    - by Ahmed
    For a panel with one textbox and one button which is its default button, the DefaultButton event fires only once as editing textbox details again and pressing enter, event doesn't fire. <asp:Panel runat="server" ID="pnlNewFolderDetails" DefaultButton="btnAddFolder"> <asp:Label runat="server" ID="lblFolderHeader" Text="New Folder Name" CssClass="label" /> <asp:TextBox runat="server" ID="txtFolderName" ToolTip="Folder Name" /> <asp:Button runat="server" ID="btnAddFolder" OnClick="btnAddFolder_Click" Text="Add" /> Any suggestions?

  • Skip List vs. Binary Tree

    - by Claudiu
    I recently came across the data structure known as a Skip list. They seem to have very similar behavior to a binary search tree... my question is - why would you ever want to use a skip list over a binary search tree?

  • MySQL: LIMIT then RAND rather than RAND then LIMIT

    - by Larry
    I'm using full text search to pull rows. I order the rows based on score (ORDER BY SCORE) , then of the top 20 rows (LIMIT 20), I want to rand (RAND) the result set. So for any specific search term, I want to randomly show 5 of the top 20 results. My workaround is code based- where I put the top 20 into an array then randomly select 5. Is there sql way to do this?

  • Java, server client TCP communication ends with RST

    - by Senne
    I'm trying to figure out if this is normal. Because without errors, a connection should be terminated by: FIN -> <- ACK <- FIN ACK -> I get this at the end of a TCP connection (over SSL, but i also get it with non-encrypted): From To 1494 server client TCP search-agent > 59185 [PSH, ACK] Seq=25974 Ack=49460 Win=63784 Len=50 1495 client server TCP 59185 > search-agent [ACK] Seq=49460 Ack=26024 Win=63565 Len=0 1496 client server TCP 59185 > search-agent [PSH, ACK] Seq=49460 Ack=26024 Win=63565 Len=23 1497 client server TCP 59185 > search-agent [FIN, ACK] Seq=49483 Ack=26024 Win=63565 Len=0 1498 server client TCP search-agent > 59185 [PSH, ACK] Seq=26024 Ack=49484 Win=63784 Len=23 1499 client server TCP 59185 > search-agent [RST, ACK] Seq=49484 Ack=26047 Win=0 Len=0 The client exits normally and reaches socket.close, shouldn't then the connection be shut down normally, without a reset?

  • API to toggle "Show hidden files, folders and drives"

    - by dbkk
    Is there a function in Windows API to toggle the "Show hidden files, folders and drives" option in Windows Explorer (Tools Folder Options... View tab). I know of a related registry key, but changing that would not have immediate effect. The key is: HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/Advanced/Folder/Hidden/SHOWALL Trying to do this from C#, but the question is not language-specific.

  • SharpZip escape filename

    - by mr.moses
    I'm using SharpZipLib to create a zip file with an html page and images. If the html file has a / in the name, it creates a folder (which messes up the image paths). Example: If the html file should be named Web/Design.html the zip file will contain a Web folder with a Design.html file in it. I've tried escaping / by replacing / with // or \/ but nothing has worked so far.

Im trying to create a new ASP.NET website and add it to my subversion repository but it does not work because subversion only add the C:\Users\XXX\Documents\Visual Studio 2008\Projects\WebApplication1 folder and ignores the project files located in C:\Users\XXX\Documents\Visual Studio 2008\WebSites folder. Why can't I add a ASP.NET website to Subversion like WindowsFormsApplications? How shall i add a ASP.NET website to Subversion repository?

  • C# Putting the required DLLs somewhere other than the root of the output

    - by aip.cd.aish
    I am using EmguCV for a project and when our program runs it needs some dlls like "cxcore.dll" etc. (or it throws runtime exceptions). At the moment, I put the files in the root of the output folder (selected "Copy Always" in the file's properties in Visual Studio). However it looks a bit messy, to have about 10 different dlls just there. Is there someway where I can move it to a subfolder in the output folder and it'll still find it.

  • Artificial Inteligence library in python

    - by João Portela
    I was wondering if there are any python AI libraries similar to aima-python but for a more recent version of python... and how they are in comparison to aima-python. I was particularly interested in search algorithms such as hill-climbing, simulated annealing, tabu search and genetic algorithms. edit: made the question more clear.

