Function long FindWindow (ref string lpClassName, ref string lpWindowName)Library "user32"
Function long GetWindowThreadProcessId (ref long hwnd,ref long lpdwProcessId)Library "user32"
FindWindow 返回符合指定的类名( ClassName )和窗口名( WindowTitle )的窗口句柄
我们把 FindWindow 函数中得到的句柄作为参数，来获得进程名柄lpdwProcessIDTop

你好！看见你关于进程方面的信息，但下面的用户对象及数据窗口对象
是如何定义的，请赐教！
nvo_process 及d_process
