Andy, Hopefully this is the promised code. Getting this across town and through the layers of MS software has been interesting, to put it mildly. Bill

Re: [Pharo-project] ODBC: table names and column names/types?
by Benoit St-Jean Sept. 1, 2009

Sept. 1, 2009

I know, it's a mess... I have a persistence framework that supports DB2, Oracle, MySQL, SQLServer and Interbase and it's a nightmare whenever you try to do anything related to catalogs... And planning to integrate PostgreSQL as well... In case you wanna try to implement that stuff differently by calling the ODBC function, have a look at : http://msdn.microsoft.com/en-us/library/ms711831%28VS.85%29.aspx Caution: since you're in Linux, I'd also check iODBC (or whatever you use) for the same API... just in case they would differ (most likely!). This might be a simpler way to accomplish what you need... For Oracle, you might wanna query against the DICTIONARY view to get the same information... Hope this helps. ----------------- Benoit St-Jean Yahoo! Messenger: bstjean Blog: lamneth.wordpress.com A standpoint is an intellectual horizon of radius zero.

It might be helpful. Something similar works for the columns, but getting it to work with a where clause seems to be needlessly fragile. I have code that generates SQL that works just about anywhere, but not with the SQL server information schema. Given MS' involvement, I can't help but think that they might be using a different query engine or something equally stupid. I have also seen documention suggesting that this will not work with Oracle, which is also on my list. Still, this might provide a nice shortcut to the ODBC schema functions.

[Pharo-project] [ANN] Smalltalks 2009 - Third Smalltalk Conference of Argentina
by Andres Valloud Sept. 1, 2009

Sept. 1, 2009

Argentina's third Smalltalk conference, Smalltalks 2009, will be held from November 19th through November 21rd at the Facultad de Ciencias Exactas y Naturales (FCEyN), Universidad de Buenos Aires (UBA). All those connected with Smalltalk, be it faculty, students, researchers, developers or entrepreneurs, are invited to participate, free of cost, as presenters and members of the audience. The organization committee will announce the registration website shortly. The conference's goal is to gather both the Argentine and International Smalltalk community to get connected sharing our work and experience with regards to Smalltalk or related topics. Smalltalks 2009 presentations will be divided between the "Industry and Development" and "Research and Education" categories. In addition, the event will host a Smalltalk programming contest. As in other editions, well known personalities from the international community will attend the conference. The "Research and Education" category is the best match for research and education work done with Smalltalk in universities and public or private entities. The "Industry and Development" category is suitable for presentations related to Smalltalk software developed by companies or individuals, both public and private. A list of suggested presentation topics, not exclusive, is below: * Development tools. * Development with prototypes. * Model driven development. * Agile practices (XP, TDD, etc). * Web application development. * Metamodeling / metaprogramming. * New frameworks or models. * Materials for education. * Embedded systems and robotics. * SOA and web services. * Experience reports, both development and research. * Commercial systems. * Automation and best testing practices. * Interoperability with other technologies. * Best design and architecture practices. Interested presenters should keep in mind the following deadline schedule. 1. You must present a summary of the proposed presentation no later than Monday, October 19th, 2009. The summary must fit on a single page, and must include a description, objective, and category of the work to be shown. The submission procedure will be announced shortly. 2. The conference's program committee will select the event's presentations from the proposals submitted according to the above procedure by Monday, October 26th. The proposals including dynamic examples as opposed to just static presentations will be given priority. 3. The conference schedule will be published in the conference's website on Wednesday, October 28th. 4. The conference's works and presentations will be published in the conference's website after the conference. Those interested in the coding contest can become familiarized with it at the smalltalks-2009-coding-contest Google group: smalltalks-2009-coding-contest(a)googlegroups.com The contest's goal is to have a good time solving a problem in Smalltalk, and win a prize while at it. We are working hard to ensure everyone can participate, and we will show examples and prototypes that can be improved by the participants. For directions to FCEyN, you can go to the computer science department's web site: http://dc.uba.ar Feel free to share this invitation with those who might be interested. If you have any questions, send us an email at fundacion (dot) smalltalk (at) gmail (dot) com See you at the conference! Smalltalks 2009 Organization Committee.

[Pharo-project] Creating an event webpage

Hi ! Since there has been a number of events related to Pharo (sprint, dojo, ...), it would be nice to list them somewhere. Ideally, it should be the pharo-project.org website. A sprint will occur in Argentina this november. Where should I setup a page?

[Pharo-project] Don't ask me how to reproduce this one :)
by Schwab,Wilhelm K Sept. 1, 2009

Sept. 1, 2009

Hello all, I periodically see a degradation of anti-aliased fonts, and have no idea what causes it. Given my recent adventures in to startup/shutdown, I suppose it could be due to a problem there?? It seems to be triggered by saving the image w/o quitting. This recent occurance was different in that I started noting that the text in browsers looked different to me, perhaps just that the method name was not bold?? Something was not quite right, but the text still looked to be rendered well. Shortly thereafter, the full breakdown happened with everything rendered in an ugly font. It seems safe to save the image in this state, and exiting and re-loading the image fixes is. Any ideas? Bill
