  • onmouseover problems with JavaScript (rendered using django and django-imagekit)

    - by Michael Moreno
    I'm using Imagekit. View.py includes: def pics(request): p = Photo.objects.all() return render_to_response('Shots.html', {'p': p}) The following simple code in the template will generate associated images: {% for p in p %} <img src = "{{ p.display.url }}"> <img src = "{{ p.thumbnail_image.url }}"> {% endfor %} I'm attempting to generate a series of thumbnails {{ p.thumbnail_image.url }} which, when mouseover'd, will generate the slightly larger version of the image, {{ p.display.url }} via Javascript. The following code in the template attempts to do so: <html> <head> <HEAD> <script language="Javascript"> { image1 = new Image image2 = new Image image1.src = {{ p.thumbnail_image.url }} image2.src = {{ p.display.url }} </script> </head> <body> {% for p in p %} <a href="" onMouseOver="document.rollover.src= image2.src onMouseOut="document.rollover.src= image1.src"> <img src="{{ p.thumbnail_image.url }}" border=0 name="rollover"></a> {% endfor %} </body> </html> This will display the series of thumbnails, but the larger image will not display when mouseover'd. I believe it has to do with how I'm specifying the variable {{ p.display.url }}.

  • Crash on iOS when system purges memory and closes a UIViewController

    - by Amiramix
    My application is crashing when one of the views is purged from memory because of low-memory condition. At least this is what I understand from the crashlog. It happens on numerous screens but only when opening a Facebook dialog (using the Facebook SDK). Basically, looks like the system sometimes runs out of memory when we need to present a Facebook dialog (e.g. to let user post something on the Facebook timeline). Date/Time: 2012-03-14 19:47:33.819 +0000 OS Version: iPhone OS 5.1 (9B176) Report Version: 104 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x30000008 Crashed Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x30f2bf78 objc_msgSend + 16 1 MyApp 0x00003c0e -LTBaseViewController viewDidUnload (LTBaseViewController.m:145) 2 MyApp 0x00004ea2 -LTBaseTableViewController viewDidUnload (LTBaseTableViewController.m:90) 3 UIKit 0x33766bd8 -[UIViewController unloadViewForced:] + 244 4 UIKit 0x338ae492 -[UIViewController purgeMemoryForReason:] + 58 5 Foundation 0x3071a4f8 __57-NSNotificationCenter addObserver:selector:name:object:_block_invoke_0 + 12 6 CoreFoundation 0x30e95540 ___CFXNotificationPost_block_invoke_0 + 64 7 CoreFoundation 0x30e21090 _CFXNotificationPost + 1400 8 Foundation 0x3068e3e4 -NSNotificationCenter postNotificationName:object:userInfo: + 60 9 Foundation 0x3068fc14 -NSNotificationCenter postNotificationName:object: + 24 10 UIKit 0x3387926a -UIApplication _performMemoryWarning + 74 11 UIKit 0x33879364 -UIApplication _receivedMemoryNotification + 168 12 libdispatch.dylib 0x36a12252 _dispatch_source_invoke + 510 13 libdispatch.dylib 0x36a0fb1e _dispatch_queue_invoke$VARIANT$up + 42 14 libdispatch.dylib 0x36a0fe64 _dispatch_main_queue_callback_4CF$VARIANT$up + 152 15 CoreFoundation 0x30e9c2a6 __CFRunLoopRun + 1262 16 CoreFoundation 0x30e1f49e CFRunLoopRunSpecific + 294 17 CoreFoundation 0x30e1f366 CFRunLoopRunInMode + 98 18 GraphicsServices 0x33fb6432 GSEventRunModal + 130 19 UIKit 0x336f5e76 UIApplicationMain + 1074 20 MyApp 0x00004818 main (main.m:16) 21 MyApp 0x000023b4 0x1000 + 5044 I checked and there are almost no memory leaks, e.g. when testing the app for an hour the total memory leaked was around 2-3Kb caused by some string-copying libraries. So I don't believe this is caused by the application. I guess that when the phone is not restarted for some time there are applications running in the background and when using Facebook SDK the memory becomes a problem and the system tries to recover the memory from random applications, including my application. My question is, how can I prevent this crash from happening? How should I handle unloadViewForced on a view controller to make the app more robust in low-memory conditions? And lastly, am I right that this crashlog suggests the crash occurred because the system tried to free memory and my application didn't handle it properly? Any help greatly appreciated.

