Pointer to String chars - Everett style

Posted Monday, December 22, 2003 2:51 PM by arich
Garrett asked: If the source text is in a CLR String, and we want to pass(even read-only) to unmanaged code, it appears that there is no way to get a pointer to the String's buffer directly. We have to use the marshalling stuff to get it there, which Read More...

The native heap/managed heap barrier

Posted Monday, December 22, 2003 11:15 AM by arich
Garrett asks: You mentioned: class A{}; array ^ arr = gcnew array (10);. Are you saying that whidbey will support this? What is it doing to the native pointer? Boxing? Managed array of native pointers to native objects? This didn't work in Everett, but Read More...

Clarifications on the array template, and some about the CLR namespaces

Posted Friday, December 19, 2003 11:18 AM by arich
Garrett returns with some observations: Damn Cool. My only reservation is that it doens't *resemble* a native array, but that's ok too :) In some ways that is far better than the alternative. I was never quite thrilled about the cryptic nature of managed Read More...

Why you ought not pre-jit, and why it sometimes makes sense.

Posted Friday, December 19, 2003 10:51 AM by arich
So, Raj asks: Thanks for the explanation but what is the deal with the IL and JIT. Why not just prejit the code? Why not pre-jit the code? Class, you didn't do the required reading . :) Actually, there are a couple of optimization reasons why you don't Read More...

Dave strikes again, a basic description of how .NET works.

Posted Thursday, December 18, 2003 7:30 PM by arich
Dave asks: i have tried some UI examples in the book, but it was quite slow. when I execute the program, it takes 1.5-2seconds to see the window on the screen, on the other hand plain win32 api creates window before 1st second. doesn't .net generate native Read More...

The array template

Posted Thursday, December 18, 2003 6:14 PM by arich
Some background. In Managed Extensions, the CLI Array was exposed using the keyword __gc [] . If you wanted a CLI array of, say, ten int s named arr , you did: int arr __gc [] = new int __gc [10]; . Then, access into the array worked much like native Read More...

VC++ .NET Examples, a tiny Visual Studio timeline, how to participate in the Whidbey Beta

Posted Wednesday, December 17, 2003 11:36 AM by arich
Reader Dave commented: back to lack of visual c++ .net examples. I saw that there are lots of c# examples, this is good because C# is a new language and if i am correct, it is built for .net. there are vb.net examples, too, but there is not a visual c++ Read More...

A little Q&A

Posted Tuesday, December 16, 2003 11:23 AM by arich
Reader Dave asks: I am using Visual Studio 7.0 (2002?). I turn on my computer in the morning, and run it until midnight and my visual studio is always open. however, it consumes 60-150MB Virtual memory, specifically when i use VisualPerl (I usually use Read More...

C++/CLI operators

Posted Friday, December 12, 2003 11:44 AM by arich
A bit of background. You may recall CLI operators in Managed Extensions: op_Equality, op_Addition, ... so on and so forth. To be sure, not the friendliest set of operators ever, as you had to remember what their names were in order to overload them. How Read More...

Mono, more on cross-platform

Posted Thursday, December 11, 2003 11:39 AM by arich
Mono (very different from mono ), is, at its core, an implementation of the Common Language Specification - which we purposefully made public domain through ECMA . Mono is pretty cool, too, and I'm personally glad to see it. They even praise the standard Read More...

C++ feature "lag," native types on the GC Heap, a plug for some software I like

Posted Thursday, December 11, 2003 10:48 AM by arich
Garrett points out: I *am* a tad sad that C++ tends to lag a generation behind C# on features in .NET. I realize that's likely due to the larger effort required, with less resources than C#, and it seems that C++ is less ...sexy... than C#, but it's still Read More...

Will .NET be available for non-Windows platforms?

Posted Wednesday, December 10, 2003 3:53 PM by arich
I thought this deserved a post, and not be buried in a comment. Dave asks: Wow! it seems you are empowering c++ for CLR. will .net be available for non-windows platforms? IT ALREADY IS! Being Microsoft, you'd think .NET would be a Windows-only innovation. Read More...

More questions, more clarifications.

Posted Wednesday, December 10, 2003 2:19 PM by arich
Garrett asked some further questions that were also good. Good enough, in fact, that I didn't know the answers. So I went down the hall and asked Brandon . I'll paraphrase what Brandon told me here. 1. What about partial types? What are partial types? Read More...

Whidbey and Managed Extensions, clarifications.

Posted Monday, December 08, 2003 1:20 PM by arich
Garrett Serack made some comments on my last blog entry that I thought were interesting enough to share with everyone. He asks: And how about forward source-level compatability between .net 1.1 and whidbey? Is the current batch of Managed C++ gonna work Read More...

The powers-that-be in charge of the GotDotNet have decided to discontinue the blogs on this site. We're being asked to propogate our blogs over to weblogs that are provided by asp.net. Believe me, if I had my choice, I would stick with BlogX and GotDotNet, Read More...
