It just requires some work :) *** One of the common misconceptions surrounding Win32 programming is that you must decide early in the design process whether your application will be a console or GUI application. In reality, console applications can create windows and have a message loop just like a GUI application (see "Adding Graphics to Console Applications" by Michael Covington, Visual Developer, June/July 1997). Alternatively, graphical applications can create and use a console. Although Win32 provides functions for communicating with a console, they are a little clumsy to use and require parameters that are unnecessary for simple text I/O. This article shows how to use standard C/C++ I/O with consoles, and how to work around specific problems in the Visual C++ I/O library. *** http://dslweb.nwnexus.com/~ast/dload/guicon.htm > -- > best, > Eliot > -- Best regards, Igor Stasenko.

[Pharo-project] STDIO on Win

by Torsten Bergmann

Hi, havent yet played with the latest stdin/stdout stuff. Does this already work on Windows? At least I tried FileStream stdout nextPutAll: 'Yopla' in the latest 2.0 after starting Pharo-2.0-one-click.bat. Gives an error (write failed). Any comments?

Re: [Pharo-project] Inspecting keys in Dictionaries

by Davide Varvello

Hi Doru, I can say Glamorous :-) One more question: is it possible to modify a key in GTInspector? I can't find a way to do it, if write something in the evaluator it seems to me it does not appear in the dictionary.
