< Tarinaky_>
Can anyone tell me how, in VC++ 2008 express one can have a canvas that I can paint simple geometric shapes onto?
15:56
< Tarinaky_>
Also - getting input from the mouse would be nice.
15:56
< Tarinaky_>
I'm really having difficulty finding information on what I'd have thought would be a simple thing :/

< gnolam>
WinAPI. MFC. .NET. DirectX. Any wrapper library for these. Pick one.
16:09
<@TheWatcher>
Or SDL >.>
16:10
< Tarinaky_>
I tried to use SDL because I already had experience with it.
16:10
< Tarinaky_>
Lost 2 hours trying to get it to work in VC++.
16:10
< Tarinaky_>
I didn't hate windows before today.
16:10
< Tarinaky_>
I do now.
16:10
< Tarinaky_>
>.>
16:10
<@TheWatcher>
vc++ is required?
16:10
< Tarinaky_>
If this was my box at home I'd have something by now -.-
16:10
<@TheWatcher>
Oh, uni work?
16:10
<@TheWatcher>
Bleh
16:11
< Tarinaky_>
Yeah. I'm at Uni.
16:11
< gnolam>
TheWatcher: SDL falls under the last category, "Any wrapper library for these".
16:11
<@TheWatcher>
True.
16:11
< Tarinaky_>
gnolam, I don't know windows and I can't install anything.
16:11
< Tarinaky_>
Of those which one a) is easiest and b) comes out of the box?
16:12
< Tarinaky_>
I've found -a- tutorial so far. But it says to "include the following popup menu in your application" with no explanation as to where in my program that'd go :/

16:16 * TheWatcher ums
16:16
< Tarinaky_>
It's particularly annoying given I don't have a windows box at home so it's not like I can do this at home :/
16:16
<@TheWatcher>
I am somewhat Confused, not to say Concerned.
16:17
< Tarinaky_>
I'm confused too.
16:17 * Tarinaky_ hasn't touched Windows since ~2006-ish and has never developed for Windows.
16:17
<@TheWatcher>
If this is uni work, then (call me crazy, but I do have some moderate experience with this) shouldn't you have either been taught or have access to materials explaining this stuff?
16:17 * Tarinaky_ hasn't got a -fucking- clue what he's doing.
16:17
< Tarinaky_>
TheWatcher, Not really, no.
16:18
< Tarinaky_>
I have a specification for the functions that control the servos on the prototype.
16:18
< Tarinaky_>
But that's about it.
16:18
<@TheWatcher>
Uh...huh
16:19
<@TheWatcher>
So the other students are just doing text interfaces or something?
16:20
< Tarinaky_>
The different sub-groups are doing different things.
16:20
< Tarinaky_>
The group immediately behind me ar emeasuring the spectrographic properties of bits of coloured plastic.
16:20
<@TheWatcher>
Ohgod, uni group work
16:21
<@TheWatcher>
So let me guess, you're doing all the work and the other muppets are at the pup getting ratarsed?
16:21
<@TheWatcher>
*pub
16:21
< Tarinaky_>
And I would be working on the control software for the prototype mount except the software to work on the software isn't on so I'm having to do 'something else'.
16:21
< Tarinaky_>
And no. As far as I'm aware everyone is working hard.
16:21
< Tarinaky_>
I'm the only one in my sub-group.
16:22
<@TheWatcher>
Oh..kay
16:22
< Tarinaky_>
I said the words programming and everyone ran like I had leperosy.
16:22
< gnolam>
Tarinaky: The easiest would probably be to use SDL. But of the others, pure WinAPI.
16:22
< Tarinaky_>
Or was on fire.
16:22
< Tarinaky_>
gnolam, I lost 2 hours trying to get SDL to work >.>
16:22
< Tarinaky_>
There're no packages for VC++ 2008. Only 2006 which I was under the impression was incompatible.

