I need to check if the explorer.exe process is running on a remote computer to verify that there is a user logged on the computer. I Also want to get the Process Owner of the explorer.exe process to check which user is logged on. I have found some VBscript examples online, but i can't seem to get them to work. If anyone knows of a better way of checking if and what user is logged on to a computer, please give me a reply also. I have tried System.Diagnostics.Process.GetProcesses, but i can't seem to get the owner of the process, maybe WMI will do the trick ?
View 8 RepliesI'm trying to develop a windows application where i can get connected to remote server and look for process state going in remote server.We have many remote servers where automatic installation of software going on. We have an xml file(installstatus.xml) where it tells us at what stage the installation is (Example : Inprogress , Completed, Failed.)
So our aim is to develop a windows application where i can get connected to that servers and look for their installation status(may be we can use installstatus.xml to look for installation status). Every time i connect to a server, the server information should get stored in XML file(i want to create a xml file where all the servers list i connect to should get stored)
The UI at left side should will have list of servers i can connect to. When i get connected to server, at right side of UI, i want to display the status of installation (In progress, failed , completed).
I am trying to make a vb.net program which will perform WMI queries to check for remote computer's name and OS. I manage to do the first query of name using the code below..
[Code]...
I am getting error "Local variable 'query' is already declared in the current block. (BC30288)".I understand that I am using same name for the object variable for performing subsequent query. Is there a way in which I can dispose the variable completely and reuse it again for querying the new required WMI detail? My search in the net couldn't give me any clue as of how to clear the variable and use it again. The issue is with two variables "query" and "searcher". Is it only possible that I should give unique names to each query object variable as I might add more queries later on?

I have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,
So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?
My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.

i have a task to create a TCP Server (a program that is listening on its network card interfaces for incoming data stream).I have search on the internet and i found that i can use two methods : Socket or TCPListener class.I have created an example for Socket class, but i wondering how could i test it? I need to check that if another computer in the network send some string data to the listener computer , then this message should be displayed.Here is the example from microsoft that i am using for TCP Server using Socket:
Public Shared Sub Main()
' Data buffer for incoming data.
Dim data = nothingc[code]....
But it does not work because of the PORT setting.If in the TCP Server i have "Dim localEndPoint As New IPEndPoint(ipAddress, 0)" the client crashes, but if i change the port from any (0) to 11000 for example,the client works fine.Do you know why?
Later edit2:Maybe i should have started with this question:Which method is recommended for my scope?asynchronous or synchronous method ?
