  • Using C# regex to select text based on custom tags

    - by spaceman
    I have a string in c# containing some data i need to extract based on certain conditions. The string contains many tenders in the following form : <TENDER> some words, don't know how many, may contain numbers and things like slashes (/) or whatever <DESCRIPTION> some more words and possibly other things like numbers or whatever describing the tender here </DESCRIPTION> some more words and possibly numbers and weird things </TENDER> This string doesn't contain any nested <TENDER> tags, its flat. The <DESCRIPTION> tags occur only once within the <TENDER> tags. I'm using : <TENDER>(.+?)</TENDER> as the regex to split up the tenders and it works fine. If this is wrong or stupid and you know a better way to write this please let me know as I have discovered I suck at regex. My problem that I now need to only select a tender if its description contains any word in a list of keywords (lets say for now i want to select a tender only if it contains either "concrete" or"brick" in the description). So far the regex I have come up with looks like this, but I don't know what to put in the middle. Also I have a vague suspicion that this might return me some false positives. <TENDER>(.+?)<DESCRIPTION>have no idea what to do here</DESCRIPTION>(.+?)</TENDER> If any of you regex guru's could point me in the right direction I would be most appreciative.

  • How to dispose a Writeable Bitmap? (WPF)

    - by Mario
    Some time ago i posted a question related to a WriteableBitmap memory leak, and though I received wonderful tips related to the problem, I still think there is a serious bug / (mistake made by me) / (Confusion) / (some other thing) here. So, here is my problem again: Suppose we have a WPF application with an Image and a button. The image's source is a really big bitmap (3600 * 4800 px), when it's shown at runtime the applicaton consumes ~90 MB. Now suppose i wish to instantiate a WriteableBitmap from the source of the image (the really big Image), when this happens the applications consumes ~220 MB. Now comes the tricky part, when the modifications to the image (through the WriteableBitmap) end, and all the references to the WriteableBitmap (at least those that I'm aware of) are destroyed (at the end of a method or by setting them to null) the memory used by the writeableBitmap should be freed and the application consumption should return to ~90 MB. The problem is that sometimes it returns, sometimes it does not. Here is a sample code: // The Image's source whas set previous to this event private void buttonTest_Click(object sender, RoutedEventArgs e) { if (image.Source != null) { WriteableBitmap bitmap = new WriteableBitmap((BitmapSource)image.Source); bitmap.Lock(); bitmap.Unlock(); //image.Source = null; bitmap = null; } } As you can see the reference is local and the memory should be released at the end of the method (Or when the Garbage collector decides to do so). However, the app could consume ~224 MB until the end of the universe. Any help would be great.

  • WCF net.tcp bindings, message formats and security questions

    - by RemotecUk
    Hi, sorry for the stupid questions but there are just some things about WCF I cant get my head around. Would be greatful for some advice on the following.... At a very basic level is it correct that WCF uses either Binary (Net.Tcp), HTTP or MSMQ to transfer my message on the wire? However is it true that in all cases, regardless of how the data is transferred the message itself in in the SOAP format with headers and a body? So its a sort of XML message that is transmitted in either HTTP/S or in a binary format. Is Net.Tcp a good choice for my client server app - its similar to a messenger app in that the clients are all remote users on the other side of the firewall to my server. Most things I am reading are telling to use WS* and HTTP. Is Net.Tcp secured by standard and without certificates? - that is - people cannot listen on the wire and decode the data thats going to and from. Is it possible to send a username and password using net.tcp and without an installed certificate? If so I presume I can hook this up to my membership provider and authenticate access to each method on my service contract implementation. I presume that with username and password security, the proxy is initialised with the username and password and that this information is is sent with every request. Then my membership provider will be invoked for each method call and do whatever it needs to do to get the authorisation for the method. Sorry for the dump of questions but would be great to know if Im thinking the right way about how WCF works. Thanks.

