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

1. Both of them can use Appwizard in vs ide To establish the framework. The former uses "MFC ActiveX Control wizard", and the latter uses "atl com Appwizard ". 2. The default extension of ActiveX controls created with MFC is ". ocx", and that of ActiveX controls created with ATL (Active Template Library) is ". dll ". 3. It is much easier to use MFC to create

active|activex|javascript| Function | Web page Objective Many netizens ask, in HTML page place a COM object, this object how to call the page script function problem, I recently also because the work needs to realize such function, after the internet search, got a lot of help, but did not find a complete implementation. This article describes several key points in the implementation process and provides a download of an example project. 1--To add a me

ActiveX controls in Pocket Internet Explorer. Therefore, the browser will verify whether the control is secure for the script. The verification is implemented through the IObjectSafety interface. When creating a control, the Pocket Internet Explorer for Pocket PC calls QueryInterface on the control to obtain the IObjectSafety value. If the control does not support this interface, the user will receive a pr

program, you can naturally Use ATL to support ActiveX Control inclusion. The example project demonstrates how to use the IE browser control. I have two advantages when selecting a browser control: Each computer has this control, and It has many methods and events and is a good example for demonstration. Of course, I cannot compare with those who spent a lot

People who have compiled mfc activex may have encountered the problem that Activex Control Test Container cannot be called after Rebuild all, although this is a small problem but when debugging a large project will encounter trouble that can not DEBUG-F5, the solution is as follows: Alt + F7 click Executable for DEBUG session on the debug properties page to change the actual path of

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

Recently encountered two requirements: 1 use worker threads in an ActiveX control to complete the underlying hardware Device scan task, and to callback the JavaScript function of the external Web page in the worker thread based on the result of the

Add # pragma once in the next line of the xxxctrl. H (XXX is the project name) header file // ------- Add ---------------// Cancel IE Security Prompt# Include "objsafe. H"// --------- Add ---------------------------- And declare part of the

Currently, many video sharing websites, such as Tudou, use the flash control as the player interface. However, it is very simple to use flash to implement full screen. You only need to set the fullscreen attribute to true, other players, such as mediaplayer, have properties similar to full screen effects. But how can this effect be achieved in custom ActiveX controls? The basic implementation is actually relatively simple. There are also many examples

This article demonstrates how to package the Qt application into IE and publish it. 1. Example Qt program: Create a project and select the Qt Library type. The class name is ClassDemo. Create a new QtGui class (inheriting QWidge) Class Name

minimize the use of advanced controls or Third-party controls, otherwise, the download has some problems. If the option for ActiveX in IE is set to disabled, the browser will appear with the dialog box "Current security setting prevents ActiveX controls from running on the page." Therefore, the page may not be displayed correctly, and this requires other ways t

objects can be written in any language, such as C ++, Java, and VB, and can be implemented using DLL or as an execution file for different process work. When using a COM Object Browser, you do not need to worry about the language in which the object is written, or whether it is executed in a DLL or another process. From the browser side, there is no difference. Such a general processing technique is very u

client simply uses the browser to access the server side via the HTTP protocol.A more mature solution is to develop an ActiveX control installed to the client so that the client's browser can access the local ActiveX control to perform the relevant local operation.What this article is going to talk about is developing

, you can save the project, and then compile and build the OCX fileSecond, call ActiveX in Intraweb1, the new Intraweb project will not say, add a Iwactivex control in the window, this control is used to load our ActiveXHere the main set of two properties: one is the ClassID property, the second is the CodeBase property, ClassID is the one we mentioned above the guid,codebase is to load the OCX file name, in this case I used a cab control price packag

mark before dynamic RTL, so that the ocx file you generate will not depend on the development environment of BCB.After completing the above steps, a simple ActiveX is created. You can select the register ActiveX Server under the run menu to register it. Then you can see your development results, if you need to publish to the Internet and register through a browser
