I have scheduled a Windows task using this command:
SchTasks /Create /SC MINUTE /mo 1 /TN PWSchedule /TR "C:\Program Files\Implant Sciences\B220\patches\batch\SanminaTaskSchedular.exe" /F
This is a batch file which creates a task and runs an .exe file.
The .exe file is a C# Windows Form Application which changes stuff in the database.
My problem is that I see multiple instances of Task Scheduler running in the taskbar/process. Does anyone know what is going on here?
/SC MINUTE means the task will be scheduled by every minute. If you want your task to be scheduled only once, you should use /SC ONCE.

I am attempting to run a batch file that utilizes the VMWare VIX API and VMRun.exe to power on/off virtual machines in VMWare Workstation. Currently my batch files work correctly when run from the command prompt. However, I can not successfully execute them from my Windows Service built in C# & .NET. I executed my batch files in my service in the following way:
string myBatchFile = ConfigurationManager.AppSettings.Get("MyBatchFile");
System.Diagnostics.ProcessStartInfo processBat = new System.Diagnostics.ProcessStartInfo(myBatchFile);
processBat.WindowStyle = ProcessWindowStyle.Normal;
processBat.ErrorDialog = true;
Process.Start(processBat);
I have been able to run a simple batch file that creates a text document from the service. The code for this batch file looks like this:
#echo off
echo Hello World>"C:\Users\MyPC\Documents\HelloWorld.txt"
This works as expected when executed by my Windows Service.
When I try to execute my VMWare batch file I am unsuccessful, and can not find any way to check log my output or debug it. My code for this batch file looks like this:
#echo off
set LOGFILE=batch.log
call :LOG > %LOGFILE%
exit /B
:LOG
cd "C:\PROGRA~2\VMware\VMWARE~2\"
vmrun.exe -T ws Start "C:\Users\MyPC\Documents\Virtual Machines\VM1\VM1.vmx"
PAUSE
I attempted to add a way for a log file to be created but nothing gets generated when I execute the batch file from the service. Any guidance would be greatly appreciated, thank you.
All the solutions I can find on this topic are very old and none of them appear to answer my question...
I am trying to create a windows service that can self update (or auto update by some external trigger). In the past, I had created a windows service that was installed with InstallShield and we were able to update auto update the service in a hacky way by making the service write a batch script to the local machine and then run the batch script, which would stop the service, overwrite the service executable and other files with the new ones, and restart the service. This surprisingly worked.
However, I have updated the service to use InstallUtil.exe and this auto update script no longer works... I assume it's something to do with the way InstallShield handles the service install vs how InstallUtil does it... but I can only make guesses as I don't fully understand what each is doing to the registry.
Since I can't just overwrite the files and restart the service with the InstallUtil method, I thought I'd write a batch script that runs sc.exe to stop the service, uninstall it entirely, write the new files, install the new service files, and then start it... unfortunately, I can't seem to get sc.exe to run from a windows service automatically because it requires admin permissions... I tried to force it to self-elevate to admin using this snippet, but it doesn't appear to work as a service (it works fine if I run it from command line not as a service)
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)
Does anyone know how I can cause a windows service to self update? I can look into updating to a .NET Core Worker service if there is some method of self update in .NET Core that I'm unaware of... Any ideas are much appreciated... it really shouldn't be this hard to accomplish...
For reference, here is the batch script I am currently using (ignore odd variables and such as I am dynamically replacing some of them, it works great when launched manually, just doesn't work when the service tries to run it):
#echo off
setlocal enableextensions enabledelayedexpansion
::make sure to run whole script as admin (this restarts scripts as admin if not already in admin mode)
if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b)
pushd %networkDirectory%
::stop running service
for /F "tokens=3 delims=: " %%H in ('sc query %serviceName% ^| findstr " STATE"') do (
if /I "%%H" NEQ "STOPPED" (
net stop %serviceName%
if errorlevel 1 goto :stop
)
::delete existing service after stopping
sc delete %serviceName%
)
:: install updated service files
set "releaseDir=%networkDirectory%\Release"
set "programFilesCopyDir=%ProgramFiles%\{_companyDirectory}\%serviceName%\Release"
:: copy service Release dir to local system program files
xcopy "%releaseDir%" "%programFilesCopyDir%" /S /Y /Q
::execute the install
pushd "%programFilesCopyDir%"
CALL %serviceName%.exe --install
::start service
sc start %serviceName%
For anyone else trying to accomplish this that stumbles on this... I ended up finding a solution. I use the same script posted in my question above, but I wrote code to set up a scheduled task with Windows Task Scheduler. The scheduled task runs the above script as a one time scheduled task. This works like a charm.
I used this NuGet package to write the Task Scheduler code I needed:

