Calculator

In order to add in a calculator you need to first enter the first number then click "+" and enter the second number. My problem is that when the user clicks "+" the text box will be set to "". So how can I add the second number

Store the first number in a variable, then store the second number in another variable... then add them and display in the textbox :thumb:

VB Code:

Private Function Example()
Dim FirstNum, SecondNum As Integer
FirstNum = "0"
SecondNum = "0"
FirstNum = Text1
' do whatever to textbox and then add other number
SecondNum = Text1
Msgbox FirstNum + SecondNum
end function

something like that should do fine...didn't try it in VB yet, so good luck ;)

Have a look at the calculator that comes with VB6. :thumb:
