Description

DDE

 

Dynamic Data Exchange (DDE) is a mechanism for interprocess communication in Microsoft Windows operating systems. Although the latest versions of Windows still support this mechanism, it is mainly replaced with more powerful mechanisms — OLE, COM and Microsoft OLE Automation. However, DDE is still used in some things inside Windows, particularly in the mechanism of associating filename extensions with applications. This mechanism can be used to get data from third-party applications.

 

Purpose

 

The plug-in is designed to send/receive data between a DDE server and this plug-in. Data exchange is carried out by server groups and their items specified in the configuration (see "Groups, servers and items"). After data is received, it is processed and grouped depending on the specified configuration and is sent for future processing and export.

 

How the program works

 

After the program is launched, the configuration tree is analyzed, during which it is checked whether the items exist on the server. If an item does not exist, the corresponding message is added to the log and this item will be highlighted in red when you open the configuration. If the DDE server is sending data at the moment, the program will start receiving the data according to the specified DDE items. Depending on the group settings, items can be exported simultaneously or one at a time, as well as with the date and time stamp. The program can also query DDE servers at the specified time interval and read the values of the DDE items. It is possible to specify a data type for each DDE item. Depending on the specified data type, it is possible to post-process, filter and export data later with the help of additional plug-ins.
