  • iPhone question: How can I add a button to a tableview cell?

    - by Jake
    Hi guys, Little background, the table view is filled by a fetchedResultsController which fills the table view with Strings. Now I'm trying to add a button next to each String in each tableview cell. So far, I've been trying to create a button in my configureCell:atIndexPath method and then add that button as a subview to the table cell's content view, but for some reason the buttons do not show up. Below is the relevant code. If anyone wants more code posted, just ask and I'll put up whatever you want. Any help is greatly appreciated. - (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath { // get object that has the string that will be put in the table cell Task *task = [fetchedResultsController objectAtIndexPath:indexPath]; //make button UIButton *button = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain]; [button setTitle:@"Check" forState:UIControlStateNormal]; [button setTitle:@"Checked" forState:UIControlStateHighlighted]; //set the table cell text equal to the object's property cell.textLabel.text = [task taskName]; //addbutton as a subview [cell.contentView addSubview:button]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell. [self configureCell:cell atIndexPath:indexPath]; return cell; }

  • Search and highlight html - ignoring and maintaining tags

    - by Sleepwalker
    I am looking for a good way to highlight key words in a block of html with stripping the html tags. I can regex to search for key words within html tags, but I haven't found a great way to search across tags. For example, if the key word phrase is "not bound" I want to be able to make this <p>I am not<strong>bound to please thee</strong> with my answers.</p> become wrapped in highlight tags, without breaking the "strong" tag (and making the html invalid) and become: <p>I am <span class="highlight">not</span><strong><span class="highlight">bound</span> to please thee</strong> with my answers.</p> The main issue is maintaining the html as it is AND wrapping blocks of text with highlight tags. I need to maintain the original html. Otherwise I would strip the tags. The best solution to this that I can think of right now would entail making a copy of the html and placing counter tokens where each space occurs, then stripping all tags and search for matching phrases, then looking back to the original and the tokenized strings and figuring out where to start building the highlight tags, then start walking forward, starting and ending highlight spans as needed from the beginning of the match until the end. This seems like overkill. I would like to something more elegant if possible. The solution would be written in C# or perhaps javascript, depending.

  • Django/jQuery - read file and pass to browser as file download prompt

    - by danspants
    I've previously asked a question regarding passing files to the browser so a user receives a download prompt. However these files were really just strings creatd at the end of a function and it was simple to pass them to an iframe's src attribute for the desired effect. Now I have a more ambitious requirement, I need to pass pre existing files of any format to the browser. I have attempted this using the following code: def return_file(request): try: bob=open(urllib.unquote(request.POST["file"]),"rb") response=HttpResponse(content=bob,mimetype="application/x-unknown") response["Content-Disposition"] = "attachment; filename=nothing.xls" return HttpResponse(response) except: return HttpResponse(sys.exc_info()) With my original setup the following jQuery was sufficient to give the desired download prompt: jQuery('#download').attr("src","/return_file/"); However this won't work anymore as I need to pass POST values to the function. my attempt to rectify that is below, but instead of a download prompt I get the file displayed as text. jQuery.get("/return_file/",{"file":"c:/filename.xls"},function(data) { jQuery(thisButton).children("iframe").attr("src",data); }); Any ideas as to where I'm going wrong? Thanks!

  • Create bookmark into 1st column of MSWord table

    - by MikeD
    Hello All, does anyone have a VBA code to create a bookmark into the first column of an MSWord table? Let's say I have a table looking like this .-----.----------------. . ref . Title . .-----.----------------. . 1 . Title 1 . .-----.----------------. . 2 . Title 2 . .-----.----------------. . foo . Title 3 . .-----.----------------. . bar . Title 4 . .-----.----------------. and I want a VBA code fragment that creates a bookmark named "T1_1" on the string "1" in row 2 / column 1, and bookmarks named "T1_2", "T1_foo" and "T1_bar" on the strings in the other cells of column 1. I don't mind to hardcode the prefix "T1" (and substitute for other tables each time). I don't mind to select tables before running the macro, I don't mind giving those cells a special format, and I don't mind to get a superfluous bookmark "T1_ref" from the first row - so the code doesn't need to distinguish between table title and table row. Thanks a lot in advance

  • Looking for a fast, compact, streamable, multi-language, strongly typed serialization format

