Shows how to extract embedded OLE objects into files.
let doc = new aw.Document(base.myDir + "OLE spreadsheet.docm");
let shape = doc.getShape(0, true);
// The OLE object in the first shape is a Microsoft Excel spreadsheet.
let oleFormat = shape.oleFormat;
expect(oleFormat.progId).toEqual("Excel.Sheet.12");
// Our object is neither auto updating nor locked from updates.
expect(oleFormat.autoUpdate).toEqual(false);
expect(oleFormat.isLocked).toEqual(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.
expect(oleFormat.suggestedExtension).toEqual(".xlsx");
// Below are two ways of saving an OLE object to a file in the local file system.
// 1 - Save it via a stream:
let writeStream = fs.createWriteStream(base.artifactsDir + "OLE spreadsheet extracted via stream" + oleFormat.suggestedExtension);
oleFormat.save(writeStream);
await finished(writeStream);
// 2 - Save it directly to a filename:
oleFormat.save(base.artifactsDir + "OLE spreadsheet saved directly" + oleFormat.suggestedExtension);
