Problem with process..

[john20]

Hi All,

I am using process class to do some processing with the files and close the process.

it works fine but the problem is it is emptying all the session value which i am assiging before running the process.

Below is the Code:

Dim myProcess As Process = New Process()
                Dim sArguments As String = sProductID & " " & Chr(34) & sLicenseFile & Chr(34) & " " & Chr(34) & sApplicationPath & "metaconfig.txt" & Chr(34)
                Dim sFileName As String = Chr(34) & sApplicationPath & "license.exe" & Chr(34)
 
 
                myProcess.StartInfo.FileName = sFileName
                myProcess.StartInfo.Arguments = sArguments
                myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
                myProcess.StartInfo.CreateNoWindow = True
                myProcess.Start()
                myProcess.WaitForExit(1000)
 
                If Not myProcess.HasExited Then
                    myProcess.Kill()
                End If
 
                myProcess.Close()
                myProcess = Nothing
 
                System.Threading.Thread.Sleep(1000) 

how to solve this problem. can u tell me any solution.

Thanks

-John

You are calling the .WaitForExit() method before you try to close it, it seems. Well, the .WaitForExit() method is to be called after the .Kill() method

Quote from MSDN
Note:

The Kill method executes asynchronously. After calling the Kill method, call the WaitForExit method to wait for the process to exit, or check the HasExited property to determine if the process has exited.

So, just try the Process.Kill() first, and then the Process.WaitForExit(). without the .close() or anything and just try that. Also, please use CODE[#] tags, when posting with more than a line of code. Please take the time to read the Posting Guidelines. And let me know if that works for you...

Hi Joedeene,

Thanks for your reply.
Tried above solution but didn't help.
Is there any other way to solve this problem.

Thanks

What session values are you refering to? I don't see any in the code you posted?
What is the actual problem?

Thanks for your reply.

In the page load i am calling above function and assiging value to session variable.
like Session("Valid") = "True"

after loading this page i am redirecting the page to another page and there i am checking the session value but it is showing empty value.

Thanks again

That is normally a browser issue, or an issue of code flow not being what you think it is.

The webpages are on the same application though yes?

Yes pages are on the same application.

What exactly does the relatable code look like?
I am guessing that your browser is just not sending the session value (security settings rejecting it), but its possible the Session value never gets set in the first place.
