  • Unable to attach "AdventureWorks2008" Sample Database to a named Instance in SQL Server 2008

    - by uzorick
    First of all "Northwind" and "AdventureWorksDW2008" databases attached without problem, but "AdventureWorks2008" fails with the following error. // Msg 5120, Level 16, State 105, Line 1 Unable to open the physical file "C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\Documents".

  • c# Named Pipe Asynchronous Peeking

    - by KJ Tsanaktsidis
    Hey all, I need to find a way to be notified when a System.IO.Pipe.NamedPipeServerStream opened in asynchronous mode has more data available for reading on it- a WaitHandle would be ideal. I cannot simply use BeginRead() to obtain such a handle because it's possible that i might be signaled by another thread which wants to write to the pipe- so I have to release the lock on the pipe and wait for the write to be complete, and NamedPipeServerStream doesnt have a CancelAsync method. I also tried calling BeginRead(), then calling the win32 function CancelIO on the pipe if the thread gets signaled, but I don't think this is an ideal solution because if CancelIO is called just as data is arriving and being processed, it will be dropped- I still wish to keep this data, but process it at a later time, after the write. I suspect the win32 function PeekNamedPipe might be useful but i'd like to avoid having to continuously poll for new data with it. In the likley event that the above text is a bit unclear, here's roughly what i'd like to be able to do... NamedPipeServerStream pipe; ManualResetEvent WriteFlag; //initialise pipe lock (pipe) { //I wish this method existed WaitHandle NewDataHandle = pipe.GetDataAvailableWaithandle(); Waithandle[] BreakConditions = new Waithandle[2]; BreakConditions[0] = NewDataHandle; BreakConditions[1] = WriteFlag; int breakcode = WaitHandle.WaitAny(BreakConditions); switch (breakcode) { case 0: //do a read on the pipe break; case 1: //break so that we release the lock on the pipe break; } }

  • Reloading an external element (via jQuery's .load) without impact on same-named host elements on sam

    - by Martin Pescador
    Hello together! [First, I'm an absolute beginner. I tried to express myself as good as I could - please correct me on any issue... Now: I have the following problem:] I am loading a div element, which class always is ".gallery" from a couple of pages (in this example "the page index.php?page=orange") into another page's div (in this case with the ID "orange") using the following code: $("#orange").load("http://example.com/index.php?page=orange .gallery"); Each div.gallery I load in, is a set of a few images. Between them, you can switch (there are "previous"- and "next"-links in ".imgnavi"). $(".imgnavi a").live("click", function(ev) { ev.preventDefault(); ev.stopPropagation(); $(".gallery").load($(this).attr("href")); return false; }) What happens now: Loading the different div.gallery into the new page is no problem, but as soon as I start to navigate inside those divs (each div is a little gallery, where you can switch between images), the div.gallery I am switching in is suddenly loaded into EVERY other div.gallery in the document! How do I prevent that?

  • the scope of a pointer ???

    - by numerical25
    Ok, so I did find some questions that were almost similar but they actually confused me even more about pointers. http://stackoverflow.com/questions/2715198/c-pointer-objects-vs-non-pointer-objects-closed In the link above, they say that if you declare a pointer it is actually saved on the heap and not on the stack, regardless of where it was declared at. Is this true ?? Or am I misunderstanding ??? I thought that regardless of a pointer or non pointer, if its a global variable, it lives as long as the application. If its a local variable or declared within a loop or function, its life is only as long as the code within it.

  • Cannot see named Silverlight control in code

    - by Alexandra
    In my first few hours with Silverlight 3, as an avid WPF user, I am greatly disappointed at the many things it doesn't support. This seems like an odd issue to me and it's so generic that I cannot find anything online about it. I have the following XAML: <controls:TabControl x:Name="workspacesTabControl" Grid.Row="1" Background="AntiqueWhite" ItemsSource="{Binding Workspaces, ElementName=_root}"/> However, I cannot see the workspacesTabControl in code-behind. I thought maybe IntelliSense is just being mean and tried to go ahead and compile it anyway, but got an error: Error 1 The name 'workspacesTabControl' does not exist in the current context How do I access controls in code-behind? EDIT: I realized I've pasted the wrong error - I have two controls inside the UserControl called workspacesTabControl and menuStrip. I cannot get to either one of them by their name in the code-behind. Just in case, here is the XAML for the menuStrip: <controls:TreeView Grid.ColumnSpan="2" Height="100" x:Name="menuStrip" ItemContainerStyle="{StaticResource MenuStripStyle}" ItemsSource="{Binding Menu, ElementName=_root}"/> EDIT AGAIN: I'm not sure if this is helpful, but I've taken a look at the InitializeComponent() code and here's what I saw: [System.Diagnostics.DebuggerNonUserCodeAttribute()] public void InitializeComponent() { if (_contentLoaded) { return; } _contentLoaded = true; System.Windows.Application.LoadComponent(this, new System.Uri("/SapphireApplication;component/SapphireMain.xaml", System.UriKind.Relative)); } It seems that it simply loads the XAML when it runs (not before or during compilation) so the menuStrip and workspacesTabControl names don't actually get registered anywhere (as they usually are in WPF/win Forms). Could that attribute be a problem? And where do I get rid of this requirement for all the future UserControls I make?

