I am trying to make a loop to calculate the total costs for 12 days of costs. It has to compound sort of though. I need the total = cost for day 1(includes day 1) + cost for day 2(includes day 1 and 2) + cost for day 3(includes day 1, 2, and 3).....up to day 12. I have a for/next loop in my array, but it calculates the total for 12 days, but I need it to add as explained above. I have been strategizing and the program needs V= day 1 then add V to T. Then V needs to clear and then loop again so V=day 1 + day 2 then add V to T. Then V needs to clear and loop again so V=day 1 + day 2 + day 3 then add V to T and clear V.........up until all days are added together. If anyone has any suggestions or any idea of what I am talking about please comment! Here is the link to another forum that might explain the program in more detail:
I know how to read input numbers, but when I input equation like A+B, I can't use the equation to add two numbers. I tried many times but failed to use the equation.
I addressed a meeting and used the following....she worked there for 17 years.I was corrected later that it should have been 16 years.I argued that the first year of this persons employment was 1966 and her last years work was 1982. Therefore 17 years.Does someone have an articulate mathmatic reasoning that explains dealing with inclusive numbers.
I cannot seem to make my for next loop work for a class project. Essentially, I have a list box that is populated with strings of numbers. I am required to use a loop to sum the total of the numbers in the list box and display them in a label. I chose to use a For Next loop. However, it's not working. I'm getting an error when I try to convert the strings to decimals.[code]
I want to place two radio buttons in so I can select one of them to use one formula, and then select the other to use another formula. I want to use the I=P(1+r)^n formula and I=P(1-r)^n formula with the radio button text showing Appreciation and Depreciation.
Heres my copy of the original code.

I have a text file (*.txt) with a name in each line, like this:
Joe Dane Lisa Kelly
Now I want each name added with a number from 1 to 99.
Like this:
Joe0 Joe1 Joe2
[code]....
I have folowing code:
For n As Integer = 0 To (numbernames) - 1 strContents = objReader.ReadLine() For i As Integer = 0 To 100 - 1
[code]....
With this code all happens ok and a new text file is created with the desired name-list with added numbers.The only problem is that the last name doesn't get a number added from 0 till 99 but for example 0 till 17.
I am trying to loop through a dataset and process n numbers of records at a time.For example lets say I have around 240 records in my dataset. I need to loop through the dataset and then create a new batch of 50 records. so for the dataset which has 240 records I want to create 6 batches. Out of these 6 batches, 5 would have 50 records and and last batch would have 40 records.
how to loop an SWF file using specific frame numbers. I don't want the SWF file to play thoroughly. I know that frame 1 in Flash is 0 in VB, frame 2 in Flash is 1 in VB, etc.
My loop that needs to count and accumulate the numbers from a list box does not work. When I debug it reads the first line of the Do While loop then jumps to the code where it would average the numbers. Here is my code:
'calculate average 'get first item in list box lstListBox.SelectedIndex = 0
I have attached the form in initial state. What you don't see in the initial state is 10 hidden labels. I want the loop(which I am calling as a function??) to compute the numbers and display in the labels. Example, if I input 1 for the first term, 3 for the second term and 4 for the total terms, the first 4 labels should become visible and have in them one solution each:
1 - 1 2 - 3 3 - 4 4 - 7
Am I way off with what I want to do? Cannot use arrays, must be a loop.This is the compute button:
Private Sub BtnComp_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles BtnComp.Click Try
i have wrote a loop to search for duplicate numbers within a column in a database which i have got fine but when i find a duplicate i would like to get the all of the row so if 33 was a duplicate i would like to get the following row.
33MarkWhitesideM12/07/1958Michaeluuu
I have tried to do this buy use something i saw on msnd's website:
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like '33%'")
However if i change the line to notice the i beside the like
Dim foundRow() As Data.DataRow = customerDS.Tables("Details").Select("HNCNO Like 'i%'")
but i get Index was outside the bounds of the array. Ok i know that means that there is nothing in my array. What i would like is to find the duplicate row associated i. you will probably understand me better when you see the code.