16:24
< gnolam>
Unfortunately, my WinAPI experience basically just consists of popping up the occasional dialog box.
16:24
< gnolam>
(And some window init code for an open source library, but that sin is well in the past)
16:25
< Tarinaky_>
Well. I'm going home in half an hour where I have root access on a linux box. I need to make up lost time - how easy will it be to set up a cross-compiler for SDL and get something that should work on a windows box?
16:25
< gnolam>
Anyway, compiling SDL shouldn't be a major problem. Getting it to work reliably on different computers, though...
16:25 * Tarinaky_ has WINE, yay >.>
16:27
< Tarinaky_>
gnolam, tried that. The project file was for VC++ 2005 which is -definately- incompatible.
16:29 * gnolam shrugs.
16:29
< gnolam>
The binaries should be compatible anyway.
16:35
< Tarinaky_>
Also: WTF is an LPCWSTR and how do I make one?
16:35
< Tarinaky_>
The documentation says it's a pointer to a wide-character string.
16:35
< Tarinaky_>
But it doesn't mention how you're supposed to construct the wide-character string it points to >.>
16:39
< Tarinaky_>
Ah. Nm. Got that.
16:40
< Tarinaky_>
Still. This is going to be a long week - I have that feeling :/
16:41
<@TheWatcher>
And I guess that Leicester are a pure windows shop? :/
16:42
< Tarinaky_>
Not strictly.
16:43
< Tarinaky_>
We have accounts on a Linux box we can connect to.
16:43
<@TheWatcher>
...
16:43
< Tarinaky_>
Problem is the problem calls for a Windows binary.
16:43
< Tarinaky_>
And I couldn't get mingw to work on here because I don't have root access >.>
16:46
< Tarinaky_>
"make: execvp: i386-mingw-g++: Permission denied"
16:46
< Tarinaky_>
And I already chmod +x the binaries :/
16:49
< Tarinaky_>
I'm going to pack up anyway.

<@McMartin>
08:35 < Tarinaky_> Also: WTF is an LPCWSTR and how do I make one?
18:59
<@McMartin>
08:35 < Tarinaky_> The documentation says it's a pointer to a wide-character string.
18:59
<@McMartin>
It's also const
18:59
<@McMartin>
Long Pointer to Constant Wide String
19:25
< Tarinaky>
Still no idea how you're supposed to create one.
19:29
< gnolam>
Create an array of wchar_ts.
19:29
< gnolam>
And pass in a pointer to it. Or pass it in as a literal.
19:29
< Tarinaky>
Cheers.
19:32
< gnolam>
To make a wide-character string literal, simply prepend 'L' to it. I.e. L"Foo" instead of "Foo".
19:32
< Tarinaky>
I don't understand.
19:33
< gnolam>
What part?
19:40
< Tarinaky>
Literals.
19:43
<@McMartin>
The physical strings.
19:43
<@McMartin>
If you're doing Windows development, most functions are actually defined twice, once for char * and once for wchar_t *
19:44
<@McMartin>
If you use the default version and wrap your string constants with _T("blah"), it'll do the right thing in each case regardless of link type
19:46 * AbuDhabi weeps tears of bubbling pitch. I was not made to be a calculator simulator.
19:56
< gnolam>
You are the operator with your pocket calculator?
19:56
< gnolam>
You are adding and subtracting?
19:56
< gnolam>
You are controlling and composing?
19:57
< gnolam>
By pressing down a special key, you play a little melody?
19:59
< AbuDhabi>
I have an exam on wednesday. It's an exam in solving linear equations by hand. We're not allowed calculators.
19:59
< AbuDhabi>
Essentially, we cannot make any mistakes, or we fail.
20:02
< gnolam>
Ye gods doing manual backups is boring.
20:09
< AbuDhabi>
I really can't brain today. If given A and b, how do I calculate X in A*X=b? A is a nxn matrix, X and b are nx1 column vectors.
20:10
< AbuDhabi>
X=(A^-1)*b?
20:13
< AbuDhabi>
Okay, that seems to work.
20:13
< AbuDhabi>

For me, most days, that makes it sometime between 12h00 and 15h00, lasting from the first bite of my sandwich to the second.

Doing something with Kalman filters?

No. Studying for exam.
