Background: I want to be a child window dialog box, but since the goal is to do an interface library, so can't use to. Throw in rc dialog. Create a dialog when need initial control, if I use # 32770 when creating the window dialog box, does not handle WM_CREATE message handler, cannot create response and
So, I want to create your own window class should be response WM_CREATE message handler ( I don't know but I want to try, if you have better way can also

Don't use the method of adding the Dialog resource file thank you
this is all the code, the goal is to solve the problem of class to create and implement in the child window to create the corresponding response.