  • empty response body in ajax (or 206 Partial Content)

    - by Nikita Rybak
    Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

  • Fix common library functions, or abandon then?

    - by Ian Boyd
    Imagine i have a function with a bug in it: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } So the call: MakeLocation("Springfield", "MO"); would return "Springfield, MO" Now there's a slight problem, what if the user called: MakeLocation("Springfield, MO", "OH"); The called it wrong, obviously. But the function would return "Springfield, MO, OH". The system was functioning like this for many years, until i noticed the function being used wrong, and i corrected it. And i also updated the original function to catch such an obvious mistake - in case it's happening elsewhere: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } And testing showed the problem fixed. Except we missed an edge case, and the customer found it. So now the moral dillema. Do you ever add new sanity checks, safety checks, assertions to exising code? Or do you call the old function abandoned, and have a new one: Boolean MakeLocation(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" return City+", "+State; } Boolean MakeLocation2(String City, String State) { //Given "Springfield", "MO" //return "Springfield, MO" if (City.Contains, ",") throw new EMakeLocationException("City name contains a comma. You probably didn't mean that"); return City+", "+State; } The same can apply for anything: Question FetchQuestion(Int id) { if (id == 0) throw new EFetchQuestionException("No question ID specified"); ... } Do you risk breaking existing code, at the expense of existing code being wrong?

  • Friend Assemblies in C#

    - by Tim Long
    I'm trying to create some 'friend assemblies' using the [InternalsVisibleTo()] attribute, but I can't seem to get it working. I've followed Microsoft's instructions for creating signed friend assemblies and I can't see where I'm going wrong. So I'll detail my steps here and hopefully someone can spot my deliberate mistake...? Create a strong name key and extract the public key, thus: sn -k StrongNameKey sn -p public.pk sn -tp public.pk Add the strong name key to each project and enable signing. Create a project called Internals and a class with an internal property: namespace Internals { internal class ClassWithInternals { internal string Message { get; set; } public ClassWithInternals(string m) { Message = m; } } } Create another project called TestInternalsVisibleTo: namespace TestInternalsVisibleTo { static class Program { /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main() { var c = new Internals.ClassWithInternals("Test"); Console.WriteLine(c.Message); } } } Edit the AssemblyInfo.cs file for the Internals project, and add teh necessary attribute: [assembly: AssemblyTitle("AssemblyWithInternals")] [assembly: AssemblyDescription("")] [assembly: AssemblyConfiguration("")] [assembly: AssemblyCompany("Microsoft")] [assembly: AssemblyProduct("Internals")] [assembly: AssemblyCopyright("Copyright © Microsoft 2010")] [assembly: AssemblyTrademark("")] [assembly: AssemblyCulture("")] [assembly: ComVisible(false)] [assembly: Guid("41c590dc-f555-48bc-8a94-10c0e7adfd9b")] [assembly: AssemblyVersion("1.0.0.0")] [assembly: AssemblyFileVersion("1.0.0.0")] [assembly: InternalsVisibleTo("TestInternalsVisibleTo PublicKey=002400000480000094000000060200000024000052534131000400000100010087953126637ab27cb375fa917c35b23502c2994bb860cc2582d39912b73740d6b56912c169e4a702bedb471a859a33acbc8b79e1f103667e5075ad17dffda58988ceaf764613bd56fc8f909f43a1b177172bc4143c96cf987274873626abb650550977dcad1bb9bfa255056bb8d0a2ec5d35d6f8cb0a6065ec0639550c2334b9")] And finally... build! I get the following errors: error CS0122: 'Internals.ClassWithInternals' is inaccessible due to its protection level error CS1729: 'Internals.ClassWithInternals' does not contain a constructor that takes 1 arguments error CS1061: 'Internals.ClassWithInternals' does not contain a definition for 'Message' and no extension method 'Message' accepting a first argument of type 'Internals.ClassWithInternals' could be found (are you missing a using directive or an assembly reference?) Basically, it's as if I had not used the InternalsVisibleTo attrbute. Now, I'm not going to fall into the trap of blaming the tools, so what's up here? Anyone?

