Web Forms :: Parsing Textbox.Text With Regex Query?
Aug 22, 2010
I have the a text box into which I paste the following text:
England has 80 skyscrapers, 2405 houses, 0 spaceships
I want to parse the contents of this textbox and extract the integers to variables eg:
[Code]....
I tried the following regex but It doesn't work:
Dim skyscraper As
New
Regex("/([0-9,]+) skyscrapers/")
Any pointers as to what I should be doing?

I have 2 tables A and B. Table A has a text field, fundIDs with comma delimited values like 23,44,55 etc. I would like to select all the records in table B whose ID matches the values in the fundIDs field from only one record in Table A. So, I need a function which first gets 1 table A record and uses the fundIDs field values to query and return all the matching records from Table B. I don't know how to parse and query in sql

I'm tyring to write a simple DetailsView only used for inserting new records that will pre-fill a textbox with a query string value. Here's the DetailsView:
[code]....
All I want to do is set VenueID_FK.Text to = the "VenueID" querry string. I also want the user to be able to see the VenueID number as they are filling out GridView1.
I know this is probably a simple thing, but I am very new to asp.net. I thought I could handle this in the page load event, but when I try something like this
TextBox VenueID_FK = (TextBox)DetailsView1.FindControl("VenueID_FK");
And then follow by setting the Text property programitically. I've accomplished something similar to this on a different page using a FormView, but only for ReadOnly mode and it was handled in the databound event on that page.
I get the error "The name 'DetailsView1' doesn't exist in the current context." when trying to do the above mentioned. When trying the same line in the databound event here, I get the same error.

I'm developing my own forum, and now I've come to the task of replacing text with smileys (such as colon and left parethesis to a smiling ball). this works well with the Replace function, such as
dim smile as string = "<img alt=""smiling"" src= ... "
txt = txt.Replace(":)", smile)
myLabel.Text = txt
However, I'm worried about speed, because this approach means running Replace on every message a bunch of times (each for each emoticon, quote amrking etc). Is there a smarter way to do this, or is this the reason why forums are, in eneral, so slow?

I am trying to add some widget-functionality to the CKEditor using custom plugins.. Does anyone have any experience parsing the resulting html or getting the job done in another way?
What I am looking for is to add something like a news-block at a user specified place in the text, like an ordinary image..
I have thought of several options, like just adding an iframe that takes care of the content automatically (from the src url in the iframe), but that way I loose the text formatting/css.. I have also thought of adding the content dynamically with some ajax onload, but that way I might loose some viewers..
Finally I have come to the conclusion that using custom tags like <something options="..." /> or even <div class="something" options="..."></div> and then replacing them with usercontrols is the best solution.. But how to accomplish this? I know how to add controls to other servercontrols, but how to add them easily in some random text? It could be something like putting the text prior to the widget and after into a placeholder and adding the widget-control in between..

I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

I want to find a substring (email) in a large text using Regex.
just want to return the first valid email that is found from the input text:
example:
string inputString = "Our email is myname@ourcompany.com.
desired output: myname@ourcompany.com
this is the Regex pattern i've used: ^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$
- is this pattern correct?
Code:
private static void DumpHRefs(string inputString)
{
Match m;
string HRefPattern = @"^[A-Z0-9._%+-]+@[A-Z0-9.-]+.[A-Z]{2,4}$";
m = Regex.Match(inputString, HRefPattern,
RegexOptions.IgnoreCase | RegexOptions.Compiled);
while (m.Success)
{
Console.WriteLine("Found email " + m.Groups[1] + " at ".......

If the selected text is "srodkiem ", is it possible to get the relevant span tag?
Is this possible using a regular expression?

I have code like this
string pattern = "<(.|
)+?>";
System.Text.RegularExpressions.Regex regEx = new System.Text.RegularExpressions.Reg(pattern);
string result = "";
result = regEx.Replace(htmlText, "");
In this "htmlText" will have some html code which also contains break tags. Right now its replacing all the html tags, but I want to leave break tag and replace the rest.

I have a table being brought in using HttpWebRequest (screen scraping). The table I grab is formatting properly but I have noticed a situation. This table has a URL which refers to a physical web page. What I would like to do is to take that URL using a .Replace clause and thereby change the URL to reflect <a href="details.aspx?id=111"> as opposed to <a href="111.htm">. So I went ahead and tried doing it this way but it doesn't do any replacement.

I figured using the regex expression it would find it and then I could just reuse it.

Background: I've wrote a small library that is able to create asp.net controls from a string.
Sample text:
Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. At vero eos et {{asp:hyperlink|NavigateUrl="/faq.aspx";Text="FAQ";}}{{codesample|Text="FAQ";}} accusam et justo duo dolores et ea rebum. Stet clita kasd gubergren, no sea takimata sanctus est Lorem ipsum dolor sit amet. Lorem ipsum dolor sit amet, consetetur
I've expanded the code with some reflection to gain full flexibility to be able to render WebControls and UserControls. Works fine so far, for every usercontrol I've tested. I'm now facing the problem, that the parsing for my property key-value is not flexible enough to support arbitrary multine content.
This is part of the code that I'm using for the string operations:

My current script is stopping at "Geography - Higher - A1" I need to get to next line.

I have a page with a text box, a button and a GridView. Enter an account number in the text box, press the check button and the result will show in the GridView.
Now user wants that if the text box is clear, the GridView disappear.
I can only find TextBox1_OnTextChanged. But I want to have that while the user is clearing the text, if the length of text becomes zero, the GridView is clear out. So I am looking for OnTextChanging(). Well of course this function does not exist. How to achieve the same purpose?

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.
I was trying to follow this tutorial on msdn, but it doesn't quite fit perfectly with my problem:

I have what I think is a weird issue. I send text from one page to another via Session Variable. When page 2 loads, the text box has the session text set, but if the user changes the text and clicks the button, the SQL database is update with the original session text. If I remove the redirect from the page 2 button_Click method, then, the page refreshes with the textbox reverting to the session text and thr SQLDataSource has the session text added to it.