  • Call named routes in CakePHP as the same way in Ruby on Rails

    - by Lucas Renan
    How can I call a route (in the view) in CakePHP as the same way in Rails? Ruby on Rails routes.rb map.my_route '/my-route', :controller => 'my_controller', :action => 'index' view link_to 'My Route Name', my_route_path CakePHP routes.php Router::connect('/my-route', array('controller' => 'my_controller', 'action' => 'index')); view $html->link('My Route Name', '/my-route'); But I think the Rails way is better, because I can make changes in the "url" and I don't need changes the code of the views.

  • Scope of Connection Object for a Website using Connection Pooling (Local or Instance)

    - by Danny
    For a web application with connection polling enabled, is it better to work with a locally scoped connection object or instance scoped connection object. I know there is probably not a big performance improvement between the two (because of the pooling) but would you say that one follows a better pattern than the other. Thanks ;) public class MyServlet extends HttpServlet { DataSource ds; public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } void SomeWork(String sql) { Connection conn = null; try { conn = ds.getConnection(); // execute some sql ..... } finally { if(conn != null) { conn.close(); // return to pool } } } } Or public class MyServlet extends HttpServlet { DataSource ds; Connection conn;* public void init() throws ServletException { ds = (DataSource) getServletContext().getAttribute("DBCPool"); } protected void doGet(HttpServletRequest arg0, HttpServletResponse arg1) throws ServletException, IOException { try { conn = ds.getConnection(); SomeWork("SELECT * FROM A"); SomeWork("SELECT * FROM B"); } finally { if(conn != null) { conn.close(); // return to pool } } } void SomeWork(String sql) { // execute some sql ..... } }

  • HTMLAgilityPack ChildNodes index works, named node does not

    - by XgenX
    I am parsing an XML API response with HTMLAgilityPack. I am able to select the result items from the API call. Then I loop through the items and want to write the ChildNodes to a table. When I select ChildNodes by saying something like: sItemId = dnItem.ChildNodes(0).innertext I get the proper itemId result. But when I try: sItemId = dnItem.ChildNodes("itemId").innertext I get "Referenced object has a value of 'Nothing'." I have tried "itemID[1]", "/itemId[1]" and a veriety of strings. I have tried SelectSingleNode and ChildNodes.Item("itemId").innertext. The only one that has worked is using the index. The problem with using the index is that sometimes child elements are omitted in the results and that throw off the index. Anybody know what I am doing wrong?

  • String formatting named parameters?

    - by Mark
    I know it's a really simple question, but I have no idea how to google it. how can I do print '<a href="%s">%s</a>' % (my_url) So that my_url is used twice? I assume I have to "name" the %s and then use a dict in the params, but I'm not sure of the proper syntax? just FYI, I'm aware I can just use my_url twice in the params, but that's not the point :)

  • Can I modify package.xml file in SQL bootstrapper to install a named SQL server instance

    - by jonmiddleton
    I want to use the SqlExpress2008 Bootstrapper for a new installation on Windows7, I do not want to use the default SQLEXPRESS Instance. I have attempted to edit the package.xml file located in: C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\SqlExpress2008\en\package.xml and updated the command argument instancename=CUSTOMINSTANCE But unfortunately it still creates the default SQLEXPRESS not CUSTOMINSTANCE The wix tag is as follows: <sql:SqlDatabase Id="SqlDatabaseCore" ConfirmOverwrite="yes" ContinueOnError="no" CreateOnInstall="yes" CreateOnReinstall="no" CreateOnUninstall="no" Database="MyDatabase" DropOnInstall="no" DropOnReinstall="no" DropOnUninstall="no" Instance="[SQLINSTANCE]" Server="[SQLSERVER]"> <sql:SqlFileSpec Id="SqlFileSpecCore" Filename="[CommonAppDataFolder]MyCompany\Database\MyDatabase.mdf" Name="MyDatabase" /> <sql:SqlLogFileSpec Id="SqlLogFileSpecCore" Filename="[CommonAppDataFolder]MyCompany\Database\MyDatabase.ldf" Name="MyDatabaseLog" /> Is this the standard way to accomplish this?

  • named groups splitting regardless of position of match

    - by jeremy
    Having a hard time explaining what I mean, so here is what I want to do I want any sentenced to be parsed along the pattern of text #something a few words [someothertext] for this, the matching sentence would be Jeremy is trying #20 times to [understand this] And I would name 4 groups, as text, time, who, subtitle However, I could also write #20 Jeremy is trying [understand this] times to and still get the tokens #20 Jeremy is trying times to understand this corresponding to the right groups As long as the delimited tokens can separate the 2 text only tokens, I'm fine. Is this even possible? I've tried a few regex's and failed miserably (am still experimenting but finding myself spending way too much time learning it)

  • What is the scope of xsl apply-imports?