    - by sanity
    I'm currently using JSON (compressed via gzip) in my Java project, in which I need to store a large number of objects (hundreds of millions) on disk. I have one JSON object per line, and disallow linebreaks within the JSON object. This way I can stream the data off disk line-by-line without having to read the entire file at once. It turns out that parsing the JSON code (using http://www.json.org/java/) is a bigger overhead than either pulling the raw data off disk, or decompressing it (which I do on the fly). Ideally what I'd like is a strongly-typed serialization format, where I can specify "this object field is a list of strings" (for example), and because the system knows what to expect, it can deserialize it quickly. I can also specify the format just by giving someone else its "type". It would also need to be cross-platform. I use Java, but work with people using PHP, Python, and other languages. So, to recap, it should be: Strongly typed Streamable (ie. read a file bit by bit without having to load it all into RAM at once) Cross platform (including Java and PHP) Fast Free (as in speech) Any pointers?

  • Unable to browse some pdfs and docs.

    - by JamesEggers
    I have a web site that uses Microsoft Indexing Service to index and query a directory that holds various documents of type pdf, rtf, mht, and doc. The indexing and querying works well (for the most part); however, some files will load while others will not. This is a Windows Server 2003 box running the site using IIS 6. The indexed directory is a sub directory off of the site's root directory (i.e. http://my.domain.com/files/). The file paths are accurate in the URL; however, I can only access some of the files of each file type. The files that I cannot access give a 404 File Not Found. I am able to open all files via windows explorer;however, attempting to open them via a browser over http is hit and miss. Has anyone experienced this issue and know how to resolve it? Anyone have any idea why I could access some files but not others? Does anyone have any recommendations on what to look into to try this (i.e. does owner matter or something like that?)?

  • How do I send text to a UITextView?

    - by Lee
    I'm new to iphone development. I'm a VB programmer who is trying to convert a VB application to an ipad app. I need some help with sending text to a UITextView. I want to first have a UIPickerView and then once the user hits a UIButton, a UITextView appears and the text is then generated by my source code code, line by line. The code would constantly be concatenating strings to the text. It would sort of go like this-- 1) User makes selections with UIPickerView. 2) User then hits UIButton. 3) UIPickerView is replaced on the screen with a UITextView. 4) The code does stuff. 5) The code adds the 1st line of text into the UITextView. 6) The code does more stuff. 7) The code then adds the 2nd line of text into the UITextView, retaining the 1st line that was already there. Steps 6 and 7 are repeated until the code is done. Does anyone know of any examples of this that I could look at? I am mostly interested in finding something like a youtube video, a webpage that explains the code or even a good book that covers this particular topic. I am finding that the sample codes that Apple has on this site goes over my head. In fact, I could probably benefit from a good book. But, I am looking for one that I would already know covers this particular topic, since it is so essential to the app that I am trying to build.

  • Using Scala and StringTemplate, how do I loop through a Map

    - by Marcus Kazmierczak
    I have my environment setup nicely using Scala, StringTempalte within the Google AppEngine. I am having trouble looping through a Map and getting it to display in the template. When I assign a simple List of just Strings to the template it works using: In Scala Servlet: var photos = List[String]() //... get photo url and title ... photos = photo_url :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo$_s.jpg"></div> }$ The above works. However, any attempt of creating a Map using url and title and assigning to the template gives me an error. Here is my attempt, which does not work: In Scala Servlet: var photos = List[Map[String,String]]() //... get photo url and title ... photos = Map("url" -> url, "title" -> title) :: photos template.setAttribute("photos", photos: _*) In Template: $photos: { photo| <div><img src="$photo.url$_s.jpg" title="$photo.title$"></div> }$ This gives me the following error Class scala.collection.immutable.Map$Map2 has no such attribute: title in template context Thoughts / Ideas ?

