Preventing user from changing input methods??

[Guest psneddon]

Hi,

I am aware how to change the input mode using code (e.g. text, numbers, t9), but how do I prevent the user from changing it when it is on a certain control, for example if my text imput box only accepts numbers how to I prevent the user from holding the * key and changing the imput mode to something else. Do I need to intercept the pressing of the * key??

Regards,
