  • How to invalidate a single data item in the .net cache in VB

    - by Craig
    I have the following .NET VB code to set and read objects in cache on a per user basis (i.e. a bit like session) '' Public Shared Sub CacheSet(ByVal Key As String, ByVal Value As Object) Dim userID As String = HttpContext.Current.User.Identity.Name HttpContext.Current.Cache(Key & "_" & userID) = Value End Sub Public Shared Function CacheGet(ByVal Key As Object) Dim returnData As Object = Nothing Dim userID As String = HttpContext.Current.User.Identity.Name returnData = HttpContext.Current.Cache(Key & "_" & userID) Return returnData End Function I use these functions to hold user data that I don't want to access the DB for all the time. However, when the data is updated, I want the cached item to be removed so it get created again. How do I make an Item I set disappear or set it to NOTHING or NULL? Craig

  • jQuery Datepicker - Programatically Limit Second Datepicker

    - by Dodinas
    Hello all, I've recently been using the following piece of code to limit my 2nd Date picker (end date) so that it does not precede the date of the 1st Date picker. $("#datepicker").datepicker({ minDate: +5, maxDate: '+1M +10D', onSelect: function(dateText, inst){ var the_date = dateText; $("#datepicker2").datepicker('option', 'minDate', the_date); } }); $("#datepicker2").datepicker({ maxDate: '+1M +10D', onSelect: function(dateText, inst){ } }); However, lately, I wanted to format my datepickers using: dateFormat: 'yy-mm-dd' But now, the 2nd datepicker actually allows the user to pick a date 1 day before. For example, if the user picks the 1st date: 2010-04-03, when the 2nd Datepicker pops up, they are able to pick 2010-04-02 (1 day before their first selected date). I do not want the user to be able to pick a date that was before their first selected day. Any ideas why this isn't working after I added in the "dateFormat"?

  • Google Maps Api v3 - getBounds is undefined

    - by Via Lactea
    Hi All, I'm switching from v2 to v3 google maps api and got a problem with gMap.getBounds() function. I need to get the bounds of my map after its initialization. Here is my javascript code: var gMap; $(document).ready( function() { var latlng = new google.maps.LatLng(55.755327, 37.622166); var myOptions = { zoom: 12, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP }; gMap = new google.maps.Map(document.getElementById("GoogleMapControl"), myOptions); alert(gMap.getBounds()); So now it alerts me that gMap.getBounds() is undefined. I've tryed to get getBounds values in click event and it works fine for me, but I cannot get the same results in load map event. Also getBounds works fine while document is loading in Google Maps API v2, but it fails in V3. Could you please help me to solve this problem?

  • How to calculate short & long distance via Haversine?

    - by Jeroen
    Hi, I am looking for a way to calculate the distance between 2 points on the globe. We've been told to use Haversine, which works fine to calculate the shortest distance between the 2 points. Now, I'd like to calculate the "long distance" between to points. So suppose you have 2 cities, A in the west and B in the east. I want to know the distance from B to A if I would travel eastwards around the globe and then reach A coming from the west. I've tried changing a couple of things in the haversine function, but doesn't seem to work. Anyone know how I can simply do this using small adjustments to the haversine function? This is what I'm using now: lat1, lat2, lng1, lng2 are in radians part1 = sin(lat2) * sin(lat1); part2 = cos(lat2) * cos(lat1) * cos(lng1 - lng2); distance = EARTH_RADIUS * acos(part1 + part2); Tnx Jeroen

  • Handling exception from unmanaged dll in C#

    - by StuffHappens
    Hello. I have the following function written in C# public static string GetNominativeDeclension(string surnameNamePatronimic) { if(surnameNamePatronimic == null) throw new ArgumentNullException("surnameNamePatronimic"); IntPtr[] ptrs = null; try { ptrs = StringsToIntPtrArray(surnameNamePatronimic); int resultLen = MaxResultBufSize; int err = decGetNominativePadeg(ptrs[0], ptrs[1], ref resultLen); ThrowException(err); return IntPtrToString(ptrs, resultLen); } catch { return surnameNamePatronimic; } finally { FreeIntPtr(ptrs); } } Function decGetNominativePadeg is in unmanaged dll [DllImport("Padeg.dll", EntryPoint = "GetNominativePadeg")] private static extern Int32 decGetNominativePadeg(IntPtr surnameNamePatronimic, IntPtr result, ref Int32 resultLength); and throws an exception: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. The catch that is in C# code doesn't actually catch it. Why? How to handle this exception? Thank you for your help!

