  • jquery touch punch - draggable on ipad

    - by dshuta
    i am starting to work with the jquery touch punch extensions in order to allow draggability on ipad, but i am getting tripped up right away. probably something terribly dumb on my part. the draggable example from the developer works fine on my ipad: http://furf.com/exp/touch-punch/draggable.html but not for me: http://danshuta.com/touchpunch/ this works fine in my desktop browser, but on the ipad it just focuses on the block and scrolls the entire page as i drag, as if it were just an image or other normal embedded object. as this is what happens normally with jquery/ui on ipad, this makes me think it is not loading or otherwise ignoring the "punch" code from my site (though if i host the jquery files on my site via the same path, those load and function fine in desktop browser). here's the entire code, very basic: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Touchpunchtest</title> <script src="http://code.jquery.com/jquery.min.js"></script> <script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script> <script src="js/jquery.ui.touch-punch.js"></script> </head> <body> <div id="draggybox" onclick="void(0)" style="width: 150px; height: 150px; background: green;"></div> <script>$('#draggybox').draggable();</script> </body> </html> what am i missing?!

  • How to see external libraries code when debugging

    - by Sanva
    Hello!! First of all... this is my message #1 in this place, so... please be nice with me ;) I just started recently to study Gnome apps/libraries and I found that debuggers are an excellent way to learn, because seeing the code running helps a lot in understanding the structure of the program. But I have a problem. For example, debugging gnome-panel I found a lot of calls to external functions (basically the GTK+ functions), and although pretending to see all the code of all the functions applications like this call would be crazy, there are a lot that will be very interesting to see in action. The problem is that the debugger hasn't the code of those libraries loaded and it can't show it to me —at most it shows the line number where the execution is. I'm using Nemiver and when it tries to enter in an external function it claims because it can't find a file it supposed to be somewhere. For example, trying to enter in gtk_window_set_default_icon_name it tries to load /build/buildd/gtk+2.0-2.16.1/gtk/gtkwindow.c, and calling XSetIOErrorHandler, ../../src/ErrHndlr.c. So now I think that I'm doing something wrong... Why Nevimer are looking for those source files in those places?? My system does not even have the /build/buildd/ folders... and I don't know if I'm doing something wrong or I need to install somethig or what. Any suggestion? How do you debug this kind of applications? Best regards and thanks a lot for your time —and forgive me if my English is bad.

  • C++/CLI : Interop window is not properly configured

    - by raytaller
    Hi, I'm trying to load a WPF control in a C++/CLI application, using the HwndSource class. Here is my code : UBOOL MyWindowWrapper::Init(const HWND InParentWindowHandle) { Interop::HwndSourceParameters sourceParams( "WindowName" ); sourceParams.PositionX = 0; sourceParams.PositionY = 0; sourceParams.ParentWindow = (IntPtr)InParentWindowHandle; sourceParams.WindowStyle = (WS_VISIBLE | WS_CHILD); sourceParams.HwndSourceHook = nullptr; InteropWindow = gcnew Interop::HwndSource(sourceParams); Control = gcnew MyWPFUserControl(); InteropWindow-RootVisual = Control; InteropWindow-AddHook( gcnew Interop::HwndSourceHook( this, &MyWindowWrapper::MessageHookFunction ) ); return TRUE; } And I define a Hook function so the keyboard events are passed to the window : IntPtr MyWindowWrapper::MessageHookFunction( IntPtr HWnd, int Msg, IntPtr WParam, IntPtr LParam, bool% OutHandled ) { IntPtr Result = (IntPtr)0; OutHandled = false; if( Msg == WM_GETDLGCODE ) { OutHandled = true; // This tells Windows that we'll need keyboard events for this control Result = IntPtr( DLGC_WANTALLKEYS | DLGC_WANTCHARS | DLGC_WANTMESSAGE ); } return Result; } And here are my problems : The window title is empty (so the "WindowName" parameter is not taken in account) Only some keyboard events are transferred : space, control, arrows are ok, but I can't type any character in all the text boxes What am I doing wrong ? Thanks !

