• a potentially dangerous request.form value was detected but validateinput(false) not working

  - by tonybolding

  I have installed VS2010 and MVC2 and testing a simple form using tinyMCE. When I post the contents of the textarea in tinyMCE I get the dreaded YSD and the message "a potentially dangerous....." No problem I thought - seen this before so I put the ValidateInput(false) on the controller but no joy - I still get the error. page code in edit.aspx is: <% using (Html.BeginForm()){ % <!-- Gets replaced with TinyMCE, remember HTML in a textarea should be encoded --> <textarea id="elm1" name="mceText" rows="15" cols="80" style="width: 80%"> &lt;p&gt; This is some example text that you can edit inside the &lt;strong&gt;TinyMCE editor&lt;/strong&gt;. </textarea> <br /> <input type="submit" name="save" value="Submit" /> <input type="reset" name="reset" value="Reset" /> <%} % and Controller action is: [AcceptVerbs(HttpVerbs.Post)] [ValidateInput(false)] public ActionResult Edit(string mceText) { return View(); } Any thoughts - (I know the code is not complete) been trying this for hours but everyone just says to use ValidateInput(false)

• Objective-C Result from a Static Method saved to class instance variable giving "EXC_BAD_ACCESS" when used.

  - by KinGBin

  I am trying to store the md5 string as a class instance variable instead of the actual password. I have a static function that will return a md5 string which I'm trying to store in an instance variable instead of the actual password. I have the following setter for my class instance variable: -(void)setPassword:(NSString *)newpass{ if(newpass != password){ password = [utils md5HexDigest:newpass]; } } This will pass back the correct md5 string and save it to the password variable in my init function: [self setPassword:pword];. If I call another instance method and try to access self.password" I will get "EXC_BAD_ACCESS". I understand that the memory is getting released, but I have no clue to make sure it stays. I have tried alloc init with autorelease with no luck. This is the md5HexDigest function getting called during the init (graciously found in another stackoverflow question): + (NSString*)md5HexDigest:(NSString*)input { const char* str = [input UTF8String]; unsigned char result[CC_MD5_DIGEST_LENGTH]; CC_MD5(str, strlen(str), result); NSMutableString *ret = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH*2]; for(int i = 0; i<CC_MD5_DIGEST_LENGTH; i++) { [ret appendFormat:@"%02x",result[i]]; } return ret; } Any help/pointers would be greatly appreciated. I would rather have the md5 string saved in memory than the actual password calling the md5 every time I needed to use the password. Thanks in advance.

• Array loading with doubles in C

  - by user2892120

  I am trying to load a 3x8 array of doubles but my code keeps outputting 0.00 for all of the values. The code should be outputting the array (same as the input) under the Read#1 Read#2 Read#3 lines, with the average under average. Here is my code: #include <stdio.h> double getAvg(double num1, double num2, double num3); int main() { int numJ,month,day,year,i,j; double arr[3][8]; scanf("%d %d %d %d",&numJ,&month,&day,&year); for (i = 0; i < 8; i++) { scanf("%f %f %f",&arr[i][0], &arr[i][1], &arr[i][2]); } printf("\nJob %d Date: %d/%d/%d",numJ,month,day,year); printf("\n\nLocation Read#1 Read#2 Read#3 Average"); for (j = 0; j < 8; j++) { printf("\n %d %.2f %.2f %.2f %.2f",j+1,arr[j][0],arr[j] [1],arr[j][2],getAvg(arr[j][0],arr[j][1],arr[j][2])); } return 0; } double getAvg(double num1, double num2, double num3) { double avg = (num1 + num2 + num3) / 3; return avg; } Input example: 157932 09 01 2013 0.00 0.00 0.00 0.36 0.27 0.23 0.18 0.16 0.26 0.27 0.00 0.34 0.24 0.00 0.31 0.16 0.33 0.36 0.29 0.36 0.00 0.21 0.36 0.00

