I am writing a scripting language which used .net for execution. Now I have written a function which accepts an object and return a set of numeric values. I wanted user to pass any numeric array (e.g. integer,single,double,long) and I could return values in that format. I mean user can retrieve value in any numeric array type rather than specifying an array type. E.g.

Okay, I will be using Username &'Type' through out my project to verify certain things. On workbook open, I grab the username. Now I want to put the username list and type into a public array. The username list has a range name of UID and the type has a range name of UIDType. The combined list has a range name UIDCo. Which will be more 'resource' friendly? To load UID into one array and UIDType in another or to load the UIDCo into one all encompassing array? I will very rarely use either list alone, it will almost always be a combination of UID and Type verification.
2nd question is, I've only really used 1 dimensional array's before, any help on where I can research more about multi-dimensional arrays. I can pretty much figure out the what it does and how to use them. I'd be more interested in the actual syntax or coding samples.

I have a program which connects to an FTP server. my program needs to retreive the directory list of the server. I am doing this in the style of an OpenfileDialog control. now I can get all the information and fill the listview control. however the function I use to fill the listview control with the directory listing and file listing, returns a list(of string)
Because of this I can't determine if a file is a file and if a folder is a folder. I myself know which of them are because while getting the directorylists I check for a string value of D which means directory. if it doesn't have a D then it's a file.

Is there a way to set a textbox in vb such that it does not accept a space or a non-numeric character entered by a user? I am writing a program that has a textbox called "phoneField" in which the user should type in only numbers and if the user trys to type a non-numeric character or space, nothing should be displayed in the textbox. How could that be done?

I recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]

I have one user that is having a problem with my application, the error report shows an event type of clr203r and an index out of range exception. From what I've read this seems to have "something" to do with arrays or lists. (What that something is, so far, is beyond me or anything I've researched). I do have one array in my program -- myarray(13) as byte and I do have the syntax right as far as noting 20 elements in it. in my other bits of code.
I'm reading those bytes in the serial port, deciphering them and performing some actions. (to be vague). But just with what I've said, can anyone point me to a possible problem? Is the index out of range exception ALWAYS concerned with just arrays or lists? Or could it be something else?
I have an object that I know was originally declared was an enum, but I need tothe specificnum type. I'm aware of the GetType method and it appears to work correctly, but I can't figure out how to go from there to a direct type comparison For reference types, you can use Typeof(object1) Is Class1, but this doesn't seem to work for value types.

I'm using vb.net 2008 edition and i was wondering if there a way to convert an array type to another array type. For instance say i dim an array as string and then want to convert the array to the integer data type for sorting, how would i go about this?
View 1 Replieswrote a procedure that accepts as input a parameter of type decimal, or type Long as well as an array type ar() as Boolean. First thing I will do in the procedure is establish just what type of parameter I received. No problem with the scalar types, I'll use the .GetType,determine whether it's Long of Decimal, and assign the parameter I just received to a variable of that type by using convert.toInt64 or convert.toDecimal, then do what I need to do. Not so if the parameter I received happens to be an array. .GetType will tell me what it is, for example returns "system.int64[]" if its an array of Longs, but then I fail to assign it to a variable for further processing as there appears to be no conversion method to do that.

The details are not relevant, but for this function I need to return an one-dimensional Array containing values of the same type the original multidimensional Array has.To pass any Array with any dimension to my function, I declared the type of this parameter as Array. However, how would I create a new Array of that specific type (e.g. Integer)?Currently I have the following code:

I usually always use enummerations as a pass ID of some type with a calculated value using the n^2 notation to calculate the return values. It's easy to derive with squareroots what values are derived from a sum; but most of the time I use the Identifier String to denote a combo box drop down list view. I think this is fairly routine for most developers; since in all my coding or rework I have seen it used commonly by other developers also.
Anyway, I wanted to do some sort of comparisson array of strings to fill the combobox using the *.Items.AddRange() function and it requires an array pass (this typically shrinks the code down considerably) and if you want to mix and match arrays in segments it's easier. So here is the code; for doing so I am assuming that other developers use an "AddToArray" type function like me; if not you have to write the function or just replace the code with the actual adding to array.
''' <summary>
''' Convert an enummeration to an array.
''' </summary>
''' <param name="ConvertTo">Convert to return type.</param>
