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.
[Code]...
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.
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

View 12 RepliesI'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

View 10 RepliesI 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?
How would I make a VB program that can "wait" for a process to start and then kill it?
View 8 RepliesI'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?
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]

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.
View 4 RepliesI'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?

While navigating to a series of sites at one site the WebBrowser control's DocumentCompleted EVENT is tripped and no other recorded Browser events occur after that. When this happens the hour glass cursor indicates the browser is waiting. From this point it take 120 to 250 seconds of wall clock time before the browser resumes. I am looking for a way to force an abnormal termination without destroying the control. I have tried "Stop", "nav to about:blank" repeatedly without success. How can I force an abnormal termination when the Cntrl is in a wait state?
Consider the following: The last known Browser event to be tripped is a Document Complete event; nothing else occurs after this. When this transpires the Cntrl is waiting.

I'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
View 9 RepliesNow I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

View 5 RepliesI have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).
