  • how to customize django admin for clickable list_editable

    - by FurtiveFelon
    Hi all, Currently, i have a class MyAdmin(admin.ModelAdmin), and i have a field in there called name, which belongs to both list_editable and list_display. The current behavior is such that all fields that is in list_editable displays a form field. However, i would like to change that only when people click on the field would it turn into a editable form field. Can anyone point me in the right direction on how to do that (which template to edit etc.). Thank you very much! Jason

  • Using a constructor for return.

    - by Fecal Brunch
    Hi, Just a quick question. I've written some code that returns a custom class Command, and the code I've written seems to work fine. I was wondering if there are any reasons that I shouldn't be doing it this way. It's something like this: Command Behavior::getCommand () { char input = 'x'; return Command (input, -1, -1); } Anyway, I read that constructors aren't meant to have a return value, but this works in g++. Thanks for any advice, Rhys

  • Asp.net ajax combobox doesn't display correctly when inserted inside a tab control.

    - by Shimrod
    Hi everybody, I have a display problem when I try to use a ajax combobox inside a tab control: when my tab control loads on the page where the combobox is, everything works fine; however, if it loads on a another page, the you change to the page which contains the combobox, the right button (which opens the list of the combobox) isn't displayed at all. Has someone been through this behavior? And maybe found a solution ? Thanks in advance !

  • MessageBox.Show-- font change?

    - by mmr
    Hi all, I'm using the MessageBox class to show errors to users, and while that might not be the right behavior, it's very convenient. This is a touchscreen application, however, so I need the 'ok' button to be much larger than it is (curse my inordinately large fingers!). I think that if I increase the font size in the dialog box, I should be ok. Is there a way to do that? Or really, is there any way to increase the dialog size? Thanks

  • Code golf - hex to (raw) binary conversion

    - by Alnitak
    In response to this question asking about hex to (raw) binary conversion, a comment suggested that it could be solved in "5-10 lines of C, or any other language." I'm sure that for (some) scripting languages that could be achieved, and would like to see how. Can we prove that comment true, for C, too? NB: this doesn't mean hex to ASCII binary - specifically the output should be a raw octet stream corresponding to the input ASCII hex. Also, the input parser should skip/ignore white space. edit (by Brian Campbell) May I propose the following rules, for consistency? Feel free to edit or delete these if you don't think these are helpful, but I think that since there has been some discussion of how certain cases should work, some clarification would be helpful. The program must read from stdin and write to stdout (we could also allow reading from and writing to files passed in on the command line, but I can't imagine that would be shorter in any language than stdin and stdout) The program must use only packages included with your base, standard language distribution. In the case of C/C++, this means their respective standard libraries, and not POSIX. The program must compile or run without any special options passed to the compiler or interpreter (so, 'gcc myprog.c' or 'python myprog.py' or 'ruby myprog.rb' are OK, while 'ruby -rscanf myprog.rb' is not allowed; requiring/importing modules counts against your character count). The program should read integer bytes represented by pairs of adjacent hexadecimal digits (upper, lower, or mixed case), optionally separated by whitespace, and write the corresponding bytes to output. Each pair of hexadecimal digits is written with most significant nibble first. The behavior of the program on invalid input (characters besides [a-fA-F \t\r\n], spaces separating the two characters in an individual byte, an odd number of hex digits in the input) is undefined; any behavior (other than actively damaging the user's computer or something) on bad input is acceptable (throwing an error, stopping output, ignoring bad characters, treating a single character as the value of one byte, are all OK) The program may write no additional bytes to output. Code is scored by fewest total bytes in the source file. (Or, if we wanted to be more true to the original challenge, the score would be based on lowest number of lines of code; I would impose an 80 character limit per line in that case, since otherwise you'd get a bunch of ties for 1 line).

  • Adding outlets to UIButton

    - by alltom
    For quickly mocking up UI, I'd like to be able to drag buttons onto a view in interface builder, then drag a connection from that button to the view that should appear when you click it. A subclass of UIButton is a little inconvenient to use in IB, so I'd prefer to add the behavior to UIButton itself. Unfortunately, it seems like outlets created in a category aren't visible in IB: @interface UIButton (myextensions) { IBOutlet UIView *outletDestination; } @end Can extra outlets be added this way?

  • Is it possible to have yui editor change paragraph style without selecting text?

    - by user126861
    Is it possible to change the behavior of the yui text editor so that when you make markup changes (via the toolbar bar buttons), for example changing from a paragraph to say a heading or to a list, and you dont have any text selected it assumes you mean the current block that the cursor is in So to change a paragraph to a heading rather than selecting the whole line you just place the cursor somewhere in the paragraph and select heading from the styles drop down.

  • Facebook JS SDK FB.logout() doesn't terminate user session

    - by Casey Flynn
    I'm attempting to log a user out of facebook with the Facebook JS SDK, however calling: FB.logout(function(response){ console.log(response); }); returns: response.status == "connected" And only after refreshing the page does the SDK realize that the session has ended. Anyone know what could be causing this behavior? This code previously worked in my application and has recently started behaving this way. Another example using FireBug:

  • A Question on Encapsulation.

    - by Bragaadeesh
    Hi, I know that encapsulation is binding the members and its behavior in one single entity. And it has made me think that the members have to be private. Does this mean if a class having public members is not following 100% Encapsulation rule? Thanks

  • Mcafee PCI Compliance failing on Session ID cookie?

    - by frio80
    Hello there. I am attempting to obtain PCI compliance for my site but the Mcafee security scan has thrown a: Potential Sensitive Persistent Cookie Sent Over a Non-Encrypted (SSL) Channel Drupal (default behavior) sets a session cookie when you simply arrive at the site. This is causing the problem. Clearly, the entire site shouldn't be under SSL; plenty of other sites set session cookies like this. What gives?

