Hello out there, thanks to all of you who tried to help me with my previous question. Why would I want to have a console app and then hide it? Well, let me explain. - I have written a DLL to provide some funtionality. It sits completely in the backfround, not using any GUI nor stdin, stdout or stderr. - When this DLL's functions are called from a console app, everything is fine. - When called from a GUI app, everything is fine. - BUT one customer reports that when called from an OLE-server he receives an error message like 'cannot find stderr'. 1) Yes, this message comes from my DLL - I found the text in one of the libs my DLL uses. 2) Why? No idea, like stated above, normally it just works - on my machine it even works when called from the customer's OLE-server :( Looking at the OLE-server's sources I see that it is created as a normal GUI app with an immediate call to Application.Hide to make it invisible. One idea is now to mimic this behaviour: - Create the server as a console app -> this would give me stderr, so we would avoid said error message (and might even learn something from whatever message is wanting to be sent) but - hide the console (possibly in a second step) to have the same behaviour as we have now. Whether this will be the solution, I don't know yet - having a customer report a problem I cannot reproduce (even on the same OS) is not the easiest of situations. I'd be greatful for any comments, ideas or suggestions. Best regards Helmut Giese
