  • Override a static library's global function

    - by Jason Madux
    Not sure if this question belongs here or on SO, but posting here for now :) I'm trying to override a global function defined in "StaticLib" for my iOS application but the compiler keeps giving me the duplicate symbol error. Relevant code: #import "MyApplication.h" #import "StaticLib.h" NSData* getAllData() { NSLog(@"myGetAllData"); return nil; } @implementation MyApplication ... @end I've looked into Apple's runtime library but that all seems to be class-oriented. Any suggestions or is it just not possible to override global functions from static libraries?

  • Reflection & Parameters in C#

    - by Jim
    Hello, I'm writing an application that runs "things" to a schedule. Idea being that the database contains assembly, method information and also the parameter values. The timer will come along, reflect the method to be run, add the parameters and then execute the method. Everything is fine except for the parameters. So, lets say the method accepts an ENUM of CustomerType where CustomerType has two values of CustomerType.Master and CustomerType.Associate. EDIT I don't the type of parameter that will be getting passed in. ENUM used as an example END OF EDIT We want to run Method "X" and pass in parameter "CustomerType.Master". In the database, there will be a varchar entry of "CustomerType.Master". How do I convert the string "CustomerType.Master" into a type of CustomerType with a value of "Master" generically? Thanks in advance, Jim

  • Why not write all tests at once when doing TDD? [closed]

    - by RichK
    Possible Duplicate: Why not write all tests at once when doing TDD? The Red - Green - Refactor cycle for TDD is well established and accepted. We write one failing unit test and make it pass as simply as possible. What are the benefits to this approach over writing many failing unit tests for a class and make them all pass in one go. The test suite still protects you against writing incorrect code or making mistakes in the refactoring stage, and code coverage should be just as high, so what's the harm? Sometimes it's easier to write all the tests first as a form of 'brain dump' to quickly write down all the expected behavior in one go.

  • Will taking two years off for school in a related field destroy a mid level development career?

    - by rsteckly
    Hi, I know some people have asked about getting back into programming after a break and this is a potential duplicate. I just am in a position where I can go back to school for a graduate degree in Stat/Applied Math. But I'm very worried about the impact it will have on my career and ability to find a job afterwards. I have 3 years experience in .NET on top of a couple of years in PHP. Right now, I'm a senior software engineer. Do you think taking two years off to do math is going to dramatically hurt my marketability?

  • How do i set Savepoints for Linq to SQL and use "NO" ExecuteCommand ?

    TransactionScope TransactionABC = new TransactionScope(); try { context.Connection.Open(); { context.ExecuteCommand("insert into test (test) values (1)") context.SubmitChanges(); context.ExecuteCommand("savepoint test"); context.ExecuteCommand("insert into test (test) values (2)") context.SubmitChanges(); context.ExecuteCommand("rollback to test"); } TransactionABC.Complete(); TransactionABC.Dispose(); } catch (Exception ec) { MessageBox.Show(" ", ec.Message); } finally { context.Connection.Close(); } It works, but only with ExecuteCommand. I want to use a function, because i can't see what happens in the savepoint !

  • Disabled Checkboxes

    - by tonsils
    Hi, Hoping someone can assist or point me in the right direction to another thread/url with regards to disabled checkboxes. I basically have a couple of checkboxes in my form, that are not database items but am retrieving the source value based on a database column. As I do not want the user to be able to change these checboxes, I have disabled these checboxes When I query a record, the form at start-up retrieves the value for the checkbox with no issues. The problem is, when I hit a validation error on my form when the page is submitted, my checkbox values that were originally retrieved as 'Y', i.e checked are now null. Can anyone pls assist with what is going on or a workaround inorder to maintain these values when a validation error occurs. Thanks.

  • SQL Server Reporting Services Format Hours as Hours:Minutes

    - by Frank Schmitt
    I'm writing reports on SQL Server Reporting Server that have a number of hours grouped by, say, user, and a total calculated based on the sum of the values. Currently my query runs a stored proc that returns the hours as in HH:MM format, rather than decimal hours, as our users find that more intuitive. The problem occurs when I try and add up the column using an SSRS expression, because the SUM function isn't smart enough to handle adding up times in this format. Is there any way to: Display a time interval (in minutes or hours) in HH:MM format while having it calculated in decimal form? Or split up and calculate the total of the HH:MM text values to arrive at a total as an expression? I'd like to avoid having to write/run a second query just to get the total.

