I just
created an application using the info you supplied, and it worked ok. Are
TEMailInfo, TExportInfo and TSQLServerInfo classes or records? In order to
formulate the message, does the DLL use properties from these
objects/records?

Subject: [DUG]: DLL's - Sending feedback....
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-- Donovan
