I did something like this myself. Use two variables (ie: Dim dblVal1 As Double, dblVal2 As Double).
Pass the 1st test entry to dblVal1, clear the text box (when the user presses a function key such as '+'), then pass the 2nd text box entry to dblVal2.
just use cache to perform this type of operation...
It will b fine.
Adding to Numbers using your Numeric keypad VB.NET 2003
Just drag 1 label to your form
label1.backcolor = color.black
label1.forecolor = color.green
make some adjustments to your font as you want
Declare your variables
in your form use the KeyUp event
and place the code below
Private f as String 'your first number Private s as String 'your second number private n as String private o as String 'this will be your operators variable Private sum as Double Private Sub MainForm_KeyUp(Byval sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyUp Select case e.KeyCode Case keys.Numpad0, keys.NumPad1 '(provide all the keycodes) f = e.KeyCode.ToString 'this will display what key your pressed f = f.Substring(6, 1) 'we will extract the last string of the keycode string n = n & f 'we will pass our first number to our variable n me.label1.Text = n 'we will display whats on variable n Case keys.Decimal 'hmmm we will make some flavoring here n = n & "." f = "" n = n & f Case keys.Add o = "+" 'assign a plus sign to operators variable s = n 'we will pass our first number to the second number sum= Val(s) + Val(r) ' me.label1.Text = FormatNumber(sum, 2, TriState.True, TriState.True, TriState.True) n = "" r = sum Case keys.Subtract 'do your part, explore, and discover something extraordinary 'happy coding End Select
so if i hopes there's nothing missing on the codes
