We form coded that will open and display a doc,docx,txt or PDF file within vb6 form. We are open to approaches but have assumed will be OLE container. BUT we are open to any other suggestions. We need to be able to highlight user defined text in the document as well. eg, after opening documents highlight all instances of words "london, banking, singapore" attached is zip file with vb6 project , single form and 2 buttons only to programme. Open (allows user to select file) , highlight (highlights selected text) next unit will be parsing , this unit just open and highlight. ## Deliverables attached file has vb project form to be coded. Just 2 buttons to code.
