I have found a Regex that test if the text passed to a TextBox is an email.
If Regex.IsMatch(email.Text, "^(?("")("".+?""@)|(([0-9a-zA-Z]((.(?!.))|[-!#$%&'*+/=?^`{}|~w])*)(?<=[0-9a-zA-Z])@))" + "(?([)([(d{1,3}.){3}d{1,3}])|(([0-9a-zA-Z][-w]*[0-9a-zA-Z].)+[a-zA-Z]{2,6}))$") _

I am pretty new on regular expressions, but as far as I've been wandering around Google, the only thing I could do to solve my problem is through regex. I have a collection of strings which have patterns like these:
"3 - Orange, Lemon"
"4 - Pineapple, Orange"
"12 - Lime, Strawberry"
[Code]...
Only the first few numbers. A comment, suggestion, or point to the right links/articles would help because so far I couldn't manage to find a decent tutorials that easy to understand.
I am trying to parse the digits to store in a variable from a string in VB.NET (would like to also include the decimal point).
Here is an example string: Refund issued for $27.74
I'm creating a calculator, and I need a way to get the numbers surrounded a character I provide.
For example:
Equation: 5+5*2/7
Character: *
Result: array(5, 2)
I was wondering if regex would be able to do this and if it can.
I am trying to gather all numbers in this string which is the name of an image file. The name of the string is ABC09072009XYZ777000111.jpg. When I use
Dim rx as new Regex("d")
Console.Writeline(rx.match(input))
It only returns the first set of numbers before the xyz. I need them all.
I am trying to wirte a function for a Phone number class called "import phone number". It should take any string with 10 digits in it somewhere (and allow for an extension), and import them into it's own properties: AreaCode, Prefix, Suffix, and Extension (aaa-ppp-ssss-xxxx...).
I check the input with a regex to make sure it's valid, now i want to tokenize those pieces into their respective properties. What I have looks like this (incomplete):
Public Sub ImportPhoneNumber(ByVal anyNumber As String)
'phone number is 10-digits long, e.g.: 012-345-6789
Dim reg_exp_10 As New Regex("^((D*)d(D*)){9}((D*)d){1}(((x|ext){1}(d)+)?|D*)$", RegexOptions.IgnoreCase)
[Code].....
(^(+[1-9][0-9]*(([0-9]*)/-[0-9]*-))?[0]?[1-9][0-9-]*)/(^([0-9]( /-)?)?((?[0-9]{3})?/[0-9]{3})( /-)?([0-9]{3}( /-)?[0-9]{4}/[a-zA-Z0-9]{7}))$I'm trying to write a RegEx to check for International and Domestic phone numbers. This appears to be working for domestic phone numbers but it doesn't look to work for international numbers. Is there something I'm missing? Can anyone else try this with numbers you know and just let me know if it's missing anything?
View 1 RepliesI worked around to modifying regular expression below but i could't get what I need. I google it, many things found but not for what i want.

Here's the latest incarnation of the code I've been trying:
objInfo = System.Text.RegularExpressions.Regex.Split(
newLine,"(d{3,5})|([0-9]+[.]+[0-9]+)|(w*)")
I'm having trouble because I'm avoiding getting many blank spaces in the array after splitting. I'm trying to avoid using the optional | character but I get no results when I set it up without it!

I need the code to filter the data entered in a textbox. Although it accepts all the characters during runtime, the code should remove all the strings and alpha numeric characters except the numbers (which would be my output). I tried the following code but guess it won't do:

I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?

Probably a dumb question, but can you write a unit test project in one language to test against another project in a different language?I'd like to translate one of our VB assemblies into C#, but want to build unit tests to verify the results. I've tried to set a unit test project up to do this, but I can't seem to access the VB code within a unit test... I can't figure out if I'm just missing/doing something stupid, or it really isn't allowed.

So how would I use .next (random numbers) to randomly select something from a list of numbers but it can't repeat the number?I could do:
dim num as integer
dim r as new random
num = r.next(1,5)
if num = 1 then
elseif num = 2 then
etc.
That wouldn't work because it would repeat.If I donwload someone's game can I disect it in VS? :0 I tried going to open project, then I went to the folder and clicked open.

View 1 RepliesI am making a program, where the user enters 6 numbers in 6 different text boxes, and it displays the larger of those 6 numbers. But I also want to make it where if the user enters a string value (like S for instance) in the text boxes, it gives an message and says "please enter the numbers again" and the user gets to enter the 6 numbers again. But when I do try to do that, it gives an error message saying conversion from "w/e the user entered" to Double is not valid. If the user just enters the numbers, it works fine. However, I am trying to make it if the user does enter non numeric value, it gives a message window and the user can reenter the numbers again.
Here is my code Example
CODE:
This is where I am trying to use IsNumeric to show a message if a user does not enter a string so the user can renter the numbers again, but when the user does enter a string value (say in textbox 1) it gives me an error message saying conversion from "S" to 'double' is not valid.
CODE:
Then right here this is where I have my series of ifs statements, this part works fine, it displays the largest numbers of the 6 textboxes every time. Error free.
CODE:
And do this with variable number 2, 3, 4, 5.
I know there are easier ways to do these with arrays and stuff. But I am not there yet. I am still learning about ifs and stuff.
I have just about completed a .NET project to write a program to randomly select numbers for a Bingo caller. Over the last month or so Ive learned a lot about .NET but heres something that I consider to be odd and maybe one of you guys can offer an opinion.
One of the features of calling Bingo in a small local club is that callers often use little sayings to accompany certain numbers, I expect youve all heard of (say) All the sixes, clickety click for 66 or 5 and 9 the Brighton line for 59 etc. My little program gives an option to incorporate these with a prompt for the caller that can be edited outside of the program. One of these conventional sayings is used when a number is reversed 12 followed by 21 or 45 followed by 54 for example, when the caller might call (say) 1 and 2, one dozen, number 12 And the other way round 2 and 1, twenty one.
So, I programmed in a bit of code to detect this and to over-ride whatever might otherwise have been the quote with And the other way round and set about testing it. Ive been through literally dozens of full 90 calls watching for the occurrence of a reversed number, spent a few hours doing it, and not once has it occurred which is to say the least, unusual.
So, Im wondering about the Rand Function, could it be that it isnt possible for a reversed number to be selected? Just so you know, I randomly pre-select the order of all 90 numbers, I fill each of the 90 elements of an array with a random number first checking that the number selected hasnt already been stored, if it has, I just get the next random number (and check that too of course), but I cant see how that could prevent reversed numbers being selected, especially in light of the fact that frequently it's not the 'next' number that's used.
am writing an system application for a company that must generate inquiry id and order id automatically. Whenever a customer makes a new inquiry or new order by clicking the add button, an automatic number should be displayed in the text box and when it's saved, it should be saved in the database access.
