The <F1> key is a good place to start. (That actually depends a little on Access version.)
It might seem strange but a few years ago someone said to me that they had been using VBA for three years and did not know about the <F1> key. I think that strange because for the first six years of VBA I didn’t use anything else.
It is surprising how many questions posted on this and other sites could have been answered just by using the built in help.
Another thing I would add here. A lot of what we may read on the internet is simply recycled internet information. The recycling goes round and round, site to site, gaining bulk, but few people seem to question things. By all means read everything you can but, by the same token, question everything you can.
An example of question things is in one of links in post #4. In the first screen shot of writing code there is no Option Explicit and the Form name is hard coded rather than using Me.
If you see something interesting, test it. Create a new database and write the code. If it doesn’t work then fix that small part. If it does work then make it work better. If you still think it looks like junk then ask a question about how to write it better.
Read, write, test and question.
Chris.
