隐藏DLL 和 修改MFC窗体类名(转）

void HideDll()
{
    HMODULE hMod = ::GetModuleHandle("MyHook.dll");
    PLIST_ENTRY Head,Cur;
    PPEB_LDR_DATA ldr;
    PLDR_MODULE ldm;
    __asm
    {
        mov eax , fs:[0x30]
        mov ecx , [eax + 0x0c] //Ldr
        mov ldr , ecx
    }
    Head = &(ldr->InLoadOrderModuleList);
    Cur = Head->Flink;
    do
    {
        ldm = CONTAINING_RECORD( Cur, LDR_MODULE, InLoadOrderModuleList);
        //printf("EntryPoint [0x%X]\n",ldm->BaseAddress);
        if( hMod == ldm->BaseAddress)
         {
            ldm->InLoadOrderModuleList.Blink->Flink =

MFC 改变窗口类名

1,改变窗口类名：比如：MyClassName是自己想设置的类名
方法：打开资源视图，右击外挂窗口，属性改掉ClassName属性，若它为灰色，右击.rc文件改mfc Mode属性为false,再改
2，改变后在CTestCpp中的InitInstance()注册该窗口类名
WNDCLASS wc;

// 获取窗口类信息。MFC默认的所有对话框的窗口类名为 #32770 
::GetClassInfo(AfxGetInstanceHandle(), _T("#32770"), &wc);

// 改变窗口类名 
wc.lpszClassName = _T("MyClassName");

// 注册新窗口类，使程序能使用它 

 AfxRegisterClass(&wc);

AfxRegisterClass(&wc);
