The ActiveDocument Object's Properties

The ActiveDocument Object is very useful in manipulating the active document, i.e. the document currently visible in the editing window. We describe its properties and methods in this and next few pages of the column. Here are its properties:

Returns a true value if recent changes can be undone.

Returns a true value if recent changes can be re-done.

Returns the file name of the active document.

Gets or sets the line at the specified index. For example, the JavaScript line app.ActiveDocument.Lines(1) gets the contents of the active document's second line. The following code sets this line to "Hello There":

app.ActiveDocument.Lines(1) = "Hello There";

Returns the number of lines in the active document.

Returns a true value if the active document has been modified since it was last saved to disk.

Returns a true value if the active document is read-only.
