String[] expression = {""}; //globally declared as empty somewhere in the code below, I am trying to assign a string to it. expression[0] = "Hi"; I keep getting the following error... 12-08 22:12:19.063: E/AndroidRuntime(405): java.lang.ArrayIndexOutOfBoundsException Can someone help me with this.. Can we access the index 0, directly as i am doing? Actual Code ::: static int x = 0; // global declaration String[] assembledArray = {""}; // global declaration assembleArray(strSubString, expression.charAt(i)); //Passing string to the method //Method Implementation private void assembleArray(String strSubString, char charAt) { // TODO Auto-generated method stub assembledArray[x] = strSubString; assembledArray[x+1] = String.valueOf(charAt); x = x+2; }

  • Cannot open simplest mac application

    - by streetpc
    I created a very simple app, which is only a wrapper of a shell script (so that I can select this script in application selectors, like startup apps). I try to launch it and yesterday it worked, but today I changed the executable script's content and name (with something that perfeclty works in a shell script launched in the Terminal) and it will only display a Finder-iconed dialog saying Cannot open the application because it is not supported on this kind of Mac. I restored the previous script (content/name) but I still get the error! Same when re-bundling the app from scratch, or completely changing the bundle identifier… If I try to open it in the Terminal using open My.app, I get The application cannot be opened because it has an incorrect executable format. But when I executes directly the Contents/MacOS/Script, it allways works (iwth both contents). Also, it is displayed with correct icon and meta-information in the Finder (so I guess the Info.plist is understood). The app's file tree is: Contents/ Info.plist MacOS/ Script (executable bit set, works when launched directly) PkgInfo Resources/ AppIcon.icns Here is the Info.plist content: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>CFBundleExecutable</key> <string>Script</string> <key>CFBundleIconFile</key> <string>AppIcon</string> <key>CFBundleIdentifier</key> <string>asdf.ScriptApp</string> <key>CFBundleInfoDictionaryVersion</key> <string>6.0</string> <key>CFBundleName</key> <string>My script</string> <key>CFBundlePackageType</key> <string>APPL</string> <key>CFBundleShortVersionString</key> <string>1.0</string> <key>CFBundleSignature</key> <string>????</string> <key>CFBundleVersion</key> <string>1</string> <key>LSMinimumSystemVersion</key> <string>10.4</string> </dict> </plist> And the PkgInfo file only contains APPL????. I tested the Script with a simple echo "ok" and echo "ok" >/tmp/test (plus #!/bin/sh header). So my questions are: * Is there some kind of validity caching for applications ? based on what ? how do I flush it ? * Where does this message come from ? I tried to google it but all I get is a page talking about 32/64 bits Java…

  • Split string on non-alphanumerics in PHP? Is it possible with php's native function?

    - by Jehanzeb.Malik
    I was trying to split a string on non-alphanumeric characters or simple put I want to split words. The approach that immediately came to my mind is to use regular expressions. Example: $string = 'php_php-php php'; $splitArr = preg_split('/[^a-z0-9]/i', $string); But there are two problems that I see with this approach. It is not a native php function, and is totally dependent on the PCRE Library running on server. An equally important problem is that what if I have punctuation in a word Example: $string = 'U.S.A-men's-vote'; $splitArr = preg_split('/[^a-z0-9]/i', $string); Now this will spilt the string as [{U}{S}{A}{men}{s}{vote}] But I want it as [{U.S.A}{men's}{vote}] So my question is that: How can we split them according to words? Is there a possibility to do it with php native function or in some other way where we are not dependent? Regards

  • How to compute a unicode string which bidirectional representation is specified?

    - by valdo
    Hello, fellows. I have a rather pervert question. Please forgive me :) There's an official algorithm that describes how bidirectional unicode text should be presented. http://www.unicode.org/reports/tr9/tr9-15.html I receive a string (from some 3rd-party source), which contains latin/hebrew characters, as well as digits, white-spaces, punctuation symbols and etc. The problem is that the string that I receive is already in the representation form. I.e. - the sequence of characters that I receive should just be presented from left to right. Now, my goal is to find the unicode string which representation is exactly the same. Means - I need to pass that string to another entity; it would then render this string according to the official algorithm, and the result should be the same. Assuming the following: The default text direction (of the rendering entity) is RTL. I don't want to inject "special unicode characters" that explicitly override the text direction (such as RLO, RLE, etc.) I suspect there may exist several solutions. If so - I'd like to preserve the RTL-looking of the string as much as possible. The string usually consists of hebrew words mostly. I'd like to preserve the correct order of those words, and characters inside those words. Whereas other character sequences may (and should) be transposed. One naive way to solve this is just to swap the whole string (this takes care of the hebrew words), and then swap inside it sequences of non-hebrew characters. This however doesn't always produce correct results, because actual rules of representation are rather complex. The only comprehensive algorithm that I see so far is brute-force check. The string can be divided into sequences of same-class characters. Those sequences may be joined in random order, plus any of them may be reversed. I can check all those combinations to obtain the correct result. Plus this technique may be optimized. For instance the order of hebrew words is known, so we only have to check different combinations of their "joining" sequences. Any better ideas? If you have an idea, not necessarily the whole solution - it's ok. I'll appreciate any idea. Thanks in advance.

