  • How to fill a section within c++ string?

    - by stacker
    Having a string of whitespaces: string *str = new string(); str->resize(width,' '); I'd like to fill length chars at a position. In C it would look like memset(&str[pos],'#', length ); How can i achieve this with c++ string, I tried string& assign( const string& str, size_type index, size_type len ); but this seems to truncat the original string. Is there an easy C++ way to do this? Thanks.

  • Getting value of LSB from Hex (C code)

    - by Rjff
    Hi - first post here :) I've got a code like this in C: unsigned char const data[ ] = {0x0a, 0x1d, 0xf0, 0x07}; I need to extract it such that the final value is: 0xa1df7 I have only been able to extract and get it working if the hex values that have at least 1 zero: unsigned char const data[ ] = {0x0a, 0xd0, 0xf0, 0x07}; using the code below: for(int i = 0; i < SIZE; ++i) { tmp = data[i]; if ( (data[i] <= 0x0F) && (((data[i] & 0x0F) == 0) || (data[i] & 0xF0) == 0)) // one of the hex is zero { tmp = ((tmp << 4) >> 4) << N[i]; std::cout << "foo: " << std::hex << tmp << ":" << std::endl; } else if ((data[i] >= 0x0F) && (((data[i] & 0x0F) == 0) || (data[i] & 0xF0) == 0) ) { tmp = (tmp >> 4) << N[i]; std::cout << "bar: " << std::hex << tmp << ":" << std::endl; } else { std::cout << "result: " << std::hex << result << ":" << std::endl; std::cout << "tmp << 8: " << std::hex << (tmp << 8)<< ":" << std::endl; result = result | (tmp << 8); std::cout << "result |= (tmp << 8): " << std::hex << result << ":" << std::endl; } result |= tmp; std::cout << "boo: " << std::hex << result << ":" << std::endl; } It seems the last else {...} block is troublesome for me. Any ideas? Thanks!

  • Adding the text area input to a list with jquery

    - by amylynn83
    I am making a shopping list app. When an item is added to the text input, it should be converted into a list item with a class of "tile" and added to the beginning of the list with a class of ".shopping_item_list". Here is my HTML: <section> <h1 class="outline">Shopping List Items</h1> <ul class="shopping_item_list"> <li class="tile">Flowers<span class="delete">Delete</span></li> </ul> </section> My jQuery: $("input[name='shopping_item']").change(function() { var item = $(this).val(); $("<li class='tile'>+ item +</li>").prependTo(".shopping_item_list"); $(".tile").removeClass("middle"); $(".shopping_item_list li:nth-child(3n+2)").addClass("middle"); }); This isn't working, and I can't figure out why. I'm new to jQuery. Also, I need to add the "delete" span to the list item and am not sure how. Thanks for any help you can offer! Edited to add: Thanks to the feedback here, I was able to make it work with: $("input[name='shopping_item']").change(function() { var item = $(this).val(); $("<li class='tile'>" + item + "<span class='delete'>Delete</span>" + " </li>").prependTo(".shopping_item_list"); $(".tile").removeClass("middle"); $(".shopping_item_list li:nth-child(3n+2)").addClass("middle"); }); However, in my jquery, I have functions for the classes "tile" and "delete" that are not working for newly added items. // hide delete button $(".delete").hide(); // delete square $(".tile").hover(function() { $(this).find(".delete").toggle(); }); $(".tile").on("click", ".delete", function() { $(this).closest("li.tile").remove(); $(".tile").removeClass("middle"); $(".shopping_item_list li:nth-child(3n+2)").addClass("middle"); }); // cross off list $(".tile").click(function() { $(this).toggleClass("deleteAction"); }); The new items, which have these classes applied aren't using these functions at all. Do I need to add the functions below the add item? Does the order in which they appear in my js file matter? Do I need to add some kind of function?

