the ID to determine which method (or attribute) of the specified object to call. Therefore, the method used to call the object through the method (or attribute) name is, you must call the getidsofnames method of idispatch to convert the method (or attribute) name to an ID before calling the object method through the invoke method of idispatch. To facilitate operations, three functions are encapsulated to call the methods of the webbrowser object, read the attributes of the object, and set the a
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
ispvoice interface also has many member functions. For more information about the usage, see the SDK documentation. The following describes the usage of several major functions:
Hresult speak (const wchar * pwcs, DWORD dwflags, ulong * pulstreamnumber); function: refers to the Speak parameter: * The text string entered by pwcs, which must be Unicode, if it is an ANSI string, it must be converted to Unicode first. Dwflags is used to mark the mode of s
All along, I used the New RegExp to create regular expression objects:
Set regex = new RegExp However, it is also possible to create a regular expression object that is new to the VBS:
Set regex = CreateObject ("VBScript.RegExp") it seems that none of the VBScript books I've read has been written about this, and of course there's still a lot of stuff that's not on the books.
Now that a regular expression is mentioned, by the way, the regular expression object of VBS supports MultiLine mode, and

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
method (or property) name to an ID before you can invoke the method of the object through the IDispatch invoke method. For ease of operation, three functions were encapsulated to invoke the WebBrowser object's method, read the object's properties, and set the object's properties. DispID Cwebbrowserbase::findid (IDispatch *pobj, Lpolestr pName) {DispID id = 0; if (FAILED (Pobj->getidsofnames (iid_null,pname,1,locale_system_default,id))) id =-1; return ID;}
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

2. COM component function call (invoke of idispatch)Assume that there is a component whose progid is "atlfunc. mymath.1". The attributes and interface methods are as follows
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
The idispatch interface is the core of COM automation. In fact, the idispatch interface is also very simple, there are only four methods:
IDispatch : public IUnknown { public: virtual HRESULT STDMETHODCALLTYPE GetTypeInfoCount( /* [out] */ __RPC__out UINT *pctinfo) = 0; virtual HRESULT STDMETHODCALLTYPE GetTypeInfo( /* [in] */ UINT iTInfo,

Using namespace AccountDriver;
In this way, you only need to define the Smart interface pointer IAccountPtr:
IAccountPtr m_account;
The call to functions and attributes in the Code component is the same as that in the first two methods, and the access is completed through m_account. Because of the introduction of the _ com_ptr_t template class and smart pointer, the # import command method is the simplest method to use the COM compone
