  • split a string into a key => value array in php

    - by andy-score
    +2-1+18*+7-21+3*-4-5+6x29 The above string is an example of the kind of string I'm trying to split into either a key = value array or something similar. The numbers represent the id of a class and -,+ and x represent the state of the class (minimised, expanded or hidden), the * represents a column break. I can split this into the columns easily using explode which gives and array with 3 $key = $value associations. eg. $column_layout = array( [0] => '+2-1+18' , [1] => '+7-21+3' , [2] => '-4-5+6x29' ) I then need to split this into the various classes from there, keeping the status and id together. eg. $column1 = array( '+' => 2 , '-' => 1 , '+' => 18 ) ... or $column1 = array( array( '+' , 2 ) , array( '-' , 1 ) , array( '+' , 18 ) ) ... I can't quite get my head round this and what the best way to do it is, so any help would be much appreciated.

  • Javascript: How to escape Unicode Chars

    - by user293006
    JSON String: { "id":31896, "name":"Zickey attitude - McKinley, La Rosi\u00e8re, 21 ao\u00fbt 2006", ... } this causes an unterminated string in javascript. my focus on solution is: data.replace(/(\S)\1(\1)+/g, ''); or data.replace(/\u([0-9A-Z])/, ''); any ideas/solution? example: http://api.jamendo.com/get2/id+name+url+stream+album_name+album_url+album_id+artist_id+artist_name/track/jsonpretty/track_album+album_artist/?n=13&order=ratingmonth_desc&tag_idstr=jazz last node is the problem, fyi. (/\u([0-9A-Z])/, '\1');

  • C#: Loop through substring patterns in a string

    - by ilann
    my pattern is the following: {(code)} where code is a number (up to 6 digits), or 2 letter followed by a number. For example: {(45367)} {(265367)} {(EF127012)} I want to find all occurrences in a long string, I can't just use pure regex , because I need to preform some action when i find a match (like logging the position and the type of the match).

  • string update in sqlserver

    - by Thiyaneshwaran S
    Currently i have varchar field. The delimiter is "$P$P$". The delimiter will appear atleast once and atmost twice in the varchar data. Eg. Sample Heading$P$P$Sample description$P$P$Sample conclusion Sample Heading$P$P$Sample Description If the delimiter appears twice, i need to insert a text before the second occurance of the delimiter. Eg: Sample Heading$P$P$Sample DescriptionINSERT TEXT HERE$P$P$Sample Conclusion If the delimiter occurs only once, then i need to insert a text at the end of the field. Eg: Sample Heading$P$P$Sample DescriptionAPPEND TEXT HERE How this can be done in sql query?

  • How do I unpack bits from a structure's stream_data in c code?

    - by Chelp
    Ex. typedef struct { bool streamValid; dword dateTime; dword timeStamp; stream_data[800]; } RadioDataA; Ex. Where stream_data[800] contains: **Variable** **Length (in bits)** packetID 8 packetL 8 versionMajor 4 versionMinor 4 radioID 8 etc.. I need to write: void unpackData(radioDataA *streamData, MA_DataA *maData) { //unpack streamData (from above) & put some of the data into maData //How do I read in bits of data? I know it's by groups of 8 but I don't understand how. //MAData is also a struct. }

  • Manipulate method functionality call

    - by danrichardson
    Hello, is it possibly in c# to have some sort of base class functionality which is manipulated slightly based on the class. For instance say i have the following code (which will quite obviously not compile it's meant to only be for demonstrative purposes) class BaseFunctionality { public virtual bool adminCall public static string MethodName(int id, string parameter) { if (adminCall) return dbcall.Execute(); else return dbcall.ExecuteMe(); } } class Admin : BaseFunctionality { override bool adminCall = true; } class Front : BaseFunctionality { override bool adminCall = false; } Now what i would like to be able to do is; string AdminCall = Admin.MethodName(1, "foo"); string FrontCall = Front.MethodName(2, "bar"); Is their any way to do something like this? I'm trying to do everything with static methods so i do not have to instantiate classes all the time, and have nice clean code which is only being manipulated in one place. The idea behind this is so that there is minimal code repeating and makes things easier to expand on, so for instance another class could implement the BaseFunctionality later on. Thanks Dan

  • Remove specified text from beginning of lines only if present (C#)

    - by Zach
    I have a textbox in which the user can edit text, in a scripting language. I've figured out how to let the user comment out lines in one click, but can't seem to figure out how to uncomment properly. For example, if the box has: Normal Text is here More normal text -- Commented text -- More commented text Normal Text again --Commented Text Again So, when the user selects any amount of text and decides to uncomment, the "--" is removed from the beginning of the lines that have it. The lines without the "--" should be unaffected. In short, I want an uncomment function that performs similar to the one in Visual Studio. Is there any way to accomplish this? Thanks

  • How could I insert a string into the response stream anywhere I want?

    - by DM
    There may be an easy way to do this but I can't see it... I created a simple Http Module that starts a timer on the PreRequestHandler and stops the timer on the PostRequestHandler to calculate the time it took the page to load. I then create some simple html and write my results to Response.Write. Since I'm doing this in the PostRequestHandler it's adding my results after the </html> tag. That's fine for testing but I need in a scenario where the page needs to validate. I can't seem to figure out how I could manipulate the Response object to insert my results before the </body> tag. Response.Write and Response.Output.Write don't have that flexibility and I couldn't see a way to work with the Response as a string. Am I missing something easy?

