-dimensional position, based on these can be achieved posture recognition.This body area, known as "skeleton" in the Kinect SDK V1, is renamed "body" in the Kinect SDK v2 preview. This section introduces the method of getting the body. The sample program uses the Kinect SDK v2 preview to get a sample program showing the body and color images overlay as "(dots)." Also, based on the body data, Hand State (the status of the hand) has also been shown. The 2nd section introduces the stage excerpt n

For beginner COM, a complete example is still quite troublesome. Recently I have been studying and learned the basic principles through my own exploration. Here we will explain a simple string example step by step. Source code download 1. Create a project First, use vs2010 to create a project. Select an empty project and name it mycom. 2. Create an Interface Class #ifndef IString_h__#define IString_h__#include 3. Create component classes #ifndef String_h__#define String_h__#include "IStri
To be honest, the final solution is to implement the idochostuihandler interface and solve it in the gethostinfo method. However, the "Implementation interface" means that the QueryInterface, addref, and release methods must be implemented, so the relevant code is:Class cmywebbrowser: Public idochostuihandler{Public:Cmywebbrowser () {m_cref = 0 ;}Virtual ~ Cmywebbrowser (){}Long m_cref;PRIVATE:Hresult stdmethodcalltype QueryInterface (refiid riid, void ** ppvobject){
Classes are not encapsulated, but some functions are concentrated in a file. One is the function declaration file dshowutilities. h, and the other is the function definition file dshowutilities. cpp. The functions mentioned here are all copied from the source code or help document provided by Microsoft. First, dshowutilities. h file # Ifndef dshowutilities_h _# Define dshowutilities_h _ # Include # Pragma comment (Lib, "strmiids. lib ") // This is just a small function, but it will be used in s
represent its structure. We can see that any structured storage file has a root istorage. This interface can contain multiple level-1 sub-istorage. level-1 sub-istorage can contain multiple level-2 sub-istorage, the hierarchy and tree structure of Structured Storage files are formed in sequence, and each istorage can contain any istream, which is equivalent to a single file in the file system. The main functions of istorage include: 1.1 stgcreatedocfile This function creates a structured stora
automatically compressed. These new features are implemented through COM modules and invoked as Plug-ins in the cleanup tool. Earlier versions were invoked through the Iemptyvolumecache interface, and in later versions of Windows 2000, the IEmptyVolumeCache2 interface was added, adding smaller updates. The Iemptyvolumecache interface consists of five functions, according to the order of the call, respectively: Virtual/* [local]/HRESULT

follows: A) audio codecs and Renderer For example, to play music in MP3 format, you must check MP3 Codec. B) Video codecs and Renderer C) DirectShow This includes the Core Components and filters of DirectShow. DirectShow uses filters to complete core functions. If the DirectShow component is not added, use the SDK exported by the system. It is likely that our DirectShow application compilation will fail. Even if the compilation is successful, it cannot work normally. In addition, there are M

Gifolecontrol can insert images, including BMP, JPG, and PNG. The image size is not limited. The key point is that GIF animation can be inserted in RichEdit. Currently, swf format cannot be inserted. At the same time, you can directly display tooltip In the inserted image and GIF to facilitate the application. The interface defined by gifolecontrol is as follows: Interface igifctrl: idispatch {[Propput, Bindable, requestedit, ID (dispid_bordercolor)]Hresul

In Arcengine, many components send information in event mode. For example, in Mapcontrol, there are events such as mouse press events, mouse movements and so on, Iworkspaceedit also have the beginning edit, end edit and so on. Sometimes we need to be aware of these events in order to process the necessary information when they occur. So, how do you listen to events for components? The following is an example of a listener editing event to illustrate how listening is handled. To turn on help, we'
the event source interface definition. The first is to share a common header file, as shown below. The second is to use the #import in conjunction with the Embedded_idl import qualifier so that the event source type library is written to the. tlh file that retains the code generated by the attribute.Firing eventsTo fire an event, simply call the method in the interface that is declared using the __event keyword in the event source class. If the handler is hooked to an event, the handler is invo
