• Changing color of a row in dropdown list

  - by Judy

  is it possible to change "selector" color in drop-down list? <select name="select" style="background-color: #ff0000"> <option style="background-color: #ff0000" value="1">Red</option> <option style="background-color: #ffffff" value="2">Green</option> <option style="background-color: #0000ff" value="3">Blue</option> </select> I tried in above style but it didn't worked. I know with javascript getting document.getElementById('text').style.color='red' can set the color. But is it possible in html to set the colors?

• Paginating requests to an API

  - by user332912

  I'm consuming (via urllib/urllib2) an API that returns XML results. The API always returns the total_hit_count for my query, but only allows me to retrieve results in batches of, say, 100 or 1000. The API stipulates I need to specify a start_pos and end_pos for offsetting this, in order to walk through the results. Say the urllib request looks like "http://someservice?query='test'&start_pos=X&end_pos=Y". If I send an initial 'taster' query with lowest data transfer such as http://someservice?query='test'&start_pos=1&end_pos=1 in order to get back a result of, for conjecture, total_hits = 1234, I'd like to work out an approach to most cleanly request those 1234 results in batches of, again say, 100 or 1000 or... This is what I came up with so far, and it seems to work, but I'd like to know if you would have done things differently or if I could improve upon this: hits_per_page=1000 # or 1000 or 200 or whatever, adjustable total_hits = 1234 # retreived with BSoup from 'taster query' base_url = "http://someservice?query='test'" startdoc_positions = [n for n in range(1, total_hits, hits_per_page)] enddoc_positions = [startdoc_position + hits_per_page - 1 for startdoc_position in startdoc_positions] for start, end in zip(startdoc_positions, enddoc_positions): if end total_hits: end = total_hits print "url to request is:\n ", print "%s&start_pos=%s&end_pos=%s" % (base_url, start, end) p.s. I'm a long time consumer of StackOverflow, especially the Python questions, but this is my first question posted. You guys are just brilliant.

• how to find last version no from a list<> in C#

  - by Rohit

  I have a entity class RenderingTemplates. Inside this i have a property List which holds all versions of rendering template. RenderingTemplateVersion has a property VersionName which stores version name as "Version 1.0". I am creating a new version and want to find last version no.so that i can append it by 1 and make new VersionName as "Version 2.0". To accomplish this i have LatestVersion = template.RenderingTemplateVersionList.OrderByDescending(e => e.VersionName.Split(new char[] { ' ', '.' })[1]).First() LatestVersion is a integer. How to convert this to integer.Please help or suggest some other way.

• Utilizing a Queue

  - by Nathan

  I'm trying to store records of transactions all together and by category for the last 1, 7, 30 or 360 days. I've tried a couple things, but they've brutally failed. I had an idea of using a queue with 360 values, one for each day, but I don't know enough about queue's to figure out how that would work. Input will be an instance of this class: class Transaction { public string TotalEarned { get; set; } public string TotalHST { get; set; } public string TotalCost { get; set; } public string Category { get; set; } } New transactions can occur at any time during the day, and there could be as many as 15 transactions in a day. My program is using a plain text file as external storage, but how I load it depends on how I decide to store this data. What would be the best way to do this?

• Getting list of all existing vtables.

  - by Patrick

  In my application I have quite some void-pointers (this is because of historical reasons, application was originally written in pure C). In one of my modules I know that the void-pointers points to instances of classes that could inherit from a known base class, but I cannot be 100% sure of it. Therefore, doing a dynamic_cast on the void-pointer might give problems. Possibly, the void-pointer even points to a plain-struct (so no vptr in the struct). I would like to investigate the first 4 bytes of the memory the void-pointer is pointing to, to see if this is the address of the valid vtable. I know this is platform, maybe even compiler-version-specific, but it could help me in moving the application forward, and getting rid of all the void-pointers over a limited time period (let's say 3 years). Is there a way to get a list of all vtables in the application, or a way to check whether a pointer points to a valid vtable, and whether that instance pointing to the vtable inherits from a known base class?

Would the .click() event be triggered in this case as well?

• Is it faster to loop through a Python set of number or a set of letters?

