What is the regular expression for a RegularExpressionValidator so it fires if the string in the validated control contains a r is longer then 250 chars?
View 1 RepliesI want to convert a string to a number.
But some strings have a normal char in it like:
543p
How can delete all chars, instead of all chars that are normal in a decimal ?
I'm trying to complete a regular expression that will pull out matches based on their opening and closing characters, the closest I've gotten is
^([[)[a-zA-Z.-_]+(]])
Which will match a string such as "[[word1]]" and bring me back all the matches if there is more than one, The problem is I want it to pick up matchs where there may be a space in so for example "[[word1 word2]]", now this will work if I add a space into my pattern above however this pops up a problem that it will only get one match for my entire string so for example if I have a string
"Hi [[Title]] [[Name]] [[surname]], How are you"
then the match will be "[[Title]] [[Name]] [[surname]]" rather than 3 matches "[[Title]]", "[[Name]]", "[[surname]]". I'm sure I'm just a char or two away in the Regex but I'm stuck, How can I make it return the 3 matches.
I am using a RegularExpressionValidator in my code as follows:
<asp:RegularExpressionValidator ID="rev1" runat="server"
ValidationExpression="[a-zA-Z0-9]{5,7}"
ControlToValidate="txtTAM5" ErrorMessage="Please enter a valid value." SetFocusOnError="True"
Display="Dynamic" ValidationGroup="vg1"></asp:RegularExpressionValidator>
I am trying to use a RegularExpressionValidator for email ID text box. Everything works fine till I add an AJAX TextBoxWatermarkExtender for the same text box. I have given the WatermarkText="Email" for the text box. When I push the submit button, the RegularExpressionValidator fires and says Invalid Email ID. When I clear the same text box, no issues and the records are saved.I strongly suspect that the RegularExpressionValidator is taking the text of the watermark, ie "Email" as an invalid email ID. To test this I gave the text as "someone@website.com" for the TextBoxWatermarkExtender and it did not fire the RegularExpressionValidator.
View 5 RepliesI am having trouble with parsing a srtring, let me figure out :
This is my string (being gathered from DB) : students/notes/8293/location/michael.jpg
and i want to parse "michael.jpg" from this string to be able to process it.
I have a textbox to which i want to allow only digits and chars and restrict any special chars.
So if i use the following javascript it works fine:
[Code]....
But the above does not work. It allows special chars also.
I have a string and I want to know if it has unicode characters inside or not.(if its fully contains ASCII or not)How can I achieve that?

In my project one of scenario demands passing querystring values more than 256 chars @ a time ...I tried it but after 256 chars its trunacting all other chars. workaround or various ways for passing more than 256 chars through querystring.
View 6 Replieson my page i have a time range printed in the format of 12:00 AM - 12:00 PM i have to display this appropriately for whatever culture the browser supplies. i'm having an issue with arabic (ar-ae): the am/pm indicator seems to change the text ordering for part of the string. the string has the right characters in the right places in memory, but shows them in a different order.
so for my start and end times, i have strings like 03:00 ص and 11:00 مand then i put them together like
string dummytext = t1string + " - " + t2string; when the page is written, the range is displayed as 03:00 ص - 11:00 م i've tried putting each piece in a Label control and wrapping everything in a div with dir="ltr" and haven't made any progress. this is happening in a table cell if it makes any difference.
I have a htmlarea (Jquery plugin) where I need to accept longer strings than 2048 which seams to be the limit. I don't have a clue where to look. It's an MVC app and here are the relevant code:

<% Using Html.BeginForm %>
<%: Html.TextAreaFor(Function(model) model.PageText, 30, 30, New With {.style = "width:800px;"})%>
<% End Using%>
<button id="SavePageText">Spara</button>
</div>

$(function () {
function SaveText(pageID, htmlText) {
var retvalue = false;

i have a problem in string manipulation
here is the code
string str = "LDAP://company.com/OU=MyOU1 Control,DC=MyCompany,DC=com";
Regex regex = new Regex("OU=\w+");
var result = regex.Matches(str);
var strList = new List<string>();
foreach (var item in result)
{
strList.Add(item.ToString().Remove(0,3));
}
Console.WriteLine(string.Join("/",strList));
the result i am getting is "MyOU1" instead of getting "MyOU1 Control"
I need to find a regex that tests that an input string contains exactly 10 numeric characters, while still allowing other characters in the string.
I'll be stripping all of the non-numeric characters in post processing, but I need the regex for client-side validation.
For example, these should all match:
1234567890
12-456879x54
321225 -1234AAAA
xx1234567890
But these should not:
123456789 (not enough digits)
12345678901 (too many digits)
I am getting taggings like the following in a string
<color> vocation </color>
<color> elation </color>
<color> sage </color>
you can notice that each tagging differs only in the wordings
vocation
elation
sage
But i want to write a code some thing like this
Regex.Replace(userAx, "<color> vocation </color>",
"<color> </color>"
so that the resulting output does not contain words at the centre.In the above code instead of giving the word vocation exclusively, i have to mention some pattern, so that it will replace all the words instead of doing it for first sentence only.How to modify my code?
I am trying to get all the words in a string using a regular expression.When I use this expression in javascript, it works, but when I try it in the .Net code I get the whole string.this is my code.Is my regular expression wrong or am I using the wrong method?
Code:
Dim myRegex As New Regex("/([a-zA-Z]){1,1}([a-z])+/g")
Dim str() As String = myRegex.Split(text)
I am trying to check if a string ends in "@something" and extract "something" from it if it does. For example, I am trying to do something like this:
string temp = "//something//img/@src"
if (temp ends with @xxx)
{
string extracted = (get "src");
...
}
else
{
}
How can I accomplish this?
Possible Duplicate: Regex.IsMatch vs string.Contains Which is faster, preferable and why?What the difference in mechanisms between two?I need to search for some values from UserAgent, most of values can be used without wildcards (e.g. if I want to catch cellular phones I search for iPhone instead of *iPhone* wildcards).
View 1 RepliesI am using the following code for extracting a number from string 'sentence'.
Regex.Split(sentence, @"D+");
For Ex: This is test , message contains 192837 and the message ends here.
This output would be 192837.
Now, Let say: sentence is: This is test, 2736 message contains 293743 and message ends here.
This output would be 2736293743.
But, I want only 2736. i.e The first number in a string omit rest all others.
How to deal with this?

I have a table Books with columns BookID, BookSummary, BookAuthor.
What I have stupidly done was to add a link to another url at the end of the BookSummary. Assuming the text is something like this:
This is a book about a love story in World War 2 in Europe. The book is written by Elliot James.
I have added
<a href='http=://XXXXXX'>Buy Book</a> at the end of the text making the final content of BookSummary to be like:
This is a book about a love story in World War 2 in Europe. The book is written by Elliot James.
<a href='http=://XXXXXX'>Buy Book</a>
I now need to write a code (via regex?) to read through each BookSummary, find the <a href='http://XXXXX'>Buy Book</a> and delete it. But the problem is the content in XXX could be anything and I cannot use typical string functions. Can anyone guide me to
achieve this using Regex?
What's the regular expression to check if a string starts with "mailto" or "ftp" or "joe" or...
Now I am using C# and code like this in a big if with many ors:
String.StartsWith("mailto:")
String.StartsWith("ftp")
It looks like a regex would be better for this. Or is there a C# way I am missing here?
I want to write a Regex in DataAnnotations that can unmatch a input string containing not paired double quote " ie. check if zero or a paired double quote allowed in a input string.
matched case:
abcde
"abcde"
abc"d"e
unmatched case:
"abc"de"
"abcde
abc"de
abcde"

I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.