  • Which functions in the C standard library commonly encourage bad practice?

    - by Ninefingers
    Hello all, This is inspired by this question and the comments on one particular answer in that I learnt that strncpy is not a very safe string handling function in C and that it pads zeros, until it reaches n, something I was unaware of. Specifically, to quote R.. strncpy does not null-terminate, and does null-pad the whole remainder of the destination buffer, which is a huge waste of time. You can work around the former by adding your own null padding, but not the latter. It was never intended for use as a "safe string handling" function, but for working with fixed-size fields in Unix directory tables and database files. snprintf(dest, n, "%s", src) is the only correct "safe strcpy" in standard C, but it's likely to be a lot slower. By the way, truncation in itself can be a major bug and in some cases might lead to privilege elevation or DoS, so throwing "safe" string functions that truncate their output at a problem is not a way to make it "safe" or "secure". Instead, you should ensure that the destination buffer is the right size and simply use strcpy (or better yet, memcpy if you already know the source string length). And from Jonathan Leffler Note that strncat() is even more confusing in its interface than strncpy() - what exactly is that length argument, again? It isn't what you'd expect based on what you supply strncpy() etc - so it is more error prone even than strncpy(). For copying strings around, I'm increasingly of the opinion that there is a strong argument that you only need memmove() because you always know all the sizes ahead of time and make sure there's enough space ahead of time. Use memmove() in preference to any of strcpy(), strcat(), strncpy(), strncat(), memcpy(). So, I'm clearly a little rusty on the C standard library. Therefore, I'd like to pose the question: What C standard library functions are used inappropriately/in ways that may cause/lead to security problems/code defects/inefficiencies? In the interests of objectivity, I have a number of criteria for an answer: Please, if you can, cite design reasons behind the function in question i.e. its intended purpose. Please highlight the misuse to which the code is currently put. Please state why that misuse may lead towards a problem. I know that should be obvious but it prevents soft answers. Please avoid: Debates over naming conventions of functions (except where this unequivocably causes confusion). "I prefer x over y" - preference is ok, we all have them but I'm interested in actual unexpected side effects and how to guard against them. As this is likely to be considered subjective and has no definite answer I'm flagging for community wiki straight away. I am also working as per C99.

  • click events issue in jquery.

    - by alex
    I don't know if the title explain this situation well. Below is a code i wrote to create div elements when the button is pressed. Then By clicking on any of the created divs, we can change the div background by choosing a color from the drop down box. However if i click on another div and tried to change the color by selecting another color from the drop down, the previously clicked divs also gets affected by the new color. Why is this happening. I only want the selected div to change color, without affecting the previously clicked divs. I read allot of threads on this site, some of which talks about unbinding clicks, but I'm unable to solve the problem. Thanks for the help. <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script> <style> .aaa { width:100px; height:100px;background-color:#ccc;margin-bottom:5px;} p{widht:500px; height:500px; margin:0px; padding:0px;border:2px solid red;color:#000;} </style> <select id="item_select" name="item"> <option value="1">red</option> <option value="2">blue</option> <option value="3">green</option> </select> <button>Click to create divs</button> <p id="ptest"></p> <script type="text/javascript"> var dividcount = 1; $("button").click(run); function run(){ var myDiv = $('<div id=lar'+dividcount+' class=aaa></div>'); $(myDiv).clone().appendTo('#ptest'); $(dividcount++); $("div").bind('click',(function() { var box = $("div").index(this); var idd = (this.id); $("#"+idd).text("div #"+idd); $("select").change(function(){ var str= $("select option:selected").text(); $("#"+idd).css("background-color",str); }); })); }; </script>

  • JavaScript tree / treegrid libraries

    - by desau
    I'm looking for a good JavaScript tree / treegrid package. Now -- before you answer: It needs to be able to perform well with lots of nodes. Perhaps 1,000 sibling nodes. It needs to be able to draw to a usable state within 2 or 3 seconds with 1,000 nodes. It doesn't necessarily need to draw all 1,000 nodes at once -- if it supports some sort of "smart rendering" or fake scrolling. Beyond that, column resizing, drag and drop, inline editing would all be nice, although I could probably add that functionality myself. I've already tried dojo's tree and yahoo's YUI treeview. Both are too slow.

