Hi, I''m a newbie on both Ruby and Ruby on Rails, and I''m struggling with my first app. I have a table with a column called "employee_id" which is a foreing key associating it with the "employees" table.

I''ve spent all day digging through the rails api and postgres-pr on this, I think it''s time to ask the list. Postgres stores a Date in YYYY-MM-DD format. My users want the dates in MM/DD/YYYY format. Sure, I could explicitly convert it on the app level every place where a date is displayed, but that seemed like a DRY violation. I thought I''d be clever and simply

Hi All, I am using R 2.11.0 on a Ubuntu machine. I have a time series data set and want to run rolling regressions with it. Any suggestions would be useful.

I''m trying to make a ComboBox that can be typed into but only accepts entries that are already in the drop-down list. I hoped a combination of the CB_DROPDOWN style and a TextValidator with the FILTER_INCLUDE_LIST would make that happen, but the validator seems to be ignored.

Hi all, i am trying to use wxComboBox (instead of wxChoice) to capture wxTE_PROCESS_ENTER event. If i enable TE_PROCESS_ENTER flag on the resulting xrc file, i get an ''Unknown style flag wxTE_PROCESS_ENTER'' on app loading. Probably wxComboBox doesn''t reconize this kind of event.
