Bypass OutputDebugString in Delphi 7?

Question

I'm wondering if it's possible to bypass the OutputDebugString? I'd like the OutputDebugString output showing up in DebugView and not in the internal Delphi Event Viewer window. But i can't find a way to tell Delphi not to swallow the OutputDebugString. Any ideas?

regards

Answer 1

Not what the original question asked, I realise, but it's worth taking a look at CodeSite from Raize Software. It takes OutputDebugString to a whole new level. Messages (can) get directed to a CodeSite viewer which is roughly equivalent to a highly souped up DebugView. Well worth every penny IMHO.

Disabling "output messages" in the Event Log properties does not work?

Answer 3

I think there is no way around this. The situation is still the same in Delphi 2009. You should submit a feature request: http://qc.embarcadero.com

I'm wondering what the advantage instead of Delphi's internal event log window should be?

Answer 4

That is not possible.

OutputDebugString sends string to debugger (as its name suggests). There can be only 1 active debugger per process. You run your application under Delphi - Delphi got the messages, since its a debugger. You run your application outside Delphi - DebugView can access them, since no debugger claimed it.

However: WHY do you need this? Just disable other types of events in Delphi event log - and you'll get the same functionality as DebugView has.

Instead of DebugView you can try to use Process Monitor and its new "debug output" capability. It does not use OutputDebugString, it uses its own API, and there's also a Delphi wrapper here. You can use Process Monitor filtering features and Delphi won't trap that messages - but it's not a generic features as those of OutputDebugString.