  • Python- Convert a mixed number to a float

    - by user345660
    I want to make a function that converts mixed numbers and fractions (as strings) to floats. Here's some examples: '1 1/2' -> 1.5 '11/2' -> 5.5 '7/8' -> 0.875 '3' -> 3 '7.7' -> 7.7 I'm currently using this function, but I think it could be improved. It also doesn't handle numbers that are already in decimal representation def mixedtofloat(txt): mixednum = re.compile("(\\d+) (\\d+)\\/(\\d+)",re.IGNORECASE|re.DOTALL) fraction = re.compile("(\\d+)\\/(\\d+)",re.IGNORECASE|re.DOTALL) integer = re.compile("(\\d+)",re.IGNORECASE|re.DOTALL) m = mixednum.search(txt) n = fraction.search(txt) o = integer.search(txt) if m: return float(m.group(1))+(float(m.group(2))/float(m.group(3))) elif n: return float(n.group(1))/float(n.group(2)) elif o: return float(o.group(1)) else: return txt Thanks!

  • jQuery(document).ready doesn't run under IIS7

    - by gsiler
    To simplify this test case, I created a new default .NET MVC project in Visual Studio 2010, and added the following code to the HTML header in Site.Master: <script type="text/javascript" src="../../Scripts/jquery-1.4.1.js"></script> <script type="text/javascript"> jQuery(document).ready(function () { alert('jQuery document ready'); }); </script> This works as expected in the .NET development server. However, when deployed to IIS7, the jQuery(document).ready function is not executed. Needless to say, my actual application is much more complicated. This eliminates all "suspects" except IIS7 deployment. Any thoughts/suggestions?

  • django - dynamic form fieldsets

    - by user110029
    A form will be spitting out an unknown number of questions to be answered. each question contains a prompt, a value field, and a unit field. The form is built at runtime in the formclass's init method. I'd like each question rendered on the form as an inline: prompt, value(input-text), units (select). this seems a case perfect for iterable form fieldsets, which could be easily styled. but since fieldsets - such as those in django-form-utils are defined as tuples, they are immutable... and I can't find a way to define them at runtime. is this possible, or perhaps another solution?

  • SignalR cross domain does not work after updating to 0.5.1

    - by jlp
    My site uses SignalR to communicate cross-domain. It worked great but I updated SignalR from 0.5.0 to 0.5.1 and my site broke. Here's my script: function start() { $.connection.hub.url = "http://otherdomain.com/signalr"; $.connection.hub.start().done(function () { $.connection.myHub.join(); }); } When script calls join - I see in Firebug that it is a POST (I believe it shoold be GET (jsonp) since it is cross domain) with no response. EDIT: I tried $.connection.hub.start({jsonp: true}). Now I have can call server from client but calls from server don't execute on client. I noticed that there are following calls: negotiate and send whereas locally (the same domain) there are: negotiate, connect, send.

  • Javacript in html - Using single quote inside another single quote

    - by Ashish Nair
    document.getElementById("img").innerHTML="< img src='/sitepath/"+imgg+".jpg' width='72' height='44' onclick='alert('hello');' />"; The above code is my javascript. Problem is printing hello or any other string. If I just type 123 in place of hello, it does give alert. But am not able to use a string like hello there. Normally a string in an alert function is kept inside quotes ' ' but the entire content is inside double quotes and I have already used single quote at the beginning of onclick function. I tried using Escape character ("\") but it didnt help. Any suggestions?

  • jquery set focus on dynamic content?