• Find class in table row

  - by meep

  Hello. Take a look at this table: <table cellpadding="0" cellspacing="0" class="order_form"> <tr> <th>Amount</th> <th>Desc</th> <th>Price</th> <th>Total</th> </tr> <tr> <td><input type="text" class="order_count" /></td> <td> <span class="order_desc">Middagstallerken</span> </td> <td> <span class="order_price">1,15</span> </td> <td> <span class="order_each_total"></span> </td> </tr> [...] </table> Upon entering amount I need to select the class "order_price" and multiply it with the value of the input "order_count" and place it in "order_each_count". I have millions of these rows so I need to find the next class in the row. I have tried using some function like this but without result: <script type="text/javascript"> $(document).ready(function(){ $('.order_count').keyup(function() { var each_price = $(this).prevUntil("tr").find("span.order_price").text(); }); }); </script> I hope someone have a good solution :-)

• Cancel text selection on textinput in Flex

  - by Michael

  So the real problem is the lack of an onReleaseOutside function. I found some examples of how to bypass this during a drag function but it was not applicable for a text input. The problem is that when a user selects some text in textinput and mouses off the application area and then mouses up, I'm getting a problem that the textinput keeps thinking that the mouse down is actively selecting text in the textinput and continually overwrites the characters being entered in the textinput. You can test this at http://palermo.infusedindustries.com [ in the search bar of the live store on the page, type some text, then highlight it all and don't let up on the mouse until you are outside the store. I finally hacked some junk together so I can tell if the mouse goes off the stage using some code like var x = stage.mouseX; var y = stage.mouseY; if(x < 0 || y <0 || x >stage.stageWidth || y > stage.stageHeight) I'd like to just make the textinput stop thinking it should be highlighting text so that even if the user scrolls out of the applet and mouses up that the text input still overwrites what is in the search bar and functions as normal. I can't seem to find any events or ways to tell the Flex text field to stop thinking that the mouse is down and that the user is done selecting text.

• Finding the unique paths through a Neo4j graph

  - by Larry

  I have a Neo4j graph with 12 inputs and 4 outputs, and am trying to write a query with the Java Traverser that will return the 14 unique paths from an input to an output node. All the queries I have tried return only a subset of the 14 paths. For example, the code below returns 4 paths, but the other 10 all stop 1 node short of the output. RelationshipType relType = RelationshipTypes.EDGE; TraversalDescription td = new TraversalDescriptionImpl() .depthFirst() .relationships(relType, Direction.OUTGOING); for (Node node : inputs){ Traverser tv = td.traverse(node); Iterator<Path> iter = tv.iterator(); // ... print path } I've tried uniqueness and depth settings as well, with no effect. The query below returns all 14 paths using the web interface, but when I use the ExecutionEngine class, I only get 13 paths back. START s=node(*) MATCH (s)-[p:EDGE*]->(c) WHERE s.type! = "INPUT" AND c.type! = "OUTPUT" RETURN p How do I get all the unique paths using the Java API?

• Is it possible to access the SMIL timer from javascript?

  - by Will

  I'm trying to use SMIL to animate the typing of text into a field embedded in a SVG. I tried the following code in both Chrome and a SMIL-enable Firefox nightly, but it has no effect: <svg xmlns="http://www.w3.org/2000/svg" xmlns:html="http://www.w3.org/1999/xhtml"> <foreignObject> <html:input type="text" value=""> <set attributeName="value" to="Hello World" begin="0" dur="10s" fill="freeze" /> </html:input> </foreignObject> </svg> The text field appears, but remains empty. So, I thought I would register for the beginEvent and do the substitution manually. To test the events, I added: <rect id="rect" x="0" y="0" width="10" height="10"> <animate id="dx" attributeName="x" attributeType="XML" begin="0s" dur="1s" fill="freeze" from="0" to="-10" /> </rect> As well as the javascript that made sense from the event model: window.addEventListener( 'load', function() { function listen( id ) { var elem = document.getElementById( id ) elem.addEventListener( 'beginEvent', function() { console.log( 'begin ' + id ) }, false ) elem.addEventListener( 'endEvent', function() { console.log( 'end ' + id ) }, false ) } listen( 'rect' ) listen( 'dx' ) }) But there's no events fired on either the rect or the animate in either browser. The next logical step seems to be to simulate the animation (ala. FakeSmile), but I want to use the browser's animation timer if at all possible.