  • set iPhone Required device capabilities

    - by chozinul
    My application is for "iPhone ONLY", But I have made a mistake in the first place by not setting the application for specific device. The current setting now is: Requirement: Compatible for iPhone, iPod touch and iPad. I would like to set it to: Requirement: Compatible for iPhone. I have go to some tutorial and forum. and nothing can solve my problem. I have also contact the apple support and this is what I got: "You are permitted to expand your device requirements only. Submitting an update to your binary to restrict your device requirements is not permitted. " is it mean that I can not set my application for iPhone only? If i can change it, what would you recommend me to do? I have change the setting of device capability inside the plist, to one of this. which one is correct, use "UIRequiredDeviceCapabilities" or "Required device capabilities"? i provide the screenshoot in here: http://img218.imageshack.us/gal.php?g=screenshot20100604atam1.png does the way I use it correct?

  • C# Check if character exists in encoding

    - by Alvin Wong
    I am writing a program that a part renders a bitmap font in CP437. In a function that renders the text with I want to be able to check whether a char is available in CP437 before the encoding conversion, like: public static void DrawCharacter(this Graphics g, char c) { if (char_exist_in_encoding(Encoding.GetEncoding(437), c) { byte[] src = Encoding.Unicode.GetBytes(c.ToString()); byte[] dest = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(437), src); DrawCharacter(g, dest[0]); // Call the void(this Graphics, byte) overload } } Without the check, any characters outside CP437 will result in a '?' (63, 0x3F). I want to hide any invalid characters completely. Is there an implementation of char_exist_in_encoding other than the following stupid approach? public static bool char_exist_in_encoding(Encoding e, char c) { if (c == '?') return true; byte[] src = Encoding.Unicode.GetBytes(c.ToString()); byte[] dest = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(437), src); if (dest[0] == 0x3F) return false; return true; } Perhaps not very relevant, but the bitmap is created like this: Bitmap b = new Bitmap(256 * 8, 16); Graphics g = Graphics.FromImage(b); g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixelGridFit; Font f = new Font("Whatever 8x16 bitmap font", 16, GraphicsUnit.Pixel); for (byte i = 0; i < 255; i++) { byte[] arr = Encoding.Convert(Encoding.GetEncoding(437), Encoding.Unicode, new byte[] { i }); char c = Encoding.Unicode.GetChars(arr)[0]; g.DrawString(c.ToString(), f, Brushes.Black, i * 8 - 3, 0); // Don't know why it needs a 3px offset } b.Save(@"D:\chars.png");

  • zend_form display group inside foreach

    - by Mike
    I want to create a display group generated from foreach() clause output. I can't seem to get the syntax correct. Here's the business logic: for each category row find the associated fees output the category description as a label and the fees as radio buttons then create a display group with the fees as the group elements and the category description as the legend. I then have a style sheet format the elements on the page. and here's the code: foreach ($categoryData as $categoryRow) { $fees[$i] = new Zend_Form_Element_Radio("fees[$i]"); $fees[$i]->setDescription(strval($categoryRow['description'])); foreach ($feeData as $feeRow) { if ($feeRow['categories_idCategory'] == $categoryRow['idCategory']){ $fees[$i] ->addMultiOption($feeRow['idFees'] . '-' . $feeRow['categories_idCategory'], $feeRow['amount'] . '-' . $feeRow['name']); } } $fees[$i]->setRequired(TRUE); $this->addElements(array($fees[$i])); $this->addDisplayGroup($feeRow['name'], 'feeGroup',array('legend' => strval($feeRow['description']))); $i++; } I tried placing the addDisplayGroup() code within the foreach(), but I get the error: Message: No valid elements specified for display group So, my guess is that I'm making some kind of novice mistake that you experts will spot right away. I appreciate your time and attention to this matter.

