  • Validating String Characters as Numeric w/ Pascal (FastReport 4)

    - by user2525015
    I'm new to Pascal and FastReport. This question can probably be answered without knowledge of FastReport. Pascal is Delphi. FastReport4. I have a text box accepting an 8 character string as input. Each character should be numeric. I'm attempting to validate each character as numeric. I've tried using the val function... Procedure Val(S : String; var R: Real; Code : Integer); begin end; procedure thisinputOnChange(Sender: TfrxComponent); var S : String; error : Integer; R : Real; begin S := thisinput.lines.text; Val (S, R, error); If error > 0 then Button2.enabled := False; end; I got this code online. The explanation says that the function will return an error with a code greater than zero if the character cannot be converted to an integer. Is that explanation correct? Am I misinterpreting? Right now I am trying to set a button's enabled property to false if the validation fails. I might change that to a message. For now, I would like to get it to work by setting the button property. I'm not sure if I should be using the onChange event or another event. I'm also not sure if I need to send the input to the val function in a loop. Like I said, I'm just learning how to use this function. I am able to validate the length. This code works... procedure thisinputOnChange(Sender: TfrxComponent); begin if length(thisinput.lines.text) = 8 then Button2.enabled := True; end; Any suggestions? Should I use the val function or something else? Let me know if I need to provide more info. I might not be able to check back until later, though. Thanks for any help.

  • Why use a whitelist for HTML sanitizing?

    - by Carson Myers
    I've often wondered -- why use a whitelist as opposed to a blacklist when sanitizing HTML input? How many sneaky HTML tricks are there to open XSS vulnerabilities? Obviously script tags and frames are not allowed, and a whitelist would be used on the fields in HTML elements, but why disallow most of everything?

  • Generating a list of values a regex COULD match in Python

    - by mlissner
    I'm trying to use a regex as an input, and from there generate all the possible values that the regex would match. So, for example, if the regex is "three-letter words starting with a, and ending in c," then the code would generate a list with the values [aac, abc, acc, adc, a1c....]. Is there an easy way to do this? I'm using python.

  • jQuery and XML (with CDATA)

    - by P..
    I've seen the post that deal with this issue but I still can't solve my issue: I've got XML with CDATA and when I parse the XML, it includes the CDATA (which I don't want). XML sample: <mainnav> <nav path="/" xmlpath="home.xml" key="footer" navigator=""> <display><![CDATA[Home]]></display> <title><![CDATA[Home]]></title> </nav> <nav path="/nav1/" xmlpath="nav1.xml" key="primary" navigator="primary" iconid="0"> <display><![CDATA[Nav 1]]></display> <title><![CDATA[Nav 1]]></title> <overdesc><![CDATA[test nav 1]]></overdesc> <sub path="/nav1/sub1/" xmlpath="nav1/sub1.xml" key="sub"> <display><![CDATA[sub 1<br />of nav 1]]></display> <title><![CDATA[sub 1<br />of nav 1]]></title> </sub> </nav> <nav path="/nav1/" xmlpath="nav2.xml" key="primary" navigator="primary" iconid="1"> <display><![CDATA[Nav 2]]></display> <title><![CDATA[Nav 2]]></title> <overdesc><![CDATA[test nav 2]]></overdesc> <sub path="/nav2/sub1/" xmlpath="nabv2/sub1.xml" key="sub"> <display><![CDATA[sub 1<br />of nav 2]]></display> <title><![CDATA[sub 1<br />of nav2]]></title> </sub> </nav> </mainnav> jQuery: $(document).ready(function(){ $.ajax({ type: "GET", url: "site_xml/config.xml", //contentType: "text/xml", dataType: ($.browser.msie) ? "xml" : "text/xml", success: parseXML, error: function(XMLHttpRequest, textStatus, errorThrown) { alert(errorThrown); } });}); function parseXML(xml) { $(xml).find('nav').each(function(){ if ($(this).attr("key")=="primary") { // this is a primary nav item; var title = $.trim( $(this).find('title').text() ); alert(title); $("#output").append(title); //nothing showing up in my output DIV, presumably due to the CDATA tags? } }); }

