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)
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?

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.
View 1 RepliesIs there a way to perform a mathematical equation on a field which has been EVAL'd in a gridview?
[Code]....
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 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 recently upgraded to Windows 7 64 on my development machine. I am trying to setup my development environment. I have discovered something strange. When trying to set breakpoints in my ASP.Net application the breakpoints will only work if they are in the root folder. My ASP.Net project has various sub folders and any breakpoints in code that is stored in the sub folders turns yellow when debugging starts and states breakpoints will be missed.
I have deleted the temporary folder in c:windowsmicrosoft.netframework .... etc. etc. etc. I have checked the folder permissions in the root and all sub folders (they are the same). I have deleted and rebuilt the subfolders. I have right clicked VS2008 and said to run as administrator. Nothing seems to fix it. I can debug root level code behind pages but anything stored in a subfolder will not debug.
Quesion 1:
How to check if a string str1 has at least one of such symbols: ~#$%^&*()[]{}@
Is it possible to solve this quesion using Regex? Any smarter way than this:
If InStr (str1,"~") or InStr (str1,"#") or Then End If
Question 2:
How to check if a string str1 consists of any combination of such symbols without any other symbol: ~#$%^&*()[]{}@
I have created a website in ASP.NET 3.5 that takes some input in text format and saves it in a SQL Server 2005 database.
The database field is varcahar(50).
But I can't do it if data in text box contains special symbols like <,>,#,@,.
It generates a client script error showing security error.
For scripting I am using JavaScript.
Special symbols are a real pain to learn about because you can't Google for them (try doing a Google search for "<%#" and you's get nothing).
I've been a programmer for many years, and I'm trying to get my head around ASP.net, and especially the "special symbols"; what they mean, where to find out more information about them. Because they're impossible to search for, it'd be wonderful if there were special resources in place to help newbies learn about these.
Specifically, I'm looking for detailed instructions on the porpose for, and use, of the following constructs:
<%@ %>
<%$ %>
<%# %>
<%= %>
What is expected in each, what is allowable in each, and what "gotchas" would a newbie have to be careful for when employing each.
For example, I want to do some coding in a <%# %> block, like:
Text="<%# if (Eval("InUse")) {Eval("ProductName")} else {"Not In Use"} %>"
-- would this be allowable, and if not, what are reasonable alternatives?
I get following code (no server error, no html tags nothing... what I am copy pasting is FULL source code).
[Code]....
This goes on in several lines, no eed to repeat it all. There are no html tags, no server error... nothing. It happens on 3 pages, and only common things they have is a texbox TextMode="Multiline"... on first 2 it helped if that text area was empty or without any strange characters.But on 3rd one, I am simply raising postback from a checkbox to display or hide a corresponding textbox... so no data is being sent nothing..... I am totally baffled with this...
Edit: This happens on 2 IIS server (my local machine and other remote IIS that I use) but Cassini actually gives me a message error!
I had an issue when I began working on my project, see this thread where I couldn't debug my DLL's. All I had to do to solve it, though it took me forevever to find this, was to hit F5. This doesn't make much sense since they are DLLs and I get a message that I can't run them directly, but whatever, it works. The output is generated as debuggable and I can copy it to my deployment directory and run and hit BPs (I attach to aspnet_wp).
My VS solution is four projects, all are DLLs, and one is called directly by my web application and it calls the others. There are two I am interested in debugging as I am enhancing them.
Maybe I jinxed myself, but I was actually musing recently that if I never figured out why I couldn't debug I'd never have progressed as much as I had in my task. Yesterday I backed up my project to a zip file - source and DLL's - because I was starting on a new piece. The only thing I did to the solution after that was move a module from App_LocalResources to App_Code, then I moved it back. And I added some code. When I tried to set BP's the next time I ran, I got "symbols not loaded". I haven't been able to debug since. I tried restoring the zip file since yesterday I could debug, but I didn't hit BPs there either. I will be researching this the rest of the day, I am sure, but I thought I would ask for specific since maybe I can tell you something that will you to know what I did wrong or you can throw out a question that will trigger to me what I am doing wrong. This is really not how I wanted to be spending a Friday.

How to force strictly 10 or 12 symbols?
I hate VS and this symbolic gibberish that never seem to have same solution (if it once was logic) twice. The screendump below says what it says.
As soon as I F5/Start the web project, the breakpoint going yellow. This ONLY affect the aspx.cs file that being changed. The other aspx.cs files can have breakpoints.
When I do rebuild/build all DLL and PDB files are created just fine. They have same compile time and are in same directory. Module-Windows i VS says the symbols are loaded perfectly. Well, yeah, try bite me!
I can tell, all symbolic is working just fine, until I was about doing changes inside those aspx.cs files (which was some time ago since last time). If I reset back the file, the breakpoint are working. If I try to make changes in another file, the problem appears there.
It simply appears like that the symbolic file generator don't understand changes maded in aspx.cs files..

Some days ago all of my projects started working crazily - I'm using VS 2010, .NET 4.0, Silverlight 4 SDK, WP7 SDK. The previously compiled code parts can be debugged as they should be, but as soon as I make any change to the observed .cs file all symbols are ignored.
"The breakpoint will not currently be hit. The source code is different from the original version."
However, the compile is successful, moreover the changes in the code can be seen in the debug mode as well (e.g. if i add messagebox.show(...) it works as expected), but I'm unable to debug the project.
This happens to my Silverlight, WPF, WP7 solutions, Web Applications, so everything important. The most annoying thing is that I even reinstalled Visual Studio, the whole .NET Framework 4 Client Profile, but nothing changed.
I don't want to reinstall the whole OS, but this way i'm unable to work:/
