Get A Regular Expression That Can Validate That A String Is An Alphanumeric Comma Delimited String?
Jun 23, 2011I need a regular expression that can validate that a string is an alphanumeric comma delimited string.
Examples:
123, 4A67, GGG, 767 would be valid.
12333, 78787&*, GH778 would be invalid
fghkjhfdg8797< would be invalid
This is what I have so far, but isn't quite right: ^(?=.*[a-zA-Z0-9][,]).*$
How To Trim Non-alphanumeric Characters From A String
Apr 20, 2008I'm working in Microsoft Access attempting to concatanate the results of a query into a single string. The code looks like this:rtn = Trim(rs.Fields(0).Value) Trim$(rs.Fields(1).Value)When I display the string in a list box, I only see the value for Fields(0) I cannot see the value for Fields(1).When I run the code in debug mode, I can see the value of rtn and it contains these non-alphanumeric boxes like this:"Earth4[] Admin[]" (where [] indicates the non-alphanumeric character)What can I do to cleanup the string, remove the [] and then display in my list box?

View 12 RepliesGame Programming :: Alphanumeric String Arrays
Jul 30, 2009I have a string array of size 51 CardListIn() representing randomly ordered cards in a deck {1d, 2d, ...14c} e.g. 9d = 9 of diamonds and so on. I then have 52 text boxes for user input. These have been put into an array of text boxes as so:[code...]
I want to search my original string array for any cards the user may input in any of the textboxes and then delete those entries from the string array.So say the user enters "1d" in one of the textboxes, I then want that removed from the string array.
I'm parsing through both the array and the text boxes fine, but for some reason that I cannot fathom, it doesn't find a match. The string array definitely contains "1d" and the textbox definitely contains "1d", but it doesn't register as a match. I've tried using Val() for the string array and the text boxes, but then it removes every entry beginning with a 1, e.g. "1d", "1h", "1c" & "1s".
Split String On Non-alphanumeric, Non-hyphen Characters
May 24, 2012Basically, for each character in a charArray created from the string to split, if the character is a letter, digit, or hyphen, I append it to a temporary string. When I see a split character or the last character, and the temporary string has value, I add it to the collection to return.
For i As Integer = 0 To (charArrayLength - 1)
charToInspect = CChar(charArray.GetValue(i))
If IsLetterOrDigit(charToInspect) Or charToInspect = hyphen Then

Code An 'increase' Button To Prompt A User To Input A Rate By Which To Increase Select Prices In An Array?
Feb 16, 2009I'm trying to code an 'increase' button to prompt a user to input a rate by which to increase select prices in an array.It should request the increased rate, then request a number from one to five, representing which price in the array to increase.Then, if 'increase' button is selected again and another number from one to five is chosen, then that element should be increased.It's working, but all the numbers in the array are changed. And, when I hit the increase button again, the array is repopulated below the first price increases instead of only replacing the designated price.
'declare 5 element array of prices
Dim prices() As Double = {12.2, 8.5, 12, 50, 2.4}

Dec 27, 2010Still working on that overlay. I am stumped on what I think is my last function. I have a + and a - button that needs to control a text box that has numbers in it.

VS 2010 Randomize Alphanumeric "text" From Button 1 To Textbox 1
Jun 2, 2012I am currently working on a personal project. I have the template for my program layed out and now just need help with some codes to go in it. I've looked for codes online to give me a better understanding but have had no luck so far. What I would like to do is to be able to "randomize" a line of characters with only capital letters and numbers 0-9. I need the overall length to be 14, but realistically 17. The displayed characters would be in this form. XXXX-XXXXXX-XXXX, so the dashes would have to fall into that area with all other characters being random. I want it to link from the 1 buton to the 1 textbox.