  • Implementing Naïve Bayes algorithm in Java - Need some guidance

    - by techventure
    hello stackflow people As a School assignment i'm required to implement Naïve Bayes algorithm which i am intending to do in Java. In trying to understand how its done, i've read the book "Data Mining - Practical Machine Learning Tools and Techniques" which has a section on this topic but am still unsure on some primary points that are blocking my progress. Since i'm seeking guidance not solution in here, i'll tell you guys what i thinking in my head, what i think is the correct approach and in return ask for correction/guidance which will very much be appreciated. please note that i am an absolute beginner on Naïve Bayes algorithm, Data mining and in general programming so you might see stupid comments/calculations below: The training data set i'm given has 4 attributes/features that are numeric and normalized(in range[0 1]) using Weka (no missing values)and one nominal class(yes/no) 1) The data coming from a csv file is numeric HENCE * Given the attributes are numeric i use PDF (probability density function) formula. + To calculate the PDF in java i first separate the attributes based on whether they're in class yes or class no and hold them into different array (array class yes and array class no) + Then calculate the mean(sum of the values in row / number of values in that row) and standard divination for each of the 4 attributes (columns) of each class + Now to find PDF of a given value(n) i do (n-mean)^2/(2*SD^2), + Then to find P( yes | E) and P( no | E) i multiply the PDF value of all 4 given attributes and compare which is larger, which indicates the class it belongs to In temrs of Java, i'm using ArrayList of ArrayList and Double to store the attribute values. lastly i'm unsure how to to get new data? Should i ask for input file (like csv) or command prompt and ask for 4 values? I'll stop here for now (do have more questions) but I'm worried this won't get any responses given how long its got. I will really appreciate for those that give their time reading my problems and comment.

  • Is MEF an all-or-nothing affair?

    - by Dave
    I've had a few questions about MEF recently, but here's the big one -- is it really all-or-nothing, as it appears to be? My basic application structure is simply an app, several shared libraries that are intended to be singletons, and several different plugins (which may implement different interfaces). The app loads the plugins, and both the app and all plugins need to access the shared libraries. My first go at MEF was fairly successful, although I made some stupid mistakes along the way because I was trying so many different things, I just got confused at times. But in the end, last night I got my smallish test app running with MEF, some shared libraries, and one plugin. Now I'm moving onto the target app, which I already described. And it's the multiple plugins part that has be a bit worried. My existing application already supports multiple plugins with different interfaces by using Reflection. I need to be able to uniquely identify each plugin so that the user can select one and get the expected behavior exposed by that plugin. The problem is that I don't know how to do this yet... but that's the topic of a different question. Ideally, I'd be able to take my existing plugin loader and use it as-is, while relying on MEF to do the shared library resolution. The problem is, I can't seem to get MEF to load them (i.e. I get a CompositionException when calling ComposeParts()) unless I also use MEF to load the plugin. And if I do this, well... then I need to know how to keep track of them as they get loaded so the user can select one from a list of plugins. What have your experiences been with trying to mix and match these approaches?

  • How to explain to users the advantages of dumb primary key?

