Small Installment Calculator
Mar 29, 2010
I have a small installment calculator assignment, I have only used VB6 before but i am required to use .NET (using Visual Basic 2008 Express).
There are four fields:
1. Loan Amount (10,000.00 - 250,000.00)
2. Loan Term (5 -25 years)
3. Loan Interest Rate ( Input to 2 decimial places)
4. Payment Frequency (12, 4, 2, 1)
I need to calculate an Effective Rate as:[code...]
Then calculate an Installment Amount:[code..]
And finally display installment amount on the form.This is the code I have so far, but I am getting a NaN result for the InstAmt[code..]

I've been browsing these forums the past couple days, and I've got most of my program figured out now, but I'm seeking advice as to where I should do a few calculations, and how I should pass my data between my input and my output forms. my basic program consists of a user entering 4 positive values on my main form - and then I calculate various constant percentages based upon these numbers. I then need to output these values into various labels on my output form. I have successfully implemented doing all of this on a single form, but I have over 30 outputs to display so it was a bit cluttered on a single form.
1) is it better to do all my calculations within the code of my input form and output the calculation results to the output form, or is it better to take my inputs, send those 4 values to the output form and do my calculations and output there? (i'm thinking it's the latter and is how i'm currently coding this)
2) in my second form, I cannot remember how to pass values between forms and I have not been able to find any examples that have jump started my brain into remembering. Currently I'm planning on sending my 4 inputs to the output form, doing the calculations, and outputting everything there.
for my input page:
Public Sub btnCalc_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalc.Click
'each textbox is programmed to only allow numerals
'Get input from user
[code]....
and i think this will have the form calculate everything when it loads up. I'll later add code so that after I close it - I'll have my input form reset so i can immediately run another set of calculations. (currently not programed, i need to get the basics up first)

I'm having trouble getting started with this application I need to do. Here are the details:
Its an application to calculate student grades for a group project. Create a text file to store names of 5 students, line by line. In a separate file enter peer evaluations from 0 to 1.0. Enter these numbers for evaluations:
1.0, 0.8, 0.9, 1.0, 0.6
0.2, 0.9, 0.5, 0.6, 0.7
0.5, 1.0, 1.0, 1.5, 0.9
0.9, 0.9, 0.9, 1.0, 1.0
1.0, 0.9, 1.0, 0.8, 0.9
This means that student 1 gave 1.0 evaluation for himself , 0.8 for student 2, 0.9 for student 3 etc.Student 2 gave 0.2 for student 1, 0.9 for him- herself, 0.5 for student 3 etc. Read these into a 2-dimensional array. If any of the values is greater than 1.0, set them to 1.0. The program should calculate the average evaluation for a student. While doing so, the program should ignore evaluations that student gave to him-herself. Populate a list box with student names when the form loads. The user should enter a project grade (same for everyone) in a textbox. Then the user can select a student from a list and click �Calculate� button. The program should display the project grade for that student by multiplying average evaluation by the grade for the whole group (project grade).

I have my software installed on numerous machines and on all but one it is fine, however on this final computer the font comes up very small. It is only in my software, nothing else on the computer. I'm using Arial size 10 and bold, nothing fancy and as i say it works on all the others.

I recently asked a question about translating a code sample I found on on the internet from C# into VB and I was given links to websites that automate code translation [URL].. I am very new to VB and unfortunately the VB that the translators returned doesn't compile in Visual Studio 2010. I am hoping someone can help me fix the non-working portion of VB code.
Here is the C# code I am converting into VB:

When I try and run the program I get an error stating
"Value was either too large or too small for a Decimal."
On the line that says
principal = payment - InterestPaid
I've included the rest of the code as well. Perhaps this is a downside of staring at the screen for so long.
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim payment As Double
Dim result As String

I have writen a program in Visual Studio 2005 professional. Part of the program functions is to store customers details. Part of this details include a phone number. I can add a customer and include his/her telephone no. which is 12 digits long. But when retreiving this customer I get the following error.Value was either too large or too small for an Int32. Couldn't store <+23320805060> in Phone Column.Expected type is Int32.The program runs fine If the phone numer is less than or = 9 digits. The datatype i am using is for the phone column is varchar(50). I have tried to change the data type to bigint, int and nvarchar(50) but the problem seems to persist. I am using the SQL database but i seem to be hitting a brick wall on this matter.

I've made a simple calculator, everything works except for the adding (+) function. Such as 3 + 4 = 34 (which it doesn't). It takes it as a string, rather than a number.
Here's what I have so far:

Again, the problem is the adding is not functioning.

Sorry in advance. I emailed myself my coding since I don't have vb on my personal computer. Sooo, the format is going to be off. But my program allows the computer to generate a random date. The user has to guess what day of the week the random date lands on. I have written the whole code. It all works except when user checks his/her answer. The answer always comes up as incorrect. Here is the coding:
