  • Parsing string logic issue c#

    - by N0xus
    This is a follow on from this question My program is taking in a string that is comprised of two parts: a distance value and an id number respectively. I've split these up and stored them in local variables inside my program. All of the id numbers are stored in a dictionary and are used check the incoming distance value. Though I should note that each string that gets sent into my program from the device is passed along on a single string. The next time my program receives that a signal from a device, it overrides the previous data that was there before. Should the id key coming into my program match one inside my dictionary, then a variable held next to my dictionaries key, should be updated. However, when I run my program, I don't get 6 different values, I only get the same value and they all update at the same time. This is all the code I have written trying to do this: Dictionary<string, string> myDictonary = new Dictionary<string, string>(); string Value1 = ""; string Value2 = ""; string Value3 = ""; string Value4 = ""; string Value5 = ""; string Value6 = ""; void Start() { myDictonary.Add("11111111", Value1); myDictonary.Add("22222222", Value2); myDictonary.Add("33333333", Value3); myDictonary.Add("44444444", Value4); myDictonary.Add("55555555", Value5); myDictonary.Add("66666666", Value6); } private void AppendString(string message) { testMessage = message; string[] messages = message.Split(','); foreach(string w in messages) { if(!message.StartsWith(" ")) outputContent.text += w + "\n"; } messageCount = "RSSI number " + messages[0]; uuidString = "UUID number " + messages[1]; if(myDictonary.ContainsKey(messages[1])) { Value1 = messageCount; Value2 = messageCount; Value3 = messageCount; Value4 = messageCount; Value5 = messageCount; Value6 = messageCount; } } How can I get it so that when programs recives the first key, for example 1111111, it only updates Value1? The information that comes through can be dynamic, so I'd like to avoid harding as much information as I possibly can.

  • Date formatting using data annotations for a dataform in Silverlight

    - by Aim Kai
    This is probably got a simple answer to it, but I am having problems just formatting the date for a dataform field.. <df:DataForm x:Name="Form1" ItemsSource="{Binding Mode=OneWay}" AutoGenerateFields="True" AutoEdit="True" AutoCommit="False" CommitButtonContent="Save" CancelButtonContent="Cancel" CommandButtonsVisibility="Commit" LabelPosition="Top" ScrollViewer.VerticalScrollBarVisibility="Disabled" EditEnded="NoteForm_EditEnded"> <df:DataForm.EditTemplate> <DataTemplate> <StackPanel> <df:DataField> <TextBox Text="{Binding Title, Mode=TwoWay}"/> </df:DataField> <df:DataField> <TextBox Text="{Binding Description, Mode=TwoWay}" AcceptsReturn="True" HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" Height="" TextWrapping="Wrap" SizeChanged="TextBox_SizeChanged"/> </df:DataField> <df:DataField> <TextBlock Text="{Binding Username}"/> </df:DataField> <df:DataField> <TextBlock Text="{Binding DateCreated}"/> </df:DataField> </StackPanel> </DataTemplate> </df:DataForm.EditTemplate> </df:DataForm> I have bound this to a note class which has the annotation for field DateCreated: /// <summary> /// Gets or sets the date created of the noteannotation /// </summary> [Display(Name="Date Created")] [Editable(false)] [DisplayFormat(DataFormatString = "{0:u}", ApplyFormatInEditMode = true)] public DateTime DateCreated { get; set; } Whatever I set the dataformatstring it comes back as: eg 4/6/2010 10:02:15 AM I want this formatted as yyyy-MM-dd HH:mm:ss I have tried the custom format above {0:yyyy-MM-dd hh:mm:ss} but it remains the same output. The same happens for {0:u} or {0:s}. Any help would be gratefully received. :)

  • compact Number formatting behavior in Java (automatically switch between decimal and scientific notation)

