Reference Structure Element By Element Name?
Jun 7, 2011I want to be able to reference an element in an array of structures by the name of the element in a visual basic 2010 function. For example
Public Structure myStruct
Public element1 as string
Public element2 as integer

Is it possible to reference a structures element by the element's name in a similar way to that shown above. The code shown above does not work, as the expression obj(i).[elementName] does not work as hoped.

Structure Containing An Array Element?
Jul 7, 2009I am writing a class and room scheduling program, and would like to use an arraylist that will contain structures. The structure has a couple of arrays in it for when the class meets, and I am having difficulties figuring out the correct syntax to declare the array in the structure. Additionally, in the syntax to access the array. For instance, say I want the MeetingDays to be T, F, T, F, F, F, F; the Meeting Times to be "8:00AM", "", "8:00AM". "", "", "", "", ""; and the Duration to be 75, 0, 75, 0, 0, 0, 0

Bind A Text Box To A Structure Element?
Feb 6, 2011I would like to bind the text field of a textbox to an element in an instance of a structure that I've created in a class module. When I try to create a Data Source using an OBJECT type, all I see in the tree is the name of the structure, not the instance I've created. If I select the structure anyway, the Data Sources tree does show the name of the structure and the element I'm interested in. How do I bind to a specific instance?

Asp.net - Element 'system.webServer' Has Invalid Child Element 'rewrite'?
Feb 14, 2012I have a number of rewrite rules for a lot of things that I did in IIS7, like removing trailing slashes, canonnical URLs, lowercase lettering, and such. IIS altered my web.config, and everything works fine on the website, like it should. But in the Visual Studio web.config, the opening < rewrite > statement is underlined in blue, and at the bottom of VS, it says that the element 'system.webServer' has invalid child element 'rewrite'. But this is how IIS made it. I didn't do this manually. Should I be concerned with this VS error, or should I just leave as be, since it's working how it should work? Here's an example of my web.config:

Feb 21, 2012I have been doing well and also I am a noob I know it and you know it a lot has started making sense and I am evening figuring new things out without using Google but of course I have hit another snag in my program so here goes
I am waiting for an email to arrive (the page automatically refreshes) and then I want to click the link (I do not need to click to open the email or anything like that) I also have the code to click and navigate to the address reason being it was the only way I could figure out how to stop it opening in a new window on IE
So my only problem is I need a way to check every x seconds for the element and then if its there proceed with my code and if its not wait and then check again or however this is done in VB.If this is not the way its done please point me in the right direction the code I am using to find and then navigate to the link is

Class Structure - Large Structure That Has Lots Of Properties ?
Jan 5, 2010I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.
Converting Structure Within Structure To Byte Array For Socket
Aug 29, 2009I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.

Asp.net - See If The Value Of An Element Is In A List?
Nov 26, 2010[Code]...
Now I find myself needing to do both Foo() and Bar() if value is "7" - is there a simple way to do this with an If condition?
[Code]...
I don't want to have to declare & initialize two lists if I can avoid it. Edit: I should have mentioned that this is a simplified example - there are actually a dozen or so CASE statements, and Foo() and Bar() are actually placeholders for quite a bit more code - it's seeing the same block of code repeated over and over that got me thinking about a better way to do it.
