I need to define a regular expression that accepts Alphanumeric and the following special characters:
@#$%&*()-_+][';:?.,!
I've come up with:
string pattern = @"[a-zA-Z0-9@#$%&*+-_(),+':;?.,![]s\/]+$";
But this doesn't seem to be working.

generate the keys
Public Function GenerateCode() As Object
Dim IntRnd As Object
Dim IntStep As Object[code]....
the damn thing keeps returning 1 instead of 0. I do know i can simply change to 1 and be off the issue. but if is that easy to generate 1 the isnt easy just to break it. oh yeah the whole thing hangs when i generate the code? if i loop it, its able to get a 0 but i cant take the key thats in the loop?

I'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?

I 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".

I have to process a string that could include all sorts of non-standard characters and I've been asked to provide a regular expression that will match and remove all characters that are non-alphanumeric except punctuation and spaces. Is there a way to do this?

Basically, 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

I'm trying to use a GUID to generate 6 random alphanumeric characters (just letters and number). Is there a way to change the format of a GUID before it is generated. Or must I generate the GUID in its standard format and then manipulate it.

I have to match string like "DAY1","DAY2","DAY3"....."DAY31" with regex in vb.net. I tried something like this - ^?DAY(0[1-9]|[12][0-9]|3[01])$ but it did not work.
The pattern should have succesfull match if the source string is either DAY1 or DAY2 or DAY3 to DAY31 like so.

I'm looking for a decimal to alphanumeric number base converter library in Visual Basic that does not use recursion. [url]...
which includes a demo app but discovered that it uses recursion. The problem with it using recursion became apparent when I attempted to integrate the library into my own Visual Studio Express 2010 Visual Basic project: I got a stack overflow exception.
Now I could consider increasing the size memory allocated for the stack but it might be hard to determine what this would be, given that the recursion depth might vary depending on the value to be converted.

I 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][,]).*$

I 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.
