Trying to open a visa session on PXI device by using visa com with c++ visual studio 6 : class not registered error

[nbro1c]

When I try to open a session on a PXI device I get a com error : Class not registered.

I use visa com (GlobMgr.dll) on visual studio 6 c++ program:

IResourcemanagerPtr m_piResourceManager(CLSID_ResourceManager);

CString pPxiResources = "PXI2::10::INSTR";

IVisaSessionPtr piVisaSession = m_piResourceManager->Open(p_pPxiResources.AllocSysString(),NO_LOCK,0,"");

But when I try to open a session on an ASRL*? device I haven't got problemn.

Could you help me please.

Hi,
