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

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
