Requirements:
Publish an MFC serial control program using mscomm32.ocx. OCX needs to be registered.
You can manually register OCX and enter the following statements in the command line. A prompt will be displayed after successful registration.

There is no way, practice proved that the best solution is to write an OCX control, so as long as the registration of OCX control can be, at the same time OCX control scalability is very large, that is, to vc\delphi the functions of these programs into the Web, its function can be imagined!
This does not explain the OCX

Recently I am studying ActiveX technology. I used Delphi 7 to create an ActiveX control application with activeform. This control generates a. ocx file. Now, I need to deploy this control on the server. When you browse the Web page and choose to install this control, your IE will download, install, and display this control.However, my control must be digitally signed before Ie can be downloaded and installed.

When selecting folders in Web application development, this is troublesome for web programmers. Because of local security restrictions, JS cannot access local files, folder selection is generally avoided, when I was writing a program, I also encountered the same problem. I started to use js to traverse the file. The result was not successful and there was no way to do it, practice has proved that the best solution is to write an OCX control by yoursel
I,ProgramDescription:Program environment: Windows XP SP2, ie 6, Tomcat 5.5, VC ++ 6.0
Program process: the control is made into an ocx file for the client to call local hardware, which is useful to several third-party. DLL files. Windowsself-carried iexpress.exe is packaged into a cab file, and controls are called on the JSP page of the server side. The cab file is downloaded and automatically registered.

The ActiveX technology is implemented by generating "*.ocx" files. First to understand the next OCX file, in the Baidu Encyclopedia on the face of OCX is this explanation: ". ocx is an extension of the OCX control, and OCX is an o
The unclear (especially Chinese) font in TD8.0 seems to be 8 pounds, and it's clear to change to 9 pounds. But TD8.0 does not provide a font-changing feature. Under the guidance of high man, I found and modified the font settings.
When you connect to the TD8.0 server for the first time, some files are downloaded, including the files that control the font. The downloaded file controls the TD8.0 font.
This file on the client is the Tdclientui80.ocx that
callback function at the entrance, as far as possible to back up the incoming data into the local variables (of course, the variables used for inter-thread communication can not be handled so), only the local variables are processed, can be a good solution to this problem.2, in MFC, please use the thread carefully. Because the framework of MFC assumes that your message processing is done in the main thread. The first window handle belongs to the thread, and if the thread that owns the window ha

The ActiveX control runs on the client. We can get some information about the client, such as IC card information, client authentication and so on. However, the ActiveX control also has many disadvantages: The client's deployment is difficult, such as the client can not download correctly, the download can not be correctly executed, download the time required to set IE security level and so on.

ActiveX controls can be used to quickly reuse small components and share code, improving programming efficiency and reducing development costs. However, ActiveX controls cannot be directly used by end users, because ActiveX controls must be registered in Windows first. Generally, there are six ways to register ActiveX controls. They have their own advantages and have different application scopes.Regsvr32.exe RegistrationRegsvr32.exe is located in the system subdirectory of the Windows directory.
If your computer and IE cannot run JavaScript code, and the setting tool --> inerter option --> security cannot be used after Javascript is enabled, you can try the following methods.
Create an ierepar.txt file, copy the following content, and rename it ierepar. bat. Double-click the file to run the batch processing. After the batch processing, the file can be restored.
Regsvr32 actxprxy. dll/s
Regsvr32 shdocvw. dll/s
Regsvr32 urlmon. dll/s
Regsvr32 actxprxy. dll/s
Regsvr32 shdocvw. dll/s

Batch Processing solves problems such as IE does not support JavaScript and dynamic web pages cannot be displayed.
IE does not support JavaScript! In the Internet option-> Security-> Custom Level-> script settings do not help.Some DLL files are "deregistered" and need to be registered again!

Summary of Solutions to CHM File Failure I have recently heard a friend say that the CHM file cannot be opened and I have encountered it today. Summary of the methods on the Internet:
1. If the file cannot be opened, you can restore the file association as follows:1. Start running. Enter regsvr32 C:/Windows/system32/hhctrl. ocx. OK. Re-associate the file.2. Execute hh.exe in the external Windows Directory (if hh.exe is lost, copy the file in a normal
Although Microsoft does not trust ActiveX more and more, many people prefer this technology. The editor of this blog seems to have used ActiveX.
After the OCX control is compiled, it can only be released after it is packaged into a cab file and added with a digital signature. If you are using vc6, the problem is simple, after packaging, you do not need to consider the control Runtime Library. The current XP system and the 2kpro to be eliminated alread
