Hi;

I seem to crash (or break) VC when I execute the below code..

        
Dim c As New VisualCronAPI.Connection
Dim connection As New VisualCronAPI.Connection With {.ConnectionType = VisualCronAPI.Connection.ConnectionT.Remote, .Address = "smallappstest", .Port = 16444, .UseADLogon = True}
Dim Client As New VisualCronAPI.Client
Dim MyServer As VisualCronAPI.Server = Client.Connect(connection, True)
Dim Job As New JobClass With {.Name = "Test3", .TimeOut = New TimeOutClass With {.Minutes = 5, .Use = True, .ConsiderError = True}}
Dim Tasks2 As New TaskClass
Tasks2.Name = "Taskname"
Job.Tasks.Add(Tasks2)
MyServer.Jobs.Add(Job)

VC is returning the below after about 10 sec

System.ArgumentNullException: Value cannot be null.
Parameter name: key
at System.Collections.Generic.Dictionary`2.FindEntry(TKey key)
at System.Collections.Generic.Dictionary`2.ContainsKey(TKey key)
at VisualCronAPI.Jobs.Contains(String strJobId)
at frmMain2.LGOFIHDBKKNMKLGKEDAMKMHJDNAHAMGLGILI(Server& , JobClass , TaskClass ) in C:\sourcefiles\code\VisualCron\Main\frmMain2.vb:line 1935

I have added / removed / imported / generally playing around / so I am wondering if there could be a relation?

Upon VC restart, the application will display the same error again.

And also... does my code seem to be correct??

Thanks, Martin

Hi Martin,

and from which line is this error comming?
Looks to me that you did not fill in all the required parameters to create a job.

Regards,
Erik

Sounds like the problem is about the Task. Try replacing:

Dim Tasks2 As TaskClass = Job.NewTask

Hi;

The error is not coming from any line at all. The code executes fine and completes with no warning.

After about 15 sec VisualCron returns the error message.

I am reinstalling VisualCron again as I could not connect to the service from client or remote server.

I'll try with the suggested code as well..


Dim Tasks2 As TaskClass = Job.NewTask

This is definitely related to the Task not having the correct JobId. Your original code failed but after making my suggestions it succeeds. Here is the full code:

        Dim c As New VisualCronAPI.Connection
        Dim connection As New VisualCronAPI.Connection With {.ConnectionType = VisualCronAPI.Connection.ConnectionT.Remote, .Address = "localhost", .Port = 16444, .UseADLogon = False}
        Dim Client As New VisualCronAPI.Client
        Dim MyServer As VisualCronAPI.Server = Client.Connect(connection, True)
        Dim Job As New JobClass With {.Name = "Test3", .TimeOut = New TimeOutClass With {.Minutes = 5, .Use = True, .ConsiderError = True}}
        Dim Tasks2 As TaskClass = Job.NewTask(TaskClass.TaskT.Execute)
        Tasks2.Name = "Taskname"
        Job.Tasks.Add(Tasks2)
        MyServer.Jobs.Add(Job)

Hi.

Thanks for your help. I am pretty sure this was related to the wrong job-id.

I have removed and reinstalled. All is working now.

Thanks,
Martin
