• disable Opera function key in javascript

  - by DonDon

  I'm writing javascript code for a web emulator containing function keys. The user is able to press keyboard function keys to process something in the emulator, I used stopPropagation and preventDefault javascript function to stop/cancel browsers invoking their function key shortcut (e.g. F1 will invoke Firefox to open its help page) and the code works fine under Firefox and Chrome. But Opera didn't work. I'm using latest Opera 10.5 here. Can anyone help ?

• wxpython Prevent Ctrl+Enter from changing the focus

  - by RSabet

  I have two wxListCtrl and want to process the Ctrl+Enter keyboard event without letting wx change the focus to the other ListCtrl. I have event handlers for wx.EVT_KEY_DOWN, wx.EVT_KEY_UP, wx.EVT_CHAR and KillFocus, but KillFocus is always called first, then the focus changes and the the keyboard handlers are called for the wrong ListCtrl. Is there a way to prevent wx from changing the focus, when Ctrl+Enter is pressed ?

• a good resource or book for architecting object-oriented software

  - by Ygam

  I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

• Oracle - truncating a global temporary table

  - by superdario

  I am processing large amounts of data in iterations, each and iteration processes around 10-50 000 records. Because of such large number of records, I am inserting them into a global temporary table first, and then process it. Usually, each iteration takes 5-10 seconds. Would it be wise to truncate the global temporary table after each iteration so that each iteration can start off with an empty table? There are around 5000 iterations.

• How can I implement a 'select all' check-box on my CRM 4 custom form?

  - by Gryphoenix

  I am working on a custom CRM form with numerous checkboxes, organized by sections. I would like to implement a 'select all' feature to the form and am trying to understand how to format the JavaScript. My research thus far has pointed me to the possibility of using a FOR statement to iterate through all of the elements in the section I want to process, setting their values accordingly, but am unsure of which document.getElements ... method to utilize.

• Java, user input to the command line when using Runtime.getRuntime().exec(command);

  - by user1557354

  I dont think this is possible, but I have been using: Process p = Runtime.getRuntime().exec(command); to run commands on the command line, but now I have come accross a situation where the command I am running part way through will ask for some user input, for example a username. This can not be resolved by a argument to the command that is being exec, is there any way I can pass the username to the same command line instance and continue? Thanks in advance.

• Opening a streaming connection to an HTTP server on iPhone/Cocoa environment?

  - by Paul

  I've been using NSURLConnection to do a HTTP post to establish the connection. I've also implemented the didReceiveData delegagate to process incoming bytes as they become available. As incoming data comes in via didReceiveData, I add the NSData to a data buffer and try parsing the bytesteam if enough data has come in to complete a message segment. I'm having a hard time managing the data buffer (NSMutableData object) to remove bytes that have been parsed to structs. Was curious if there's an easier way. Thanks
