Arguably the most important interface for an OLE object. For example, it allows the container to inform the object of its site, initialize the object from data, to open and close it, to query and set the size of the object, to ask for notifications on the container's AdviseSink and to execute objects defined as "verbs" on the object. These ...
OLE Object Linking and Embedding allows a Windows application to control another to enable it to format or calculate data. This may take on the form of "embedding" where an application uses another to handle a task that it is more suited to, for example a PowerPoint presentation may be embedded in an Excel spreadsheet or vice versa.
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft that allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE .
If an application wishes to persist several data objects to a file, one way to do so would be to open an IStorage that represents the contents of that file and save each of the objects within a single IStream. One way to accomplish the latter is through the standard COM interface IPersistStream. OLE depends heavily on this model to embed ...
For example, Excel now exposes an extensive OLE Automation object model, which is the recommended method for communicating with Excel. The technique is, however, still in use, particularly for distribution of financial data. [ 4 ]
Microsoft Graph supports many different types of charts, but its output is dated. Office 2003 was the last version to use Microsoft Graph for hosting charts inside Office applications as OLE objects. Office 2007 – specifically, Excel 2007 – includes a new integrated charting engine, and the charts are native to the applications. The new ...
The Microsoft OLE DB Provider for ODBC, or MSDASQL, was an OLE DB provider for allowing ActiveX Data Objects access to databases via any ODBC driver. Microsoft supplied several OLE-DB providers (for the Indexing Service, Active Directory , Jet, SQL Server, Oracle ( MSDAORA [ 28 ] ) and Internet Publishing), however unless otherwise directed ...
References to the different libraries must be created within the VBA client before any of the methods, objects, etc. become available to use in the application. This is achieved through what is referred to as Early or Late Binding. These application objects create the OLE link to the application when they are first created.
