This document is archived and information here might be outdated. Recommended version. |
An editor extension for creating and editing annotation features.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
| Interfaces | Description |
|---|---|
| IAnnotationEditExtension | Provides access to members that control annotation feature editing. |
| IEditEvents | Provides access to editor events. Implement it to listen for specific events that occur during an edit session. |
| IEditEvents2 | Provides access to more editor events. Implement it to listen for specific events that occur during an edit session. |
| IEditSketchExtension | Provides access to members that extend the edit sketch. |
| IEditSketchExtension2 | Provides access to members that extend the edit sketch. |
| IExtension (esriSystem) | Provides access to members that define an extension. |
| ISupportErrorInfo (esriSystem) |
The AnnotationEditExtension is an editor extension to manage and create Geodatabase annotation features. The primary interface IAnnotationEditExtension can be accessed using IEditor::FindExtension and the CLSID for "esriEditor.AnnotationEditExtension".
The following C# code illustrates how to acquire a reference of type IAnnotationEditExtension to the AnnotationEditExtension object.
public void GetAnnotationEditExtensionByCLSID()
{
//You can get app from ICommand :: OnCreate() hook parameter
UID editorUid = new UIDClass();
editorUid.Value = "esriEditor.Editor";
IEditor editor = app.FindExtensionByCLSID(editorUid) as IEditor;
UID extUid = new UIDClass();
extUid.Value = "esriEditor.AnnotationEditExtension";
IAnnotationEditExtension annoExt = editor.FindExtension(extUid) as IAnnotationEditExtension;
}
The following VBNet code illustrates how to acquire a reference of type IAnnotationEditExtension to the AnnotationEditExtension object.
Public Sub GetAnnotationEditExtensionByCLSID()
'You can get app from ICommand :: OnCreate() hook parameter
Dim editorUid As UID = New UIDClass()
editorUid.Value = "esriEditor.Editor"
Dim editor As IEditor = TryCast(app.FindExtensionByCLSID(editorUid), IEditor)
Dim extUid As UID = New UIDClass()
extUid.Value = "esriEditor.AnnotationEditExtension"
Dim annoExt As IAnnotationEditExtension = TryCast(editor.FindExtension(extUid), IAnnotationEditExtension)
End Sub
