What Every Comptent Excel VBA Programmer Must Know...

1.  I'm looking for a list of features, commands, statements, functions mistakes to avoid, etc. that every competent VBA programmer must know.
2.  Please also list how well these things should be known. (i.e. a general familiarity, working knowledge, or "must know this inside and out")

Hi,

Are you writing a set of questions for a technical interview for a prospective candidate?

If so, we have Previously Asked Question threads on such topics.

[PS. Where do I apply? ;)]

BFN,

Thanks to all for the responses!

Message to Fanpages.
It's just for my knowledge. Not for a candidate or a technical interview.

I've been using VBA for about a year and I STILL get slapped in the head, and face with some problem someone asks me to solve that I have absolutely no clue about!!!!!  So, I thought "I must be missing some knowledge that I'm not able to figure things out on my own.
That's why I posted the question.  I keep getting perplexed.

Being part of the community here should demonstrate the various ways any issue can be addressed.

There is always something new to learn & at least one new approach to a problem you may have resolved previously.

If you are not already doing so, perhaps you could look at some of the newly created questions to see how you would offer advice &/or a solution.

Then, sit back & see what alternatives are offered.

That, arguably, is a way to learn more & I am sure you will not be disappointed!

Good luck.
