  • Re-ordering C++ template functions

    - by DeadMG
    In C++, I have a certain template function that, on a given condition, calls a template function in another class. The trouble is that the other class requires the full definition of the first class to be implemented, as it creates the second class and stores them and manages them in similar fashions. The trouble is that naturally, they fall as one class, and thus have some tight interop, except that I need them to be two classes for threading reasons. A sort of, master for all threads, one child per thread, system. Any advice on how this can be implemented?

  • Django: ordering numerical value with order_by

    - by h3
    I'm in a situation where I must output a quite large list of objects by a CharField used to store street addresses. My problem is, that obviously the data is ordered by ASCII codes since it's a Charfield, with the predictable results .. it sort the numbers like this; 1, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 2, 20, 21.... Now the obvious step would be to change the Charfield the proper field type (IntegerField let's say), however it cannot work since some address might have apartments .. like "128A". I really don't know how I can order this properly ..

  • Ordering of reflection requests in dotnet

    - by happyclicker
    When I call GetProperties() on a type, the properties are ordered as they are written in the source code. This is very handy but my question is, if this is a guaranteed behavior or may this change depending on the runtime version and the environment. Does anyone know something about that?

  • Ordering z-indexes in an array

    - by Tom Gullen
    I have an array which looks something along the lines of resourceData[0][0] = "pic1.jpg"; resourceData[0][1] = 5; resourceData[1][0] = "pic2.jpg"; resourceData[1][1] = 2; resourceData[2][0] = "pic3.jpg"; resourceData[2][1] = 900; resourceData[3][0] = "pic4.jpg"; resourceData[3][1] = 1; The numeric represents the z-index of the image. Minimum z-index value is 1. Maximum (not really important) is 2000. I have all the rendering and setting z-indexes done fine. My question is, I want to have four functions: // Brings image to z front function bringToFront(resourceIndex) { // Set z-index to max + 1 resourceData[resourceIndex][1] = getBiggestZindex() + 1; // Change CSS property of image to bring to front $('#imgD' + resourceIndex).css("z-index", resourceData[resourceIndex][1]); } function bringUpOne(resourceIndex) { } function bringDownOne(resourceIndex) { } // Send to back z function sendToBack(resourceIndex) { } So given then index [3] (900 z): If we send it to the back, it will take the value 1, and [3] will have to go to 2, but that conflicts with [1] who has a 2 z-index so they need to go to three etc. Is there an easy programatical way of doing this because as soon as I start doing this it's going to get messy. It's important that the indexes of the array don't change. We can't sort the array unfortunately due to design. Update Thanks for answers, I'll post the functions here once they are written incase anyone comes across this in the future (note this code has zindex listed in [6]) // Send to back z function sendToBack(resourceIndex) { resourceData[resourceIndex][6] = 1; $('#imgD' + resourceIndex).css("z-index", 1); for (i = 0; i < resourceData.length; i++) { if (i != resourceIndex) { resourceData[i][6]++; $('#imgD' + i).css("z-index", resourceData[i][6]); } } }

  • Joining two select queries and ordering results

    - by user1
    Basically I'm just unsure as to why this query is failing to execute: (SELECT replies.reply_post, replies.reply_content, replies.reply_date AS d, members.username FROM (replies) AS a INNER JOIN members ON replies.reply_by = members.id) UNION (SELECT posts.post_id, posts.post_title, posts.post_date AS d, members.username FROM (posts) as b WHERE posts.post_set = 0 INNER JOIN members ON posts.post_by = members.id) ORDER BY d DESC LIMIT 5 I'm getting this error: #1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'a INNER JOIN members ON replies.re' at line 2 All I'm trying to do is select the 5 most recent rows (dates) from these two tables. I've tried Join, union etc and I've seen numerous queries where people have put another query after the FROM statement and that just makes no logical sense to me as to how that works? Am I safe to say that you can join the same table from two different but joined queries? Or am I taking completely the wrong approach, because frankly I can't seem see how this query is failing despite reading the error message. (The two queries on there own work fine)

