  • CSS Position:Absolute with relative adjustment

    - by Gidiyo
    I am trying to do a vertical dropdown menu. This is my code .menu li:hover>ul{ position:absolute; display:inline; left:120px; top:100px;} I use position: Absolute to remove the sub-menu from the table, once the menu gets hovered. It appears that, if I do not indicate top or left property. The sub-menu will displayed relatively. Now I need to adjust the position relatively but seems that only the left property works. So my sub-menu left position is 120px relatively away from its original position. But the top is 100px away from the top of the window, rather then to the original position. How do I move the list up relative to it original position? I cant use position:relative because I need the sub-menu to be remove from the table.

  • What's the straightforward way to implement one to many editing in list_editable in django admin?

    - by Nate Pinchot
    Given the following models: class Store(models.Model): name = models.CharField(max_length=150) class ItemGroup(models.Model): group = models.CharField(max_length=100) code = models.CharField(max_length=20) class ItemType(models.Model): store = models.ForeignKey(Store, on_delete=models.CASCADE, related_name="item_types") item_group = models.ForeignKey(ItemGroup) type = models.CharField(max_length=100) Inline's handle adding multiple item_types to a Store nicely when viewing a single Store. The content admin team would like to be able to edit stores and their types in bulk. Is there a simple way to implement Store.item_types in list_editable which also allows adding new records, similar to horizontal_filter? If not, is there a straightforward guide that shows how to implement a custom list_editable template? I've been Googling but haven't been able to come up with anything. Also, if there is a simpler or better way to set up these models that would make this easier to implement, feel free to comment.

  • Trappings MySQL Warnings on Calls Wrapped in Classes -- Python

    - by chernevik
    I can't get Python's try/else blocks to catch MySQL warnings when the execution statements are wrapped in classes. I have a class that has as a MySQL connection object as an attribute, a MySQL cursor object as another, and a method that run queries through that cursor object. The cursor is itself wrapped in a class. These seem to run queries properly, but the MySQL warnings they generate are not caught as exceptions in a try/else block. Why don't the try/else blocks catch the warnings? How would I revise the classes or method calls to catch the warnings? Also, I've looked through the prominent sources and can't find a discussion that helps me understand this. I'd appreciate any reference that explains this. Please see code below. Apologies for verbosity, I'm newbie. #!/usr/bin/python import MySQLdb import sys import copy sys.path.append('../../config') import credentials as c # local module with dbase connection credentials #============================================================================= # CLASSES #------------------------------------------------------------------------ class dbMySQL_Connection: def __init__(self, db_server, db_user, db_passwd): self.conn = MySQLdb.connect(db_server, db_user, db_passwd) def getCursor(self, dict_flag=True): self.dbMySQL_Cursor = dbMySQL_Cursor(self.conn, dict_flag) return self.dbMySQL_Cursor def runQuery(self, qryStr, dict_flag=True): qry_res = runQueryNoCursor(qryStr=qryStr, \ conn=self, \ dict_flag=dict_flag) return qry_res #------------------------------------------------------------------------ class dbMySQL_Cursor: def __init__(self, conn, dict_flag=True): if dict_flag: dbMySQL_Cursor = conn.cursor(MySQLdb.cursors.DictCursor) else: dbMySQL_Cursor = conn.cursor() self.dbMySQL_Cursor = dbMySQL_Cursor def closeCursor(self): self.dbMySQL_Cursor.close() #============================================================================= # QUERY FUNCTIONS #------------------------------------------------------------------------------ def runQueryNoCursor(qryStr, conn, dict_flag=True): dbMySQL_Cursor = conn.getCursor(dict_flag) qry_res =runQueryFnc(qryStr, dbMySQL_Cursor.dbMySQL_Cursor) dbMySQL_Cursor.closeCursor() return qry_res #------------------------------------------------------------------------------ def runQueryFnc(qryStr, dbMySQL_Cursor): qry_res = {} qry_res['rows'] = dbMySQL_Cursor.execute(qryStr) qry_res['result'] = copy.deepcopy(dbMySQL_Cursor.fetchall()) qry_res['messages'] = copy.deepcopy(dbMySQL_Cursor.messages) qry_res['query_str'] = qryStr return qry_res #============================================================================= # USAGES qry = 'DROP DATABASE IF EXISTS database_of_armaments' dbConn = dbMySQL_Connection(**c.creds) def dbConnRunQuery(): # Does not trap an exception; warning displayed to standard error. try: dbConn.runQuery(qry) except: print "dbConn.runQuery() caught an exception." def dbConnCursorExecute(): # Does not trap an exception; warning displayed to standard error. dbConn.getCursor() # try/except block does catches error without this try: dbConn.dbMySQL_Cursor.dbMySQL_Cursor.execute(qry) except Exception, e: print "dbConn.dbMySQL_Cursor.execute() caught an exception." print repr(e) def funcRunQueryNoCursor(): # Does not trap an exception; no warning displayed try: res = runQueryNoCursor(qry, dbConn) print 'Try worked. %s' % res except Exception, e: print "funcRunQueryNoCursor() caught an exception." print repr(e) #============================================================================= if __name__ == '__main__': print '\n' print 'EXAMPLE -- dbConnRunQuery()' dbConnRunQuery() print '\n' print 'EXAMPLE -- dbConnCursorExecute()' dbConnCursorExecute() print '\n' print 'EXAMPLE -- funcRunQueryNoCursor()' funcRunQueryNoCursor() print '\n'

  • What can cause a persistent "Reload the page to get source for" error in firebug?

