Examples

If another PowerBuilder application called StartServerDDE to establish itself as a server using the name MyPBApp, then your application can act as a DDE client and call StartHotLink to establish a hot link with MyPBApp. The following statement ends that hot link. The values you specify for location and topic depend on conventions established by MyPBApp:

StopHotLink("Any", "MyPBApp", "Any")

This statement stops the hot link with Microsoft Excel for row 1 column 2 in the spreadsheet REGION.XLS:

StopHotLink("R1C2", "Excel", "Region.XLS")
