Dim SubStorageName As System.String
Dim IsStoring As System.Boolean
Dim value As System.Object
 
value = instance.Get3rdPartyStorageStore(SubStorageName, IsStoring)
C# 
System.object Get3rdPartyStorageStore( 
   System.string SubStorageName,
   System.bool IsStoring
)
C++/CLI 
System.Object^ Get3rdPartyStorageStore( 
&   System.String^ SubStorageName,

Name of the storage

Return Value

Pointer to Unknown (see Remarks)

Example

Remarks

After calling this method, you must call ISwDMDocument19::Release3rdPartyStorageStore. Otherwise, the third-party node might remain locked and prevent future access.

NOTE: The name given to the storage should be registered so that no conflicts occur. Once registered, the storage name is reserved exclusively for your application.

Passing the unique ID string and a flag to determine if data is being stored or loaded returns an IUnknown pointer. You must then use QueryInterface() to get the Microsoft.VisualStudio.OLE.Interop.IStorage interface. The storage object is used for serialization and then released in the third-party code.

The IStorage object used by the third party is written under an IStorage object called ThirdPtyStore in the SOLIDWORKS compound document. Each third party writes to a single IStorage whose name is assigned by SOLIDWORKS.

SwRootStorage --|

        |-- ThirdPtyStore --|

                |-- <SW Assigned IStorage name 1> --|

                                  |-- <Application 1 IStream name 1>

                                  |-- <Application 1 IStream name 2>

                |-- <SW Assigned IStorage name 2> --|

                                  |-- <Application 2 IStream name 1>

                                  |-- <Application 2 IStream name 2>

                                  |-- <Application 2 IStorage name 2> --|

                                                     |-- <Application 2 IStream name 3>

NOTE: If you are using serialization, then be careful with the standard MFC macros. Otherwise, you may get a message like Unexpected File Format after your application is unloaded. One way of using IMPLEMENT_SERIAL:

IMPLEMENT_SERIAL( CCustomAttr, CObject, VERSIONABLE_SCHEMA|0 )
