Hi, I would like to know if anyone of you would be kind enough to tell me what is the difference between VBA application and VBA.net? All I want to know is to learn VBA to improve in writting programs in excel using VBA. Can anyone tell me which class I should take? Anywhere I look, they are teaching VBA.net, not application. Is there a big difference, or for my purpose, do I need VBA.net? I am a chemist, using spreadsheets and charts and etc. I do not care for Net using at this point. All I want to do is to automate my current excel charting and editing and trouble shooting which I think knowing VBA will be of alot of help.
