HowcanImakethe"Copy" button copy all text from the textbox?
So I understand it's to copy to clipboard, so it's like this in VB:
Clipboard.SetText(Text1.Text)
where Text1.text is your text
Private Sub Command1_Click ()
txt.SelStart = 0
txt.SelLength = Len (txt.Text)
txt.SetFocus
Clipboard.Clear
Clipboard.SetText Screen.ActiveControl.SelText
End Sub