  • Problems pulling data from NSMutableArray for MapKit?

    - by Graeme
    Hi, I have a class (DataImporter) which has the code to download an RSS feed. I also have a view and separate class (TableView) which displays the data in a UITableView and starts the parsing process, storing parsed information in an NSMutableArray (items). Now I wish to add a UIMapView which displays the items in the items NSMutableArray. I'm struggling to transfer the data into the new class (mapView) to show it in the map - and I preferably don't want to have to create a new class to download the data again for the map. Is there a way I can transfer the information from the NSMutableArray (items) to the mapView? Thanks. Code for viewDidLoad MapKit: Data *data = nil; NSString *ilocation = [data locations]; NSString *ilocation2 = @"New Zealand"; NSString *inewlString; inewlString = [ilocation stringByAppendingString:ilocation2]; NSLog(@"inewlString=%@",inewlString); if(forwardGeocoder == nil) { forwardGeocoder = [[BSForwardGeocoder alloc] initWithDelegate:self]; } // Forward geocode! [forwardGeocoder findLocation: inewlString]; Code for parsing data into NSMutable Array: - (void)beginParsing { NSLog(@"Parsing has begun"); //self.navigationItem.rightBarButtonItem.enabled = NO; // Allocate the array for song storage, or empty the results of previous parses if (incidents == nil) { NSLog(@"Grabbing array"); self.datas = [NSMutableArray array]; } else { [datas removeAllObjects]; [self.tableView reloadData]; } // Create the parser, set its delegate, and start it. self.parser = [[DataImporter alloc] init]; parser.delegate = self; [parser start]; }

  • How do you keep the text selection on a DataGridView?

    - by fneep
    I'm running C# 2.0, and I've written an application with a DataGridView in virtualmode and a TreeView in the same form, but in different panels of a SplitContainer. My application has a "find all" function that finds all instances of a certain string, and adds them as the child nodes to a new node to the TreeView (it's a tree view because you can have multiple search results by having different root nodes). That idea is that when you click on one of those search results in the TreeView, that it would select the specific text of that result in the DataGridView (Virtually the same as Notepad++'s find all function) When I click on the TreeView, it does set the selected cell of the DataGridView and highlight the specific text, but it loses that specific text selection instantly (but keeps the cell selection) because by clicking on the TreeView the DataGridView loses focus. Here's the code for the AfterSelect of the TreeView: private void Tree_Results_AfterSelect(object sender, TreeViewEventArgs e) { if (e.Node.Level > 0) { SearchResult SelectedItem = (SearchResult)Tree_Results.SelectedNode.Tag; DataViewMain.CurrentCell = DataViewMain[SelectedItem.TypeIndex, SelectedItem.LineIndex]; DataViewMain.BeginEdit(false); DataGridViewTextBoxEditingControl SelectionData = (DataGridViewTextBoxEditingControl)DataViewMain.EditingControl; SelectionData.SelectionStart = SelectedItem.HighlightStart; SelectionData.SelectionLength = SelectedItem.HightlightLength; } } If the DataGridView were a text box I could possibly set HideSelection to false, but DataGridViews have no such property (and changing the Hide Selection for the EditingControl does nothing) Any ideas? I'm receptive to a different control instead of a TreeView that would allow my DataGridView to retain focus.