  • How to convert a video via ffmpeg to an mp4 format that will stream and/or download to iPhone and Bl

    - by Yegor
    I have a site where people upload videos, which are converted to .flv format. Simple. I wanted to also convert to an mp4 format that will "stream" to an iphone and blackberry, or allowed to be downloaded to either, for later viewing. Can someone post a working ffmpeg line to accomplish this task? Closest I got was this (which doesn't work) ffmpeg -i in.avi -f mp4 -vcodec libx264 -maxrate 1000 -qmin 3 -qmax 5 -bufsize 4096 -g 300 -acodec libfaac -s 480x320 -ab 128k -qscale 7 out.mp4

  • C#: The input stream is not a valid binary format.

    - by Mcoroklo
    I have a problem with deserializing in C#/ASP.NET, which gives the exact error: The input stream is not a valid binary format. The starting contents (in bytes) are: 41-41-45-41-41-41-44-2F-2F-2F-2F-2F-41-51-41-41-41 ... What I am trying to do I have a structure with 3 classes. I have a class A which is a base class, and then class B and C which are derived from A. I am trying to store random types of B and C in the database using LINQ to SQL, in a column with the type VARCHAR(MAX). I cannot use BINARY as the length is around 15.000. My code... Error is in the LAST codeblock C# Code in Business layer- Storing a record private void AddTraceToDatabase(FightTrace trace) { MemoryStream recieverStream = new MemoryStream(); MemoryStream firedStream = new MemoryStream(); MemoryStream moveStream = new MemoryStream(); BinaryFormatter binaryFormatter = new BinaryFormatter(); binaryFormatter.Serialize(recieverStream,trace.Reciever); binaryFormatter.Serialize(firedStream,trace.FiredBy); binaryFormatter.Serialize(moveStream,trace.Move); string reciever = Convert.ToBase64String(recieverStream.ToArray()); string fired = Convert.ToBase64String(firedStream.ToArray()); string move = Convert.ToBase64String(moveStream.ToArray()); this.dataAccess.AddFightTrace(trace.TraceType.ToString(),reciever,move,fired,trace.DateTime,this.FightId); } C# Code in Data access layer - Storing a record public void AddFightTrace(string type, string reciever, string Move, string firedBy, DateTime firedAt, int fightid) { GameDataContext db = new GameDataContext(); dbFightTrace trace = new dbFightTrace(); trace.TraceType = type; trace.Reciever = reciever; trace.Move = Move; trace.FiredBy = firedBy; trace.FiredAt = firedAt; trace.FightId = fightid; db.dbFightTraces.InsertOnSubmit(trace); db.SubmitChanges(); } C# Code getting the entry in the database public List<dbFightTrace> GetNewTraces(int fightid, DateTime lastUpdate) { GameDataContext db = new GameDataContext(); var data = from d in db.dbFightTraces where d.FightId==fightid && d.FiredAt > lastUpdate select d; return data.ToList(); } C# Factory, converting from LINQ to SQL class to my objects THIS IS HERE THE ERROR COMES public FightTrace CreateTrace(dbFightTrace trace) { TraceType traceType = (TraceType) Enum.Parse(typeof(TraceType), trace.TraceType); BinaryFormatter formatter = new BinaryFormatter(); System.Text.UTF8Encoding enc = new System.Text.UTF8Encoding(); MemoryStream recieverStream = new MemoryStream(enc.GetBytes(trace.Reciever)); recieverStream.Position = 0; MemoryStream firedStream = new MemoryStream(enc.GetBytes(trace.FiredBy)); firedStream.Position = 0; MemoryStream movedStream = new MemoryStream(enc.GetBytes(trace.Move)); movedStream.Position = 0; // THE NEXT LINE HERE CAUSES THE ERROR NPC reciever = formatter.Deserialize(recieverStream) as NPC; Player fired = formatter.Deserialize(firedStream) as Player; BaseAttack attack = formatter.Deserialize(movedStream) as BaseAttack; FightTrace t = new FightTrace(traceType,reciever,attack,fired); t.TraceId = trace.FightTraceId; t.DateTime = trace.FiredAt; return t; } So the error happends when the first Deserialize method is run, with the above error. I have tried several things but I am quite lost on this one.. Thanks! :-)

  • C# & C++, runtime error when call C++ dll from C#

    - by 5YrsLaterDBA
    I have written a C++ wrapper DLL for C# to call. The DLL was tested and worked fine with my C++ test program. now integrated with C#, I got runtime error and crashed. Cannot use debugger to see more details. The C++ side has only one method: #ifdef DLLWRAPPERWIN32_EXPORTS #define DLLWRAPPERWIN32_API __declspec(dllexport) #else #define DLLWRAPPERWIN32_API __declspec(dllimport) #endif #include "NB_DPSM.h" extern "C" { DLLWRAPPERWIN32_API int WriteGenbenchDataWrapper(string fileNameToAnalyze, string parameterFileName, string baseNameToSaveData, string logFileName, string& message) ; } in the C# side, there is a definition, [DllImport("..\\..\\thirdParty\\cogs\\DLLWrapperWin32.dll")] public static extern int WriteGenbenchDataWrapper(string fileNameToAnalyze, string parameterFileName, string baseNameToSaveData, string logFileName, ref string message); and a call: string msg = ""; int returnVal = WriteGenbenchDataWrapper(rawDataFileName, parameterFileName, outputBaseName, logFileName, ref msg); I guess there must be something wrong with the last parameter of the function. string& in C++ should be ref string in C#?