    - by Alan
    In jquery I've appended a <li> element to an unordered list. How do I focus on the newly created <li> ? If I do the following: $("ul").append('<li><input type="text">hi!</input></li>'); $("li:last").focus(); //doesn't work because new <li> isn't in dom yet the focus doesn't work, as noted above. I know jquery 1.4.2 has a live() event handler which allows you load event handlers to dynamically added elements, but I'm not sure what I'm doing wrong: $(document).ready(function () { $('li').live('load', function () { alert("hi!"); $("li:last").focus(); }); });

  • Can't disable jQuery cache

    - by robert_d
    Update I figured out that it must be caching problem but I can't turn cache off. Here is my changed script: <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery.ajaxSetup({ // Disable caching of AJAX responses cache: false }); jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 3000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> It updates part of a web page every 3 sec. It works only once after clearing web browser cache, after that it doesn't work - requests are made to /Home/Refresh without interval of 3 seconds and nothing is displayed on the web page; subsequent requests send cookie ASP.NET_SessionId=wrkx1avgvzwozcn1frsrb2yh. I am using ASP.NET MVC 2 and c#. I have a problem with jQuery, here is how my web app works Search.aspx web page which contains a form and jQuery script posts data to Search() action in Home controller after user clicks button1 button. Search.aspx: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Title </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Search</h2> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <div class="editor-label"> <%: Html.LabelFor(model => model.Url) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Url, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Url) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Location) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Location, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Location) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.KeywordLines) %> </div> <div class="editor-field"> <%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%> <%: Html.ValidationMessageFor(model => model.KeywordLines)%> </div> <p> <input id ="button1" type="submit" value="Search" /> </p> </fieldset> <% } %> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 5000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> <div id="divResult"> </div> </asp:Content> [HttpPost] public ActionResult Search(WebGLSQuery queryToCreate) { if (!ModelState.IsValid) return View("Search"); queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"]; Session["Result"] = null; SearchKeywordLines(queryToCreate); Thread.Sleep(15000); return View("Search"); }//Search() After button1 button is clicked the above script from Search.aspx web page runs. Search() action in controller runs for longer period of time. I simulate this in testing by putting Thread.Sleep(15000); in Search()action. 5 sec. after Submit button was pressed, the above jQuery script calls Refresh() action in Home controller. public ActionResult Refresh() { ViewData["Result"] = DateTime.Now; return PartialView(); } Refresh() renders this partial <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" % <%= ViewData["Result"] % The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh; in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds. I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work. I would be grateful for helpful suggestions.

  • Variable in one query is getting into another query in view

    - by Jason Shultz
    I have two foreach statements. The variable from one one is somehow getting into another and i'm not sure how to fix it. Here's my controller: // Categories Page Code function categories($id) { $this->load->model('Business_model'); $data['businessList'] = $this->Business_model->categoryPageList($id); $data['catList'] = $this->Business_model->categoryList(); $data['featured'] = $this->Business_model->frontPageList(); $data['user_id'] = $this->tank_auth->get_user_id(); $data['username'] = $this->tank_auth->get_username(); $data['page_title'] = 'Welcome To Jerome - Largest Ghost Town in America'; $data['page'] = 'category_view'; // pass the actual view to use as a parameter $this->load->view('container',$data); } What happens is categories will only show the businesses in a certain category. The businesses are pulled from the database using the categoryPageList($id) function. Here is that function: function categoryPageList($id) { $this->db->select('b.id, b.busname, b.busowner, b.webaddress, p.thumb, v.title, c.catname, s.specname, p.thumb, c.id'); $this->db->from ('business AS b'); $this->db->where('b.category', $id); $this->db->join('photos AS p', 'p.busid = b.id', 'left'); $this->db->join('video AS v', 'v.busid = b.id', 'left'); $this->db->join('specials AS s', 's.busid = b.id', 'left'); $this->db->join('category As c', 'b.category = c.id', 'left'); $this->db->group_by("b.id"); return $this->db->get(); } And here is the view: <h2>Welcome to Jerome, Arizona</h2> <p>Choose the Category of Business you are interested in:<br/> <?php foreach ($catList->result() as $row): ?> <a href="/site/categories/<?=$row->id?>"><?=$row->catname?></a>, &nbsp; <?php endforeach; ?></p> <table id="businessTable" class="tablesorter"> <thead><tr><th>Business Name</th><th>Business Owner</th><th>Web</th><th>Photos</th><th>Videos</th><th>Specials</th></tr></thead> <?php if(count($businessList) > 0) : foreach ($businessList->result() as $crow): ?> <tr> <td><a href="/site/business/<?=$crow->id?>"><?=$crow->busname?></a></td> <td><?=$crow->busowner?></td> <td><a href="<?=$crow->webaddress?>">Visit Site</a></td> <td> <?php if(isset($crow->thumb)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->title)):?> yes <?php else:?> no <?php endif?> </td> <td> <?php if(isset($crow->specname)):?> yes <?php else:?> no <?php endif?> </td> </tr> <?php endforeach; ?> <?php else : ?> <td colspan="4"><p>No Category Selected</p></td> <?php endif; ?> </table> The problem occurs here. <?=$crow->id?> should be showing the row id from the business table. Instead, it's showing the row ID of the category table. so, if i'm viewing /site/categories/6 <?=$crow->id?> will show 6 when it should be showing 10 (the row ID of the only business in that category at this time. How can I fix this?

