Whats happening is I run the code below and get the following error "The system cannot find the file specified". I've read that with UseShellExecute set to false that you can't use WorkingDirectory.
Dim Password As String = "password"
Dim SecureStringPassword As New System.Security.SecureString

I'm trying to execute a 3rd party application, called from a .cmd batch file, called from a self-hosted WCF service. Like this:
WCF --> .cmd --> 3rd party app
For whatever reason, using the Shell command doesn't work fully. It will call the .cmd file, but the 3rd party app won't kick off (I know the .cmd is firing because I have before/after ECHO statements populating a log file). If I double-click the .cmd file from explorer, the 3rd party app will start just fine. So, I figured, maybe try something besides the Shell command from my WCF service.
So I tried the following code, but it won't kick off the .cmd file at all (echo statements not firing). What am I missing here?
Dim psi As New ProcessStartInfo("cmd.exe", "/C " & System.Configuration.ConfigurationManager.AppSettings("ExStream_CMD_File_Path"))
Dim proc As New Process()
proc.StartInfo = psi
proc.Start()
proc.WaitForExit()
The path in the app.config file is valid (just double-checked). Is there anything wrong with the above code?
This is simple to explain, i need to track the process id from the files I execute. So lets look at the code.For this example just create 2 files in the C: and call it 1.xlsx and 2.xlsxNow open the firts file ...
Dim objFileExecute As New System.Diagnostics.Process
objFileExecute = Process.Start("C:1.xlsx")
MsgBox(objFileExecute.Id)

Trying to create a button that when clicked will check to see if a certain process image is running and if that process is running give the process focus. If the process is not running then start the application.
View 9 RepliesMy 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 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.
the below code starts the correct process but the windows form never displays on the remote machine. How do I get the application to actually load.
Private Sub RunRemoteProcess()
Dim sCmd As String = "C:Program FilesInternet ExplorerIEXPLORE.EXE " & txtData.Text.Trim

How would I go about starting a new process without it being the child of the calling process.
Example:
Main Program (Caller.exe)
process.start("file.exe")
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
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)??

I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

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 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).

I've been using 'Process.Start()' for awhile now, to open web pages. And now, recently, I've noticed that it does not work anymore.

View 6 RepliesI'm trying to open any file using Process.Start, but every time I try to open a file that isn't an executable the program crashes... This is the code I'm currently using:

For Each lvi As ListViewItem In ListView1.SelectedItems
Process.Start(path & "" & lvi.Text)
Next
End Sub
Path is a string that contains the selected folder path, and lvi is the text of the list view item (each item contains the icon and name of each file). It is working fine for .exe files, I was just wondering if it's JUST for .exe files...
I want to add a scheduled task like this: Dim myProc As Process myProc = Process.Start("at", "02:00 /every:T,W,Th,F,Sa c:ackup.bat") When I type that command at a command prompt it returns "Added a new job with ID = x". How do I get this ID in my code, as it's needed if I want to delete the scheduled job? I've tried looking at some of the properties of myProc but haven't found the right one yet. Maybe I need to wait until the process has completed? (If so, how will I know?).
