    <p>I wrote an MS JScript utility (for use in SmartBear's TestComplete) that exports images that are embedded in a Word document to PNG files on disk. When I run this utility on Win7, with Office 2010, everything works fine. But when I run it on Win8 with Office 2013, I get an "illegal value" error when passing the PpShapeFormat filter to the Export method. </p> <p>Here's the relevant portion of my script:</p> <pre><code>//get the list of shapes from the word doc, and how many there are var iShapeList = DocObj.InlineShapes; //DocObj is created elsewhere var iShapeTotal = iShapeList.count; //create a powerpoint object and instantiate a presentation var pptApp = Sys.OleObject("PowerPoint.Application"); //open PowerPoint var pptDoc = pptApp.Presentations.Add(); //create a new blank document var pptDocSlide = pptDoc.Slides.Add(1, 12); //12 = ppLayoutBlank var pptShapeFmt = pptApp.PpShapeFormat; //format filter object //loop through the Word document shapes, copy each one, paste it to the Ppt slide, //export the image out of the slide, and then delete it for(var iShapeNo = 1; iShapeNo &lt;= iShapeTotal; iShapeNo++) { var iShape = iShapeList(iShapeNo); //get a shape iShape.ScaleHeight = hScale; //set the shape height and width iShape.ScaleWidth = wScale; iShape.Range.Copy();//copy the shape to the clipboard try { with (pptDocSlide.Shapes.Paste(1)) //PpViewType 1 = Paste into Slide View { //Export the image pasted into the slide, to the extract path, then delete the slide. Export(ExtractPath + "\\" + IntToStr(iShapeNo) + ".png", pptShapeFmt); //2 = ppShapeFormatPNG Delete(); ++successTally; //one more in the WIN column! } } catch(exception) { //does a bunch of cleanup } } </code></pre> <p>Researching the PpShapeFormat, I found this <a href="http://msdn.microsoft.com/en-us/library/microsoft.office.interop.powerpoint.ppshapeformat%28v=office.14%29.aspx" rel="nofollow">Enumeration</a> reference. But I'm having trouble finding any doc on changes between 2010 and 2013, and no good examples of how to use it properly. </p> <p>Does anyone have any idea what's going on here?</p>

    2. CO@Helen - The Export method is implemented on the Powerpoint Shape object, which is part of Microsoft's Office Interop library. You can find documentation for the method here: http://msdn.microsoft.com/en-us/library/microsoft.office.interop.powerpoint.shape.export(v=office.14).aspx

    3. CONow that I think about it, I wonder if in 2013, they've started requiring the remaining arguments. (ScaleWidth, ScaleHeight, and ExportMode, all of which I assumed were optional, since the method works fine in 2010).

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
