15. Locate the first character

Private void gotoFirstCharacter ()

}

21. Obtain row, column, and page information

Public string WordGetRCP ()

Object a = selection. get_Information (Word. WdInformation. wdFirstCharacterLineNumber );

Object B = selection. get_Information (Word. WdInformation. wdFirstCharacterColumnNumber );
