• iOS development license and itunes connect

  - by Andreas

  New to iOS development and everything with the license is driving me nuts. So i got a few questions. I have a developer account but not a license yet. If i buy a iOS developer license for $99, that license is then stuck to my account? Can one developer account have multiple iTunes Connect accounts or is it stuck to one? Before i started to read up on stuff my account got added to a company's iTunes Connect account. If i then buy a license would i be stuck to just develop to that company or is it possible to change? I want to develop for my self and also one specific company. Can i use the same licence or do i need two? Can you have multiple licenses/certifications or whatever its called in Xcode? Is the iOS Developer Program both for development and distribution?

• What information about me and my system do compilers add to executeables?

  - by I can't tell you my name.

  I'm currently using Microsoft Visual Studio 2010. If we say that we give 10 different people a copy of MSVC 10 and a short C++ Hello, World listing. They all create a new project using exactly the same settings, add a new cpp file with the Hello, World program and compile it. Do they all get the exactly same binary? If not, what are the exact differences? What information about my system does MSVC add to my executeable? Paranoia!

• Reading PGP key information

  - by calccrypto

  can someone show a description of the information of what a pgp looks like if only the descriptions were there but not the actual information? something like (i dont remember if the values are correct): packet-type[4 bits], total length in bytes[16 bits], packet version type [4 bits], creation-time[32 bits], encryption-algorithm[8 bits], ...,etc,etc ive tried to understand rfc4880, but its tedious and confusing. so far, i am think i have extracted the 4 i wrote above, but i cant seem to get the rest of the information out. can anyone help? i know i can just find some pgp program, but the whole point of this is to allow me to learn how those programs work in the first place

• Assigning a variable of a struct that contains an instance of a class to another variable

  - by xport

  In my understanding, assigning a variable of a struct to another variable of the same type will make a copy. But this rule seems broken as shown on the following figure. Could you explain why this happened? using System; namespace ReferenceInValue { class Inner { public int data; public Inner(int data) { this.data = data; } } struct Outer { public Inner inner; public Outer(int data) { this.inner = new Inner(data); } } class Program { static void Main(string[] args) { Outer p1 = new Outer(1); Outer p2 = p1; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); p1.inner.data = 2; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); p2.inner.data = 3; Console.WriteLine("p1:{0}, p2:{1}", p1.inner.data, p2.inner.data); Console.ReadKey(); } } }

• C# Custom Control Properties load before Load and arrays are empties

  - by Wildhorn

  Hello, I made a custom control with custom properties. When I modify these properties in the "Form.cs [Design]", I need stuff to happens (it fill some arrays and modify the look of the control), so I call a function within the "set" of the property. All of this works good. My problem is that when I run the program with my custom control, it seems that properties "set" is called, which will call the function, but then, my arrays seems now to have lost all their values and the function use these arrays, but now because they are all empty, it crashes due to NullException blahblahblah. It also seems that properties "set" is called before the control Load (which I guess is called only when it is added to my Form, and not when the Form load). So question is, why does my arrays become empty once I try to run the Form and is there an event that is called before that when the Form load? Thanks

• Adobe Acrobat API - How to skip opening password protected PDFs?

  - by Ryan

  Hi all, I've been using Delphi and the Adobe Acrobat 9 API. I'm simply opening a PDF and printing it, followed by closing it without saving anything. I'm having an issue while opening some PDFs though. If the PDF is password protected the Open method displays Adobe's "Input password" prompt. My application is running in an automated fashion, and therefor cannot proceed beyond this password prompt until somebody clicks cancel. I've been looking for something that will either notify me that the file is password protected prior to opening it, or a parameter or something that will skip password protected files. I need my program to assume it cannot open any passworded PDF. Does anyone know enough about the Acrobat API to provide any assistance here? Thank you, Ryan

• Screen capture during testing

  - by Edwward

  This is an application for reviewing performance tests. Simple in concept, tricky to describe. Picture: 1) Recording interactions with a WPF program so the inputs can be played back. 2) Playing the inputs back while doing a continuous screen capture. 3) Capturing wall time as well as continuous CPU percentages during playback. 4) Repeating steps (2) and (3) lots of times. 5) Writing the relevant stuff out to files/db. 6) Reading it and putting it all in a fancy UI for easy review/analysis. The killer for me is (2). I could use some guidance on a good, possibly commercial, screen capture SDK. I would also welcome the news that my whole problem already has a solution. And of course any thoughts on the overall idea would also be great. Thanks. Ed

• c arrays: setting size dynamically?