  • IQueryable<> dynamic ordering/filtering with GetValue fails

    - by MyNameIsJob
    I'm attempting to filter results from a database using Entity Framework CTP5. Here is my current method. IQueryable<Form> Forms = DataContext.CreateFormContext().Forms; foreach(string header in Headers) { Forms = Forms.Where(f => f.GetType() .GetProperty(header) .GetValue(f, null) .ToString() .IndexOf(filter, StringComparison.InvariantCultureIgnoreCase) >= 0); } However, I found that GetValue doesn't work using Entity Framework. It does when the type if IEnumerable< but not IQueryable< Is there an alternative I can use to produce the same effect?

  • Ordering by number of rows?

    - by Rob
    Alright, so I have a table outputting data from a MySQL table in a while loop. Well one of the columns it outputs isn't stored statically in the table, instead it's the sum of how many times it appears in a different MySQL table. Sorry I'm not sure this is easy to understand. Here's my code: $query="SELECT * FROM list WHERE added='$addedby' ORDER BY time DESC"; $result=mysql_query($query); while($row=mysql_fetch_array($result, MYSQL_ASSOC)){ $loghwid = $row['hwid']; $sql="SELECT * FROM logs WHERE hwid='$loghwid' AND time < now() + interval 1 hour"; $query = mysql_query($sql) OR DIE(mysql_error()); $boots = mysql_num_rows($query); //Display the table } The above is the code displaying the table. As you can see it's grabbing data from two different MySQL tables. However I want to be able to ORDER BY $boots DESC. But as its a counting of a completely different table, I have no idea of how to go about doing that. I would appreciate any help, thank you.

  • ordering a collection by an association's property

    - by neiled
    class Person belongs_to :team class Status #has last_updated property class Team has_many :members, :class => "Person" Ok, so I have a Team class which has many People in it and each of those people has a status and each status has a last_updated property. I'm currently rendering a partial with a collection similar to: =render :partial => "user", :collection => current_user.team.members Now how do I go about sorting the collection by the last_updated property of the Status class? Thanks in advance! p.s. I've just written the ruby code from memory, it's just an example, it's not meant to compile but I hope you get the idea!

  • ordering by a property on a joined table linq to sql

    - by Gazeth
    I have the following linq query from o in context.Opportunities join i in context.Interactions on o.OpportunityID equals i.OpportunityID into ints from i in ints.DefaultIfEmpty() orderby i.StatusID descending, o.StatusID descending select o Now i want to then do a distinct on the opportunities table but doing so removes my orderby. I know that you can do Distinct().OrderBy but how do i get a reference to the interactions table that was joined when I'm only selecting the opportunity entity?

  • Loading multiple embedded flash apps onto an HTML page- problem with ordering

    - by shudson250
    We need to load an embedded version of a site written in Flash, and not originally designed to load multiple instances of itself, on a HTML page. The specific issue is how to get them to load in order when embedded, given that they are all being opened by the same instance of the flash player. It's a complicated mapping application, and at the moment, the maps and data get intermixed as the session variables are overwritten by another instance starting to load before the previous one has finished. We need a way to have them load sequentially, one finishing before another starts to load. The most we can specify in the URL is an &order=1 or similar. We have PHP and SQL on the backend. Edit: The embedded versions are being loaded in an iFrame of a parent site. One php file loads one swf, as many times as the parent site desires.

  • Ordering a set of lines so that they follow one from the other

    - by george
    Line# Lat.

The lines are not listed in sequence because I don't know what the correct sequence is just by looking at the coordinates (unless I look at the lines in a map). Hence my question: how can I find programmatically (in Python) what the correct sequence is, so I can join the lines into one long line, keeping in mind the following problem: - a 'z' point (the last point in a line) may well be the first point if the line is described as proceeding in the opposite direction to other lines. e.g. one line may go from left to right, another from right to left (or top to bottom and viceversa). Thank you in advance...

