  • Java Conversion of byte[] into a srting and then back to a byte[]

    - by Sid
    I am working on a proxy server. I am getting data in byte[] which i convert into a string to perform certain operations. Now when i convert this new string back into a byte [] it causes unkonw problems. So mainly its like i need to know how to correctly convert a byte[] into a string and then back into a byte[] again. I tried to just convert the byte[] to string and then back to byte[] again (to make sure thats its not my operations that are causing problems). So its like: // where reply is a byte[] String str= new String(reply,0, bytesRead); streamToClient.write(str.getBytes(), 0, bytesRead); is not equivalent to streamToClient.write(reply, 0, bytesRead); my proxy works fine when i just send the byte[] without any conversion but when i convert it from byte[] to a string and then back to a byte[] its causes problems. can some one please help? =]

  • Flex: convert VideoPlayer.currentTime to string "00:00:00:000"

    - by numediaweb
    Hi there! what about this one: I want to format the currentTime displayed by a videoPlayer component inside flex, something like : 8230.999 to something like 01:59:59:999 which is "hours:minutes:seconds:milliseconds" I trie different sets of codes but they can't get it to work because currentTime is nor a correct miliseconds time as it adds a floating 3 digit point to seconds; so instead of : 2000ms it outputs 2.000 something people like me just can't understand! thanx for any help :) ### UPDATE I still have problem with milliseconds. here's the current MXML: <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"> <fx:Script> <![CDATA[ protected function convert_clickHandler(event:MouseEvent):void { var val:Number = new Number(inPut.text); //inPut.text = 1000.001 //val = val * 1000; outPut.text = timeFormat(val); } public static function timeFormat(value:Number):String { var milliseconds:Number = value % 1000; var seconds:Number = Math.floor((value/1000) % 60); var minutes:Number = Math.floor((value/60000) % 60); var hours:Number = Math.floor((value/3600000) % 24); var s_miliseconds:String = (milliseconds<10 ?

  • C# Enum Flags Comparison

    - by destructo_gold
    Given the following flags, [Flags] public enum Operations { add = 1, subtract = 2, multiply = 4, divide = 8, eval = 16, } How could I implement an IF condition to perform each operation? In my attempt, the first condition is true for add, eval, which is correct. However the first condition is also true for subtract, eval, which is incorrect. public double Evaluate(double input) { if ((operation & (Operations.add & Operations.eval)) == (Operations.add & Operations.eval)) currentResult += input; else if ((operation & (Operations.subtract & Operations.eval)) == (Operations.subtract & Operations.eval)) currentResult -= input; else currentResult = input; operation = null; return currentResult; } I cannot see what the problem is.

  • How to change the behavior of string objects in web service calls via Windows Communication Foundati

    - by Geri Langlois
    I have third party api's which require string values to be submitted as empty strings. On an asp.net page I can use this code (abbreviated here) and it works fine: public class Customer { private string addr1 = ""; public string Addr1 { get {return addr1;} set {addr1 = value;} } private string addr2 = ""; public string Addr2 { get {return addr2;} set {addr2 = value;} } private string city = ""; public string City { get {return city;} set {city = value;} } } Customer cust = new Customer(); cust.Addr1 = "1 Main St."; cust.City = "Hartford"; int custno = CustomerController.InsertCustomer(cust); The Addr2 field, which was not initialized is still an empty string when inserted. However, using the same code but called it through a web service based on Windows Communication Foundation the Addr2 field is null. Is there a way (or setting) where all string fields, even if uninitialized, would return an empty string (unless, of course, a value was set).

  • Are there any layout comparison / vssetting sharing places?

    - by Wil
    Well, I reinstalled Visual Studio 2008 and did not have a backup of my vssetting file. I did not think it was that important as I had barely customised it, however it just doesn't feel right! The general windows feel correct but When I switch between views (source code, Windows forms, web editor), all the toolbars get muddled up. In the past few years, I have seen so many "post your desktop" type items and I could swear there there would be some "post your IDE", but after looking on Google and several other programming sites, I just can't find one! I don't want this turning in to a post your IDE unless others want to, but can anyone point me to a site where they have done this, or even better - are there any vssetting sharing places where you can download ones made by others?

  • Comparison of collection datatypes in C#

    - by Joel in Gö
    Does anyone know of a good overview of the different C# collection types? I am looking for something showing which basic operations such as Add, Remove, RemoveLast etc. are supported, and giving the relative performance. It would be particularly interesting for the various generic classes - and even better if it showed eg. if there is a difference in performance between a List<T> where T is a class and one where T is a struct. A start would be a nice cheat-sheet for the abstract data structures, comparing Linked Lists, Hash Tables etc. etc. Thanks!

  • How should I call the operation that limit a string's length?

    - by egarcia
    This is a language-agnostic question - unless you count English as a language. I've got this list of items which can have very long names. For aesthetic purposes, these names must be made shorter in some cases, adding dots (...) to indicate that the name is longer. So for example, if article.name returns this: lorem ipsum dolor sit amet I'd like to get this other output. lorem ipsum dolor ... I can program this quite easily. My question is: how should I call that shortening operation? I mean the name, not the implementation. Is there a standard English name for it?

