Write A Program That Validates An Inputted Ten Digit ISBN Number Using The Check-digit?

Sep 16, 2011

I'm supposed to write a program that validates an inputted ten digit ISBN number using the check-digit at the end to ensure that the sum is a multiple of eleven. Before calculating this and detecting if the entered number is indeed a valid ISBN, we're required to check the first nine digits and see if they are indeed integers. After this the tenth digit is checked to see if it is "X" (for ten) or 0-9.

With the code I've written it keeps returning false for whether or not the ISBN is valid, even with valid numbers. I feel like its something to do with the hyphens; have I misused the replace function?I'm a little lost on how to make my code work, but I'm fairly certain my logic is okay so far.

ATM System - Check Card Number Matches Up To The Users PIN Number

Mar 13, 2009

I am trying to make a basic ATM system, iv got all the interface done and I have made the link to my SQL database etc. the part i'm stuck on is how I can run a check to see if a bank card number matches up to the users PIN number. To simulate the user putting a card into the machine I've used a combo box, and that lists all the cards, that haven't been flagged as confiscated (there's a column in my ATMCards table that I can set to true or false) then after the user has selected a relevant card there's another text box where they can enter in their PIN number.

Now what I want to do is, if they chose the card number 1234567890123456 in the combo box and they enter in the PIN 1234 into the text box, then, after clicking the check PIN Button if the pin is correct they need to be taken to another from where they can check their balance etc., and if its wrong they got three attempts after which point i want to flag that card as confiscated.

Random Number Lotto Match With User Number Picks?

Nov 4, 2008

I am trying to create a lotto simulation, but don't know how to continue.I am using numericupdowns to allow users to select 6 lotto numbers. and labels to display what they have chosen, but i'm not sure how to prevent duplicates without creating a large number of If statementsMy question is, is there an easier way to prevent duplicates without writing a bunch of if statements?here is my code:

Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Lotto1, Lotto2, Lotto3, Lotto4, Lotto5, Lotto6 As Single Lotto1 = Val(NumericUpDown1.Text) lblLotto1.Text = Lotto1 Lotto2 = Val(NumericUpDown2.Text) lblLotto2.Text = Lotto2 Lotto3 = Val(NumericUpDown3.Text)

[code]....

I don't understand how to save the user selected numbers, let the computer generate 6 random numbers, and match the two sets of numbers together to see how many matches there are. As far as I understand the numbers should be stored in 2 separate arrays and then matched together to find any matches.

VS 2005 Getting The Correct Number Of Attributes To Match The Correct Number Of Text Boxes?

Apr 18, 2009

I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code

Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)

[code]....

The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.

How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)

Multiply A User Set Digit By A Text Box Number?

Mar 14, 2009

Ok, now I have another problem that I cant seem to figure out I now have the "Labour charge section" just incase the service requires one. which in alot of cases it does. So, I have a test box called text box 1, which I want to be able to insert "hours worked" which is a "digit" and then Have a fixed value, of five. Which the user can later change. The number from the box, and the user specified Hourly charge, must then be multiplied to create the total labour charge which will be inserted into a label view. So, my question first, is, how would the user be able to set the hourly charge and then not be able to change it by accident. I was thinking of having a tool strip with an options tab and then setting, and then you use that to fill the info, and have that hourly charge, hidden of the actuall form so that it cant be changed by mistake. Then, on to of that, how would you multiply these two numbers?

Algorithm - Take A Database With Multiple Entries Of 11 Digit Number?

Jun 21, 2011

I am trying to take a database with multiple entries of 11 digit numbers and run a check sum algorithm that adds the 12th digit to the 11 digits as an output.The algorithm is as follows:

Add sum of odd digits starting with first digit, then multiply by 3.

Add sum of even digits, then add to result of odd digits multiplied by 3.

Take result and divide by 10. The remainder is the check sum which needs to be added to the end of the original 11 digits.

Credit Card Project Program?

Feb 25, 2009

I am working on a Credit Card Project Program. Where you can create an account by typing in an account number which then starts you out with a $1,000 credit limit and balance.I have most of all the programming done for the project. Except for the updating of the current balance when charges are made and I'm having a problem with the interest which works but only shows you the interest fee when you calculate and not the interest fee + balance due. But I wont worry about that now.

What is the method of doing this. Can I write a new function that will update the balance available based on the charges or payments made? Or can I somehow program that into the current functions?