  • Why would the IE Developer Toolbar claim a style is applied, yet that supposed fact is not reflected

    - by Deane
    I have a situation where IE7 is simply not applying styles, even though it claims it is. I have an element on my page. In the CSS, I have defined a rule that should apply "display: none" to it, so it should not be displayed. It's still displaying. I downloaded the IE Developer Toolbar, and found the element in the DOM selector. I right-clicked and selected "Applied Styles." Right there, IE claims that it is applying my "display: none" rule. In fact, the "Applied Styles" dialog confirms everything I think I know about my CSS and how it should be applied. Yet the element remains. Now, I'm not asking anyone to debug my CSS here. I'm asking, if the IE Developer Toolbar claims/confirms this element should be gone, but it's still there...what does that mean, exactly? Since the Toolbar is on my side, I think my CSS is fine. Is there some IE7 bug I'm not considering? Edit: One thing that might be relevant: the LINK elements that load the stylesheets are applied to the page in Javascript, via "document.write". I'm starting to suspect that has something to do with it.

  • jQuery/JavaScript Date form validation

    - by Victor Jackson
    I am using the jQuery date picker calendar in a form. Once submitted the form passes params along via the url to a third party site. Everything works fine, except for one thing. If the value inserted into the date field by the datepicker calendar is subsequently deleted, or if the default date, that is in the form on page load, is deleted and the form is submitted I get the following error: "Conversion from string "" to type 'Date' is not valid." The solution to my problem is really simple, I want to validate the text field where the date is submitted and send out a default date (current date) if the field is empty for any reason. The problem is I am terrible at Javascript and cannot figure out how to do this. Here is the form code for my date field. [var('default_date' = date)] <input type="text" id="datepicker" name="txtdate" value="[$default_date]" onfocus="if (this.value == '[$default_date]') this.value = '';" onchange="form.BeginDate.value = this.value; form.EndDate.value = this.value;" /> <input type="hidden" name="BeginDate" value="[$default_date]"/> <input type="hidden" name="EndDate" value="[$default_date]"/>

  • Embed URL from variable in HTML file in Rails application

    - by TejasM

  • Problem importing Oracle .dmp file

    - by BitFiddler
    So I have looked at all the suggested ways of importing .dmp files and non of them seem to answer this question: where does the data go once you import it? Context: I created a user like so: SQL> create user IMPORTER identified by "12345"; SQL> grant connect, unlimited tablespace, resource to IMPORTER; I then ran the 'imp' command as follows: C:\>imp system/password FROMUSER=OVIEDOE TOUSER=IMPORTER file=c:\database1.dmp Now there were 9 .dmp files, after each one it asked me for the next one and then I received the message "Import terminated successfully with warnings." The warning was: Warning: the objects were exported by OVIEDOE, not by you import done in WE8MSWIN1252 character set and AL16UTF16 NCHAR character set export client uses WE8ISO8859P1 character set (possible charset conversion) IMP-00046: using FILESIZE value from export file of 2147483648 Now it says it was terminated successfully so my assumption (I am new to oracle so this may be wrong) is that the data was loaded. However, when I use SQL developer to connect to the database and look under the 'tables' node under the IMPORTER user, there is nothing there. What is going on? Did the data load? If so, where can I find it?

