Usage - .net Application In "Real World" Software?
Jan 6, 2010
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.

I am having a problem trying to get a real time back from this code.
Code:
Public Sub Time()
Dim StartTime As TimeSpan = TimeSpan.Parse(txtStart.Text)
Dim EndTime As TimeSpan = TimeSpan.Parse(txtEnd.Text)
[Code]....
I am using a start time of 09:25 and an end time of 10:15 to test this with. I would like it to return 50, as 50 real world minutes went by. I am getting -1331385.
This is mostly someone else's code from a different forum. I have never used a TimeSpan method before and they keep telling me it works "like what I asked for".

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..?

Well 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?

Is it possible to make an app (with VB.NET or any other language) that actually listens to real FM? not internet radio, or XM Radio, or any of that, but actual (Signal) FM radio, the type you listen to in a car or with a radio? if it's possible, is there any special hardware that's needed? I mean, if i wanna make it will all the consumers be able to run it? or only a selected few? Im sorry if this question is too long...
And is radio dead now or is that what people say? Am i the only one that stil listens to radio?

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.

I am starting a new project in VB, a card game modelled to be similar to a real card game.
I have the majority of the program planned out and have even started coding parts of it; my problem comes with the networking.This is a real-time card game (not turn-based) and I want to be able to play with real people (family mostly, so over LAN is what I'm after).
I have tried searching for code samples but I everything I have found seems more complicated than I feel is required for the task, introducing a lot of new concepts and not explaining them.
What I'm after is a simple way to exchange the information in real-time, I don't care so much for efficiency (at the moment) just ease of use - though if I need to wade through a heap of documentation I will. A perfect answer would tell me what the names of some of the controls/methods that would be appropriate are, even if it just re-affirms a bit of the complexity, you do not have to detail anything if you don't want to I just feel a bit at loss as to what exactly it is I am looking for!

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?

Is 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?

Does a the size of the class affect the memory usage of the application? is it better to break big classes into smaller classes or just group them up into one big class.

I 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.

We 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.

I have some very rusty C++ and lots of C experience, but have done little OO design or coding.I've started learning C++.NET as that seemed to be the best starting point.I've hit restrictions in Microsoft's provision with multiple inheritance and extensions, neither work in C++.Would I be better off starting again with C#, or am I better off using a mixed language approach. eg. extensions in C#, rest in C++?I'm still struggling with this->method or that.property and theother::staticthingy or whatever, and this probably is not an issue in C#. You'll see what I mean as that probably isn't the right way to desribe the difference between '->' '.' and '::'I'm getting to achieve what I want, but it's taking me 10 times longer than I think it should.

I have a lot of HD images within my program design and it is causing the screen to flicker when loading other forms. It is kind of
slow too. Is there a way to resolve this, for example, using a reference or component such as DirectDraw. Here are my computer
specifications:
Intel Pentium 4 /2.53GHZ
1.5 GB RAM
512 MB ATI Radeon HD 2400 PRO AGP Video card
19 IN. LCD Widescreen 1440x900 resolution monitor.
could it be the refresh rate of only 60HZ?

At the minute I can display the mouse position using Cusor.Position.ToString() but my screen resolution is widescreem - 1360:768. What about about someone with a standard 1024:768? If I use my application on other computers, it won't work because it deeply depends on mouse co-ordinates
I am aware of a world coordinate system (or something) that will work on all screen resolutions. To use this (which I will need to) I will need to change all of my coordinates in the code? So I'll need to display it in a text box like I did with Cusor.Position.ToString() but what code can I use to get the world coordinate?
There is something like PoibntToScreen and PointToClient but what do these do exactly and how do I use them? I tried using
Code:
MouseCoordinates_tssl.Text = "Mouse Coordinates: " + "{X:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).X.ToString + "; Y:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).Y.ToString + ";}"
but much to my disappointment, it didn't work. What could I do that would work?

after numerous google searches and comparing excerpts from different peoples' various codes I could not get this program to work, though I came quite close. I'm attempting to make a program that will tell me the time in different parts of the world, a personal use program that I thought would help me exercise my vb skills.
The problem I'm having, however, is that when it should be showing my time it is either 5 hours ahead or 5 hours behind. I tried adding variables and deleted them again time and time again trying to make adjustments but all I managed to do was make the timer get stuck at 12:00:00 AM.