  • Regular Expression Newbie

    - by Registered User
    I need to parse strings inputs where the columns are separated by columns and any field that contains a comma in the data is wrapped in quotes (commas separated, quoted text identifiers). For this project I need to remove the quotes and any commas that occur between pairs of quotes. Basically, I need to remove commas and quotes that are contained in fields while preserving the commas that are used to separate the fields. Here's a little code I put together that handles the simple scenario: // Sample input 1: This works and covers 99% of the records that I need to parse. string str1 = "[email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,\"This Address Works, Suite 200\",Some City,TN,09876-5432,9795551212x123,XYZ"; str1 = Regex.Replace(str1, "\"([^\"^,]*),([^\"^,]*)\"", "$1$2"); Console.WriteLine(str1); // Outputs: [email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,This Address Works Suite 200,Some City,TN,09876-5432,9795551212x123,XYZ Although this code works for most of my records, it doesn't work when a field contains more than one commas. What I would like to do is modify the code so that it remove each instance of a comma contained within the column no matter how many commas there are in the field. I don't want to hard code only handling 2 commas, or 3 commas, or 25 commas. The code should just remove all the commas in the field. Below is an example of what my code doesn't handle properly. // Sample input 2: This doesn't work since there is more than 1 comma between the quotes. string str2 = "[email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,\"i,l,k,e, c,o,m,m,a,s, i,n ,m,y, f,i,e,l,d\",Some City,TN,09876-5432,9795551212x123,XYZ"; str2 = Regex.Replace(str2, "\"([^\"^,]*),([^\"^,]*)\"", "$1$2"); Console.WriteLine(str2); // Desired output: [email protected],2010/03/27 12:2:02,,some_first_name,some_last_name,,i like commas in my field,Some City,TN,09876-5432,9795551212x123,XYZ Any help would be appreciated for this Regular Expression newbie.

  • wpf & validation application block > message localization > messageTemplateResource Name&Type

    - by Shaboboo
    I'm trying to write validation rules for my data objects in a WPF application. I'm writing them in the configuration file, and so far they are working fine. I'm stumped on how to localize the messages using messageTemplateResourceName and messageTemplateResourceType. What I know is that the strings can be writen in a resource file, given a name and referenced by that name. I get the idea, but i haven't been able to make this work. <ruleset name="Rule Set"> <properties> <property name="StringValue"> <validator lowerBound="0" lowerBoundType="Ignore" upperBound="25" upperBoundType="Inclusive" negated="false" messageTemplate="" messageTemplateResourceName="msg1" messageTemplateResourceType="Resources" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.StringLengthValidator, Microsoft.Practices.EnterpriseLibrary.Validation" name="String Length Validator" /> </property> </properties> </ruleset> Where is the resource file and what value do I pass to messageTemplateResourceType? I have tried writing the messages in the shell project's resource file but no sucess trying to retrieve the value. I only get the default built-in message. I've tried messageTemplateResourceType="typeof(Resources)" messageTemplateResourceType="Resources" messageTemplateResourceType="Resources.resx" messageTemplateResourceType="typeof(Shell)" messageTemplateResourceType="Shell" messageTemplateResourceType="Shell, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" I've also tried adding a new resource file in the shell project, and adding a resource file to the data object's library. I'm all out of ideas Does anyone have any suggestions? I'm not even married to the idea of resource files, so if there are other ways to localize these messages I'd love to know! thanks

  • find word and score based on positions

    - by ryder1211212
    hey guys i have a textfile i have divided it into 4 parts. i want to search each part for the words that appear in each part and score that word exmaple welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. i will want to return national = 1 as it appears only in one part etc am working on determining text context using word position. am working with c# and not very good in text processing basically if a word appears in the 4 sections it scores 4 if a word appears in the 3 sections it scores 3 if a word appears in the 2 sections it scores 2 if a word appears in the 1 section it scores 1 thanks in advance so far i have this var s = "welcome to the national basketball finals,the basketball teams here today have come a long way. without much delay lets play basketball. "; var numberOfParts = 4; var eachPartLength = s.Length / numberOfParts; var parts = new List<string>(); var words = Regex.Split(s, @"\W").Where(w => w.Length > 0); // this splits all words, removes empty strings var wordsIndex = 0; for (int i = 0; i < numberOfParts; i++) { var sb = new StringBuilder(); while (sb.Length < eachPartLength && wordsIndex < words.Count()) { sb.AppendFormat("{0} ", words.ElementAt(wordsIndex)); wordsIndex++; } // here you have the part Response.Write("[{0}]"+ sb); parts.Add(sb.ToString()); var allwords = parts.SelectMany(p => p.Split(' ').Distinct()); var wordsInAllParts = allwords.Where(w => parts.All(p => p.Contains(w))).Distinct();

  • Trying to find a PHP5 API-based embeddable CMS

    - by StrangeElement
    I've been making the rounds for a CMS that I can use as an API, in a sort of "embedded" mode. I mean by this that I don't want the CMS to do any logic or presentation. I want it to be used as an API, which I can then use within an existing site. I don't want to be tied to the architecture of the CMS. A good example of this is NC-CMS (http://www.nconsulting.ca/nc-cms/). All it needs is an include at the top, then wherever editable content is desired it's only a function call with a unique label. It's also perfect in the sense that it allows to differentiate between small strings (like titles, labels) and texts (which require a rich-text editor). It's the only CMS I found that fits this description, but it is a little too light as it does not handle site structure. I need to be able to allow my client to add pages, choosing an existing template for the layout. A minimal back-end is required. Wordpress also fits some requirements in that it handles only content editing and allows freedom for the themes by letting them call the content where and how they want it. But it is article-based and backwards, in that it embeds sites (as themes) within its structure, rather than being embeddable in sites like NC. It's funny how checking out all the CMS out there, almost all of them claim that most CMS are not self-sufficient, that they do not handle application logic, while (almost) every single on I found with only one exception do so. Many are mostly article-based blog engines, which does not fit my need. I would appreciate any CMS that fits the general description.

