  • Segmentation fault problem (C)

    - by user228938
    I have a struct named Game with an array of levels, defined like this: typedef struct { Level levels[x]; } Game; When I compile the code, if x is 1, 2 or 3, the program runs normally. If it's any other value (4, for instance), I get a segmentation fault. I'm not accessing the array anywhere. Main is something like this at the moment (commented everything except the initialization): int main (...) { Game g; return 0; } Any clue of what this might be? Thanks in advance.

  • google search rankings and trends api

    - by Drakkhen
    I'm looking to find an api or program or interface to get the following information. I would like to see the amount of times a particular search term was used and its /weekly/monthly/yearly breakdown along with its rank in a particular page. I've found googlesearchpositionfinder.com and google.com/trends but i have 5000 terms to search for by hand is not happening. I've also found www.juiceanalytics.com/openjuice/programmatic-google-trends-api but it doesn't allow me to do a break down for a period of 2 years. Basically i'm trying to create a ranking of search phrases, the weeks(period) they were more popular and how a particular site(e.g urban dictionary) showed up in googles search rankings for the terms.

    - by maxsap
    Hello, I have made an application that records from the phones microphone using the AudioRecord and 16-bit encoding, and I am able to playback the recording. For some compatibility reason I need to use 8-bit encoding, but when I try to run the same program using that encoding I keep getting an Invalid Audio Format. my code is : int bufferSize = AudioRecord.getMinBufferSize(11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_8BIT); AudioRecord recordInstance = new AudioRecord( MediaRecorder.AudioSource.MIC, 11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_8BIT, bufferSize); Any one knows what is the problem? according to the documentation AudioRecord is capable of 8-bit encoding. thanks in advanced maxsap.

  • How do I get the CoreData Debug argument to output to the console?

    - by radesix
    According to Apple documentation on debugging Core Data it says we should be able to pass an argument to the application which will output the SQL core data sends to SQLite. I have gone into the arguments tab of my executable in XCode and specified the argument: -com.apple.CoreData.SQLDebug 1 However, I see no SQL in the console. I then tried to use this parameter in the CoreDataBooks application provided by Apple just in case there was some other issue in MY program. Even in Apple's example I get no SQL output in the console. Am I doing something wrong? Is Apple's documentation wrong? Should I be looking someplace other than the console? Has anyone else had success with this argument?

  • How Android 2.2 interacting with Flash 10.1?

    - by zxcat
    Hi! I'm searched adobe and android developers sites, but can't find any details on this. Is it possible to use Flash as a part of my app? E.g. like a widget/GUI element? Or it's integrated in browser only and can't be simple accessible? I know, Adobe AIR apps are supported as standalone .apk. So it must be some API/SDK (from Google) to connect with Flash player. Is there any details, how to program it (more clear: launch swf from my app and interact with it)? Thank you!

  • Saving Excel Spreadsheet using Interop C#

    - by Wesley
    static void Main() { Application excelapp = new Application(); Workbook book = excelapp.Workbooks.Open(@"C:\HWYFAB.xlsx", 0, false, 5, "", "", false, XlPlatform.xlWindows , "", true, false, 0, true, false, false); Worksheet sheet = (Worksheet)book.Sheets[1]; Range cell = (Range)sheet.Cells[3, 2]; Console.WriteLine(cell.Text); cell.ClearContents(); book.Close(true, "HWYFAB.xlsx", false); excelapp.Quit(); } This program runs and exits as expected. It does print the correct value that's in cell B3 to the console. When closing it asks if I want to replace the existing file. I click yes. When I open the spreadsheet in Excel, the value is still in cell B3 despite the cell.ClearContents(). Any thoughts?

  • Reading TCP Sequence Number Before Sending a Packet

    - by Sadeq Dousti
    I'm writing a C/C++ client-server program under Linux. Assume a message m is to be sent from the client to the server. Is it possible for the client to read the TCP sequence number of the packet which will carry m, before sending m? In fact, I'd like to append this sequence number to m, and send the resulting packet. (Well, things are more complicated, but let's keep it that simple. In fact, I'd like to apply authentication info to this sequence number, and then append it to m.) Moreover, is it possible for the server to read the TCP sequence number of the packet carrying m?

