ComponentImport Component 

Use this wizard to import a type library, an ActiveX Control, or a .NET assembly as a component in your project. 

If you select Import Component with no project open, you need to choose VCL for C++ Win32 or VCL for Delphi Win32.  

The following files are generated by the Import Component wizard:

  • For Delphi: *+TLB.dcr, *_TLB.pas.
  • For C++: *_OCX.dcr, *_OCX.cpp, *_OCX.h, *_TLB.cpp, *_TLB.h.
Note: Not all of the features described here are present for every instance of the wizard.
