Register com interop installshield

Registration Type. None —Select this option if you do not want the selected file to be registered on the target machine. This is the default setting for all files.

This is the recommended way to register COM objects. Self-Registration —If your file supports self-registration, you can choose this option. Note that self-registration is not as reliable as having Windows Installer register and unregister the file with extracted COM information.

Scan at Build. None —Choose this if you do not want to scan for. NET dependencies or properties. Properties Only —Scan only for. NET properties. Privacy policy. The topic describes methods to enable interoperability between C managed code and unmanaged code. Platform invoke is a service that enables managed code to call unmanaged functions that are implemented in dynamic link libraries DLLs , such as those in the Microsoft Windows API.

It locates and invokes an exported function and marshals its arguments integers, strings, arrays, structures, and so on across the interoperation boundary as needed. Calling unmanaged code that is outside the CLR bypasses this security mechanism, and therefore presents a security risk. For example, unmanaged code might call resources in unmanaged code directly, bypassing CLR security mechanisms.

For more information, see Security in. NET language. Unlike other. Finally, you add a reference to the assembly in your C project and use the wrapped objects just as you would use other managed classes. Locate a COM component to use and register it. Use regsvr When you add the reference, Visual Studio uses the Tlbimp. NET Framework application can generate an interop assembly, doing so creates a problem. Each time a developer imports and signs a COM type library, that developer creates a set of unique types that are incompatible with those imported and signed by another developer.

The solution to this type incompatibility problem is for each developer to obtain the vendor-supplied and signed primary interop assembly. If you plan to expose third-party COM types to other applications, always use the primary interop assembly provided by the same publisher as the type library it defines. In addition to providing guaranteed type compatibility, primary interop assemblies are often customized by the vendor to enhance interoperability.

Even if you do not plan to expose third-party COM types, using the primary interop assembly can ease the task of interoperating with COM components. However, this strategy provides no insulation from changes a vendor might make to types defined in a primary interop assembly.

When your application requires such insulation, generate your own interop assembly instead of using the primary interop assembly. You must register all acquired primary interop assemblies on your development computer before you can reference them with Visual Studio. Visual Studio looks for and uses a primary interop assembly the first time that you reference a type from a COM type library. If Visual Studio cannot locate the primary interop assembly associated with the type library, it prompts you to acquire it or offers to create an interop assembly instead.