  - by Scott Bartell

  Is it faster to loop through a Python set of numbers or a Python set of letters given that each set is the exact same length and each item within each set is the same length? Why? I would think that there would be a difference because letters have more possible characters [a-zA-Z] than numbers [0-9] and therefor would be more 'random' and likely affect the hashing to some extent. numbers = set([00000,00001,00002,00003,00004,00005, ... 99999]) letters = set(['aaaaa','aaaab','aaaac','aaaad', ... 'aaabZZ']) # this is just an example, it does not actually end here for item in numbers: do_something() for item in letters: do_something() where len(numbers) == len(letters) Update: I am interested in Python's specific hashing algorithm and what happens behind the scenes with this implementation.

• GQL Query with __key__ in List of KEYs

  - by bossylobster

  In the GQL reference [1], it is encouraged to use the IN keyword with a list of values, and to construct a Key from hand the GQL query SELECT * FROM MyModel WHERE __key__ = KEY('MyModel', 'my_model_key') will succeed. However, using the code you would expect to work: SELECT * FROM MyModel WHERE __key__ IN (KEY('MyModel', 'my_model_key1'), KEY('MyModel', 'my_model_key2')) in the Datastore Viewer, there is a complaint of "Invalid GQL query string." What is the correct way to format such a query? [1] http://code.google.com/appengine/docs/python/datastore/gqlreference.html PS I know there are more efficient ways to do this in Python (without constructing a GQL query) and using the remote_api, but each call to the remote_api counts against quota. In an environment where quota is not (necessarily) free, quick and dirty queries are very helpful.

• Python sort 2-D list by time string

  - by Mark Kennedy

  How do I sort a multi dimensional list like this based on a time string? The sublists can be of different sizes (i.e. 4 and 5, here) I want to sort by comparing the first time string in each sublist (sublist[-4]) x = (['1513', '08:19PM', '10:21PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['0690', '07:25AM', '09:19AM', 1, 4], ['0201', '08:50AM', '10:50AM', 1, 4], ['1166', '04:35PM', '06:36PM', 1, 4], ['0845', '05:40PM', '07:44PM', 1, 4], ['1267', '07:05PM', '09:07PM', 1, 4], ['1513', '08:19PM', '10:21PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['8772', '0159', '12:33PM', '02:43PM', 1, 5], ['0888', '0570', '09:42PM', '12:20AM', 1, 5], ['2086', '2231', '04:10PM', '06:20PM', 1, 5]) The sorted result would be sortedX = (['0690', '07:25AM', '09:19AM', 1, 4], ['0201', '08:50AM', '10:50AM', 1, 4], ['1166', '04:35PM', '06:36PM', 1, 4], ['0845', '05:40PM', '07:44PM', 1, 4], ['1267', '07:05PM', '09:07PM', 1, 4], ['1513', '08:19PM', '10:21PM', 1, 4], ['1513', '08:19PM', '10:21PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['1290', '09:45PM', '11:43PM', 1, 4], ['8772', '0159', '12:33PM', '02:43PM', 1, 5], ['2086', '2231', '04:10PM', '06:20PM', 1, 5], ['0888', '0570', '09:42PM', '12:20AM', 1, 5]) I tried the following: sortedX = sorted(x, key=lambda k : k[-4]) #k[-4] is the first time string and it works but it doesn't respect the sublist size ordering

• Using Custom Generic Collection faster with objects than List

  - by Kaminari

  I'm iterating through a List<> to find a matching element. The problem is that object has only 2 significant values, Name and Link (both strings), but has some other values which I don't want to compare. I'm thinking about using something like HashSet (which is exactly what I'm searching for -- fast) from .NET 3.5 but target framework has to be 2.0. There is something called Power Collections here: http://powercollections.codeplex.com/, should I use that? But maybe there is other way? If not, can you suggest me a suitable custom collection?

  Looking for some best practices of UI list on iPhone which has item add/modify/delete functions. Please refer to some sample codes or articles to build user friendly interface. The main application is tab bar application and one of the tabs supposed to show item management. The item itself consisting of 3 text items, first one can be label, it's short, the rest if it's not terribly complicated I would like to show below with small font or show when user taps on item entering edit mode... Not sure how to design all this and which views to use.