  • Python check if object is in list of objects

    - by John
    Hi, I have a list of objects in Python. I then have another list of objects. I want to go through the first list and see if any items appear in the second list. I thought I could simply do for item1 in list1: for item2 in list2: if item1 == item2: print "item %s in both lists" However this does not seem to work. Although if I do: if item1.title == item2.title: it works okay. I have more attributes than this though so don't really want to do 1 big if statement comparing all the attributes if I don't have to. Can anyone give me help or advise on what I can do to find the objects which appear in both lists. Thanks

  • parse this directory path without losing slash

    - by PPTim
    hi, I have a wxPython application. I am taking in a directory path from a textbox using GetValue(). I notice that while trying to parse in the directory path "C:\Documents and Settings\UserName\Desktop\InputFile.xls", python sees the string as 'C:\\Documents and Settings\UserName\\Desktop\\InputFile.xls' (missing a slash between "Settings" and "UserName). Why is it that only that slash is not correctly escaped? Once the string has been changed to 'C:\Documents and Settings\UserName\Desktop\InputFile.xls', is there a type conversion or function that can does this properly? Thanks.

  • iOS - How to iterate through list of files on website directory

    - by svjim
    On iOS, I am looking for the proper way to return the URLs for a list of files that are in a directory. /images 1.jpg 2.jpg 3.jpg ... I know the URL for the directory and know all the files in the directory will be of type jpeg. It is not clear to me how to properly format the NSURLRequest to return the list of files in the images directory. Once the list is returned, I will iterate through it to return the individual images.

  • Manipulating/changing adressbar link Help

    - by Karem
    I am out of my own "ideas" going through this. I have a album viewer. When you click next I want the adressbar to hang with it, e.g if you start on ?photoid=1, and click next (next picture appends and stuff), and then i want it to say ?photoid=2. Now I cant make it say ?photoid=2 without changing/manipulating, and this you cant do without HTML5. I have made a script in HTML5 that works fine, but then I need to take care of those who dont have HTML5(only chrome, ff4 etc supports html5) Made the script from this( https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history ) I thought of adding #photoid=2 so, ?photoid=1#photoid=2 and then check if theres anything in # then use that instead of the $_GET.. But apparently you cannot do that as # is client side handled and never sent to the server. So what should I then do? Any suggestions please to make a workaround this? I checked facebook, what they did to IE users, and I could hear that it "clicked" (the annoying click sound from IE) twice.. the first was to get to the next picture, the second click sound changed the adressbar?!(how?). And then I also thought hey, html5 is only supported in ff4, and I got ff3.6, and they manipulate the adress bar url when you browse through the album photos, exactly like how I wanted (and what I have written for but it only works in Chrome and ff4..?). How could they do that?

  • How to detect padding on an integer and treat it as a string?

    - by Sirber
    I have this function to prepare variable to be used in a SQL query: function sqlize($mInput) { if (!isset($mInput)) $mInput = "null"; elseif (strtolower($mInput) == "null") { } elseif (is_numeric($mInput)) { } elseif (is_string($mInput)) { $mInput = trim($mInput); $mInput = addslashes($mInput); $mInput = '"' . $mInput . '"'; } else $mInput = "null"; return $mInput; } I have a string "0004", which is going in a "varchar field", is cought by is_numeric, and is saved as "4" and not "0004". Is there a way to detect the padding and process it as a string? Thank you!

  • Are there any way to apply regexp in java ignoring letter case?

    - by Roman
    Simple example: we have string "Some sample string Of Text". And I want to filter out all stop words (i.e. "some" and "of") but I don't want to change letter case of other words which should be retained. If letter case was unimportant I would do this: str.toLowerCase().replaceAll ("a|the|of|some|any", ""); Is there an "ignore case" solution with regular expressions in java?

  • What should I know about Python to identify comments in different source files?

    - by Can't Tell
    I have a need to identify comments in different kinds of source files in a given directory. ( For example java,XML, JavaScript, bash). I have decided to do this using Python (as an attempt to learn Python). The questions I have are 1) What should I know about python to get this done? ( I have an idea that Regular Expressions will be useful but are there alternatives/other modules that will be useful? Libraries that I can use to get this done?) 2) Is Python a good choice for such a task? Will some other language make this easier to accomplish?

  • Getting a list of all phone contacts?