  • Showing login view controller before main tab bar controller

    - by Padawan
    I'm creating an iPad app with a tab bar controller that requires login. So on launch, I want to show a LoginViewController and if login is successful, then show the tab bar controller. This is how I implemented an initial test version (left out some typical header stuff, etc)... AppDelegate.h: @interface AppDelegate_Pad : NSObject <UIApplicationDelegate, LoginViewControllerDelegate> { UIWindow *window; UITabBarController *tabBarController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UITabBarController *tabBarController; @end AppDelegate.m: @implementation AppDelegate_Pad @synthesize window; @synthesize tabBarController; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { LoginViewController_Pad *lvc = [[LoginViewController_Pad alloc] initWithNibName:@"LoginViewController_Pad" bundle:nil]; lvc.delegate = self; [window addSubview:lvc.view]; //[lvc release]; [window makeKeyAndVisible]; return YES; } - (void)loginViewControllerDidFinish:(LoginViewController_Pad *)loginViewController { [window addSubview:tabBarController.view]; } - (void)dealloc {...} @end LoginViewController_Pad.h: @protocol LoginViewControllerDelegate; @interface LoginViewController_Pad : UIViewController { id<LoginViewControllerDelegate> delegate; } @property (nonatomic, assign) id <LoginViewControllerDelegate> delegate; - (IBAction)buttonPressed; @end @protocol LoginViewControllerDelegate -(void)loginViewControllerDidFinish:(LoginViewController_Pad *)loginViewController; @end LoginViewController_Pad.m: @implementation LoginViewController_Pad @synthesize delegate; ... - (IBAction)buttonPressed { [self.view removeFromSuperview]; [self.delegate loginViewControllerDidFinish:self]; } ... @end So the app delegate adds the login view controller's view on launch and waits for login to call "did finish" using a delegate. The login view controller calls removeFromSuperView before it calls didFinish. The app delegate then calls addSubView on the tab bar controller's view. If you made it up to this point, thanks, and I have three questions: MAIN QUESTION: Is this the right way to show a view controller before the app's main tab bar controller is displayed? Even though it seems to work, is it a proper way to do it? If I comment out the "lvc release" in the app delegate then the app crashes with EXC_BAD_ACCESS when the button on the login view controller is pressed. Why? With the "lvc release" commented out everything seems to work but on the debugger console it writes this message when the app delegate calls addSubView for the tab bar controller: Using two-stage rotation animation. To use the smoother single-stage animation, this application must remove two-stage method implementations. What does that mean and do I need to worry about it?

  • Shift+Tab not working in TreeView control

    - by Christian
    I cannot get backwards navigation using Shift+Tab to work in a TreeView that contains TextBoxs, forward navigation using Tab works fine and jump from TextBox to TextBox inside the TreeView. Anytime Shift+Tab is used when one of the TextBoxes inside the TreeView, then the focus is move to the previous control outside the TreeView, instead of the previous control inside the TreeView. Also its only Shift+Tab navigation that are not working correctly, Ctrl+Shift+Tab work as expected and in the correct order. Any suggestions to what I'm doing wrong? Example code: <Window x:Class="TestTabTreeView.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Window.Resources> <Style TargetType="TreeViewItem"> <Setter Property="KeyboardNavigation.TabNavigation" Value="Continue" /> </Style> </Window.Resources> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <TextBox Text="First Line" Grid.Row="0" /> <TreeView Grid.Row="1" KeyboardNavigation.TabNavigation="Continue" IsTabStop="False"> <TreeViewItem IsExpanded="True"><TreeViewItem.Header><TextBox Text="Popular Words"/></TreeViewItem.Header> <TreeViewItem><TreeViewItem.Header><TextBox Text="Foo"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Bar"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Hello"/></TreeViewItem.Header></TreeViewItem> </TreeViewItem> <TreeViewItem IsExpanded="True"><TreeViewItem.Header><TextBox Text="Unpopular Words"/></TreeViewItem.Header> <TreeViewItem><TreeViewItem.Header><TextBox Text="Work"/></TreeViewItem.Header></TreeViewItem> <TreeViewItem><TreeViewItem.Header><TextBox Text="Duplication"/></TreeViewItem.Header></TreeViewItem> </TreeViewItem> </TreeView> <TextBox Text="Last Line" Grid.Row="2" /> </Grid>

