Nov 26, 2011I'm making an application in which I'm implementing auto-monitor turn off when system is idle, i.e. when user is not interacting with the system. [URL]it does provides the componenent to know when system is idle. But when I include:

View 1 RepliesC# - Programmatically Reset Windows XP Idle Time
Feb 11, 2011Windows resets the IDLE time every time the user touches the keyboard or the mouse. My application needs to reset the IDLE time at specific moments, but how to do this programmatically.
The following does NOT reset the IDLE time using VB, C# or QT4.
- Programmatic mouse movement / click.
- Programmatic keystroke.
Somehow Windows knows these actions are simulated. How can I reset the IDLE time?
VS 2008 Determine Mouse Idle Time On Form?
Mar 31, 2009way to reset a timer if there is form activity so it will not expire until the mouse has been at rest for 2 minutes.
This timer runs for 120000 milliseconds usually, and sometimes it lapses (and logs you out) when you are in the middle of editing. Sometimes 2 minutes is not enough time to do all the edits. So I wish to reset the remaining interval as long as there is mouse activity. But I am not sure the best method to do this?
I have found the mousemove event but to me this seems like it's going to fire way too often and tax the resources if I preform operations here, maybe not? Is there a better way to get this functionality?
I want this functionality so that if someone starts editing on the UI and walks off/gets distracted it will lock the grids back so that some other user can't come dork things up.
VS 2008 Show Restart Form After Idle Time
Dec 28, 2009My main form has a timer that monitors idle time in my app: no mouse movements and no clicks.If the idle time reached 3 seconds, in *this example below*, then I want to show frmRestart, which will call the UnloadAllFormsExcept(Me) function from frmMain.When three idle seconds are reached, frmRepeat starts to show on the screen but never does!! I just see the border of the form and nothing else. My mouse goes into "thinking" mode forever.[code]
View 5 RepliesIdle Duration Of An Application?
May 4, 2009I have an MDI form in VB.nEt where I have to find, if the application remains idle for 20 mins, I got to log off the logged in user. On doing RnD, I found a class that helps us do the same :- http://blog.perfectapi.com/2008/05/detecting-idle-state-in-winforms-apps/
I saved that class in my applicaiton. In my mdi form's Form Load created an instance of that class. Now I don't know how to move ahead i.e. how to find that 20 min lastActivity duration. I belive I got to trap some evcent in my mdi form and find the value of lastActivity and if that is >= 20, then logoff. But which event to trap and how, I have no clue. In the events for the from also, I didn't found any useful.

Forms :: Input Starting And Ending Time
Nov 2, 2009I want to make a very small program where the user inputs a starting time and an ending time that is in "clock time (?)" and the program converts it to total minutes in one box and a decimal total in a second box. I have 4 textboxes, 2 are masked text boxes (military time) for input and two are not, for output and the math is coming out weird.
If I put a start time of 0925 and an end time of 1015, the results I'm expecting would be 50 total minutes and .83333 total as a decimal. I don't think I'm converting the textbox input correctly as I'm not getting anything near that. I am using a button to calculate and another to clear the boxes, just FYI. Also, I'm not sure what to do about any times that span the noon hour except to use an absolute value.
Public Function Time()
Dim StartTime As Double
Dim Endtime As Double
StartTime = txtStart.Text
Endtime = txtEnd.Text
txtDecimal.Text = (Endtime - StartTime) / 60
txtMinutes.Text = Endtime - StartTime
End Function

View 18 RepliesUser Input Of Time In Format Hh /mm / Possible With Datetime Picker?
Oct 13, 2009I would like to capture a start and end time in format hh:mm.Instantly I thought a datetimepicker would be the most suitable component (see code below)[code]Now I'm unable to find a datetimepicker solution to allow settings of intervals like in the numericupdown control and unable to even set a mindate/maxdate in time format. Does anyone have a solution for these requests? I then thought about using a numericupdown control to capture hh:mm time but I could not find a way of doing this in ONE control rather than two whichwould involve code to ensure only valid hours/min values could be selected i.e. 0 - 23 and 00-59 and other date to string conversion/validation.For such a commonly recorded element I'm surprised to find little in the way of solutions other than third party controls.Does anyone have ideas for a way forward for a control to capture time as hh:mm with interval controls for hours and minutes?

Capture When A Machine Is Idle?
Jan 21, 2009Is it possible to capture when a machine is idle? I realize that a machine is never really idle, but screen savers work and power management schemes work... So, there must be a way to create an application to capture the same thing, correct?

View 1 RepliesWrite A Program To Request Positive Numbers One At A Time From The User In An Input Dialog Box
May 12, 2009I'm currently in VB class at my highschool and we just got chapter 6.1 to read on this online textbook that we follow. Anyway, we are doing loops now and the problem reads "Write a program to request positive numbers one at a time from the user in an input dialog box. The user should be instructed to enter -1 after all the positive numbers have been supplied. At that time, the program should display the sum of the numbers." So far I know this much
[Code]...
Now I know this isn't right But I can't find out how I'd pull out the numbers the user entered to get the sum of them and not include -1 because as it stands, when I hit ENTER with -1 the label just shows -1.
ASP.NET -> WCF Concurrency - System Hangs And Goes Into A Idle State?

View 2 RepliesExecution Based On System Idle Status
Oct 13, 2011I am in the process of developing an application for one of my clients. I am not going into the details of the applications, but brief facts of the same. The application is divided into two tiers (actually three, but the third tier is the database (SQL SERVER) so that is not included). The top tier (or first tier) is a web application (ASP.NET) where the users shall log into the system and use the application. This web application will also access the Database directly. One important activity the users shall do is uploading excel files with various information to the server. Web Application once the upload is successful shall enter the details in the in Database about the upload along with an ID and save the excel file at a location in the server.The Second tier is a VB.NET Application which will run in the server. The application will connect the database and retrieve the list of excel file uploaded by the web application and start processing one excel file after another based on ID. The processing that will be done is very simple: read the excel file, check for certain parameters, do some calculations and insert the whole details into the database. (say some 100 records per excel file)
The server in which the VB.NET Application (Second tier) runs is hosting a serious of services and application which shall run simultaneously including the Database (SQLSERVER), web server. The Database also host tables and database for various other applications. In order to help in the smooth functioning of the system, it has been decided that the VB.NET shall do the processing activity only when the server is idle (including CPU usage is idle). I have searched the Net and found API to get the system Idle status. But the real question is how to pause the processing activity when the system switch from idle mode and continue when it is again back to idle mode. Please note that I am talking about system being idle because no other application is executing any activity except the VB.NET Application.
Low Priority Process Not Idle Although CPU Load Is High?
Mar 9, 2011I have a small problem with process priorities (Win Server 2003 Standard, 8 Core, 16GB RAM). My VB.NET 2005 program starts a process like this:
Dim WithEvents proc As New Process
Sub Main()
proc.StartInfo.FileName = "blastx.exe"[code].....
In this case, blastx.exe runs on 4 cores.I would expect that my started process is idle and has 0% CPU usage while the system is under full load (I simulate this with prime95, 8 worker threads) and only runs if there are free resources. But it generates 25% cpu load and prime95 only 75% instead of expected 0%/100%. In the task manager, I can see that my process has the lowest priority and prime95 has the normal priority.
