DAX Not supported

Hello,
i'am develop a software which call an activeX Object.
When i try to open my ActiveX Object, following error message appear :
"DAX Error -- interface not supported"
 
I've debug my ActiveX. The Line which cause this error is following function :
m_IADD := CreateComObject(stringToGUID('Buep.Buep')) as IAdd;
 
My activeX run correctly when she's called by softwares such as Delphi, C++ or VB. But, Labview failed.
 
I don't know what i make wrong. Someone could help me ?
 
Thanks

Hy woully,

It seems as you are developing your dll with Delphi.
"DAX Error -- interface not supported" is not a LabVIEW error.
Are you generating controls?
Are you using some 3rd party ocx?

Please verify that STDVCL32.DLL AND your type library are registered.
See http://www.delphi32.com/info_facts/faq/faq_132.asp

Hello,

it's true i use Delphi.

I know the problem now. My activeX called functions of other activeX. The called functions have IUnknown Interface, and that's the problem. I have a compatibility error.

Thanks for your answer.

Woully