• Python client / server question

  - by AustinM

  I'm working on a bit of a project in python. I have a client and a server. The server listens for connections and once a connection is received it waits for input from the client. The idea is that the client can connect to the server and execute system commands such as ls and cat. This is my server code: import sys, os, socket host = '' port = 50105 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) s.bind((host, port)) print("Server started on port: ", port) s.listen(5) print("Server listening\n") conn, addr = s.accept() print 'New connection from ', addr while (1): rc = conn.recv(5) pipe = os.popen(rc) rl = pipe.readlines() file = conn.makefile('w', 0) file.writelines(rl[:-1]) file.close() conn.close() And this is my client code: import sys, socket s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) host = 'localhost' port = input('Port: ') s.connect((host, port)) cmd = raw_input('$ ') s.send(cmd) file = s.makefile('r', 0) sys.stdout.writelines(file.readlines()) When I start the server I get the right output, saying the server is listening. But when I connect with my client and type a command the server exits with this error: Traceback (most recent call last): File "server.py", line 21, in <module> rc = conn.recv(2) File "/usr/lib/python2.6/socket.py", line 165, in _dummy raise error(EBADF, 'Bad file descriptor') socket.error: [Errno 9] Bad file descriptor On the client side, I get the output of ls but the server gets screwed up.

• Optimising ruby regexp -- lots of match groups

  - by Farcaller

  I'm working on a ruby baser lexer. To improve performance, I joined up all tokens' regexps into one big regexp with match group names. The resulting regexp looks like: /\A(?<__anonymous_-1038694222803470993>(?-mix:\n+))|\A(?<__anonymous_-1394418499721420065>(?-mix:\/\/[\A\n]*))|\A(?<__anonymous_3077187815313752157>(?-mix:include\s+"[\A"]+"))|\A(?<LET>(?-mix:let\s))|\A(?<IN>(?-mix:in\s))|\A(?<CLASS>(?-mix:class\s))|\A(?<DEF>(?-mix:def\s))|\A(?<DEFM>(?-mix:defm\s))|\A(?<MULTICLASS>(?-mix:multiclass\s))|\A(?<FUNCNAME>(?-mix:![a-zA-Z_][a-zA-Z0-9_]*))|\A(?<ID>(?-mix:[a-zA-Z_][a-zA-Z0-9_]*))|\A(?<STRING>(?-mix:"[\A"]*"))|\A(?<NUMBER>(?-mix:[0-9]+))/ I'm matching it to my string producing a MatchData where exactly one token is parsed: bigregex =~ "\n ... garbage" puts $~.inspect Which outputs #<MatchData "\n" __anonymous_-1038694222803470993:"\n" __anonymous_-1394418499721420065:nil __anonymous_3077187815313752157:nil LET:nil IN:nil CLASS:nil DEF:nil DEFM:nil MULTICLASS:nil FUNCNAME:nil ID:nil STRING:nil NUMBER:nil> So, the regex actually matched the "\n" part. Now, I need to figure the match group where it belongs (it's clearly visible from #inspect output that it's _anonymous-1038694222803470993, but I need to get it programmatically). I could not find any option other than iterating over #names: m.names.each do |n| if m[n] type = n.to_sym resolved_type = (n.start_with?('__anonymous_') ? nil : type) val = m[n] break end end which verifies that the match group did have a match. The problem here is that it's slow (I spend about 10% of time in the loop; also 8% grabbing the @input[@pos..-1] to make sure that \A works as expected to match start of string (I do not discard input, just shift the @pos in it). You can check the full code at GH repo. Any ideas on how to make it at least a bit faster? Is there any option to figure the "successful" match group easier?

