在没有DLL的情况下全局使用WH_MOUSE [英] Use WH_MOUSE globally without DLL

问题描述

我有一个代码，可以在鼠标移动时显示部分屏幕.但是WH_MOUSE不起作用.我需要将 GetModuleHandle(0)，0 更改为 hInst，GetCurrentThreadId().

I have a code to display a part of screen when mouse moves. But the WH_MOUSE doesn't work. I need to change GetModuleHandle(0), 0 to hInst, GetCurrentThreadId().

但是只有当鼠标悬停在应用程序本身上时，该应用程序才能工作.

But then the application will work only when the mouse is over the application itself.

我希望它是全局的，我尝试了WH_MOUSE_LL，它比WH_MOUSE慢.

I want it global and I tried WH_MOUSE_LL, it is slower then WH_MOUSE.

是否可以在没有DLL的情况下全局使用WH_MOUSE?

Is that possible to use WH_MOUSE globally without DLL?

void SetHook()
{
    gMouseHook = SetWindowsHookEx(WH_MOUSE, MouseProc, GetModuleHandle(0), 0);
}   

//================================================================================
// Mouse Hook

static LRESULT CALLBACK MouseProc(int nCode, WPARAM wParam, LPARAM lParam)
{
    if (nCode < 0) {
    return CallNextHookEx(gMouseHook, nCode, wParam, lParam);
    }

    if (wParam == WM_MOUSEMOVE) {

    MOUSEHOOKSTRUCT *mouseInfo = (MOUSEHOOKSTRUCT*)lParam;

    int x = mouseInfo->pt.x;
    int y = mouseInfo->pt.y;

    PrintScreen(x, y);
    }

    return CallNextHookEx(gMouseHook, nCode, wParam, lParam);
}

否，该挂钩过程必须在DLL中，以便可以将其注入到其他进程中.

No, the hook procedure needs to be in a DLL so that it can be injected into other processes.

这可能意味着您的挂接过程很慢.

That probably means your hook procedure is slow.
