I am working on an object-oriented alternative library to C++ called the Object Oriented Template Library. It is designed to present a more abstract set of collections and primitives. A detailed description and preliminary documentation is available at http://www.cdiggins.com/ootl.html[^]. Let me know if you would be interested in seeing end up on codeproject.com once it matures somewhat.
Thanks all!

Hi Christopher
I, for one, would be very interested in seeing this library develop at CP (or any other place, for that matter). I've got a couple of questions:- Is there any draft source code we can have a look at?
- The preliminary docs are, well, sort of preliminary, so I couldn't grasp which are the intended benefits of OOTL as compared with STL (the lib is presented as an alternative to the latter.) If I'm understanding your rationale, I'd say OOTL collections work more or less like the STL with the important difference that they support interface-based polymorphism. Is this the key concept behind OOTL, or am I missing something?
Collections aside, I find the interface concept much intriguing. Reminds me of some dynamic type checking languages like Smalltalk, with some added compile-time checking in the spirit of C++. While I'd say this type of programming is not what C++ purports to support, maybe it can be useful for prototyping and some forms of RAD programming. Have you investigated how well interface programming interacts with GUI frameworks like MFC and WTL? While these frameworks are not polymorphic in the C++ sense of the word, it seems to me like commonality between different widgets (for instance, the SetWindowText/GetWindowText stuff) can be appropriately captured by suitable interfaces.

Hello Joaquín,
I, for one, would be very interested in seeing this library develop at CP (or any other place, for that matter).
I am very pleased to hear that.
I've got a couple of questions: Is there any draft source code we can have a look at?
By tommorrow morning there will be, but I will have to warn you that making interfaces and design by contract work in C++ leads to some really complicated code.
If I'm understanding your rationale, I'd say OOTL collections work more or less like the STL with the important difference that they support interface-based polymorphism. Is this the key concept behind OOTL, or am I missing something?
This is essentially correct, though I consider the most important difference to be that the OOTL collections are arranged in a proper hierarchy, and are more like the abstract data types they represent. It may seem trivial, but the fact that the OOTL collections all use a common iterator type makes working with OOTL collections much easier and less cryptic.
Collections aside, I find the interface concept much intriguing. Reminds me of some dynamic type checking languages like Smalltalk, with some added compile-time checking in the spirit of C++. While I'd say this type of programming is not what C++ purports to support, maybe it can be useful for prototyping and some forms of RAD programming.
Most definitely but the applications extend to any kind of object-oriented design.
Have you investigated how well interface programming interacts with GUI frameworks like MFC and WTL?
Not yet, but this is a direction I would very much like to explore. There are no forseeable options to using interfaces with these kinds of libraries. It would be great to design a GUI library that could be adapted to work with different C++ GUI toolkits.
While these frameworks are not polymorphic in the C++ sense of the word, it seems to me like commonality between different widgets (for instance, the SetWindowText/GetWindowText stuff) can be appropriately captured by suitable interfaces.
Definitely.
Thanks again for your interest, and I will post to this thread as more news occurs. If you wish to follow or contribute development discussions, you can easily do so at http://groups-beta.google.com/group/ootl[^].

The programmer shouldn't have to code them. You should provide classes or language constructs that can be translated by a pre-processor (much like C++ used to be translated into C in the early days; is that still the case?).
Just my two cents. ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

The OOTL documentation has been rewritten, and a first public release has been made of the code at http://www.ootl.org[^]
I am also currently working on an article for submission to codeproject.com.

I created a holiday Flash movie. Published it to html, htm & swf. I put the htm link into my signature slot in Outlook Express so I could put the movie at the end of my holiday greeting to my family.
I tested it by sending & receiving to myself through OE & Yahoo. The OE is fine with Yahoo the code is there, but nothing happens, plays, or even appears on the screen -- just the written text.
Any ideas on what code I need in the htm to cause Yahoo to play the swf when the email is opened?
I am stumbling blind in the dark on this one. I can't seem to find any references.
Thank you for any & all help.

how to import sql 2000 database to msde
|
|
|
|
|
Back up and restore!
Really, it is that easy. All you need is for your copy of EntManager to be able to see the MSDE server. Failing that you'll have to learn osql commands (I don't know any, sorry)
|

Do you mean that you want to talk to both servers at once, or just copy a database?
Normally you can use DTS for this...

What version of MSDE?
What *exactly* do you want to export from SQL2K into MSDE?
Is it a table, multiple tables, entire database, partial table?

It's done i have sucessfully imported data from SQL to MSDE.But i m having trouble packaging msde with .net framework and my .net aplication through PDW at the 3 step of msde Bootstrapper it show an error "invalid MSDE Files", even though i have put sql database files.

There are so many fabulous encrypting and hashing algorithms posted in CP , but strangely no Shred modules ?!I am sure lot of people are very much interested in knowing how data recovery is done and how various shredding methods ( Gutmann, DoD etc ) delete data beyond recovery...
Another trend with the authors about these subjects in CP seems to be write the code, write a few lines on how to implement it in your own project, and over.I mean, an inexperienced guy can only copy the authors code blindly, and use it in his project even though he doesn't have a wink of an idea as what he's doing.Won't it help if a bit more lines are devoted to technical discussions and the theory being implemented,apart from the application code?The authors can also post links to sites for further reading, this can let someone actually learn,rather then just copy.They are doing a great job no doubt  , but I am a bit too curious at times i guess 
Thanks,

Hi folks
How can I "add" wav files together so that resulting wav file will be the "sum" of them?
(VB.NET or C# please)
|

I'd like to see a nice, clean walk through where a simple class library is created, the documentation is generated with NDoc and the setup project registers the documentation.
That would be sweet.
Thanks.

i am a beginer to socket programming, i read your article i think it the best for beginers like me, i have two questions;
1. my question is how can i assign a specific ip address to server and client for example 193.125.100.10 and 193.125.100.11 for server and client respectively.
2. 2nd question is i want the application to act as server and client simultaneously, and can chat with multiple peers simultaneously.
i will be greatful for your help, and i am sure you will help beginner like me.
thanks and bye.

I'd like to see if anyone out there has any experience in catching webdav requests to IIS and redirecting them to an ASPX page for processing. IIS handles webdav requests, but only allows you webdav on a physical windows file system. I'd like to intercept the requests and present my own custom file system to the user. Anyone done anything like this?

Not exactly - have you played with MS Exchange OWA or MS Sharepoint (full or Team Services)? Exchange has its own filesystem, sharepoint has virtual fs mapped to MS SQL server.
I think you may want to read about mod_dav_fs and mod_dav_svn as code examples. These modules are dav storage/mapping/locking plugins for appache, so they do what you want, but on different platform.
Regards

I have not played with those products but I have examined them and believe that Sharepoint uses an ISAPI filter to re-route the webdav requests to and from IIS to it's virtual file system. That's basically what I wanted to do. But I suppose if we could build a webdav server with APACHE that would work equally well as long as it ran on Win2k and 2003. I don't necessarily need to run it through IIS if I ship my own web server to do this function. The only issue will be programmatically configuring it so that I can run them both on port 80 on the same box, but with different host headers.
I will check out the apache resources. Thanks for the info.
