if there are two consecutive apostrophe or two consecutive hyphens or two consecutive comma or two consecutive spaces or two consecutive periods or two consecutive periods..I want to display those particular error.
and One more thing is if there are any of the above combinations like apostrophe+hyphen or apostrophe+space or hyphen+space, I want to throw that specific error.
I think it can be solved by Regular expressions but maby I'm wrong. I upload a .html file which is saved from a webbrowser. I read the stream and with Stringbuilder I make a string of it.But now I want to have only the data which is in this div:
I have two the below regular expressions for a textbox , to validate.
^(([01]?dd?|2[0-4]d|25[0-5]).){3}([01]?dd?|25[0-5]|2[0-4]d)$ - Validation Expression For IP Address ^(([a-zA-Z0-9]|[a-zA-Z0-9][a-zA-Z0-9-]*[a-zA-Z0-9]).)*([A-Za-z]|[A-Za-z][A-Za-z0-9-]*[A-Za-z0-9])$ - Validation Expression for Host name
I want to use both these for the same textbox, It should fullfill either of these conditions. What should I do so as to satisfy my condition.
I am trying to search titles in this pattern a text. the titles are unknown and sometimes it contains special characters '(' and ')'.... when this is happens the only way to make the match correct is by replace ')' by ')' . is there a way ignoring this replacment? and if not, what are the complete meta(special) characters?
I want a limited amount of html tags for the user to be able to put in my form and by looking at the posts, regular expressions seem to be the way forward. I don't want to use javascript or 3rd party as this is for an assignment at university.
The examples I have found seem to be set out differently than mine with using asp id identifiers whereas my code below is set out differently so I am unsure if I can use these examples.
I am building a forum and I want to be able to use simple square bracket tags to allow users to format text. I am currently accomplishing this by parsing the string and looking for the tags. It's very tedious, especially when I run into a tag like this [URL]. Having to parse the attribute, and the value, and make sure it has proper opening and closing tags is kind of a pain and seems silly. I know how powerful regular expressions are but I'm not good at them and they frustrate me to no end. I think an example would get me started. Just a regex for finding tags like [b]bolded text[/b] and tags with attributes like the link
I applied regular expression validator on date of birth and Missing date for a missing person. the missing date should be greater than the date of birth . I applied compare vallidator but it is not working properly. it comparing day of date of birth with day of missing date, both months and years...
I am getting ready to just write my own, but I have a need for some regular expressions that will validate strings to make sure they are in an acceptable format to be inserted/updated into a database field. I figure it may just be to find a list of them someone has already posted somewhere and just use those.
I have a website created in asp.net and have the following fields displayed in the grid view linked through a database.First_Name Last_name City Username Password Email Mobile Genderplease let me how I can put validations when the edit button is clicked and the textboxs popout...I have tried a lot of ways like edit template and all but they have not been helpfulReallyIf you need I can also post the code I am using..
I am trying to find a way to limit the inputs on a webpage to a variety of different sequences, and although I have worked through the regular expression library, I am still confused on how to allow decimal places and a maximum value. I initially used rangevalidators, but as you know, these only limit the inputs to a range, and have no control over the decimal places entered. A variety of limits i have been asked to implement are:
1. Range 0-45, 0 decimal places 2. Range 0-20, 2 decimal places 3. Range 16-65, 0 decimal places 4. Range 0-99, 2 decimal places 5. Range 0-1500000, 0 decimal places 6 Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used ([0-9]|[0-9]d|45)$ ([0-9]|[0-9]d|1500000)$
but want to be sure that I have understood the pattern correctly. How do I then go about creating a pattern for the other examples?
I have a ListBox that contains userNames which is inputted by a user during run time. This number of items in the ListBox is dependent on the user's input. These userNames will then be used in a Lambda expression like this:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName"));
This works fine when there is only 1 user in the ListBox but doesn't produce the correct results when there are multiple items in the listBox. I tried manually creating the expression which should be written as this:
I tried forming the "a.UserName.Contains("userName") expression as a string which is dependent on the number of the items (using foreach) and then just plug in the resulting string in the expression but it seems that it doesnt accept string as an expression.
I'm bulding document-from-template engine. At certain points I need to match on Reg Exp groups and replace template text with content from a db.
I 'hardcoded' my RegExp initially, doing something like: Regex r = new Regex(@"{DocSectionToggle::(?<ColumnName>w+)::(?<ResponseValue>.+)}[[(?<SectionContent>.+)]]", RegexOptions.Multiline);
it does group capture, so the syntax isn't the prettiest.
Just to make things neater and because I want' to keep the patterns in web.config or elsewhere, I've 'evolved' algorithm to something like:
[code]...
But I'm getting an error: 'Input string was not in correct format'.
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'?
I have a button on my web page and i would like to know if its possible to aviod consecutive clicks. Lets say i have a submit button or another button which inserts into db. And i figured out that there are two records in the db. So i would like to avoid consecutive button clicks.
I have a textbox and button in my child page it inherits a master page.the textbox should allow to key in only alphabets,comma,dot,space,single quote. And also consecutive comma dot single quote should not be allowed to key in. first and last character should be alphabets.
I have a javascript but it does not check for consecutive comma,dot,single quote...
I am want to develop a quiz site using MVC 2. A single page will display only one question. The examinee will select or type the answer and press Next button to proceed.
My business logic on the server side will record the time elapsed between two consecutive page requests. This time elapsed must not be tempered by any means to make a reliable diagnostic report.
