问题
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?
回答1:
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.