  • "Randomly" occurring errors...

    - by ClarkeyBoy
    Hi, My website has a setup whereby when the application starts a module called SiteContent is "created". This runs a clearup function which basically deletes any irrelevant data from the database, in case any has been left in there from previously run functions. The module has instances of Manager classes - namely RangeManager, CollectionManager, DesignManager. There are others but I will just use these as an example. Each Manager class contains an array of items - items may be of type Range, Collection or Design, whichever one is relevant. Data for each range is then read into an instance of Range, Collection or Design. I know this is basically duplicating data - not very efficient but its my final year project at the moment so I can always change it to use Linq or something similar later, when I am not pressured by the one month deadline. I have a form which, on clicking the Save button, saves data by calling SiteContent.RangeManager.Create(vars) or SiteContent.RangeManager.Update(Range As Range, vars) (or the equivalent for other manager classes, whichever one happens to be relevant). These functions call a stored procedure to insert or update in the relevant table. Classes Range, Collection and Design all have attributes such as Name, Description, Display and several others. When the Create or Update function is called, the Manager loops through all the other items to check if an item with the same name already exists. The Update function ensures that it does not compare the item being updated to itself. A custom exception (ItemAlreadyExistsException) is thrown if another item with the same name is found. For some weird reason, if I go into a Range, Collection or Design in edit mode, change something and try to update it, it occasionally doesnt update the item. When I say occasionally I mean every 3 - 4 page loads, sometimes more. I see absolutely no pattern in when or why it occurs. I have a try-catch statement which catches ItemAlreadyExistsException, and outputs "An item with this name already exists" when caught. Occasionally it will output this; other times it will not. Does anyone have any idea why this could happen? Maybe a mistake which someone has made and solved before? I used to have regular expressions in place that the names were compared to - I believe it was [a-zA-Z]{1, 100} (between 1 and 100 lower- or upper-case characters). For some reason the customer who I am developing the site for used to get errors saying its not in the correct format. Yet he could try the same text 5 minutes later and it would work fine. I am thinking this could well be the same problem, since both problems occur at random. Many thanks in advance. Regards, Richard Clarke Edit: After much time spent narrowing down the code, I have decided to wait till my brother, who has been a programmer for at least 8 years more than I have, to come down over Easter and get him to have a look at it. If he cant solve it then I will zip the files up and put them somewhere for people to access and have a go at. I narrowed it down literally to the minimum number of files possible, and it still occurs. It seems to be about every 10th time. Having said that, I force the manager classes to refresh every 10 page loads or 5 minutes (whichever one is sooner). I may look into this - this could be causing a problem. Basically each Manager contains an array of an object. This array is populated using data from the database. The Update function takes an instance of the item and the new values to be set for the object. If it happens to be a page load where the array is reset (ie the data is loaded freshly from the database) then the object instance with the same ID wont be the same instance as the one being passed in. This explains the fact that it throws an ItemAlreadyExistsException now and then. It all makes sense now the more I think about it. If I were to pass in the ID of the object to be altered, rather than the object itself, then it should work perfectly. I will answer the question if I solve it..

