I am looking for Best XML parser with support for XSD and Namespace along with SOAP Support. Looking for small footprint(ideally upto 500kB). I came across gSOAP, but not sure if Standard Open Source Edition of gSOAP supports all the features I am looking for.
Any help if much appreciated.
I think it is a good question.
First: if you use xml/soap/wsdl based web services, you have probably a really highlevel project, and thus even the c++ isn't really sure an optimal choice. I think it is very unlinkely, if you want to develop a real, working software in C, which makes soap services. IMHO you could think about java.
Second: xml and soap/wsdl are two different things, although soap uses xml for communication and the interface description (wsdl) is xml, too.
For xml handling, I suggest you could use libxml++ .
For SOAP, there is more library, but most of them isn't enough good for me to name them. Try each after the other, and sometimes you will have luck. :-)
Both libs have small footprint - they are relative complex, but don't need a legion of another libraries.

I searched the web, and found cgicc, rudeserver and Wt etc., but none of them suit my needs. I want a library that can parse all the request data to a get,post,cookie and file array, just like php does.
Cgicc etc use formentry to get form data, but it's way too difficult to use.
Wt use the widgets to develop, which I think is not very comfortable.
I used to use PHP for web programming, but when I know that C++ is amazingly faster than php, I decide to use C++ instead.
Any suggestions? thanks in advance.
I don't understand why Wt don't fit. (you could use Wt without its "widgets", just for the HTTP aspect).
You could make a FastCGI application (it would fit nicely into many existing web servers).
You could also embed an HTTP server inside your C++ application, using some HTTP server library like libonion, libmicrohttpd or the one inside poco
BTW, there are better alternatives to PHP like Opa, ocsigen, kayalang (without requiring C++).

I have tried Umbrello and ArgoUML; and both are unable to generate code from an existing c++ codebase. Though they have limited capabilities in these areas, they both fail spectacularly importing a file with std, boost, SDL and local includes. Is there anything in the FOSS world that will model reasonably complex c++ code. The UML part is optional, generating coherent and accurate visualizations of the code is what matters.
Note: Tools like gprof2dot as well as doxygen can process the source, but their output is so complex as to be equivalently difficult to grasp as the original code.
Note2: Since one cannot ask about tools on SO anymore, let me rephrase the question like this:
How, given a large, old, complex and crufty c++ code base, can one quickly and efficiently perform major refactorings. By major, I mean things like:
extracting entire structs/enums/classes from an existing source/header pair into their own files
adding/deleting namespaces
changing function signatures
etc.
Some things are approachable with grep and sed; however, discovering and managing include dependencies can be overwhelming. I'm currently stuck with the "change-and-fix" method -- try refactoring something and iteratively build and fix errors as the compiler point them out. For widely used objects, this is slow. What is the proper approach?
I used Doxygen for this on a couple of projects.
It wasn't great but it was better than starting from scratch.

I am trying to create web gui for my c++ application can any one recommend any good C++ library.I had a look at http://www.webtoolkit.eu/wt . But i am not sure that is the only solution . Is connecting with python is a good solution?
There are many other technologies more recommended for web applications, like php,asp.net, Java EE where there are many resources talking about them, and a lot of libraries exist for such technologies. So even if your backend is in C++ you can develop the front end with another techno, it will be more easy than trying to develop it with C++.
You can make use of http://www.treefrogframework.org/ as well.
In case your server is Windows based, another solution is expose your C++ application via REST with Casablanca, http://msdn.microsoft.com/en-us/devlabs/casablanca. Then provide the UI with a JavaScript framework.
Otherwise I would suggest using a language that makes it easier to bind with C++ for server development, like D (you can then use http://vibed.org/ for the web part).
Using Python will require you to use something like SWIG to be able to access the code. It all depends on how much you need to expose from the C++ side.

I'm looking at MeVisLab's interface for generating views of data and I find that that way of viewing control structures is extremely intuitive.
It is especially the connected boxes I'm liking, is there any kind of framework that supplies this sort of interface. I know it can be done using Qt but beleave it takes ALOT of work.
Does anyone know of frameworks for making this type of gui?
This is not c++, but i think it covers your problem, so i would suggest WireIt.
Examples:
http://neyric.github.com/wireit/plugins/editor/examples/logicGates/index.html
http://neyric.github.com/wireit/plugins/composable/examples/jsBox/jsBox.html
It is a Java Script library, so the browser would be your GUI. But i really think, that using the browser is a good thing to do. Learning HTML, CSS and Java Script is about as difficult as learning a new GUI framework. You could concentrate on HTML5 and ignore old browsers and maybe use a nice lib like jQuery, which is like the boost of js. Even if your GUI would only work on Firefox you would still support more platforms than most GUI-Toolkits.
You would of course have to embed a small http-server in your c++ code, you could use libmicrohttpd or mongoose for that.
In the end you have used tools that are very reusable and will have a broader applicability than GUI Frameworks.

I have Carbide.c++ Developer from Nokia and I want to create applications for my S60 phone.
I've looked at the samples that goes with the different SDK's for S60 but I haven't found any simple explanation on how strings, called descriptors, are used in Symbian.
One of the problems are that I'm visually impaired and therefore it takes quite some time to read through large documents that has page up and page down with lots of unuseful info and I've given up.
I'm willing to give it another try. Can anyone help me?
Here are a few sites on blogspot that may help. They have RSS feeds that will hopefully be easier to consume than paging through PDFs.

Yeah, The strings in Symbian is nightmarish.. atleast when you start with..
Here are few good references to help:
Introducing the RBuf Descriptor from Symbian Developer
Comparing C strings and descriptors from Forum Nokia discussion
Using Symbian OS String Descriptors from NewLC
I'd second http://descriptors.blogspot.com/ This is invaluable for getting to grips with Descriptors.
Also, sites such as newlc.com have forums for Symbian C++ specific code problems.
The best advice regarding descriptors I give to any new Symbian developer in my company is to try and avoid using the descriptors when not necessary. The Symbian SDK has the libc API which includes stdio, stdlib, string and more. I usually use char* types and when necessary I convert it to a descriptor (when I need to send a string to an SDK method which requires it).
