Also speaking of the first issue: the code which reproduces the issue in
the WriterDemo.cs looks like:
// Create a cursor object
XTextCursor cursor = simpleText.createTextCursor();
cursor.query<XPropertySet>().setPropertyValue("CharWeight", new
Any(((float)200)));
cursor.query<XPropertySet>().setPropertyValue("CharEscapement", new
Any((Int16)0));
*cursor.query<XPropertySet>().setPropertyValue("CharEscapementHeight", new
Any((Byte)100));*
// Inserting some Text
text.insertString(cursor, "The first line in the newly created text
document.\n", false);
The 'Object reference not set to an instance of an object.' occurs on
the cursor.query<XPropertySet>().setPropertyValue("CharEscapementHeight",
new Any((Byte)100)); line.
