Invoked in:
Client or Server
Remarks:
This event is invoked in a client or a server whenever the DDE DLL detects an error. In most cases, eventparam contains the conversation ID for which the error was discovered. Sometimes, however, eventparam is 0. This can occur when an ESL program attempted to use an invalid or nonexistent conversation ID, or attempted to call a routine that requires an ID before any conversations have been established.
Ordinarily, an application would call DDEGetErrorID and DDEGetErrorString, and report the error to the user.
Available Queries:
Example:
response to stimulus DDE DDE_ERROR
copy eventparam to ConvID_IV
if(not(ConvID_IV = 0)) then
copy DDEGetErrorID(ConvID_IV) to ErrorID_IV
copy DDEGetErrorString(ErrorID_IV) to ErrorString_SV
else
copy -1 to ErrorID_IV
copy "Null Conversation ID" to ErrorString_SV
end if
