  • Best practices: displaying text that was input via multi-line text box

    - by chris
    I have a multi-line text box. When users simply type away, the text box wraps the text, and it's saved as a single line. It's also possible that users may enter line breaks, for example when entering a "bulleted" lists like: Here are some suggestions: - fix this - remove that - and another thing Now, the problem occurs when I try to display the value of this field. In order to preserve the formatting, I currently wrap the presentation in <pre> - this works to preserve user-supplied breaks, but when there's a lot of text saved as a single line, it displays the whole text block as single line, resulting in horizontal scrolling being needed to see everything. Is there a graceful way to handle both of these cases?

  • Query scope within a table trigger in an Oracle database

    - by sisslack
    I'm been trying to write a table trigger the queries another table that is outside the schema where the trigger will reside. Is this possible? It seems like I have no problem querying tables in my schema but I get: Error: ORA-00942: table or view does not exist when trying trying to query tables outside my schema. The documentation seems to elude to this notion, but it's not 100% clear to me.

  • Best keyboards for emacs?

    - by catphive
    For emacs users out there, what are your recommended keyboards? Bonus points for keyboards that: Have no capslock key. Instead, a control key in that position. Alt keys that are closer to the center, and easier to use with meta key combos. I find alt keys too far to the left to be a bit awkward to hit with my thumb in some key combos. Help ergonomically with emacs in other ways. I'm not a huge fan of model M style high and clacky keys. I instead prefer laptop style flat keys; however, I'm not disqualifying either category.

  • Best client for SVN / WIndows for READ ONLY ;)?

    - by TomTom
    Not interested in any source control OR shell integration. This is basically to make regular gets on certain third party archives. I would really prefer not to deal with SVN in any way in my shell or visual studio. Native / C# preferred (as i have those runtimes already installed). Anyone a recommendation under those circumstances?

  • best method for creating a universal extention/plugin

    - by rashcroft44
    Hi, I'm looking to create an extension for the leading browsers (firefox, safari and ie). Its rather simple, and I'm looking for the most efficient way to go about this. I need to get the hostname of the current site the user is on, and if it matches a certain parameter(eg, mysite.org), I'll need to append to the link some extra data and refresh to the new link. What is the simplest way to go about this? (I don't want to go in the direction of a bookmarklet - since this would require the user to click. I'd like this to happen automatically) sort of something like this: if(window.location.hostname == 'mysite.org') { location.replace(document.location.href + '/&mystuff=xyz'); } Thanks!

  • Best way to update UI from other classes?

    - by Jack
    I've got several nested classes, with the following structure: BackupLocation contains list of BackupClients BackupClients contains a list of BackupVersions BackupVersions contains a list of BackupFiles In my UI - Im populating a combo box with BackupLocations - and have several listboxes for the clients, versions, and files. When processing the BackupLocations - I can update my status bar easily because thats the top level class that the UI creates. But how can I update the status bar and progress bar on each file being processed? Since the BackupFiles are 3 levels deep, I cant see any way to update the UI. The actual processing of the files are within the BackupVersion class - which loads its files. I think it probably has something to do with events and delegates - but am unsure exactly how to proceed with this, any help would be appreciated.

  • What is the best way to expose a callback API - C++

    - by rursw1
    Hi, I have a C++ library that should expose some system\ resource calls as callbacks from the linked application. For example: the interfacing application (which uses this library) can send socket management callback functions - send, receive, open, close etc., and the library will use this implementation in stead of the library's implementation. (This way enables the application to manage the sockets by itself, can be useful). This library has to expose also more callbacks, like, for example, a password validation, so I wonder if there is a preferred method to expose the callback sending option in one API. Something like: int AddCallbackFunc (int functionCallbackType, <generic function prototype>, <generic way to pass some additional arguments>) Then within my library I will assign the callback to the appropriate function pointer according to the functionCallbackType parameter. Is there any way to implement it in a generic way which will fit ANY function prototype and ANY additional arguments? Your help will be more than appreciated... Thanks!

  • WPF tooltip best practices

    - by Martin
    I'm about to change my application to include tool tips for all buttons, combo boxes, etc. I was wondering if there are any recommendations on doing this. For every control I'd like the tooltip to show the control's name in bold, followed by the description. I want to keep the style separated from the control, so I can change the tooltip style globally. What I would like to have, unless there's a better suggestion, is two additional fields per button/combobox/etc: 1-ToolTipName and 2-ToolTipDesc, both containing a string. How can I accomplish this (and is it even possible?).

  • best PHP programming approach?

    - by Nazmin
    Hello guys, i guess that many of us has acceptable years of experience in PHP programming, me myself got 5 years programming in PHP since in University (not very solid), i just want to gather some suggestion here, what is better approach in PHP OOP? Since there is a lot of PHP framework out there as well as javascript framework, can anyone share their experience in using one of them as well as using both of the PHP and javascript framework together especially for developing enterprise system? (my company want to start using framework, ISP company) if someone has his/her own framework or class or php file so on and so forth, mind to share? now I've only database connection class. I've never use any php framework before, just jquery as javascript framework, my company has a messed up of programming approach because they did not actually a software house, so all the files are scattered across the server, I see that there are some question before about the framework but i just want to know you all approaches on OOP and in developing massive web apps using PHP, or maybe someone kind enough to share their solid written class. Also pro's and con's of all this things. Thanks in advance.

  • Best way to design a class in python

    - by Fraz
    So, this is more like a philosophical question for someone who is trying to understand classes. Most of time, how i use class is actually a very bad way to use it. I think of a lot of functions and after a time just indent the code and makes it a class and replacing few stuff with self.variable if a variable is repeated a lot. (I know its bad practise) But anyways... What i am asking is: class FooBar: def __init__(self,foo,bar): self._foo = foo self._bar = bar self.ans = self.__execute() def __execute(self): return something(self._foo, self._bar) Now there are many ways to do this: class FooBar: def __init__(self,foo): self._foo = foo def execute(self,bar): return something(self._foo, bar) Can you suggest which one is bad and which one is worse? or any other way to do this. This is just a toy example (offcourse). I mean, there is no need to have a class here if there is one function.. but lets say in __execute something() calls a whole set of other methods.. ?? Thanks

Just want to know if there is better way to go about this.
