For my enterprise computing course we were asked to re-due a previous project which was a mortgage calculator that calculates your monthly payment except now using function and sub procedures.

I am here again begging for help with homework. I have to write this program to display three mortgage payments simultaneously using an array for three types of loans, that part of my program does work... Then I must amortize all three loans at once using a loop for comparison so the user can see: [code] I can't get the amortization to show. [code]
View 7 RepliesI am having a problem trying to pause/hesitate my loop for a couple of seconds and then iterate through the loop, but pauses every 10th iteration. I have my loan amortization displaying correctly but cannot get it to pause to list only 10 items at a time. 'This section uses the for loop to display the Loan Balance and Interest Paid over the Term of the Loan.
Dim counterStart As Integer
For counterStart = 1 To LoanTerm

I'm taking an introductory programming course, and am completely flummoxed as to what I'm doing wrong with my program. The problem seems to be in my arithmetic, as the program runs fine; it just doesn't produce the correct result when compared to the professor's control model.
I need to create a mortgage calculator, using the following formula: monthly payment = interest rate * loan amount * ( (1+ interest rate) ^ months) / ((1+interest rate)^months)-1) )
We have to use that formula, no other one. If anyone can spot an error in my code, please let me know what I've done wrong!
The code I've written is as follows:
CODE:
Write the program in VB.Net (not Web based) with a graphical user interface. Allow the user to select which way they want to calculate the mortgage: By input of the amount of the mortgage, the term of the mortgage and the interest rate of the mortgage

I have a multiple form project that is a mortgage calculator and I am having trouble with my Payment Numbers. One of the things I am listing in the amortization table is Payment #. The variable for that is Lyears. It seems like Lyears is set to 0 so it continues and never stops.

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 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:

Ok. I just took my final for VB and the last chapter we did was on procedures and functions. Functions was the only thing out of this whole semester that I was just completely lost. I'm trying to work on this cause I'm taking Advanced VB next so I wanna know what I'm doing. So I'm trying another tutorial in the book and I'm really lost. Here is what the it wants you to do.
Retail Price Calculator
Write an application that accepts from the user the wholesale cost of an item and its markup percentage. (For example, if an item's wholesale cost is $5 and its retail price is $10, then the markup is 100%)
The program should contain a function named CalculateRetail that receives the wholesale cost and markup percentage as arguments, and returns the retail price of the item.
When the user clicks the Get Retail button, the program should do the following:Verify that the values entered by the user for the wholesale cost and the markup percent are numeric and not negative. Call the CalculateRetail function Display the retail cost as returned from the function.
Here's what the calculator looks like and my code so far.

I have to calculate the maximum mortgage possible for a customer. If it is a single application, the customer can borrow up to three times their salary plus any savings and investments they may have.
If it is a joint application, the customer can borrow 3 times larger salary and 2 times the smallest, also borrowing against any savings and investments. In either case, the applicant is not allowed to borrow in excess of 90% of the purchase value of the property (including stamp duty and legal fees).
I have declared everything and done out the code, yet every time I calculate the max amount they can borrow, it comes up as 0. My code is below if anyone can spot problems.Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) _

I am creating a mortgage calculator using Visual Basic Express version. I am currently using the Console method, or command window view. I have it set up so the user can input the mortgage/loan amount, interest rate, term (in years), and have the formula for calculating the monthly payments.The problem I am having is that I need the program to display "all" the payments for the term of the loan, the loan balance/interest paid, and depreciating after each payment. The program should display a certain amount of payments, hesitate, then continue to display until it shows the end of the term of the loan. Basically, it is now an amortization loop formula I am trying to implement into the program.
View 3 RepliesI am suppose to be creating a mortgage amortization program that calculates the monthly payment and the amortization table for a mortgage based on user input of the mortgage amount, the interest rate and the length of the loan. I have worked on the program all week and finally got the program to compile; however, the interface does not give me any output. I already posted the assignment yesterday and am getting a C in the class but each week the program builds on the last week? Attached is the complet VB 2005 project file.

I am writing an application for my class, wherein I have a mortgage that will give the customer a discount of 1% on their interest if they pay early in the month, or penalize them by 1% if they are after the due date. Right now, I have it working with a checkbox that the user selects. However, I would like to have VB see the current date on the calendar I placed in the application already, and calculate the appropriate amount of interest based on that information. I am using Microsoft 2008 Visual Basic Express Edition on a PC.

I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.
I have already posted this assignment . The assignment is to create a VB.NET program that calculates the monthy mortgage payment for a $200,000 mortgage with an interest rate of 5.75% for 30 yrs. The program compiles and the interface window comes up but when you click the payment button nothing happens. fix this program because my other 4 assignments are based on this progam.

Number of downloads: 81This program is supposed to calculate the ever popular mortgage payment and amortize the loan in a list box. I keep throwing this error "Missing Member Exception" and can not find out how to fix it anywhere. Because of the error I can't even see if I can even get a calculation in the text box, let alone if the amortization will run. The purple text is where the exception is.

While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
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.
For example the function: Membership.FindUsersByName()
I'm redoing a program for my company and my boss wanted me to created the entire thing through functions...
For the task I wanted to know is it possible to have functions within functions?
Sort of like in C where we would have nested structures?
Its a FILE I/O, with robot commands, moves and verifications....
So I would find the line in an excel spreadsheet where it moves, the coordinate, put it into an array.
Take the actual results store them into a two dimensional array...etc, etc....
Another function would eventually compare the results with the moves, and within a tolerance.
I'm trying to learn how to use procedures?
Public Function mgboc(ByVal mboc1 As String, ByVal mboc2 As String) As String
Return mboc1, mboc2
End Function
But it doesnt work. I want it to "return" the parameters, but it won't even compile.
Why we use CLR procedures. Is there any significance of CLR Procedures or any example where CLR Procedure is the only solution?
