I'm trying to understand how I would retrieve information about a running process on my machine from a VB.Net routine.For instance, Assume I open Task Manager and see a process called "Bob.exe".From Task manager I can see the PID for Bob.exe, the memory it uses, the I/O information, etc.I want to be able to query the machine for this information for Bob.exe from a method within VB.Net.

View 1 RepliesI have been working for some time on a service that will act as a task scheduler and perform a shutdown action at one of 3 given shutdown times. Before you cringe and ask why not use the task scheduler, I should explain that permissions do not allow users to "create" scheduled tasks and therefore a creative work-around is required. In any case, I am still new to VB, but am including my code below. I want the service to check an alarm time every minute and launch a shutdown application (in the user's context - if logged in) if that time is NOW.

Using vb.net and ASP.net
This is annoying. I'm trying to put a wrapper around some functionality that uses a web service to return some information. The intention is to wrap all of that communication into a dll such that the user can simply call functions from the dll to get back information, without needing to care about the service.As far as I can tell, that isn't possible, because the service information, as far as bindings and endpoints, HAS to exist in the app.config of the program that references the dll. That means that anybody using this dll won't just be able to add a reference to it and use it, like they would with any other kind of dll, they must also edit their app.config to add in a bunch of information. That's a simple copy and paste job, but it's incredibly unfriendly, and exposes some of the internal workings of the dll to casual inspection.

View 4 Repliesi have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

I was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods.