  • iphone reload tableView

    - by Brodie4598
    In the following code, I have determined that everything works, up until [tableView reloadData] i have NSLOGs set up in the table view delegate methods and none of them are getting called. I have other methods doing the same reloadData and it works perfectly. The only difference tha I am awayre of is tha this is in a @catch block. maybe you smart guys can see something i'm doing wrong... @catch (NSException * e) {////chart is user genrated logoView.image = nil; NSInteger row = [picker selectedRowInComponent:0]; NSString *selectedAircraft = [aircraft objectAtIndex:row]; NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *docsPath = [paths objectAtIndex:0]; NSString *checklistPath = [[NSString alloc]initWithFormat:@"%@/%@.checklist",docsPath,selectedAircraft]; NSString *dataString = [NSString stringWithContentsOfFile:checklistPath encoding: NSUTF8StringEncoding error:NULL]; if ([dataString hasPrefix:@"\n"]) { dataString = [dataString substringFromIndex:1]; } NSArray *tempArray = [dataString componentsSeparatedByString:@"\n"]; NSDictionary *temporaryDictionary = [NSDictionary dictionaryWithObject: tempArray forKey:@"User Generated Checklist"]; self.names = temporaryDictionary; NSArray *tempArray2 = [NSArray arrayWithObject:@"01User Generated Checklist"]; self.keys = tempArray2; aircraftLabel.text = selectedAircraft; checklistSelectPanel.hidden = YES; [tableView reloadData]; }

  • Jquery/YUI - Find image and set CSS to display:none

    - by danit
    I have the following image in a CMS that I want to hide, I dont really want to change source code but would like to hide a specific image which does not have a class applied. Here is the HTML: <td class="right side"> <a title="Show only topic 1" href="view.php?id=3&topic=1"> <img alt="Show only topic 1" src="http://vl3.co.uk/iphone/pix/i/one.gif"/> </a> <br/> </td> I want to hide the <a> and the <img>, bare in mind the title and alt tag can be different so cant use that as an identifier. I presume I could use .find() and then use .parent() to set the <a> to display: none; thus hiding the img? Im inlcuding the jQuery library, however the CMS has YUI included out of the box so if anyone has a YUI method it would be appreicated.

  • NSFetchedResultsController: changing predicate not working?

    - by icerelic
    Hi, I'm writing an app with two tables on one screen. The left table is a list of folders and the right table shows a list of files. When tapped on a row on the left, the right table will display the files belonging to that folder. I'm using Core Data for storage. When the selection of folder changes, the fetch predicate of the right table's NSFetchedResultsController will change and perform a new fetch, then reload the table data. I used the following code snippet: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"list = %@",self.list]; [fetchedResultsController.fetchRequest setPredicate:predicate]; NSError *error = nil; if (![[self fetchedResultsController] performFetch:&error]) { NSLog(@"Unresolved error %@, %@", error, [error userInfo]); abort(); } [table reloadData]; However the fetch results are still the same. I've NSLog'ed "predicate" before and after the fetch, and they were correct with updated information. The fetch results stay the same as initial fetch (when view is loaded). I'm not very familiar with the way Core Data fetches objects (is there a caching system?), but I've done similar things before(changing predicates, re-fetching data, and refreshing table) with single table views and everything went well. If someone could gave me a hint I would be very appreciated. Thanks in advance.

  • Prevent empty tooltips at a wpf datagrid

    - by TheCalendarProgrammer
    I am working on a calendar program, which consists mainly of a WPF DataGrid. As there is not always enough space to display all the entries of a day (which is a DataGridCell), a tooltip with all the entries of the day shell appear at mouse over. This works so far with the code snippet shown below. And now the (little) problem: If there are no entries for a day, no tooltip shell pop up. With the code below an empty tooltip pops up. <DataGridTemplateColumn x:Name="Entry" IsReadOnly="True"> <DataGridTemplateColumn.CellTemplate> <DataTemplate> <Grid> <TextBlock Text="{Binding EntryText}" Foreground="{Binding EntryForeground}" FontWeight="{Binding EntryFontWeight}"> </TextBlock> <TextBlock Text="{Binding RightAlignedText}" Foreground="Gray" Background="Transparent"> <TextBlock.ToolTip> <TextBlock Text="{Binding AllEntriesText}"/> </TextBlock.ToolTip> </TextBlock> </Grid> </DataTemplate> </DataGridTemplateColumn.CellTemplate> </DataGridTemplateColumn> The Databinding is made via myCalDataGrid.Itemssource = _listOfDays; in code behind, where a 'Day' is the view model for a single calendar row.

