An OLEControl placed in a window can contain an object, such as a spreadsheet or word processing document, that was created by an OLE-aware application. The PowerBuilder application's user can activate the object and edit it in the application in which it was created (the server application).
OLE controls are displayed in the OLE tab of the Browser as Insertable Objects.
For more information about using OLE in an application, see Using OLE in an Application in Application Techniques.

|
|
ClassDefinition |
PowerObject |
An object of type PowerObject containing information about the class definition of the object or control. |
|
ClassLongName |
String |
(Read-only) The long name for the server application associated with the OLE object in the control. |
|
ClassShortName |
String |
(Read-only) The short name for the server application associated with the OLE object in the control. |
|
omContentsAllowed |
Specifies whether the OLE object in the control must be embedded or linked or whether either method is allowed when Insert is called at runtime. |
|
|
String |
User-readable name for your OLE control when the control is activated in place. This name is displayed in OLE dialog boxes and windows that show the object's name. If you do not specify a value, the name of the control (such as ole_1) is used for DisplayName. |
|
|
omDisplayType |
Specifies how the OLE object will be displayed in the control. The control can display the actual contents or an icon to represent the object, or the document can be displayed as an ActiveX document. |
|
|
DocFileName |

|
Boolean |
Specifies whether PowerBuilder puts the control automatically into Drag mode. Values are: TRUE -- When the control is clicked, the control is automatically in Drag mode.

|
|
String |
Specifies the name of the stock icon or the file containing the icon you want to display when the user drags the control (the ICO file). The default icon is a box the size of the control.

|
LinkItem |
String |
(Read-only) The entire link name of the item to which the object is linked. For example, if the object is linked to C:\FILENAME.XLS!A1:B2, then LinkItem would contain C:\FILENAME.XLS!A1:B2. |
|
omLinkUpdateOptions |
Specifies how a linked object in the control is updated. If automatic, the link is updated when the object is opened and whenever the object changes in the server application. If manual, the link is not updated. |
|
|
Object |
omObject |
Used in scripts to apply server commands to the linked or embedded OLE object within the control. |
|
ObjectData |
Blob |
If the object is embedded, the object itself is stored as a blob in the ObjectData property. If the object is linked, this property contains the link information and the cached image (for display). |
|
ParentStorage |
omStorage |
(Read-only) Specifies the parent storage. |
|
String |
Specifies the name of the stock pointer or the file containing the pointer used for the control. |

Boolean |
Specifies whether the control is resizable. Values are: TRUE -- Control is resizable. FALSE -- Control is not resizable. |
|
|
SizeMode |
SizeMode (enumerated) |
Specifies the size mode for the OLE document. Choices are: Clip! -- The object's image displays full size. If it is larger than the OLE control, the image is clipped by the control's borders. Stretch! -- The object's image is resized to fit into and fill the OLE container control. This is the default value. |
|
Integer |
Specifies tab value of the control within the window (0 means the user cannot tab to the control). |
