AxImporter Class

AxImporter Class

Imports ActiveX controls and generates a wrapper that can be accessed by a designer.


Namespace:  System.Windows.Forms.Design
Assembly:  System.Design (in System.Design.dll)

public class AxImporter

The AxImporter type exposes the following members.

Public methodAxImporterInitializes a new instance of the AxImporter class.

Public propertyGeneratedAssembliesGets the names of the assemblies that are generated for the control.
Public propertyGeneratedSourcesGets the names of the source files that were generated.
Public propertyGeneratedTypeLibAttributesGets the attributes for the generated type library.

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGenerateFromFileGenerates a wrapper for an ActiveX control for use in the design-time environment.
Public methodGenerateFromTypeLibrary(UCOMITypeLib)Generates a wrapper for an ActiveX control for use in the design-time environment.
Public methodGenerateFromTypeLibrary(UCOMITypeLib, Guid)Generates a wrapper for an ActiveX control for use in the design-time environment.
Public methodStatic memberGetFileOfTypeLibGets the path and file name to the specified type library.
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

To generate an ActiveX wrapper for an ActiveX control, first create or obtain an instance of the AxImporter class. The AxImporter constructor accepts an AxImporter.Options object, which sets options for the importer, such as the filename for the wrapper .dll to generate and the output directory to generate the wrapper to. To generate the ActiveX wrapper, call the appropriate Generate method. To generate from a file, call GenerateFromFile. To generate from a type library, call GenerateFromTypeLibrary. The string that is returned will consist of an assembly qualified name (example: "Namespace.Type,Assembly") for the type an ActiveX wrapper was generated for. The wrapper for the ActiveX control will be generated in the .dll file specified in the outputName property of the AxImporter.Options passed to the AxImporter constructor. The type can be loaded or queried using System.Reflection and treated as an ordinary managed type. You can also call the GetOcx method of the type to retrieve a COM interface to the object, if the object supports this.
