I'm trying to calculate the amount of CPU usage my application uses.
My code.
Try
Dim CPU As Integer = CDec(PerformanceCounter2.NextValue.ToString)
Label44.Text = CPU & "%"
[Code]...
The problem is that sometimes it says it uses more 115% hmmm.... That's when i was for sure that its lying to me.
Is there a way in VS2010 to monitor net usage, and calculate the current/total download and upload while my application is running?

this what i have so far
dim totalprice as string=""
if klant.lblprice.text >0 then
totalprice =klant.lblprice.text.count
totalbesteding.lblprice.text=totalprice
end if
does anybody has an idea how i can calculate the amount of an object so that i can get a total amount
This should calculate and display the total amount due. There are 3 radio buttons, A, B, C. Nonprofit should get a 20% discount from final charges.

I would like to use C# for an application I'm building, but the application makes heavy use of automation (i.e. Excel, Word).
Is it feasible to use C# for such an application? It used to be a nightmare to use C type languages for things like parameter lists with null arguments etc..?
How Do I get the CPU usage of my application with a PerformanceCounter?
View 3 RepliesWell there are several ways that you can implement such a log. You could write to a text file or XML file...or you could use the Windows Event log.
What do you envision using for logging purposes?
I have a small-scale WPF application using VB.net as the code behind and I want to add certain features, but i'm concerned about performance.
1) My app interacts with a third party database to display "realtime" data to the user. My proposed method is to create a background worker to query a database every 30 seconds and display the data. I query about 2,000 records all long integer type, store them in a dataset, and then use LINQ to create subsets of observable collections which the WPF controls are bound to.
Is this too intensive? how much memory am i using for 2,000 records of long int? Is the background worker querying every 30 seconds too taxing? will it crash eventually? Will it interfere with the users other daily work (excel, email, etc)?
2) If an application is constantly reading/writing from text files can that somehow be a detriment to the user if they are doing day to day work? I want the app to read/write text files, but I don't want it to somehow interfere with something else the person is doing since this app will be more of a "run in the background check it when I need to" app.
3) Is there a way to quantify how taxing a certain block of code, variable storage, or data storage will be to the end user? What is acceptable?
4) I have several list(of t) that I use as "global" lists where I can hit them from any window in my application to display data. Is there a way to quantify how much memory these lists take up? The lists range from lists of integers to lists of variables with dozens of properties. Can I somehow quantify how taxing this is on the app or the end user?

View 1 RepliesIs it possible to create an application with vb.net to track a users usage of Excel, Word and another application called lets say - Userapp.exe
At work we have been asked to create a diary of our days work and since most of my work is in excel, word and a custom application I have built, I was wondering if it was possible to track the usage of these programs store the data in a datatable and then save it to a access db.
Usage of the program would mean the time that the file is open on the screen, that way the time a program is open but minimised in the taskbar would not be counted.
The data table would have these headings -
1. Program (i.e excel, word etc.)
2. Name of File used
3. Time used in program

I am trying to write an application that monitors internet usage. So it sort of needs to act like a firewall/proxy, recording each site the computer goes to. It will record all these sites in a log file. Using a proxy server on the network is not an option, each computer running this software needs to be self sufficient. Do you have any suggestions on what to use for this project?

