编译时出错-从DWORD到LPCVOID的转换

我发现了这段代码,用于注入dll文件并从中调用函数。我有一个exe和源代码。 exe工作正常,但是当我尝试编译源代码时,出现此错误:

LoadDll.cpp: In Funktion »bool ExecuteRemoteThread(HANDLE, BOOL, BOOL, wchar_t*, wchar_t*)«:
LoadDll.cpp:313:62: Fehler: ungültige Umwandlung von »DWORD (__attribute__((__stdcall__)) *)(RemoteThreadBlock*) {aka long unsigned int (__attribute__((__stdcall__)) *)(RemoteThreadBlock*)}« in »LPCVOID {aka const void*}« [-fpermissive]
In file included from c:\mingw\bin\../lib/gcc/mingw32/4.7.2/../../../../include/windows.h:50:0,
                 from LoadDll.cpp:16:
c:\mingw\bin\../lib/gcc/mingw32/4.7.2/../../../../include/winbase.h:2215:24: Fehler:   Argument 3 von »BOOL WriteProcessMemory(HANDLE, LPVOID, LPCVOID, SIZE_T, SIZE_T*)« wird initialisiert [-fpermissive]

可以在以下位置找到源代码:https://pastebin.com/AuZpy57U

错误似乎在第313行

if ( ! WriteProcessMemory( hProcess, p, &RemoteThread, 0, 0 ) )

希望您能帮助我进行编译。

1 个答案:

答案 0 :(得分:1)

if ( ! WriteProcessMemory( hProcess, p, &RemoteThread, 0, 0 ) )

您必须转换第三个参数:

if ( !WriteProcessMemory( hProcess, p, reinterpret_cast<LPCVOID>(&RemoteThread), 0, 0 ) )

更新:

要摆脱undefined reference to 'WinMain@16',您应该使用

int main()
{
    int argc;
    wchar_t **argv = CommandLineToArgvW(GetCommandLineW(), &argc);

    // ...

代替

int wmain(int argc, wchar_t *argv[])
{
    // ...
