有点初级的问题请教各位大虾VC的(100分)

我用一简单的HELLOWORLD程序如下用LOADLIBRARY（）可以运行了但不能正常运行请大虾帮忙看看
//DLL程序
#include "mydll2.h"
BOOL APIENTRY DllMain( HINSTANCE hModule,
DWORD reason,
LPVOID lpReserved
)

{
switch(reason)
{
case DLL_PROCESS_ATTACH:
g_hinstDll=hModule;
break;
}
return TRUE;
}

static LRESULT WINAPI Hook_HookProc(int ncode,WPARAM wparam,LPARAM lparam)
{
LRESULT lResult=CallNextHookEx(g_hhook,
ncode,wparam,lparam);
switch(ncode)
{
case WM_MOUSEMOVE:
MessageBox(NULL,"HELLO",NULL,MB_OK);
break;
}
return(lResult);
}
BOOL WINAPI Hook_Start(HWND hwnd)
{
HHOOK hhook;
if(g_hhook!=NULL)
return(FALSE);
g_hwnd=hwnd;
hhook=SetWindowsHookEx(WH_GETMESSAGE,
Hook_HookProc,g_hinstDll,0);
g_hhook=hhook;
return(g_hhook!=NULL);
}
BOOL WINAPI Hook_stop()
{
BOOL fok=TRUE;
if(g_hhook!=NULL)
{
fok=UnhookWindowsHookEx(g_hhook);
g_hhook=NULL;
}
return(fok);
}

事情很急，请伸出援助之手：））））[]
