用一个叫vb2c#转的，我也不知道对不对，供参考
另外一个例子参考
今晚因为某种用途用到RegisterShellHookWindow
，使用还是比较简单的，功能也不错，详细看下MSDN。把代码贴出来
HWND Hwnd =
GetSafeHwnd();
msgShellHook =
RegisterWindowMessage("SHELLHOOK");
RegisterShellHookWindow(
Hwnd );
lpPrevWndProc = SetWindowLong( Hwnd
, GWL_WNDPROC, (LONG)WindowProcxx );
/////////////////////////////////////////////////////////////////////////////////
LRESULT
CALLBACK WindowProcxx(
HWND hwnd,
UINT uMsg,
WPARAM
wParam,
LPARAM lParam
)
{
CHAR szProcessPath[_MAX_PATH] = { 0 };
DWORD dwPid =
0;
#define HSHELL_APPCOMMAND 12
if( uMsg == msgShellHook)
{
switch(
wParam )
{
case
HSHELL_WINDOWCREATED:
{
GetWindowThreadProcessId(
(HWND)lParam ,&dwPid);
if( dwPid !=
GetCurrentProcessId())
{
GetProcessName(
dwPid , szProcessPath, _MAX_PATH
);
MessageBoxA(NULL,"窗口创建",
szProcessPath, MB_OK);
}
}
break;
case
HSHELL_APPCOMMAND:
{
MessageBoxA(NULL,"xx窗口创建",
szProcessPath,
MB_OK);
}
case
HSHELL_REDRAW:
//比如TAB也却换
{
MessageBoxA(NULL,"窗口HSHELL_REDRAW",
szProcessPath,
MB_OK);
}
break;
default:
break;
}
}
return CallWindowProc((WNDPROC)lpPrevWndProc, hwnd, uMsg, wParam, lParam);
}
后注：
RegisterShellHookWindow
就是
NtUserCallHwnd 传入 72号。 这个数其实是个索引。用于索引_apfnSimpleCall
而 _apfnSimpleCall
是一个保存着许多函数指针的一个数据结构。我们可以通过下列的函数来调用_apfnSimpleCall里面的函数。因为这些函数的参数比较少，没有参数，一个参数或者俩个参数，所以下面的函数名号理解。
NtUserCallHwndParam
NtUserCallNoParam NtUserCallOneParam
NtUserCallTwoParam等
每个接受的INDEX是有限制的。
一些安全软件可能会HOOK
NtUserCallOneParam NtUserCallTwoParam之类的。具体看
_apfnSimpleCall里面的指针，看你对哪个感兴趣就HOOK哪个。
或者直接修改 _apfnSimpleCall
里面的指针来达到目的也可以。这样比较隐蔽。
嗯，就看这些，有时间再看下，复习去。
