C# - Kill Process Started With System.Diagnostic.Process.Start("FileName")
Oct 2, 2010
I am trying to create an app that will perform actions on specific times (much like the Windows Task Scheduler). I am currently using Process.Start() to lunch the file (or exe) required by the task. I am initiating a process by calling a file (an .mp3) and the process starts WMP (since it is the default application), so far so good. Now I wan't to kill that process. I know that it is normal behavior for the Process.Start(string, string) to return nothing (null in C#) in this case. So I am asking how can i close WMP when I called it through Process.Start(string, string)??

My app starts an On-Screen Keyboard process like this:
Dim PID as System.Diagnostics.Process
:
PID = Process.Start("C:WindowsSystem32osk.exe")
:
[CODE]...
It seems to work 90% of the time. However, sometimes the PID.Kill() fails because it says the process already exited. At this point the OSK is always still there on screen. Yes, I know my code should be testing to see if the process is still running before trying to kill it, but given that the OSK is still on screen..

i use System.Diagnostics.Process.Start to run a process
example :
Dim p As New System.Diagnostics.Process
p = System.Diagnostics.Process.Start("D:ProjectApplication.exe")
it works perfectly during run time. but after i deploy to server.... this code did nothing, it did not call out this process

Cannot start a process because a filename has not been provided.
Private Sub Backup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdBackup.Click
Process.Start(adbFind.adbLocation.Text, "pull /data/local/bootanimation.zip C:Backup.zip")
End Sub
It was working fine now this is just started to appear, i have went back as far as i can where i only have that line of code and it still appears.

I am trying to kill process using following code
Dim ItemProcess() As Process = Process.GetProcessesByName("vlc")
If Not ItemProcess Is Nothing Then
For Each SubProcess As Process In ItemProcess[code]....
Now I have created two sub in the first sub I started a process using process.start(preview.mp3)in the second sub I killed this process using the above code but instead of passing the mp3 file I am using the vlc.exe which is actually processing the fileFor this I have to manually check the task manager and get the process name.So my point is ,is there any way i can write a code that automatically the corresponding exe file that is using it.

I 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).

How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code:
Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read)
Dim sr As IO.StreamReader = New IO.StreamReader(fs1)
sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.

I am working with saving and deleting images. What i really want to do is check and see if an image exists in the destination folder and if it does automatically overwrite it. i couldnt figure that out so i figured i would look to see if the file was there if it is Delete it then write the new file..The issue is i keep getting this error.The process cannot access the file "FileName" because it is being used by another process.

Is it possible to use system.diagnostics.process.start("Process.exe")But the process would not be seen by the user? For example, I want to play an audio in the background using windows media player, the audio will play but wmp won't be visible. Is it possible?

I am attempting to make a piece of software that monitors a 3rd party process for injected code. I successfully made a program that uses readprocessmemory from kernel32 to search for strings in a process. My problem is that the process I am attempting to monitor is running as system and provides an access denied message when I attempt to query any information about the process. Including process.handle and process.modules. Are there any ways I can get this process' handle?

My VB.NET Windows form application includes a BackgroundWorker that calls a command-line batch file in a Systems.Diagnostics.Process object, which in turn calls a Java command. If the user cancels, the program kills the cmd.exe properly via process.kill() (it is ok in this case), but the java.exe child process remains, which makes the program hang. I've researched how to kill a parent and child process. It seems there are complicated ways to do this via WMI or Win32 API. But I'm hoping there is a simpler VB.NET way.

I'm using VB.NET for a web-application that starts some process using CreateObject, like this:
Dim AVObject = CreateObject("avwin.application")
After all is done everything get closed down en stopped using the proper release functions, however, for some reason the process remains.
Is there some way in which I can get the process id of the started process, in order to explicitly kill it just before termination?

I have a program that starts another program after setting the regkeys basically the program continually syncs the calandar of outlook and another application.I set the regkeys than launch the c:sync.exe app. I have tried a simple process.start and launching the process as a thread and they both do the same thing: The other process starts and works as it should but my main program goes "White screen" or "not responding" until the process.start has exited.
I want the process.start to run in the background so if users click in my main app it responds and truly that they can access the context menu of my main app from the taskbar while the process.start is running.

I'm having a problem. I have researched this for over a week and have not found what I need. I find a lot of great suggestions but none of them work for me.My code and program works 100% if you put a valid program, process or file name in the box but if you don't, it crashes. Also if the program is not registered or in a known path it will crash.
I've tried My.Computer.FileSystem.FileExists(txtProcessName.Text) and System.IO.File.Exists(txtProcessName.Text)
But every variation I try thinks that none of the files exist.I don't want to hard code any of the paths or file names because I want this to be dynamic. I also want it to be a one file program. I know eventually I will need to get into multiple files but I like basing all my programs on a file that can be copied and pasted to any computer and ran without problems.
NOTE: This is a multi-function program. Not only does it start programs but it also terminates them, looks the process up on the web to see if it's spyware, adware or a valid program and it also is a Task manager.

I'm using System.Diagnostics.Process.Start to open a file using a string stored in a SQL datatable. It works absolutely fine as long as there is an application on the local machine associated with the file type. If there isn't an association, what happens is the "Save as" dialog box pops up. What I'd like to happen is to just bring up a message box or some other prompt that tells the user what the problem is, and to contact the helpdesk. Some users will be confused if they see a "Save as" dialog box, I think.

I'm doing, well trying anyway, a calculator that is well fitted for "us analogue/HAM Radio enthusiasts", with basic AC and DC formulas, and a search-engine.... And it's this search-engine that gives me a darn head-ace!I placed a TextBox object at the bottom of the form, and first I just had a Button and a Label, saying "try google?". And a LinkLabel and a Process.Start method.
Dim search As String
LinkLabel.LinkVisited = false
search = TextBoxSearch.Text
System.Diagnostic.Process.Start("IExplorer.exe", "http:google.com/", search)
And I then got in my head that it would be cool if I could add a second TextBox object and the user could simply type in the search-term and when the Process.Starter called i.e. IE6/7/8... would open google, and displayed the result of the search on google, in the browser..But how ever I try, I get only a browser to start with google's url or exception error, though I have a try/catch method ...What I want to achieve is a "google toolbar" on my calculator, I haven't yet learned how to use VB script and it's probably that which fault me..

I am using a System.Diagnostics.Process to execute dirquota.exe. I catch an exception at .Start() which is "The system cannot find the file specified".
I am now doing:
foreach (var fi in new DirectoryInfo(@"C:WindowsSystem32").GetFiles())
{
Console.WriteLine(fi.Name);
}
This outputs pretty much every file in that directory apart from dirquota.exe.

java.exe -jar MyApp.jar pathToSourceFile pathToDestFile
How do I run this command in VB.Net, using System.Diagnostics.Process.Start, assuming I have the following three string variables in VB.Net

I have a vb.net 2008 application that is supposed to run at startup. After meeting certain conditions, the PC is supposed to restart. Below is the code that is failing:
System.Diagnostics.Process.Start("shutdown", "-r -t 00 -f", myUsername, myPassword, myDomain)
myUsername and myDomain are both strings while myPassword is a SecureString. The application works properly when execute manually, but give the following error when executed from startup (either by placing in the startup folder or by adding to the registry):
The directory name is invalid
Also, the program executes properly when the last 3 arguments are left out and the user has the necessary rights.
How do I force a restart using an specific, alternate user credentials on startup?