    - by kostmo
    I am looking for a way to format a floating point number dynamically in either standard decimal format or scientific notation, depending on the value of the number. For moderate magnitudes, the number should be formatted as a decimal with trailing zeros suppressed. If the floating point number is equal to an integral value, the decimal point should also be suppressed. For extreme magnitudes (very small or very large), the number should be expressed in scientific notation. Alternately stated, if the number of characters in the expression as standard decimal notation exceeds a certain threshold, switch to scientific notation. I should have control over the maximum number of digits of precision, but I don't want trailing zeros appended to express the minimum precision; all trailing zeros should be suppressed. Basically, it should optimize for compactness and readability. 2.80000 - 2.8 765.000000 - 765 0.0073943162953 - 0.00739432 (limit digits of precision—to 6 in this case) 0.0000073943162953 - 7.39432E-6 (switch to scientific notation if the magnitude is small enough—less than 1E-5 in this case) 7394316295300000 - 7.39432E+6 (switch to scientific notation if the magnitude is large enough—for example, when greater than 1E+10) 0.0000073900000000 - 7.39E-6 (strip trailing zeros from significand in scientific notation) 0.000007299998344 - 7.3E-6 (rounding from the 6-digit precision limit causes this number to have trailing zeros which are stripped) Here's what I've found so far: The .toString() method of the Number class does most of what I want, except it doesn't upconvert to integer representation when possible, and it will not express large integral magnitudes in scientific notation. Also, I'm not sure how to adjust the precision. The "%G" format string to the String.format(...) function allows me to express numbers in scientific notation with adjustable precision, but does not strip trailing zeros. I'm wondering if there's already some library function out there that meets these criteria. I guess the only stumbling block for writing this myself is having to strip the trailing zeros from the significand in scientific notation produced by %G.

  • Preserve whitespace and formatting for text returned from $.get jquery call

    - by desigeek
    I have a jquery $.get() call in my app that requests an entire web page. In the callback function, I access a div in the returned page, get its data and show it on my page. The problem is that the text I get from the div does not preserve the source formatting. If the div in the requested page had say an ordered list, then when i get that text and display on my page, it shows up as a paragraph with items inline instead of being shown as a list. I do not know whether the problem is how $.get() is getting the data or in my displaying of the data. //get the page $.get($(this).attr('href'), function(data){ callbackFunc(data,myLink); }, "html"); function callbackFunc(responseText, customData){ //response has bg color of #DFDFDF var td = $("td[bgcolor='#DFDFDF']", responseText); //text to show is in div of that td var forumText = $('div', td).text(); //append new row with request data below the current row in my table var currentRow = $(customData).parent('td').parent('tr'); var toAppend = "<tr><td class='myTd' colspan='3'>" + forumText + "</td></tr>"; $(currentRow).after(toAppend); } The response data shows up like ABC in the new row I add to my div while the source page div had A B C I should add that this script is part of an extension for Google Chrome so that is my only browser that I have tested on

  • CSS Table Formatting to a HTML Table

    - by Rurigok
    I am attempting to provide CSS formating to two HTML tables, but I cannot. I am setting up a webpage in HTML & CSS (with the CSS in an external sheet) and the layout of the website depends on the tables. There are 2 tables, one for the head and another for the body. They are set up whereas content is situated in one middle column of 60% width, with one column on each side of the center with 20% width each, along with other table formatting. My question is - how can I format the tables in CSS? I successfully formatted them in HTML, but this will not do. This is the CSS code for the tables - each table has the id layouttable: #layouttable{border:0px;width:100%;} #layouttable td{width:20%;vertical-align:top;} #layouttable td{width:60%;vertical-align:top;background-color:#E8E8E8;} #layouttable td{width:20%;vertical-align:top;} The tables in the html document both each have, in respective order, these elements (with content inside not shown): <table id="layouttable"><tr><td></td><td></td><td></td></tr></table> Does anyone have any idea why this CSS is not working, or can write some code to fix it? If further explanation is needed, please, ask.

  • Fast string suffix checking in C# (.NET 4.0)?