  • AM I using DO WHILE NOT and EOF in VBscript Properly

    - by Derek Drummond
    This block of code is causing my page to fail to load. When I comment out the line `DO WHILE NOT Rs.EOF the page loads properly. SQL_Command_String = "SELECT * FROM Seminars WHERE [SeminarID] = 5 ORDER BY DESC" Rs = SQLConnection.Execute(SQL_Command_String) DO WHILE NOT Rs.EOF file1 = "./seminars/" & seminar_type & "/" & seminar_year & "/" & Rs("Date") & "-" & Rs("Year") & "_" & Rs("Last") & ".pdf" file2 = "./seminars/" & seminar_type & "/" & seminar_year & "/" & Rs("Date") & "-" & seminar_year & "_" & Rs("Last") & "(handouts).pdf" file3 = "./seminars/" & seminar_type & "/" & seminar_year & "/" & Rs("Date") & "-" & seminar_year & "_" & Rs("Last") & "_Flyer.pdf" Rs.MoveNext loop Is the SQL_Command_String an invalid SQL Command or is my reader not being used properly when I try to build that specific file path e.g. Rs("Date")? Is there an option where I could do something like: DO WHILE RS.hasNextLine

  • Multithreading A Function in VB.Net

    - by Ben
    I am trying to multi thread my application so as it is visible while it is executing the process, this is what I have so far: Private Sub SendPOST(ByVal URL As String) Try Dim DataBytes As Byte() = Encoding.ASCII.GetBytes("") Dim Request As HttpWebRequest = TryCast(WebRequest.Create(URL.Trim & "/webdav/"), HttpWebRequest) Request.Method = "POST" Request.ContentType = "application/x-www-form-urlencoded" Request.ContentLength = DataBytes.Length Request.Timeout = 1000 Request.ReadWriteTimeout = 1000 Dim PostData As Stream = Request.GetRequestStream() PostData.Write(DataBytes, 0, DataBytes.Length) Dim Response As WebResponse = Request.GetResponse() Dim ResponseStream As Stream = Response.GetResponseStream() Dim StreamReader As New IO.StreamReader(ResponseStream) Dim Text As String = StreamReader.ReadToEnd() PostData.Close() Catch ex As Exception If ex.ToString.Contains("401") Then TextBox2.Text = TextBox2.Text & URL & "/webdav/" & vbNewLine End If End Try End Sub Public Sub G0() Dim siteSplit() As String = TextBox1.Text.Split(vbNewLine) For i = 0 To siteSplit.Count - 1 Try If siteSplit(i).Contains("http://") Then SendPOST(siteSplit(i).Trim) Else SendPOST("http://" & siteSplit(i).Trim) End If Catch ex As Exception End Try Next End Sub Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim t As Thread t = New Thread(AddressOf Me.G0) t.Start() End Sub However, the 'G0' sub code is not being executed at all, and I need to multi thread the 'SendPOST' as that is what slows the application.

  • ASP.NET web form Routing issue via UNC Path

    - by Slash
    I create a IIS 7.0 website via UNC path to load .aspx to dynamic compile files and runs. however, it's running perfect. I always use IIS URL Rewrite module 2 to rewrite my site URL n' its perfect, too. Today, I wanna use System.Web.Routing to implement url rewrite but I encountered difficulties... When I wrote code in Global.asax: System.Web.Routing.RouteTable.Routes.MapPageRoute("TEST", "AAA/{prop}", "~/BBB/CCC.aspx"); And it just CANNOT reDirect to /BBB/CCC.aspx When I type the URL(like: xx.xx.xx.xx/BBB/CCC.aspx) in browser directly, it runs normally that I want. (so it proof CCC.aspx is in right path.) thus, I copy all of the code and open VS2010 running with IIS 7.5 Express locally, it works perfect! e.g: in browser URL I type xx.xx.xx.xx/AAA/1234, it will turn to page xx.xx.xx.xx/BBB/CCC.aspx (Works perfect!) Why??? help me plz. thanks. Update: I think I should consider not UNC path to make it error! when I move all code to physical disk and setup IIS 7.0 to monitor this Folder, it still not works! But the same code run in VS2010 + IIS 7.5 Express it works!? so strange!