  • background-color hex to js variable (jquery)

    - by Ezdaroth
    I'm kinda new to javascript and jquery and now I'm facing a problem: I need to post some data to php and one bit of the data needs to be the background color hex of div X. Jquery has css("background-color") function and with it I can get rgb value of the background into a javascript variable. The css function seems to return a string like this rgb(0, 70, 255). I couldn't find any way to get hex of the background-color (even tho it's set as hex in css). So it seems like I need to convert it. I found a function for converting rgb to hex, but it needs to be called with three different variables, r, g and b. So I would need to parse the string rgb(x,xx,xxx) into var r=x; var g=xx; var b=xxx; somehow. I tried to google parsing strings with javascript, but didn't really understand the regular expressions thing. Could someone tell me if there's a way to get background-color of div as hex, or explain how to convert the string into 3 different variables.

  • An Ideal Keyboard Layout for Programming

    - by Jon Purdy
    I often hear complaints that programming languages that make heavy use of symbols for brevity, most notably C and C++ (I'm not going to touch APL), are difficult to type because they require frequent use of the shift key. A year or two ago, I got tired of it myself, downloaded Microsoft's Keyboard Layout Creator, made a few changes to my layout, and have not once looked back. The speed difference is astounding; with these few simple changes I am able to type C++ code around 30% faster, depending of course on how hairy it is; best of all, my typing speed in ordinary running text is not compromised. My questions are these: what alternate keyboard layouts have existed for programming, which have gained popularity, are any of them still in modern use, do you personally use any altered layout, and how can my layout be further optimised? I made the following changes to a standard QWERTY layout. (I don't use Dvorak, but there is a programmer Dvorak layout worth mentioning.) Swap numbers with symbols in the top row, because long or repeated literal numbers are typically replaced with named constants; Swap backquote with tilde, because backquotes are rare in many languages but destructors are common in C++; Swap minus with underscore, because underscores are common in identifiers; Swap curly braces with square brackets, because blocks are more common than subscripts; and Swap double quote with single quote, because strings are more common than character literals. I suspect this last is probably going to be the most controversial, as it interferes the most with running text by requiring use of shift to type common contractions. This layout has significantly increased my typing speed in C++, C, Java, and Perl, and somewhat increased it in LISP and Python.

  • drupal: standard way for creating a slug from a string

    - by egarcia
    Hi there, A slug on this context is a string that its safe to use as an identifier, on urls or css. For example, if you have this string: I'd like to eat at McRunchies! Its slug would be: i-d-like-to-eat-at-mcrunchies- I want to know whether there's a standard way of building such strings on Drupal (or php functions available from drupal). More precisely, inside a Drupal theme. Context: I'm modifying a drupal theme so the html of the nodes it generates include their taxonomy terms as css classes on their containing div. Trouble is, some of those terms' names aren't valid css class names. I need to "slugify" the them. I've read that some people simply do this: str_replace(" ", "-", $term->name) This isn't really a enough for me. It doesn't replace uppercase letters with downcase, but more importantly, doesn't replace non-ascii characters (like à or é) by their ascii equivalents. Is there a function in drupal 6 (or the php libs) that provides a way to slugify a string, and can be used on a template.php file of a drupal theme?

  • How to retrieve the Description property from SettingsProperty?

