Process.Start Hangs with Service

I am trying to kick of a DOS program from a VB.Net service. The
program works fine when called from a batch file, and from a Windows
form, but it has problems when called from a service. The program runs
successfully but does not give control back to the service.

After the Process.Start statement no code will execute. The program
has exited and is not shown in process monitor. I am running the
service under an admin account.

See my code below.

Thanks for any help!

Brian
Dim myProcess As New Process

myProcess.Start Info.FileName = strProcess
myProcess.Start Info.Arguments = strArguments
myProcess.Start Info.CreateNoWi ndow = True
myProcess.Start Info.WorkingDir ectory = strPath
myProcess.Start Info.UseShellEx ecute = False

Try

'Kick off the program
myProcess.Start ()

'No code after here will run!!

' wait until it exits
myProcess.WaitF orExit()

LogToFile("Conv erted File")

Catch ex As Exception

LogToFile(ex.Me ssage & " " & ex.Source)
ErrorHandler(ex .Message & " " & ex.Source)

End Try

What code do you have in your batch file? You don't wait for exit when you
exicute it.

You are running your service under admin account, but why not under
LocalSystem?

The process (console app) executes fine using the process.Start method,
doesn't it?

In your code, you are saying 'WaitForExit' & this is holding up your
application. Comment out that line & try again. Or what you can do is make
sure that the console app doesn't have any Read or ReadLine's at the end so
it does exit. That way, you will pass back function to your service.

Let me know your results

Dave,

There are in this 2 know problems.
A service is not allowed to show on screen
The user of the service should be authorised to start a proces on a certain
workstation.

I never tried this, just found this in the newsgroup.

I hope this helps?

I have a web service that needs to create a batch file and call it (since there are no APIs for the functionality I am looking for). I am using the Process and ProcessStartInfo objects.

After much frustration and aggrevation, I found that CMD IS in fact running, but it is running under the context...

Hi, I'm trying to kick off the iiscnfg.vbs from a webservice to export a website's config to an xml file (And eventually populate other servers with the config). I initially tried this using the 1.1 framework, but discovered that when I used Process.Start() the user's credentials were not impersonated, it just kept using the asp.net's user, so I switched the webservice over to 2.0 as Diagnostics.Process.StartInfo now has username,...

The following C# web service works fine until you uncomment the lines setting UserName and Password. Then the process starts as the specified user, but hangs in a suspended state. In fact, any executable will exhibit this problem; it is not specific to whoami.exe. This is with .NET 2.0, of course (1.1 does not support running a process as a different user). This appears to be a bug. Can anyone comment? <%@ WebService Language="C#"...

hello, if i start a program (an exe-file) with Process.Start(...) I don't have the required permissions that the programm needs (i could start the programm but the program needs special rights).

In the task-manager the process is created, but it doesn't do anything - no cpu-load and no change of memory-usage. What...
