Any open source javascript mathematical formula editor to recommend? I want to add mathematical formula editor to my web site, so that when people submit message using text box, they can insert related mathematical formula.
BTW: I am using VSTS 2010 + C# + .Net 4.0 + ASP.Net + IIS 7.0, any such controls provided by MSFT?
We have one new project to implement. Let me explain briefly about this project. This project is related showing chart to end user on the basis of different mathematical calculated formulas.
End user has authority to change these formulas on the fly and on the basis of that changed formula we need to show the chart. So this is all central idea about the project. These charts which I mentioned above are very complicated and user friendly
So can any buddy tell me which is best suitable architecture for this and how can fit her to my scenario .I knows, three tier architecture and some other are there but I want know which is the best architectures that developed above idea in right way

I went through the documentation and looked at the asp.net/webmatrix pages but could not find a RichTextEditor.
Is there one built into WebMatrix or can I just use the AjaxToolkit Html Editor or another 3rd party editor?

View 1 RepliesI'm using an asp:TextBox as the wmd-input. As the user clicks the submit button I wan't to capture the markdown at server side as the Text property of my asp:TextBox control. However, instead of the expected markdown, my TextBox at server-side contains the HTML formatted version of the markdown: <h1>testing</h1>
How do I get the pure markdown? PS: At client side I see markdown on the asp:TextBox. It's not clear for me when it's getting converted to HTML before post-back.
IS it possible to use mathematical symbols in asp.net application.
I am developing a online assessment web application. In that I need to use mathematical sysmbols as question and the user also should be able to use that symbols.
Is it possible? Is any other third party editor is required?
Can I store that symbols into MS SQL database?
I am looking into the possibility of shortening / encrypting a url which will be from 150 to 250 characters in length to maximum 12 characters using an algorithm. Initially I am doubting it's possible but I wanted to leverage the great minds of StackOverflow :)
the algorithm should be one that can be written in classic asp, sql, c#, vb, or foxpro or other language.
Is that even possible without a database centric approach?
I was reading here that AES in CFB mode, will do a stream cipher and the output length will be the same as the input length. Is there any way to shorten it even more?
I'm new to .NET and converting and proper way to convert strings to other values. Specifically, here is a situation I'm facing:
I'm returning two values from a datasource as strings. One values is a representation of a span of time, and another is a count of how many attempts to access a system took place within the span of time.
Given these parameters (for example):
Span of time: 00:01:00
Attempts: 13
I'd like to calculate a third value that shows how many seconds each attempt to connect took place during that span of time. This involves converting the time span to seconds and then dividing by attempts. Where I am getting lost is with the conversion of types. I know the span of time needs to be converted to a date, reduced to seconds, then converted to a number to be divided by the attempts field, also converted to a number.
I've been playing around with code segments like this all morning to no avail:
VBNET Code:
Dim thisTime As String = "00:01:00"
Dim thisAttempts As String = "13"
Label1.Text = thisTime
Label2.Text = thisAttempts
Label3.Text = Math.Round(Integer.Parse(Convert.ToDateTime(Label1.Text)) / Integer.Parse(Label2.Text), 2)
Is it possible to perform mathematical operations within a .aspx View.? for example..lets say i have a total number of pencils of say 100. and i have 12 students on a data table with his or her name, and the number of pencils she has
Student Name: Pencil #
John 10
Sarah 12
Linus 19
But while rendering the view i want to calculate the Percentage of pencils one student possesses out of the total. (John would have 10% of the total 100 pencils)
How would i just perform this basic math operation, and encode the result into the view. I know i need to store the 100, and divide by each count of pencils for each student within the foreach loop. but i keep getting 0. This seems very elementary i know.. Help would be very appreciated. Google seems to have nothing for me.
how you have implemented mathematics type captcha in comments sections in URL...I like to implement this type of captcha security, its more clean and user friendly.

I have an Editor control on my page and the user can go in use it hit save and that all works.
In another part of the page I have a simple dropdown to select a note and view it. When you push view it loads the text which was entered in via the editor control.
If the user used an order or unordered list. The text shows up but not the list part.
So if they did this:
Example
ThisAnd this
What is displaying is
Example
This
And This
Without the bullets. Same for the numbers.
I have it going to a literal control which should render the html, but it doesn't.

View 2 RepliesI have two textBox, one button and one gridview. In one texbox, I enter a value, click the button to add this entry to the gridview and the footer is computing the sum as i add more entries to the gridview.
I also have a textbox outside the gridview that will hold an amount, now I want to perform an operation like...(txtOutsideGridview - gridviewEntry1 - gridviewEntry2), and display the result of this operation inside the footer of the gridview, instead of the sum. How do I go about doing this?
So far all I have been able to do is sum up the total of entries within the Gridview, but that is not my desired operation...here is what my current code looks like

I was wondering if there was an easy way to change the output generation properties of the HTML editor.
I need to change it from the current XHTML standard (spans, etc) to legacy styles; <b>, <u>, <i>, etc.
i am now think of how to get all the output for all the combination
eg.
given : 1234
output = 1234,1243,2143......and so on.....all 24 possible output
if given : 123
output = all 12 output
if given 12345 , all 120 output...
can someone provide me the algorithm or formula for that ?

'Dim arrDec() As String
I am new to .net having come from a PHP background.I'm making a small website at the moment in .NET. On one page I have a form with a few fields:
1st value (let's call it A)
2nd value (let's call it B)
3rd value (let's call it C)
4th value (let's call it D)
When the user clicks the submit button, it needs to work out the formula:
(A*4)+(B*3)+(C*4)+D+15
What is the easiest way to achieve this in .NET? Is it best to use a 'code-behind' model and have the calculations done on another page then displayed on the next webpage?