    - by BadNinja
    For each item in my application's settings, I've added text to its Description Property which I want to retrieve at runtime. I'm sure I'm missing some basic logical nuance here, but everything I've tried has failed. Clearly, my understanding of what value needs to be passed to the Attributes property of the SettingsProperty class is wrong. I'm further confused by the fact that when I iterate through all they keys returned by SettingsProperty.Attributes.Keys, I can see "System.Configuration.SettingsDescriptionAttribute", but when I pass that string in as the key to the Attributes property, null is returned. Any insight into how to properly retrieve the value Description Property would be very much appreciated. Thanks. :) public void MyMethod() { SettingsPropertyCollection MyAppProperties = Properties.Settings.Default.Properties; IEnumerator enumerator = MyAppProperties.GetEnumerator(); // Iterate through all the keys to see what we have.... while (enumerator.MoveNext()) { SettingsProperty property = (SettingsProperty)enumerator.Current; ICollection myKeys = property.Attributes.Keys; foreach (object theKey in myKeys) System.Diagnostics.Debug.Print(theKey.ToString()); // One of the keys returned is: System.Configuration.SettingsDescriptionAttribute } enumerator.Reset(); while (enumerator.MoveNext()) { SettingsProperty property = (SettingsProperty)enumerator.Current; string propertyValue = property.DefaultValue.ToString(); // This fails: Null Reference string propertyDescription = property.Attributes["System.Configuration.SettingsDescriptionAttribute"].ToString(); // Do stuff with strings... } }

  • SQL using sum to count results of multiple subqueries

    - by asdas
    I have a table with 2 columns: integer and var char. I am given only the integer values but need to do work on the var char (string) values. Given an integer, and a list of other integers (no overlap), I want to find the string for that single integer. Then I want to take that string and do the INSTR command with that string, and all the other strings for all the other integers. Then I want the sum of all the INSTR so the result is one number. So lets say I have int x, and list y=[y0, y1, y2]. I want to do 3 INSTR commands like SUM(INSTR(string for x, string for y0), INSTR(string for x, string for y1), INSTR(string for x, string for y2)) I think im going in the wrong direction, this is what I have. Im not good with sub queries. SELECT SUM ( SELECT INSTR ( SELECT string FROM pages WHERE int=? LIMIT 1, ( SELECT string FROM pages WHERE id=? OR id=? OR id=? LIMIT 3 ) ) )

  • Strange Behaviour in Swift: constant defined with LET but behaving like a variable defined with VAR

    - by Sam
    Stuck on the below for a day! Any insight would be greatly appreciated. The constant in the first block match0 behaves as expected. The constant defined in the second block does not behave as nicely in the face of a change to its "source": var str = "+y+z*1.0*sum(A1:A3)" if let range0 = str.rangeOfString("^\\+|^\\-|^\\*|^\\/", options: NSStringCompareOptions.RegularExpressionSearch){ let match0 = str[range0] println(match0) //yields "+" - as expexted str.removeRange(range0) println(match0) //yields "+" - as expected str.removeRange(range0) println(match0) //yields "+" - as expected } if let range1 = str.rangeOfString("^\\+|^\\-|^\\*|^\\/", options: NSStringCompareOptions.RegularExpressionSearch){ let match1 = str[range1] println(match1) //yields "+" as expected str.removeRange(range1) println(match1) //!@#$ OMG!!!!!!!!!!! a constant variable has changed! This prints "z" } The following are the options I can see: match1 has somehow obtained a reference to its source instead of being copied by value [Problem: Strings are value types in Swift] match1 has somehow obtained a closure to its source instead of just being a normal constant/variable? [Problem: sounds like science fiction & then why does match0 behave so well?] Could there be a bug in the Swift compiler? [Problem: Experience has taught me that this is very very very rarely the solution to your problem...but it is still in beta]

  • [F#] Parallelize code in nested loops

    - by Juliet
    You always hear that functional code is inherently easier to parallelize than non-functional code, so I decided to write a function which does the following: Given a input of strings, total up the number of unique characters for each string. So, given the input [ "aaaaa"; "bbb"; "ccccccc"; "abbbc" ], our method will returns a: 6; b: 6; c: 8. Here's what I've written: (* seq<#seq<char>> -> Map<char,int> *) let wordFrequency input = input |> Seq.fold (fun acc text -> (* This inner loop can be processed on its own thread *) text |> Seq.choose (fun char -> if Char.IsLetter char then Some(char) else None) |> Seq.fold (fun (acc : Map<_,_>) item -> match acc.TryFind(item) with | Some(count) -> acc.Add(item, count + 1) | None -> acc.Add(item, 1)) acc ) Map.empty This code is ideally parallelizable, because each string in input can be processed on its own thread. Its not as straightforward as it looks since the innerloop adds items to a Map shared between all of the inputs. I'd like the inner loop factored out into its own thread, and I don't want to use any mutable state. How would I re-write this function using an Async workflow?

  • Substrings, timer and LED lights, as3

    How would I sync my timer with my LED lights? I don't understand how to to set up the strings and conditions, so that they are unique to each number space.