  - by user336994

  Hello, I am new to C programming. I am trying to set the size of the array using a variable but I am getting an error: Storage size of 'array' isn't constant !! 01 int bound = bound*4; 02 static GLubyte vertsArray[bound]; I have noticed that when I replace bounds (within the brackets on line 02) with the number say '20', the program would run with no problems. But I am trying to set the size of the array dynamically ... Any ideas why I am getting this error ? thanks much,

• What should be proper location for sqlit3 database file?

  - by Elliot Chen

  Hi, Everyone: I'm using a sqlite3 database to store app's data. Instead of building a database within program, I introduced an existing db file: 'abc.sqlite' into my project and put it under my 'Resources' folder. So, I think this db file should be inside of 'bundle', so at my init function, I used following statement to read it out: NSString *path = [[NSBundle mainBundle] pathForResource:@"abc" ofType:"sqlite"]; if(sqlite3_open([path UTF8String], &database) != SQLITE_OK) ... It's ok that this db can be opened and data can be retrieved from it. BUT, someone told me that it's better to copy this db file into user folder: such as 'Document'. So, my question is: is it ok to use this db from main bundle directly or copy it to user folder then use that copy. Which is better? Thank you very much!

• What's the best way to write a maintainable web scraping app?

  - by Benj

  I wrote a perl script a while ago which logged into my online banking and emailed me my balance and a mini-statement every day. I found it very useful for keeping track of my finances. The only problem is that I wrote it just using perl and curl and it was quite complicated and hard to maintain. After a few instances of my bank changing their webpage I got fed up of debugging it to keep it up to date. So what's the best way of writing such a program in such a way that it's easy to maintain? I'd like to write a nice well engineered version in either Perl or Java which will be easy to update when the bank inevitably fiddle with their web site.

• VB.NET: Can the .EXE built by VS2005 be deployed as a standalone EXE?

  - by Craig Johnston

  VB.NET: Can the .EXE built by VS2005 be deployed as a standalone EXE? When I change the mode in VS2005 to "Release" and build the solution, the bin\Release directory then contains the solution .EXE file, but also a .pdb, vshost.exe and .xml file. What are these extra files and are they necessary? I copied the .exe file to another machine and it executed properly, but there was a significant delay when it first executed - thereafter it was like any other program. What is the reason for this, and can it be helped? Is it because the other 3 files in the Release folder are not there with it?

• Testing for the existence of a field in a class

  - by Brett

  Hi, i have a quick question. I have a 2D array that stores an instance of a class. The elements of the array are assigned a particular class based on a text file that is read earlier in the program. Since i do not know without looking in the file what class is stored at a particular element i could refer to a field that doesn't exist at that index (referring to appearance when an instance of temp is stored in that index). i have come up with a method of testing this, but it is long winded and requires a second matrix. Is there a function to test for the existence of a field in a class? class temp(): name = "default" class temp1(): appearance = "@"

• How to tell process id within Python

  - by R S

  Hey, I am working with a cluster system over linux (www.mosix.org) that allows me to run jobs and have the system run them on different computers. Jobs are run like so: mosrun ls & This will naturally create the process and run it on the background, returning the process id, like so: [1] 29199 Later it will return. I am writing a Python infrastructure that would run jobs and control them. For that I want to run jobs using the mosrun program as above, and save the process ID of the spawned process (29199 in this case). This naturally cannot be done using os.system or commands.getoutput, as the printed ID is not what the process prints to output... Any clues? Edit: Since the python script is only meant to initially run the script, the scripts need to run longer than the python shell. I guess it means the mosrun process cannot be the script's "son process". Any suggestions? Thanks

• C#: How to gracefully pass multiple conditions to Equals()

  - by Roy

  I'm new to C#, and I'm trying to write a program that selects file types from a FileInfo list. So far I have something along the lines of: List<FileInfo> files = new List<FileInfo>(); IEnumerable<FileInfo> result = files.Where(f=>f.Extension.Equals(".jpg", StringComparison.InvariantCultureIgnoreCase)|| f.Extension.Equals(".gif", StringComparison.InvariantCultureIgnoreCase) ); etc Obviously I'm not happy with this solution, but I don't know how to do this otherwise in a single call. What's the better way to go about it?