    - by Hao
    Primary key attractiveness I have a boss(and also users) that wants primary key to be sophisticated/smart/attractive control number(sort of like Social Security number, or credit card number format) I just padded the primary key(in Views) with zeroes to appease their desire to make the control number sophisticated,smart and attractive. But they wanted it as: first 2 digits as client code, then 4 digits as year year, then last 4 digits as transaction number on that client on a given year, then reset the transaction number of client to 1 when next year flows. Each client's transaction starts with 1. e.g. WM20090001, WM20090002, BB2009001, WM20100001, BB20100001 But as I wanted to make things as simple as possible, I forgo embedding their suggested smartness in primary key, I just keep the primary key auto increments regardless of client and year. But to make it not dull-looking(they really are adamant to make the primary key as smart control number), I made the primary key appears to them smart, on view query, I put the client code and four digit year code on front of the eight-zero padded autoincrement key, i.e. WM200900000001. Sort of slug-like information on autoincremented primary key. Keeping primary key autoincrement regardless of any other information, we are able keep other potential side effects problem when they edit a record, for example, if they made a mistake of entering the transaction on WM, then they edit the client code to BB, if we use smart primary key, the primary keys of WM customer will have gaps in their control number. Or worse yet, instead of letting the control numbers have gaps/holes, the user will request that subsequent records of that gap should shift up to that gap and have their subsequent primary keys re-adjust(decremented). How do you deal with these user requests(reasonable or otherwise)? Do you yield to their request? Or just continue using dumb primary key and explain them the repercussions of having a very smart/sophisticated primary key and educate them the significant advantages of having a dumb primary key? P.S. quotable quote(http://articles.techrepublic.com.com/5100-10878_11-1044961.html): "If you hold your tongue the first time users ask what is for them a reasonable request, things will work a lot better in the end."

  • SSL certificates: No Client certificate key exhange

    - by user334246
    I am trying to access a WCF web service, that is using two way SSL encryption. When I try to call the service I get a System.ServiceModel.Security.SecurityNegotiationException: Could not establish secure channel for SSL/TLS with authority 'XXX.xx'. --- System.Net.WebException: The request was aborted: Could not create SSL/TLS secure channel. I have tried activating wire shark, to see what is sent to and from the server: I see a client hello and a server hello. But there is no client response to the server hello. I was expecting a "Certificate. Client key exchange. Change cipher. Encrypted handshake Message" package, but none is sent. I'm thinking it is a problem with the certificate sent by the server, that somehow my client server does not trusy it. Here is what I have already tried: I have created the certificate, through the proper authority, though I could have made a mistake in the certificate request without knowing it. I have added the two root certificates to: trusted root certificates, trusted publishers and trusted people. I have also added the client certificate to trusted people. My colleague has succeded in establishing connection on a win 2008 server (i'm using a 2003, because it is necessary for some odd reason - don't ask). I can't see any differences in our approach, so i'm a bit lost. Any help would be greatly appreciated.

  • Parse a xml attribute depending on child content

I want to load in the "url"-attribute from <user> , but only if <name> and <lastname> matches the name values i have stored in my own user database. I know how to parse the rest of it with PHP, but just the matching sequence seems difficult to me. Any help appreciated!

    Hi , I have a perl client which is calling a http restlet service (put method). Some of the parameters in this call contain japanese text. when I printed the contents of these request parameters in the restlet service I found these chars garbled ! This is my PERL client code: my %request_headers = ( 'DocumentName' => $document_name, --> This name is a JAPANESE String 'DocumentDescription' => 'Test Japanese Chars', 'content-length' => 200, 'Content-Type' => 'application/octet-stream; charset=utf-8', 'User-Agent' => "JPCharTester", ); $s-write_request('PUT', '/test-document/TEST/TEST_DOCUMENT' , %request_headers, $content); in this call both the values of $context and $document_name are JAPANESE Strings. But ONLY the document_name is received as garbled in my backend service. Here goes the Service code: String URL_ENCODING = "UTF-8"; String documentName = requestHeaders.getFirstValue("DocumentName"); System.out.println("Encoded Document Name : "+documentName+" <<<"); --> documentName is garbled here try { documentName = URLDecoder.decode(documentName, URL_ENCODING); System.out.println(>>> Decoded Document Name : "+documentName+" <<<"); --> documentName is garbled here } catch (java.io.UnsupportedEncodingException ex) { throwException(ex.getMessage(), Status.SERVER_ERROR_INTERNAL, ex); } both the above log statements printed GARBLED TEXT !! Can someone tell me what is the mistake I am doing and how to fix this ? Thanks in advance for your help. Regards, Satish.

  • NSXMLParser: how do I wait until loading has finished?