    - by calavera.info
    My original idea about apply-imports was that if there are two templates which matches the same node, then using apply-imports in a template with higher priority runs the template with the lower priority. But I recently find out that it's important how are imports organized. Two cases interests me particularly. Will apply imports work on a template which is imported in imported file (nested import)? How about a "sibling import" (master file imports two files with templates matching the same nodes) It seems to me that this is not clearly described in specification. Could someone provide authoritative guidelines? EDIT: I can try those cases on my own, but there is always a danger that it will be implementation specific behavior.

  • jQuery form wizard - named anchor links

    - by Jackson
    Hi Team, Using: http://home.aland.net/sundman/ to split a complex form in to 4 steps. As well as as the 'next, back and submit' form buttons, I have created a menu above the form: step 1, step 2, step 3, step 4 linking to the hash tags #: #, #1, #2, #3 so the visitor can decide which step they want to view / edit. This works fine in firefox, but in IE and Chrome it does not seem to work. Anyone have experience with hte jQuery history plugin that can tell me the best way to accomplish this? I would like to link to the form but it is in a password protected area and subject to our NDA. If need be I could try and replicate the issue with a form on our server and link here. Thanks, Jack

  • Named Function Expressions in IE, part 2

    - by Polshgiant
    I asked this question a while back and was happy with the accepted answer. I just now realized, however, that the following technique: var testaroo = 0; (function executeOnLoad() { if (testaroo++ < 5) { setTimeout(executeOnLoad, 25); return; } alert(testaroo); // alerts "6" })(); returns the result I expect. If T.J.Crowder's answer from my first question is correct, then shouldn't this technique not work?

  • C stack/scope, variable's lifetime after functions ends

    - by Ranking Stackingblocks
    void someFunc() { int stackInt = 4; someOtherFunc(&stackInt); } Is it the case that stackInt's address space could be reallocated after someFunc ends, making it unsafe to assume that the value passed to someOtherFunc represents the stackInt variable with value 4 that was passed to it? In other words, should I avoid passing stack variables around by address and expecting them to still be alive after the function they were initialised in has ended?

  • Visual Studio expression containing a term named "by" cannot be evaluated in the watch window

    - by Andrei Pana
    Consider my C++ code below: int _tmain(int argc, _TCHAR* argv[]) { int by = 10; printf("%d\n", by); int bx = 20; printf("%d\n", (by + bx)); return 0; } which works fine. The funny thing is with the "by" variable. If I try to add a watch for a simple expression that contains by, the result will be CXX0030: Error: expression cannot be evaluated. For example, on a breakpoint on return 0, if I add the following watches I get the results mentioned: by : 10 bx : 20 by + 5 : CXX0030: Error: expression cannot be evaluated bx + 5 : 25 by + bx : CXX0030: Error: expression cannot be evaluated (by) + bx : 30 by + (bx) : CXX0030: Error: expression cannot be evaluated bx + (by) : CXX0014: Error: missing operrand This happens on VS2010, VS2008 on multiple computers. So, more out of curiosity, what is happening with "by"? Is it some kind of strange operator? Why doesn't bx get the same treatment? (I've tried google on this but it is quite difficult to get some relevant hits with terms like "by")

  • Javascript Array Scope - newbie here

    - by Gianluca
    So, I am learning Javascript while playing white Google Calendar APIs and I just can't figure how this piece of code is working this way: var entriesResult = []; var data = new Date(2010,3,22,17,0,0); var callback = function(result) { var entries = result.feed.getEntries(); if (entries.length != 0) { entriesResult = eventsManager(entries, 0, data); window.alert("inner entriesResult " + entriesResult.length); } } this.service.getEventsFeed(this.query, callback, handleGDError); window.alert("outer entriesResult " + entriesResult.length); eventsManager() is a function that returns an array of Objects. getEventsFeed() it's an API function: it queries the service and pass a "feed root" (a feed with selected items) to the callback function. Why the first alert (inner..) outputs a valid entriesResult.length while the second one (outer..) always outputs a 0? I tought javascript arrays are always passed by reference, what's wrong whit my code? Thank you :)

  • What are 'len', 'dir', 'vars' named?

    - by johannix
    I was wondering what language to use when talking about a function that takes in a specific object, acts on it and returns something else. Clearly they're functions, but I was wondering if there's a more specific term. A couple examples of Python built-in functions that fit this spec are: 'len', 'dir', 'vars' I thought it was 'predicate', but apparently that's specific to functions that return a boolean value.

  • TWiki: Restricting users scope of editing the pages.

    I am making a twiki website and I am stuck with a problem. The users have access to write the files. So, I want to include Report Abuse option so that in case of vandalism of someone the thing can be corrected as soon as possible. Also, I am facing one more problem that someone told me that while editing the code the person can change the read/write permissions for the other users. And obviously, that wouldn't be something that I am expecting from Twiki. C'mon there must be some way of moderation in twiki to ensure thatthere is no undesirable content.

Each time the function is called to store a value, it should allocate the next cell of the A column to store that object.
