Make A Calculator With One Textbox And 16 Buttons?
May 8, 2012
I am trying to make a calculator with one textbox and 16 buttons. Buttons are:(0,1,2,3,4,5,6,7,8,9,+,-,*,/,=,C). So here is code for now:
vb.net Private Sub nula_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles nula.Click
TextBox1.Text = TextBox1.Text & 0
End Sub
Private Sub jedan_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles jedan.Click
TextBox1.Text = TextBox1.Text & 1
[Code]...
When I add those numbers and operators its easy, but how make operations really work now?

how to make a zodiac calculator, I know the basic codes that I need to insert, but I'm creating it in a windows application. The day and year are text boxes that the user can input that particular information, but the month is a drop-down box. My two questions are: Is it okay to delete the private sub of the day and year so I can combine them into one sub? And how do I get the months to show up individually in the code area? Or would I have to delete the drop-down box completely and make it like the day and year text boxes where the user can input the information themselves?

I mean not like windows xp which the number and signs are not in the same textbox, but like windows 7 which you can see the whole calculation before pressing equal, and i don't think that compute.datatable can do this because it's limited with the basic signs(+,-,/,*) and it doesn't include the other signs(like : sin,^,root,log), so how to make a calculator like windows 7 one?

I am trying to make a simple resistance calculator for practice. I use text boxes to let the user input the current and voltage, and then a combo box for the units and then a list box to display the results. For some reason no matter which units I select it doesn't convert at all. For example 1/2 will always show up as 0.5 in the list box no matter which units are selected from the combo box. Here is my code.....I know that there is more cases but I only put one to see if it works before I write all of the cases.
Public Class Form1
Dim unitsA As String
Dim unitsV As String

I'm new in the programming area and I'm having trouble making a calculator. My question is: How do I make the calculator work using only the keyboard, without the need of mouse.
I tried this:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs)
Me.KeyPreview = True
End Sub
Private Sub FlowLayoutPanel1_KeyDown(ByVal sender As Object, ByVal e
As System.Windows.Forms.KeyEventArgs) Handles RESULTADO.KeyDown
If e.KeyCode = Keys.NumPad0 Then
[Code] .....
It only works on the text box called Result. I want to know how do I make work in the whole Class, and if it is possible, to make it work on two different Classes without writing twice the same code.

the XML looks like this:
<BASIC_CHARACTER_STATS>
<Levels>
<level id="1">1</level>
[Code]....
On the Form1.vb I've to combo boxes, 1 to display class names and 1 for levels.
Also have some Labels to display i.e. the base_STR number. But after trying random stuff to get it linked and closed VB to restart again because it was messed up too much

I am building a scientific calculator.
1. After I clicked the Sine button, I get the result in a textbox.. When the result is there, for example: 1 radians Sine = 0.8414.... I can still put numbers at the end of this result.. like button 5 will be 0.84145, so how can I disable that?
2. After I get the result from a calculation, the textbox should be cleared when I insert a new number.

I am trying to develop a simple math calculator that will allow the user to input the right-hand-side (RHS) of an equation into a textbox on the application and have the application evaluate the expression for a given value of x, which is also input
into the application by the user via another textbox.For example, if the user wants to evaluate the following expression,
y = 3 + 4*x + 5*x^2
then they would input into the textbox the RHS of the equation
3 + 4*x + 5*x^2
and then enter a value of x into the another textbox and click on the calculate button.I tried this:
answer = EquationTextBox.Text
but it doesn't work.

I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?
