请问大使，在dll中怎么样加载资源，谢谢!

[czh306]

在dll中采用如下语句加载资源出错，为什么？
BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved
)
{
LPWORD pGBTable=NULL;
LPWORD pBIGTable=NULL;
HRSRC hRes;
HGLOBAL hGBTable=NULL;
HGLOBAL hBIGTable=NULL;

switch (ul_reason_for_call)
{
case DLL_PROCESS_ATTACH:
hRes=FindResourceNULL,"GBTOBIG",RT_RCDATA);
hGBTable=LoadResource(0,hRes);
pGBTable=(LPWORD)LockResource(hGBTable);
break;
}
return TRUE;
}
