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.

I want to make a game statistics calculator. For this I choose to make a XML database with the base stats of the characters.
I've made a small XML file in the VS2010 project with 1 class stats and made a list to 10 levels (to lazy atm to write all 85).
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

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 trying to make a calculator that adds from two text boxes and displays the answer in another box, but It gives an error when someone enters a character. What can I do to display a string error message in the third box if a letter is entered in one of the first two boxes instead of a number?

I can't get the loop to work. The calculator is suppose to show how far someone goes for each hour increment (i.e. if they punch in 3 hours, it should show a number for 1 hour, 2 hours and 3 hours; if they punch in 10 hours it should show a number for 1 hour, 2 hours, 3 hours....etc. up to ten hours, etc.) I can't get it to show anything except for the total number of hours traveled and total distance.
Private Sub DistanceButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles DistanceButton.Click

This is one of my first forms so I'm sure there is quite a bit wrong with it. It works to a good degree but my issue is, Although I'm asking and checking for an int. If I put say 1.1 in a field it still lets it go. I'm sure I'm missing something very easy but I've been messing with it for hours.

I'm looking for a definitive, standard (i.e. certified as being correct or tested reasonably thoroughly) for calculating the ISO week from a date, in Visual Basic (i.e. to run in a Visual Studio Express 2010 Visual Basic project).

I have written the below code for a payroll calculator. When I run the program, it gives me my own error message box no matter if my number of hours fall within the 5-60 hours range as I have stipulated. Is there something wrong with my code?

Sweet candy store currently has a special offering of heart shaped candy. It comes in two sizes: small and large. The company sells the large one for $29.50 and the small for $16.25.Design an application to calculate how much a costumer owes. When the user clicks the "Calculate" button, the program gets the number of large and small chocolate hearts ordered from the textboxes, calculates and displays the extended price for each type of the chocolate in a label. The program also calculates the weight of the chocolate to determine the shipping cost, displays the total weight, the shipping cost and the final total due. The large chocolate weighs 4 pounds 10 ounces, and the small one weighs 2 pounds 14 ounces. Shipping cost is 35 cents per pound and 3 cents for each additional ounce. Display all dollar amounts except the final total due with 2 decimal places. Display the FINAL TOTAL DUE with a leading dollar sign and 2 decimal places. Be sure to also include a CLEAR button that will remove all inputs/outputs from the form, and an EXIT button. Define the CALCULATE button as the accept button and the EXIT button as the cancel button.
