I am using Syncfusion Enterprise Edition to draw flow charts and process documents with PDF conversions. I have all the components I need but best of all is the Incident Support system which provides me with first class and quick replies to my programming issues. A first class facility which I find invaluable in this age of ever changing complex programming environments - particularly since documentation for both operating systems and development tools becomes ever more complex and difficult to navigate around and find the answer to a question.
