Some call it as feature, others treat it as bug - be what it may, you still have to address this if your application depends on the order of events in Qt. Consider the case where you have a QLineEdit object with editingFinished() handler, along with...

With latest NVidia Surround Vision and AMD Eyefinity advances combined with PCI-Express SLI and CrossFire facilities, multi-monitor setups at home and small firms have become a breeze (Couple of videos on YouTube demonstrate Multi-Monitor setups upto...

Continuing from Getting started , here we will see some of the basic tools and libraries that one should be acquainted with to make the cross platform development fun and easy (while respecting the audience request to consider non-Windows platforms also...

They say if you do not eat, drink, sleep C/C++ - then the chances are you are not a real developer. Is it? May be, may be not. But certainly if you have not done cross-platform development or design, you cannot claim to be a good architect or developer...

One of the questions that I come across developers asking frequently is "what is the best C++ MIDI library". It often goes unanswered unequivocally. The reason being, despite the presence of numerous C++ MIDI libraries out there, there is no single...

Here is a brief demonstration of Maya fluids, particle dynamics and Nurbs combined together to create an early morning Temple scene effect. The light source is being animated with soft body particle dynamics, while the smoke emitting from sticks is typical...

Here is a brief demonstration of tree growth animation in Vue. Animating the Diameter, Gnarl, Falloff, length and other related parameters gives the required result. Also note the growing grass at the base of the tree and the animated clouds. For...

After reviewing many existing C/C++ MIDI libraries, it appears JDKMidi seems to be the one having the features required by many midddlware libraries. However, JDKMIDI library (as of Revision 560) suffers a huge drawback of not being able to auto sort...

Autodesk, as usual, announced its next version of Maya at Siggraph. The interesting part, however, is the range of tools planned to be shipped as part of it: Maya Composite high dynamic range compositing system Matchmoving camera tracking...

You can use the following steps to make QT SDK work with your Visual Studio 2008 (either express version or commercial version). Download the QT SDK from http://www.qtsoftware.com/downloads/sdk-windows-cpp If you do not have VisualStudio 2008...

When a Water object is added to the Vue scene, it will be in a staic form without any animation applied to its surface. If you would like to have the water surface animated, then we have to enable its Displaced Water Surface property. This property allows...

Often an application requires to list all the Audio/Video compressors installed on the machine. We can achieve this easily with the ICreateDevEnum interface available from DirectShow. ICreateDevEnum exposes a method named CreateClassEnumerator that...

The MGlobal::getActiveSelectionList() offers a convenient way of accessing the currently selected objects in the view. However, if you wish to find the selected components then you need to use the MSelectionList's getDagPath() method. It returns the dagPath...

Given the DagPath for any Mesh object, listing the Shading Groups connected to it is easy. The MFnMesh::getConnectedSetsAndMembers() will do the trick as shown below: MStatus ListShadingGroups(const MDagPath& inputShapeDagPath) { if(inputShapeDagPath...

Tracking class variables' state changes can be tricky, especially if we are using too many asynchronous constructs. This is especially true for game and graphic application scenarios where hundreds and perhaps even thousands of object fly around...

If you are encountering errors with Poser Fusion shelf buttons in Maya such as "Error: No Selection, or the Currently Selected object is not linked to a Poser file", then try the below steps and see if its helps. First of all ensure that your...

If you are looking for a way of creating and accessing very large arrays, arrays that can handle content in the order of Tera Bytes, then probably you might find the File Mapping techniques useful for that purpose. File mapping is the association of...

Deriving a multiplication circuit for the Prime Factorization problem is trivial if you know how to convert the arithmetic and relational expressions into propositional logic. Below I will show few expressions and their corresponding CNF formulation...

If you check the CRT source code (inside VC\crt\src\crt0.c ) you can find an interesting function check_managed_app() that returns 1 if managed app, 0 if not based on the COM Runtime Descriptor in the Image Data Directory of the PE or PE+ header. ...

It is very rare that we come across a well-designed library every day, and even rare that we get a chance to work on them on daily basis. While it is hard to define what makes any given library "well-designed", it is rather easy to identify what is not...

MItDag offers a convenient way to iterate over the DAG nodes in any Maya scene, but not in a way that is useful for populating the visited nodes in a Windows tree control. This is because MItDag gives a linear list of nodes that make it a little...

If you are encountering an empty message box followed by a browse folder dialog in for MLibrary::initialize Open Maya SDK 2008, then the chances are that you can resolve the problem by defining the MAYA_LOCATION environment variable. Define the MAYA_LOCATION...

Are you planning to remove data-dependencies in your logic? You might find the below useful. Statement Block Constant Time Equivalent x++; if(x >= MAX_SIZE) x = 0; x = ( x + 1 ) % MAX_SIZE;...

As an answer to the question "are there finite mathematical descriptions that are not effective" posed by Hilbert, Turing provided the halting function as being not effectively computable despite being finitely expressible. This he established by devising...

If you are finding it difficult to send parameters from C++ to .Net, try if you can use the following class: -------------------------------------------------------------------------------------------------------------------------------- #ifndef...

Want to return an array of strings from native COM component to managed code? You need to declare the string array as SAFEARRAY(VARIANT) in the COM code. IDL for the function that returns the array of strings for the COM component would look...

Wouldn't it be nice if we could make our OS pay-per-use? We could rent our OS and all the required programs and let the customer pay per day or month as per his usage. We could host all our office programs, all our OS on Windows Live and let the users...

Having difficulties while loading the Side-by-Side assembly manifests for Registration-Free COM? Perhaps Activation context API could come to your rescue (Ref: http://msdn2.microsoft.com/en-us/library/aa374166.aspx ). The activation context...

Want to modify a managed string passed to a native function? I collected two ways of doing it. Either you can use System::Text::StringBuilder mechanism or you can use the array method mentioned at http://msdn2.microsoft.com/en-us/library/s04yfy1s(VS.80...
