NestedShapeCollection.AddOleObject(Stream, String, Image, PointF) Method

Adds an embedded OLE object to a shape group or a drawing canvas. The object is displayed in the document as an image.

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v20.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core

NuGet Packages: DevExpress.RichEdit.Core, DevExpress.WindowsDesktop.RichEdit.Core

Declaration

C#

NestedShape AddOleObject(
    Stream stream,
    string progId,
    Image presentation,
    PointF location
)

VB.NET

Function AddOleObject(
    stream As Stream,
    progId As String,
    presentation As Image,
    location As PointF
) As NestedShape

Parameters

Name	Type	Description
stream	Stream	A stream that contains data to embed in the document.
progId	String	Embedded content type. You can use constant fields of the OleObjectType class to set this value.
presentation	Image	The image that displays OLE object content.
location	PointF	An object that defines the object’s location (relative to the top left corner of the parent object). The Document.Unit property specifies measurement units.

Returns

Type	Description
NestedShape	The OLE object in the group or drawing canvas.

Remarks

The example below shows how to group two OLE objects. Use the ShapeCollection.InsertGroup method to create a shape group. The Shape.GroupItems property returns a collection of group elements. Call the AddOleObject methods to add OLE objects to the group.

C#

Document document = wordProcessor.Document;
// Set measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch;
// Insert a shape group.
Shape group = document.Shapes.InsertGroup(document.Range.Start);
// Access the collection of group items. 
var groupItems = group.GroupItems;
// Add the first OLE object to the group.
// This object contains data from an Excel worksheet.
using (Stream excelStream = File.Open(@"D:\ExcelWorkbook.xlsx", FileMode.Open))
{
    groupItems.AddOleObject(excelStream, OleObjectType.ExcelWorksheet,
        System.Drawing.Image.FromFile(@"Images\Spreadsheet.png"), new PointF(0f, 0f));
}
// Add the second OLE object to the group.
// The object links to an Excel chart sheet.
groupItems.AddOleObject(@"D:\ExcelChart.xlsx", OleObjectType.ExcelChart,
    System.Drawing.Image.FromFile(@"Images\ExcelChart.png"), new RectangleF(0.5f, 1.2f, 5f, 3.5f));

VB.NET

Dim document As Document = wordProcessor.Document
' Set measurement unit to inches.
document.Unit = DevExpress.Office.DocumentUnit.Inch
' Insert a shape group.
Dim group As Shape = document.Shapes.InsertGroup(document.Range.Start)
' Access the collection of group items. 
Dim groupItems As GroupShapeCollection = group.GroupItems
groupItems = group.GroupItems
' Add the first OLE object to the group.
' This object contains data from an Excel worksheet.
Using excelStream As Stream = File.Open("D:\ExcelWorkbook.xlsx", FileMode.Open)
    groupItems.AddOleObject(excelStream, OleObjectType.ExcelWorksheet, _
    System.Drawing.Image.FromFile("Images\Spreadsheet.png"), New PointF(0F, 0F))
End Using
' Add the second OLE object to the group.
' The object links to an Excel chart sheet.
groupItems.AddOleObject("D:\ExcelChart.xlsx", OleObjectType.ExcelChart, _
  System.Drawing.Image.FromFile("Images\ExcelChart.png"), New RectangleF(0.5F, 1.2F, 5F, 3.5F))
