I'm looking for a regex that will allow Alpha Numeric and most all special characters except white space. It should be usable in c#. It would be nice if .net supported posix style but I can't seem to get it to work.
View 1 RepliesIs there a way to disallow the asp:Literal from outputing HTML ?
If I input the text <b>Hello world</b> I want to show it just like that, and not in bold.
If possible I don't want to extend it, because I would have to change the whole project.
What is the best way to disallow editing of existing entries in ASP.NET Dynamic Data while it should still be possible to add new entries? If possible, I would prefer a solution without custom templates.
View 1 RepliesHere is my dilema, on my site i have a WordPress Audio player (http://wpaudioplayer.com/standalone) that plays my mp3's.
It loads the Mp3's in by javascript...example below:
AudioPlayer.embed("audioplayer_7", { soundFile: "/Files/Music/[name of file].mp3" });
This file name is clearly visible in the browser source. Not a problem, however this means that any user can legitimately browse to the file directly and download it.
Now i still need the mp3 player (which is flash) to have access to the file but if a user was to try accessing the file directly, they would not be allowed access to it.
I am not sure how to go about this, i am circling the idea of a httphandler but not sure if this is sufficiant to stop the direct access to the file.
How to disallow use of double quotes " in a textbox
View 5 RepliesHow do I achieve this:-When user types character like 'abcd' and then '>'(an invalid character for my application), I want to set the text back to 'abcd'. Better if we can cancel the input itself as we do in winforms application. This should happen when user is typing and not on a click of button.I want this to be applied on all text boxes in my web page. This will be easy if the solution is jQuery based. May be something which will start like this.$("input[type='text']")SOLUTIONI used both of the answer provided by @jAndy and @Iacopo (Sorry, couldn't mark as answer to both) as below.
$(document).ready(function() {
//makes sure that user cannot enter < or > sign in text boxes.
$("input:text").keyup(purgeInvalidChars)

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'm using an asp.net chart control to display a pie chart, image below.

I can't find the property (I assume there must be a property) to get rid of the whitespace surrounding the chart. Does anyone know how to? I feel like I've tried everything...
I want to improve the html output by removing the whitespaces (see quora.com html output). There are a couple of "solutions" out there that do this at the Asp.Net level but those do not work reliable as they do not take the block buffering into account.
Anyone here who has a asp.net mvc 3 solution for that and is willing to share?
I'm rendering a view for the text/plain part of an e-mail. But in some cases, the whitespace is removed between non-output server tags, and I can't figure out why. Can someone explain why the following is missing the line breaks before the final line of output?
[Code]....
But this works - whitespace is preserved between output tags:
[Code]....
This is on MVC 2. It may have been on MVC 1 (or even in Web Forms), but I didn't notice it until today when I went to add a new line to the e-mail, so not sure of the source. Does ASP.NET or MVC have some optimization to try not to output whitespace between server tags?
"something here [tagQuote=Name of Author]bla bla bla[/tagQuote] something here"And now I want to replace all the whitespace character in quote attribute with "%#%#%#%".So I want to have: [tagQuote=Name%#%#%#%of%#%#%#%Author]bla bla bla[/tagQuote]So remove all of the whitespaces between "[tagQuote=" and "]...[/tagQuote]"
View 3 RepliesI'm using the following codeproject to build an asp.net website and so far everything is good. My only problem is after the barcode is generated, a huge whitespace exist to the right of the barcode. I've been playing with this and am unable to resolve it.

Not too sure if the title is the most appropriate description, but I've noticed at the bottom of my page I have a load of 'whitespace' / emptiness where my panel - that is linked to ModalPopup - is during coding / design. Is there a way of this space not appearing when the page is rendered? Setting the panel's visibility to false gives me all sorts of issues and I don't know where to go now to get rid of this annoying space!
View 2 RepliesI am accumulating a string for a SQL IN clause, so the format needs to be WHERE var IN ('string1','string2','string3',etc)
The strings are coming from a multiline textbox where they are pasted in from the user (one per line).
For some reason, I always get a space right after the tick and before the value in every value after the first. For instance my DataReader is only returning one record because the input string turns out like this:
SELECT * FROM Table
WHERE ID IN ('12345',' 23456',' 34567')
Here is how I am processing the string, and I can't see why it is not taking that space out.

Even if I move the replace space (line 2) to the end of the code block, it still wont trim it out...
a)i have an gridview, i need to every record show in every rows, but it's show in both column and rows...., how fix this?i use only itemTemplate in this gridview!
b)how i link a field thats show in gridview and pass to a new page(with query string) for show single record....?
(this is like "read more..." link in many news site!!!)
c)in my db is a 'ntext' field,but when that show in Gridview,all enter(Chr13) and whitespace deleted, how fix this?
Im pulling out a text field from the database which has and 's in it for line breaks. Which I have left there for pupose of being able to edit the fields later on.
So when i try to display the text I need to replace them which I have done with:
[Code]....
Simple enough. Only when I run the page the source code I get for it is:
<br />
So it seems its not encoding the < as a encode but into the form <
Does anyone know how to stop this happen. Or a method around it?
In my asp.net application i have url [URL] to match it i have regex
"~/(.+)" which works perfectly fine. But if i navigate to www.site.com/login.aspx again regex matches with this expression "/(.+)".
In Simple words i want a regex which only match the extenionless url. IF extension is present in the url then do not match it
<RewriterRule>
<LookFor>~/(.+)/(.+)/(.+)/</LookFor>
<SendTo>~/Shop/Item.aspx?cn=&1&it=$2&ft=$3</SendTo>

I need a regex or any other solution to replace an id in the middle of a url (not in querystring).
url example - http://localhost:1876/category/6?sortBy=asc&orderBy=Popular
replace - category/6 with category/anotherID -
routing used -
routes.MapRoute(
"categories",
"category/{categoryID}/{categoryName}",
new { controller = "Search", action = "SearchResults", categoryID = "", categoryName = "" }
);
I try to replace [h2] to <h2> I use this coding:
string o = "<h2>test</h2>";
o = Regex.Replace(o, "[h2]", "<h2>");
o = Regex.Replace(o, "[/h2]", "</h2>");
But the result after the first regex is:
[<h2><h2>]test[/<h2><h2>]
So that is not what i want.
After the first 1, he should make:
<h2>test[/h2]
Whats wrong?

View 9 Replieswith a regex that would replace the following. The only thing that would remain the same is the div tags, the id's and classes could change and so could the content.
<div id="nav" class="whatever">Content is whatever</div>
string lNewHTML = Regex.Replace(lOldHTML, "(word1|word2|word3)", "<a href="page.aspx#$1">$1</a>", RegexOptions.IgnoreCase);
The code works, but I need to include some exceptions to the replace - e.g. I will not replace anything i an img-, li- and a-tag (including link-text and attributes like href and title) but still allow replacements in p-, td- and div-tags.
