I'am trying to write a program in order to obtain a screen picture for a post review of the running window that should be periodically executed with the tasks manager.
[Code]...
I am currently attempting to support a ClickOnce application that i did not write. This application is running from a scheduled task. The scheduled task points to a .application file. This had been running happily untill today when it stopped. The only thing that has changed is that the application has been executed manually by a developer by double clicking on the .application file. Since then each time the scheduled task is scheduled to run the application doesn't appear to execute. The task reports no error and the error code (0x0) given indicates it ran and completed ok.
I am not familiar with ClickOnce and am not sure when implication clicking the .application file would have had or why it has stopped running as a scheduled task. It appears to me that everything else has remained the same (i have checked it is running under the correct account etc).
Currently I have the following VB.NET code to make a screenshot of my desktop, but it only takes a picture of the active screen:
Public Function SaveScreen(ByVal theFile As String) As Boolean
Try
SendKeys.Send("%{PRTSC}")[code].....
The following code is how I execute the above function, if it makes any difference, which I don't think it does:
SaveScreen("C:Lexer_tracescreen.png")
Now, I need to be able to take a picture of the entire screen, not just the focused window.
How can you do this? I want to have my program run every once in a while but I don't want to make it a service.

TaskScheduler on Windows xp, does anyone know a API used to select a certain task to Run? or do I have to go through that darn COM ITASK interface, I think that might have a method?
View 6 RepliesI have to sync information between a users table in SQL and a user group in active directory. For example, if a user is entered into SQL table A then they need to be entered into group A and if a user is removed from SQL table A, then remove them from group A.The application is written in ASP.NET (VB)
I see two solutions:
1) A scheduled task that runs every night syncing the two (written in VB.NET).
2) Use inpersonation so that Active Directory can be updated by the ASP.NET application. The Web.Config file will have to be encrypted in this solution.
I have read articles online that say it is bad practice to update AD in ASP.NET. This would suggest that option 1 is the better solution. Which is the better solution?
Is it possible to create scheduled task with VB.NET. That is I'm trying to launch/trigger my application at specific time.
View 13 RepliesMy application needs to set up a scheduled task on installation. The task is to run my program on several triggers (related to logon events). I am wondering what is the easiest way to do this? Should I use a batch file?
View 1 RepliesI've read a few posts here on StackOverflow about task scheduling, but I'm not sure that I get it right. I'm coding (in VB.Net) a backup application, that I'd like to add as a scheduled task (in fact, I'd just like to let the user decide to run it every day at, for example, 3 AM)I've read posts suggesting to use a windows service for this, but it sounds a bit to much for something as simple as periodically running a task, isn't it?
View 2 RepliesIm am currently coding an application for auto updating ccleaner. Everything worked well until I enabled UAC.. I am using this project: [URL] to schedule the updating process, but when uac is enabled I get every time a message if I would let ccleaner installer make changes to my computer. The auto updating process must be done silently without bugging the user with prompts of uac.
When i manually check the "run with highest priviliges" box in task scheduler it does run without a prompt. But I can't seem to do this programmatically. Or I havent found it yet.
To create a scheduled class, I call the schtasks command from my code, passing it the necessary arguments.Yet, I can't really figure out how to create a task without the user having to input his password.
View 1 RepliesIs it possible for the installer or the first running of an application to create a scheduled task entry? Barring that, what is the least resource wasteful way to have a program run in the background watching the system time to run at a preset time?
View 6 Replieshow to do this off hand? I saw a few things for Microsoft.Win32 having some classes but I can't find the reference for it in 2010, which makes me think it is depreciated.
Edit: Can't find Microsoft.Win32.TaskScheduler or Microsoft.Win32.Win32_ScheduledJob which are the 2 I see suggested to use.

View 3 RepliesI have created a console application to run through the db (about 22K )records and update some values nightly. I've added an email to myself on any errors. When running the task I get about 500 emails saying:
"Overflow" (which is what's returned by : exception.Message)
What does it mean? Is it running through the db too fast?
Here is my code:
For Each dataRow As DataRow In dt.Rows
curries = 0
baseDate = Nothing
sourceID = 0

I created an exe app in vb.net and I want it to run every 3AM so I used the scheduled task feature of Windows 7. The app has an initial form that will countdown from ten before proceed to the main process. My problem is that the form doesn't poped up. But when I look at the task manager, my app is running. I don't know what's wrong with it because when I tested the app to run at times when I am viewing it, the initial form pops up. I already set everything like to Run whether user is logged on or not. So I really don't know what wrong with my app.
View 1 RepliesI have a simple vb.net application. When I go to bindebugprogram.exe and double click the program runs perfect. The same program will not execute using task scheduler. When I create a scheduled task and click 'run' it just pops up a console window for a second, closes. Additionally, this same program used to run with task scheduler. One day, it just stopped working.
ps: I have this program code managed in svn so I can safely say that the code has not changed.
how to add the creation of a scheduled task to the setup project of a solution so that it will install the main executable and also schedule it to run in windowsscheduled tasks. The project is in vb.net 2005?
View 6 RepliesI've been having huge problems having a VB.NET Windows Forms program run as a scheduled task under XP SP3. The program runs when I set the task up to use my non-admin network username and password, I can see the interface fine (albeit without the desired results - the program requires access to remote shares). When I set the task up with the network administrator account credentials, the task is "Running" but I do not see any interface. It doesn't error - it just kind of sits there happily in the background.

Changed thread type to QUESTION. I was then able to mark AS ANSWER the relevent post which now also immediately follows this post and so it is easier to find as suggested by forum user j2associates .
<edit> It is also my 3rd post in this thread, the 8th one up, of my posts, from the bottom ( for now ), as the forum format has changed yet again.I will leave the rest of this post( as is ) purely for historical reasons.

I am using VB in VS 2008. I have written a program which loads data into SQL Server nightly. It is a Windows Forms application which runs well from Task Scheduler when a user is logged in. However when I try to run it when there is no user logged in, the program starts but it just sits idle.