  • passing json from servlet to dojo

    - by Moev4
    I am currently trying to pass a generated JSON string to dojo for parsing and am having some issues. The servlet simply writes it as a string as so: response.getWriter().append("{ \"data\": {"); response.getWriter().append("\"type\": \"facing\","); response.getWriter().append("\"score\": " + "\"" + score + "\","); response.getWriter().append("\"count\":" + "\"" + count + "\"" ); response.getWriter().append("}}"); which prints as: {"data":{"type":"facing","score":"10","count":"24"}} And the parsing on the dojo end looks as so: dojo.xhrPost({ url: url, handleAs: "json", load: function(data) { alert(data); /* Parse Not working */ alert(data.data[0].type); }, error: function(error) { alert("No dice") } }); The main issue is the data.data[0].type is returning nothing but when i print this out as text the json seems to be correctly formatted. Any help with this would be appreciated.

  • Interface member name conflicts in ActionScript 3

    - by Aaron
    I am trying to create an ActionScript 3 class that implements two interfaces. The interfaces contain member functions with different signatures but the same name: public interface IFoo { function doStuff(input:int):void; } public interface IBar { function doStuff(input1:String, input2:Number):void; } public class FooBar implements IFoo, IBar { // ??? } In C# this problem can be solved with explicit interface implementations, but as far as I can tell ActionScript does not have that feature. Is there any way to create a class that implements both interfaces?

  • How does this ajax call persist DOM changes in the browser cache?

    - by Greg
    For the purpose of the question I need to create a simple fictitious scenario. I have the following trivial page with one link, call it page A: <a class="red-anchor" onclick="change_color(event);" href="http://mysite.com/b/">B</a> With the associated Javascript function: function change_color(e) { var event = e || window.event; var link = event.target; link.className = "green-anchor"; } And I have the appropriate CSS to make the anchor red or green based on the classname. This is working. That is, when I click the anchor it changes color from red to green, which is briefly visible before the browser loads page B. But if I then use the BACK button to return to page A I get different behavior in different browsers. In Safari, the anchor is still green (desired behavior) In Firefox it reverts to red I imagine that Safari is somehow updating its cached version of the page, whereas Firefox isn't. So my first question is: is there any way to get FF to update the cached page, or is something else happening here? Secondly: I have a different implementation where I use an ajax call. In this I set the class of the anchor using a session variable, something like... <a class="<?php echo $_SESSION["color"]; ?>" ...[snip]... >B</a> And the javascript function makes an additional ajax call that changes the "color" session variable. In this case both Safari and Firefox work as expected. When going back from B to A the color is still green. But I can't for the life of me figure out why it should be different to the non-ajax case. I have tried many different permutations and for it to work on FF the "color" session variable MUST change (i.e. the ajax call itself is not somehow reloading the cache). But on coming BACK, the page is being reloaded from the cache (verified in Firebug), so how is the page even accessing this session variable if it isn't reprocessing the page and running that fragment of php in the anchor? I figure there must be something fundamental here that I am not understanding. Any insight would be much appreciated.

  • Exception using SQLiteDataReader

    - by galford13x
    I'm making a Custom SQLite Wrapper. This is meant to allow a presistent connection to a database. However, I receive an exception when calling this function twice. public Boolean DatabaseConnected(string databasePath) { bool exists = false; if (ConnectionOpen()) { this.Command.CommandText = string.Format(DATABASE_QUERY); using (reader = this.Command.ExecuteReader()) { while (reader.Read()) { if (string.Compare(reader[FILE_NAME_COL_HEADER].ToString(), databasePath, true) == 0) { exists = true; break; } } reader.Close(); } } return exists; } I use the above function to check if the database is currently open before executing a command or trying to open a database. The first time I execute the function, it executes with no issue. After that the reader = this.Command.ExecuteReader() throws an exception Object reference not set to an instance of an object.
