wince中hook的问题

wince中hook的问题 [复制链接]

看了很多资料wince下只支持三种hook.
按照资料加载coredll.dll,在模拟器上调试.使用WH_KEYBOARD_LL安装后返回的hook是0x01.而且不进处理程序,使用WH_JOURNALRECORD,安装后返回的是0.
请问是模拟器的问题吗?
代码几乎是和网上的一样

键盘的HOOK，LZ是如何实现与加载的？

和模拟器的关系不大。

试试这个，我使用使用WH_KEYBOARD_LL已经可以正常使用了

1. BOOL ActivateKBHook(HINSTANCE hInstance)//, HOOKPROC LLKeyboardHookCallbackFunction)

我使用的是全局hook，写了个dll

xl7926

HINSTANCE hInstance怎么赋值呢?
我也是写的dll,全局Hook.我把hInstance赋值为theApp.m_hInstance.因为wince的winmain第一个参数是handle

cailingli521

LLKeyboardHookCallbackFunction这个函数需要定义为dllexport吗?

qqwo

WH_JOURNALRECORD在wince下能实现吗?

我是这样调用钩子的，其中，AdKeyboardHook是dll文件的名字。
ActivateKBHook(GetModuleHandle(_T("AdKeyboardHook")));///////调用dll，挂钩

不用的。
我只 __declspec(dllexport) BOOL ActivateKBHook(HINSTANCE hInstance);
还有一个
__declspec(dllexport) BOOL DeactivateKBHook();

这个没试过

按照你的一样写了，还是得到hook是0x01

nebulabhm

SetWindowsHookEx        = NULL;
CallNextHookEx            = NULL;
UnhookWindowsHookEx        = NULL;
g_hHookApiDLL = LoadLibrary(_T("coredll.dll"));

SetWindowsHookEx = (_SetWindowsHookExW)GetProcAddress(g_hHookApiDLL, _T("SetWindowsHookExW"));
      
CallNextHookEx = (_CallNextHookEx)GetProcAddress(g_hHookApiDLL, _T("CallNextHookEx"));
           
UnhookWindowsHookEx = (_UnhookWindowsHookEx)GetProcAddress(g_hHookApiDLL, _T("UnhookWindowsHookEx"));
           
函数的值都能得到。
glhHook = SetWindowsHookEx(WH_KEYBOARD_LL, (int)MouseProc, gInstance, 0);

没有人遇到过吗？
安装hook得到0x01

得到的值是多少我不清楚，不过我的可以提示("set hook 成功"),
