VS 2008 : Use The DHCP API To Retrieve A Computer's MAC Address When Given The IP Address?

Nov 27, 2009

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.

Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean

vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

Game Programming :: Programming Such As OOP ?

Oct 30, 2011

I avidly create games in VB.net. Being a hobby programmer I give my games away for free. Since I'm a hobbiest without formal training I do try and educate myself on proper programming principles and follow them when programming such as OOP. There are however some things I have obviously missed being self-taught that perhaps I would know if I were formally educated. Once such issue that has really been my bane is how different classes (from now on referred to as objects) 'know' about each other WITHOUT programming specific interaction.

Okay imagine this, you have a space game and the following objects

[CODE]...............

Now each one of these objects has a Health, X,Y and Z private members and properties that are all inherited from clsSpaceEntity for argument sake. Now one way of programming collision between them would be to code out the following logic in the main game loop

[CODE].........................

Now this might seam okay if your talking about the simple example above but some of my games have tens or even HUNDREDS of objects that interact in this basic way. Is there a way in OOP to do the following... for each thing that inherits from clsSpaceEntity check against every other object that inherits this type (except itself) and if they collide then reduce health next? This sort of ability for a type of objects/class or whatever to be 'aware' of another and how they are the same/different and interact would save me tonnes and tonnes and TONNES of coding.

Parallel Programming In .net 4.0

Mar 31, 2011

I have been reading up on the parallel programming and even now still a little confused on the whole concepts. Lets say I have a single project with about 5 classes that interact and have local variables in methods and variables accessible to all methods in a single class and even 1 or 2 variables accessible to all classes accessed through instantiation. Now using threads I know that global variables would be overridden by multiple threads if there were no locking applied but local variables to a method/function do not, right?

So if I ran the project multiple times meaning as a new process, the methods and variables would be thread safe right and no data corruption occurs? So to implement parallel programming using the task factory, if I created a project that basically creates tasks and each task is basically running an instance of another project, then shouldn't the variables and data be thread safe and safe from corruption? But what if I had the output files and they named by Output & datetime.now.tostring, would there be conflict issues and I ask this knowing that I have seen this happen when trying it. [Code]

Programming And The Language .net?

Oct 21, 2010

I have a general question about the programming language vb.net. I wonder how I should see the vb.net language compared to a "lower generation " language like for example C+.For example if you had to develop a CRM application , can you build such an application in both programming languages with the same amount of detail and efficiency?

Is it right if I say that the "language" vb.net is an abstract version of for a example a lower language like C+ in a way that the same possibilities are possible as with C+ but more efficient so it takes the programmer less time? So basically if you would compare it with building a house in C+ you would need to build a door with all the separate pieces while in vb.net you would just place a door as a whole. But this does not mean the possibilities of building a house as a whole are fewer.

So now comes my final question: can vb.net be seen as a true programming language like C and can somebody who masters vb.net be seen as an equally good programmer as somebody who masters C+. Or would the C+ programmer in this case be superior?

Which Softwares For VB 6.0 / 8.0 / 9.0 Programming

Jul 16, 2010

I am a new visual basic learner and I already have some difficulties in finding the proper softwares to start my first programs. I will have to develop in vb6.0 and 8.0 (.net 2005) and 9.0 (.net 2008), what softwares do i have to use? From my search, I will have to use Visual Basic 6.0, Enterprise Edition (or another edition) for 6.0 programming, right? And for 2005/2008 vb.net programming, could I use visual studio 2010 for both languages or is that better to use visual studio 2005 and 2008? Well i guess i might be a bit lost in all those different terms.

.net - Programming Readability With Strings?

Jun 22, 2011

While working on a project I have come across a way of not having to check if a string isnull or empty

dim sb as new stringbuilder
dim bob as string
sb.append((bob & string.empty).padLeft(10, " "))

Here, bob is not instantiated but doesn't throw a null reference error. In situations like this, is it more readable to do the above code or the below code?

if string.isnullorempty(bob) then
sb.append(string.empty.padleft(10, " ")
else
sb.append(bob.padleft(10," "))
endif

I personally think method #1 is more readable and maintainable.
