Hi Guys

I have found a way to handle individual key press on textboxes but this way I have to code each textbox on its own.
I would like to know how to set a rule / Key Press event for all textboxes on the form.
So when the Key: “ ‘ “ is pressed do nothing.
Im getting errors when saving data using the character “ ‘ “
I hope this makes sense... : )

Ami I got it to work:

set the KeyPreview property of the form to true

My Code..

VB

Sub Form1_KeyPress(ByVal sender As Object, _
    ByVal e As KeyPressEventArgs) Handles Me.KeyPress

    If e.KeyChar = ChrW(39) Then
        MessageBox.Show(("Form.KeyPress: '" + _
            e.KeyChar.ToString() + "' pressed."))

        Select Case e.KeyChar
            Case ChrW(39)
                MessageBox.Show(("Form.KeyPress: '" + _
                    e.KeyChar.ToString() + "' consumed."))
                e.Handled = True
        End Select
    End If
End Sub

End If
End Sub

End If
End Sub

Thank you so much for the help

Cheers

You can handle a Form event KeyPress[^] at the Form Level.

VB

Sub Form1_KeyPress(ByVal sender As Object, _
    ByVal e As KeyPressEventArgs) Handles Me.KeyPress

    If e.KeyChar >= ChrW(48) And e.KeyChar <= ChrW(57) Then
        MessageBox.Show(("Form.KeyPress: '" + _
            e.KeyChar.ToString() + "' pressed."))

        Select Case e.KeyChar
            Case ChrW(49), ChrW(52), ChrW(55)
                MessageBox.Show(("Form.KeyPress: '" + _
                    e.KeyChar.ToString() + "' consumed."))
                e.Handled = True 
        End Select 
    End If 
End Sub

This answer is just a reference of How to: Handle Keyboard Input at the Form Level[^]

Hope it helps.!
