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.

''' <param name="ConvertTo">Convert to return type.</param>
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.
I have a list of rather meaningless codes that I'm processing with a VB.NET Windows application. For the business logic I'm writing to process those codes, I'd like to use meaningful constants (like ServiceNotCovered or MemberNotEligible) instead of the original codes (like "SNCV" and "MNEL").As far as I can tell, Enums can only map to numeric values, not to strings. So the best I've been able to come up with is a static class that exposes the constants as static readonly string fields that are internally set equal to the code values, as follows.
Public Class MyClass private _reasonCode as String() Public Property ReasonCode() As String
In my project, it is desirable to access built-in color, dash styles, hatch styles by a numerical index rather than their names. For example, I would like to access the colors in a loop from 0 to 140 and display each of these in side by side rectangles in a picture box. Then later, when I click on the rectangle for a desired color, calculate the index of the color from the position of the rectangle in the picture box and use this index to set another object to the clicked color. I understand the coding for all of this except for how to get the colors from the enumeration in the loop and later, after I get the index from the clicked picture box, how to I access the desired color from the enumeration by using the index obtained from clicking the picture box.
I want to be able to have the user type in a function, say ,x^2 + 1, and have the computer store this such that it can be recalled and plug in a given value for x. For example, say they type in x+4, the program will then (in a bunch of different text boxes) return the value of x+4 when x = 1, x = 2, and so on up to x = 10. But how can I get it so that it will store x+4, be able to recall it and replace x with it's given value
So I'm trying to import a function from a library I'm developing. I have "libraryD.dll" built for debugging and "library.dll" for release. Unfortunately, that means that I have to do this:

Now this would be fine but for ALL 40 functions this would make things very ugly to look at (and a tad bit unfriendly).I would like to do something more like this:
I do need to write a procedure that carries an array as a parameter- The array can be an array of many types (Dates, Double, Strings etc)- The number of elements in the array is unknownExample:Private Sub MyArrayRoutine(MyFirstPatameter as string, MyArray as array of Object()
Planning on migrating from 1.1 to 2.0 framework.After doing the automatic vs 2005 migration, it did highlighted lot of lines: due to unused variables and functions with no return type..Is there a tool which can fix those unused variables plus function with no return types.
I am creating a gridview and need to gather the data from various functions that return a type of IEnumerable. I've created gridviews using a dataset as a datasource, but how does one use multiple data sources(of IEnumerable) to populate one gridview? Like how do you combine all that into one dataset?
I am currently using double data types. The problem I am encountering is that sometimes the user will have to input a value of 0 in the required text box and this creates an error. My question is what data type will allow the user to input 0 and allow the mathematical functions to work properly. Decimals maybe?
I am using a background worker and am attempting to use the following code. However I keep getting this error on i "Unable to cast object of type 'ObjectCollection' to type 'System.Array'."

I was working on some code in VB.NET 2008 and somehow got a bunch of new functions to pop up in intellisense on a datarow array. I saw find, findfirst, sort, average, and lots more. They had an icon next to them in intellisense when I saw them. Then I went and changed some of the code and now I can't get them to come back. I have used 2005 and 2003 for a long time, but still pretty new to 2008.
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'm having trouble assigning values to an array and am getting the error, "Value of type MemberFocal.Member cannot be converted to System.Array" - MemberFocal.Member is part of a custom class and I am attempting to create an array of these objects. Here is the code:
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code. For example the function: Membership.FindUsersByName()
I have an address in the type 'array of bytes' (example): 81 ?? ?? 02 53 02 d0 27 To mess with it in visual basic, I use the format in Hex: &H81 &H02 &H53 .....
I do not know what 'put' in relation to the 'question marks' I've tried: &H?? &H_ &H00
I am trying to use a suggestion from Bob Powell to resize tiff files.I am getting hung up . The example I am following is at: http:[url].....I am getting hung up at "Dim g As Graphics.FromImage(bm2)" where it is telling me "Array bounds cannot appear in type specifiers.

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?
wrote 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.
I want to write an extension method that works with all kinds of arrays (Integer, String, Decimal, ...). It returns an array of the same type and size as the input parameter array.[code]...
I'm trying to create a function to parse out all values in a multidimensional Array with all but one dimension given. 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:
Function GetRow(ByVal arr As Array) As Array Dim result As (...) 'This should be Integer() if arr contains Integers, etc. Return result