  • Will I use HtmlDocument even I want to parse the HTML string using HtmlAglityPack ?

    - by skhan
    Hi everyone, I'm working in C#. I'm trying to extract the first instance of img tag from a HTML string (which is actually a post data). This is my code: private string GrabImage(string htmlContent) { String firstImage; HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument(); htmlDoc.LoadHtml(htmlContent); HtmlAgilityPack.HtmlNode imageNode = htmlDoc.DocumentNode.SelectSingleNode("//img"); if (imageNode != null) { return firstImage = imageNode.ToString(); } else return firstImage=" "; } But it gets null in htmlDoc, will I use the HtmlDocument type even if I'm trying to parse the HTML from a string ? P.S btw is it the correct way of grabbing the first instance of image tag from my HTML string?

  • oracle index for string column - does format of data affects quality of index?

    - by Jayan
    We have following type of "Unique ID" column for many tables in the database (Oracle). It is a string with following format <randomnumber>-<ascendingnumber>-<machinename> So we have some thing like this U1234-12345-NBBJD U1234-12346-NBBJD U1234-12347-NBBJD U1234-12348-NBBJD U1234-12349-NBBJD The UID value is unique, we have unique index on them. Does the following format is more efficient than above for index scans? NBBJD-U1234-12345 NBBJD-U1234-12346 NBBJD-U1234-12347 NBBJD-U1234-12348 NBBJD-U1234-12349

  • WCF methods sharing a dictionary

    - by YeomansLeo
    I'm creating a WCF Service Library and I have a question regarding thread-safety consuming a method inside this library, here is the full implementation that I have until now. namespace WCFConfiguration { [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, ConcurrencyMode = ConcurrencyMode.Single)] public class ConfigurationService : IConfigurationService { ConcurrentDictionary<Tuple<string,string>, string> configurationDictionary = new ConcurrentDictionary<Tuple<string,string>, string>(); public void Configuration(IEnumerable<Configuration> configurationSet) { Tuple<string, string> lookupStrings; foreach (var config in configurationSet) { lookupStrings = new Tuple<string, string>(config.BoxType, config.Size); configurationDictionary.TryAdd(lookupStrings, config.RowNumber); } } public void ScanReceived(string boxType, string size, string packerId = null) { } } } Imagine that I have a 10 values in my configurationDictionary and many people want to query this dictionary consuming ScanReceived method, are those 10 values be shared for each of the clients that request ScanReceived? Do I need to change my ServiceBehavior? The Configuration method is only consumed by one person by the way.

  • mature, powerful Perl library to support text/string operation ?

    - by user534009
    Do we have a mature, powerful Perl library to support text/string operation ? for example, if I need to trim a string, I need to write a function like below. Then question is, do we have an existing API so that I can import and call it ? just like StringUtils.trim(s) in Apache Common Lang. Thanks. sub trim($) { my $string = shift; $string =~ s/^\s+//; $string =~ s/\s+$//; return $string; }

  • How do I manipulate the format on a DataGridView that is bound to a Data Source?

    - by Jack Johnstone
    I´m using SQL Server 2005 and Visual Studio 2008, C#. In the data source (the SQL Server data table) I use the DateTime format mm/dd/yyyy, however, in a forms overview (DataGridView) users would like to see a completely other format, with year, week number and day number of week (yyww,d) which is in string format. I´ve created an algorithm for the transformation between values (date to weekday), but can I populate the affected cells with yyww,d (string) instead of mm/dd/yyyy (DateTime)? This is what I´ve been testing out, without success (and note, it´s on the last line the problem becomes obvious, as the cell value won´t accept a string on runtime - it still wants to be a DateTime...) private void DataGridViewQueryFindRequests_CellFormatting( object sender, DataGridViewCellFormattingEventArgs e) { string weekAndDay = ""; DataGridViewCell cell = DataGridViewQueryFindRequests.Rows[e.RowIndex].Cells[e.ColumnIndex]; if (cell.ColumnIndex == 13 && cell.Value == null) mEmptyRow = true; if ((cell.ColumnIndex == 14 || cell.ColumnIndex == 15) && !mEmptyRow) { weekAndDay = ClassWeeksAndDates.dateToWeekNumber(Convert.ToDateTime(cell.Value)); cell.ValueType = typeof(string); cell.Value = weekAndDay; } }
