我手上有一些代码可以全局打印鼠标坐标(使用WH_MOUSE_LL).我的目标是使用WH_MOUSE而不是WH_MOUSE_LL,因为(从我读过的内容)它更快.我已经阅读了论坛,当使用WH_MOUSE时,它需要在DLL中声明以实现全局效果,但是,当在程序中使用时,它应该在声明它的应用程序上工作,但它不起作用(它当我只是将WH_MOUSE_LL更改为WH_MOUSE时,不打印任何内容.这是代码:

#define _WIN32_WINNT 0x0400
#pragma comment( lib, "user32.lib" )

#include <windows.h>
#include <stdio.h>

HHOOK hMouseHook;

LRESULT CALLBACK mouseProc (int nCode, WPARAM wParam, LPARAM lParam)
{
    MOUSEHOOKSTRUCT * pMouseStruct = (MOUSEHOOKSTRUCT *)lParam;
    if (pMouseStruct != NULL){
        if(wParam == WM_LBUTTONDOWN)
        {
            printf( "clicked" ); 
        }
        printf("Mouse position X = %d  Mouse Position Y = %d\n", pMouseStruct->pt.x,pMouseStruct->pt.y);
    }
    return CallNextHookEx(hMouseHook, nCode, wParam, lParam);
}

DWORD WINAPI MyMouseLogger(LPVOID lpParm)
{
    HINSTANCE hInstance = GetModuleHandle(NULL);

    // here I put WH_MOUSE instead of WH_MOUSE_LL
    hMouseHook = …
