VS 2008 CPU Usage Increasing Over Time?
Jun 19, 2009
I am currently running through a loop with 20 threads. These loops contain a series of 3 HTTPWebRequests (relatively CPU intensive). At the beginning, CPU usage never spiked above 10%. After about 7 hours of run time, CPU is spiking up to over 40%. I believe that this will eventually lead to the program crashing (it has before in less time, I modified some things and it seems to be running longer). What kind of intense CPU spikes are associated with threading? More importantly, how can the duration of runtime affect CPU usage by so much?

I'm building a VB.NET 2010 app that tracks battery usage. Run the app, start logging, then let the battery go flat. At the end, you get a nice graph that shows you how long the battery took to run down. Compare it to previous results and you can see how battery life is doing.
But this is supposed to be an unattended app, so it's not feasible for me to sit down and use word, browse the Internet, listen to music, play games etc. for four hours (especially at work!), so I'm looking for a way to artificially increase CPU usage to chew through the battery faster, and simulate how a battery would probably be used throughout a work day.
I've managed to inflate the memory usage using:
Dim a as long
Dim ptr(0 To 20000) As IntPtr
For a = 1 To 20000
[Code]....
I increase CPU usage in VB.NET? I've tried creating new threads with constant loops, but I get the funny feeling that VB.NET optimizes these kind of things to prevent memory and CPU hogging apps from taking over

I'm having an unusual problem that I've never had with WR's before. I have a very user-driven program that interacts with a server of mine through webrequests. Depending on what the user's doing, it could end up sending a dozen requests/minute. This has never been a problem before, but for some reason system memory usage increases and doesn't stop increasing, as if something is cluttering it up for every webrequest that is sent out.
Is there a known problem with WR's like this? Or is it just a random screw up? I can get my system back up and running smoothly.

I am making my project for this semester. I am making "System monitoring Tool" so i have make a GUI and also get the all parameters but one thing missing I have tried to find from different places but not found that is the "continues line" that represents the changing values of CPU usage along time. same like "windows task manager" shows.

I am new to arraylist. I have used standard 2 dimension or single dimension arrays which is there is .net & legacy VB.What I want is removing & searching in arrays to be easy ? VB.net does provide something called arraylist whereby we can remove items easily like X.removeat (index) or x.remove (search) etc.[code]Now I have a array person. To add i do redim person(10) or using preserve if I need to dynamically add etc. To remove is a pain as I need to copy contents and remove manually.Anyways in .net you have option called ArrayList.How can I use this to make life easier? If I want an arraywhereby I can do person.removeat (2) or person.add person.name="XYZ" & so on.Just wanna ease up on searching & removing.

Im wondering if there is some way of monitoring individual processes (read: not mine) cpu usage and ending (asking politely then killing it off) the offending process. I dont know about you, but i've been in multiple instances where i've been unable to get to taskmanager to "choose" process to be killed. For multiple reasons (Either taskmanager has been visible, but a game window is still showing (alt+tab not working), leading to a guess game of clicking processes or cpu usage has been so high that one mouseclick takes 30 sec.)

Im trying to monitor the battery of notebooks to diagnose whether there charging/discharging correctly or not for my work. I can get the basic info using SystemInformation.PowerStatus but i want to be able to see the slope or decline of the charging via a graph. Is this possible? i was playing with the system monitor control and thats the kind of output im trying to get. A simple line graph would be perfect....passmarks battery test is a example of what im going for

101
102
103... to infinity

I have a small page, with a button on it. When I click the button I'd like the code to look at a a field (call the field "InvoiceNumber") in a table (call it "InvoiceTable"), take the last number stored, increment it by "1" then store it back in the "InvoiceTable" and display the new invoice number on the page.Currently the button is called "New Invoice", so clicking this button is going to create a new invoice, with a number one newer than the latest one in the table.

Why did they choose to add a new keyword AndAlso, instead of just changing the functionality of the existing And keyword?
Why would one want to use And, instead of AndAlso anyway?
Is it not just increasing the number of keywords unnecessarily?

I placed a button on my form that measured 59mm in width (approx 2.25 inches for any Americans).When you run the project as you'd expect it still measures 59mm.However when I set the form as a child to my MDIParent and run the project the button now measures 67mm (well over 2.5 inches) an increase of 13.5%.Is this a bug or do I need to just change some setting somewhere?

I am struggling to do what i want with classes at the moment as they are killed off at the end of a method, can somebody let me know how to make the classes live until i tell them to die? so that i can create one and refer to it from another method at another time? For example On form load i create a class Dog.Then later on i want to get info from the Class Dog. But it is no longer instantiated

I'm guessing the reason this macro isn't doing what I want it to is because of an error on my part in the code. Basically, I want the values in the cells pointed out in the code to be increased by 10% each time the button is pushed.
Here is the code:
Sub Add10percent()
IncreaseColumnValuesBy10Percent 2, 0.1
IncreaseColumnValuesBy10Percent 4, 0.1
IncreaseColumnValuesBy10Percent 6, 0.1
IncreaseColumnValuesBy10Percent 8, 0.1

My application has 1 main form and three other forms which raise events to my main form. I noticed that the memory starts at 77,000 K and increases substationally over a few hours maby be to 250,000k and ever increases.The main form has a dataset and a bound datagridview which gets refreshed with data. Basically it's a taxi booking application. The booking form raises an event to the main form and the main form refreshes the jobs and displays them on the dgv.

I'm attempting to have my page automatically scroll to the top when there is an error message to present to the user. Following a tip I found searching, I've enclosed the Javascript scrollTo function in a setTimeout function to avoid a conflict with AJAX remembering the scroll position. Here is the relevant [code]....
This is working fine for me locally, but when I move the code up to our test server, it does not seem to take effect.I have tried increasing the length of the timeout, but no dice.