    - by Archagon
    Let's say I'm using NSXMLParser to load a level (stored as an XML document, obviously) into my iPhone game. NSXMLParser works by assigning a delegate and sending it messages at key moments. How do I ensure that my entire level is loaded before doing anything else? I know I can make my main class the delegate and implement parserDidEndDocument, but this feels very hacky. My main class shouldn't have to know anything about the way the parsing is done! On the other hand, if I make a separate class/delegate for parsing my level, my main class has no way of knowing when the parsing is finished, unless it queries the parsing class continuously or the parsing class sends it a message. Either way, the main class would be tied to the implementation of the parsing class. Can I hide all this event-driven business from the main class and simply make the parser return the level object when it's done? (i.e., newLevel = [[GameLevel alloc] initFromXML:xmlfile], which would in turn use NSXMLParser to load the level and then somehow return when finished.) At the moment, I'm using an external DOM parser, but I'm curious how this would be done with NSXMLParser. Sorry if this is a stupid question -- I'm a bit new to this!

  • Usage of ||, OR in PHP

    - by shin
    I have the following code which redirect pages depends on $path. ... $path = $this->uri->segment(3); $pathid = $this->uri->segment(4); if($path=='forsiden'){ redirect('','refresh'); }elseif($path =='contact'){ redirect('welcome/kontakt','refresh'); }elseif($path =='illustration'){ $this->_gallery($path,$pathid); }elseif($path =='webdesign'){ redirect('welcome/webdesign','refresh'); }elseif($path==('web_tjenester' || 'webdesigndetails' || 'vismahjemmeside' || 'joomla' || 'vismanettbutikk' || 'vpasp' || 'artportfolio')){ ... CODE A ... }else{ ... CODE B ... } I am not getting right results with $path==('web_tjenester' || 'webdesigndetails' || 'vismahjemmeside' || 'joomla' || 'vismanettbutikk' || 'vpasp' || 'artportfolio') contact, illustration, gallery and webdesign are redirected and working alright. However all other pages are added CODE A. I am expecting CODE A only when $path is web_tjenester', 'webdesigndetails', 'vismahjemmeside', 'joomla', 'vismanettbutikk', 'vpasp' or 'artportfolio'. Could anyone point out my mistake and correct me please? Thanks in advance. --UPDATE-- The following works, but is there any ways shorten the code? I am repeating ($path==..). elseif(($path=='web_tjenester') || ($path=='webdesigndetails') || ($path=='vismahjemmeside') || ($path=='joomla') || ($path=='vismanettbutikk') || ($path=='vpasp') || ($path=='artportfolio')){

  • WPF designer gives exception when databinding a label to a checkbox

    - by John
    I'm sure it's something stupid, but I'm playing around with databinding. I have a checkbox and a label on a form. What I'm trying to do is simply bind the Content of the label to the checkbox's IsChecked value. What I've done runs fine (no compilation errors and acts as expected), but if I touch the label in the XAML, the designer trows an exception: System.NullReferenceException Object reference not set to an instance of an object. at MS.Internal.Designer.PropertyEditing.Editors.MarkupExtensionInlineEditorControl.BuildBindingString(Boolean modeSupported, PropertyEntry propertyEntry) at <Window x:Class="UnitTestHelper.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:FileSysCtls="clr-namespace:WPFFileSystemUserControls;assembly=WPFFileSystemUserControls" xmlns:HelperClasses="clr-namespace:UnitTestHelper" Title="MainWindow" Height="406" Width="531"> <Window.Resources> <HelperClasses:ThreestateToBinary x:Key="CheckConverter" /> </Window.Resources> <Grid Height="367" Width="509"> <CheckBox Content="Step into subfolders" Height="16" HorizontalAlignment="Left" Margin="17,254,0,0" Name="chkSubfolders" VerticalAlignment="Top" Width="130" IsThreeState="False" /> <Label Height="28" HorizontalAlignment="Left" Margin="376,254,0,0" Name="lblStepResult" VerticalAlignment="Top" Width="120" IsEnabled="True" Content="{Binding IsChecked, ElementName=chkSubfolders, Mode=OneWay, UpdateSourceTrigger=PropertyChanged, Converter={StaticResource CheckConverter}}" /> </Grid> The ThreeStateToBinary class is as follows: class ThreestateToBinary : IValueConverter { #region IValueConverter Members public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { if ((bool)value) return "Checked"; else return "Not checked"; //throw new NotImplementedException(); } public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture) { return ((string)value == "Checked"); //throw new NotImplementedException(); } #endregion } Quite honestly, I'm playing around with it at this point. It was originally simpler (not using the ValueConverter) but was displaying similar behavior when I simply had the content set to: Content="{Binding IsChecked, ElementName=chkSubfolders, UpdateSourceTrigger=PropertyChanged}" Any ideas? Thanks, John