  • Error Downloading Metadata from ASMX Service

    - by michael.lukatchik
    It should be possible (and it looks like it is), but assume I have the following functions in my ASMX web service: [WebMethod(MessageName = "CreateExternalRpt1")] public bool CreateExternalRpt(int iProductId, int iOrderProductId, DateTime dtReportTime, string strReportTitle, string strReportCategory, string strReportPrintType, out string strSnapshot, string strApplicantFirst, string strApplicantLast, string strApplicantMiddle, string strOwnerLast, string strOwnerMiddle, string strOwnerFirst, bool blnCurrentReport, int iOrderId, bool blnFlag, string strCustomerId, string strUserId) { … } [WebMethod(MessageName = "CreateExternalRpt2")] public bool CreateExternalRpt(int iProductId, int iOrderProductId, DateTime dtReportTime, string strReportTitle, string strReportCategory, string strReportPrintType, string strReportSnapshot, string strApplicantFirst, string strApplicantLast, string strApplicantMiddle, string strOwnerLast, string strOwnerMiddle, string strOwnerFirst, bool blnCurrentReport, int iOrderId, bool blnFlag) { … } With both of these functions defined in my web service, my .NET client app can’t download the metadata and instead throws a generic error message “There was an error downloading…”. With one of the above methods removed, the .NET client app can successfully download the metadata. I’ve read that by decorating the WebMethod with a unique name, both functions should be exposed in the service metadata. This isn’t working. What am I missing?

  • iPhone: Error and error handling confusion in comparison.

    - by Mr. McPepperNuts
    NSArray *results = [managedObjectContext executeFetchRequest:request error:&error]; if(results == nil){ NSLog(@"No results found"); searchObj = nil; }else{ if ([[[results objectAtIndex:0] name] caseInsensitiveCompare:passdTextToSearchFor] == 0) { NSLog(@"results %@", [[results objectAtIndex:0] name]); searchObj = [results objectAtIndex:0]; }else { NSLog(@"No results found"); searchObj = nil; } } The code above compares data a user enters to data pulled from a database. If I enter data which is in the database; it works. But if I enter complete gibberish it returns the error below instead of "No results found." *** WebKit discarded an uncaught exception in the webView:shouldInsertText:replacingDOMRange:givenAction: delegate: <NSRangeException> *** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0) The results array being null should be accounted for during the checks in the above code, no?

    - by Reiwoldt
    Hello, I have two comma separated lists:- 36,189,47,183,65,50 65,50,189,47 The question is how to compare the two in classic ASP in order to identify and return any values that exist in list 1 but that don't exist in list 2 bearing in mind that associative arrays aren't available. E.g., in the above example I would need the return value to be 36,183 Thanks

  • More efficient comparison of numbers

    - by Pez Cuckow
    I have an array which is part of a small JS game I am working on I need to check (as often as reasonable) that each of the elements in the array haven't left the "stage" or "playground", so I can remove them and save the script load I have coded the below and was wondering if anyone knew a faster/more efficient way to calculate this. This is run every 50ms (it deals with the movement). Where bots[i][1] is movement in X and bots[i][2] is movement in Y (mutually exclusive). for (var i in bots) { var left = parseInt($("#" + i).css("left")); var top = parseInt($("#" + i).css("top")); var nextleft = left + bots[i][1]; var nexttop = top + bots[i][2]; if(bots[i][1]>0&&nextleft>=PLAYGROUND_WIDTH) { remove_bot(i); } else if(bots[i][1]<0&&nextleft<=-GRID_SIZE) { remove_bot(i); } else if(bots[i][2]>0&&nexttop>=PLAYGROUND_HEIGHT) { remove_bot(i); } else if(bots[i][2]<0&&nexttop<=-GRID_SIZE) { remove_bot(i); } else { //alert(nextleft + ":" + nexttop); $("#" + i).css("left", ""+(nextleft)+"px"); $("#" + i).css("top", ""+(nexttop)+"px"); } } On a similar note the remove_bot(i); function is as below, is this correct (I can't splice as it changes all the ID's of the elements in the array. function remove_bot(i) { $("#" + i).remove(); bots[i] = false; } Many thanks for any advice given!

  • How do I apply a string function to an array?

    - by ggg
    I was fortunate enough to receive this code (flips Lastname, Firstname) from an earlier post. $name = "Lastname, Firstname"; $names = explode(", ", $name); $name = $names[1] . " " . $names[0]; How do I apply the function to each value in an array that is in the form: $ginfo ->$(LastName, FirstName). I tried the code below, but it doesn't work. $name1 =($ginfo->White); $name1 = explode(", ", $name1); $FLw = $name1[1] . " " . $name1[0]; foreach ($name1 as ($ginfo->White)) {return($FLw);}

  • Why is passing a string literal into a char* arguament only sometimes a compiler error?

    - by Brian Postow
    I'm working in a C, and C++ program. We used to be compiling without the make-strings-writable option. But that was getting a bunch of warnings, so I turned it off. Then I got a whole bunch of errors of the form "Cannot convert const char* to char* in argmuent 3 of function foo". So, I went through and made a whole lot of changes to fix those. However, today, the program CRASHED because the literal "" was getting passed into a function that was expecting a char*, and was setting the 0th character to 0. It wasn't doing anything bad, just trying to edit a constant, and crashing. My question is, why wasn't that a compiler error? In case it matters, this was on a mac compiled with gcc-4.0.