  • What database strategy to choose for a large web application

    - by Snoopy
    I have to rewrite a large database application, running on 32 servers. The hardware is up to date, each machine has two quad core Xeon and 32 GByte RAM. The database is multi-tenant, each customer has his own file, around 5 to 10 GByte each. I run around 50 databases on this hardware. The app is open to the web, so I have no control on the load. There are no really complex queries, so SQL is not required if there is a better solution. The databases get updated via FTP every day at midnight. The database is read-only. C# is my favourite language and I want to use ASP.NET MVC. I thought about the following options: Use two big SQL servers running SQL Server 2012 to serve the 32 servers with data. On the 32 servers running IIS hosting providing REST services. Denormalize the database and use Redis on each webserver. Use booksleeve as a Redis client. Use a combination of SQL Server and Redis Use SQL Server 2012 together with Hadoop Use Hadoop without SQL Server What is the best way for a read-only database, to get the best performance without loosing maintainability? Does Map-Reduce make sense at all in such a scenario? The reason for the rewrite is, the old app written in C++ with ISAM technology is too slow, the interfaces are old fashioned and not nice to use from an website, especially when using ajax. The app uses a relational datamodel with many tables, but it is possible to write one accerlerator table where all queries can be performed on, and all other information from the other tables are possible by a simple key lookup.

  • Easyslider content loading sooner than I would like.

    - by Jason
    I am using a jquery easyslider on a page and also pulling some rss feeds using php. Pulling the feeds is taking a long time and as a result delaying the load of the easy slider until after the feeds have been pulled in. This can be seen here: http://perksconsulting.com/dev/ I am looking for a way to display a loader image in the space where the easy slider is so the images do not appear stacked vertically for a few seconds while the php is interpreted by the server, but I have never used a loader image and am not sure how I would do that. I am currently using this script to hide the page contents until everything is loaded, but the one thing it is not hiding is the images from the easy slider: <SCRIPT TYPE="text/javascript" LANGUAGE="javascript"> function waitPreloadPage() { //DOM if (document.getElementById){ document.getElementById('prepage').style.visibility='hidden'; }else{ if (document.layers){ //NS4 document.prepage.visibility = 'hidden'; } else { //IE4 document.all.prepage.style.visibility = 'hidden'; } } } // End --> </SCRIPT> Ideally I would like to be able to display a loading image in place of the slider in the middle of the page until everything loads. Could anyone tell me how to do this? Thank you.

  • LINQ - Querying a list filtered via a Many-to-Many reltionship

    - by user118190
    Please excuse the context of my question for I did not know how to exactly word it. To not complicate things further, here's my business requirement: "bring me back all the Employees where they belong in Department "X". So when I view this, it will display all of the Employees that belong to this Department. Here's my environment: Silverlight 3 with Entity Framework 1.0 and WCF Data Services 1.0. I am able to load and bind all kinds of lists (simple), no problem. I don't feel that my environment matters and that's why I feel it is a LINQ question more than the technologies. My question is for scenarios where I have 3 tables linked, i.e. entities (collections). For example, I have this in my EDM: Employee--EmployeeProject--Project. Here's the table design from the Database: Employee (table1) ------------- EmployeeID (PK) FirstName other Attributes ... EmployeeProject (table2) ------------- EmployeeProjectID (PK) EmployeeID (FK) ProjectID (FK) AssignedDate other Attributes ... Project (table3) ------------- ProjectID (PK) Name other Attributes ... Here's the EDM design from Entity Framework: ------------------------ Employee (entity1) ------------------------ (Scalar Properties) ------------------- EmployeeID (PK) FirstName other Attributes ... ------------------- (Navigation Properties) ------------------- EmployeeProjects ------------------------ EmployeeProject (entity2) ------------------------ (Scalar Properties) ------------------- EmployeeProjectID (PK) AssignedDate other Attributes ... ------------------- (Navigation Properties) ------------------- Employee Project ------------------------ Project (entity3) ------------------------ (Scalar Properties) ------------------- ProjectID (PK) Name other Attributes ... ------------------- (Navigation Properties) ------------------- EmployeeProjects So far, I have only been able to do: var filteredList = Context.Employees .Where(e => e.EmployeeProjects.Where(ep => ep.Project.Name == "ProjectX")) NOTE: I have updated the syntax of the query after John's post. As you can see, I can only query, the related entity (EmployeeProjects). All I want is being able to filter to Project from the Employee entity. Thanks for any advice.

