Why Trust Us

Many developers code text boxes to only accept numeric values. They usually forget about keyboard and mouse copy and paste functions. The following code only allows values 1 to 9 in the text area and it doesn’t disable copy and paste commands.

 Dim strContentsBeforePaste As StringPrivate Sub Text1_KeyPress(KeyAscii As Integer)    Select Case KeyAscii        Case 3          'Copy - Ctrl+C        Case 8          'Backspace        Case 22         'Paste - Ctrl+V            strContentsBeforePaste = Text1.Text        Case 24         'Cut - Ctrl+X        Case 48 To 57   '0-9        Case Else            KeyAscii = 0    End SelectEnd SubPrivate Sub Text1_KeyUp(KeyCode As Integer, Shift As Integer)    'check if keyboard pasted data is numeric    If KeyCode = 86 Then  'paste - Ctrl+V        If Not IsNumeric(Text1.Text) Then            Text1.Text = strContentsBeforePaste            MsgBox
