Im 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?

I 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:
Mastermind
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
[Code] .....
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.

I can tell all the calculations are being made (my computer is loud), but it's just not outputting.What should I look out for when modifying stanav's code that would cause the output file not to be outputted ?

I have a solution with more than one project and the main project contains buttons to open forms from different projects that are in the same solution. Say Project1 is the main project and Project2 is the different project that gives the following error when i compile it:
Error 3 'Sub Main' is declared more than once in 'SystemInformation': SystemInformation.Program.Main(), SystemInformation.My.MyApplication.Main(Args() As String) System Information II
I have already seen other threads with this question but it does not work for me because i have more than one project.For Project2: Application Framework is disabled and the startup object is "SubMain".

Recently i bought the book by Troelsen about VB and the net and tried to run the programs e.g.:
Module Module1
Sub Main()
EntryPoint.Main()
[code]....
I had to add the first sub "Main" otherwise it would not run. Is it possible to do without that sub in the way member OLiver does in the examples he provides?

I was curious if anyone has heard of writing a program with functions only. It is part of my current assignment but all the examples I have seen all over have at least subs for the click events. SO I am a little confused to say the least.

Is it possible to use a sub Main() to start you're application rather than a form, if so how? Also how do you implement the cmd commands such as "[application path here]program.exe colourclicker" The above command would start the program but would only show a certain form.
EDIT Is there another way other than unchecking the 'Enable Application Framework' checkbox? (As this disables XP Styles and uses the ugly classic windows styles)

My software will simulate a few hundred hardware devices, each of which will send several thousand reports to a database server.Trying it without threading did not give very good results, so now it's time to thread.Since I am load testing the d/b server, some of those transactions will succeed and a few may fail. The GUI of the main program needs to reflect this. How should the threads communicate their results back to the main program? Update global variables? Send a message? Or something lese?
Now, if I update only at the end of each thread then the GUI is going to look rather boring (and I can't tell if the program hung). It might be nice to update the GUI periodically. But that might cause contention, with threads waiting for other threads to update (for instance, if I am writing to global variables, I need a mutex, which will block each thread which is waiting to write).
I'm new to threading. How is this normally done? Perhaps the main program could poll the threads, instead of the threads iforming the main program?

I have developed an application with a plugin architecture using interfaces. I realized that when I release the API for 3rd party plugin development, someone would be able to create a loader program to replace my main program quite easily. Is there any way I can make the plugin dependent on my main program? All my main program does is get an icon and a description of the plugin from the DLL plugin (using the interface) and then calls the dll's interface function to create and display the form.

I have been trying to build a game bot in vb.net.One of the main problems is getting access to the text the game prints on the screen so I have been trying to hook the games calls to the windows api drawtext and textout functions.I have been hunting for examples of how to set up a hook in vb.net for a long time without any luck.I have found it impossible to translate examples in old school vb, C++, and C#.For convenience's sake I would like to use the freely available deviare and/or easyhook libraries.

That is if the user seleects to find side a. When the messagebox pops up, it doesnt state the previous calculation, why is that?

I have an application I've written for some of the people at work and there is one bug that I have no idea how to solve. The application is multithreaded so that the main form can be updated with new information as it comes in. Throughout execution, several other forms come up as well (one at a time).Every so often I get reports that the program freezes. When I check out the program it looks like the main form is not being updated(checkboxes are see through, textboxes are blank) and the main form can't be moved around. This only seems to happen sometimes when the program is left for long periods of time (+30 min) and only on the released .exe and never in the debugger(as of yet). I've tried leaving the program running overnight and it had no problems.

I am new to using VB2010 (and coding in general). Also brand new to these forums . Okay so I am making a program that: allows the user enter the number of customers served for each of 12 months into an array. The application should calculate and display the following statistics: total number of customers for the year, the average monthly number of customers, and the months with the highest and lowest numbers of customers. Use inputBox to get user input. Do not accept non-numeric or negative numbers.
The problem that I am having is that I do not know how to display which was the best and worst month. I imagine I need something that targets the highest/lowest number and finds the text in the corresponding index but I'm not sure how to do this.
