[Pharo-project] ODBC on W7 and Pharo 1.4

by Torsten Bergmann

Sorry - no MSAccess installation here to help you with the problem. Dont know if ODBC package is still maintained. Maybe you should switch to DBXTalk which can also be used with ODBC http://dbxtalk.smallworks.com.ar/ Guillermo currently prepares a new version for OpenDBX 1.4.6. Bye T.

Re: [Pharo-project] How to filter out method extensions in Ring?

by HernÃ¡n Morales Durand

Thanks VerÃ³nica, now it works fine. I have one more question :) it is possible with Ring to query if a package is a "system" package? (included in the downloaded image). We've been talking about that feature in the list http://lists.gforge.inria.fr/pipermail/pharo-project/2009-December/018168.h… no solution was proposed.

[Pharo-project] [ENH]: Test Failure Browser

by Sean P. DeNigris

Issue 6457: [ENH]: Test Failure Browser http://code.google.com/p/pharo/issues/detail?id=6457 This can be included in the Jenkins test images... Browse or debug test failures serialized as fuel files. The Jenkins test script could be enhanced to leave an instance open if there are test failures, so that you would have a dashboard to work from just by downloading and launching the image... Todo: * Toggle button enabling (commented out right now, seems to be a bug in Spec - always passes nil to #whenSelectionChanged: * I want the initial width to be big enough for the contents; it seems like that should be the default. For now, I hardcoded an initialExtent * Layout: how do I specify a toolbar of buttons with static height and that the next row should take up the rest of the height, but not impinge on the toolbar?

I'm glad that snippet no longer exists in Pharo :) There is more cleaning to be done there, but at least we have the beginnings of a real model.

[Pharo-project] ODBC on W7 and Pharo 1.4

by Friedrich Dominicus

I'm not sure if I should post it here, but I can not see another place where I should post it. I've a problem with the fetching of Double numbers form an Access Database. I'll attach a test database. You can register this database in the ODBC configuration and then you just have to run: con := ODBCConnection dsn: 'testDB' user: '' password: ''. (con query: 'select * from tblTest') execute: ''. Then inspect the result and see the value of DoubleValue is wrong/broken. e.g it is: 123 and while fetchin it I get: an ODBCRow(#DoubleValue->2.0302831328797532e-307 #ID->1 ) Which sureley is some very very small number ;-( So I think the code for the data adaption may be the problem. AFAIKT the ODBCColumn Descriptions looks ok. Anyway there must be some kind of problem. Regards Friedrich
