I’ve got a Winforms application that I am in the process of translating into Chinese. I’ve got a numeric text box that validates the input with a regular expression. When the user is entering text with IME, numeric digits don’t seem to come in as numeric digits.

On possible work around I have found is to set the ImeMode property of the text box to ‘Off’. In my testing, this makes everything correctly, but I don’t have a ton of experiance with IMEs.

What are the negative impacts of setting the ImeMode to Off? Is this something I should avoid at all costs or is it ok if the only things the user can enter are numbers?

    According to the MSDN documentation, it is OK to turn off the IME for a numeric field.

    An IME is a program that enables users
    to enter complex characters and
    symbols, such as Japanese Kanji
    characters, using a standard keyboard.
    The ImeMode property is typically set
    to ImeMode.Off for a TextBox control
    that is intended to only enter numeric
    values.