• Stopping pirates

  - by Pirate for Profit

  Okay, what do I do to stop pirates? Obviously a callhome to internet service. We are considering making some major aspects be dependent on a web service of some sort. Memory offsets and cracking. If I like rand randomly to allocate empty memory on the heap, would this throw off the crackers? I hacked some memory shit for EverQuest back in the dizzay but don't really know much about this. Registry on windows, etc., I know theres ways to identify the computer. That's easily spoofed with hex editor, but if I jumble up the strings in the program would that help? I need to know that + real ideas. I want the serials of their sound cards. Any other ideas?

• Facebook Open Graph without a browser

  - by Hellnar

  Hello, For a middleware system with internet (which works inside a set-top box) I want to develop a primitive Facebook interface where users can type their user-names and password, showing their latest notification, messages and other casual stuff on the TV screen by using the recent Facebook Graph API. This middleware program uses Java ME to run programs (such as this simple facebook app) and it can connect to internet however it doesn't have a real web browser. Without browser it can connect to any url to retrieve the JSON response however I am not sure how to achieve authentication without a real browser. Under this circumstances, is it possible Facebook authentication? If you think so, what approach would you suggest ? Thanks

• Python Profiling In Windows, How do you ignore Builtin Functions

  - by Tim McJilton

  I have not been capable of finding this anywhere online. I was looking to find out using a profiler how to better optimize my code, and when sorting by which functions use up the most time cumulatively, things like str(), print, and other similar widely used functions eat up much of the profile. What is the best way to profile a python program to get the user-defined functions only to see what areas of their code they can optimize? I hope that makes sense, any light you can shed on this subject would be very appreciated.

• "derivative work" and the consumption of web services

  - by yodaj007

  From the Wowhead Terms of Service: "Intellectual Property Rights The Service and any necessary software used in connection with the Service ("Software") contain proprietary and confidential information that is protected by applicable intellectual property and other laws. You agree not to modify, rent, lease, loan, sell, distribute or create derivative works based on the Service or the Software, in whole or in part." Does this mean that I can't write a program to consume a web service being published by the writers of this TOS? I find it kind of scary that I even have to ask this question. The wikipedia article on "derivative works" isn't very conclusive.

• Import Data from text file into sql DB using CSLA

  - by New Developer

  I am trying to import data from ~ Delimited Text file into SQL Server using CSLA. My text file has 92,000 records in it. Here are the issues i am having with the import When i create a BusinnessListBase .new and add all my records to it, it gives me a "Out of meory exception". So to fix it i create a new bussinessbase object and save it. this works fine and is much faster too. It takes 15 minutes I have to run my program again and check for any changes and hence update them, this is where it takes too much time. Is there any alternative way to speed up my import?

• I need to do a BASICE For Loop algorithm for a java Pyramid

  - by user1665119

  Question 2. USE THE FOR LOOP. Design and write an algorithm that will read a single positive number from the keyboard and will then print a pyramid out on the screen. The pyramid will need to be of a height equal in lines to the number inputted by the operator. Your program is not to test for negative numbers, nor is it to cater for them. For your test, use the number 7. If you would like to take the problem further, try 18 and watch what happens. Example input: 4 Example output: 1 121 12321 1234321

• MD5 hash differences between Python and other file hashers

  - by Sam

  I have been doing a bit of programming in Python (still a n00b at it) and came across something odd. I made a small program to find the MD5 hash of a filename passed to it on the command line. I used a function I found here on SO. When I ran it against a file, I got a hash "58a...113". But when I ran Microsoft's FCIV or the md5sum.py in \Python26\Tools\Scripts\, I get a different hash, "591...ae6". The actual hashing part of the md5sum.py in Scripts is m = md5.new() while 1: data = fp.read(bufsize) if not data: break m.update(data) out.write('%s %s\n' % (m.hexdigest(), filename)) This looks functionally identical to the code in the function given in the other answer... What am I missing? (This is my first time posting to stackoverflow, please let me know if I am doing it wrong.)

• Why can't I insert record with foreign key in a single server request?

• valgrind - ignore glibc functions?

  - by Jack

  Is it possible to tell valgrind to ignore some set of libraries? Specifically glibc libraries.. Actual Problem: I have some code that runs fine in normal execution. No leaks etc. When I try to run it through valgrind, I get core dumps and program restarts/stops. Core usually points to glibc functions (usually fseek, mutex etc). I understand that there might be some issue with incompatible glibc / valgrind version. I tried various valgrind releases and glibc versions but no luck. Any suggestions?
