I just created an application using the info you supplied
Console or windows app?
TEMailInfo, TExportInfo and TSQLServerInfo
They are records....
type
TEmailInfo = record
EmailNotification : boolean;
SMTPSvr : PChar;
PeopleToNotify : array of PChar;
end;
TExportInfo = record
ActivePlayersOnly : boolean;
DestPath : PChar;
BaseDataExport : boolean;
GlobalMatchCode : PChar;
end;
TSQLServerInfo = record
ServerName : PChar;
DatabaseName : PChar;
UserName : PChar;
Password : PChar;
end;
> DLL use properties from these objects/records?
Yes when it starts up it does use some of the properties of these records, but later on the messsages are just hard coded strings. I am seeing failure when the properties are being accessed.

Subject: [DUG]: DLL's - Sending feedback....
G'Day,
I have the following:
//Procedure called when processing
TProcessMessage = procedure(AMsg : PChar) of object;
TExportSessionSettings = record
LogToStdOut : boolean;
ProcessMessage : TProcessMessage;
EMailInfo : TEmailInfo;
ExportInfo : TExportInfo;
SQLServerInfo : TSQLServerInfo;
end;
library NCSQLToPDox;
{snip}
exports Perform_Export;
begin
end.
function DoExport(AExportSettings : TExportSessionSettings; AProcessMessage : TProcessMessage) : boolean;
The DLL can be called from both a command line application as well as a standard delphi windows application. Within the DLL should LogToStdOut be TRUE I have a WriteLn() call to write out logging messages. However as soon as I make the WriteLn call the DLL falls over in a heap. Similairly if LogToStdOut is FALSE and I use the supplied AProcessMessage the DLL also falls in a heap. So - How do I provide a mechanism of providing feedback to the caller of the DLL?
TIA
