virtual boolean MCCOMAPI IShComponentUtilities::AskForParams (  IShParameterComponent *  component  )  [pure virtual]
 

Allows a component to present a dialog box asking for values for its parameters. Used, for example, when exporting a file, to present export options appropriate to the file format we're exporting to.

Parameters:
component Pointer to the component to ask for its parameters

virtual MCCOMErr MCCOMAPI IShComponentUtilities::CoCreateInstance (  const MCCLSID &  rclsid,
IMCUnknown *  pUnkOuter,
uint32  dwClsContext,
const MCIID &  riid,
void **  ppv
)  [pure virtual]
 

Manually creates a component. 

           TMCCountedPtr<I3DShInstance> instance;
           gComponentUtilities->CoCreateInstance(CLSID_StandardInstance, NULL, MC_CLSCTX_INPROC_SERVER, IID_I3DShInstance, (void **) &instance);
           instance->Set3DObject(masterObject);
Parameters:
rclsid Class ID of the component to create
pUnkOuter Pointer to the controlling Unknown object. Used for COM aggregation - this is the object that maintains the refcount.
dwClsContext Pass MC_CLSCTX_INPROC_SERVER here.
riid Interface ID for the interface we want
ppv Points to the resulting interface of the component created

virtual MCCOMErr MCCOMAPI IShComponentUtilities::CreateComponent (  IDType  familyID,
IDType  classID,
int32  version,
IShComponent **  component
)  [pure virtual]
 

Creates a specific version of a component by family ID and class ID

Parameters:
familyID Family ID of the component to create
classID Class ID of the component to create
version Version number of the component to create
component Returns a pointer to the IShComponent interface of the component created

virtual MCCOMErr MCCOMAPI IShComponentUtilities::CreateComponent (  IDType  familyID,
IDType  classID,
IShComponent **  component
)  [pure virtual]
 

Creates the most recent version of a component by family ID and class ID.

Parameters:
familyID Family ID of the component to create
classID Class ID of the component to create
component Returns a pointer to the IShComponent interface of the component created.

virtual MCCOMErr MCCOMAPI IShComponentUtilities::CreateDefaultComponent (  IDType  familyID,
IShComponent **  component
)  [pure virtual]
 

Creates a default instance of a component family.

Parameters:
familyID The family ID whose default component you want to create
component Returns a pointer to the component created

virtual MCCOMErr MCCOMAPI IShComponentUtilities::CreateIUnknown (  IDType  familyID,
IDType  classID,
IMCUnknown *  pUnkOuter,
IMCUnknown **  component
)  [pure virtual]
 

This is similar to CoCreateInstance, but creates the component instances by family and class ID. For example, CreateInstanceByID('gel ', 'blnd', &gel); creates a "blinds" gel.

Parameters:
familyID Family ID of the component to create
classID Class ID of the component to create
pUnkOuter Pointer to the controlling Unknown object. Used for COM aggregation - this is the object that maintains the refcount.
component Returns a pointer to the component created

virtual MCCOMErr MCCOMAPI IShComponentUtilities::FinishFileReading (   )  [pure virtual]
 

virtual MCCOMErr MCCOMAPI IShComponentUtilities::FinishFileWriting (   )  [pure virtual]
 

Resets the component writing mechanism when finished writing a file. You should call it before you call WriteComponent.

Note that this function is called by the shell when it is finishing writing to a file, so you only need to call it if you initiate the writing of the file.

virtual MCCOMErr MCCOMAPI IShComponentUtilities::GetComponentClassInfoArrayByFamilyID (  IDType  familyID,
TMCArray< TComponentClassInfo > &  componentClassInfoArray
)  [pure virtual]
 

Gets an array of TComponentClassInfo for the classes that are in a given family

Parameters:
familyID The family ID to query
componentClassInfoArray Returns the class information on the classes in the specified family

virtual MCCOMErr MCCOMAPI IShComponentUtilities::ReadComponent (  IShTokenStream *  stream,
IShParameterComponent **  component,
IDType  familyID
)  [pure virtual]
 

Reads a component from an IShTokenStream when its family ID keyword header has been read.

Parameters:
stream Pointer to the input stream
component Returns a pointer to the component read
familyID Family ID read

virtual MCCOMErr MCCOMAPI IShComponentUtilities::ReadComponent (  IShTokenStream *  stream,
IShParameterComponent **  component
)  [pure virtual]
 

Reads a component from an IShTokenStream

Parameters:
stream Pointer to the input stream
component Returns a pointer to the component read

virtual MCCOMErr MCCOMAPI IShComponentUtilities::ReadComponentData (  TMCiostream *  stream,
IShParameterComponent *  component
)  [pure virtual]
 

Reads a component's data from a TMCiostream.

Parameters:
stream Pointer to the input stream
component Pointer to the component whose data we would like to read

virtual MCCOMErr MCCOMAPI IShComponentUtilities::StartFileReading (   )  [pure virtual]
 

Resets the component reading mechanism when you start reading a file. Call it before you call RedComponent.

Note that it is called by the shell when starting to read a file, so you only need to call it if you initiate the reading of the file.

virtual MCCOMErr MCCOMAPI IShComponentUtilities::StartFileWriting (   )  [pure virtual]
 

Reset the component writing mechanism when you start writing a file. You should call it before you call WriteComponent.

Note that it is called by the shell when it starts to write a file, so you only need to call it if you initiate the writing of a the file.

virtual MCCOMErr MCCOMAPI IShComponentUtilities::WriteComponent (  IShTokenStream *  stream,
IDType  keyword,
IShParameterComponent *  component
)  [pure virtual]
 

Writes a component to an IShTokenStream, with a keyword header

Parameters:
stream Pointer to the output stream
keyword Keyword to write as header
component Pointer to the component to write

virtual MCCOMErr MCCOMAPI IShComponentUtilities::WriteComponent (  IShTokenStream *  stream,
IShParameterComponent *  component
)  [pure virtual]
 

Writes a component to an IShTokenStream

Parameters:
stream Pointer to the output stream
component Pointer to the component to write
