DDEITEM dialog element
Syntax
DIALOG ADD,DDEITEM,<name>
Description
DDEITEM dialog elements are invisible dialog elements that can be added to the main window of an application which has been created using the DDESERVER style. They provide a way for client applications to communicate with the server using Windows' Direct Data Exchange.
Client applications can send data to the server using the DDE POKE command, specifying the name of the DDEITEM dialog element as a parameter to the command. When this occurs, the server receives a <name>POKEDATA event, where <name> is the name of the dialog element that received the data. The server may read the data from the dialog element using the @DLGTEXT function.
A server may write data to a DDEITEM dialog element using the DIALOG SET command. Client applications can then read the data from the server using the @DDEITEM function, specifying the name of the dialog element as an argument.
Note: In DDE commands the name of the DDE item is case sensitive. So the name used in DDE POKE commands and @DDEITEM function calls must be exactly the same as that used when the dialog element was created.