  • SQL query using information from 4 tables (not all directly linked)

    - by Yvonne
    I'm developing a simple classroom system, where teachers manage classes and their subjects. I have 2 levels of access in my teachers table, assigned by an integer (1 = admin, 2 = user)... Meaning that the headteacher is the admin :) A teacher (of level 1) can have have many classes and a class can have many teachers (so I have 'TeachersClasses' table). A class can have many subjects, and a teacher can have many subjects. Basically, I'm attempting a query to display the admin teacher's (level 1) subjects. However, only teachers with a level of 2, are directly related to a subject, which is set by the admin user. The headteacher can view all of their subjects via the classroom, but I cannot get all of the subjects to be displayed on one page, instead I can only get the subjects to appear under a specific classroom right now... This is what I have so far, which is returning nothing. (I'm guessing this may require an SQL clause more advanced that 'INNER JOIN' which is the only join type I am familiar with, and thought it would be enough! $query = "SELECT subjects.subjectid, subjects.subjectname, subjects.subjectdetails, classroom.classid, classroom.classname FROM subjects INNER JOIN classroom ON subjects.subjectid = classroom.classid INNER JOIN teacherclasses ON classroom.classid = teacherclasses.classid INNER JOIN teachers ON teacherclasses.teacherid = teachers.teacherid WHERE teachers.teacherid = '".intval( $_SESSION['SESS_TEACHERID'] )."'"; In order for all subjects related to the headteachers class to be displayed, I'm gathering that all of my tables will need to be called up here? Thanks for any help! Example output: subject name: maths // teacher: mr smith // classroom: DG99 x10 for all the subjects associated with the headteachers classrooms :)

  • Can I perform some processing on the POST data before ASP.NET MVC UpdateModel happens?

    - by Domenic
    I would like to strip out non-numeric elements from the POST data before using UpdateModel to update the copy in the database. Is there a way to do this? // TODO: it appears I don't even use the parameter given at all, and all the magic // happens via UpdateModel and the "controller's current value provider"? [HttpPost] public ActionResult Index([Bind(Include="X1, X2")] Team model) // TODO: stupid magic strings { if (this.ModelState.IsValid) { TeamContainer context = new TeamContainer(); Team thisTeam = context.Teams.Single(t => t.TeamId == this.CurrentTeamId); // TODO HERE: apply StripWhitespace() to the data before using UpdateModel. // The data is currently somewhere in the "current value provider"? this.UpdateModel(thisTeam); context.SaveChanges(); this.RedirectToAction(c => c.Index()); } else { this.ModelState.AddModelError("", "Please enter two valid Xs."); } // If we got this far, something failed; redisplay the form. return this.View(model); } Sorry for the terseness, up all night working on this; hopefully my question is clear enough? Also sorry since this is kind of a newbie question that I might be able to get with a few hours of documentation-trawling, but I'm time-pressured... bleh.