  • How to select all options from a drop list in php / mysql

    - by Mirage81
    Thanks to stackoverflow.com's frienly experts I've managed to create my first php + mysql application. The code searches a mysql database for last names and cities. The choices are made through two drop lists like these: Choose city: All cities Liverpool Manchester Choose last name: All last names Lennon Gallagher The code would return eg. all the Lennons living in Liverpool. However, I haven't been able to make the options "All cities" and "All last names" to work so that the code would return eg. all the Lennons living in any city or all the people living in Liverpool. So, how can that be done? The code so far: index.php <?php $conn = mysql_connect('localhost', 'user', 'password') or die("Connection failed"); mysql_select_db("database", $conn) or die("Switch database failed"); //this gets the cities from the database to the drop list $query = "SELECT DISTINCT city FROM user".mysql_real_escape_string($city); $result = mysql_query($query, $conn); $options=""; while ($row=mysql_fetch_array($result)) { $city=$row["city"]; $options.="<OPTION VALUE=\"$city\">".$city; } //this gets the last names from the database to the drop list $query2 = "SELECT DISTINCT lastname FROM user".mysql_real_escape_string($lastname); $result2 = mysql_query($query2, $conn); $options2=""; while ($row2=mysql_fetch_array($result2)) { $lastname=$row2["lastname"]; $options2.="<OPTION VALUE=\"$lastname\">".$lastname; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <meta content="text/html; charset=ISO-8859-1" http-equiv="content-type"> <title>test</title> </head> <body> <form action="get.php" method="post"> <p> <select name="city"> <option value=0>Choose <option value=1>All cities <?=$options?> </select> </p> <p> <select name="lastname"> <option value=0>Choose <option value=1>All last names <?=$options2?> </select> </p> <p> <input value="Search" type="submit"> </p> </form> <br> </body> </html> get.php <?php $conn = mysql_connect('localhost', 'user', 'password') or die("Connection failed"); mysql_select_db("database", $conn) or die("Switch database failed"); $query = "SELECT * FROM user WHERE city = '".mysql_real_escape_string($_POST['city'])."' AND lastname = '".mysql_real_escape_string($_POST['lastname'])."'"; $result = mysql_query($query, $conn); echo $rowcount; $zerorows=true; while ($row = mysql_fetch_assoc($result)) { $zerorows=false; echo '<b>City: </b>'.htmlspecialchars($row[city]).'<br />'; echo '<b>Last name: </b>'.htmlspecialchars($row[lastname]).'<br />'; echo '<b>Information: </b>'.htmlspecialchars($row[information]).'<br />'.'<br />'; } if($zerorows) echo "No results"; mysql_close($conn); ?>

  • C++ std::stringstream seemingly causes thread to hang or die under SunOS

    - by stretch
    I have an application developed under Linux with GCC 4.2 which makes quite heacy use of stringstreams to wrap and unwrap data being sent over the wire. (Because the Grid API I'm using demands it). Under Linux everything is fine but when I deploy to SunOS (v5.10 running SPARC) and compile with GCC 3.4.6 the app hangs when it reaches the point at which stringstreams are used. In more detail: The main thread accepts requests from clients and starts a new pthread to handle each request. The child thread uses stringstreams to pack data. When the child thread gets to that point it seems to hang for a second and then die. The main thread is unaffected. Are there any known issues with stringstream and GCC 3.4.6 or SunOS or SPARCs? I didn't find anything yet... Can anyone suggest a better way to pack and unpack large amounts of data a strings or byte streams? Apologies for not posting code but this to me seems more involved than a simple syntax error. All the same, the thread crashes: std::stringstream mystringstream; //not here mystringstream << "some data: "; //but here That is, I can declare the stringstream but when I try to use it something goes wrong.

  • How to escape HTML.

    - by kokila
    I have a string which contains HTML text. I need to escape just the strings and not tags. For example, I have string which contains, <ul class="main_nav"> <li> <a class="className1" id="idValue1" tabindex="2">Test & Sample</a> </li> <li> <a class="className2" id="idValue2" tabindex="2">Test & Sample2</a> </li> </ul> How to escape just the text to, <ul class="main_nav"> <li> <a class="className1" id="idValue1" tabindex="2">Test &amp; Sample</a> </li> <li> <a class="className2" id="idValue2" tabindex="2">Test &amp; Sample2</a> </li> </ul> with out modifying the tags. Can this be handled with HTML DOM and javascript? Thanks
