一点猥琐代码
-
// Register app for pen windows (if possible) bPenWin = FALSE; if ((hPenWin = GetSystemMetrics (SM_PENWINDOWS)) != NULL) { if ((RegisterPenApp = (LPREGISTERPENAPP) GetProcAddress (hPenWin, " RegisterPenApp " )) != NULL) { ( * RegisterPenApp)(RPA_DEFAULT, TRUE); bPenWin = TRUE; } }
SetWinEventHook这个函数可以用来注入DLL..
具体如何注入看MSDN吧..还有其他很多猥琐的用法```具体如何猥琐大家自己想吧。
我刚开始用这个函数的时候始终能安装成功，但是就是无法捕获到信息..
最后到国外...再查阅MSDN发现有这么一句话..
The client thread that calls SetWinEventHook must have a message loop in order to receive events.
翻译一下就是：调用了SetWinEventHook h函数的线程需要一个消息循环来接受事件。
之前一直写个MAIN就完了..杯具啊！！
代码如下：
#include
#include
#include
#include
#include "resource.h"
#pragma comment(lib, "Oleacc.lib")
// Global variable.
HWINEVENTHOOK g_hook;
// Callback function that handles events.
//
void _stdcall HandleWinEvent(HWINEVENTHOOK hook, DWORD event, HWND hwnd,
LONG idObject, LONG idChild,
DWORD dwEventThread, DWORD dwmsEventTime)
{
IAccessible* pAcc = NULL;
VARIANT varChild;
HRESULT hr = AccessibleObjectFromEvent(hwnd, idObject, idChild, &pAcc, &varChild);
if ((hr == S_OK) && (pAcc != NULL))
{
BSTR bstrName;
pAcc->lpVtbl->get_accName(pAcc, varChild, &bstrName);
if (event == EVENT_SYSTEM_MENUSTART)
{
printf("Begin: ");
}
else if (event == EVENT_SYSTEM_MENUEND)
{
printf("End: ");
}
printf("%S\n", bstrName);
SysFreeString(bstrName);
pAcc->lpVtbl->Release(pAcc);
}
}
// Initializes COM and sets up the event hook.
//
void InitializeMSAA()
{
CoInitialize(NULL);
g_hook = SetWinEventHook(
EVENT_MIN, EVENT_MAX, // Range of events (4 to 5).
NULL, // Handle to DLL.
HandleWinEvent, // The callback.
0, 0, // Process and thread IDs of interest (0 = all)
WINEVENT_OUTOFCONTEXT); // Flags.
}
// Unhooks the event and shuts down COM.
//
void ShutdownMSAA()
{
UnhookWinEvent(g_hook);
CoUninitialize();
}
INT_PTR CALLBACK DialogProc(
__in HWND hwndDlg,
__in UINT uMsg,
__in WPARAM wParam,
__in LPARAM lParam
)
{
switch(uMsg)
{
case WM_CLOSE:
EndDialog(hwndDlg, 0);
break;
default:
return FALSE;
}
return TRUE;
}
int main(int _argc, char **_argv, char **_evn)
{

hInstance = GetModuleHandle(NULL);
InitializeMSAA();

return 0;