  • ASP.NET MVC 2 strange behavior

    - by Voice
    Hi Recently I installed VS 2010 Release (migrated from RC) and my MVC application is not working anymore. More concrete: I have a wizard with several steps for new customer account creation (Jquery form wizard, but it doesn't really matter). Each step contains a typed partial View for each part of account: Company, Customer, Licence, etc. When I submit the form I see really strange thing in ModelState. There are duplicate keys for Company: with "Company" prefix and without it. Something like this: [6] "Company.Phone" string [12] "Phone" string My model state for all these keys is not valid because Company is actually null and validation fails. When it was RC there were no such keys with "Company" prefix. So these keys in ModelState with prefix "Company" appeared after I installed VS Release. Here is my code: Main View <div id="registerSteps"> <div id="firstStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CustomerInfo) %></legend> <% Html.RenderPartial("CustomerInfo", ViewData["newCust"]); %> </fieldset> </div> <div id="secondStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.CompanyInfo) %></legend> <% Html.RenderPartial("CompanyInfo", ViewData["newComp"]); %> </fieldset> </div> <div id="thirdStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.LicenceInfo) %></legend> <% Html.RenderPartial("LicenceInfo", ViewData["newLic"]); %> </fieldset> </div> <div id="lastStep" class="step"> <fieldset> <legend><%=Html.Encode(Register.PrivacyStatement) %></legend> <% Html.RenderPartial("PrivacyStatementInfo"); %> </fieldset> </div> <div id="registerNavigation"> <input class="navigation_button" value="Back" type="reset"/> <input class="navigation_button" value="Next" type="submit"/> </div> </div> Two partial views (to show that they are actually identical): Company: <div id="dCompanyInfo"> <div> <div> <%=Html.LocalizableLabelFor(company => company.Name, Register.CompanyName) %> </div> <div> <%=Html.TextBoxFor(company => company.Name) %> <%=Html.ValidationMessageFor(company => company.Name) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Phone, Register.Phone) %> </div> <div> <%=Html.TextBoxFor(company => company.Phone) %> <%=Html.ValidationMessageFor(company => company.Phone) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Fax, Register.Fax) %> </div> <div> <%=Html.TextBoxFor(company => company.Fax) %> <%=Html.ValidationMessageFor(company => company.Fax) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Size_ID, Register.CompanySize) %> </div> <div> <%=Html.ValueListDropDown(company => company.Size_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["CompSize"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Size_ID) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(company => company.Industry_ID, Register.Industry) %> </div> <div> <%=Html.ValueListDropDown(company => company.Industry_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["Industry"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(company => company.Industry_ID) %> </div> </div> </div> And for Customer <div id="dCustomerInfo"> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Email, Register.Email) %> </div> <div> <%=Html.TextBoxFor(customer => customer.Email) %> <%=Html.ValidationMessageFor(customer => customer.Email) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Male, Register.Gender) %> </div> <div> <%=Html.ListBoolEditor(customer => customer.Male, Register.Male, Register.Female, Register.GenderOptionLabel) %> <%=Html.ValidationMessageFor(customer => customer.Male) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.FirstName, Register.FirstName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.FirstName) %> <%=Html.ValidationMessageFor(customer => customer.FirstName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.LastName, Register.LastName) %> </div> <div> <%=Html.TextBoxFor(customer => customer.LastName) %> <%=Html.ValidationMessageFor(customer => customer.LastName) %> </div> </div> <div> <div> <%=Html.LocalizableLabelFor(customer => customer.Role_ID, Register.Role) %> </div> <div> <%=Html.ValueListDropDown(customer => customer.Role_ID, (CodeRoad.AQua.DomainModel.ValueList)ViewData["OrgRole"], (string)ViewData["Culture"]) %> <%=Html.ValidationMessageFor(customer => customer.Role_ID) %> </div> </div> </div> There are some home made extension methods, but they worked pretty well in previous version (VS RC). Html which is generated is also ok, no "Company.Phone"-like stuff. So I wonder, where all these keys with "Company" came from and what can I do with that? I appreciate any solution.

  • Inheritance of list-style-type property in Firefox (bug in Firebug?)

    - by Marcel Korpel
    Let's have a look at some comments on a page generated by Wordpress (it's not a site I maintain, I'm just wondering what's going on here). As these pages might disappear in the near future, I've put some screenshots online. Here's what I saw: Obviously, the list-item markers shouldn't be there. So I decided to look at the source using Firebug. As you can see, Firebug claims that the list-style property (containing none) is inherited from ol.commentlist. But if that's the case, why are the circle and the square visible? When checking the computed style, Firebug shows the list-style-types correctly. What's the correct behaviour? I just did a quick check in Chromium, whose Web Inspector gave a better view of reality (the list item markers were also displayed in this browser): According to WebKit, list-style of ol.commentlist isn't inherited, only the default value of list-style-type from the rendering engine. So, we may conclude that the output of both browsers is correct and that Firefox (Firebug) shows an incorrect representation of inherited styles. What does the CSS specification say? Inheritance will transfer the list-style values from OL and UL elements to LI elements. This is the recommended way to specify list style information. Not much about the inheritance of ol properties to uls. Is Firebug wrong in this respect? BTW, I managed to let the markers disappear by just changing line 312 of style.css to ol.commentlist, li.commentlist, ul.children { When also explicitly defining the list-style of ul.children to none, the markers are not painted. You can have a look at screenshots of Firebug and WebKit's Web Inspector in this case, if you like.

  • What is the difference between cubes and the Unified Dimensional Model (if any)?

