View 10 RepliesI am building a web crawler in .Net which executes approx 500 httpwebrequests at a time. Everything runs fine but the problem arise at some points; Looks like garbage collection thread takes over the whole application pause for a few seconds. Is there anyway that reduce the delay generated by GC.
View 1 RepliesI would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.
I am trying to make an application with a start button and a stop button on a stop watch program. These are the codes I am using but my seconds on the stop watch don't start.
Public Form Dim intSecond As Integer = 0
Form 1
Private

intSecond +=1

After I write my code and try to run the program, the seconds will not start,
vb.net application, when the user closes the last form (the code is me.close) the application looks to stop, but it is still running in taskmanager?
View 17 RepliesI have a windows forms application that has no form and it runs in the background. It using a webbrowser control to get information off the internet.The program is that when I add the event handler:webbrowser.documentcompleted the program just shuts down. If i put a message box after the event handler then it works just fine because the webrowser has time to load the document. How can I do some like console.readkey that you would do in a console application?

View 8 RepliesI believe I have found a solution! I will be continuing testing to make sure it DOES in fact work, but I'm hopeful :) I have detailed how I found the solution in EDIT THREE of the question.
For anyone wishing to know the full background behind my problem and what I have kind of tried as a result of input from this question, see this: [url]
I will be editing this frequently (>3 times a day most weekdays) as I progress my research and situation, so keep checking back if you are interested or have some information or knowledge of my issue :)
Quick Background:
I have this app I have made that can be crashed by changing my screen saver or locking my work station, and in general whenever a WM_WININICHANGE/WM_SETTINGSCHANGE message is sent to it.
If I can consistently crash my app by changing my screensaver, then SOME part of doing that is sending my app SOME kind of message (not necessarily a windows message, I mean message in the most general sense), which in turn is catastrophic to my application. Due to this, I am trying to find a way to block whatever message is causing my problem from being processed by my application. I am aware this isn't the best way to go about a solution, so you don't need to tell me. Look at the backgroung info or ask why if that bothers you (there is a good reason).

I wrote the following code to build a basic game that makes two cars race (randomgenerator) and let the user pick their bets on the end results. I've gone terribly wrong somewhere in that my cars only race halfway then get stuck behind the start line and the programme keeps repeating the beeping and the messsagebox.show and adding results to the 'incorrect' box.
The only way to terminate the application is to hit 'stop debugging'.

Option Strict On

How can I stop my application quitting until a backgroundworker has finished? Its an updater, so basically I want the form to hide until the download is finished, and then exit.I've tried to make a setting to tell the app when it is still downloading, and on form closing check this variable, but it won't work. For some reason it still quits!The update window is in a separate form to the main form, so the user clicks 'Finish', the update form closes and the main form stays open.[code]
View 5 RepliesI have written a converting program, which converts binary files to ASCII files. (VB.net 2010). I need to have a functional "stop" button on the form and I was wondering if there was a simple command to make a program stop, exit all procedures, and wait for user input on the form.
It is not feasible to multithread this application, as it frequently interfaces with the form. Currently, I have a global boolean variable which becomes true if the stop button is pressed, and I have internal loops checking to see if the variable is true. However, I don't to waste CPU on checking a variable if it's not necessary.

View 4 RepliesDoes anyone know of a way to detect recent activity in a VB.net windows forms application?
We have a retail store where users share floor computers, the application will be on each machine and require a log in before use. I am trying to find a way to automatically close the application if it has been idle for lets say 10 minutes.
I guess I could do something similar with the current windows log on session - set a gp that logs the user out after 10 minutes of inactivity - but if there is an easy, non memory intensive way to do it in vb.net i would rather use that method

View 6 RepliesI'm in the process of creating a tool that allows users to download stuff from a LAN server. The progress of the download is now being shown as a progress bar that performs a step each time a file is downloaded.
But if the file is a large file (Let's say a 2 GB file) it'll take a while before the progressbar performs a step and the user might think the tool froze up and close it. Now i'm wondering if there's a way to show the activity on the NICs installed. Something like when you open up task manager and go to the "Networking" tab. Showing it as a graph would be awesome or just a percentage is good aswell I have NO idea where I should start looking..
