It seems rather difficult if you'd like to handle many new idl-files in LaserOS - currently I only find a way to import one after another, but no bulk import or (later). Solution for the problem that ILDA files can't be recognized by ShowNET interfaces.

ILD File Summary
Our most recent information indicates that ILD files are associated with two unique file types (the most prevalent being the Interlace Logo Designer Picture Image format) and can be viewed primarily with Recoil, including one other known software applications (listed below). The ILD File Extension are listed predominantly as Data Files, while in other circumstances they can be Raster Image Files.
The ILD File Extension can be viewed on the Windows, Mac, and Android operating systems. They are supported on both desktop and mobile devices. With a Popularity Rating of 'Low', these files are not very common to your average computer user.

Introduction
MIDL (Microsoft Interface Definition Language) is used for describing COM objects. A file that contains interface and type library definitions is called an IDL file, and has a .idl file name extension.
The Interface Definition Language (IDL) is not a programming language, but a descriptive language to describe the interfaces being implemented by objects. IDL files are similar to C++ header files.
Contents of an IDL file
In any IDL file, there can be one or more interface definitions defined as part of a module. Each interface definition is composed of an interface header and an interface body. The IDL interface header specifies information about the interface as a whole.
The IDL interface body contains data types used in remote procedure calls and the function prototypes for the remote procedures. The interface body can also contain imports, pragmas, constant declarations, and type declarations. (Each interface body may contain methods, properties, variables/constants, enums etc. In other words, everything which needs to be exposed from the interface will be there in the IDL file.)
Structure of an IDL file
Interface header example
An iInterface header contains attributes that are platform-independent. Attributes in the interface header are global to the entire interface. These attributes are enclosed in square brackets at the beginning of the interface definition. Each attribute has its own meaning:
Object
: This indicates that it is a COM interface.Uuid
: Represents a universally unique identifier (UUID) that is assigned to the interface and that distinguishes it from other interfaces. Each interface, class, and type library must be identified with its own unique identifier.Dual
: Thedual
attribute identifies an interface that exposes properties and methods throughIDispatch
and VTBL.Nonextensible
: This specifies that theIDispatch
implementation includes only the properties and methods listed in the interface description, and that it cannot be extended with additional members at runtime.Helpstring
: A character string that is used to describe the element to which it applies.Pointer_default
: Specifies the default pointer attribute for all pointers except the top-level pointers that appear in the parameter lists.
For more information: MSDN.
Interface body example
ILogManager
– The interface name.IDispatch
– The COM base class.Id(1)
– The unique ID of the method.Helpstring
- The character string which describes this method.HRESULT
– Returns the error code.Initialize
– Method name.In
– Specifies the parameter to be passed from the calling procedure to the called procedure.Out
- The parameter that specifies data that is passed back to the caller. Using both directional attributes on one parameter specifies that the parameter is used both to send data to the method and to pass data back to the caller.
Type library
A type library is an essential part of a component, providing information to the compiler about the classes, interfaces, enumerations, and so on, included in the component. Type library files have the extension .tlb.
Example of a type library
The library statement defines the
MyTypeLibraryFileLib
type library, which has its own uuid
, helpstring
, and version attributes. The coclass
statement defines an entirely new component class, LogManager
, that includes a previously defined interface, ILogManager
.MIDL compiler
An MIDL compiler processes the IDL file and creates a type library, a header, and proxy files.
A type library is a binary file that describes the COM object or COM interfaces, or both.
Creating a TLB file from an IDL file
Save the IDL file and then use the MIDL compiler to generate the TLB file. From the command line, enter:
The '/h' switch will produce a C/C++ header file as well.
