Need help with Code for a Calculator?

[Chris25]

Hi everyone! I need a little help with a calculator i am developing. Heres the layout...... 3 text boxes(each one labeled firstnumber,secondnumber, and product). Also i have 4 option buttons(add,subract,multiply, and divide) and i have one command button that calculates the totals from the first two text boxes. Now how do i write the code for the option buttons so that when i click each one of them they will add , sub, multiply and divide. When i try to write the code different ways i keep getting compile error. Also do i put most of the code in the command button, so when i click it the input in the first two text boxes either adds them, subtracts them, multiplys or divides?? Thanks for any help you can give me.

put the code in the command button click event. there you look to see what option button is checked and perform associated operation.

Something like this maybe?


private Sub Command1_Click()
Select Case true
Case optAdd
Text3.Text = Val(Text1.Text) + Val(Text2.Text)
Case optSub
Text3.Text = Val(Text1.Text) - Val(Text2.Text)
Case optMul
Text3.Text = Val(Text1.Text) * Val(Text2.Text)
Case optDiv
Text3.Text = Val(Text1.Text) / Val(Text2.Text)
End Select
End Sub



Note to merrion: I used your if-then-elseif-to-select-case method you posted on http://www.vbcodelibrary.co.uk/board, and I like it!