    - by ripper234
    I'm trying to debug the javascript of a specific page, and I keep seeing Reload the page to get source for page.htm in Firebug. On Chrome, I'm mostly able to debug the js, but sometimes I also get a blank page. What can cause such issues? I believe I always see a blank page in Chrome if I reload while the JS console is open. If I open a new Chrome tab, load the page, and then open the JS console, everything is ok. The page I'm debugging is on a localhost server (Play Framework server), although I have seen this on other pages occasionally. This only happens with inline javascript ... js that is linked from the page is displayed fine.

  • Facebook/Youtube Like Multiple Items Select

    - by bradenkeith
    Before we continue: It can't be a predefined list. I need it sort of like this: http://loopj.com/tokeninput/demo.html ... A jQuery plugin that allows the user to type a string of words, press enter, and it makes it a block of text, from there they can press the X to get rid of it, or type more key words into the input area. I've found many things that do this, but all are pulling information from a predefined list of choices.

  • Iterate through every file in one directory

    - by Andrew
    How do i write a loop in ruby so that I can execute a block of code on each file? I'm new to ruby, and I've concluded that the way to do this is a do each loop. The ruby file will be executed from a different directory than the directory I want to loop through. I've tried the Dir.foreach and I couldn't get it to work.

  • Programming Language Choices for High Integrity Systems

    - by Finbarr
    What programming languages are a good choice for High Integrity Systems? An example of a bad choice is Java as there is a considerable amount of code that is inaccessible to the programmer. I am looking for examples of strongly typed, block structured languages where the programmer is responsible for 100% of the code, and there is as little interference from things like a JVM as possible. Compilers will obviously be an issue. Language must have a complete and unambiguous definition.

  • Client server architecture question

    - by Shane Fulmer
    I am working on a client server system, and am running into issues where multiple clients are executing an action at the same time. We are able to solve this by locking on the critical section of code, which ensures that the first client will complete the action before the second client enters the code block. My question is this: our server is also clustered, so multiple instances of the server itself can exist, which recreates the same problem as before. How could we solve this problem? Thanks!

  • "Ambiguous template specialization" problem

    - by Setien
    I'm currently porting a heap of code that has previously only been compiled with Visual Studio 2008. In this code, there's an arrangement like this: template <typename T> T convert( const char * s ) { // slow catch-all std::istringstream is( s ); T ret; is >> ret; return ret; } template <> inline int convert<int>( const char * s ) { return (int)atoi( s ); } Generally, there are a lot of specializations of the templated function with different return types that are invoked like this: int i = convert<int>( szInt ); The problem is, that these template specializations result in "Ambiguous template specialization". If it was something besides the return type that differentiated these function specializations, I could obviously just use overloads, but that's not an option. How do I solve this without having to change all the places the convert functions are called?

  • Determine if a string contains only alphanumeric characters (or a space)

    - by dreamlax
    I'm learning C++ and I am writing a function that determines whether a string contains only alphanumeric characters and spaces. I suppose I am effectively testing whether it matches the regular expression ^[[:alnum:] ]+$ but without using regular expressions. I have seen a lot of algorithms revolve around iterators, so I tried to find a solution that made use of iterators, and this is what I have: #include <algorithm> static inline bool is_not_alnum_space(char c) { return !(isalpha(c) || isdigit(c) || (c == ' ')); } bool string_is_valid(const std::string &str) { return find_if(str.begin(), str.end(), is_not_alnum_space) == str.end(); } Is there a better solution, or a “more C++” way to do this?

  • C# multiple asynchronous HttpRequest with one callback

    - by aepheus
    I want to make 10 asynchronous http requests at once and only process the results when all have completed and in a single callback function. I also do not want to block any threads using WaitAll (it is my understanding that WaitAll blocks until all are complete). I think I want to make a custom IAsyncResult which will handle multiple calls. Am I on the right track? Are there any good resources or examples out there that describe handling this?

  • Base64 Encoded Data - DB or Filesystem

    - by Marty
    I have a new program that will be generating a lot of Base64 encoded audio and image data. This data will be served via HTTP in the form of XML and the Base64 data will be inline. These files will most likely break 20MB and higher. Would it be more efficient to serve these files directly from the filesystem or would it be feasible to store the data in a MySQL database? Caching will be set up but overall unnecessary because it is likely that this data will be purged shortly after it is created and served. i know that storing binary data in the DB is frowned upon in most circumstances but since this will all be character data I want to see what the consensus is. As of now, I am leaning toward storing them in the filesystem for efficiency reasons but if it is feasible to store them in a database it would be much easier to manage the data.

  • Widget -what to do and what not

    - by mkoso
    I would like to make a html/js widget that people can add to their blogs, sites etc. I have never made widgets before so I would like to hear what should be done and what not. For example, how do I make the styling? Inline, own css file or what is the best practise? I believe i cant use head and body stuff in it. What about h1, h2 etc? Do they screw the website that has the widget or can i use them? If you have any good tips I would like to hear those. Thanks.

  • How to read from CSS files with jQuery

    - by Neurofluxation
    Ok, I have a HTML page with jQuery included. I have a CSS file with a good load of lines in, I would like to read all styles for a given element from the external CSS file... Not the inline styles... I have the following code (which looks like it should work...): var styleProperties= {}; var getCssProperties = ['width', 'margin', 'height']; for (c=0;i<=returnStyleProps.length;c++) { styleProperties[returnStyleProps[c]] = $('div#container').css(returnStyleProps[c]); alert(styleProperties); } alert(styleProperties); But this only seems to alert: "[Object Object]" Any ideas you clever people?

How do I do the following in C#: Initial state: semaphore counter = 0 Thread 1: // Block until semaphore is signalled semaphore.Wait(); // wait until semaphore counter is 1 Thread 2: // Allow thread 1 to run: semaphore.Signal(); // increments from 0 to 1 It's not a mutex because there is no critical section, or rather you can say there is an infinite critical section. So what is it?