  • Custom Control Events in C#

    - by pm_2
    I'm trying to create a custom control and need to raise an event from it. The idea is to raise an event at the end of the click event (OnAfterClick). I found one or two tutorials on doing this, but am clearly missing a step somewhere; I have the following. In the control: public class AfterClickEventArgs : EventArgs { ... } public partial class MyButton : CommandButton { public delegate void AfterClickEvnt(object sender, AfterClickEventArgs e); public event AfterClickUpdatedEvnt AfterClick; } protected override void OnClick(EventArgs e) { ... Processing here ... AfterClickEventArgs myArgs = new AfterClickEventArgs(); AfterClick(this, newArgs); } In the program using the control: In InitializeComponent(): this.MyButton.AfterClick += new System.EventHandler(this.cmdMyButton_Click); This line is giving me a compile error (cmdMyButton_Click does exist). It tells me: Cannot implicitly convert type 'System.EventHandler' to 'Namespace.MyButton.AfterClick' Can anyone tell me what I'm missing, or misunderstanding about this, please?

  • copying the contents of an image file

    - by Ganesh
    I am designing an image decoder and as a first step I tried to just copy the using c. i.e open the file, and write its contents to a new file. Below is the code that I used. while((c=getc(fp))!=EOF) fprintf(fp1,"%c",c); where fp is the source file and fp1 is the destination file. The program executes without any error, but the image file(".bmp") is not properly copied. I have observed that the size of the copied file is less and only 20% of the image is visible, all else is black. When I tried with simple text files, the copy was complete. Do you know what the problem is?

  • BATCH - wait for executable to finish before starting next result

    - by user3697573
    I'm pretty much a noob at this, so any help is appreciated. I'm trying to run the video transcoding executable REDline on all .R3D files in a given folder. REDline only accepts single files, which is the issue. I finally got it to search recursively for the files I need, but my problem is the search function passes the next result to REDline before the first one is finished transcoding. I have the search results that need to run in a variable inside REDline. Here's the code: for /r D:\folder\ %%a in (*) do ( "C:/Program Files/REDCINE-X PRO 64-bit/REDLine.exe" --exportPreset "Prores_Intermediate" --i "%%~dpnxa" --useRSX 2 --masterRMDFolder "" -s 0 -e 95 ) After about .7 seconds, REDline reports 'received stop message from client'. I don't think this is a REDline error, as I have been able to transcode single files successfully. Thanks.

  • How do I implement an higher lower game algorithm?

    - by lazorde
    The computer will guess a player’s number between 1 and 100. After each guess the human player should respond “higher”, “lower” or “correct”. Your program should be able to guess the player’s number in no more than 7 tries. Begin by explaining the game to the player, telling him/her to think of a number between 1 and 100. Make the computer do what you would normally do to guess a number in a certain range. Allow the user to respond with “higher”, “lower”, or “correct” after each computer guess. Output the number of tries it took the computer to guess the number. Make the game as user friendly as you can.

  • Write the longest possible loop.

    - by Abhay
    Hello Group, Recently I was asked this question in a technical discussion. What is the longest possible loop that can be written in a programming language? This loop has to be as long as possible and yet not an infinite loop and should not end-up crashing the program (Recursion etc...) I honestly did not know how to attack this problem, so I asked him if is it practically possible. He said using some computer science concepts, you can arrive at a hypothetical number which may not be practical but nevertheless it will still not be infinite. Anyone here; knows how to analyse / attack this problem. P.S. Choosing some highest limit for a type that can store the highest numerical value is apparently not an answer. Thanks in advance,

  • [C#] How to create a constructor of a class that return a collection of instances of that class?

    - by codemonkie
    My program has the following class definition: public sealed class Subscriber { private subscription; public Subscriber(int id) { using (DataContext dc = new DataContext()) { this.subscription = dc._GetSubscription(id).SingleOrDefault(); } } } ,where _GetSubscription() is a sproc which returns a value of type ISingleResult<_GetSubscriptionResult> Say, I have a list of type List<int> full of 1000 ids and I want to create a collection of subscribers of type List<Subscriber>. How can I do that without calling the constructor in a loop for 1000 times? Since I am trying to avoid switching the DataContext on/off so frequently that may stress the database. TIA.

  • What are the exact versions of stuff you had to install in order to be able to step-debug a Scala pr

    - by Alex R
    How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence the second part of my question, which is really the most important part: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

  • Convert Yes/No/Null from SQL to True/False in a DataTable

    - by Scott Chamberlain
    I have a Sql Database (which I have no control over the schema) that has a Column that will have the varchar value of "Yes", "No", or it will be null. For the purpose of what I am doing null will be handled as No. I am programming in c# net 3.5 using a data table and table adapter to pull the data down. I would like to directly bind the column using a binding source to a check box I have in my program however I do not know how or where to put the logic to convert the string Yes/No/null to boolean True/False; Reading a null from the SQL server and writing back a No on a update is acceptable behavior. Any help is greatly appreciated. EDIT -- This is being developed for windows.

