I need to validate user input in some fields, where these are defining how to show time in some views.
Requirements: Time format must be expressed in Microsoft .NET way (check this MSDN Library article if you want to learn more about framework's date and time formatting: [URL]. Keep in mind I'm looking to validate the format instead of an actual time string.
For example, user may input:
HH:mm
hh:mm
ss
hh:ss
mm:ss
... and so on.
In fact, it should validate from the shortest to longest time format available. Another point is I need to do it in client-side using JavaScript. In other words, any given regular expression by you should work in browsers JavaScript regular expressions' engine. I can't use ASP.NET validation engine, or any other. Because of project's requirements, I need to avoid that.
I'm trying to format a phone number in VB.NET 2008 in the code. user can type in this numberfor example: (203) 555-1212The format I would like the phone numbers to appearis this:203.555.1212I haven't been able to find the correct format.I tried this:Dim x As String = "(222) 333-4444"Dim joe As String = String.Format("{0:###.###.####}", x)

View 6 RepliesI am using VS 2005 pro and VB.NET. How do you format the DataGridView.DefaultCellStyle.format property for zip codes and phone numbers. I have a zip code and phone number column(s) that I want to be formatted. I have tried a lot of different things:
Zip code: "99999-0000" or "Phone Number: "(999)000-0000" or "(000)000-0000" and the like So far nothing has worked. I can get my date columns formatted correctly, but not these. Can any one give me some examples that work?

View 3 RepliesIn the application I am currently working on, I have an option to create automatic backups of a certain file on the hard disk. What I would like to do is offer the user the possibility to configure the name of the file and its extension.
For example, the backup filename could be something like : "backup_month_year_username.bak". I had the idea to save the format in the form of a regular expression. For the example above, the regexp would look like :
"^backup_(?<Month>d{2})_(?<Year>d{2})_(?<Username>w).(?<extension>bak)$"
I thought about using regex because I will also have to browse through the directory of backuped files to delete those older than a certain date. The main trouble I have now is how to create a filename using the regex. In a way I should replace the tags with the information. I could do that using regex.replace and another regex, but I feel it's a big weird doing that and it might be a better way.
[Edit] Maybe I wasn't really clear in the first go, but the idea is of course that the user (in this case an admin that will know regex syntax) will have the possibility to modify the form of the filename, that's all the idea behind it[/Edit]
I would like to be able to extract a number from within a string formatted as follows:
"<[1085674730]> hello foo1, how are you doing?"
I'm a novice with regular expressions, I only want to be able to extract a number that is enclosed in the greater/less-than and bracket symbols, but I'm not sure how to go about it. I have to match numeric digits only, but I'm not sure what syntax is used for only searching within these symbols.
I was wondering why some of the implementations were not working. In fact, the only one that did work was the one described by Matthew Flaschen. But that captures the symbols around the number as well as the number itself. I would like to only capture the number that is encased in the symbols and filter out the symbols themselves.
I want VB.NET regular expression for below format 7966-591739 I mean user must have to enter 4 numeric characters first then "-" and then 6 numeric characters after that optional for numeric as well as for characters. In my case user can also enter

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][,]).*$
Does anyone have a regurlar expression available which only accepts dates in the format dd/mm/yy but also has strict checking to make sure that the date is valid, including leap year support?
I am coding in vb.net and am struggling to work this one out.
I'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 want to display a phone number in a text box like this:
"(828) 524-5121".
In VB6, I could do this:
temp= Format("8285244121", "(###) ###-####")
and temp would be "(828) 524-5121".
If do this in VB2008, temp is "(###) ###-####".
I may have a string for example potato in a vb.net application. I want to find all the occurrences of o and convert them to 0, so the desired out is: p0tat0.I know it can be done by the provided string operations but I need a regular expression in my scenario.
View 1 Repliesjust as the question says. I get numbers like 2125550938 or 20298277625552. these should change to (212) 555-0938 and (202) 982-7762 x 5552 respectively. this is in vb.net
View 4 RepliesI have a field defined as string for phone number which in my SQL cast to Integer.
Format the column as follows
DataGridView1.Columns("ContactPhone").DefaultCellStyle.Format = "(###) ###-####"
This works as expected for cells with a phone number but for cells without a phone number I get
{}- Which seems like the proper output for what I specified.
is it possible to format cells with no data (no phone number) to show up empty in their cell?
I'm trying to validate the correct format for a phone number in a text box: (000) 000-0000 For a test, i made it so that a messagebox shows up saying "correct" if the format is correct. This test works well WHEN the format is correct. BUT when the format IS NOT correct, I keep getting an error saying that the index was out of the array.

i'm trying to make the regular expression for validations, but I can't manage to get a control of the result I want.
I wanna input in a textbox the following :

How can I manage it??

I can get it to work in VB.NET but not C#. I can't figure out why it works in one but not the other.

As far as I can tell the patterns are identical in both languages with escaping. When I run the VB code I get a match. When I run the C# code I get nothing.
I have just coded the below regular expression. I have a mini rich text editor on a web page (very similar to the one I am using to post this question) and I want to make use of a double asterisk to indicate which words/phrases should be wrapped in a strong tag.

Maybe I am over-optimising this, but I want to know if this can be made more efficient?
It is a little like a search and replace, I want to replace any string that contains any substring in parentheses with the same string but the words in parentheses colored RED: Eg
Take this text in TextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
and convert to this text in RichTextBox1:
"The Prime Minister (that idiot from Scotland) made a speech today"
