what is the best procedure to increase advance level SAS programming skill when there is no such requirement to use those concepts. Most of the time I complete my task using basic SAS concepts like set function, merge function or some other basic function. What is your suggestion if one wants to increase the programming capabilities.
I'm not going to venture a single 'best' option, but here are a few ideas:
I haven't gone down this route myself, but you could look into studying for the SAS certifications to broaden your SAS knowledge.
If you don't already know any SQL, that's something that's probably worth learning, as it's more transferable than most other SAS-related knowledge.
If you find yourself writing lots of very similar bits of code, learn how to use arrays and write macros (and when not to write macros).
If your code is taking a long time to run, read up on optimisation techniques and see if you can find faster ways of doing the same things. E.g. hash objects, indexes and parallel processing.

Currently I have n suppliers web service which gives me search result for particular product. I am creating n threads myself and merging the final results returned by supplier. I have just come to know about PLINQ. I want to know if it would help the performance. If yes, how.
Better? Depends on what that means for you. PLINQ is definitely cleaner and more maintainable code for a lot of use cases. On the performance side depends on what you compare it against.
In your case if you are creating n threads by hand i would say you might be slower because PLINQ will use the threadpool and avoid some thread creation overhead.

It's been a really long time since I worked with UML Diagrams.
I started working with UML Use Cases again, for a real world project. I would like to ask some questions.
How should I approach writing use cases?
I believe the tasks that leads to a "Major/Bigger" task should not be considered as use cases by themselves. Am I right?
Okay, what if I have a task like View tutorial and it has Comment on Tutorial, Favourite Tutorial, etc. Should these be separate use case, Extending View Tutorial? If yes, but, aren't they small features, why we should include them?
I'm mixing some stuff here, I hope someone could enlighten me .
Thanks!
Read Alistair Cockburn's Effective Use Cases book (see it on Amazon: 1). He does an excellent job of explaining practical use of use cases in a structured and effective way.

I am wondering how you would code an image vectorization program, al la vectormagic.com? Where would you even begin and would it be possible to create in any web based programming languages?
Behind vectorization programs are complex algorithms (for basic outline look on quite nice paper depixelizing pixel art by guys at Microsoft).
Anyway, it's possible to write almost in any language, that can process images, but those complex algorithms are pretty system resources expensive. So web based languages are quite inappropriate for that type of task.

We have to train the client professionals on the source code for an application we developed. What shall I include in their training plan for source code? Any help would be really appreciated.

This may help:
What are the core elements to include in Support Documentation?
1.) If possible show them various changes/revisions the code has gone through, then that will help them to understand the code design at some higher level. (That function needs to be modified for what feature?)
2.) Extract some function Call-Graph/Function-flow diagram using some tool and let them get familiar with that.
3.) The test setup for the application should be explained to them.
4.) High level Design & Low level design document
-AD
You could highlight the important design decisions. So they understand why you have chosen which solution.

VBA solutions can vary widely in size.
I would like to add user help documentation to all solutions but the level of effort to create and deploy the help needs to match the size of the solution.
You should check the VBA version of MZ-Tools. It is an add-in for VBA that can automatically generate documentation from your code (function name, parameters, comments, subject, etc.). You can also use it to automatically generate line numbers, onError labels, etc. More on the automatic documenting feature can be found here.
It is free, easy, and very efficient. Once you notice how much you save time by using it, please do like me: donate.
You may wish to consider HTML Help. It allows you to produce help files that are similar to standard Microsoft help. It is not particularly difficult to use, for the most part.
