"Draw Partner!" - My first mouse drawing app

[Corey]

This is just a simple example I made from a "learning VC++" book. It's nothing at all, yet is jolly good fun though also.

I like it! It's like drawing in Flash but looks more like pre-WinXP icons. (not as, ahem, flashy)



How many lines of code Corey?

Accomplishement is satisfying!

[Corey]

Well the application itself is lots of code, i.e. the C++ part but of course that is created by VC++, all I did was add a few lines of code inside a function. It's nothing major, very little code. But to actually do anything useful with it, i.e. create a screen drawing or annotation plug-in for AutoPlay Media Studio is what's tricky.

Slowly but surely I creep up on it though and then one day, just when you least expect it, WHAMMO! I write a plug-in...

I'm just chipping away at it, I tried to approach it from the C++ end before and that crapped out, so now I'm just trying to learn a tiny bit of MFC each day and see where that leads. I have too many ideas for AMS plug-ins. Design time ones too which deal with visual effects and stuff like that, more like Photoshop plug-ins really, but for AMS. Anyhow I ain't making no promises, and I ain't not making no promises. Because everytime I do that with C++ someone end up with a stick in the eye. So I'm just taking it day by day.

Anyhow FWIW the second version took a few more lines of code than the first. It's not a practical drawing app, you could do a zillion times better using the Flash drawing API. But for some reason I enjoy sketching in version 1 with my tablet. It has a nice pointilist look and I like the way the dots get sparser as you sketch faster. I actually managed to do a couple decent sketches in it I forgot to take screencaps though. Next time.

P.S. The icon is just the default MFC app icon.

[Intrigued]

Ah, thanks for the walk-thru!

I did buy a MFC based book earlier last year. However, I decided to work on the plugins for AMS (ans now SF 7!) and Flash MX 2004 it's ActionScripting.

Though, I am sure to come back to such... hopefully right as you release your first "Create Your Own Plugin" C.B.T. CD!

[Corey]

I wouldn't learn VC++ if it weren't for my gig at IR and my realizing that it's not an option if I wish to be completely relevant.

AMS + Flash will get you more audience approval in a faster time than hand coding any apps will. Here's the thing, people notice what they see, and rapid development of highly stylized materials is not what VC++ is for. That's what AMS and Flash are for.

I'll keep you posted as I learn stuff but suffice to say that unless you are looking to become a software manufacturer, you will get much more benefit out of learning Flash than VC++. Flash skills are timeless, and for my money I can still get more "real world" stuff done in quicker time, with better visual results, using Flash+AMS than I can using VC++. Then again I like Michael MacDonald's singing, so I don't know how much stock you want to put in my opinion.

Good work, Corey. The think is that once you get this GDI drawing stuff down, then making plugins is relatively easy. And, every plugin that we have made so far uses MFC, so the MFC is by no means a waste.

The most useful classes in MFC in my opinion are not the windowing classes but rather the data classes:

CString, CObject, CArchive, CFile, CObList, etc.

Of course, a good understanding of CWnd is useful too. I found that with C++/MFC it takes a bunch of hacking away at it and then one day - whammo, you start to get it.

If you want to start working on a plugin right away, do this:

1. Get and install the AMS 5.0 SDK
2. Make a copy of the AutoPlay Media Studio 5.0 SDK\Samples\Shape folder to somewhere else on your HD.
3. Open the copied shape project.
4. Find the function CShapeObject :: DrawShape in ShapeObject.cpp.
5. In that function you can do any kind of drawing that you want - just use the hDC that is passed in.

More tips:

- To change the name of the object, look in Shape.cpp
- To change the name of the plugin file that is generated, go to Project > Settings and select the Link tab. There you can change the "output file name".

Anyone with even a bit of C or C++ windows API programming experience can use the above to get started on making your own plugins. After you get started with the above, look up the functions that are used in the SDK reference and keep learning. It really isn't that bad. Give it 2 hours without giving up and you'll get it!

[Corey]

Oh I've given it 2 hours sir, believe me, that and maaaaaaany more. Sir. Anyhow as to you're comment about "whammo", I KNEW IT! Just like I said, I'll be just whistling along main street without a clue in the world and then suddenlyyyyyy WHAMMO!!! and I'm chunking out the plug-ins like some kind of insane plug-in chunker.

Can hardly wait. Fact is I don't understand a thing yet though, I'm just typing what's in the book.

Thanks for the tips Brett.

[Derek]

I nearly wrote this once but deleted it incase i phrased it badly and upset someone. And here i am again deciding to post it anyway.

I am touched! I think its just great that people like Brett [who i am sure is a God to most of us on here] has time in his day to chip in with stuff like that to help others and its like "just who he is". Not at all condescending and always a nice tone to his voice - as it were.

I salute you, Brett.

[Corey]

If there really is a Brett, then why do bad things happen to good people?

[Intrigued]

Sooooo you're telling me there is a channnnce! (in so many words)

(Dumb and Dumber)

[Worm]

Thanks Corey!

Hot coffee in my sinuses, not a good thing!

I'm with you. I've put in several hours pouring through the sample plugins, and some of it confuses me.

If there really is a Brett, then why do bad things happen to good people?

[Intrigued]

bump time.

[Corey]

Still been plugging away at this but spare time has been scanty of late. Nonetheless I've worked through the first bit of this book. Seeing how Worm developed his last plug-in really woke me up to some new possibilities.

[Intrigued]

Sounds good!

I was also looking at what Brett had shared with us in this thread. A little insight I thought might help as well.

Hi guys,

My team had been developing our 1st animation project on FLASH for the pass 3 months. The final product is a CD-ROM for slow learners and elementary pupils. Our client is a tuition school.

Now when it comes to COMPILING those animations into full-fledge learning applications, the logical software is definitely DIRECTOR. Well this is what the market FIRMLY believes.

For a small 3-men team on a shoe-string budget and wants to use only LICENSED software, DIRECTOR is sooooooooo expensive for us. And I need expert Director users too ( again very expensive ) . AND the process to compile takes a lot of time ( another high cost ).

So I opted to completely use AM5 Pro to compile all several hundred FLASH movies into a full-blown learning application.

The UNUSUAL part is, I need no EXPERTS to use AM5. The funny part is, I did the compilation myself and I'm not even a TECHIE !! I did the compilation in 2 days flat...

Said to myself, " Woopeedoo.. What an achievement !!! ". So, got myself a big bucket of VANILLA ICE-CREAM to celebrate. hehehe. Lemme see .... Maybe I should start learning how to use the PLUGINS in AM5 Pro.

Bottom-line ............. My client was very satisfied with the CD-ROM and now wants us to develop more products.