  • Is it possible to filter data used by pivot table based on filtering the rows in a source table in Excel?

    - by Geoffrey Stoel
    I have developed a dashboard in Excel 2007 that uses one source table in a sheet (being filled with a query on our data warehouse) and multiple pivot tables making different cross sections on this data. I use the GETPIVOTDATA in almost a hundred formulas to give me the right value for a specific indicator in my dashboard. This all works fine. However I now have received the question to make the dashboard for 5 different segments. As you can imagine I don't want to create 5 different workbooks for this and need to maintain the dashboard logic on all of them. So my question is the following. Is it possible to automatically (through VBA or any other means) filter the results in my source table which is the source for my pivot tables and thus for my dashboard values. So schematically: DATABASE_VIEW -- SOURCE_TABLE -- 12 pivot tables -- 100 GETPIVOTDATA functions Preferably I would like to load all the segments in the source_table (one view on my database) and then filter the data in the source table, which results in filterd source_dat for my pivots. This way I can (without requerying the db) quickly change between segments in the dashboards (refreshing pivots only). Data in the source table has the column: CUSTOMER_SEGMENT available to filter upon. Any help is appreciated. Geoffrey

  • Storing header and data sections in a CSV file

    - by morpheous
    This should be relatively easy to do, but after several hours straight programming my mind seems a bit frazzled and could do with some help. I have a C++ class which I am currently using to store read/write data to file. I was initially using binary data, but have decided to store the data as CSV in order to let programs written in other languages be able to load the data. The C++ class looks a bit like this: class BinaryData { public: BinaryData(); void serialize(std::ostream& output) const; void deserialize(std::istream& input); private: Header m_hdr; std::vector<Row> m_rows; }; I am simply rewriting the serialize/deserialize methods to write to a CSV file. I am not sure on the "best" way to store a header section and a "data" section in a "flat" CSV file though - any suggestions on the most sensible way to do this?

  • How can I clear viewstate of a dropdownlist inside a usercontrol? Should I?

    - by tbilly
    I have a web user control with a dropdownlist inside of it. When the usercontrol's databind event is called, it automatically fires the dropdownlists databind event. In the dropdownlist's ondatabound event handler an 'other' option is appended to the end of the dropdownlist. The usercontrol is loaded multiple times, depending on selection of other controls on the page. When the page loads initially, there are no items in the usercontrol except the 'other' option. Then when I call the user control's databind event the control reloads, with 4 items plus the 'other' option. The text for the first item in the list is the 'other' option's text, not what it should be. I've stepped through the databound event of the dropdownlist and have found that all items are loading correctly. It appears that the dropdownlist's viewstate is the culprit, that the dropdownlist's original item[1] text is overwriting the new text. I've tried disabling viewstate on the dropdownlist, but then it wouldn't load at all. Should I try to clear the dropdownlist's viewstate? How do I do that? Any suggestions would be greatly appreciated.

  • Compiling a C++ application on Windows 7, but execute it on Win2003 Server

    - by dabs
    I have a C++ application (quite complex, multiple projects) in Visual Studio 2008, that produces a single dll. Recently I switched to Windows 7, but had previously been compiling under Windows XP. Suddenly the dll in question cannot be loaded by another application, i.e. on a machine running Windows 2003 Server. I've been trying various things: I've installed the VC9.0 redistributable package on the server Also copied various .dll's from that package to the application folder The project is of course compiled in release mode When I run depends.exe on the client machine, I do get the following error: "Error: The Side-by-Side configuration information for "my_dll.dll" contains errors. This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem (14001). Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module." and the icon for shlwapi.dll has a red overlay icon. This didn't happen when I was compiling under WinXP, so I'm guessing that there really is no problem with the .dll's on the client machine, but somewhere there is a reference to that particular version of some dll. Does anyone know what would be the best way to resolve this? Regards, Daníel

  • How do I produce a screenshot of a flash swf on the server?

