Hi Eric,
I do have a issue with embedding Excel Worksheet objects into Word documents concerning the size of this objects. The size of the embedded object is calculated via the generated emfpicture of object.
The embedded Excel objects are .xlsxfiles (also open xmlfiles).I found a related topic but the issue which is currently unresolved at:
https://social.msdn.microsoft.com/Forums/enUS/9635fca8a7264ab39068ffc6ceb00a14/openxmlembedexceloleobjectinworddocument?forum=os_binaryfileEmbedding Visio Drawings as object are going correctly. So I think it has to do with embedding Excel into Word.
Hereby code snippet for embedding an object:
Dim embeddedObject As EmbeddedObject = New EmbeddedObject() With {.DxaOriginal = widthInTwips.ToString(), .DyaOriginal = heightInTwips.ToString()}
Dim shapetypeId As String = DateTime.Now.Ticks.ToString() ‘”_x0000_t75″
Dim shapetype1 As V.Shapetype = New V.Shapetype() With {.Id = shapetypeId, .CoordinateSize = “21600,21600”, .Filled = False, .Stroked = False, .OptionalNumber = 75, .PreferRelative = True, .EdgePath = “m@4@5L@4@11@9@11@9@5xe”}
Dim stroke1 As V.Stroke = New V.Stroke() With {.JoinStyle = V.StrokeJoinStyleValues.Miter}Dim formulas1 As V.Formulas = New V.Formulas()
Dim formula1 As V.Formula = New V.Formula() With {.Equation = “If lineDrawn pixelLineWidth 0”}
Dim formula2 As V.Formula = New V.Formula() With {.Equation = “sum @0 1 0”}
Dim formula3 As V.Formula = New V.Formula() With {.Equation = “sum 0 0 @1”}
Dim formula4 As V.Formula = New V.Formula() With {.Equation = “prod @2 1 2”}
Dim formula5 As V.Formula = New V.Formula() With {.Equation = “prod @3 21600 pixelWidth”}
Dim formula6 As V.Formula = New V.Formula() With {.Equation = “prod @3 21600 pixelHeight”}
Dim formula7 As V.Formula = New V.Formula() With {.Equation = “sum @0 0 1”}
Dim formula8 As V.Formula = New V.Formula() With {.Equation = “prod @6 1 2”}
Dim formula9 As V.Formula = New V.Formula() With {.Equation = “prod @7 21600 pixelWidth”}
Dim formula10 As V.Formula = New V.Formula() With {.Equation = “sum @8 21600 0”}
Dim formula11 As V.Formula = New V.Formula() With {.Equation = “prod @7 21600 pixelHeight”}
Dim formula12 As V.Formula = New V.Formula() With {.Equation = “sum @10 21600 0″}formulas1.Append(formula1)
formulas1.Append(formula2)
formulas1.Append(formula3)
formulas1.Append(formula4)
formulas1.Append(formula5)
formulas1.Append(formula6)
formulas1.Append(formula7)
formulas1.Append(formula8)
formulas1.Append(formula9)
formulas1.Append(formula10)
formulas1.Append(formula11)
formulas1.Append(formula12)Dim path1 As V.Path = New V.Path() With {.AllowGradientShape = True, .ConnectionPointType = Ovml.ConnectValues.Rectangle, .AllowExtrusion = False}
Dim lock1 As Ovml.Lock = New Ovml.Lock() With {.Extension = V.ExtensionHandlingBehaviorValues.Edit, .AspectRatio = True}shapetype1.Append(stroke1)
shapetype1.Append(formulas1)
shapetype1.Append(path1)
shapetype1.Append(lock1)Dim id As String = DateTime.Now.Ticks.ToString() ‘”_x0000_i1025”
Dim sWidth As String = String.Format(“{0:0.##}”, Convert.TwipsToPoints(widthInTwips))
Dim sHeight As String = String.Format(“{0:0.##}”, Convert.TwipsToPoints(heightInTwips))
Dim sStyle As String = “width:” + sWidth + “pt;height:” + sHeight + “pt”Dim shape1 As V.Shape = New V.Shape() With {.Id = id, .Style = sStyle, .Type = shapetypeId} ‘, .Ole = False
Dim imageData1 As V.ImageData = New V.ImageData() With {.Title = “”, .RelationshipId = imagePartEMFid}shape1.Append(imageData1)
Dim oleObject1 As Ovml.OleObject = New Ovml.OleObject() With {.Type = Ovml.OleValues.Embed, .ProgId = progID, .ShapeId = id, .DrawAspect = Ovml.OleDrawAspectValues.Content, .ObjectId = DateTime.Now.Ticks.ToString(), .Id = embeddedPartOLEid}
embeddedObject.Append(shapetype1)
embeddedObject.Append(shape1)
embeddedObject.Append(oleObject1)Dim paragraphForEmbeddedObject As Wordprocessing.Paragraph = New Wordprocessing.Paragraph()
‘Dim run1 As Run = New Run(picture)
Dim runEmbeddedObject As Run = New Run(embeddedObject)‘paragraphForEmbeddedObject.Append(run1)
paragraphForEmbeddedObject.Append(runEmbeddedObject)Return paragraphForEmbeddedObject
As a workaround/hack I can size the embedded Excelobjects via the Word objectmodel as postprocessing (if Word is present), but prever to prevent this workaround.
Kind regards,

Unfortunately, I have no experience in this area.
I presume there is some issue associated with extents or metrics, but it would take some research to figure this out.
After running your workaround/hack sizing the embedded Excel objects via the Word object model, you should get a pretty good idea of what your markup should be by looking at the markup after Word does its thing, do you not?
Best, Eric
