I have to include math symbols in my asp.net
so whatever the symbols it may be sigma , integral , pie etc..or any
how to write or display the Symbols in asp.net it should be UI so when the user click the
particular Symbols it will display in the textbox or any editor control..
If anyone have idea let me know...?
thanks.
Since you are using ASP.NET you can use the HTML character entity references to display symbols.

You can just put the special characters into your html code. Prefix the items from the reference with "&#" and suffix with ";"
∫ dy K(x,y)φ(y) = λφ(x)
yields
∫ dy K(x,y)φ(y) = λφ(x)

Just wondering if anyone knows how to add Unicode input in pluto.jl. For example, if I want to input a Unicode character for sigma, I would type \sigma in vs code, and the autocomplete will change it to σ. Any ideas how I could do the same in pluto.jl
You should be able to do the same in pluto: type \sigma, then hit TAB and it should change to σ.
I have written a plain text in notepad editor. This text contains some embedded mathematical formulas like \sumw_if(x_i) which refers to \sumw_if(x_i) or \alpha^2 + \beta^2 = \gamma^2 which refers to \alpha^2 + \beta^2 = \gamma^2etc.
Now, I'm looking for a way to autocorrect all those formulas within ms-word. First I tought to select formulas one by one and then "ALT +" to get the maths notation. This method works fine but it's frustrating because I have a bunch of equations
Is there any help? Macros, MathML or other tips?
Regards
If the embedded mathematical formulas were delimited with dollar signs -- e.g., $\alpha^2 + \beta^2 = \gamma^2$ -- MathType can do it with its Toggle TeX feature. If it's something you want to do programmatically, there's the MathType SDK.
When I mark a string within a php file and then type a ', ", ( or [, then the marked text will not be replaced by the typed in character. Instead it well be enclosed by '…', "…", …
I know this is a feature, of course. But I want to turn off this feature because I don't like it. Can you tell me how?

This used to drive me crazy too, but it has grown on me.
I am creating a website for creating test papers for maths , physics etc, as it is not accepting special symbols.
(1.) If sin(symbol theta) then the general value of is
(a) 2n(pie symbol)
(b) 4(pie symbol)
(c)
(d) None of these
I have done rest all but it is taking only simple text questions , not symbols.
How to do that?
A quick search on Google lead me here: http://barzilai.org/math_sym.htm.
So, instead of typing the word, or trying to copy in the symbol from whatever text editor you are using, simply copy in the little set of characters from this website, and it should show the character in the website.
Here you see a conversion table http://htmlhelp.com/reference/html40/entities/symbols.html
Usage
You can just use it in your HTML, for instance
<div>This is the capital letter phi: Φ</div>
We need to restrict user input in a classic ASP web site to the characters allowed by the 00280 code page of IBM System i.
Is there a way to do it in a sane way besides having a (JavaScript|VBScript) function checking every character of an input string against a string of allowed characters?
A basic classic ASP function I thought of:
Function CheckInput(text, replacement)
Dim output : output = ""
Dim haystack : haystack = "abcd.. " ' Insert here the allowed characters.
Dim i : i = 0
For i = 1 To Len(text)
Dim needle : needle = Mid(text, i, 1)
If InStr(haystack, needle) = 0 Then
needle = replacement
End If
output = output & needle
Next
CheckInput = output
End Function
Would - in my function - a RegExp be an overkill?
The short answer to your first question is: No. To your second question: RegEx might not help you here because not all RegEx implementation in browsers will support the characters you need to test and neither does VBScript version of RegEx.
Even using the code approach you are proposing would need some very careful thought. In order to be able to place the set of characters you want to support in as string literal the codepage that you save the ASP file would need to be one that covers all the characters needed or alternatively you would need to use AscW to help you build a string containing those characters.
One slightly simpler approach would be to use Javascript and have the page charset and codepage set to UTF-8. This would allow you to create a string literal containing anyset of characters.
Since it is generally not considered secure to rely on browser validation, you should consider changing your IBM i (formerly OS/400) application interface to accept UCS-2 data, and perform any necessary validation and conversion at the server side.