    - by indignant
    I'm writing a flash app using the open source tools. I would like to load a data file in to the app and capture a screenshot of the stage on the server. The only part that seems mysterious is running the app on the server. In fact, I don't even care if it's the same app running on the server and in the browser--if I can use the flash stage and drawing routines to produce an image server-side, I'm happy. If I have to delve in to flex, fine. Right now I'm having problems finding any starting point at all. I gather Adobe has some commercial products that may fit the bill, but I'd like to stick with open source, apache, and linux. I know this is probably possible with haxe/neko, but I'd like to use more mainstream tools if possible. Am I asking too much? EDIT/CLARIFICATION: Many thanks for the responses so far, but I think I've been a bit muddy in my description. I've already written the actual stage-grabbing stuff using the same PNGEncoder class as was suggested. The problem is in actually running the swf on the server side. I don't want to let the client take the screen shot itself, because this opens up the possibility of the client maliciously submitting a screenshot which does not correspond to what is on the stage, that is, I don't want users uploading porn. If I could run the the actionscript code on the server, then I could generate the screenshot from my data files and be sure that the screenshot matches the data, but I have no idea how to run the actionscript or swf on the server.

  • Does running IIS7 in classic mode affect MVC output caching?

    - by Bob
    I have a need to run an application in classic mode for backwards compatibility with a specific application, and am trying to understand what kind of impact that will have on the performance of an MVC application that is running on the site. If we put a few static file maps (for .js, .css, .png, etc) above the ASP.NET wildcard map to reduce the amount of processing by the ASP.NET handler, will we be approaching the integrated mode in terms of performance? The thing i'm primarily concerned with is any effect this might have on output caching. I understand that integrated mode might (?) allow for the output cache to handle non ASP.NET content, but that isn't really a concern. We're more interested in ensuring that the MVC application has full use of the output cache. Empirically i've found that the two configurations operate on par when things go well, but if the page references resources that are not available, the integrated mode tends to fail much more quickly than the classic mode (e.g. 500 ms vs 10 seconds), reducing 'hang time' on the page load. Thanks for any feedback.

  • How do I avoid having JSONP returns cached in an HTML5 offline application?

    - by Kent Brewster
    I had good luck with cached offline apps until I tried including data from JSONP endpoints. Here's a tiny example, which loads a single movie from the new Netflix widget API: <!DOCTYPE html> <html manifest="main.manifest"> <head> <title>Testing!</title> </head> <body> <p>Attempting to recover a title from Netflix now...</p> <script type="text/javascript"> function ping(r) { alert('API reply: ' + r.catalog_title.title.regular); } var cb = new Date().getTime(); var s = document.createElement('SCRIPT'); s.src = 'http://movi.es/7Soq?v=2.0&output=json&expand=widget&callback=ping&cacheBuster=' + cb; alert('SCRIPT src: ' + s.src); s.type = 'text/javascript'; document.getElementsByTagName('BODY')[0].appendChild(s); </script> </body> </html> ... and here's the contents of my manifest, main.manifest, which contains no files and is only there so my browser knows to cache the calling HTML file. CACHE MANIFEST Yes, I've confirmed that my server is sending the manifest down with the correct content type, text/cache-manifest. The app works fine--meaning both alerts show--the first time I run it, but subsequent runs, even with the attempt at cache-busting in line 10, seem to be attempting to load the script from cache no matter what the query string is. I see the alert showing the script source, but the callback never fires. If I remove the manifest link from line 2 and reset my browser--being Safari and the iPhone Simulator--to clear cache, it works every time. I've also tried alerting the number of SCRIPT tags in the page, and it's definitely seeing both the existing and dynamically-created tag in all cases.