    - by pcm2a
    Simple enough question. I need to know the best way to get the same list of contacts that show up when a user presses the Contacts button. You would think something like this would work: //For Contacts Intent pickIntent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); //For Phones Intent pickIntent = new Intent(Intent.ACTION_PICK, Phones.CONTENT_URI); this.startActivityForResult(pickIntent, RESULT); The problem is that does not include secondary google accounts or Exchange contacts. By secondary accounts, in Android you can add additional gmail accounts to have the mail/contacts synced. The above intent will not list those additional contacts. I am also told that on the HTC Desire you can add contacts to the phone that do not get synced up to Google. These contacts also do not show up. So how do I get a real list of contacts so I can create my own list activity that works properly where the Google intent does not.

  • How to convert from string to a number, and vice-versa in C++?

    - by Igal
    DEAR All I'm new to the C++, so maybe someone can say what the proper way to write a function that gets a string char (represents number) and converts it to the integer number. For example : input : Sixty five, output: 65. Maybe it should use by cin.getline() ? Well, vice-versa is little bit simlper... Thanks for advance. Igal

  • C# type safe and developer friendly list/collection technique

    - by Agile Noob
    I am populating a "Dictionary" with the results of an sp call. The key is the field name and the value is whatever value the sp returns for the field. This is all well and good but I'd like developers to have a predefined list of keys to access this list, for safety and documentation reasons. What I'd like to do is have something like an enum as a key for the dictionary so developers can safely access the list, but still have the ability to access the dictionary with a string key value. I am hoping to have a list of string values that I can access with an enum key AND a string key. Please make sure any suggestions are simple to implement, this is not the kind of thing I'm willing to build a lot of overhead to implement.

  • Drawbacks of using an integer as a bitfield?

    - by Mark
    I have a bunch of boolean options for things like "accepted payment types" which can include things like cash, credit card, cheque, paypal, etc. Rather than having a half dozen booleans in my DB, I can just use an integer and assign each payment method an integer, like so PAYMENT_METHODS = ( (1<<0, 'Cash'), (1<<1, 'Credit Card'), (1<<2, 'Cheque'), (1<<3, 'Other'), ) and then query the specific bit in python to retrieve the flag. I know this means the database can't index by specific flags, but are there any other drawbacks?

  • How to manually (bitwise) perform (float)x? (homework)

    - by Silver
    Now, here is the function header of the function I'm supposed to implement: /* * float_from_int - Return bit-level equivalent of expression (float) x * Result is returned as unsigned int, but * it is to be interpreted as the bit-level representation of a * single-precision floating point values. * Legal ops: Any integer/unsigned operations incl. ||, &&. also if, while * Max ops: 30 * Rating: 4 */ unsigned float_from_int(int x) { ... } We aren't allowed to do float operations, or any kind of casting. Now I tried to implement the first algorithm given at this site: http://locklessinc.com/articles/i2f/ Here's my code: unsigned float_from_int(int x) { // grab sign bit int xIsNegative = 0; int absValOfX = x; if(x < 0){ xIsNegative = 1; absValOfX = -x; } // zero case if(x == 0){ return 0; } //int shiftsNeeded = 0; /*while(){ shiftsNeeded++; }*/ unsigned I2F_MAX_BITS = 15; unsigned I2F_MAX_INPUT = ((1 << I2F_MAX_BITS) - 1); unsigned I2F_SHIFT = (24 - I2F_MAX_BITS); unsigned result, i, exponent, fraction; if ((absValOfX & I2F_MAX_INPUT) == 0) result = 0; else { exponent = 126 + I2F_MAX_BITS; fraction = (absValOfX & I2F_MAX_INPUT) << I2F_SHIFT; i = 0; while(i < I2F_MAX_BITS) { if (fraction & 0x800000) break; else { fraction = fraction << 1; exponent = exponent - 1; } i++; } result = (xIsNegative << 31) | exponent << 23 | (fraction & 0x7fffff); } return result; } But it didn't work (see test error below): Test float_from_int(-2147483648[0x80000000]) failed... ...Gives 0[0x0]. Should be -822083584[0xcf000000] 4 4 0 float_times_four I don't know where to go from here. How should I go about parsing the float from this int?

