Import Component Wizard
Go Up to Component Menu
Component > Import 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.
| Type of Component option | Description |
|---|---|
|
Import a Type Library |
Click to import a type library that is already registered on your system. This type library will be the ancestor of the component you are going to create. |
|
Import ActiveX Control |
Click to import an ActiveX Control that is currently registered on your system. This ActiveX Control will be the ancestor of the component you are going to create. |
|
Import .NET assembly |
Click to import a .NET assembly as a COM object. The GAC registered .NET assembly that you select will be the ancestor of the component you create. |
Contents
Registered Type Libraries page, ActiveX Controls page, or .NET Assemblies page
Depending on the type of component you selected in the previous step (on the Import Component page), this page will show a list of registered type libraries, a list of ActiveX Controls, or a list of .NET assemblies in the Global Assembly Cache.
Note: The Import Component wizard looks only at the 32-bit Registry. So when running on a 64-bit system, you must use TLIBIMP.EXE directly if you wish to import a 64-bit specific type library or ActiveX control.
