Yes, You understanded me.

I am using a chinese input method from google in winxp.
When I input in any program, the input method will first receive my
input.
If that input stat is english , my program will get the english
charater.
If that input stat is chinese, google's input method will give me a
list to select,and then my
program will get the chinese chararter.
To switch between the english and chinese is to use only "Ctrl" key
once.

Thanks anyway!!!
