IGlobalAPI_KC Interface

GetCoreContext

Implements collection of global methods of DG Kernel software, independent of any particular control instance.

When a DG Kernel window was already created query this interface from IView or IModel, otherwise use the method below.

IGlobalAPI_KC is implemented (can be queried from) by KcApiComProxy object which can be created via COM, independently of any controls or views, including command line applications. KcApiComProxy object can be instantiated in COM-enabled development environments by using either its Class ID or Program ID (see below).  

In .NET environment DIObjGenerator can be created using standard new operator as (C# example):

       KernCADnet.KcApiComProxyClass kcApi = new KernCADnet.KcApiComProxyClass();
       IGlobalAPI_KC iApi = (IGlobalAPI_KC)kcApi;

Actual name of the wrapper class might be different in different versions of the development environment. Refer to Object Browser in the project after adding a reference to the KernelCADnet component (See Patch Tutorial).

In C++ the KcApiComProxy can be instantiated by using its Class ID and call to CoGetClassObject() COM function.

In native Visual Basic an instance of the class can be created using the Program ID and CreateObject() API as follows:

            Dim iGlobApi As IGlobalAPI_KC

            Set iGlobApi = CreateObject("KERNELCAD.KCAPI.1")

KcApiComProxy implements a single IGlobalAPI_KC interface, which can be obtained via call to CreateInstance() COM API in C/C++ or a cast in other languages.

Class IDs

.NET:

Class ID:

// {1BAD07C5-A93E-4b10-8AE7-B3215A5F6917}
static const GUID CLSID_KcApiComProxy = 
{ 0x1bad07c5, 0xa93e, 0x4b10, { 0x8a, 0xe7, 0xb3, 0x21, 0x5a, 0x5f, 0x69, 0x17 } };

Program ID:  

KERNELCAD_NET.KCAPI.1

Native:

Class ID:

// {DA3EF301-E066-42EE-BCF4-4EAFCB41DCB5}

HRESULT LockInitialisationContext(IControlInitialisationContext_KC** context)

Parameters

context-[out] the returned context

Remarks:

The method acquires exclusive access to the Component Initialisation Context. Call context.ReleaseContext() when it is no longer needed to allow access to it by other threads. If the context cannot be accessed in 5 seconds the method returns null

HRESULT LaunchExplorer(IModel* model, IView* view)

Opens Model Explorer window for the model

HRESULT GetReferenceCount(IUnknown* anInterface, [out, retval] int* count)

Returns the current reference count for the object, which implements interface anInterface. See lso Memory Management

HRESULT AddRefUnsafe(IUnknown* anInterface, [out, retval] int* count)

Increments the reference count for the object, which implements interface anInterface and returns the incremented value. Warning: This method should only be used in exceptional situations as a temporary workaround. See lso Memory Management

HRESULT ReleaseUnsafe(IUnknown* anInterface, [out, retval] int* count)

Decrements the reference count for the, object which implements interface anInterface and returns the new value. When the retuned value is 0 the object has been deleted and the interface must not be used. Warning: This method should only be used in exceptional situations as a temporary workaround. See lso Memory Management

HRESULT GetTechnology(char* name, [out, retval] ITechnology_DG** technology)

Not supported in v6.1

HRESULT GetCoreContext([out, retval] IDictionary_DG** context)

This method is available in v6.1.5160 or later. Returns set of parameters used in pure geometric operations. In v6.1 it contains only parameters relevant to BRep to Mesh geometry conversion. Details.
