Count How Long Someone Is Idle?
Jul 29, 2009
Is there a way in which I can detect how long someone has been idle using a form (ie. Not clicking or entering any information into any fields/textboxes). Or would I have to implement a timer which counts this and reset it in the event handler for any entry?

look at this code and see how i can speed it up? Its calling a sub to count commas in long string.Calling part 'Sort the incomming messages Dim count_Coma As Integer = CountCharacter(_InMessToAction, ","c)
The sub. This takes about 0.7 of a second to count 20 commas in string _InMessToAction. Was hoping to get it down to 0.1... if at all possible.

I need to find the best solution to count how long it takes to make a request to database like connect, do a select and receive the answer. And if that take more than 300 milliseconds I must cut the connection.
Public Function FindLastCt() As Decimal
FindLastCt= 0
Dim strrequete As String = "SELECT MAX(CM_Codigo) FROM CAJITAS WHERE CM_Date >= '" & Format(DateTime.Now, "dd/MM/yyyy") & " 00:00:00.000' AND CM_Date <=
'" & Format(DateTime.Now, "dd/MM/yyyy") & " 23:59:59.999'"
Using connection As DbConnection = factory.CreateConnection()

This is not useful, but:If you like Mayan culture,This code convert an integer in Mayan numericals
It can convert in the "Normal Count" system and in the "Long Count" system.In the Normal Count", every glyph is a power of 20, with the most significant on top and the less significant at the bottom
The "Long Count" system was used in Calendar. In the "Long count", every glyph is a power of 20 except the third glyph from the bottom, which is a multiple of 360. This was done because the years were, at the begining of the Mayan culture, estimated to be 360 days.Since I couldn't find a Mayan font, the function returns a bitmap that contains the drawing of the glyphs that represent the mayan numerical

In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy
Dim cursorIcon As Cursor
cursorIcon = Cursor
Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:
[Code]...
It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.

I'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:
Public WM_SYSCOMMAND As Integer = &H112
Public SC_MONITORPOWER As Integer = &Hf170
<DllImport("user32.dll")> _
[code]....
It shows this error: Cross-thread operation not valid: Control 'Form1' accessed from a thread other than the thread it was created on.

Is 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?
Has any tried this or has any success capturing when a machine is idling?

I 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.

Adding How would you detect if the user is using the computer? I want a program to detect if the user is using the computer (i.e. mouse and keyboard movements), and if the user doesn't type or move the mouse for a specific amount of time, it executes a command. Normally I would do this with the Application.Idle, but I want it to be detected throughout the system. Any starters?

I've build a vb.net windows service which does nothing but ping a wcf webservice and handles sending a maintenance request to this same webservice at night time. It does both tasks using a timer event. If the service does nothing but these two things it says at startup that it's shutting down cause of being idle. The windows service thread needs something todo.[code]....

I'm developing an Ajax-based application which makes heavy use of server calls to a WCF layer that communicates with a DB.Whenever I effect from the client (an ASP.NET page) many calls within a short span of time to the underlying WCF services, the system hangs and goes into a idle state.

Windows 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?

I 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.

I 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.

way 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.

My 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]

I have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog. I've implemented a workaround so the ReportViewer control displays the correct number of physical pages, but is there a way to get that value from the ReportViewer control? The only publicly accessible property gives the logical page count.

designing a Windows based computer program that will allow a user to enter some number (n) and a choice of a count up or count down for that many numbers. So for example, the user enters 5 as their number and selects the count down option, the message box displayed would contain the message: "Here are your numbers: 5,4,3,2,1,0"

During the RowDataBound event, retrieve the data from each column and add it to the appropriate sum. I'm not sure if you are developing an ASP.NET application or a Win-forms desktop application so I cannot help you any further at this point. What have you tried so far to solve the problem?