  • Data denormalization and C# objects DB serialization

    - by Robert Koritnik
    I'm using a DB table with various different entities. This means that I can't have an arbitrary number of fields in it to save all kinds of different entities. I want instead save just the most important fields (dates, reference IDs - kind of foreign key to various other tables, most important text fields etc.) and an additional text field where I'd like to store more complete object data. the most obvious solution would be to use XML strings and store those. The second most obvious choice would be JSON, that usually shorter and probably also faster to serialize/deserialize... And is probably also faster. But is it really? My objects also wouldn't need to be strictly serializable, because JsonSerializer is usually able to serialize anything. Even anonymous objects, that may as well be used here. What would be the most optimal solution to solve this problem? Additional info My DB is highly normalised and I'm using Entity Framework, but for the purpose of having external super-fast fulltext search functionality I'm sacrificing a bit DB denormalisation. Just for the info I'm using SphinxSE on top of MySql. Sphinx would return row IDs that I would use to fast query my index optimised conglomerate table to get most important data from it much much faster than querying multiple tables all over my DB. My table would have columns like: RowID (auto increment) EntityID (of the actual entity - but not directly related because this would have to point to different tables) EntityType (so I would be able to get the actual entity if needed) DateAdded (record timestamp when it's been added into this table) Title Metadata (serialized data related to particular entity type) This table would be indexed with SPHINX indexer. When I would search for data using this indexer I would provide a series of EntityIDs and a limit date. Indexer would have to return a very limited paged amount of RowIDs ordered by DateAdded (descending). I would then just join these RowIDs to my table and get relevant results. So this won't actually be full text search but a filtering search. Getting RowIDs would be very fast this way and getting results back from the table would be much faster than comparing EntityIDs and DateAdded comparisons even though they would be properly indexed.

  • Problem with the way the Ajax Control Toolkit TabContainer sets the default submit button

    - by Colin
    We have an Ajax Control Toolkit TabContainer containing some textboxes for doing a search. When you keypress inside one of the textboxes, the TabContainer sets the default button to be the button immediately following the tab control. This is fine because that's the search button. The problem occurs after the button is clicked and results returned. Now there is no default button, and keypress does nothing. Any suggestions?

  • How to “unbind” .result on Jquery Autocomplete?

    - by Cesar
    I have this code: $("#xyz").unautocomplete().autocomplete(dataVar, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }) .result(findValueCallback).next().click(function() { $(this).prev().search(); }); I call this code many times and the first call works correctly, but after he calls findValueCallback many times, not once more. The unautocomplete don't clear .result What I have to do for call findValueCallback once? Sample Code: var niveis01 = []; var niveis02 = []; var niveis03 = []; $(document).ready(function(){ carregaDadosNivel1(); }); function carregaDadosNivel1() { $.ajax({ url: "http://.....", cache: true, type: "POST", dataType:"json", success: function(data){ ... niveis01 = data; habilitaComboNivel1(); ... }, error: function(xhr, ajaxOptions, thrownError){ ... } }); } function habilitaComboNivel1() { function findValueCallback1(event, data01, formatted) { ... carregaDadosNivel2(); ... } $("#nivel01").unautocomplete().autocomplete(niveis01, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }).result(findValueCallback1).next().click(function() { $(this).prev().search(); }); } function carregaDadosNivel2() { $.ajax({ url: "http://.....", cache: true, type: "POST", dataType:"json", success: function(data){ ... niveis02 = data; habilitaComboNivel2(); ... }, error: function(xhr, ajaxOptions, thrownError){ ... } }); } function habilitaComboNivel2() { function findValueCallback2(event, data02, formatted) { ... carregaDadosNivel3(); ... } $("#nivel02").unautocomplete().autocomplete(niveis02, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }).result(findValueCallback2).next().click(function() { $(this).prev().search(); }); } function carregaDadosNivel3() { $.ajax({ url: ""http://.....", cache: true, type: "POST", dataType:"json", success: function(data){ ... niveis03 = data; habilitaComboNivel3(); ... }, error: function(xhr, ajaxOptions, thrownError){ ... } }); } function habilitaComboNivel3() { function findValueCallback3(event, data03, formatted) { ... } $("#nivel03").unautocomplete().autocomplete(niveis03, { minChars: 0, width: 400, matchContains: true, highlightItem: true, formatItem: formatItem, formatResult: formatResult }).result(findValueCallback3).next().click(function() { $(this).prev().search(); }); }

  • What are all the instances of syntactic sugar in Scala?

    - by Jackson Davis
    I decided to create this question to have a single source for all things syntactic sugar in Scala. I feel these details are some of the things most frustrating to starting users and are hard to search for since most/all of them are purely symbols and are thus hard to search for without knowing the name of the concept. TODO: implicit conversions _ syntax for anonymous functions Extractors(Unapply/UnapplySeq) Other things I'm forgetting
