I hope this helps people start to understand joins.
G Challenge I
Ok, my friend is trying to learn Excel VBA and get into RAD development. I am going to set a number of challenges which I am going to call a ‘G Challenge’ 😛
So the first. Take a string in the format :
20101124_170615_dd20101124_EOD.g
where the format is :
yyyymmdd_hhmmss_ddyyyymmdd_EOD.g
In VBA I would like 2 things.
- The string back in the format dd-mmm-yy hh:mm
- An actual date serial
Example above would go to
- 24-Nov-2010 17:06:15
- 40506.7126736111
Go! I would use 2 seperate functions to start off with.
Answers will be forthcoming in a post G Answer I
Excel VBA Interview Questions (aka Things every *good* Excel VBA developer should know)
I thought that I would compile a list of things that *I* think every good Excel developer should know. I don’t mean techniques in particular, just things that people who work with Excel VBA intensely each day should know.
Edit: I think a lot of people will be searching for Excel VBA Interview questions and answers so I have renamed the post and changed the format slightly. I will include all the answers on a separate post so people can try these for themselves and use it to check, or just go there immediately and cheat ;-P
I’ll illustrate : Alt+F11. If you don’t use this, or don’t know when asked what it does, I would say you know Jack about VBA. This is only my own opinion, but a lot of these things do come up as interview questions as they are quite esoteric and won’t really be something a pretender would, or come to think about it, could Google for when cramming for the interview.
I’ll start simple and group things up so they should all make sense.
Excel Interview Questions
Easy
- What does Shift+D do in this case?
- What does Ctrl+D do in this case?
- What will happen if I pull down on the corner using the plus symbol making the 1×3 cell deep selection grow to 1×10?
Back to basics. Excel (VBA) Macros 101
I have a friend who is just starting out in the professional Excel world. I thought it would be a good opportunity to write about my advice on starting out with VBA Macros from the very beginning and post it here.
My first advice would be to have a good play with the Macro recorder. Continue reading “Back to basics. Excel (VBA) Macros 101”
