'LPVOID': 非法将此类型用作表达式

Question

I don't know the very vell the Dynamic-Link-Library if i ask the bad question sorry guys

Im taking the -> 'LPVOID': illegal use of this type as an expression

#include "pch.h"
#include <iostream>
#include <Windows.h>

Library

HANDLE handle;
HWND hwnd;
DWORD pID;

Some requires for giving the handle game

template <class T>
T Read(DWORD address)
{
    T VALUE;
    ReadProcessMemory(handle, (LPVOID), &VALUE, sizeof(T), 0);
    return VALUE;
}

RPM Template

void readingvariables()
{
    // 00DB0000 - sauerbraten.exe
    DWORD localplayer = Read<DWORD>(0x00DB0000 + 0x213EA8);
    int health = Read<int>(localplayer + 0x15C);
    printf("Health :", health);
}

Reading variables there is here

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
        readingvariables();
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

Last here to attach dll

Okey guys im waiting answer have good day:)

Answer 1

You are not calling ReadProcessMemory() correctly. You are passing it a type where a memory address is expected. You are ignoring the address parameter being passed in to Read() , that is what you should be type casting to LPVOID , eg:

template <class T>
T Read(DWORD address)
{
    T VALUE;
    if (!ReadProcessMemory(handle, (LPVOID)address, &VALUE, sizeof(T), NULL))
    {
        // error handling...
    }
    return VALUE;
}

Answer 2

Your problem is here:

ReadProcessMemory(handle, (LPVOID), &VALUE, sizeof(T), 0);

The second argument is just (LPVOID) , which is just a type, but it needs to be an expression. Are you trying to cast something to LPVOID ?

Perhaps you meant (LPVOID)&VALUE or maybe (LPVOID)0 ?

The error message issued to you by your compiler should have given you this line number.
