Did you bother reading the replies before posting?

Instead of using int (integer) I have started to use val (value) as it automatically creates memory for complex numbers in case a decimal or other extended math is used.

I know that in the old days, conserving memory was important and many programmers still code that way and YES it is still important but when speed is not an issue in small programs, In my opinion, val is a good cover all, just in case.

Look through these sites for your homework needs, you still have to do the research, don't forget to take a Research class when you get to college.

Don't copy, do your own work, tailor it to something simple when you locate a good sample.

Option Explicit
Dim first As String
Dim second As String
Dim operation As String
Dim output As Double

Private Sub Command1_Click(Index As Integer)
Text1.Text = Text1.Text + Command1(Index).Caption

TRY THIS ONE!!

Thanks 4 help! :))

MAKE A PROJECT OF CALCULATOR IN
VISUAL BASIC
First we select the Standard exe item in the view
project dialog box,
opening Visual
Basic itself.
Then we select the Textbox from the Toolbox and make
a textbox on the form.
Then we select the command button from the tool box
from the tool box we make buttons 0, 1, 2, 3, 4 … 9, +,
=,-,*, /, clear.
After these all buttons are made. Then we need the
buttons to be coded. Thus double click on the button
numbered “1”, following coding is done:
Private sub Command 1-Click ()
Text1.Text = Text 1. Text + “1”
End Sub
Double clicking on the Button “2”
Private sub Command 2-Click ()
Text1.Text = Text 1. Text + “2”
End Sub
Double clicking on the Button “3”
Private sub Command 3-Click ()
Text1.Text = Text 1. Text + “3”
End Sub
Double clicking on the Button “4”
Private sub Command 4-Click ()
Text1.Text = Text 1. Text + “4”
End Sub
Double clicking on the Button “5”
Private sub Command 5-Click ()

Text1.Text = Text 1. Text + “5”
End Sub
Double clicking on the Button “6”
Private sub Command 6-Click ()
Text1.Text = Text 1. Text + “6”
End Sub
Double clicking on the Button “7”
Private sub Command 7-Click ()
Text1.Text = Text 1. Text + “7”
End Sub
Double clicking on the Button “8”
Private sub Command 8-Click ()
Text1.Text = Text 1. Text + “8”
End Sub
Double clicking on the Button “9”
Private sub Command 9-Click ()
Text1.Text = Text 1. Text + “9”
End Sub
Double clicking on the Button “0”
Private sub Command 10-Click ()
Text1.Text = Text 1. Text + “0”
End Sub
Double clicking on the Button “.”
Private sub Command 11-Click ()
Text1.Text = Text 1. Text + “.”
End Sub
Double clicking on the Button “+”
Private sub Command 12-Click ()
a= Text 1. Text
Text1.Text = ”+”
d=1
End Sub
Double clicking on the Button “-”
Private sub Command 13-Click ()
a= Text 1. Text
Text1.Text =”-”
d=3
End Sub
Double clicking on the Button “*”
Private sub Command 14-Click ()
a= Text 1. Text
Text1.Text =”*”
d=3
End Sub
Double clicking on the Button “/”
Private sub Command 15-Click ()
a= Text 1. Text
Text1.Text =”/”
d=4
End Sub
Double clicking on the Button “Square”
Private sub Command 16-Click ()
a= Text 1. Text
Text1.Text =”*”
C=a*a
Text1.Text = c
End Sub
Double clicking on the Button “Factorial”
Private sub Command 17-Click ()
a= Text 1. Text
Text1.Text =”i”
e= 1
for I = s to step-1
e = e*i
Text1.Text = e
End Sub
Double clicking on the Button “Clear”
Private sub Command 18-Click ()
Text1.Text ( )
End Sub
Double clicking on the Button “=”
Private sub Command 19-Click ()
b = Text1.Text
Select case d%
Case 1: c= a + b
Text1.Text = c
Case 2: c = a - b
Text1.Text=c
Case 3: c= a * b
Text1.Text = c
Case 4: c= a / b
Text1.Text = c
End Select
End Sub
Following figure shows how a
calculator made in Visual Basic
Looks :

Code for Number button from 0-9:

Private Sub command1_Click()
Text1.Text = Text1.Text & "1"
End Sub

Private Sub Command10_Click()
Text1.Text = Text1.Text & "0"
End Sub

Private Sub Command2_Click()
Text1.Text = Text1.Text & "2"
End Sub

Private Sub Command3_Click()
Text1.Text = Text1.Text & "3"
End Sub

Private Sub Command4_Click()
Text1.Text = Text1.Text & "4"
End Sub

Private Sub Command5_Click()
Text1.Text = Text1.Text & "5"
End Sub

Private Sub Command6_Click()
Text1.Text = Text1.Text & "6"
End Sub

Private Sub Command7_Click()
Text1.Text = Text1.Text & "7"
End Sub

Private Sub Command8_Click()
Text1.Text = Text1.Text & "8"
End Sub

Private Sub Command9_Click()
Text1.Text = Text1.Text & "9"
End Sub

Code For addition,subtraction.division and Multiplication:

Private Sub Command13_Click()
Label1.Caption = Val(Text1.Text) * Val(Text2.Text)
End Sub

Private Sub Command14_Click()
Label1.Caption = Val(Text1.Text) / Val(Text2.Text)
End Sub

Private Sub Command11_Click()
Label1.Caption = Val(Text1.Text) + Val(Text2.Text)
End Sub

Private Sub Command12_Click()
Label1.Caption = Val(Text1.Text) - Val(Text2.Text)
End Sub

Exit code for Clear:

Private Sub Command16_Click()
Label1.Caption = ""
Text1.Text = ""
Text2.Text = ""
End Sub

Exit Code:

Private Sub Command17_Click()
Unload Me
End Sub