  • Creating a post-build step in Xcode 3.2

    - by jsheehy
    I'm actually looking for a genuine "post build" phase - not the Run script stage. The reason for this is that I want to do some parsing of a target's build-state.dat which is where Xcode puts all of its build output. The problem is that this file isn't actually created until after the build has succeeded or failed, thus anything in the Run Script phase can't see it. Any clues? Thanks

  • Font Anti-Aliasing on iPad SDK

    - by Felix Khazin
    I'm using a custom pixel font on the iPad SDK, and I'm trying to find a way to disable font anti-aliasing for UIFont. Pixel fonts usually work best when they don't have Anti-aliasing. I disable it easily in Photoshop when I create static resources, but this time I need a dynamic output with the custom font. Any ideas? Thanks.

  • Best way to get all digits from a string with regex

    - by Chris Marisic
    Is there any better way to get take a string such as "(123) 455-2344" and get "1234552344" from it than doing this: var matches = Regex.Matches(input, @"[0-9]+", RegexOptions.Compiled); return String.Join(string.Empty, matches.Cast<Match>() .Select(x => x.Value).ToArray()); Perhaps a regex pattern that can do it in a single match? I couldn't seem to create one to achieve that though.

  • Replace this Hex chars from string in PHP

    - by Guillermo
    I'm generating an XML from data that comes from database (and some JSON feeds). I'm having some problems with some texts that contains some hex chars that are breaking my XML. For example, see this screenshot of the error I get from Chrome: I identified the hex characters that are giving me problems (I believe they're called control characters). And these are: 0x03 0x05 0x16 0x0E How can I replace those characters with PHP before printing them on my XML output? Thanks!

  • PHP: Can pcntl_alarm() and socket_select() peacefully exist in the same thread?

    - by DWilliams
    I have a PHP CLI script mostly written that functions as a chat server for chat clients to connect to (don't ask me why I'm doing it in PHP, thats another story haha). My script utilizes the socket_select() function to hang execution until something happens on a socket, at which point it wakes up, processes the event, and waits until the next event. Now, there are some routine tasks that I need performed every 30 seconds or so (check of tempbanned users should be unbanned, save user databases, other assorted things). From what I can tell, PHP doesn't have very great multi-threading support at all. My first thought was to compare a timestamp every time the socket generates an event and gets the program flowing again, but this is very inconsistent since the server could very well sit idle for hours and not have any of my cleanup routines executed. I came across the PHP pcntl extensions, and it lets me use assign a time interval for SIGALRM to get sent and a function get executed every time it's sent. This seems like the ideal solution to my problem, however pcntl_alarm() and socket_select() clash with each other pretty bad. Every time SIGALRM is triggered, all sorts of crazy things happen to my socket control code. My program is fairly lengthy so I can't post it all here, but it shouldn't matter since I don't believe I'm doing anything wrong code-wise. My question is: Is there any way for a SIGALRM to be handled in the same thread as a waiting socket_select()? If so, how? If not, what are my alternatives here? Here's some output from my program. My alarm function simply outputs "Tick!" whenever it's called to make it easy to tell when stuff is happening. This is the output (including errors) after allowing it to tick 4 times (there were no actual attempts at connecting to the server despite what it says): [05-28-10 @ 20:01:05] Chat server started on 192.168.1.28 port 4050 [05-28-10 @ 20:01:05] Loaded 2 users from file PHP Notice: Undefined offset: 0 in /home/danny/projects/PHPChatServ/ChatServ.php on line 112 PHP Warning: socket_select(): unable to select [4]: Interrupted system call in /home/danny/projects/PHPChatServ/ChatServ.php on line 116 [05-28-10 @ 20:01:15] Tick!

    I have a web service file in my project having a web method which is used for AutoCompleteExtender and which works fine when I debug it from VS. But when I publish and host it on IIS, it's not working properly. However, I tested the webservice method directly by typing the URL and it gave the desired output. Is their a special setting needs to be done in IIS to make it working or any property of AutoCompleteExtender need to be set?