• Possible to convert list of #defines into strings (C++)

  - by brandonC

  Suppose I have a list of #defines in a header file for an external library. These #defines represent error codes returned from functions. I want to write a conversion function that can take as an input an error code and return as an output a string literal representing the actual #define name. As an example, if I have #define NO_ERROR 0 #define ONE_KIND_OF_ERROR 1 #define ANOTHER_KIND_OF_ERROR 2 I would like a function to be able to called like int errorCode = doSomeLibraryFunction(); if (errorCode) writeToLog(convertToString(errorCode)); And have convertToString() be able to auto-convert that error code without being a giant switch-case looking like const char* convertToString(int errorCode) { switch (errorCode) { case NO_ERROR: return "NO_ERROR"; case ONE_KIND_OF_ERROR: return "ONE_KIND_OF_ERROR"; ... ... ... I have a feeling that if this is possible, it would be possible using templates and metaprogramming, but that would only work the error codes were actually a type and not a bunch of processor macros. Thanks

• Mixing LINQ to SQL with properties of objects in a generic list

  I am trying to accomplish something like this query: var query = from a in DatabaseTable where listOfObjects.Any(x => x.Id == a.Id) select a; Basically, I want to filter the results where a.Id equals a property of one of the objects in the generic list "listOfObjects". I'm getting the error "Local sequence cannot be used in LINQ to SQL implementation of query operators except the Contains() operator." Any ideas on how to filter this in an easily readable way using "contains" or another method? Thanks in advance.

• Determining where to animate the map given a list of GeoPoints

  - by Itsik

  My android application loads some markers on an overlay onto a MapView. The markers are placed based on a dynamic list of GeoPoints. I want to move the map center and zoom into the area with most items. Naively, I can calculate the superposition of all the points, but I would like to remove the points that are very far from the mass of points from the calculation. Is there a known way to calculate this ? (e.g. probability, statistics .. ?)

• Enum : get the keys list

  - by Damien MATHIEU

  Hello, I'm not a java developer. But I'm currently taking a look at Android applications development so I'm doing a bit of nostalgy, doing some java again after not touching it for three years. I'm looking forward using the "google-api-translate-java" library. In which there is a Language class. It's an enum allowing to provide the language name and to get it's value for Google Translate. I can easily get all the values with : for (Language l : values()) { // Here I loop on one value } But what I'd want to get is a list of all the keys names (FRENCH, ENGLISH, ...). Is there something like a "keys()" method that'd allow me to loop through all the enum's keys ?

• Efficient and accurate way to compact and compare Python lists?

  - by daveslab

  Hi folks, I'm trying to a somewhat sophisticated diff between individual rows in two CSV files. I need to ensure that a row from one file does not appear in the other file, but I am given no guarantee of the order of the rows in either file. As a starting point, I've been trying to compare the hashes of the string representations of the rows (i.e. Python lists). For example: import csv hashes = [] for row in csv.reader(open('old.csv','rb')): hashes.append( hash(str(row)) ) for row in csv.reader(open('new.csv','rb')): if hash(str(row)) not in hashes: print 'Not found' But this is failing miserably. I am constrained by artificially imposed memory limits that I cannot change, and thusly I went with the hashes instead of storing and comparing the lists directly. Some of the files I am comparing can be hundreds of megabytes in size. Any ideas for a way to accurately compress Python lists so that they can be compared in terms of simple equality to other lists? I.e. a hashing system that actually works? Bonus points: why didn't the above method work?

• Java - Optimize finding a string in a list

  - by Mark

  I have an ArrayList of objects where each object contains a string 'word' and a date. I need to check to see if the date has passed for a list of 500 words. The ArrayList could contain up to a million words and dates. The dates I store as integers, so the problem I have is attempting to find the word I am looking for in the ArrayList. Is there a way to make this faster? In python I have a dict and mWords['foo'] is a simple lookup without looping through the whole 1 million items in the mWords array. Is there something like this in java? for (int i = 0; i < mWords.size(); i++) { if ( word == mWords.get(i).word ) { mLastFindIndex = i; return mWords.get(i); } }
