TLB problem

While implementing a ActiveX DLL, I've used COM interfaces, defined in interfaces.tlb file.
After this, I need to somehow register information from the TLN file. Regsvr32 dosn't do the job.
How can I distribute information from TLB?
Thanks!

What you need register from TLB file?
Run OleView
Select File->View typelib
Is This what you need?

================================
what you need to register for a COM/ACTIVEX component are through calling an exported function DllRegisterServer() of that dll.
Generally speaking,TLB is used by compilers to extract prototype of interfaces ,member functions,class definitons and so on to support type checking or so when you use that dll.
Also some tools for viewing com objects.
 

->How can I distribute information from TLB?
No need to store data in TLB into registry .All you need it ship it together with server or contain it into server as resource.

Could you provide me with some more precise example? Do I need to add some code in DllRegisterServer(), or this is done automaticly (after importing *.TLB via #import directive)?
I've also tried to use LoadTypeLib() API to load and later register my TLB, but it always returns with CANTLOADLIBRARY error (although path, one and only parameter, is correct). Don't know what's the problem... Do you have any ideas?
Thanks!

Three Considerations for Containers

Containers like Docker and Rocket are getting more popular every day. In my conversations with customers, they consistently ask what containers are and how they can use them in their environment. If you’re as curious as most people, read our article on Experts Exchange.

===============================

I will try to elaborate later.

You have to add the interfaces.tlb to the .rc file and then register it.

Follow these steps:
1) Open "Resource Includes" dialog box ( View | Resource Includes… menu item )
2) Add to the ListBox "Compile-time directives" the following line:
  2 TYPELIB " interfaces.tlb "
3) in DllRegisterServer() add register type library through calling
  _Module.RegisterTypeLib( _T("\\2" ));