    - by ngm
    I'm currently researching SQL Server 2008 as a business intelligence solution, and currently looking at Analysis Services (and I'm pretty new to business intelligence as a whole...) I'm a bit confused by some of the terms in SSAS, particularly the conceptual differences between cubes and MS's Unified Dimensional Model. I believe that a cube in SSAS is basically an OLAP cube -- dimensions, measures, something that sits between the underlying data source and a business user. But then that's kind of what I understand UDM to be as well. The docs for SQL Server 2005 seem to suggest as much: "A cube is essentially synonymous with a Unified Dimensional Model (UDM)". But then the SQL Server 2008 pages sort of suggest that UDM is a wrapper for both multidimensional data (cubes) and relational data: "Use the Unified Dimensional Model to provide one consolidated business view for relational and multidimensional data that includes business entities, business logic, calculations, and metrics." This blog post suggests similarly: "UDM provides a single dimensional model for all OLAP analysis and relational reporting needs. So you can use either MDX or SQL" Is UDM something that sits above cubes? Or are they the same thing? I presume I would develop cubes with the Cube Designer application; what would I develop a UDM with?

  • lnk2019 error in very simple c++ program

    I have tried removing various parts and building, but nothing makes the lnk2019 error go away, or even produces any normal errors. Everything is in the one file at the moment (it won't be later when it is finished).

  • adding header row to gridview won't allow you to save the last item row

    - by Lex
    I've modified my GridView to have an extra Header row, however that extra row has caused my grid view row count to be incorrect. Basically, when I want to save the Gridview now, it doesn't recognize the last item line. In my current test I have 5 Item Lines, however only 4 of them are being saved. My code for creating the additional header Line: protected void gvStatusReport_RowDataBound(object sender, GridViewRowEventArgs e) { // This grid has multiple rows, fake the top row. if (e.Row.RowType == DataControlRowType.Header) { SortedList FormatCells = new SortedList(); FormatCells.Add("1", ",6,1"); FormatCells.Add("2", "Time Spent,7,1"); FormatCells.Add("3", "Total,2,1"); FormatCells.Add("4", ",6,1"); GetMultiRowHeader(e, FormatCells); } } The function to create a new row: public void GetMultiRowHeader(GridViewRowEventArgs e, SortedList GetCels) { GridViewRow row; IDictionaryEnumerator enumCels = GetCels.GetEnumerator(); row = new GridViewRow(-1, -1, DataControlRowType.Header, DataControlRowState.Normal); while (enumCels.MoveNext()) { string[] count = enumCels.Value.ToString().Split(Convert.ToChar(",")); TableCell cell = new TableCell(); cell.RowSpan = Convert.ToInt16(count[2].ToString()); cell.ColumnSpan = Convert.ToInt16(count[1].ToString()); cell.Controls.Add(new LiteralControl(count[0].ToString())); cell.HorizontalAlign = HorizontalAlign.Center; row.Cells.Add(cell); } e.Row.Parent.Controls.AddAt(0, row); } Then when I'm going to save, I loop through the rows: int totalRows = gvStatusReport.Rows.Count; for (int rowNumber = 0; rowNumber < totalRows; rowNumber++) { However the first line doesn't seem to have any of the columns that the item row has, and the last line doesn't even show up. My problem is that I do need the extra header line, but what is the best way to fix this?

  • Maintaining state and data context between requests in ASP.NET + EF4

    - by Nick
    I have a EF4/ASP.NET web application that is structured to use POCOs and generic repositories, based essentially on this excellent article. The application is relatively sophisticated with one page that involves selection and linking of multiple entities to build up a complex user profile. This requires access to multiple entity types (20 or so) and associated repositories across multiple posts. When a repository is first accessed it uses the existing data context if exists, else it creates a new context. The problem is that if the lifetime of the context is only per-request (as suggested in the article) then you have to deal with multiple contexts and the complexity around detaching and attaching entities from contexts. My solution is to share the context between posts by creating a single View Model that includes all required repositories (initialised to share the same context) plus any associated data and store this model in a Session variable, retrieving from Session on subsequent page requests. Therefore maintaining the same context across all posts until the profile is saved. This works fine BUT I am concerned that I don't actually know exactly what is stored in the model session variable or more importantly the size of the Session variable. So two questions I suppose: firstly should I look for a better solution to handle the shared context across posts issue (any suggestions welcome)? And secondly what is actually stored in the Session when it includes a repository plus context? Any help appreciated!

