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

The use of multiple files in engineering is similar to the use of engineering itself.To add files to your project, follow these steps:1. Select "Project", "Add filetype" (here, filetype is the type of file). The Add FileType dialog box (Figure 4.2) is displayed.2. Select an existing file or a new file type and choose Open. When you add a file to your project, you simply incorporate a reference to the existing file into the project, rather than adding a copy of
local software, which brings great trouble to the customer. If the customer's software is not installed in D:/Program % 20 Files/QQ path, the path cannot be found, which lacks flexibility and is not desirable.2.

This function has been studied for a long time. It is easy to use ActiveX plug-ins written in C #. The server can also directly write data to folders, however, the client must install the framework, which is unrealistic for the customer.
Later, I studied how to use C ++ to implement ActiveX, upload post files to the server URL, and then accept post files. I was not familiar with C ++ for a long time, maybe I still don't use C ++, but Google and Baidu haven't found the correct solution.

Unfortunately, before OCX was available for popularization, the emergence of the
The person who uses Windows must not be unfamiliar with ActiveX control, which provides a call similar to DLL's dynamic-link library, but the only difference from a DLL is that ActiveX registration cannot be recognized and used by the system. So what happens when we get a message that ActiveX is not properly installed and cannot be used?
