Running .bat file using C#

Question

Hi i've created a code that will run a .bat file on schedule test here's the code

string taskBat = @"c:\bla\bla1\test.bat
        
        TaskService ts = new TaskService();

        TimeTrigger tt = new TimeTrigger();
        tt.StartBoundary = DateTime.Now;

        tt.Enabled = true;
        tt.Repetition.Duration = TimeSpan.FromMinutes(5);
        tt.Repetition.Interval = TimeSpan.FromMinutes(1);
    
         // Create a new task definition and assign properties
        TaskDefinition td = ts.NewTask();
      
        td.Triggers.Add(tt);
        
        td.Actions.Add(new ExecAction(taskBat, null, null));
     
        string taskName = "taskName";
      
        ts.RootFolder.RegisterTaskDefinition(taskName, td,TaskCreation.Create,null, null,TaskLogonType.InteractiveToken,null);

But what happen is that , it opens the the test bat on the right time but it suddenly fails

Is there something wrong?I tried schtasks.exe and still the same ?I'm using windows server 2003  would this have cause it?

Answer 1

hi,

it "suddenly fails" is pretty vague.

Where does it fail, do you get an exception? What message do you get?

It has a dependency on a xml file in the same directory but says that it can't find it.I've tested it manually and there seems to be no problem at all with the xml file or the test bat. I'm worried that the schedule task ran fast and it's unable to find the xml file(first time using task scheduler api). Is this the only way for me to use Task Schedule?

Answer 3

hi,

sounds like your batch uses a relative path to the working directory, which may be/is different when run as a scheduled task.

What i understand from creating Task Schedule is it will create a .job  file , now since the task is created in the Windows\Tasks(just checked my task scheduler) it will never find the .xml file oui.What's the best workaround for this?Am i understanding this correctly?

Answer 5

hi,

create a simply test batch in C:\Temp\TestCD.cmd containing

@Echo Off
Cd >> C:\Test\TextCD.Result.txt

What output do you get when you run it via your job?

btw, you should post your batch, at least the relevant parts.

Hi Stefan,

 

I've replace the string in my batch file and it running now, but entered another roadblock.

The.bat file also needs to get a .config(which is a xml) file,the error is "Cannot find in C:\WINDOW\system32" yada yada this file.Now when i paste the config file into SYSTEM32 it works.

Is getting the .config file from System32 is part of Task Scheduler.I got my Task Scheduler API from Codeplex.

 

@@echo off

@rem "Filter Syntax : /f:include Type:Automation and 

gallio.echo /working-directory:. /rt:MonsterReport D:\aaa\bbb\ccc\something.gallio

@@echo on

Do i need to do something inside the .bat file so that it can find the .config file

This is what I told you: The batch is running using another working directory. The easiest solution would be the use of an hard-coded working directory.

Do i need to do something inside the .bat file so that it can find the .config file

Post your failing batch...

Answer 8

Set the ExecAction's WorkingDirectory to the bat's directory.

Answer 9

Hi All,

 

I was able to solve the issue by inserting the working directory like so

string dir = d:\foldera\folderb\folderc\foldere 
td.Actions.Add(new ExecAction(taskBat, null, dir));

The task scheduler API from codeplex support this and my program is running fine

Thanks for all your help, really appreciate it
