Question

如何在动态链接库中使用全局钩子函数，当鼠标移动时来修改来和隐藏别的窗口－－例子代码

Answer 1

#pragma data_seg("mydata")
HWND glPreTarWnd = NULL;
HWND glTargetWnd = NULL;
HWND glSelfWnd = NULL;
#pragma data_seg() //定义
LRESULT WINAPI MouseMoveProc(int code,WPARAM wParam,LPARAM lParam)
{
if(code < 0)
return CallNextHookEx(glMouseHook,code,wParam,lParam);  LPMOUSEHOOKSTRUCT pMouseHookWnd=(MOUSEHOOKSTRUCT FAR *)lParam;
glTargetWnd = pMouseHookWnd->hwnd;//获取相应的窗口的句柄 char szWinCaption[]=_T("一切可以修改的句柄标题已多经过修改...");
::EnableWindow(glTargetWnd,szWinCaption);//标题修改
          ::EnableWindow(glTargetWnd,FALSE);//隐藏窗口        return CallNextHookEx(glMouseHook,code,wParam,lParam);
}extern "C" _declspec(dllexport) BOOL WINAPI ExternMouseMoveToWinText(HWND hWndDes)
{
if(hWndDes == NULL)
return FALSE;
glSelfWnd = hWndDes;
glPreTarWnd = hWndDes;
glMouseHook = SetWindowsHookEx(WH_MOUSE,MouseMoveProc,glMouseInstance,0);
return TRUE;
}extern "C" _declspec(dllexport) void WINAPI StopHook()
{
UnhookWindowsHookEx(glMouseHook);
glMouseHook = NULL;
}

//连上的全局定义 glMouseInstance 是用DllMain传入的参数
#pragma data_seg("shareddata")
int nNum=0;
HHOOK glMouseHook = NULL;
HINSTANCE glMouseInstance = NULL;
#pragma data_seg()