  • Eclipse CDT: cannot debug or terminate application

    - by Paul Lammertsma
    I have Eclipse set up fairly nicely to run the G++ compiler through Cygwin. Even the character encoding is set up correctly! There still seems to be something wrong with my configuration: I can't debug. The pause button in the debug view is simply disabled, and no threads appear in my application tree. It seems that gdb is simply not communicating with Eclipse. Presently, I have the debug settings as follows: Debugger: "Cygwin gdb Debugger" GDB debugger: gdb GDB command file: .gdbinit Protocol: Default I should mention here that I have no idea what .gdbinit does; in my project it is merely an empty file. What is wrong with my configuration? Debugging When attempting to terminate the application in debug mode, Eclipse displays the following error: Target request failed: failed to interrupt. I can't kill the process, either; I have to kill its parent gdb.exe, which in turn kills my application. Running When running it normally, a bunch of kill.exes are called, doing nothing, while Eclipse displays the following error: Terminate failed. I can kill FaceDetector.exe from the task manager. Process Explorer This is what it looks like in Process Explorer (debugging left, running right):

  • Objecive C Error, Message sent to deallocated object

    - by Dave C
    Hello, I have several buttons on my app that are being created dynamically. They are all pointed at the button click event when pressed. When the button pressed method is called, the sender's tag(int value) is parsed into the controllers house ID. It works with one of the buttons... the first one created to be specific, but the others throw the following error: -[CFNumber intValue]: message sent to deallocated instance 0xc4bb0ff0 I am not releasing these buttons anywhere in my code... I haven't set them to auto release or anything like that... just wondering why they are doing this on the click. The button click event: - (IBAction) ButtonClick: (id) sender { HouseholdViewController *controller = [[HouseholdViewController alloc] initWithNibName:@"HouseholdViewController" bundle:nil]; controller.delegate = self; controller.HouseID = [(NSInteger)[(UIButton *)sender tag] intValue]; //this line throws an error controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Where I am creating the buttons: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(MyLongInScreenCoords, MyLatInScreenCoords, 50, 50); UIImage *buttonImageNormal = [UIImage imageNamed:@"blue_pin.png"]; UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:50 topCapHeight:50]; [button setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal]; [self.view addSubview:button]; button.tag = [NSNumber numberWithInt:[[words objectAtIndex: i] intValue]]; ButtonPoints[CurrentHouseCount][0] = button; ButtonPoints[CurrentHouseCount][1] = [NSValue valueWithCGPoint:CGPointMake(MyActualLat, MyActualLong)]; [button addTarget:self action:@selector(ButtonClick:) forControlEvents:UIControlEventTouchUpInside]; CurrentHouseCount++; Thank you for any assistance.

  • How can Safari be prevented from scrolling an overflow:hidden iframe?

    - by Alexander Ljungberg
    With Safari you can disable most iframe scrolling by setting style="overflow: hidden;" on the iframe. However, if you click in the iframe and move the mouse the content scrolls anyhow. Example: <html> <body> <iframe style="width: 100%; height:100px; overflow: hidden;" scrolling="no" src="scrollcontent.html"> </iframe> </body> </html> scrollcontent.html: <html scroll="no" style="overflow:hidden;"> <body scroll="no" style="overflow:hidden;"> <div style="background-color: green; height:100px;">A</div> <div style="background-color: red; height:100px;">B</div> </body> </html> In this example, the iframe should only show a green area and it should be impossible to reveal the red area. This is mostly true: there is no scrollbar, the mouse wheel doesn't do anything and neither do the arrow keys. However click and drag still scrolls the view. This is particularly noticeable when selecting text. Does anyone know any trick to stop Safari from doing this?

