• MonoTouch Hello World for iPad

  - by Bryan

  I have tried following the sample Hello World for MonoTouch by creating an iPad solution. For some reason I cannot get the MainWindow to load. I followed the instructions exactly and the app just closes before even loading a view. Is there something missing? Do I need to tell the solution how to load the MainWindow.XIB or something? Please help, this seems very basic and I am about to throw MonoTouch in the garbage.

  - by code007

  Hello all, I have added a UIButton in the header section of the UITableView via the interface builder and would like to remove the access to the button in certain cases.

• Grouped Select in Rails

  - by Neil Middleton

  Simple question really - how do I use the select(ActionView::Helpers::FormOptionsHelper) with grouped options? I have got it working with a select_tag (ActionView::Helpers::FormTagHelper) but I would really like to have it using a select tag to match the rest of the form. Is this possible?

• How can I use "FOR UPDATE" with a JOIN on Oracle?

  - by tangens

  The answer to another SO question was to use this SQL query: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o JOIN ( SELECT DISTINCT Id FROM table1, table2, table3 WHERE ... ) T1 ON o.id = T1.Id Now I wonder how I can use this statement together with the keyword FOR UPDATE. If I simply append it to the query, Oracle will tell me: ORA-02014: cannot select FOR UPDATE from view Do I have to modify the query or is there a trick to do this with Oracle? With MySql the statement works fine.
