View 1 RepliesWrite A Program That Validates An Inputted Ten Digit ISBN Number Using The Check-digit?
Sep 16, 2011I'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.

View 12 RepliesMultiply A User Set Digit By A Text Box Number?
Mar 14, 2009Ok, 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?

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

View 6 RepliesCan't Get Number From List Box To Display In Reverse In Text Box
Mar 10, 2012Build a small application that fills a collection (list) with 10 sequential numbers, and then prints the collection(list) in reverse order, skipping every other member, until the entire collection has been displayed. For example, if the collection contained the numbers 1 through 10, they would print as:
10, 8, 6, 4, 2, 9, 7, 5, 3, 1 The print out should be in that order no matter what sequential numbers are in the collection (list). If it were 21 through 30, output would be 30,28,26,24,22,29,27,25,23,21 and so forth.
Note: you must use a collection - do not write down the numbers directly to produce the output. Loops should be employed but the loop control variable should be used as an index or subscript number. Your code should work even if I change the list of sequential numbers to something else. Remember that indexes count from 0 first -- the first item in a collection has index 0, the second item in a collection has index 1, and so forth.
I've got the first part of the problem, getting the numbers in the list box, done with no problem. It's the second part I am struggling with. I cannot get the numbers (I am using 1-10) from the list box to display in reverse order in an adjacent text box.[code]...