• Checking Selected Radio Button after POST

  - by coffeeaddict

  I've been using ASP.NET controls which perform a lot of the manual for you. But I'm going back to the basics, what everyone else does. I'm using standard input tags. So for example if I have a radio button group and I select a button. When the form submits and does a POST back to whatever action="MyPage.aspx" then to grab and check the radio button's value that was selected is it always done like this below? <label><input type="radio" name="rbGroup" value='<%# ((Action)Container.DataItem).ID %>'/><%# ((Action)Container.DataItem).Name %></label> So here I'm appending the ID to the value. And then when it hits the page that my action specifies, I'm checking to see which was selected by trimming off and getting that ID from the value: string selection = Request.Form["rbGroup"]; string dbRecordIdSelected = int.Parse(selection.Substring(1)); so now I can check the id they selected...that is the ID of the db record that gave that selected radio it's name. Is that how you basically always check what radio was selected by checking the name/value pair that comes across for that selected radioButton group name? And then you can append stuff like IDs or whatever you want to grab and parse out to then do additional logic on the server-side once that header reaches the server and your specified page in the action attribute? The above code is not production code, just something to explain what I'm talking about.

• C read X bytes from a file, padding if needed

  - by Hunter McMillen

  I am trying to read in an input file 64 bits at a time, then do some calculations on those 64 bits, the problem is I need to convert the ascii text to hexadecimal characters. I have searched around but none of the answers posted seem to work for my situation. Here is what I have: int main(int argc, int * argv) { char buffer[9]; FILE *f; unsigned long long test; if(f = fopen("input2.txt", "r")) { while( fread(buffer, 8, 1, f) != 0) //while not EOF read 8 bytes at a time { buffer[8] = '\0'; test = strtoull(buffer, NULL, 16); //interpret as hex printf("%llu\n", test); printf("%s\n", buffer); } fclose(f); } } For an input like this: "testing string to hex conversion" I get results like this: 0 testing 0 string t 0 o hex co 0 nversion Where I would expect: 74 65 73 74 69 6e 67 20 <- "testing" in hex testing 73 74 72 69 6e 67 20 74 <- "string t" in hex string t 6f 20 68 65 78 20 63 6f <- "o hex co" in hex o hex co 6e 76 65 72 73 69 6f 6e <- "nversion" in hex nversion Can anyone see where I misstepped?

• Java Socket - how to catch Exception of BufferedReader.readline()

  - by Hasan Tahsin

  I have a Thread (let's say T1) which reads data from socket: public void run() { while (running) { try { BufferedReader reader = new BufferedReader( new InputStreamReader(socket.getInputStream()) ); String input = reader.readLine(); } catch (IOException e) { e.printStackTrace(); } } } Another Thread (lets say T2) try to finish the program in one of its method. Therefore T2 does the following: T1.running = false; socket.close(); Here is this scenario for which i couldn't find a solution: T1 is active and waiting for some input to read i.e. blocking. context switching T2 is active and sets running to false, closes the socket context switching because T1 was blocking and T2 closed the socket, T1 throws an Exception. What i want is to catch this SocketException. i can't put a try/catch(SocketException) in T1.run(). So how can i catch it in T1's running-method? If it's not possible to catch it in T1's running, then how can i catch it elsewhere? PS: "Another question about the Thread Debugging" Normally when i debug the code step by step, i lose the 'active running line' on a context switch. Let's say i'm in line 20 of T1, context switch happens, let's assume the program continues from the 30.line of T2, but the debugger does not go/show to the 30.line of T2, instead the 'active running line' vanishes. So i lose the control over the code. I use Eclipse for Java and Visual Studio for C#. So what is the best way to track the code while debugging on a context switch ?

