In my program, I want to set some net configuration through a dialog, and I create a IP control in it with classwizad. but when I set the ip control's value or get it, there is always an error. I guess it is caused by that I don't initialize the control. then i use the create() function to initialize it, but it is still error. Why? how should i do.

I just use these codes to get it, but the QueryInterface always failed. Then I try to get the interface to the CaptureBuffer, it is ok. Why these happened? laia

use AfxSocketInit() to intilize the socket before use socket's function. and there are some samples in the MFC, such as chatter, it would be good to you. best regard. laia

I build a dialog application using VC++, and I want to deal with the keyboard message. but the ON_KeyDown fuction can't work, it can't be called by framework at all. then I find that I can deal with keyboard message in the PreTranslateMessage function, but it just like odd. I think it must have a better method. thanks laia