  • SQL 2000 (MSDE) Hangs When It Receives an Erroneous Query from a Classic ASP Web Application

    - by Jimbo
    I have a SQL interface page in my classic ASP web app that allows admin users to run queries against the app's database (MSDE 2000) - it simply consists of a textarea that the user submits and the app returns the resulting list of records as below Dim oRS Set oRS = Server.CreateObject("ADODB.Recordset") oRS.ActiveConnection = sConnectionString // run the query - this is for the admin only so doesnt check for sql safe commands etc. oRS.Open Request.Form("txtSQL") If Not oRS.EOF Then // list the field names from the recordset For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).name & "&nbsp;" Next // show the data for each record in the recordset While Not oRS.EOF For i = 0 to oRS.Fields.Count - 1 Response.Write oRS.Fields(i).value & "&nbsp;" Next Response.Write "<br />" oRS.Movenext() Wend End If The problem with this is that if you send it an invalid query (with a spelling mistake, invalid join etc.) instead of throwing back an error immediately, it hangs IIS (you can see this by trying to browse the app from another computer, it fails) for a number of minutes and THEN returns the error. I have NO idea why! Can anyone help?

  • extjs - 'Store is undefined'

    - by Jamie
    Hi all, I'm pretty sure this a trivial problem and i'm just being a bit stupid. Your help would be hugely appreciated. In controls/dashboard.js I have: Ext.ill.WCSS.controls.dashboard = { xtype:'portal', region:'center', margins:'35 5 5 0', items:[{ columnWidth: 1, style:'padding:10px', items:[{ title: 'My Cluster Jobs', layout:'fit', html: "test" }] },{ columnWidth: 1, style:'padding:10px', items:[{ title: 'All Cluster Jobs', iconCls: 'icon-queue', html: "test", items: new Ext.grid.GridPanel({ title: 'Cluster Job Queue', store: Ext.ill.WCSS.stores.dashboardClusterJobs, width: 791, height: 333, frame: true, loadMask: true, stateful: false, autoHeight: true, stripeRows: true, floating: false, footer: false, collapsible: false, animCollapse: false, titleCollapse: false, columns:[ { xtype: 'gridcolumn', header: 'Job ID', sortable: true, resizable: true, width: 100, dataIndex: 'JB_job_number', fixed: false }, { xtype: 'gridcolumn', header: 'Priority', sortable: true, resizable: true, width: 100, dataIndex: 'JAT_prio', fixed: false }, { xtype: 'gridcolumn', header: 'User', sortable: true, resizable: true, width: 100, dataIndex: 'JB_owner' }, { xtype: 'gridcolumn', header: 'State', sortable: true, resizable: true, width: 100, dataIndex: 'state' }, { xtype: 'gridcolumn', header: 'Date Submitted', sortable: true, resizable: true, width: 100, dataIndex: 'JAT_start_time' }, { xtype: 'gridcolumn', header: 'Queue', sortable: true, resizable: true, width: 100, dataIndex: 'queue_name' }, { xtype: 'gridcolumn', header: 'CPUs', sortable: true, resizable: true, width: 100, dataIndex: 'slots' } ], bbar: { xtype: 'paging', store: 'storeClusterQueue', displayInfo: true, refreshText: 'Retrieving queue status...', emptyMsg: 'No jobs to retrieve', id: 'clusterQueuePaging' } }) }] }] }; Simple enough, note the reference to 'Ext.ill.WCSS.stores.dashboardClusterJobs' So in stores/dashboard.js I just have this: Ext.ill.WCSS.stores.dashboardClusterJobs = new Ext.data.XmlStore({ storeId: 'storeClusterJobs', record: 'job_list', autoLoad: true, url: 'joblist.xml', idPath: 'job_info', remoteSort: false, fields: [ { name: 'JB_job_number' }, { name: 'JAT_prio' }, { name: 'JB_name' }, { name: 'JB_owner' }, { name: 'state' }, { name: 'JAT_start_time' }, { name: 'slots' }, { name: 'queue_name' } ] }); I run the code and I get 'store is undefined' :S It's confusing me a lot. All of the javascripts have been included in the correct order. i.e. <script type="text/javascript" src="/js/portal.js"></script> <script type="text/javascript" src="/js/stores/dashboard.js"></script> <script type="text/javascript" src="/js/controls/dashboard.js"></script> Thanks guys!