  • Torrents: Can I protect my software by sending wrong bytes?

    - by Martijn Courteaux
    Hi, It's a topic that everyone interests. How can I protect my software against stealing, hacking, reverse engineering? I was thinking: Do my best to protect the program for reverse engineering. Then people will crack it and seed it with torrents. Then I download my own cracked software with a torrent with my own torrent-software. My own torrent-software has then to seed incorrect data (bytes). Of course it has to seed critical bytes. So people who want to steal my software download my wrong bytes. Just that bytes that are important to startup, saving and loading data, etc... So if the stealer download from me (and seed it later) can't do anything with it, because it is broken. Is this idea relevant? Maybe, good torrent-clients check hashes from more peers to check if the packages (containing my broken bytes) I want to seed are correct or not? Thanks

  • How can I mix command line arguments and filenames for <> in Perl?

    - by Jimmeh
    Consider the following silly Perl program: $firstarg = $ARGV[0]; print $firstarg; $input = <>; print $input; I run it from a terminal like: perl myprog.pl sample_argument And get this error: Can't open sample_argument: No such file or directory at myprog.pl line 5. Any ideas why this is? When it gets to the < is it trying to read from the (non-existent) file, "sample_argument" or something? And why?

  • C++ detecting end of file

    - by xbonez
    I have a C++ program that is reading in info from a file, that stores info seperated by "$$$$". An example of how the file looks is: abc bcd $$$$ def $$$$ qwe gfh $$$$ How can I detect the file has ended, without using the eof() function? I have it set like this, getline(sin,temp) if (temp=="$$$$") { } After reading the last set of four dollars, how can I check the next line to ensure another set of data isn't beginning, and that the file has ended? If the file has indeed ended, I plan on using a boolean flag to terminate the while loop.

  • Mouse move and thread

    - by bsebi
    When I move the mouse over the window, the program runs much faster (cc. 3 times). This is a real time webcam .Net/Mono application running on a MacBook. On Windows works perfect. Is this maybe a power saving function of the laptop? The code: Thread t = new Thread(Foo); t.Priority = ThreadPriority.Highest; // I've tried without priority too, doesn't matter t.Start(); ... void Foo() { while (true) { ++k; // then write k to the window somehow } }

  • Complexity in using Binary search and Trie

    - by user121196
    given a large list of alphabetically sorted words in a file,I need to write a program that, given a word x, determines if x is in the list. Preprocessing is ok since I will be calling this function many times over different inputs. priorties: 1. speed. 2. memory I already know I can use (n is number of words, m is average length of the words) 1. a trie, time is O(log(n)), space(best case) is O(log(n*m)), space(worst case) is O(n*m). 2. load the complete list into memory, then binary search, time is O(log(n)), space is O(n*m) I'm not sure about the complexity on tri, please correct me if they are wrong. Also are there other good approaches?

  • C# move file as soon as it becomes available.

    - by m0s
    Hi, I need to accomplish the following task: Attempt to move a file. If file is locked schedule for moving as soon as it becomes available. I am using File.Move which is sufficient for my program. Now the problems are that: 1) I can't find a good way to check if the file I need to move is locked. I am catching System.IO.IOException but reading other posts around I discovered that the same exception may be thrown for different reasons as well. 2) Determining when the file gets unlocked. One way of doing this is probably using a timer/thread and checking the scheduled files lets say every 30 seconds and attempting to move them. But I hope there is a better way using FileSystemWatcher. This is a .net 3.5 winforms application. Any comments/suggestions are appreciated. Thanks for attention.

  • How do I include a newline in a text message sent as email from an ASP.Net application?

    - by Tim Goodman
    I have an ASP.Net Application that sends text messages to mobile phones. It does this by sending an email. For instance, if your phone number is 555-555-5555 and your wireless carrier is Verizon, you can send an email to [email protected] and it will show up as a text message. I want to be able to include a newline in the body of the message. How do I do this? Also please note that my ASP.Net program gets the message from a database (MS SQL Server) so what I really need to know is what characters to include in the message body when I store it in my database. I already tried \n but it just showed up in the text message as \n
