Re: Exposing static libraries to .NET using C++/CLI

francois_oligny — Sat, 05 May 2012 21:21:43 -0000

This is exactly what I'm trying to achieve. What does your .h for the static lib looks like? Here it always fails with "unresolved token ... public int __thiscall MyClass::MyFunc()..." where MyClass::MyFunc is in the unmanaged .lib

Re: WinDbg !locks command broken

The same parameter can be used in kernel memory dumps too. But double checking ERESOURCE locks (!locks), kernel threads (!stacks) and DPC queues (!dpcs) manually is highly recomended.

Well, thanks for the calm and considered comment. Some people don't seem to realise that that's much more likely to get a response.

I'm trying to find the time to upload something useful, but it's proving a bit difficult. I don't just want to share something that I've hacked together, but instead something that's actually useful to other people.

Anyway, hopefully I'll be able to upload a sample xcode project sometime in the next week or so.

Thanks for reading.

Ian, Hi again.

I understand you have no obligation in providing anything that is requested here in the blog. But common curtesy indicates that you at least respond something like this: "Sorry folks, I know you are all asking me for the source/XCode project that I'm talking about here in this post, but I'm not able to share it".

That way, we won't keep our hopes up, and you won't be annoyed by spam-like comments, all requesting the same thing.

Thank You.
Claudia

Hey Voyce. I guess I'll add to the list of previous requests. It would be great if you could share a sample XCode project, to actually look at how you have set up things for iOS development with Bullet. Most Mac newcomers are having great issues setting things up for iOS development.

Thanks for sharing your info.
Claudia.

Awesome tutorial!! thank you for not posting the code heheheh this way I had to think about the code and what it is doing, instead of just copying and pasting n__n

Re: Beginning F#: Positive Discrimination

I keep thinking... didn't Pascal have this in the 70s? Oh yeah... "variant records." Original Pascal didn't have objects, hence the connection between the variant record's tag and code had to be made by the programmer typically with a Case statement. Current Pascals like freePascal have objects and provide a "dispatch" for variants.

LAA does not require any platform-specific code though - it just requires all the code in your application to work well with pointer MSB of 1. Most code handles this well - so you get (something close to) +2 Gb of address space on a 64-bit OS for little effort.

Luis Palacios — Sun, 04 Mar 2012 14:37:11 -0000

Hellow Voyce, very interesting article. Could you plea share the source of this project?. I'm starting from zero with OpenGL (got some experience on core animation and bullet physics) and would love to learn from your program.

Thanks in advance,
Luis

Re: Beginning F#: Records

Ian Voyce — Sun, 04 Mar 2012 08:06:31 -0000

Nope, it's a function taking a record "r" as the argument and returning a new record based on that but with a different value for the "foo" field.
Maybe it would've been clearer if I'd been more verbose and called the arg "existingRecord".

Re: Beginning F#: Records

Richard — Sun, 04 Mar 2012 04:24:26 -0000

Typo?

> let newMyRecord r = { r with foo = r.foo + 1 }

I don't think you wanted the first "r" there:

let newMyRecord = { r with foo = r.foo + 1 }

(See F# reference: http://msdn.microsoft.com/en-u... under "Creating Records by Using Record Expressions")

Re: .NET DLLs Loaded Twice

Ian Voyce — Wed, 29 Feb 2012 13:00:04 -0000

Yeah, I was thinking of a "vanilla" 32bit process, just run as-is. If you want to make the app aware of the platform, there are a few options, AWE, PAE etc.

Re: .NET DLLs Loaded Twice

Brian — Wed, 29 Feb 2012 11:04:06 -0000

To be fair a large address aware 32 bit application will get the entire 4 gb address space on 64 bit Windows. That's a significant improvement over running the same process on 32 bit.

Hi Ian,thanks for the post..it's really useful but I had some problem trying to create the full animation. Can you provide the project, please?

I'm completely new to OpenGL and it is surprising to me that when I go looking for specific beginner-level information about how to use OpenGL ES on the iPhone, I can hardly find anything..

Re: Tax Avoidance 2.0

Ian Voyce — Fri, 06 Jan 2012 17:02:09 -0000

Thanks for the positive comments. I had some doubts about posting it at all, but did so partly because I was surprised to see how little it's being discussed elsewhere.

It's certainly worrying that we seem to let tech companies get away with things for which others are (rightly) berated. I guess their PR depts are doing as good a job as their accountants.

Re: Tax Avoidance 2.0

Matt Hanson — Fri, 06 Jan 2012 10:29:12 -0000

The only bad thing about tax avoidance is that the corporations have to waste so much effort to do it. The tax rate on corporate profits should be 0%.

Corporations can't actually be taxed anyway. Only customers, shareholders and employees can be taxed through higher prices, lower dividends, and lower wages.

If corporations are locating themselves in Ireland solely because of favorable tax laws, the Irish people benefit from economic opportunities they wouldn't otherwise have, and the Irish government gets revenue (personal income tax, VAT etc.) it wouldn't otherwise get.

Don Syme — Fri, 06 Jan 2012 09:07:55 -0000

Awesome article Ian. This is a hugely serious issue, and it is great to see technically-minded people finally picking up on it. High-tech advances are permitting the "new-economy" to also be an erosion of the tax base.

(same discalimer: solely my opinion, and not those of my employer or anyone else)

Well, I understood finally ^) Initially I thought that matrix should be MVP, but after looking in bullet source I understood - it should be viewProjection. Now I get nice debug picture. Thanks for article

Re: Creating a physics-based OpenGL iOS app

Austimenko — Thu, 29 Dec 2011 21:31:12 -0000

Thanks. Very useful. But one moment for me is still unclear - how to set up projection matrix here? No btTransform passed in drawLine method...

Re: Dumping Excel XLL add-in calls

Web Design — Tue, 13 Dec 2011 06:28:07 -0000

Thats not possible in E2007, unless you are happy for your add-ins UI to be dumped in the badd ladds corner. Of course I guess ... An xll is just a dll with some registration info excel can use to call it directly from a cell.

Any word on the code - I would like to use something similar.
