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..?
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 created a heavy application in vb.net 2005. And on start up of main form it doing lot of things like
1. Check New Software Update taking 15sec
2. Check Registration taking 15 Sec
3. Initialize Software also take almost 20 sec
First my application show Splash Screen and do 2 operations like
1. Check Update
2. Registration
So i want to do this First show Splash Screen and
-same time it start 3rd Process and remain Hide Main Form
-Same time it perform 1st and 2nd operation if pass then just show 3rd step without time waist.
I do it with delegates threading but it is not doing both operations same time.
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'm trying to calculate the amount of CPU usage my application uses.
My code.
Try
Dim CPU As Integer = CDec(PerformanceCounter2.NextValue.ToString)

The problem is that sometimes it says it uses more 115% hmmm.... That's when i was for sure that its lying to me.
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
Could I use the windows task manager for this?
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?

View 2 RepliesI love to experiment with linqpad, but now my task requires heavy computing power. Trying to do it on my computer is painful. My friend has a much more powerful computer than I -- can I execute some operations from my linqpad on his computer? I don't have RDP access, but I can run any .NET program on his computer.
If it is not possible, then is there any FREE service that provides computing power? Maybe a hosting trial or something. I know that Windows Azure offers a 30-day trial, but it has a very slow CPU module and in my country, MS partners cannot be expected to fix service sites when they go down.
I have this application that fetches huge chunks of data from databases and i would like to have a loading screen, or simple image (gif) appearing on top while the app is working... but what normally happens is the whole application locks up. How can I make a certain part of my application still responsive while the rest loads?
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.

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.

View 1 RepliesWe have a .net win forms application, using .net 3.5. Application runs from a terminal server, users access it with Citrix client. when users run this app memory usage goes higher and hiher and it never comes back. even tough we put objects with dispose and set to nothing also the memory usage is not comming down. it starts wuth 75 mb and goes up to 500 mb. it is a 32 bit application.
how can we find the exact problem with the application. the bahaviour is almost same when we run our development box locally.
Let's say you have a user class. When the user is logged in there are properties representing basic user info, an associated address and, say, 5 profile pictures, the last a generic lsit like this: Private _photos As List(Of Photo). However, instead of carrying the weight of the profile pictures in a session vairable, to reduce resource usage, I only want to populate them if the user needs to acces them. So, for the most part, the generic list of photo's is empty. Will it carry weight anyway? I'm trying to decide if I should just not populate ituntil needed, or if I should create an alternative "light" user class which doesn't have this property.
