qustion in calculator

Private Sub Button1_Click()
    txtWindow.Text = Trim(txtWindow.Text) + 1
End Sub

Private Sub Button2_Click()
    txtWindow.Text = Trim(txtWindow.Text) + 2
End Sub

Private Sub Button3_Click()
    txtWindow.Text = Trim(txtWindow.Text) + 3
End Sub

You should probably use a label instead of the textbox, so the user could not type in  a number.

Create a new project a add a textbox to serve as the number display.  Add just ONE commandbutton to the project.  Now select the commandbutton and copy and paste it so you have eleven buttons, all part of a control array (say yes to the question).  Arrange the buttons in 3 x 4 grid  with the middle button of the last row missing.  Now change the captions of the buttons so you have eleven buttons with "1", "2", "3", "4", "5", "6", "7", "8", "9", "0" and "." on them (without the quotes of course).  Run the project and hit the buttons. =)

Private Sub Command1_Click(Index As Integer)
    If Command1(Index).Caption = "." Then
        If InStr(Text1.Text, ".") = 0 Then ' Allow only one decimal in number
            Text1.Text = Text1.Text & Command1(Index).Caption
        End If
    Else
        Text1.Text = Text1.Text & Command1(Index).Caption
    End If
End Sub

Private Sub Form_Load()
    Text1.Alignment = vbRightJustify
    Text1.Text = ""
End Sub

If you decide to do it the way Idle_Mind suggested remember to assign 0 Index to your "0" button, 1 Index to "1" and so on.

Actually, the indexing doesn't matter.  The code pulls the caption from the current button that was pushed using the index parameter passed to the Command1_Click(Index As Integer) sub.  Some consider this is a bad programming practice but the it keeps the code repetition down and the code was simply to demonstrate how to append text to a textbox. =)

try this one:
Add a 10 button on your form and do the code below.

Code for the 1st button...

Private Sub cmdButton1_Click()
Text1.text = mid(Text1.text,1,1)
End sub

Code for the second Button...

Private  Sub cmdButton2_Click()
Text1.Text = mid(Text1.text,2,1)
End Sub

this is for the 3rd button...

Private Sub cmdButton3_Click()
Text1.text = mid(Text1.text,3,1)
End sub

Do this until you reach the 9th button....

and this is for the 0 button...

Priavate sub cmdButton0
text1.text = ""
End Sub

Just use

Private Sub cmdButtonname_click()
txtTextbox.Text = txtTextbox + "NUMBER ON BUTTON"
End sub

Private Sub Command1_Click()
text1.text=text1.text&"3"
End Sub

// I dont have vb at present so I havent tested this

Using the + is better than & in the above example

using + with the text being "hello " and the number on the button being 3 would give you "hello 3" whereas using the & sign could give you that or "hello _3" with an underscore underneath the 3, sorry its a continental keyboard (yes i am doing this on my holiday!)


bye now

What did you end up doing with your calculator?

lol

Don't post any more comments here and it will get cleaned up automatically