  • correct way to create a pivot table in postgresql using CASE WHEN

    - by mojones
    I am trying to create a pivot table type view in postgresql and am nearly there! Here is the basic query: select acc2tax_node.acc, tax_node.name, tax_node.rank from tax_node, acc2tax_node where tax_node.taxid=acc2tax_node.taxid and acc2tax_node.acc='AJ012531'; And the data: acc | name | rank ----------+-------------------------+-------------- AJ012531 | Paromalostomum fusculum | species AJ012531 | Paromalostomum | genus AJ012531 | Macrostomidae | family AJ012531 | Macrostomida | order AJ012531 | Macrostomorpha | no rank AJ012531 | Turbellaria | class AJ012531 | Platyhelminthes | phylum AJ012531 | Acoelomata | no rank AJ012531 | Bilateria | no rank AJ012531 | Eumetazoa | no rank AJ012531 | Metazoa | kingdom AJ012531 | Fungi/Metazoa group | no rank AJ012531 | Eukaryota | superkingdom AJ012531 | cellular organisms | no rank What I am trying to get is the following: acc | species | phylum AJ012531 | Paromalostomum fusculum | Platyhelminthes I am trying to do this with CASE WHEN, so I've got as far as the following: select acc2tax_node.acc, CASE tax_node.rank WHEN 'species' THEN tax_node.name ELSE NULL END as species, CASE tax_node.rank WHEN 'phylum' THEN tax_node.name ELSE NULL END as phylum from tax_node, acc2tax_node where tax_node.taxid=acc2tax_node.taxid and acc2tax_node.acc='AJ012531'; Which gives me the output: acc | species | phylum ----------+-------------------------+----------------- AJ012531 | Paromalostomum fusculum | AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | Platyhelminthes AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | AJ012531 | | Now I know that I have to group by acc at some point, so I try select acc2tax_node.acc, CASE tax_node.rank WHEN 'species' THEN tax_node.name ELSE NULL END as sp, CASE tax_node.rank WHEN 'phylum' THEN tax_node.name ELSE NULL END as ph from tax_node, acc2tax_node where tax_node.taxid=acc2tax_node.taxid and acc2tax_node.acc='AJ012531' group by acc2tax_node.acc; But I get the dreaded ERROR: column "tax_node.rank" must appear in the GROUP BY clause or be used in an aggregate function All the previous examples I've been able to find use something like SUM() around the CASE statements, so I guess that is the aggregate function. I have tried using FIRST(): select acc2tax_node.acc, FIRST(CASE tax_node.rank WHEN 'species' THEN tax_node.name ELSE NULL END) as sp, FIRST(CASE tax_node.rank WHEN 'phylum' THEN tax_node.name ELSE NULL END) as ph from tax_node, acc2tax_node where tax_node.taxid=acc2tax_node.taxid and acc2tax_node.acc='AJ012531' group by acc2tax_node.acc; but get the error: ERROR: function first(character varying) does not exist Can anyone offer any hints?

  • Compile and optimize for different target architectures

    - by Peter Smit
    Summary: I want to take advantage of compiler optimizations and processor instruction sets, but still have a portable application (running on different processors). Normally I could indeed compile 5 times and let the user choose the right one to run. My question is: how can I can automate this, so that the processor is detected at runtime and the right executable is executed without the user having to chose it? I have an application with a lot of low level math calculations. These calculations will typically run for a long time. I would like to take advantage of as much optimization as possible, preferably also of (not always supported) instruction sets. On the other hand I would like my application to be portable and easy to use (so I would not like to compile 5 different versions and let the user choose). Is there a possibility to compile 5 different versions of my code and run dynamically the most optimized version that's possible at execution time? With 5 different versions I mean with different instruction sets and different optimizations for processors. I don't care about the size of the application. At this moment I'm using gcc on Linux (my code is in C++), but I'm also interested in this for the Intel compiler and for the MinGW compiler for compilation to Windows. The executable doesn't have to be able to run on different OS'es, but ideally there would be something possible with automatically selecting 32 bit and 64 bit as well. Edit: Please give clear pointers how to do it, preferably with small code examples or links to explanations. From my point of view I need a super generic solution, which is applicable on any random C++ project I have later. Edit I assigned the bounty to ShuggyCoUk, he had a great number of pointers to look out for. I would have liked to split it between multiple answers but that is not possible. I'm not having this implemented yet, so the question is still 'open'! Please, still add and/or improve answers, even though there is no bounty to be given anymore. Thanks everybody!
