function InsertTextFromFileW(FileName):Boolean;

function InsertOEMTextFromFile(FileName):Boolean;

These methods insert one text item (string must not contain line break, page break and tab characters) with the specified tag:

function InsertStringTag(s, Tag): Boolean;

These methods insert one item of the specified type (parameters are similar to parameters of Add*** methods):

function InsertControl(Name, ctrl, VAlign): Boolean;

function InsertPicture(Name, gr, VAlign): Boolean;
