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.
View 3 RepliesI 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:
[Code]....
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 having a set of html tags.

<span class="active"><a href="abc.aspx">Hi thi is titile</a></span>
It will be fine if i get the text in the a tag that is with in the span having the class name "active".
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?
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 take the text of the html of a site and want to select a substring of the whole text. the text is something like this
[Code]....
As I have the URLs like
http://somedomain.com/products.aspx?id=1
and i want to rewrite this like
somedomain.com/productname and rest of the URLs on the domain work as they are provided.
like
somedomain.com/forums/categories.aspx
I don't want to rewrite these other URLs
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?
View 1 RepliesI 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

In the "Regular Expression Editor" dialog in VS 2008 ( or 2005 for this matter ) ,
there is a list of "standard expressions" like :
"French phone number" , "French postal code" etc..
And of course there is an option to select a "Custom" and then enter your own regular expression.
Well.. I want to add a predefined expressions to that list . Like : "Israeli phone number" .
I don't want to enter it every time by selecting a custom value .
I want my developers in the team available items for them to choose.
Anyone knows how to alter that list ?
I've found some question about it on the web - and the answer given is that it's not possible .
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:
var vHandleResult = vHandleResult.Where(a => a.UserName.Contains("userName1") || a.UserName.Contains("userName2") || a.UserName.Contains("userName3") || a.UserName.Contains("userName4"));
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'.
Is this a limitation of string.Format(...)?
using .net 4 and vs2010

I have encountered the task of saving an image to a MsSQL Server Database. (Although I haven't even managed to do it yet).
But anyways I need to link this image from the MsSQL Database to Gridview. Can this be done ?
I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.
I am about to get my sites hosted with a local host company. They are offering me their lowest cost MSSQL server, which is the web edition. So my question is what is the difference between that and 2008 express edition? Can express edition be used for a full fledge in production website? And does Web implies that I will be interacting with it via the web correct. Lastly, if the web version is not chosen what is the typical protocol for uploading and maintaining a site when you have a dedicated server. Do you normally have to go to the data center or is there like a web portal that can be used. I will be asking the guys at the company these questions as well, but I want to make sure I get another opinion on the issue.

View 3 RepliesI was wondering what you guys thinks is the most efficient way to select data from a msSQL database.. I tend to use a sqldatareader, but is this really the best way? - It is particularly impractical if one also must take into account, that the table may be "Null"?:
