VB知道窗口句柄怎么得到进程句柄?

Answer 1

你是说进程Pid吗？
上面的hProcess最好用hWnd，是窗口句柄
用API：
新建模块，输入
Option Explicit
Private Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hWnd As Long, lpdwProcessId As Long) As Long
'自建函数
Public Function GetPidFromHWnd(ByVal hWnd As Long)As Long'返回值就是Pid
On Error Resume Next
Dim tPid As Long
Call GetWindowThreadProcessId(hWnd,tPid)
GetPidFromHWnd=tPid
End Function

模块Okay
调用就好了
PID（进程编号）=GetPidFromHWnd(hWnd)'这里的hWnd就是你上面的hProcess
