Hi We are using Aspose words in java.
Shape watermark = new Shape(doc, ShapeType.TEXT_PLAIN_TEXT);
Could you please guide us how can we lock a shape object from being deleted by user?

@vgcnerella2019,

I think, you can define different Editable Ranges in your document to meet this requirement. The following sample code demonstrates how you can protect the whole document and then define a few Editable Range scopes. You can incorporate the same functionality in your project. Hope, this helps.

Document doc = new Document();
doc.removeAllChildren();

Section section = new Section(doc);
doc.appendChild(section);

Body body = new Body(doc);
section.appendChild(body);

Paragraph para = new Paragraph(doc);
body.appendChild(para);

Run run = new Run(doc);
run.setText("Hello ");
run.getFont().setColor(Color.RED);
para.appendChild(run);

Run run2 = new Run(doc);
run2.setText("World!");
para.appendChild(run2);

doc.protect(ProtectionType.READ_ONLY);

DocumentBuilder builder = new DocumentBuilder(doc);

EditableRangeStart start = builder.startEditableRange();
EditableRangeEnd end = builder.endEditableRange();

run2.getParentNode().insertBefore(start, run2);
run2.getParentNode().insertAfter(end, run2);

doc.save("E:\\temp\\awjava-20.3.docx");

I suppose, the watermark shape resides in header/footer story of your Word document. You can protect the whole document and define editable ranges for Body/Main Story content.

Any settings or SaveOptions need to be set ?
Any help is much appreciated.

Also another question, how can we identify the Run node either with id or name to edit for future purpose?

@vgcnerella2019,

It is great that you were able to resolve this issue on your end.

You can bookmark Run nodes and later access them using Bookmark’s name. e.g.

Document doc = new Document("E:\\Temp\\in.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
builder.startBookmark("name");
builder.write("this is a Run node");
builder.endBookmark("name");
doc.save("E:\\temp\\awjava-20.3.docx");
