Visual Basic :: Task Scheduler

Task Scheduler
Background:
I'm in the process of developing a task scheduler at work. This application runs on a dedicated workstation. It simply displays the time, incrementing every second. Every second it is also checking an ini file to see if it should call another application or run a backup.

Example:
At 6:00 every day run BlockedReport.exe
At 17:30 every day backup TestDatabase.mdb

I want to make this so it takes up the least amount of system resources. The algorithm I'm thinking of using is this:

First off check to see if seconds = 00. This will ensure that the function is only ran once a minute instead of 60 times a minute.
If it is = 00, then check to see if the task should be run on this day.
If it should be run, then check to see if it should be run at this time.

Here is some sample code (I know that it isn't exactly what I said above yet):

VB Code:
Private Sub tmr_TimerFired() Dim x As Integer, iCount As IntegerDim results() As String lblTime.Caption = Format(Time, "h:mm:ss") Call ini.GetSections(INIFile, results()) iCount = UBound(results()) + 1 For x = 1 To iCount If Format(ini.GetSettingINI(INIFile, "Task" & x, "Time"), "h:mm:ss") = Format(Time, "h:mm:ss") Then Select Case ini.GetSettingINI(INIFile, "Task" & x, "Status") Case 1 'Status 1 = Execute File If ini.GetSettingINI(INIFile, "Task" & x, "Params", "None") = "None" Then hyp.File Me.hwnd, ini.GetSettingINI(INIFile, "Task" & x, "Path") Else hyp.File Me.hwnd, ini.GetSettingINI(INIFile, "Task" & x, "Path"), ini.GetSettingINI(INIFile, "Task" & x, "Params") End If Case 2 'Status 2 = Backup File Call Backup(x) Case 3 'Status 3 = Backup and Compact DB Call Backup(x) Call CompactDatabase(x) End Select End If Next x If Format(Time, "n") Mod 15 = 0 Then If y = 0 Then Call WriteMem y = 1 Else y = 0 End If End Sub

Does anyone have any suggestions, comments, critisims, ideas on how I could do this better?? If you need any more information, just ask. Any help is appreciated.

Thanks,

Mike

VB With Task Scheduler
I have been told that Mathew Gates or Megatron PM are good in that:

how can i use task scheduler with VB?
i want the user inside my application to have the choice to run the program himself each day, or to CHECK AN OPTION INSIDE THE PROGRAM (but how to program it???) that lets the scheduler run the program the next day for example, without any intervention
thanks

Task Scheduler Win98
For video capture and sound recording I have written a VB6 program. This program consists actually two programs, 1- TimerSetCap, 2 – TimerCaption. In the TimerSetCap I can select Video or Sound recording/capture and I give the duration of the recording. These values are stored in a data file. From the TimerSetCap prog I start the Win98 Task Scheduler and make the settings for the starting time. At this moment I can switch my computer in Standby modus.
At the given time the Task Scheduler starts the computer and the second program, the TimerCaption which reads the data from the data file and the caption starts for the given time. So far OK.
I like to combine the Task Scheduler in my TimerSetCap program, so I can set all values in one Form.
Questions:
A – Is there a possibility to reach the data of the Task Scheduler and change them. Windows Explorer do not find the *.job (TimerCaption.job) file.
B – Is there an API available which can change Text in a TextBox (Class Name: SysDateTimePick32) of a program which is called with the VB Shell function.

Opening Task Scheduler

Mail And Task Scheduler
I have a program that is launched by Scheduler on an NT4 server (with Outlook 2000). Outlook only uses one profile and scheduler is set to logon with the UserId that owns that exchange account. The problem is that whenever the program is launched via the scheduler it gives the following error:

"MAPI Failure: valid session ID does not exist"

However, if I run the program while physically logged onto the box it works great.

The logon code that I am using is:

Private Function LogOn() As Boolean

Dim Result As String
Dim HFile As Long

If MapSess.NewSession Then
LogOn = False
Exit Function
End If

On Error GoTo errLogInFail

With MapSess
' Set DownLoadMail to False to prevent immediate download.
.DownLoadMail = False
.UserName = "MS Exchange Settings"
.LogonUI = True ' Use the underlying email system's logon UI.
.SignOn ' Signon method.
' If successful, return True
LogOn = True
' Set NewSession to True and set0
' variable flag to true
.NewSession = True
bNewSession = .NewSession
MapMess.SessionID = .SessionID ' You must set this before continuing.
End With
Exit Function

errLogInFail:
HFile = FreeFile
Open "C:error.log" For Append Access Write Shared As HFile
Write #HFile, Error
Close HFile
Err = 0
Resume Next

End Function

If anyone has any suggestions it would be greatly appreciated. I need to get this thing working and am getting frustrated!

Thanks!

How To Add Prog. In Task Scheduler?????
I want my prog. to mail at some predefined schedule... so i want my vb prog. to add itself to task scheduler (at time of installation of prog.) ..... plz help me........

Exposing Task Scheduler API
Hi Folks,

I'm already declaring NetScheduleJobAdd Lib "netapi32.dll" on my application so I can schedule an ActiveX.exe component for later execution. However, I'm finding that the Task Scheduler cannot run the task because the username and password is missing from the job (Win2000 and VB6). I don't see a way to set uname and passwd from the netapi32 library. Is there some other library with the the function I need that can be referenced by VB6? Or I am I going to have to do something with Sleep or Timer?

