Maths Symbols In Windows Form
Nov 14, 2009
I am fairly new to programming so please bare with me. For my coursework, I am making a maths quiz which allows the teacher to add or edit questions and solutions. then these solutions and quetsions form a quiz that students can access.But I dont know how to allow the teacher to use the weird maths symbols. The quiz is only going to be about algebra so no complex symbols are required, I saw some of these symbols in unicode. But dont know how to make that symbol appear in textbox which the teacher is going to use to enter questions etc.

Problem in VisualBasic 10 on Windows 7 OS I have a form which has 30 lines for user input in format <textbox for Name> <comboBox for Type> <comboBox for Quality> <NumericUpDown for Amount> At the start of each line is a CheckBox. The intention is this enables/Disables the line. I have associated each object with an Array - eg
Dim Name(30) As Textbox
etc
and assigned
Name(1)=Name1
[code]....
ie enable/disable the boxes on a line dependent on whether CheckBox is Checked The Sub for Picked_Changed refuses to allow referenced to the arrays within, even if not generated by the picking of box (see above - it allowed '=Men3.Value' but not 'Men(3).Value', although the button sub is fine with this)

I am trying to make a calculator (how original) but I am also trying to make it like a console. I have a textbox in which you enter a command and a list in which the lines appear.
My question is how can I translate the plain text which the user enters i.e 3*(2+4) to a maths command so that VB can display the answer?

I ve done the main main page which includes a button which when pressed will go on the next page etc etc.
The problem that i am facing with is the concept behind creating the main function of the game.
I.e. Once the main screen comes up it will show a formulae eg 3 + 3. After the forumale is shown the user will input the answer and then when they want to go to the next question that click the next button which inturn shows a different question if the answer is correct, if not it will stay on the same forumale. I would also like to add a skip button that will allow the user to skip the question if they cant figure it out.
So yeah my main issue is programming it ( i mean i can add buttons and program them to link to places (and show messages) but that is all lol) .
incase i didnt menmtion earlier, i am using Visual Basic 2005

i have two textboxes where a numeric value will get entered into both, these values will then be taken and the first value divided by the second value. The problem i am having is that if for example the first value is 11 and the second value is 10, when i divide 11 by 10 the result is 1. I have tried setting the output format to have 2 decimal places but it still displays 1 instead of 1.1. [Code]

I would like to develop an application that involves a lot of tables and maths, and then displaying the results. I can visualize how this would work in SQL, as far as creating the stored procedures and tables required, however the front facing application would be a completely new experience to me.I would probably be sharing the built application with friends, but completely as a no profit tool. I assume that the developer edition of dot net is a suitable option? My main query is, is dot net really the best way to develop this tool? I have a strong feeling that I will not be able to use SQL as this would require a server to be run, and this is not practical. Can the tables be implemented into a DLL or similar to be used by the application for example?

I have an ASP.NET web form which is used to send emails (Contact Us page). I use validation controls to validate the sender's name, email etc... everything works fine.However, I want to validate the body TextBox (on the server side) to implement the following: Only Letters and/or numbers. Nothing else; even fullstop and question mark should not be allowed. Letters can only be English and/or Arabic. That means no symbols; all the following characters are not allowed:
+ - _ * / > < = ~ ? . : , ; ' ! @ # $ % ( ) { } [ ] |

I have a web service I am working on. Recently I made a whole bunch of changes and now, although I can successfully compile it, when I run it my break-points will not work. The red dot turns into a circle and floating the mouse over it reveals the message:
The breakpoint will no currently be hit. No symbols have been loaded for this document.
I have NO idea what I changed to cause this to begin happening. One big change was to add a reference to a WSDL, but I really don't think that is the problem.[code]...

I had created a windows forms application in vb.net. It contained several windows. Now the users of that application are telling me to display all in one main form. They want to see all the details in one form. I had implemented MDI but they want something like tabs. On different tabs different forms should be displayed. How shall I implement this.

I'm using VS2010 and build a simple DLL project containing a simple class 'classSteve'. In this class I have one private int 'intSteve' and one method 'setSteveInt'.How do I compile this project so the 'classSteve', 'setSteveInt', and 'intSteve' are not strings stored in the resulting dll file?
In other words, how do I compile this project so the symbols are not stored in the dll?

As you can imagine this causes an error as the two " are not escaped. The issue is " doesn't work either. I imagine this is because Regex has special meanings for such symbols. So my question is should I use the ASCII codes for the the " and the other " ?
