I know that this isn't new. a lot of post like this already

but here, this includes MEMORY FUNCTION IN CALCULATOR, square root, percent,
receprocal, square of a number and cube of a number.

this also includes a SOUND produced in every click made in buttons,
Formulas, Theme used for the form( from gambino) and a round buttons.

For details, please have a look on the project file(download link provided)

IMPORTANT:
alt 251 = for squareroot
alt 241 =for plusminus sign

MR =means ' recall memory and desplay in textbox
MC =means' delete the number in memory
MS =means ' store the current number from textbox to the memory
M+ = means add the current number from textbox to the number in memory
M- =means' deduct the current number from textbox to the number in memory

this is a freaking cool , very nice tut well explained and the GUI is superb by the way 0 the borders of buttons to make it look more good

[noypikami]

@ mshimranpro... yes the border should be zero and the style is flat

check the code below.... it change the flat style to pop -up in buttons when mouse hover into it
this code handles multiple buttons

Code: Select all

 'HANDLES MOUSE EVENTS WHEN MOUSE MOVES OVER A BUTTON
    Private Sub but_MouseEnter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.MouseEnter, Button2.MouseEnter, Button3.MouseEnter, Button4.MouseEnter

  CType(sender, Button).FlatStyle = FlatStyle.Popup
      
    End Sub

    Private Sub but_MouseLeave(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.MouseLeave, Button2.MouseLeave, Button4.MouseLeave, Button3.MouseLeave
    
      CType(sender, Button).FlatStyle = FlatStyle.Flat
        CType(sender, Button).FlatAppearance.BorderSize = 0
    End Sub