    - by ilitirit
    What is the fastest method of checking string suffixes in C#? I need to check each string in a large list (anywhere from 5000 to 100000 items) for a particular term. The term is guaranteed never to be embedded within the string. In other words, if the string contains the term, it will be at the end of the string. The string is also guaranteed to be longer than the suffix. Cultural information is not important. These are how different methods performed against 100000 strings (half of them have the suffix): 1. Substring Comparison - 13.60ms 2. String.Contains - 22.33ms 3. CompareInfo.IsSuffix - 24.60ms 4. String.EndsWith - 29.08ms 5. String.LastIndexOf - 30.68ms These are average times. [Edit] Forgot to mention that the strings also get put into separate lists, but this is not important. It does add to the running time though. On my system substring comparison (extracting the end of the string using the String.Substring method and comparing it to the suffix term) is consistently the fastest when tested against 100000 strings. The problem with using substring comparison though is that Garbage Collection can slow it down considerably (more than the other methods) because String.Substring creates new strings. The effect is not as bad in .NET 4.0 as it was in 3.5 and below, but it is still noticeable. In my tests, String.Substring performed consistently slower on sets of 12000-13000 strings. This will obviously differ between systems and implementations. [EDIT] Benchmark code: http://pastebin.com/smEtYNYN

  • Advice on String Similarity Metrics (Java). Distance, sounds like or combo?

    - by andreas
    Hello, A part of a process requires to apply String Similarity Algorithms. The results of this process will be stored and produce lets say SS_Dataset. Based on this Dataset, further decisions will have to be made. My questions are: Should i apply one or more string similarity algorithms to produce SS_Dataset ? Any comparisons between algorithms that calculate the 'distance' and the 'Sounds Like' similarity ? Does one family of algorithms produces more accurate results over the other? Does a combination give more accurate results on similarity? Can you recommend implementations that you have worked with? My implementation will include packages from the following libraries http://www.dcs.shef.ac.uk/~sam/simmetrics.html http://jtmt.sourceforge.net/ Regards,

  • Delphi Unicode String Type Stored Directly at its Address

    - by Andreas Rejbrand
    I want a string type that is Unicode and that stores the string directly at the adress of the variable, as is the case of the (Ansi-only) ShortString type. I mean, if I declare a S: ShortString and let S := 'My String', then, at @S, I will find the length of the string (as one byte, so the string cannot contain more than 255 characters) followed by the ANSI-encoded string itself. What I would like is a Unicode variant of this. That is, I want a string type such that, at @S, I will find a unsigned 32-bit integer containing the length of the string in bytes (or in characters, which is half the number of bytes) followed by the Unicode representation of the string. I have tried WideString, UnicodeString, and RawByteString, but they all appear only to store an adress at @S, and the actual string somewhere else (I guess this has do do with reference counting and such). I suspect that there is no built-in type to use, and that I have to come up with my own way of storing text the way I want (which actually is fun). Am I right?

  • Insert string between two markers

    - by user275074
    I have a requirement to insert a string between two markers. Initially I get a sting (from a file stored on the server) between #DATA# and #END# using: function getStringBetweenStrings($string,$start,$end){ $startsAt=strpos($string,$start)+strlen($start); $endsAt=strpos($string,$end, $startsAt); return substr($string,$startsAt,$endsAt-$startsAt); } I do some processing and based on the details of the string, query for some records. If there are records I need to be able to append them at the end of the string and then re-insert the string between #DATA# and #END# within the file on the server. How can I best achieve this? Is it possible to insert a record at a time in the file before #END# or is it best to manipulate the string on the server and just re-insert over the existing string in the file on the server?

  • how to retrieve part of a string in java?

    - by mithun1538
    Hello everyone, I am designing a chat applet. In this, a user will append his name to the beginning of the message that he sends to the other user. In the window of other user, I want to retrieve the appended user name from that string. How do I do that? The message sent by the user is as follows : final_msg = user_name + ": " + user_message Hence I want to know how to retrieve the user_name string only. Is there a function that can retrieve a substring upto the first ":"? I dont want to use final_msg.split(":"), because there is a possiblity that the user_message contains ":", which will then give me an array of strings.

  • Regex for url formatting (www.domain.tld to anchors)

    - by Kristaps
    Hi. I'm currently developing a little browser-based Twitter widget. Currently, I'm stuck with getting the URLs to work. I'm kinda newbie, when it comes to regex (I know, how to get parts of a string, but this one – tough one). So, I need a regex that would search/replace www.domain.tld -> <a href="http://www.domain.tld">http://www.domain.tld</a> With/without http://, preferably. Any advice is welcome. Thanks.

  • Can't return a String value and append it...why?