  • what is a fast way to output h5py dataset to text?

    - by user362761
    I am using the h5py python package to read files in HDF5 format. (e.g. somefile.h5) I would like to write the contents of a dataset to a text file. For example, I would like to create a text file with the following contents: 1,20,31,75,142,324,78,12,3,90,8,21,1 I am able to access the dataset in python using this code: import h5py f = h5py.File('/Users/Me/Desktop/thefile.h5', 'r') group = f['/level1/level2/level3'] dset = group['dsetname'] My naive approach is too slow, because my dataset has over 20000 entries: # write all values to file for index in range(len(dset)): # do not add comma after last value if index == len(dset)-1: txtfile.write(repr(dset[index])) else: txtfile.write(repr(dset[index])+',') txtfile.close() return None Is there a faster way to write this to a file? Perhaps I could convert the dataset into a NumPy array or even a Python list, and then use some file-writing tool? (I could experiment with concatenating the values into a larger string before writing to file, but I'm hoping there's something entirely more elegant)

  • Teaching java interfaces to absolute beginners: What is a good example? [closed]

    - by mrsteve
    Possible Duplicate: Explaining interfaces to beginning programmers? I searched on stackoverflow and here for a good example to teach java interfaces in a beginners class. I found the following post: http://stackoverflow.com/questions/416331/java-interfaces The Official Java-Tutorial and the references feature examples that are quite good but I would need a very simple example to start with for my class. I don't think the offical tutorial is the best resource for absolute beginners. The students are easily confused, and the most effective example would help. Any pointers or experience in teaching java interfaces?

  • Using an IN clause in Vb.net to save something to the database using SQL

    - by Rob
    I have a textbox and a button on a form. I wish to run a query (in Vb.Net) that will produce a query with the IN Values. Below is an example of my code myConnection = New SqlConnection("Data Source=sqldb\;Initial Catalog=Rec;Integrated Security=True") myConnection.Open() myCommand = New SqlCommand("UPDATE dbo.Recordings SET Status = 0 where RecID in ('" & txtRecID.Text & "') ", myConnection) ra = myCommand.ExecuteNonQuery() myConnection.Close() MsgBox("Done!", _ MsgBoxStyle.Information, "Done") When I enter a single value it works but when I enter values with commas it throws an error: "Conversion failed when converting the varchar value '1234,4567' to data type int." Could someone please help me to solve this or if there is an alternative way? Many Thanks

  • console.log() and google chrome

    - by Lorenzo C
    I'm testing a library and I use console.log() function to visualyze values. There is a strange behaviour of Google Chrome (in other browser like Firefox it doesn't happend). If I try to store strings in Array object when I log them, sometimes values appears undefined. Code example (item.name is a string) var arrayItemsSearch = [item.name]; var itemRedrawName = [item.name]; console.log("arrayItemsSearch: ", arrayItemsSearch); console.log("itemRedrawName: ", itemRedrawName); Firefox output is correct arrayItemsSearch: ["elem[0]"] itemRedrawName: ["elem[0]"] Chrome output is not correct arrayItemsSearch: [undefined × 1] itemRedrawName: ["elem[0]"] Is this a Chrome bug? Or is this beacuse in Javascript strings are immutable objects and so something that I don't understand goes wrong?

  • MySQL - Join as zero if record Not IN

    - by Zurahn
    To explain by example, take two tables, A and B Table A id foo 1 x 2 y 3 z Table B id aid bar 1 3 50 2 1 100 An example join SELECT foo, bar FROM a, b WHERE a.id = b.aid; Garners a result of foo bar z 50 x 100 What I would like to do is get all values of foo and for any instances where there isn't a corresponding bar value, return 0 for that column. My best guess was something along the lines of SELECT foo, bar AS br FROM a, b WHERE a.id = b.aid OR a.id NOT IN (SELECT aid FROM b); But that returns duplicates and non-zero values for bar. Possible?

  • How to iterate over every property of an object in javascript?

