HOMEWORK # 3

In this HW are will be adding extra GUI controls and functionality to HW # 2.

First, your calculator should be fully functional. This means that it should be able to

accomplish all arithmetic operations on any set of numbers. The number buttons should be

fully active and implemented. The user cannot edit the display what so ever and the cursor

should not be displayed (google how to do this OR use a Label instead of a TextBox)

If the input is 3 then + then 5 then = and then + then 4. Your calculator should display 12.

This means your calculator should be able to append other operations and operands on

results.

Next, your calculator should be able to convert between binary and decimal. You are only

required to do conversation and not binary arithmetic. In order to do this your will need to

add two radio buttons to your form that give the user the option to pick if he/ she want to

be in Decimal (default - startup) or binary mode.

This is an example of how your controls should / may look like

 

The binary mode is used solely to convert a number from Decimal to Binary and visaversa. Example: if the user enters the number 10 in decimal mode and then selects the

binary mode then 1010 should be displayed. If the user enters 101 while in binary mode

and then selects the decimal mode then the number 5 should be displayed. Make sure you

disable all non-necessary control elements when in binary mode. You need to write a

method for converting binary into decimal and another method to convert from decimal to

binary. (do not use built in method /API)

Hereis an example I found on the web to convert from decimal to binary

Finally. Your calculator should respond to keyboard key press (just like the calculator for

windows). So if someone presses the number 1 on the keyboard; this will mean that the

button with number 1 has been clicked and the display will show the number 1. If the * sign

is pressed on the keyboard; it should act as if the * button is clicked and if the enter button

is pressed on the keyboard then it acts just like if the “=” is clicked.

Hereis a link from MSDN that provides with the means on how to do this. Read it carefully.

I have attached my fully working calculator except with the add ons I need. I am having trouble doing this. I am new to C# and programming so I need help! THanks