    - by squeezemylime
    I am writing an app and am having problems returning a simple string value, and I'm not sure why. The function I am using (within a file called APIManager.m) is: - (NSString*) returnVenueUrl { NSString *venueUrl = [devEnvironment stringByAppendingString:@"venue/id/"]; return venueUrl; } I can return this properly by doing this in another .m file: APIManager *apiManager = [APIManager apiManager]; NSLog(@"view venue URL is here: %@", [apiManager returnVenueUrl]); But when I go to append a variable cast as a String onto it, I get nothing.. venueURL = [apiManager returnVenueUrl]; venueURL = [venueURL stringByAppendingString:venueId]; NSLog(@"the Full Venue URL is: %", venueURL); If anyone has any advice on how to fix this, it would be much appreciated!

  • Comparing strings that contain formatting in C#

    - by Finglas
    I'm working on a function that given some settings - such as line spacing, the output (in string form) is modified. In order to test such scenarios, I'm using string literals, as shown below for the expected result. The method, using a string builder, (AppendLine) generates the said output. One issue I have run into is that of comparing such strings. In the example below, both are equal in terms of what they represent. The result is the area which I care about, however when comparing two strings, one literal, one not, equality naturally fails. This is because one of the strings emits line spacing, while the other only demonstrates the formatting it contains. What would be the best way of solving this equality problem? I do care about formatting such as new lines from the result of the method, this is crucially important. Code: string expected = @"Test\n\n\nEnd Test."; string result = "Test\n\n\nEnd Test"; Console.WriteLine(expected); Console.WriteLine(result); Output: Test\n\n\nEnd Test. Test End Test

  • C#: How to detect . in string and insert a space after it/How to insert space after n chars?

    - by Sam Gentile
    Suppose I have a long string like "4600airportburlingame150anzablvd.burlingamecalifornia94010". My code is breaking on this string. This is UNUSUAL. 99% of entries will NOT have a period. The CSS in the browser wraps IF there are spaces in the string and there isn't any here. How do I detect the period (".") and insert a space directly after it? Remember 99% of strings will NOT have a period in them. The code has to detect if it has a period and if so, do the insertion, otherwise not. If I determine a maximum string length, how do I insert a space at some length? Thanks

  • Convert array to CSV/TSV-formated string in Python.

    - by dreeves
    Python provides csv.DictWriter for outputting CSV to a file. What is the simplest way to output CSV to a string or to stdout? For example, given a 2D array like this: [["a b c", "1,2,3"], ["i \"comma-heart\" you", "i \",heart\" u, too"]] return the following string: "a b c, \"1, 2, 3\"\n\"i \"\"comma-heart\"\" you\", \"i \"\",heart\"\" u, too\"" which when printed would look like this: a b c, "1,2,3" "i ""heart"" you", "i "",heart"" u, too" (I'm taking csv.DictWriter's word for it that that is in fact the canonical way to output that array as CSV. Excel does parse it correctly that way, though Mathematica does not. From a quick look at the wikipedia page on CSV it seems Mathematica is wrong.) One way would be to write to a temp file with csv.DictWriter and read it back with csv.DictReader. What's a better way? TSV instead of CSV It also occurs to me that I'm not wedded to CSV. TSV would make a lot of the headaches with delimiters and quotes go away: just replace tabs with spaces in the entries of the 2D array and then just intersperse tabs and newlines and you're done. Let's include solutions for both TSV and CSV in the answers to make this as useful as possible for future searchers.

  • Number of simple mutations to change one string to another?

    - by mstksg
    Hi; I'm sure you've all heard of the "Word game", where you try to change one word to another by changing one letter at a time, and only going through valid English words. I'm trying to implement an A* Algorithm to solve it (just to flesh out my understanding of A*) and one of the things that is needed is a minimum-distance heuristic. That is, the minimum number of one of these three mutations that can turn an arbitrary string a into another string b: 1) Change one letter for another 2) Add one letter at a spot before or after any letter 3) Remove any letter Examples aabca => abaca: aabca abca abaca = 2 abcdebf => bgabf: abcdebf bcdebf bcdbf bgdbf bgabf = 4 I've tried many algorithms out; I can't seem to find one that gives the actual answer every time. In fact, sometimes I'm not sure if even my human reasoning is finding the best answer. Does anyone know any algorithm for such purpose? Or maybe can help me find one? Thanks.
