A string variable in which GetDataDDE will put the data |
Return value
Integer.
Returns 1 if it succeeds and -1 if an error occurs (such as the
function was called in the wrong context). If string is null, GetDataDDE
returns null.
Usage
GetDataDDE is usually called in the window-level script for a
RemoteSend event when your application is a DDE server or HotLinkAlarm
event when your application is a DDE client.
Examples
Assuming that your PowerBuilder DDE client application has
established a hot link with row 7, column 15 of an Excel spreadsheet, and
that the value in that row and column address has changed from red to
green (which triggers the HotLinkAlarm event in your application), this
script for the HotLinkAlarm event calls GetDataDDE to store the new value
in the variable Str20:

1 2 3 |
// In the script for a HotLinkAlarm event string Str20 GetDataDDE(Str20) |
