LoadLibray找不到指定的模块？

HMODULE m_hNewDev = ::LoadLibrary("NEWDEV.dll");

做了一个Storage控制程序，
运行这句就出现找不到指定的模块~！

char szWindowsDir[MAX_PATH] = {0};
GetWindowsDirectory(szWindowsDir,MAX_PATH);
strcat(szWindowsDir,"\\INF\\USBSNX2K.INF\0");
BOOL bRebootRequired = FALSE;
SetupDiDestroyDeviceInfoList(DeviceInfoSet);
HMODULE m_hNewDev = ::LoadLibrary("NEWDEV.dll");
if (!m_hNewDev)
return SNX_ERROR;
UpdateDriver updateDriver;
updateDriver = (UpdateDriver) GetProcAddress(m_hNewDev,"UpdateDriverForPlugAndPlayDevicesA");
if (!updateDriver)
{
FreeLibrary(m_hNewDev);
return SNX_ERROR;
}
bool brtn = updateDriver(0,
(char*)buffer,
szWindowsDir,
INSTALLFLAG_FORCE,
&bRebootRequired);
FreeLibrary(m_hNewDev);
if(bRebootRequired)
return SNX_REBOOT;
return SNX_OK;
}
}
SetupDiDestroyDeviceInfoList(DeviceInfoSet);
return SNX_ERROR;

着句之前的操作正常~！

NEWDEV.dll是C:\WINNT\system32下的.