  • Give WPF design mode default objects

    - by Janko R
    In my application I have <Rectangle.Margin> <MultiBinding Converter="{StaticResource XYPosToThicknessConverter}"> <Binding Path="XPos"/> <Binding Path="YPos"/> </MultiBinding> </Rectangle.Margin> The Data Context is set during runtime. The application works, but the design window in VS does not show a preview but System.InvalidCastException. That’s why I added a default object in the XYPosToThicknessConverter which is ugly. class XYPosToThicknessConverter : IMultiValueConverter { public object Convert(object[] values, Type targetType, object parameter, System.Globalization.CultureInfo culture) { // stupid check to give the design window its default object. if (!(values[0] is IConvertible)) return new System.Windows.Thickness(3, 3, 0, 0); // useful code and exception throwing starts here // ... } } My Questions: What does VS/the process that builds the design window pass to XYPosToThicknessConverter and what is way to find it out by myself. How do I change my XAML code, so that the design window gets its default object and is this the best way to handle this problem? I’m using VS2010RC with Net4.0

  • Adding & Removing Dynamic Controls in C# WinForms.

    - by gsvirdi
    I have three Tabs in my WinForm; depending on the selected RaioButton in the TabPages[0] I added few dynamic controls on the relevant TabPage. On Button_Click event the controls are added, but the prob is the I'm not able to remove the Dynamically added controls from the other (irrelevant) TabPage. Here's my code: Label label235 = new Label(); TextBox tbMax = new TextBox(); label235.Name = "label235"; tbMax.Name = "txtBoxNoiseMax"; label235.Text = "Noise"; tbMax.ReadOnly = true; label235.ForeColor = System.Drawing.Color.Blue; tbMax.BackColor = System.Drawing.Color.White; label235.Size = new Size(74, 13); tbMax.Size = new Size(85, 20); if (radioButton1.Checked) { label235.Location = new Point(8, 476); tbMax.Location = new Point(138, 473); tabControl.TabPages[1].Controls.Add(label235); tabControl.TabPages[1].Controls.Add(tbMax); tabControl.TabPages[2].Controls.RemoveByKey("label235"); tabControl.TabPages[2].Controls.RemoveByKey("tbMax"); } else { label235.Location = new Point(8, 538); tbMax.Location = new Point(138, 535); tabControl.TabPages[1].Controls.RemoveByKey("label235"); tabControl.TabPages[1].Controls.RemoveByKey("tbMax"); tabControl.TabPages[2].Controls.Add(label235); tabControl.TabPages[2].Controls.Add(tbMax); } Where am I making that mistake?????