  • BufferedImage & ColorModel in Java

    - by spol
    I am using a image processing library in java to manipulate images.The first step I do is I read an image and create a java.awt.Image.BufferedImage object. I do it in this way, BufferedImage sourceImage = ImageIO.read( new File( filePath ) ); The above code creates a BufferedImage ojbect with a DirectColorModel: rmask=ff0000 gmask=ff00 bmask=ff amask=0. This is what happens when I run the above code on my macbook. But when I run this same code on a linux machine (hosted server), this creates a BufferedImage object with ColorModel: #pixelBits = 24 numComponents = 3 color space = java.awt.color.ICC_ColorSpace@c39a20 transparency = 1 has alpha = false isAlphaPre = false. And I use the same jpg image in both the cases. I don't know why the color model on the same image is different when run on mac and linux. The colormodel for mac has 4 components and the colormodel for linux has 3 components.There is a problem arising because of this, the image processing library that I use always assumes that there are always 4 components in the colormodel of the image passed, and it throws array out of bounds exception when run on linux box. But on macbook, it runs fine. I am not sure if I am doing something wrong or there is a problem with the library. Please let me know your thoughts. Also ask me any questions if I am not making sense!

  • How do I build a python string from a raw (binary) ctype buffer?

    - by fcrazy
    I'm playing with Python and ctypes and I can't figure out how to resolve this problem. I call to a C function which fills a raw binary data. My code looks like this: class Client(): def __init__(self): self.__BUFSIZE = 1024*1024 self.__buf = ctypes.create_string_buffer(self.__BUFSIZE) self.client = ctypes.cdll.LoadLibrary(r"I:\bin\client.dll") def do_something(self): len_written = self.client.fill_raw_buffer(self.__buf, self.__BUFSIZE) my_string = repr(self.__buf.value) print my_string The problem is that I'm receiving binary data (with 0x00) and it's truncated when I tried to build my_string. How can I build my_string if self._buf contains null bytes 0x00? Any idea is welcome. Thanks

  • Find most significant bit (left-most) that is set in a bit array

    - by Claudiu
    I have a bit array implementation where the 0th index is the MSB of the first byte in an array, the 8th index is the MSB of the second byte, etc... What's a fast way to find the first bit that is set in this bit array? All the related solutions I have looked up find the first least significant bit, but I need the first most significant one. So, given 0x00A1, I want 9.

  • Is there a Windows utility that will let me do multiple programmatic find/replaces on text that I cu

    - by billmaya
    I've inherited some C# code that contains about a thousand lines of source that I need to modify, transforming it from this: newDataRow["to_dir"] = comboBox108.Text; To this: assetAttributes.Add("to_dir", comboBox108.Text); The lines occur in various places throughout the application in groups of 40 or 50. Modifying each line by hand in Visual Studio 2008 can be done but it's labor intensive and prone to errors. Is there a Windows utility out there that will let me cut and paste groups of code into it and then run some sort of reg-ex expression to transform the individual lines one-by-one? I'd also be willing to use some sort of VS 2008 add-in that performed the same set of reg-ex operations against a selection of code. Thanks in advance.

  • Remove items from one list in another

    - by coffeeaddict
    I'm trying to figure out how to traverse a generic list of items that I want to remove from another list of items. So lest say I have this as a hypothetical example List<car> list1 = GetTheList(); List<car> list2 = GetSomeOtherList(); I want to traverse list1 with a foreach and remove each item in List1 in List2. I'm not quite sure how to go about that as foreach is not index based.

  • C# Generic List constructor gives me a MethodAccessException

    - by evilfred
    Hi, I make a list in my code like so: List<IConnection> connections = new List<IConnection>(); where IConnection is my own interface. This is in a .NET 2.0 executable. If I run the code on my machine (with lots of .Net versions installed) it works fine. If I run it on my test machine (which only has .NET 3.5 SP1 installed) then I get a MethodAccessException in the System.Collections.Generic.List constructor. Any ideas what could be going wrong?
