View 1 RepliesIm currently working on a car service program on Visual Basic. The user simply selects some radio buttons, enters a couple of values and at the end the lablels are SubTotal, VAT and Total. Can anyone tell me how I calculate the VAT, the VAT rate I need to use is 20%. I currently have an appropiate answer for the Sub Total. I know I need to multiply the SubTotal amount by 0.2 but how do I do this using Procedures and Functions?
View 5 RepliesI have to make a mastermind game in VB 2008 using procedures and functions and not using any public variables. There are 5 procedures and functions:
1)Sub ChooseColors (intPeg1Color, intPeg2Color, intPeg3Color) which generates unique numbers to represent the colours for the secret arrangement of the coloured pegs.
2)Sub GetGuess(intPeg1Guess, intPeg2Guess, intPeg3Guess, blnDuplicateGuesses) which gets the unique guesses of the three peg colours from the user.
3)Function CorrectPegs(intPeg1Guess, intPeg2Guess, intPeg3Guess, intPeg1Color, intPeg2Color, intPeg3Color) which calculates the number of correct pegs chosen by the user.
4)Function CorrectColors(intPeg1Guess, intPeg2Guess, intPeg3Guess, intPeg1Color, intPeg2Color, intPeg3Color) which calculates the number of correct colors chosen by the user.
5)Function HasDuplicates(intPeg1Color, intPeg2Color, intPeg3Color), called from ChooseColors(), which returns True if any of the peg colours is a duplicate with any other peg colour.
Here is my code so far:

Private Sub btnDone_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDone.Click
If MessageBox.Show("Are you sure you want to exit?", "Confirm exit", MessageBoxButtons.YesNo, MessageBoxIcon.Stop) = Windows.Forms.DialogResult.Yes Then

How I can get the variables from ChooseColors (peg1Color, peg2Color, peg3Color) and the variables from GetGuess (peg1Guess, peg2Guess, peg3Guess) and use them for the functions, CorrectPegs and CorrectColors.

View 3 RepliesI'm writing a VB.NET function with a ton of overloads. I've seen that most .NET functions have parameter descriptions in IntelliSense. For example, when typing in String.Compare(, IntelliSense says Compares two specified System.String objects and returns... you get the idea. This description changes and you click through different overloaded versions of the same functions. When you start typing in something for a parameter, it describes the parameter you're currently inputting as well. Example: strA: The first string to compare..

View 2 RepliesWell I am a new to VB.NET, converting a legacy system to .NET world. Recently I have been reviewing the already existing code since I joined the project quite late in the team. I find that there are many shared functions (not shared class) inside many classes. I doubt this may create some problem if two requests ( i.e two different HTTP request to the same method as it's a WCF application, of course exposed methods are not shared but internally called methods are shared) comes to the same shared method and both the calls to the method may have different method parameters/arguments, overwriting each other's arguments. In short, if shared method has a list of arguments which is going to be processed, is there any chance of inconsistencies in the light of multiple access to the shared method via two http requests.

View 1 RepliesI'm almost sure that I've seen this somewhere, but I can't find it anymore. Or maybe I'm imagining it, which would'nt be strange either.
When creating a sub or function and adding parameters used when calling it.
-Is it possible to list the parameters that I can enter when using it somewhere in my code?
E.g.
Public Sub MessageMain(ByVal Message As String, ByVal MessageType As String (List of possible values for MessageType)) Same for example as when you have boolean values in a sub/function. As soon as you use that somewhere in your code intellisense will present you with True/False to select.
I'd like the same for parameters in subs or functions I create and calling them from somewhere in my code. Saves me the trouble of remembering which options are available for those parameters.
How do I effectively declare a Global Array which I can access the values of that array from any procedure? I have a Userform from which I will call various sub procedures depending on the actions performed on the useform. I have one procedure (Procedure1) where I have set up a multidimensional array and input values to it. I have another procedure (Prodedure2) where I want to access the values in the array - I DO NOT want to pass the array values directly from Procedure1 to Procedure2.

View 3 RepliesI just got upgraded from VB6.0 to VB2010. I'm trying to move some of my program functions over and I'm getting an error on the ones where I use optional... Public Function GetFolder(ByRef FTT As String, Optional InitFile As String)
I get the error at the end of the line, after the close par...the error is "optional parameters must specify a default value".
What I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).
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>

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.
