How can I make this regex not accept spaces?: [0-9a-zA-Z' ']{3,}
Everything I'm reading says to put a * or a + after the [] , but I get an invalid expression error when I do. The end result I'm looking for is a string of letters and numbers only - no spaces inbetween.
am using this function to remove whitespaces at html output. i had to put if else otherwise page was giving error afterasynchronous postbacks. now it works fine.is it possible to make it work also after asynchronous postbacks ?also is it possible to make this regex function also removes new lines ?like how google doesthere is no line at their source codes

I would like to use a regular expression in C# to turn any two or more spaces into non-breaking spaces. I would like to leave single spaces alone.
Sample Sample
Would produce
Sample Sample
But
Sample Sample
Wouldn't be affected.
I am looking for a regular expression for c# asp.net 3.5 that will fail if there are ever any double spaces in a sentence or group of words.
the cat chased the dog = true the cat chased the dog = false (doubles spaces occur at random intervals)
I need to calculate the number of free spaces between two characters.Consider the following Example
tring str = "This is the sample" ;
I need to calculate the spaces between "This" and "is"
als find the spaces between "is" and "the" How to find it?
How can I write regular expression in C# to validate that the input does not contain double spaces? I am using Regular Expression Validation. However I do not know what is the Validation Expression to get the result.
"white snake" : success
"white snake" : fail
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 have an application where the user uploads files.
GOAL:
I need to check the file name for special characters and replace them with an underscore. Is there a Select Statement OR IF Statement I can use to search the fileName for unwanted special charaters; those characters will be replaced with a blank or underscore?
I want to replace ampersand, Number sign, Apostrophe, and so on.
My Question is as follows:Using ASP.NET syntax for the RegularExpressionValidator control, how do you specify restriction of two consecutive characters, say character 'x'?
View 4 RepliesI'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.

View 3 RepliesI've finally figured out an issue I'm have with a zip code field being entered in a text box of a details view in edit mode. I'm trying to understand why i have the issue though. I don't understand why it keeps occurring.his what happens with the zip code field. I've been able to make it reoccur numerous times. If the details view is put in edit mode and the record is updated with the original 5 digit zip code, unaltered in any way, my regular expression validator catches it and doesn't let the update happen. If I change the replace the 5 digit zip code with a new one the update goes through fine. This new value can be a different or the same 5 digits and the update will work. If I don't change the value at all though the update will not go through.