im trying to make a fast food program on which the user will input the amount that he has, then he will check on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I have the program somewhat finished (thanks for the people that helped me before) but theres still a couple of things that I still need to get finished but I dont know how to.I need to be able to get how much money the user has (this will be entered threw a text box, I think I accidentally messed this part up, because I cant get it to work right, (theres alreasy a permit amount of money in there and it needs to be what the user enters instead of the permit, 5.59, one) and this will be the maximum amount he can spend, then the user will check on the food he wants (and the program will add the sales tax also) then it will produce an answer saying if you have enough money or if you dont. But what im confused on is how do I get the users amount of money and make it the maximum mount he can spend and make sure it doesnt go over the amount that he has checked.[code]
View 1 RepliesI have a several C# console applications that basically parse tons of data in memory (LINQ) and output the results to a text file. Now, forget about the writing to the text file for a minute because this is not where the problem is occurring.
When I run the application in debug mode, I will never get it to utilize more than 50% of cpu usage. It will be parsing/massaging hundreds of thousands of records, but only go X fast and utilize 50% of the cpu AT MOST (as viewed in the Task Manager).
I would really like to use 100% of the CPU to make the processing go faster. Does anybody have any insight? I am running Windows XP Professional with Service Pack 3. I have Visual Studio 2008 Professional with Service Pack 1 installed. I have manually set the affinity of the process in Task Manager to a single core on the dual CPU. Sometimes I can catch it utilizing 51% or 52% of the CPU.
There is a very strange problem with a Windows Service I am working on that I would like to understand why it occurs. The service loops every 5 minutes and then within that loop it loops through keys containing webservice URLs that are numbered such as:
<add key="URL.1" value="http://dummy1.com/Service.asmx"/>
<add key="URL.2" value="http://dummy2.com/Service.asmx"/>
<add key="URL.3" value="http://dummy3.com/Service.asmx"/>
The code that does this check is:
If String.IsNullOrEmpty(AppSettings("OM." & intCount & ".Name").ToString) Then
When it hits a key that doesn't exist an exception is thrown and the service stops and waits for 5 minutes until the next loop.This usually works great but every week or two the Windows service will crash on that line without any Exception. The application log has a line from before that line but nothing after, none of the Try Catches are hit (the main one is catching the base "Exception" class).In the Event Log for Windows is the following:
Faulting application name: MyService.exe, version: 1.1.2.0, time stamp: 0x4fa22a24
Faulting module name: KERNELBASE.dll, version: 6.1.7601.17651, time stamp: 0x4e211319
Exception code: 0xe053534f
[code]....
The weird part is that this line of code is executing fine 300 times a day for at least a week which is around 2000 times before that one time it causes a full crash of the application. why this is occurring? I have changed that line of code to not rely on Exceptions and it has been working fine for a week now with no crash so could be something to do with too many Exceptions - maybe causing a stack overflow?

View 3 RepliesI would like to sleep for packetSize/Bandwidth amount of duration for a network application in VB. This value varies from "10^-3 - 10^-6" seconds.When I use the Sleep() func, I think it is not sleeping for the duration if it is less than unity (< 1 sec ~~ 0 sec??).
Edited:I have to keep sending packets after a short nap of above range. So, I could not specify, for eg., to sleep for 0.001 milli seconds at the client side.My requirement is for the client side of CS app, which reads a file and keeps sending small packets at regular or irregular interval of sleeps to the Server. The Server, later, captures the packets and processes it at its own rate..

1.I�d like to publish a free vb.net desktop application for the users to download and use meanwhile I�d like to collect usage information ex: user ip address, user�s registration information, used features, time spent� if the user allows the report to be sent back.
2.Also , in order for the user to be able to use the application, he�ll have to register it then, everytime, before the application loads, it gets verified online that it was registered, maybe validate the registration information or a valid user name and password, no critical personal information. The target of this step is for the application to be used exclusively by the registered user and maybe on his computer only.
I'm curious to know the spread level of programs coded in VB.net.I'm asking, because I coded in VB.net during my university years in aerospace engineering , because our informatics professor wanted us to do that and we learned at least a very basic experience in programming.So I coded a horizon finder as a project-work and asked a friend of mine, a student of informatics, and he really asked me if my professor wants to use this vb.net program on one of his satellites. (okay, even I don't want my program on a real satellite, even on this nano test satellite it was intended for :)). I replied, that I know, that he uses other vb.net stuff in it.he said, this vb.net is not used in real world's programmes and it is slower than other languages, and it isn't as flexible.he said, that there are other ways in crashing this satellite than using vb.net ;)
so I would like to know a rough estimation about the percentage of programs coded in vb.net as a software in PC apps AND in automation machines etc.
