException with my return data as the message of the exception, but that doesn't work, or at least I can't get at the information. There are no Win32Exceptions, InvalidOperationExceptions, or general Exceptions being thrown by the service, since I am catching those as well as the desired ApplicationException. Is there some other way to accomplish this? Any help would be appreciated. The MSDN library documentation is pretty sparse, as is the literature I can find in other sources.

In case you missed it, the gist of what I was saying in the message is that you probably aren't going to be able to do it, because it wasn't intended for inter-process communication of that nature, in fact, the custom command functionality isn't recommended for use from what I understand. In order to build your own interface to the service, try doing remoting over the HTTP channel with a SOAP formatter. The SDK documentation go through this better than I could, so take a look at the following URL for more information and an example (watch for wrapping): http://localhost/QuickStart/howto/default.aspx?url=/quickstart/howto/doc /Remoting/firstserver.aspx Once you have done that, you can build a client for it. The best way to do that in my opinion is to get the system to build a prototype for you, take a look at the SOAPSUDS command. More information on this is available in the SDK documentation. If you post some of your code I can probably give you a more concete example of how to approach it (post to me privately if it is easier). I did some crude testing and I managed to saw through about 1000 requests in 11 seconds. Thats not bad. ---------------------------------------- - Mitch Denny - http://www.warbyte.com - Click here to reveal e-mail address - +61 (414) 610-141 - [Original message clipped] Reply to this message...     System.ApplicationException System.ServiceProcess.ServiceBase System.ServiceProcess.ServiceController Ad MBR BootFX Best-of-breed application framework for .NET projects, developed by Matthew Baxter-Reynolds and MBR IT
