关于定义变量的问题。

[programfish]

Private Declare Function ReadProcessMemory Lib "kernel32" (ByVal hProcess As Long, lpBaseAddress As Any, lpBuffer As Any, ByVal nSize As Long, lpNumberOfBytesWritten As Long) As Long

Dim r&

r = ReadProcessMemory(hProcess, &H1011F20, retV, 2, 0)

运行时说hProcess没有定义，在声明API时已经定义了啊，请问怎么回事，怎么解决？

hProcess是窗体的HWND.你调用时可用以ME.HWND代替.

[skywolfY]

pProcess是函数的形参，真正在使用时，要用实参来代替
下边的r=..后边的hProcess是没有定义
但这里的hProcess不是上边byVal hProcess