• Cant get JavaScipt to check for null objects

  - by CountMurphy

  I really don't know what the issue is here. Far as I can see, the code is simple and should work fine. var Prices=""; for (var PriceCount = 1; PriceCount <= 120; PriceCount++) { var CurrentPrice = "Price" + PriceCount; if (prevDoc.getElementById(CurrentPrice).value != null) { if (Prices == "") { Prices = prevDoc.getElementById(CurrentPrice).value; } else { Prices += "," + prevDoc.getElementById(CurrentPrice).value; } } else { break; } } There could be up to 120 hidden inputs on the form. The moment we check for an input that doesn't exist the loop should break. My test page has two input elements that get pulled. On the third (the null) I get this error in firebug: prevDoc.getElementById(CurrentPrice) is null if (prevDoc.getElementById(CurrentPrice).value != null) { Yes it is null...that's what the check is for ?_? Does any one know what I'm doing wrong? This seems like it should be really straight forward. EDIT: for clarity's sake, prevDoc=window.opener.document

• why doesnt this program print?

  - by Alex

  What I'm trying to do is to print my two-dimensional array but i'm lost.

• RegExpValidator never matches

  - by babyangel86

  Hi, I've got a class that's meant to validate input fields to make sure the value is always a decimal. I've tested the regex here: http://livedocs.adobe.com/flex/3/html/help.html?content=validators_7.html, and it looks like it does the right thing, but in my app, I can't seem to get it to match to a number format. Class Definition: public class DecimalValidator { //------------------------------- ATTRIBUTES public var isDecimalValidator:RegExpValidator; //------------------------------- CONSTRUCTORS public function DecimalValidator() { isDecimalValidator = new RegExpValidator(); isDecimalValidator.expression = "^-?(\d+\.\d*|\.\d+)$"; isDecimalValidator.flags = "g"; isDecimalValidator.required = true; isDecimalValidator.property = "text"; isDecimalValidator.triggerEvent = FocusEvent.FOCUS_OUT; isDecimalValidator.noMatchError = "Float Expected"; } } Setting the source here: public function registerDecimalInputValidator(inputBox:TextInput, valArr:Array):void { // Add Validators var dValidator:DecimalValidator = new DecimalValidator(); dValidator.isDecimalValidator.source = inputBox; dValidator.isDecimalValidator.trigger = inputBox; inputBox.restrict = "[0-9].\\.\\-"; inputBox.maxChars = 10; valArr.push(dValidator.isDecimalValidator); } And Calling it here: registerDecimalInputValidator(textInput, validatorArr); Where textInput is an input box created earlier. Clearly I'm missing something simple yet important, but I'm not entirely sure what! Any help would be much appreciated.

• How to align all fields as label width grows

  - by TheCloudlessSky

  I have a form where the labels are on the left and the fields on the right. This layout works great when the labels have small amounts of text. I can easily set a min-width on the labels to ensure they all have the same distance to the fields. In the first picture below, this works as expected. A problem arises when the label's text becomes too long, it'll either overflow to the next line or push the field on the same line over to the left (as seen in picture 2). This doesn't push the other labels so it is left with a "jagged" look. Ideally, it should like to style it as picture 3 with something like the following markup: <fieldset> <label>Name</label><input type="text" /><br /> <label>Username</label><input type="text" /> </fieldset> I created a jsFiddle to show the issue. Of course, the easy cross-browser way to solve this would be to use tables. That just creates tag-hell for something that should be so simple. Note: this does not need to support IE6.

• Adding dynamic content with events in jquerymobile

  - by Christian Waidner

  Currently I'm stuck with a problem in jquerymobile: I'm adding items to a list dynamically and use enhanceWithin() in the end (so styling is correct). After this I like to add click-events for each list item but the problem is, that enhanceWithin runs asynchronous and so I always get the error message "cannot call methods on checkboxradio prior to initialization; attempted to call method 'refresh'" When I delay the event-adding-code it works perfectly. Does anyone have an idea if there is a enhanceWithin.done event or anything else I can use? HTML: ... <div id="shoppinglist">Loading list...</div> ... Javascript: function updateList() { var result = ""; $.each(shoppinglistItems, function (index, item) { result += '<label><input type="checkbox" ' + item.checked + ' id="item_' + item.id + '">' + item.name + '</label>\n'; }); $('#shoppinglist').html(result).enhanceWithin(); // Change-Events an die Checkboxen knoten $('input[id*=item_]').unbind('change').bind('change', function (event) { var itemid = $(this).attr('id'); itemid = (itemid.split('_'))[1]; // Nur die Zahl extrahieren // Passendes Item aus der Liste der Items suchen und checken $.each(shoppinglistItems, function (index, item) { if (item.id == itemid) { item.checked = "checked"; item.timestamp = moment().format("YYYYMMDDHHmmss"); } }); updateList(); }); }

