but that gave me NO characters for input. Do I have to put all 128 ASCII characters in AcceptedCharacters (I am assuming there is no way to access the high bit chars.)?
As the code above shows, I was setting a custom filter using IME. I was assuming I needed to use IME to remove the filter. Are you telling me that I can remove the filter just by setting ValueTxt.InputType = ValueTxt.INPUT_TYPE_TEXT?
