Basic concepts of 1.ActiveX An ActiveX control can be thought of as a very small server application that cannot run on its own and must be embedded in a container program and run with that container. This container includes Web pages, application forms, etc... The suffix name of the ActiveX control is OCX or DLL. Usually in the form of OCX and Dynamic Library co-

register a COM server outside the process, you can ignore the normal way in which the program works during manual startup. The sub main or class_initialize program will not be called and will run only when this programming environment includes the registration logic in the EXE file. Vi. Summary the above briefly summarizes the concepts related to ActiveX Components in daily learning. In terms of registr

This article will first show you how to use Visual Studio to develop a simple ActiveX control, and then describe the basics of ActiveX control development, such as methods, properties, and events, and finally how to use this knowledge to communicate between ActiveX controls and page pages.of the Myactivex controlBrief introductionActiveX was a technology introduc

Development tools: 1. Visual Studio 2005 for ActiveX component development 2. Microsoft ActiveX control pad is used to generate HTML webpages containing ActiveX control. Steps:1. Create an MFC ActiveX Control Project Using Visual Studio 2005. After compilation, find a file XXXX. ocx in the debug/release directory.

The workaround is to define a static ActiveX object in the form class that assigns the ActiveX object on the interface to the newly defined object in the Formload class, which is accessible to the static object.public static Axclientdriver_ntlib.axclientdriverctrl com = new Axclientdriver_ntlib.axclientdriverctrl ();private void Form1_Load (object sender, EventArgs e){com = THIS.AXCLIENTDRIVERCTRL1;IsRunnin

First, prefaceAfter several studies, now we have mastered the entire development process of ActiveX, but to play the true power of ActiveX, must rely on JS. Let's learn now!Second, JS call ActiveX methodSimply write a public method in the UserControl subclass (that is, the custom ActiveX control).C#[Guid ("0203dabd-51b

Conditional loading of ActiveX events when ActiveX is used When ActiveX is used, events are directly added to the page. For example: 1) Call voice TTS ActiveX Script Type = "Text/JavaScript" Language = "JavaScript" > VaR Voiceobj = Null ; // TTS object Voiceobj = New

After Microsoft assigned SP2 to IE, when ie opened some web pages containing ActiveX controls, a prompt box is displayed, asking the user to choose whether to install the control; by default, common users do not know what is going on. The company's products also encountered such problems. The only way is to make the control into an EXE file for users to download and manually install and register. In this way, a test is required, if the user does not i

In the previous essay: ActiveX (a) The first simple demo, JS one-way call ActiveX methods can be implemented, in many cases, the execution of methods in ActiveX is relatively time-consuming and performance-intensive. In this case, the ActiveX method executes using the asynchronous policy, then how can JS get asynchrono

Javascript calls functions in ActiveX Controls The key to this interaction is to add external methods to the interface class. The procedure is as follows: 1. Create an MFC ActiveX project in. net 2. in the class view, you can see a "project name + lib" item at the bottom. The icon is different from the class icon above. expand it and you can see three items, the following is how to add an external functi