Thanks,

Troy

Scheduling A Non-interactive With NT Task Scheduler
Hi,
I've been using the following code to schedule tasks with the NT scheduler. I've noticed that the function in this code only schedules interactive tasks and I want to schedule non-interactive tasks. I notice the Const "JOB_NONINTERACTIVE = &H10" and wonder if this has anything to do with how the task is scheduled. Can anyone help?
Thanks very much

Add Application To Windows Task Scheduler From VB6
We have developed an application in VB6 (say AA.exe). We wish to
schedule the execution of this application (AA.exe) through Windows
Task Scheduler.

Is there a way through which we can add this application (AA.exe) to
Task Scheduler by using another application (say BB.exe), which is
also developed using VB6? The operating systems can be Windows 2000,
Windows XP or any later version of Windows...

We also wish that whenever the second application (BB.exe) would run
it should always check the scheduling of first application (AA.exe) in
Task Scheduler and if it finds that someone has disabled its (AA.exe)
execution or removed it, then it should be added to Task Scheduler
again.

A reference to any sample available in VB6 will be highly appreciated.

Thanks & Regards

What Is The Difference Task Scheduler And NT Service

Urgent!!!!! Placed In Task Scheduler But Not Running As Expected!
Hi everyone,

I've placed my working application in the Windows Task Scheduler to run it at a certain time interval. Though my application executes at the assigned time, its status on the Task Scheduler is always displayed as "Running", it seems to me that the program is running non-stop. However, everything works well when I manually execute the application, it runs correctly and unloads within a minute.

Can anyone tell me why is this so? How am I able to resolve it? Besides placing in the Task Scheduler, is there other ways that I can run my program automatically at any particular time?

Thank you very much.

Internet Transfer Control && Task Scheduler

Is The Windows Task Scheduler An ActiveX Control And If So How Can I

Error 70 Using ActiveX Server With Task Scheduler
This is long winded so bear with...

I am using task scheduler to run an app that makes calls to an ActiveX server. The activeX server opens a connection to a SQL DB, then reads data into a recordset from one of the tables of the DB. At the point that I touch one of the items of the recordset the server pops with ERROR 70.

Worth noting: I can run this app from the desktop and no errors occur.
The DB login uses SQL authentication.

Any ideas?

WinAT Mentions that: AT jobs will NOT run under the security context of the user requesting it. Rather, they will run in whatever context the Schedule service is running, typically the operating system's context.
Which begs the question: What is the OS's security context? and is this related to my problem?

Drive Mapping In WinServer 2003 Task Scheduler
Ok... I have a VB6 utility that uses a lot of FSO objects and freeware Zip/UnZip DLLs.

Because the mapped drive is pointed to a folder, there are all sorts of issues with folders, especially inside the Zips!

What this thing does is read file data (working storage), converts it to a corporate standard, zips it, and uploads it to a SQL Server 2000 dbms.

I have server side batch processes and workstation side realtime processes.

My file structure is:

P:MainData<serialnumber>Test <Date> <Time>Test Files

Now, because P: is mapped to D:Apps, the zips are getting <server>AppsMainData<serialnumber>Test Data <Date> <Time>Test Files... this wrecks havoc when I have to restore things to the mapped P:.

Well... from what I can figure, SQL Server Agent won't look at mapped drives, and neither will Task Scheduler.

Am I correct in this assessment?

Changing the map from P: = D:Apps to P: = D: is out of the question, there are multiple apps out there that use P: = D:Apps. I have suggested the use of a second mapped drive so that my applications can use them, and that might be the easiest fix.

I am looking at PKWare's Software Kit, which has DLLs for Zip/Unzip. Do you all think that using the command line version in a shell would be more reliable?

What is happening is thus:

When I run these jobs from my computer against the mapped P:, all is fine.

When I run these jobs on the server against the mapped P:, all is fine.

When I run these jobs from Task Scheduler with the mapped P:, all hell breaks loose!

Thanks in advance!

How To Create A Job In Task Scheduler With Specific Interval (repeat Time)?
Hi,

How to create a job in task scheduler with specific interval (repeat time)?

Upon visiting numerous sites I could manage to create a task for required time.

Const WED = 4
Const THU = 8
Const FRI = 16
Const SAT = 32
Const SUN = 64

strComputer = "."
strCommand = "c:TestLog.exe"
strstartTime = "********233000.000000-000"
boolRepeat = True
intWeekDay = MON Or TUE Or WED Or THU Or FRI Or SAT Or SUN
intMonthDay = ""
boolInteract = True

Set objWMI = GetObject("winmgmts:\" & strComputer & "")
Set objNewTask = objWMI.Get("Win32_ScheduledJob")
intRC = objNewTask.Create(strCommand, _
strstartTime, _
boolRepeat, _
intWeekDay, _
intMonthDay, _
boolInteract, _
intJobID)

Now I want this task to execute every 30 minutes upto 11 PM.

How to do it?

Please help. Any sort of help is appreciated.

DOes that make sense? Would be this be extremely hard to do? Im not very experienced and wonder if this is over my head. I'm willing to do the work so if you guys got any pointers / ideas about how I might go about it, I would appriciate it.
