I don't know how I missed #readFrom: while I was digging around in the browser, but I did. I do much of my work on a Handheld, and one of the downsides is limited screen real estate (and a stylus is a poor substitute for a mouse). However, I always wind up learning about 40 other things on the way, which seems to be one of the many enjoyable facets to learning to program Smalltalk -- now that I'm getting through my adjustment to pure object-oriented programming. Thanks also for the gentle reminder about using "implementors of..." as a way to get some more insight into the subclassing. Kindest regards, Cam Bowes cbowes(a)mnsinc.com

Reading Dictionary from File
by Cameron Bowes 05 Dec '98

05 Dec '98

Hi Folks! I've got a dictionary of timing data that I keep in a text file. I finally decided to work up a couple of methods to basically dump the thing out and read it back in. To dump it, I open a FileStream and use storeOn: to stream it out to the file. So I have a file with the Dictionary all neatly arranged to be read back in. Which I can cut and paste into a workspace with a variable assignment to recreate the Dictionary. I'd like to read it back in directly from the file though, and this is where I'm stumped (yes, I'm a relative newbie). I open the FileStream, and then use contentsOfEntireFile to grab the data, which passes me back a string. Assigning that to a variable gives me just that, a string. What I'd like to do is pass the thing to the variable so that the Dictionary definition gets recreated. I think I must be missing something really simple here! TIA for any suggestions! Regards, Cam Bowes cbowes(a)mnsinc.com

This is entirely inappropriate for the Squeak mailing list. I will not be drawn into a pointless exchange dragging this list increasingly far off topic. 'nuff said. Bill F.

Agreed. Money/etc isn't a zero-sum game; look at the boundary cases to see that.

It had the idea of the entire desktop being a stage and you created the cast. And it had a fully OO language to program in. One of the nicest environments I've ever seen.

[Win95] Bug: Recursive not understood error encountered
by mwai＠ibm.net 04 Dec '98

04 Dec '98

I just encountered a bug as follow: While using Celeste to check my email, right after downloaded all the messages, an error dialog pops up: 'Recursive not understood error encountered'. At the time, I was using full screen Squeak and when the error occurs, the screen splits into two parts (Squeak window at the top and a debugger look-alike window at the bottom) with the bottom part as a scrolled window showing a stack of integers and symbols. I have absolutely no idea what the numbers mean. It looks like debugger info because I saw some symbols which resemble optimized block (i.e. >>[]). In addition, while I can scroll up and down in the bottom window, I can do absolutely nothing in the Squeak window. That is, no response at all on everything, including user interrupt. Finally, I have to use windows task list to kill the whole squeak environment. -------------- In order to avoid another email, 1) Is it a known bug that when I exit a morph project, I have to 'restore display' everytime? Otherwise, the screen would really screwed up (e.g. it doesn't redraw overlapped/destroyed windows) 2) Del key doesn't work in Celeste editor (in Wintel anyway) 3) I created a lot of morph projects under 2.2 and I don't want to lose the settings, how could I 'save' them and reuse them in 2.3? I thought that it must be trivial but I couldn't find an option for saving /exporting a project. Thanks. Mark Wai
