What Are The Advantages Of The "Using" Keyword Other Than Showing The Coder When The Object Goes Out Of Scope

May 31, 2012

Using vb.net 2008.I have used the "Using" keyword before in C# with objects that implement iDisposable.Can you use that keyword in vb.net also? What are the advantages of the "Using" keyword other than showing the coder when the object goes out of scope.I am under the impression that the "Dispose()" function is called at the IL level when you use "Using" instead of, for examplel, calling the Dispose() in the .net code.

VS 2008 Use The New Keyword To Create Object Instance

VB is telling me to use the "NEW" keyword to create an object instance. For example: Private Sub ScoreTotal(ByVal sender..., ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged

When I run the "MainStudentScores" form and click on a student with three scores separated by the "|", it should give me a Score Total, Score Count, and Average. However it is giving me an error message at "Scores.Add(intPlaceHolder)" This is where VB is telling me to use the "NEW" keyword. Does this make sense?

VS 2010 Place 2 Hire Coder/tutor To Project?

Apr 26, 2012

I'm in college & in my part time I have been working on some automated web task apps. Just real basic stuff to automate my own personal account tasks on small social networks (not facebook!) to keep up with fan's for my 'soon to be' record label....nothing multiple accounts & it's not any kind of unsolicited spam functions. I know I could obtain most/if not all the info/code I need on this forum... I guess some people just need their hand held more than others, in order to stay focused.

Basically I've just got some things I'd like to add to my application that are above my ability & I need someone to help me out with my code. REALLY SIMPLE STUFF..like I've still yet to figure out for example:

1) How to simply pause between functions, as opposed to having to use a timer for each function. And using 1 timer to enable another timer...and so on in that fashion. Which becomes incredibly confusing & hard to edit after adding more than 3-4 timers reliant on each other LoL

2) Figuring out a way to not have to rely on 'webpage has finished loading' to move onto the next task. When many times on social networks, pages don't load properly, especially during peak hours, thus stopping the function of my web browser based application.

3) Implementing my application using a superior web browser framework. For example Gecko, or some other 3rd party browser that can perform simple tasks like filling forms, submitting them, clicking links/clicking javascript links.Right now using I.E. web browser, after my application has loaded about 75 web pages, it's using about 200mb of ram (from its initial 16mb) because of a memory leak in I.E. to which there is no solution (documented in several threads on this forum).Where in your opinion, would be a good place to look to hire a programmer/tutor for something like this? Because I am not looking for just code, but hands on, like on IM messenger/talk me through help too. I wonder if there is even a place offering services like that?

.net - Principal Advantages Of C# ?

Apr 18, 2011

What are the most important functional differences between C# and VB.NET?

C#'s edge over VB

I'm programming in VB.net because I'd former experience in VB 6.0 and I've familiar with its syntax. I know that C# is preferred by the biggest part of .net programmers. I know that C performance had superior performance against many other languages, but there is a good advantage in the same .net framework? There is a quite good reason for advicing me if should I migrate right now from VB to C#?

.net - Advantages / Disadvantages Of Using C# In The Workplace?

Jun 27, 2012

At a colleague's workplace, a decision is trying to be made about whether to use both languages in the workplace or to standardize on one? There are some VB.Net developers and some C# developers. What advantages or disadvantages would there be to using both or to using one? Edit: To clarify this question, the question is not asking the advantages of one over the other, rather what are the advantages/disadvantage of standardizing on both languages versus standardizing on one. For instance, one point could be that C#/VB.Net may have more third party tools available and hence it may make sense to standardize all developers on that language.
