Process.Start Only Starts Up To 23 Simultaneous Processes From A Service On XP?
Oct 22, 2009
I have a service that needs to run several independent processes, my problem is that it only creates up to 23, from the 24th and so on the processes are not started and a DW20.EXE window error is displayed, it only says that the there has been an unhandled exception and that the proceess is going to be closed. Inside the process.start block there is no error so I guess it could be some limitation somewhere.

i have used following code to repeat a process creation/close iteratively dim vProcessInfo as new ProcessInfo For i= 1 to 100 dim p as new Process vProcessInfo.Arguments = some"+i.toString() p.StartInfo = vProcessInfo p.Start() p.WaitForExit() p.Close() Next i the above code worked for me successfully. but it takes too much time for process creation and dispose. i had to change process argument dynamically in the iteration. is there any way to change the process argument dynamically. or is there any better method to reduce time.

The original code came from AutoItI just rewrote what was necessary for VB.NET and added the structures and throws. If successful the PID of the process started is returned, else an exception is thrown. No imports needed.

For some time ago i have notice that my App on every start make a call to csc.exe and starts it. I know for sure that that did not happened before and I can not find out why this is happening now, or better to say: what did I do in code to make this happened? I have google-it and found out that csc.exe is some kind off on-the-fly compiler for C# (If I understand it correctly ) but my App is in VB.net so I am a bit confused. Can someone explain it to me in general what have I did in my VB.NET code to make my App on every start calls csc.exe?

I have a Windows Service that needs to start other processes under a user context other than that used by the service. I've seen other posts related to this but have seen no resolutionI've tried many things and have been unsuccessful in starting the process from a Windows Service when a username, password is supplied. orking as it's a requirement of our system to do this and it worked fine until recently and only fails on Vista and Windows 7 (works on XP).
The following code is used to start the process.
Dim P As New Process
P.StartInfo.Domain = Domain

I am trying to make an application which will list all processes in a string when it starts. After it has listed them all I enable my timer, and in the timer there gets checked if the process is in the process list (string), and if it isn't it will add it to my listbox. The only problem is, it's not working, it's never adding an item.
vb.net
Public Class Form1 Dim AllProcesses As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'The first check For Each p In System.Diagnostics.Process.GetProcesses() If AllProcesses = "" Then AllProcesses = p.ProcessName Else AllProcesses += "|" + p.ProcessName End

We create a window service that will launch multiple process of an application with different configuration. And application further communicate with sql server. It works fine when we start service manually from service manager. It launch all the process ( try with launching 3 process ). But when we test it by restart the machine and service launch automatically then it launch only one process third one. I check the event log in event viewer. I see the following message by MSSQL$MSSQLEXPRESS service
Login failed for user 'dduser'. Reason: Failed to open the explicitly specified database. [CLIENT: <local machine>]
one thing we also tried by delaying ( with thread sleep ) the code execution of service. Then by starting machine again , it launch 2 process , first one still not launch.

I have a service made from VB2008. It works fine on my station and on several others. However, on some stations, I get an "Error 1067: The process terminated unexpectedly". The service includes a log writing procedure in the OnStart event but the service crashes before even getting there. This is really weird because, as I say, the service runs fine on several stations. At the moment, the service is a full-trust app, is set to logon at Local System level and has the following manifest settings:

I have created a 7 day timer in a VB form that is to be part of a larger project. It has 14 date time pickers set to hours and minutes only in 24 hour format (1 on and 1 off per day), 7 checkboxes, 7 radio buttons, 2 textboxes to display day of the week and current time and a few buttons. As a standalone project, this works well

I have ran into a small problem with my code. I got bored lately so I wanted to try a project. A program that will start up with windows starts up and it opens a webpage like google.
My code is below.
Imports System.IO
Public Class Form1

I use the code [code] System.Diagnostics.Process.Start [URL] when a button is clicked, but when I add that code in without clicking a button, it does not work. I have tried to put it everywhere, but it just does not work. I have also looked it up.

I know similar questions have been asked/answered, but after looking across the net for 2 days I still haven't really seen an answer to the following question.rst, background info: My application starts at windows start as a user checkbox option (by using the run key in the registry.) I don't know if it is usual or not, but when the app auto starts on windows start, no saved user settings show up on the form (but they do when starting the program manually after windows is already running). I've tried both HKEY_CURRENT_USER and HKEY_LOCAL_MACHINE. In case anyone needs or wants it, my code for accessing the registry is:
Dim Reg As Object
Reg = CreateObject("Wscript.shell")
Reg.RegWrite("HKEY_CURRENT_USERSOFTWAREMICROSOFTWINDOWSCURRENTVERSIONRUN" &

I'm using Process.Start to start an external command line application and using the StartInfo.Arguments method to send parameters to the application. I imagine I'll need to use a loop... but I can't figure out exactly how yet.I need to send anywhere from 1 - an infinite number of files names to this application. Each file has to be sent one after the other. So once the first one is done, I need to loop back around and past the second one.I can probably use the Directory.GetFiles method to get all of the files, but I don't know how to assign them.

I have an application (application #1) running with Administrator privileges on Windows 7.
I want application # 1 to start another application (application #2) without Administrator privileges so application #2 is running as a standard user.
Is there a way to do this? I have been using Process.Start.

Here's what I currently have:
[Code]...
I've commented out various things to limit it to specifically this command (example, I can swap mklink out with notepad and it works fine). The command runs fine from a DOS window, but can't be found when I use it this way. I also tried using the SHELL command just to test and I get the same results. No idea why it can't be found, as like I said it executes from the command prompt just fine.

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.