Private Sub checkRowsForDups() Dim customerDS As DataSet Dim dupArray As New ArrayList
I need some guidance on a little program I'm making (one that I thought would take a couple of hours from start to finish, it's been days now ...) that determines all of the proper divisors of any given number up to the maximum value of a UInt32.
I need to add a loop to allow repeated checking of ISBN numbers, which should check to determine when processing should be ended and should allow exiting the program without having to enter an ISBN before quitting. I also need to use a Select Case for the three ISBN possibilities (ISBN-10, ISBN-13, invalid ISBN length).
I've got Visual Studio 2010 and I am looking to clean up my code technique, since I've taught myself and now I'm taking classes.
I'm trying to use a For...Next Loop so that I can fill a text box with sequential numbers. For some reason, all I can get in the text box is the last number and I feel that at this point I'm probably overthinking it...
All I want is on the button push the text box shows:
Here's what I have:

Once I grasp this simple concept, I can move on to the actual challenge ahead of me, but I really want to know the proper way to handle this with out going all spaghetti code.
I wanted to read input equation by user A+B and assign input user value to A and B to ask them to add and give answer. But I just can't get the code to work. I using VS2005 and VB.Net.[code]
Program Description: Fortuitous Dice is a game that requires two dice be rolled, one at a time. If p and q are the numbers rolled on the first and second die, respectively the value of the roll in the game is determined as follows:
P Q Rule (value of the roll and condition) Even Odd 2P + Q Odd Even P + 2Q Even Even P + Q When P not = Q P When P = Q odd Odd P + Q When P not = Q 3Q When P = Q
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
I have a decent understanding of the logic, the content. I'm working on a puzzle and I'd like to write a short program. I'm looking to fill in the following variables: AB.CDE FG.HIJ (they're part of coordinates, and the puzzle is part of a geocache) The puzzle asks you to determine which numbers correspond to certain colors, like this:
[code...]
I need to define A-J as >= 0 and <=9. I also need to say that each color is >= 0 and <=9, but that no color can be equal to another color (purple ≠yellow, orange, etc). some number combinations won't work. Purple and yellow can't be 2 and 5 respectively, because that'd produce a negative number. I'm guessing that there will be more than one possible result. So how do I create an equation that calculates this.
I would like to read a user's input equation or expression as a string (such as "y=5*(x+6)" or "cos(3)^2") and have the program evaluate it mathematically. Does .Net have any classes that could do this? Obviously, the compiler can already take a programmer's coded equation and evaluate it. Of course this is a different matter, but is there not a way to harness that same power with runtime user-created equations? Serialization or anything?
The other option (I guess) would be to create my own equation-generator - breaking an equation down into a binary tree of the numerical values and the operations I suppose. Aside from being a nontrivial task, my program needs optimal performance as these equations are in large loops. At the very least, this would add several conditional evaluations to each equation run - dunno if that adds up.
The project is "kWh counter", that is, a simple program that calculates the power usage.The incoming numbers are the Power of the appliance (lightbulb) and the voltage (230/120).The formula is W=P*t that is multiplication of the power and the time it is used.I thought to connect it with a timer and the passing secconds multyply with the power, and, write the ussage on a label.This would be something like a simple digital power counter.Note that the voltage is not necesary.I am from europe where the standards are 230V.
My assignment is to get the Get Monthly Income (Num1)Get Monthly Home Rent/Mortgage (Num2) Get Other Monthly Payments (alimony, child support, student loans) (Num3) Display Allowable Monthly Car Payment Display Maximum Car Value (interest rate based on credit) (answer) Public Class Form1
What I need to do is automatically generate a specific PIN number based on the current date. The formula goes like this: MMDD + 1234 = PIN. (ex. Date = 3/26/2012 -> 0326 + 1234 = 1560; With 1560 being the PIN number. I then need the PIN number to display as text, but that's the easy part, I really just need assistance with getting the date information in the proper format for the equation.
after a lot of research on formatting Maths equations, apparently using MS equation edior is the easiest way to do it. But, I have no idea how to use it in VS 2008.
