问题描述

我在XPE中开发了OPC客户端,但是我无法获得该项目的价值.在同一项目中,它可以在专业XP中运行.

I developped OPC client in XPE, but i can not get the item value. The same project, it can run in professional XP.

// Instantiate a new IKDataSink20:
m_pIDataSink20 = new IKDataSink20 ();

// Add ourselves to its reference count:
m_pIDataSink20->AddRef ();

// Advise the server of our data sink:
hr = pCP->Advise (m_pIDataSink20,


hr值总是错误的.你能告诉我原因吗?

对于专业的XP和XPE,我们注册了相同的opc dll,但是结果不同!

For the professional XP and XPE, we registered the same opc dlls, but different result!
