Examples

Shows how to extract embedded OLE objects into files.

Document doc = new Document(MyDir + "OLE spreadsheet.docm");
Shape shape = (Shape)doc.GetChild(NodeType.Shape, 0, true);

// The OLE object in the first shape is a Microsoft Excel spreadsheet.
OleFormat oleFormat = shape.OleFormat;

Assert.That(oleFormat.ProgId, Is.EqualTo("Excel.Sheet.12"));

// Our object is neither auto updating nor locked from updates.
Assert.That(oleFormat.AutoUpdate, Is.False);
Assert.That(oleFormat.IsLocked, Is.EqualTo(false));

// If we plan on saving the OLE object to a file in the local file system,
// we can use the "SuggestedExtension" property to determine which file extension to apply to the file.
Assert.That(oleFormat.SuggestedExtension, Is.EqualTo(".xlsx"));

// Below are two ways of saving an OLE object to a file in the local file system.
// 1 -  Save it via a stream:
using (FileStream fs = new FileStream(ArtifactsDir + "OLE spreadsheet extracted via stream" + oleFormat.SuggestedExtension, FileMode.Create))
{
    oleFormat.Save(fs);
}

// 2 -  Save it directly to a filename:
oleFormat.Save(ArtifactsDir + "OLE spreadsheet saved directly" + oleFormat.SuggestedExtension);
