View 2 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 1 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:
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

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.

In our VB6 applications, we added a few utility functions for tracking the amount of time spent in a function. We did this to track performance bottlenecks. Basically, how it worked was there were two utility functions:
StartTickCount() and EndTickCount().
You would pass the name of the function in each, and the functions would use a dictionary to get the tick count when StartTickCount() was called, and then subtract the tick count when EndTickCount() was called. This wasn't perfect because it didn't of course take into consideration that calls to get tick count takes time, etc, but basically it worked for our purposes. How to make sure to call StartTickCount() at the beginning of each function and EndTickCount() at each exit point:
Private Function SomeFuction() as String
' indicate the function started
StartTickCount("MyClass.SomeFunction")
' some logic that causes the function to end
[Code] .....
Anyway, is there any functionality built in, either through the VS 2010 debugger or in the System.Reflection namespace, to do something similar in VB.NET? Basically, what I want is to log the number of times each function is called, the total amount to time spent in that function, the average number of seconds spent in that function, and the maximum amount of time spent in a single call in that function.

I know that it's possible to Call a stored procedure from a Windows Application made in VS 2008. But, is it also possible to Create one? If so, isn't it possible for someone to create a SP that will delete all the data in a DB,when executed? Is there a real danger that someone could use an application that communicates with a DB to create such a procedure?

Suppose i want to draw semi-random ellipses on my form.Is there any way i can check if they get clicked at a later stage?Is there any way of storing the location of individual ellipses and then comparing the mouse-click to my list of locations to see if one was clicked?
I can imagine how it could be done with squares or rectangles, but i dont know how to approach it with ellipses.
Im sure this has been asked before, but i've spent a good while searching around for something i can use and came up emptyhanded.
I want to make a program that will track Do Not Rent (DNR) People.I'm a intremediate vb6 programmer and have not coded in a long time.I do have and wanting to do this on VS2008 professional in VB2008.I did a simular program from a vb6 book about 12 years ago. it was a address book that i changed a little to add some things I needed it to keep track of, and it saved everything in a text file.I want to know what the pros and cons are for using a text file? xml file? or a data base?the data i be keeping track of will be vital statistics as name, state id number, id type, ect. and a picture of the id from a scanner or import from a .png, .jpg, or tiff image.If i use a data base file either Access 2007, MySQL, or SQL 2005/2008 file, do i need to have Office, MySQL, SQL 2005/2008 programs installed on the the computer im doing the programming on? do i need to have the above programs installed on the target computer?i do not think a txt file will work for me because of the picture i want to keep with the data not seperatly. So to make it a little more clear I want to be able to add, append/update, not to be able to delete a record, and be able to search the file for a record.I want to be able to navigate the records or file with first, previous, next, and last. each record will be showed seperatly.I would like to have a STATUS (lol thingy) that only my wife or I can change but let my employees be able to enter the rest of the information on there own. the STATUS Levels will be like 1st warning, 2nd warning, 3rd warning, DNR, and Rentable at our discression. I want it to only allow changes to status if they have the proper password. so i do not know if this also elimates txt files or xml files as an option.and when the wife, my employees or I make an entry I wanted it to add the time and date with the comments we entered in with the initials of the person whom entered the data. so i was thinking i will need to have security levels in my program and give each person a password so the program can fill out most small data itself.
if i do decide to use a database file to store the data, picture, and employee information can it be done with 1 table, or should i try to seperate the data in seperate tables? should i use one to one or one to many? I do not think one to many would be the best solution? it been like 12 years since I did any database programming in school and it was dBase3. If u think it be best to use multiple tables could u give me an example as to how to seperate the data.The client info would be like a address book with a picture and a comment box that will automatically add a date/timestamp and the users initials with a space between every updated or appended entry., and the employees would have there login in name and password, and initials.I was thinking of making a wizard to enter the data in for both employees and the DNR's as for people changing the date on the computer and entering info so to make it look they entered data on an earlier date I was thinking of having it log onto the internet time server and setting the date/time of the computer in the background as it loads up.
I would like my application to respond to when the user press the media keys on his keyboard. Anyone know how to make my application capture this when it's in the background.

I have to write a program that will allow a usert o track the invitation list for a party. The user can enter the name of a person to be invited. When the send Invitatin button is clicked, the name appears in the checked listbox. This counts as an invited person.When an invited person confirms that they will be attending, the user will check the name in the checked listbox. this counts as a confirmed person.
What I am having a hard time figuring out is the codes! What would I declare my integer variables to hold the count of invited persons and the count of confirmed persons? And how would I code a loop to check if the name enetered in the name textbox already appears in the list box, if so, display a message telling the user that this person has already been invited?

I used to develop applications in VBA, but now I'm using SQL Server 2008 Integration Services for a lot of the functionality, and using VB.NET as the scripting language where needed - all of which are new to me. I need to do the same string manipulation in several different SSIS tasks. With VBA, I'd simply write a function and declare it Public, and I could use it from any module. E.g.
Public Function MakeId(ByVal Country As String, ByVal Postcode As String) As String
....
End Function
' later...
Dim MyId as String
MyId = MakeId(County, Postcode)
But when I do that in a Script Task or Script Component, I find I can't call the function from VB in any other Script Task or Component; it says MakeId is undeclared. It works within its own 'box', but not from anywhere else.

I'm taking a class in VB, so I have numerous projects. I have a lot of useful functions and code, and I'd like for them to all be included in on piece of code that all my projects can use. The problem with DLLs is that when I build, the EXE needs the DLL to be in the same folder. I want a standalone EXE file. Is there any way I can have a DLL in a different folder than the EXE and still use it? Or is there some better solution to having useful code somewhere so when I update that code, it will affect all of my projects?

i have an application that's in development, but some modules of the application are already built, so the application it's installed in several computers. In my code, i call an external class that i built with several functions that i use in multiple applications, in this class i have a small piece of code that checks in the network (internal), if a new version of the application (Msi File), of the current application it's available, and if it's available, it runs the Msi file.
msiexec /package MSIPackage.msi That worked fine in windows XP, but now some machines have been upgraded to windows 7, and the user need other credentials to run the package. (Elevate Privileges). Other problem it's that in my application i create several folders in the installation and the user doesn't get any permissions to write in the folders.For example i have one Log folder, and i can't write any logs to it.

etc...
Are there any subtle differences that should be noted?
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.