I have a c# code that installs rabbitmq 3.7.4, erlang 20.2 on windows server 2012 R2 and I need to know when the application (not the service) has started. After running rabbitmq-service install and rabbitmq-service start I'm looking for a command line that will indicate that the application is running. I'm aware of the wait pid_file, wait --pid pid command but can't locate the pid file on my machine. The documantaion says:
This command will wait for the RabbitMQ application to start at the node. It will wait for the pid file to be created if pidfile is specified
specified where?
rabbitmq-echopid.bat returns:
The system cannot find the path specified.
On Windows, RabbitMQ does not create a PID file by default, so you have to discover the PID and then pass it as an argument: rabbitmqctl.bat wait -P PID
To discover the PID, you can run the following using the name of your RabbitMQ node:
.\rabbitmq-echopid.bat rabbit#my-hostname
At this time, there is a bug where The system cannot find... will be echoed before the PID is echoed. I filed this bug and will have a fix in soon, but in the meantime you can edit the rabbitmq-echopid.bat script to change !TDP0! to %TDP0%.
You can also use any other Windows tool to find the PID of the erl.exe process running RabbitMQ - see the script for an example of wmic.exe, or you could use tasklist, or Powershell, etc.
On windows, you can run the following batch script:
START /B rabbitmq-server
START /wait cmd /c "rabbitmq-echopid.bat -n rabbit#`hostname` > rabbitmq_pid.txt"
set /p PID=<rabbitmq_pid.txt
echo %PID%
del rabbitmq_pid.txt
cmd /c "rabbitmqctl wait -P %PID%"
Note that for the rabbitmq-echopid command to work, you have to add an -n before the nodename.
Moreover, in the above batch script, the nodename is dynamically generated by combining "rabbit#" withe the hostname windows command (inside backticks).
I have a .NET console application written in C# (myApp.exe), that runs an external application ('bob.exe'). The console application works great when I run myApp.exe manually. The C# code that calls the application is:
System.Diagnostics.ProcessStartInfo procStartInfo =
new System.Diagnostics.ProcessStartInfo("C:\\bob.exe");
procStartInfo.RedirectStandardOutput = true;
procStartInfo.UseShellExecute = false;
// Do not create the black window.
procStartInfo.CreateNoWindow = true;
// Create the process and assign its ProcessStartInfo and start it
System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo = procStartInfo;
proc.Start();
In Windows Server 2003, I created a Scheduled Task that executed 'myApp.exe' on a regular basis. It was set to execute even if the user was not logged in. The Scheduled Task worked and called 'bob.exe' (I was able to verify this by viewing the output files from 'bob.exe')
We then upgraded to Windows Server 2012. I created a Scheduled Task in Windows Server 2012, setting it to execute even if the user was not logged in and configuring it for Windows Server 2003.
I set the Action to call 'C:\myApp.exe', similar to how I had it set up in Windows Server 2003
When the scheduled tasks executes and I am logged in, the 'bob.exe' application is executed from 'myApp.exe'. However, when I am not logged in and the scheduled task executes, 'myApp.exe' is executed but 'bob.exe' is never executed (I can verify this by seeing there are no output files from 'bob.exe'). There are no errors reported by the Scheduled Task and the Last Run Result says "The operation completed successfully. (0x0)".
I found a similar post here but I was unable to resolve my situation. What am I missing?
I had a similar issue with my app calling out 7za.exe to archive db backups. When I ran my app manually it worked fine, but when I scheduled my app via Task Scheduler, the 7z routine would not fire off and didn't give my app a verbose error. I found that adding the directory I ran my app from to the task scheduler's Start in (optional): box corrected my issue.
Program/script: "C:\Program Files (x86)\CustApp\CustApp.exe"
Start in (optional) C:\Program Files (x86)\CustApp\
Note not to use double-quotes on the "Start in (optional)" setting for the directory, it errors when I did.
I had a similar problem with running a Batch file (on WS2008) and the problem was due to the permissions given to the user executing the scheduled task on the folders where the Batch file and the Executable files were set.
I'm not sure if the security of WS 2012 is different, but if I were You I'll try to debug the application (if you have the code) checking for permissions.

I have a little .exe written in c# .net that I want to run on the server every 24 hours. So naturally I would just use the Windows Task Schedular rather then doing the math myself. I have created the program, but I would like to create an installer that just set everything up. Is there a way to do this with like the Visual Studio set-up projects? If not is there like a powershell / batch script that could be used to run after installation?
Bottom Line: Automate the creation of the task.
You can use a powershell script or batch file to execute schtasks which is a command line interface to the task scheduler.
Then you simply need to run the script in order to setup the scheduled task.
There is also a managed wrapper that allows you to create schedules tasks in C#, if you would rather go that way.
I know this is an old question, but I figure this may help someone else:
You can use the following to run in cmd.exe
FOR /F %1 IN ("path to text file containing list of servers") do psexec.exe \\%1 -u
"username to execute schtasks under" -p "password" schtasks /Create /S %1
/RU "username that will run the task" /RP "password" /XML "xml file of
the task to install" /TN "name of the task"
This will loop through the list of servers in a text file (1 server per line) and use psexec to call schtasks on each server and install your task.