• Get element id on hover (or mouseover)

  - by Peter C

  Still getting to grips with jQuery and I am pleased to have got as far as I have, especially help from the posts in this forum. However, now got to a working function that does what I want, that is to create a radio group that looks like a button. It pulls data via json and loops through creating the radio buttons. I want to get the id of the radio buttons generated so that I can then parse through to the next step of the app but I can't get it to work. function FillDiv(groups, side) { var cnt = 1; var newClass = ''; var newType = ''; if (side == '#ck-button-left') { newClass = 'leftClass'; newType = 'radio' } else { newClass = 'rightClass'; newType = 'checkbox' } $.each(groups, function (index, groups) { $(side) .append( $(document.createElement('label')).attr({ id: cnt + 'lbl' }) ); $('#' + cnt + 'lbl') .append( $(document.createElement('input')).attr({ id: groups.GroupCode, type: newType, name: 'testGroup', class: newClass }) ); $('#' + groups.GroupCode).after ( $(document.createElement('span')).text(groups.GroupName).attr('class', 'leftSpan') ); $('#' + cnt + 'lbl').after($(document.createElement('br'))); cnt = cnt + 1; }); } Looking through various searched, it should work with something like... $('#leftSpan').mouseover(function () { $('#lblOutput').html(this.id); }); or, as I suspect, it is something to do with the nesting of the label/input that I need to reference the parent or child. Any pointers would be appreciated.

• How to structure data... Sequential or Hierarchical?

  - by Ryan

  I'm going through the exercise of building a CMS that will organize a lot of the common documents that my employer generates each time we get a new sales order. Each new sales order gets a 5 digit number (12222,12223,122224, etc...) but internally we have applied a hierarchy to these numbers: + 121XX |--01 |--02 + 122XX |--22 |--23 |--24 In my table for sales orders, is it better to use the 5 digital number as an ID and populate up or would it be better to use the hierarchical structure that we use when referring to jobs in regular conversation? The only benefit to not populating sequentially seems to be formatting the data later on in my view, but that doesn't sound like a good enough reason to go through the extra work. Thanks

  I have the following: <form name="input" method="get" action="http://site:8083/Default.aspx?DC=" target="foo" onSubmit="window.open('', 'foo', 'width=1100 height=500,status=no,resizable=yes,scrollbars=yes')"> <select name="DC"> <option value="1&Type=type1">1</option> <option value="2&Type=type2">2</option> <option value="3&Type=type3">3</option> <option value="4&Type=type4">4</option> <option value="5&Type=type5">5</option> <option value="6&Type=type6">6</option> <option value="7&Type=type7">7</option> </select> <input type="submit" value=">>"/>&nbsp;&nbsp; </form> Basically my querystring should be something like DC=1&Type=type1 the problem I have is that when I click the button above the html screws up the stirng by changing & to %26 and = to %3D How can I make the value stay as I have it in the code above?

• Why doesn't sed's automatic printing deliver the expected results?

  - by CodeGnome

  What Works This sed script works as intended: $ echo -e "2\n1\n4\n3" | sed -n 'h; n; G; p' 1 2 3 4 It takes pair of input lines at a time, and swaps the lines. So far, so good. What Doesn't Work What I don't understand is why I can't use sed's automatic printing. Since sed automatically prints the pattern space at the end of each execution cycle (except when it's suppressed), why is this not equivalent? $ echo -e "2\n1\n4\n3" | sed 'h; n; G' 2 1 2 4 3 4 What I think the code says is: The input line is copied to the hold space. The next line is read into the pattern space. The hold space is appended to the pattern space. The pattern space (line1 + newline + line2) is printed automatically because we've reached the end of the execution cycle. Obviously, I'm wrong...but I don't understand why. Can anyone explain why this second example breaks, and why print suppression is needed to yield the correct results?

