  • Disable inserted lines in multiline TextBox

    - by Shohin
    I have a multiline Textbox for my web page. When user logs in and enters text and press "Save" button, data will be saved. Then, next time when the same user logs in and searches for data, I want him to edit only new text in multiline TextBox, not removing or replacing previously entered text. Is there any way to make multiline TextBox to lock inserted lines or inserted text and allow to only add text? Thanks in advance.

  • active_scaffold routing error

    - by Elizabeth Buckwalter
    If you haven't seen my question yesterday, this is my second rails app. The first went nice and smooth, but this one keeps giving me one random error after another. I installed active_scaffold for this app as well as the last app (the first error, instead of using script/install plugin git://active_scaffold repository, I did script/install plugin http://active_scaffold repository.) I didn't want to spell out basic CRUD on minor models. After the install problems, (before I found the http solution from a windows user when I'm on Linux) I thought I'd try out Hobo. Well, Hobo updated actionmailer, actionpack, activerecord, activeresource, and installed rack. Rails isn't even using the updated versions. But as you can see at the bottom of the trace it's using rack. I have a feeling it has something to do with my futzing around with installing Hobo which I uninstalled. Thanks in advanced. [Edit] I had asked the question over at the ActiveScaffold Group the answer (if you don't want to follow the link) was that this line needed to be added to routes: map.resources :modelName, :active_scaffold => true It doesn't entirely answer my question, since the documentation said nothing about changing routes. But, it works.

  • Getting rid of the evil delay caused by ShellExecute

    - by korona
    This is something that's been bothering me a while and there just has to be a solution to this. Every time I call ShellExecute to open an external file (be it a document, executable or a URL) this causes a very long lockup in my program before ShellExecute spawns the new process and returns. Does anyone know how to solve or work around this? EDIT: And as the tags might indicate, this is on Win32 using C++.

  • Converting from a string to boolean in Python?

    - by Joan Venge
    Does anyone know how to do convert from a string to a boolean in Python? I found this link. But it doesn't look like a proper way to do it. I.e. using a built in functionality, etc. EDIT: The reason I asked this is because I learned int("string"), from here. I tried bool ("string") but always got True.

  • bit.ly API thumbnails

    - by user160222
    The bit.ly info API returns URLs for thumbnail images. When I attempt to access these images, I receive an access denied error. How do you access the thumbnail images generated by bit.ly? EDIT: I am testing the image URL by taking the URL provided by the info API and using the browser to access. Bit.ly returns an Access Denied error code. Do I need to somehow provide the login and apikey?

  • What the difference between a namespace and a module in F#?

    - by Dave Berk
    I've just started learning F# (with little prior experience with .NET) so forgive me for what is probably a very simple question: What the difference between a namespace and a module in F#? Thanks Dave Edit: Thanks for the answer Brian. That's what I wanted to know. Just a clarification: can you also open a namespace as well (similar to C# using statement)?

    - by st4ck0v3rfl0w
    Hi All, I was wondering if anyone had any good tutorials around creating a gmail inbox star (favorite) ?

One being a checkbox (for archiving, or batch deleting) and another I have a placeholder checkbox for favoriting. I'm just curious as to what the best approach is for making it snazzy with jquery.

  • Test sql connection without throwing exception

    - by Alexandre Pepin
    To test if i can connect to my database, I execute the following code : using (SqlConnection connection = new SqlConnection(myConnectionString)) { try { connection.Open(); canConnect = true; } catch (SqlException) { } } This works except it throws an exception if the connection failed. Is there any other way to test a Sql connection that doesn't throw an exception ? Edit : To add precision, i'm asking if there is a simple method that does that without having to open the connection and catch exceptions that can occur

  • Prevent diagonal scrolling in UIScrollView?

    - by NickD
    How can I force a UIScrollView in which paging and scrolling are on to move vertically or horizontally only? My understanding is that the directionalLockEnabled property should achieve this, but a diagonal swipe still causes the view to scroll diagonally instead of restricting motion to a single axis. Edit: to be clearer, I'd like to allow the user to scroll horizontally OR vertically, but not both simultaneously.

  • Online PHP/HTML/JS/CSS editor

    - by pistacchio
    Hi to all, is there any free php code that, once installed, allows you to browse and edit files (with html, javascript, php and css highlight) on the server where it's installed? The aim is to code online, browser based. I've tried http://phpanywhere.net/ that can make this possible, but it is buggy and moreover it requires an external (ftp) access to your server that is quite different (and less secure) that working directly on the server. Thanks in advance