    - by OverloadUT
    Is there a way to iterate over every property of an object using the Prototype JavaScript framework? Here's the situation: I am getting an AJAX response in JSON that looks something like this: {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}} If I evaluate that json response in to a variable response, I want to be able to iterate over each property in the response.barobj object to see which indexes are true and which are false. Prototype has both Object.keys() and Object.values() but oddly seems to not have a simple Object.each() function! I could take the results of Object.keys() and Object.values() and cross-reference the other as I iterate through one, but that is such a hack that I am sure there is a proper way to do it!

  • How does thumbnail preview in Ubuntu differ from that of Windows? [closed]

    - by Forbidden Overseer
    Possible Duplicate: How does Ubuntu know what file type a file without extension is I thought this question might get a better response in AskUbuntu, as it seems to have more to do with Ubuntu than Windows at a glance. Let's say I have a foo.mkv file. Thumbnail previews work in both Windows 7 and Ubuntu. When I change the filename to anything random like foo.bar or when I remove the extension itself (making it just foo), Nautilus shows thumbnails normally like if it can recognize what type of files they are - without looking at file extension. This however, doesn't happen in Windows 7. Windows starts asking me things like which application I want to use to open that file as soon as I remove file extension (forget thumbnails...) etc. So, How does this thumbnail preview work in Windows 7 and Ubuntu? What makes Ubuntu recognize files "out of the box" unlike Windows 7?

    Possible Duplicate: How do I install Google Chome on legacy 7.10 computer? I am trying to get google-chrome to work on Ubuntu 7.10.

  • Is age a factor when looking for internships? [closed]

    - by user786362
    Possible Duplicate: Is it ever too old to learn how to become a programmer? I'm 30 years old going back to school for a 2nd degree in Computer Science. I will be transferring to my local state university this fall and would like to know if my age will be a factor when applying for internships. I have already read a few threads about age and careers: Is it too late to start your career as a programmer at the age of 30? Does it matter that you started developing at 26? While it is reassuring to know that people are getting entry-level programming jobs at 30+, what about internships? Should I even bother with bigger companies like Google, Microsoft, or Apple? I know we have laws against age-discrimination but lets not pretend we live in a perfect world where everyone follows the rules.

  • Pending and Approval process

    - by zen
    So let's say I have a DB table with 8 columns, one is a unique auto-incrementing used as ID. So I have a page that pulls in the info for each row based on query string ID. I want to give my users the ability to propose changes. Kinda like a wiki setup. So I was thinking I should just have another duplicate table or maybe database altogether (without the auto-incrementing column and maybe with a date edited column) that keeps all proposed changes in queue and then when I approve them, the script can move the row from the proposed DB to the real DB. Does this sound good or is there a better process for this?

  • EntityFramework: Access dabase-column using user defined Type

    - by Nils
    I "inherited" an old Database where dates are stored as Int32 values (times too, but dates shall suffice for this example) i.e. 20090101 for Jan. 1st 2009. I can not change the schema of this database because it is still accessed by the old programs. However I want to write a new program using EF as the O/R-M. Now I'd love to have DateTime-Values in my Model. Is there a way to write a custom type and use this as a Type in the EF-Model. Something like a Type "OldDate" with properties: DatabaseValue : Int23 Value : DateTime (specifying the date-part whereas the time-part is always 0:00:00) Is something like this possible with the EF-Model ?

  • Problems inserting file data into sqlite database using python

    I'm trying to open an image file in python and add that data to an sqlite table.

  • building a pairwise matrix in scipy/numpy in Python from dictionaries

    - by user248237
    I have a dictionary whose keys are strings and values are numpy arrays, e.g.: data = {'a': array([1,2,3]), 'b': array([4,5,6]), 'c': array([7,8,9])} I want to compute a statistic between all pairs of values in 'data' and build an n by x matrix that stores the result. Assume that I know the order of the keys, i.e. I have a list of "labels": labels = ['a', 'b', 'c'] What's the most efficient way to compute this matrix? I can compute the statistic for all pairs like this: result = [] for elt1, elt2 in itertools.product(labels, labels): result.append(compute_statistic(data[elt1], data[elt2])) But I want result to be a n by n matrix, corresponding to "labels" by "labels". How can I record the results as this matrix? thanks.