  • Why string.Replace("X","Y") works only when assigned to new string?

    - by Petr
    Hi, I guess it has to do something with string being a reference type but I dont get why simply string.Replace("X","Y") does not work? Why I need to do `string A=stringB.Replace("X","Y") I thought it is just a method to be done on specified instance? Thanks for explanation EDIT: Thank you so far. I extend my question Why "b+="FFF"works but the b.replace is not?

  • how to retrieve substring from string having variable length of character in php?

    - by user187580
    Hello I have some data in the format of C222 = 50 C1234P687 = 'some text' C123YYY = 'text' C444 = 89 C345 = 3 C122P687 = 'some text' C122YYY = 'text' .... .... so basically 3 different forms "C" number = value, example - C444 = 89 "C" number "P" number = value, example - C123P687 = 'some text' "C" number "YYY" = value Only number is of variable length on the left side of (=) sign. Values vary. I want to store the data in db as INSERT INTO datatable c_id = "number after C" p_id = "number after P" // if it exists for a line of data value = 'value' yyy = 'value' Any ideas how to retrieve these numbers? Thanks

  • How does one find a '.' in a string object in Object-C

    - by NaZer
    I am working on getting a simple calculator working as part of my adventure to learning Object-C and iOS development. In Object-C using NSString, how does one look for a period in a string? Based on the comments this is what I got so far. NSString * tmp = [display text]; NSLog(@"%@", tmp); // Shows the number on the display correctly int x = [tmp rangeOfString:@"."].location; NSLog(@"%i", x); // Shows some random signed number if (x < 0) { [display setText:[[display text] stringByAppendingFormat:@"."]]; } It is still not working :(

  • Getting the fractional part of a float without using modf()

    - by knight666
    Hi, I'm developing for a platform without a math library, so I need to build my own tools. My current way of getting the fraction is to convert the float to fixed point (multiply with (float)0xFFFF, cast to int), get only the lower part (mask with 0xFFFF) and convert it back to a float again. However, the imprecision is killing me. I'm using my Frac() and InvFrac() functions to draw an anti-aliased line. Using modf I get a perfectly smooth line. With my own method pixels start jumping around due to precision loss. This is my code: const float fp_amount = (float)(0xFFFF); const float fp_amount_inv = 1.f / fp_amount; inline float Frac(float a_X) { return ((int)(a_X * fp_amount) & 0xFFFF) * fp_amount_inv; } inline float Frac(float a_X) { return (0xFFFF - (int)(a_X * fp_amount) & 0xFFFF) * fp_amount_inv; } Thanks in advance!

  • What's the easiest way to assign a string returned from the server to a javascript string?

    - by powerboy
    The following does not work: var js_str= '<?php echo $str_from_server; ?>'; The problem is that, $str_from_server can contain any characters. If it contains single quotes or line breaks or others, the above code will break. And I do not have access to the server-side code. What's the easiest way to "escape" the contents of $str_from_server into a javascript string, and then it can be restored later?

But I've got nothing, I just get, format decimal such ass 1,000,000.00. I hope you can suggest me a reference or give me something to solve this problem. Thanks Edit, we can use NumberFormat, or String.format("%4d", somevalue); but it just for adding 0 character before integer. How If I wanna use character such as x, # or maybe whitespace. So the character become: xxxx1 xxx10 or ####1 ###10 or 1#### 10###

  • Strings in ASP?

    - by TSL
    Hi All, I have some APSX code that I am trying to modify for a programmer that is out on medicaly leave. I am not an ASP guy, but rather C++ So what I want to do is delare a string, check the first 4 characters and if it is 'http' do something, if not, something else. Here is what I have: string strYT= Left(objFile, 4); if (strYT=="http") { pnlYT.Visible = true; pnlIntro.Visible = false; pnlVideo.Visible = false; } else { pnlYT.Visible = false; pnlIntro.Visible = false; pnlVideo.Visible = true; PrintText(objFile); } But I get errors like: Compiler Error Message: CS0103: The name 'Left' does not exist in the class or namespace 'ASP.zen_aspx' My googling turns up many examples of doing it just like this.....

  • MVC and Checkboxes...leaves a bit to be desired

    - by Josh
    Here is my problem. I have a list of models that are displayed to the user. On the left is a checkbox for each model to indicate that the user wants to choose this model (in this case, we're building products a user can add to their shopping cart). The model has no concept of being chosen...it strictly has information about the product in question. I've talked with a few other developers after having gone through and the best I could come up with is getting the formcollection and string parsing the key values to determine whether the checkbox is checked or not. This doesn't seem ideal. I was thinking there would be something more strongly bound, but I can't figure out a way to do it. I tried creating another model that had a boolean property to represent being checked and a property of the model and passing a list of that model type to the view and creating a ActionResult on the controller that accepts a list of the new model / checked property, but it comes back null. Am I just thinking too much like web forms and should just continue on with parsing checkbox values?