  • How do I override a python import?

    - by Evan Plaice
    So I'm working on pypreprocessor which is a preprocessor that takes c-style directives and I've been able to make it work like a traditional preprocessor (it's self-consuming and executes postprocessed code on-the-fly) except that it breaks library imports. The problem is. The preprocessor runs through the file, processes' it, outputs to a temp file, and exec() the temp file. Libraries that are imported need to be handled a little different because they aren't executed but rather loaded and made accessible to the caller module. What I need to be able to do is. Interrupt the import (since the preprocessor is being run in the middle of the import), load the postprocessed code as a tempModule, and replace the original import with the tempModule to trick the calling script with the import into believing that the tempModule is the original module. I have searched everywhere and so far, have no solution. This question is the closest I've seen so far to providing an answer: http://stackoverflow.com/questions/1096216/override-namespace-in-python Here's what I have. # remove the bytecode file created by the first import os.remove(moduleName + '.pyc') # remove the first import del sys.modules[moduleName] # import the postprocessed module tmpModule = __import__(tmpModuleName) # set first module's reference to point to the preprocessed module sys.modules[moduleName] = tmpModule moduleName is the name of the original module, tmpModuleName is the name of the postprocessed code file. The strange part is, this solution still runs completely normal as if the first module completed loaded normally; unless you remove the last line, then you get a module not found error. Hopefully someone on SO know a lot more about imports than I do because this one has me stumped.

  • Not loading associations without proxies in NHibernate

    - by Alice
    I don't like the idea of proxy and lazy loading. I don't need that. I want pure POCO. And I want to control loading associations explicitly when I need. Here is entity public class Post { public long Id { get; set; } public long OwnerId { get; set; } public string Content { get; set; } public User Owner { get; set; } } and mapping <class name="Post"> <id name="Id" /> <property name="OwnerId" /> <property name="Content" /> <many-to-one name="Owner" column="OwnerId" /> </class> However if I specify lazy="false" in the mapping, Owner is always eagerly fetched. I can't remove many-to-one mapping because that also disables explicit loading or a query like from x in session.Query<Comment>() where x.Owner.Title == "hello" select x; I specified lazy="true" and set use_proxy_validator property to false. But that also eager loads Owner. Is there any way to load only Post entity?

  • Javascript problem with iframe that's hidden before loaded

    - by Aistina
    I have a page that contains an iframe that gets loaded using Javascript: index.html <iframe id="myFrame" width="800" height="600" style="display: none;"></iframe> <div id="loader"><!-- some loading indicator --></div> <script type="text/javascript"> function someFunction() { var myFrame = document.getElementById('myFrame'); var loader = document.getElementById('loader'); loader.style.display = 'block'; myFrame.src = 'myFrame.html'; myFrame.onload = function() { myFrame.style.display = 'block'; loader.style.display = 'none'; }; } </script> The page that gets loaded in the iframe contains some Javascript logic which calculates the sizes of certain elements for the purposes of adding a JS driven scrollbar (jScrollPane + jQuery Dimensions). myFrame.html <div id="scrollingElement" style="overflow: auto;"> <div id="several"></div> <div id="child"></div> <div id="elements"></div> </div> <script type="text/javascript"> $(document).load(function() { $('#scrollingElement').jScrollPane(); }); </script> This works in Chrome (and probably other Webkit browsers), but fails in Firefox and IE because at the time jScrollPane gets called, all the elements are still invisble and jQuery Dimensions is unable to determine any element's dimensions. Is there a way to make sure my iframe is visible before $(document).ready(...) gets called? Other than using setTimeout to delay jScrollPane, which is something I definitely want to avoid.