  • Why do condition variables sometimes erroneously wake up?

    - by aspo
    I've known for eons that the way you use a condition variable is lock while not task_done wait on condition variable unlock Because sometimes condition variables will spontaneously wake. But I've never understood why that's the case. In the past I've read it's expensive to make a condition variable that doesn't have that behavior, but nothing more than that. So... why do you need to worry about falsely being woken up when waiting on a condition variable?

  • ASP.NET mvc 2 Validation always shows errors on initial page load.

    - by gt124
    I've searched around a lot, and honed this problem down to this case: I'm using the PRG pattern, pragmatically I'm using the same DTO for my post/get actions. It looks like when I have the dto with the data annotation attributes in the get action parameter list, the validation is always displaying errors, every time on initial page load. In some cases this could be desired behavior if you put asterisks in the error message, but how do I get rid of it? Thanks in advance.

  • Can I swap WCF deserializer from configuration?

    - by JohnIdol
    I have a problem with WCF deserialization where the client hangs on the response for more than a minute. I'd like to try to swap different deserializers and see if it affects the behavior. Can I swap in/out different serializers (are there any others?) from configuration, and if so can I do that with any binding, or is that out of control once the service reference is imported? Any help appreciated!

  • POSIX: allocate 64KB on 64KB boundary.

    - by Eloff
    I would really like to actually only allocate 64KB of memory, not 128KB and then do the alignment manually - far too wasteful. VirtualAlloc on windows gives precisely this behavior. Supposedly there's code in SquirrelFish for doing this on just about every platform, but I haven't managed to locate it. Is there a space efficient way to allocate 64KB on a 64KB boundary in POSIX? Failing that, in Linux?

  • DataGridView Cell Validating only when 'Enter' is pressed

    - by Eldad
    Hi, I want to validate and commit the value entered in the DataGridViewCell ONLY when the user presses the 'Enter' key. If the users presses any other key or mouse button (Arrow keys, Pressing a different cell using the mouse...), I want the behavior to be similar to the 'ESC' key: Move the focus to the new cell and revert the edited cell value to its previous value.

  • How to force Json.Net to put an integer value into a string field?

    - by Earlz
    Hello, in using Json.Net I have a class like this class Foo{ public string name; public string value; } and I have a JSON string that looks like this: [{"name": "some name","value": "1"}] The problem with this is that Json.Net detects "1" as being an integer(due to ambiguities with JSON) and will refuse to put it into the string value of Foo How can I override this behavior so that it will put the string "1" into value?

  • Check item in CheckedListBox without selecting

    - by Dmi
    How can I allow the user to click to check an item in CheckedListBox in one click? The default behaviour is the first click selects the item, the second click allows you to toggle the check. I don't want to toggle the check on select either, I'm looking for the behavior of the ListView control where I can click directly on check boxes to toggle them without selecting their items first.

  • Mysterious constraints problem with SQL Server 2000

    - by Ramon
    Hi all I'm getting the following error from a VB NET web application written in VS 2003, on framework 1.1. The web app is running on Windows Server 2000, IIS 5, and is reading from a SQL server 2000 database running on the same machine. System.Data.ConstraintException: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. at System.Data.DataSet.FailedEnableConstraints() at System.Data.DataSet.EnableConstraints() at System.Data.DataSet.set_EnforceConstraints(Boolean value) at System.Data.DataTable.EndLoadData() at System.Data.Common.DbDataAdapter.FillFromReader(Object data, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.Common.DbDataAdapter.FillFromCommand(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet) The problem appears when the web app is under a high load. The system runs fine when volume is low, but when the number of requests becomes high, the system starts rejecting incoming requests with the above exception message. Once the problem appears, very few requests actually make it through and get processed normally, about 2 in every 30. The vast majority of requests fail, until a SQL Server restart or IIS reset is performed. The system then start processing requests normally, and after some time it starts throwing the same error. The error occurs when a data adapter runs the Fill() method against a SELECT statement, to populate a strongly-typed dataset. It appears that the dataset does not like the data it is given and throws this exception. This error occurs on various SELECT statements, acting on different tables. I have regenerated the dataset and checked the relevant constraints, as well as the table from which the data is read. Both the dataset definition and the data in the table are fine. Admittedly, the hardware running both the web app and SQL Server 2000 is seriously outdated, considering the numbers of incoming requests it currently receives. The amount of RAM consumed by SQL Server is dynamically allocated, and at peak times SQL Server can consume up to 2.8 GB out of a total of 3.5 GB on the server. At first I suspected some sort of index or database corruption, but after running DBCC CHECKDB, no errors were found in the database. So now I'm wondering whether this error is a result of the hardware limitations of the system. Is it possible for SQL Server to somehow mess up the data it's supposed to pass to the dataset, resulting in constraint violation due to, say, data type/length mismatch? I tried accessing the RowError messages of the data rows in the retrieved dataset tables but I kept getting empty strings. I know that HasErrors = true for the datatables in question. I have not set the EnableConstraints = false, and I don't want to do that. Thanks in advance. Ray

  • How do I list Clearcase versions without the Fully-qualified verison?

    - by Luciano
    In Clearcase: I'm trying to find the names of all files in the current view without a specific label. So far I've come up with the following: cleartool find -cview -all -version '\!lbtype(LABEL_1)' -print But this ends up displaying the filenames with the "@@/main/BRANCH1/SUBBRANCH" appended to the end, and I really want just the filename. I've tried adding a -short, but the find command doesn't like that option, and I can't find an option in the manuals to change the behavior.
