Apr 20, 2009I'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.
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.
Idle 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.

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?
Has any tried this or has any success capturing when a machine is idling?
Count How Long Someone Is Idle?
Jul 29, 2009Is 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?

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?

View 2 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?
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.
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.

View 5 RepliesApplication Does Not Return From Call To System.Windows.Forms.Application.DoEvents?
Aug 2, 2011I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me
doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?

View 6 RepliesVS 2008 Make One Application Send A Task To Another Application / Receive Result From That Secondary App?
Apr 26, 2010is it possible to make one application send a task to another application and recieve the result from that secondary app?i made a text editor program and i added a scan feature and i made another app that has ocr capabilities.The scanner ability is in my text editor program, the ocr program doesnt scan you have to input an image into it and it will give text result a few seconds later.the prob is alot of times the ocr code uses sooo much memory and crashes when its incorporated with my text editor, but individually each application works fine and doesnt take too much memory. Memory wont be even an issue if the ocr program is standalone so that when it is done decoding image the application can be made to exit. now here is the question, how do i make my text editor send the image to the ocr program and how do i make my ocr program send the text back to my text editor? is it possible? i mean the only way i know off is creating temp files in a certain folder and having a timer on each program that keeps waiting for temp files. That just seems like pretty lame coding to me i was wondering if there's a better way?
