Hi,

How do I use:
Dim Text As String * 6

I want to use EditText with fixed number of characters. Is this possible or do I have to make a check myself?

Best regards,
André

there is no property to set maximum characters in EditText .. you will have to manage input yourself.
B4X: 
Sub EditText1_TextChanged (Old As String, New As String)
  If New > 6 Then EditText1.Text = Old
End Sub

I think this line:
B4X: 
If New > 6 Then EditText1.Text = Old
shoud be:
B4X: 
If New.Length > 6 Then EditText1.Text = Old

Thanks for all help. It works fine now.

But:
B4X: 
If New.Length > 6 Then EditText1.Text = New.Substring(0, 6)

Had to be
B4X: 
If New.Length > 6 Then EditText1.Text = New.Substring2(0, 6)

I did not dream I would have to audit it for errors !!
