For example 0-619-15934-0 becomes 0619159340. I'm sorry if this is an easy question but I'm a noob when it comes to visual basic.
Here's my failed code.

Dim check, i As String
i = txtISBN.Text
If txtISBN.text = - Then

Hi, I am doing the SSN program.So when I type "345-584-5869", it should display "3455845869".I'm just learning how to use string manipulation.My problem is I cannot get all dashes remove when I output
' Name: Social Security Project
' Purpose: Removes the dashes from a social security number
' Programmer: <your name> on <current date>
[code].....
I have searched on google and asked friends, but have not figured out a way to add dashes while a user is typing either a phone number or a social security number or something of the like. I am using Visual Studio 2008, VB Windows Form. This is not for homework but I enjoy adding things to certain projects and thought this would be neat to incorporate into one of mine. I am also curious about allowing the user to enter the first three numbers for their area code and then send the focus to the next text box so that the user can type the rest of their number. I was thinking I could do something with the text box text entered event procedure where I would send the focus after three characters entered. Not 100% on the entire idea or if there is an easier way.
View 1 RepliesI'm trying to use regular expressions to take this number and only filter out any dashes, and just see a number:1-742-852-5412..I've tried ^d{7,}$, however, it doesn't recognize the numbers becuase it's including the dashes. how put together a regular expressions this disgregards the dashes?
View 7 RepliesI trying to display in a label the appropriate number of dashes based on the number of letters in a word that the first player entered.
Basically, when you click play, the first person enters a word, then the second player guesses what it is. That person has 2x #ofletters of incorrect tries. I just need to figure out how to get the dashes to display based on # of letters and not a preset one of 5 dashes. The original program accepts only 5-letter word so that line of code is Me.lblWord.Text = "-----". I have modified it so the user can enter any # of chars. I tried making the above line with a lot of dashes so it but the leftover dashes will stay there and the game won't end. Here is what i have right now for my play button:

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.

I'm trying to calculate the ISBN check digit of a number. First I have to remove all dashes from the ISBN; the rult is a 10-digit interger. For example 0-619-15934-0 becomes 0619159340. Then apply a weight factor to each of the first nine digits and sum the weighted numbers. AThe weight factor is the digit's position in the ISBN. THat is, the first digit is multiplied by 1, the second by 2, etc. Finnally I have to compute the check digit as the mod 11 modulus of this number for example. 209 mod 11 = 0 (i.e., 209/11 = 19, remainder 0_ This is the check digit. If the remainder is 10 ten the check digit is 0. Once the check digit has been calculated, it can be compared to the check digit given with an ISBN to determine if the ISBN is correct, or appended to a new ISBN as its check digit.[code]THe first problem arises when it tells me to make sure I enter all numbers when I should be deleting the dashes and then making sure that the contents are numeric. But even without it and without entering dashes the program still blows up.
View 8 RepliesI can get it to tell me if the ISBN I entered is valid or not, but there is a second part I need that I keep drawing blanks on. I need to be able to enter an ISBN with a missing digit marked by a "?" in the textbox i am entering the ISBN in. For those who don't know what an ISBN is it...
An ISBN (International Standard Book Number) is a ten digit code which uniquely identifies a book. The first nine digits represent the book and the last digit is used to make sure the ISBN is correct. To verify an ISBN you calculate 10 times the first digit, plus 9 times the second digit, plus 8 times the third ... all the way until you add 1 times the last digit. If the final number leaves no remainder when divided by 11 the code is a valid ISBN.
1.Write a program that reads a ten digit number and validates it.(DONE)
2.Write a program that reads in a valid ISBN with a single missing digit, marked with a ?, and outputs the correct value for the missing digit.(Ehhh....)[code]So i need help making it so i can input a ISBN with a missing digit marked by "?" and output a valid ISBN with missing digit.
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).

The following data is in the xls file: Name, Address, City, State, Zip, Phone. The phone number can come in in various values (with dashes and without). I have no way of controlling this data because it is an export out of some third party application. My problem is that the numbers with the dashes are being ignored by the Excel import. I am using the OPENROWSET to import.

View 1 RepliesI am using word 2010 VBA to clean up a "dot matrix" looking report. One thing I want to do is replace a row of dashes with a solid line. I think the code would look something like this:

select string
delecte selection
move up
insert solid line
