Another process property to be aware of is the WorkingDirectory property set via StartInfo which sets the directory that a process will be started in.

This can be important when the program you are launching assumes a certain working directory e. How about checking if a process is currently running? The code below demonstrates how to achieve this. The ProcessIsRunning method accepts the name of the process to check as a parameter. The GetProcessesByName method on the Process class is used to get an array of Process objects which match the specified process name.
The KillProcess method accepts the name of the process to stop as a parameter, as well as a timeout parameter which configures how long the method will wait for a process to stop before giving up. After getting an array of Process objects, the code iterates through the array and ignores the current process, as per the ProcessIsRunning method. For all other processes matching the specified process name, the Kill method of the Process object is used to stop the process.
The WaitForExit method is then used to ensure that the process has stopped successfully. Before returning to the caller, the HasExited property is inspected and an appropriate log message is recorded.

Creating wrapper methods to hide the low-level details of interacting with processes can help to make our code much cleaner and avoid code duplication.

If the list is too long, try putting it in a DIV with overflow set to auto. Alternatively, you can try using a GridView with a template column for the checkbox. Fill dsView1, "ConfTbl" ; adp. Fill dsView2, "ConfTbl" ; adp. Dispose ; dsView. Re: how to combine two dataset to one xml file Wendelius Aug Not quite sure what you're asking, but Before writing the results to an XML file, have you tried merging the datasets?
Need help with error checking for Dns. GetHostEntry turbosupramk3 Aug I have a few lab domains that are not trusted with our primary domains, but through the IP or FQDN, I can still map from the non trusted domains with proper credentials. My problem is that when I run a sessionmanager program I want, it fails when trying to query the hostname from the IP I'm having trouble writing error checking for this so I can skip this part of the code, if the return value comes back as a socket error of "no such host found", does anyone have any ideas on how to code for this return value.
An example of it failing would be MessageBox. Show Dns. GetHostEntry session["ComputerName"]. HostName ; will give a return value of "No such host found" and also cause the program to bomb. Any help would be appreciated, thank you.

Re: Need help with error checking for Dns. GetHostEntry [modified] Shameel Aug Will this work? GetHostEntry session[ " ComputerName" ]. ToString ; if entry! Hi, Thank you for the reply. That did work although the catch from your snippet still has "No such host found" and then it just continues on through the code. I've never done that before, but as long as that is ok I'm happy! Thank you. GetHostEntry Shameel Aug I did it on purpose. The only executable code within the try block is the call to the GetHostEntry method.

If the method throws an exception, it still means that the host was not found. Great, I will use this technique from now on Thanks again!

Exited event also causes the event to be fired immediately, without the process having exited HasExited works correctly Worked correctly in 4. So WaitForExit returning immediately false is the expected behaviour. I will still investigate the Exited event being fired. Can you check if the test case reproduce on your machine, or provide a repro?
Thank you. EnableRaisingEvents needs to be called otherwise the event is never fired after subscribing, calling it before event subscription races with the subscription because its fired almost?
