.net - Create Remote Process Via WMI And Wait For It To Exit?
Jan 18, 2012
I'm using System.Management to start a process on a remote target via WMI like this:
InputParameters("CommandLine") = "executable here"
OutputParameters = ManagementClass.InvokeMethod("Create", InputParameters, Nothing)
This kicks off the process and my code continues to run, but I need a way of monitoring that process and not doing anything else until it finishes. Is there a simple solution? I'm hoping there's something similar to Process.WaitForExit like there is when creating a local process.

I'm having a problem with using the system.diagnostic.process. Basically, I can't get the myProcess.WaitForExit to work. I keep getting an error saying that "No process is associated with this object.". I'm not sure what I'm doing wrong.

What I want to know is if there is a way to NOT wait for a process when using impersonation. There's no overloads so I'm not sure how to do this.
// always waits for exit to continue
Impersonation.RunProcess(someProcessPath);
The reason I want to do this is that I have a long executing application that processes large files, but I want to deliver a success response to the client that the process has began before directing them to a status page. I cannot run the process with a normal process.Start() because the IUSER needs to impersonate an elevated user account.I've even tried using process.StartInfo after Impersonation.Login() and supplying a un/pass, but I think the "logged in" status is part of the static Impersonation class only.
if (Impersonation.Logon(LoginCredentials.UserName, LoginCredentials.Password))
{
// this fails with an invalid privileges exit code

I'm having issues with a progressbar. I've created a progressbar that reads registry variables and uses that input to update the progressbar and some status messages (so I can call it from vbscripts, etc). I want it so when my status bar hits 100%, the bar stops, waits a few seconds, and then quits. However, it seems the program processes the remaining code and quits the application before it has time to completely repaint the progress bar (I'm guessing this because it will usually update to about 10% before it exits).. I'm using something like this...
If prcnt = 100 Then
progbar.Style = ProgressBarStyle.Blocks
progbar.Value = 0

I am struggling a lot with this code I am trying to get to work. I have successfully made a connection with the TcpClient object to two separate remote machines and transmitted data to them. Essentially, I'm trying to connect to Machine 1 on port 80 and send a GET request. Once I send the request I want to keep the connection alive so that the software on the other side can send me data when it is ready. How do I keep the connection open and read data in each time it is made available in the stream? I have tried and tried using NetworkStream.Read and BeginRead to no avail. The closest I have come was sleeping my thread every 30 seconds and then doing another GET request which is not needed. Here is the current code I have for reading from the stream. I know I need a loop in here somewhere:Note: RemoteSocket is my TcpClient object that is connected by this point
Dim serverStream As NetworkStream = RemoteSocket.GetStream()
rqst = "GET /Control/Clip_Forwarding_Stream?CameraName=" & URL_Encode(Name) & " HTTP/1.0" & vbCrLf & vbCrLf

I know how to launch a file or executable in VB .NET 2005. The file will launch and execution in the code continues immediately.
Process.Start("MyProg.exe")
But what if I need to start the program, wait until it finishes executing, read the exit code that it sends back, and take some action based upon the action code? How do I do that?

I'd like to have a function in my program that waits for a process to start, and once it does, it executes the code. Id like to have a form of 'buttonless messages box' or 'splash screen' waiting saying "waiting for process to start..." and once the process starts, a message box will pop up saying "Process has started!".
I was thinking of having a timer with a low delay constantly looping to see if the process exists, but that would be a little rough on the processor, no? Also, how would I accomplish the 'buttonless messagebox' that automatically closes once the process is found?

I'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).

The following code opens a Word doc and fills the data as designed. When I exit from it, the WINWORD.EXE process keeps active. If I execute the code a second time and exit from it again, a second process of WINWORD.EXE gets added and stays active. The example shown at url... doesn't produce the same problem. Obviously I'm not exiting the code as I should but I fail to see where.[code]

Basically, I am just trying to close the thread/process after it's done.
Private psi As ProcessStartInfo
Private cmd As Process
Public Delegate Sub InvokeWithString(ByVal text As String)
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim psi As New ProcessStartInfo("m7.bat")
[Code] .....
I am trying to close the thread so once it's done, it closed for good and my form is closed as well. I tried Me.Close() which results in: "Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on." Error.
Me.Invoke(New InvokeWithString(AddressOf CloseME), e) - Results in parameter mismatch error.
However, things like Msgbox("Done") works perfectly.

I am working on a game launcher, and I need to display a "Splash screen" until the main game has started. For this, I need to know whether or not the Process has a Main window that is fully loaded and displayed.Now I noticed the main window handle is 0 when there is none, so I tried to use that:[code]But the handle never becomes nonzero. I tried to use the title but to no avail.I do not want to go into "Thread.wait()" since then the splash would remain even if the game is already launched.

I'm not asking how to exit the program( dispose() ) instead I have a program that checks if a certain process is running and if so it displays a message box, stops the process and (Should) exit the program. If the process is not detected then the program loads normally and opens an external program. My problem is that it stops the process and still runs the program. How can I fully stop the code and exit my program?

I am writing a program that looks for a particular exe running on the stations on the same workgroup, if it finds it then it will kill it. I know how to look for running processes on the local pc but can not figure out how to do it on a remote pc. I am able shell("TASKKILL /S computername /F /IM exe") which works, however I do not have error logging. If there is an error the application just hangs.

copy a file to a remote target where UNC connections TO the target might not be possible.However UNC connections FROM the target and BACK to the server will always be possible. So the plan was to use WMI to start a remote command shell (cmd) and use the copy command to grab the file. But this doesn't work. The following command works fine when executed manually from the command line of the target:

In VBScript, to create a new process on a remote machine, you could use this

I would like to do the same thing in .net using WMI, and I tried to do this on my own, but my code is not working properly. If I specify my logon credentials, the process will execute on the remote machine and the code works fine, but I want the program to send the WMI query by using impersonation. I believed this was supposed to send the user credentials of the user using the program to the remote WMI provider on the remote machine. Here is the code I am using:

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 ?