• Convert Markdown text to RTF, using Ruby and Pandoc?

  - by niteshade

  Playing with Ruby and Ruby-Pandoc. Seems like a nice tool, if I can get it to work. I'd like to convert some Markdown text (with embedded lists and other fanciness) to Rich Text. Here's the text I'm converting: Title === This is a paragraph. Hallelujah. Here comes a nested list. --- * List item 1 * List item 1.1 * List item 1.2 * List item 2 * List item 2.1 Here's my Ruby code... require 'pandoc-ruby' input = File.read(test.md) converter = PandocRuby.new(input, from: :markdown, to: :rtf) puts converter.convert ... which (after saving the output to a file) produces a document without anything but a title: Here's the code of the RTF file: {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs36 Title\par} {\pard \ql \f0 \sa180 \li0 \fi0 This is a paragraph. Hallelujah.\par} {\pard \ql \f0 \sa180 \li0 \fi0 \b \fs32 Here comes a nested list.\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.1\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 1.2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2\par} {\pard \ql \f0 \sa0 \li360 \fi-360 \bullet \tx360\tab List item 2.1\sa180\par} In addition, even if it did show up in my RTF viewer (Mac TextEdit), the RTF code seems to have lost all list nesting. I don't know how to diagnose this, whether I have not stated necessary header information or something in Ruby-Pandoc. Thanks in advance!

• Testing variable types in Python

  - by Jasper

  Hello, I'm creating an initialising function for the class 'Room', and found that the program wouldn't accept the tests I was doing on the input variables. Why is this? def __init__(self, code, name, type, size, description, objects, exits): self.code = code self.name = name self.type = type self.size = size self.description = description self.objects = objects self.exits = exits #Check for input errors: if type(self.code) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 110' elif type(self.name) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 111' elif type(self.type) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 112' elif type(self.size) != type(int()): print 'Error found in module rooms.py!' print 'Error number: 113' elif type(self.description) != type(str()): print 'Error found in module rooms.py!' print 'Error number: 114' elif type(self.objects) != type(list()): print 'Error found in module rooms.py!' print 'Error number: 115' elif type(self.exits) != type(tuple()): print 'Error found in module rooms.py!' print 'Error number: 116' When I run this I get this error: Traceback (most recent call last): File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa I/rooms.py", line 148, in <module> myRoom = Room(101, 'myRoom', 'Basic Room', 5, '<insert description>', myObjects, myExits) File "/Users/Jasper/Development/Programming/MyProjects/Game Making Challenge/Europa I/rooms.py", line 29, in __init__ if type(self.code) != type(str()): TypeError: 'str' object is not callable

• jQuery replacement for Default Button or Link

  - by pyccki

  As everyone knows, that default button doesn't work in FF, only IE. I've tried to put in the tag or in the and it's not working. I've found a js script to fix this issue, but for some reason it's not working for me. This script for a submit button, i need to use it for a LinkButton, which is should be the same. Link: <div id="pnl"> <a id="ctl00_cphMain_lbLogin" title="Click Here to LogIn" href="javascript:WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions(&quot;ctl00$cphMain$lbLogin&quot;, &quot;&quot;, true, &quot;Login1&quot;, &quot;&quot;, false, true))">Log In</a> <input name="ctl00$cphMain$UserName" type="text" id="ctl00_cphMain_UserName" /> <input name="ctl00$cphMain$UserName" type="text" id="ctl00_cphMain_UserName1" /> </div> <script> $(document).ready(function() { $("#pnl").keypress(function(e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { $("a[id$='_lbLogin']").click(); return true; } }); }); I know that i can override original function "*WebForm_FireDefaultButton*" in This post, but i really wanted to get this one to work. Thanx in advance!!!
