Does anyone knows any good visual diagram library, that can help me implement faster an application like visio (but simpler of course), that the user can create entities drag them and create links between them (more than one link), and give the possibility to customize the look of each entity.
Does anyone knows anything to do this (c++)
Thanks
Consider using Qt.

I've to create an application which is made up in a tabular way, with rows and columns having cells, in a grid like format. There have to be appropriate cell-level controls as well.
Because of certain constraints, this has to be done in MFC.
I tried searching for something like Grid view/tabular view in MFC, but couldn't locate it. All I managed to get were user developed libraries on other sites, but which I cannot use because of license restrictions.
As a starting point, what should I be looking for? I've worked on Qt before, but not MFC, and am fining it difficult to locate appropriate tutorials regarding grid/tabular view.
Kindly give me a starting point, or a library name for me to start looking into.
Thanks.
Either you use something open source like the ultimate grid or CGridCtrl, or you use a library like BCGSuite. You say 'cannot use because of licence restrictions' but you don't say what you mean. CGridCtrl for example can be used in commercial and free applications. For a high-quality (i.e., with support for modern features like theming), you'll need a commercial library.
I was looking at MeVisLab and I wondered if anyone knows a good framework for making a user interface similar to the one they use. I like the designing flow with boxes and arrows thing.
What I would really like is to able to integrate with C++ using Qt, and perhaps export the graph to xml of something like that.
There is another example of the interface here:
I hope someone knows something
Qt's Graphics View is a "framework" which does a good bit of the handling for the kind of scenario you describe. It doesn't take much code to get off the ground and within striking range of what you're looking for:

I'm not aware of any open-source Qt-based programs that offer exactly what you want already written. Just noticed IBM did open source "DataExplorer", which is interesting to me...I might go take a look at that myself:

I am trying to get started with HTK, I grabbed a copy, compiled it, grabbed the book, and all went more or less fine, little troubles here and there but nothing serious.
Now after reading the book and googling quite a while, I do not see any documentation for the essential part for me: HTKLib. Everything is described into the smallest detail for all HTK tool programs (scriptable command line interface tools) but I cannot find a single example or tutorial how to actually call the lib.
Could anyone point me into a direction?
The source code for the respective tools is included, but it would be rather cumbersome to have to extract the information for a reputable library by reading the source code... I would have expected a little more documentation , but maybe I simply overlooked it?
Any help is deeply appreciated,
Tom
edit:
I was trying to use HTK for computer vision purposes, not for NLP, and for that I required that I could link against it, and call it from within my code. Thanks for your replies.
Maybe ATK is more suitable for you. Here is the explantation from the ATK site:
"ATK is an API designed to facilitate building experimental applications for HTK. It consists of a C++ layer sitting on top of the standard HTK libraries."
In addition Microsoft Research has another research tool here for training acoustic models. This includes a set visual project for HTKlib and a set of C++ HTK wrappers, but it may only include a subset of the HTK functionality and has licence restrictions.
I have not used it but use I the language modeling toolkit. I think the main intention is to use the command line tools provided. I imagine they are very flexible tools that will enable you to build and test models. Why do you want to use the code?
Also what are you trying to do?
I want to create a context menu that support multiple files.
I read through SO and understand that either you must use DDE or shell extension (something to do with creating and registering COM object). However all the sourcecodes I found are in C#.
I then decided to go with COM object. I found 1 in C++ that uses COM but it's dated 2006, so I just don't know if it's outdated. http://www.codeproject.com/KB/shell/shellextguide1.aspx
Can anyone shed me some light on this? And is there any good and new article out there covering this issue?
Or if anyone has some something similar before using DDE and IPC?
It should work fine, the underlying mechanic hasn't changed in the last 4 years.
Take a look at the comments at the bottom of the article, people are using it without problems. (There is also a link to a VS 2008 template for multiple-files)
I am trying to create some charts of data (eg http://www.amibroker.com/). Is there a C++ library that can do this without a lot of extra work? I'm thinking Qt or wxWindows would have something like it, but it wasn't immediately obvious.
Thanks!
FLTK is a light and portable C++ toolkit for GUI. There's a chart class. Sample.
Qwt does at least some of the things you are trying to achieve (basic plots, bar charts and so on), and integrates well with Qt.
I think you need to pick your GUI framework first, then find a charting control for the given framework, since that affects what charting controls you could feasibly use. For example, must this be portable?
For the project I'm working on (a large MFC application) we use Cedric Moonen's ChartCtrl. We've had a pretty good experience with it so far.
I've done some graph plotting with gnuplot lately, which is quite powerful. Although I think it is Linux only, which may or may not be a problem.
Also, believe it or not, some amazing things can be done with LaTeX. I've used the tkz (tikz) library to produce some awesome graphs.
Both solutions plot to a file which you can include in your interface.
They aren't C++ libraries but you can easily create the datafiles and call the necessary programs from within your C++ program (Being creative with system() and possible some shell scripts).