  • iPhone:Tabbar hides when pushing from TableView to UIViewController

    - by user187532
    Hello all, I have four Tab bar items in a Tab bar which is being bottom of the view where i have the TableView. I am adding Tab bar and items programmatically (Refer below code) not through I.B. Click on first three Tab bar items, will show the data in the same TableView itself. But clicking on last Tab bar items will push to another UIViewcontroller and show the data there. The problem here is, when i push to the viewController when clicking on last Tab bar item, main "Tab bar" is getting removed. Tab bar code: UITabBar *tabBar = [[UITabBar alloc] initWithFrame:CGRectMake(0, 376, 320, 44)]; item1 = [[UITabBarItem alloc] initWithTitle:@"First Tab" image:[UIImage imageNamed:@"first.png"] tag:0]; item2 = [[UITabBarItem alloc] initWithTitle:@"Second Tab" image:[UIImage imageNamed:@"second.png"] tag:1]; item3 = [[UITabBarItem alloc] initWithTitle:@"Third Tab" image:[UIImage imageNamed:@"third.png"] tag:2]; item4 = [[UITabBarItem alloc] initWithTitle:@"Fourth Tab" image:[UIImage imageNamed:@"fourth.png"] tag:3]; item5 = [[UITabBarItem alloc] initWithTitle:@"Fifth Tab" image:[UIImage imageNamed:@"fifth.png"] tag:4]; NSArray *items = [NSArray arrayWithObjects: item1,item2,item3,item4, item5, nil]; [tabBar setItems:items animated:NO]; [tabBar setSelectedItem:item1]; tabBar.delegate=self; [self.view addSubview:tabBar]; Push controller code clicking from last Tab bar item: myViewController = [ [MyViewController alloc] initWithNibName:@"MyView" bundle:nil]; myViewController.hidesBottomBarWhenPushed=NO; [[self navigationController] pushViewController:myViewController animated:NO]; I am not seeing bottom Tab bar when i push my current TableView to myViewController. I am seeing full screen view there. I want to see bottom Tab bar always when every tab item clicked. What might be the problem here? Could someone who come across this issue, please share your suggestion to me? Thank you.

  • Show full URI/URL in Chrome's developer tools Network tab

    - by Lev
    When using Chrome to debug, I find it incredibly difficult to be efficient due to the fact that I don't see how I can force the "Network" tab of the developer tools to show the full request URI. It will show the full URI if you hover the link and wait a second, but this is incredibly counterproductive. All of my AJAX requests are sent to ajax.php, and handled by using query string arguments, like: ajax.php?do=profile-set ajax.php?do=game-save ... etc. Since I use AJAX extensively, my network tab is filled with "ajax.php", but I have to manually hover each and every entry to find the request I am looking for. Surely there has got to be another way!? I am constantly fed up by something new in Firefox and immediately force myself back into Chrome, but it is always the developer tools in Chrome that keep me from using it for an extended period of time. Hopefully I can find out how to do this so I can continue using Chrome as my numero uno. I've provided a screen shot to show you where I mean:

So in OnStateChange method, I am checking for document load. I have used STATE_STOP & STATE_IS_DOCUMENT for it. I want to determine which tab window has been associated with particular document request. I have valid DOM Document pointer got from nsIWebProgress *aWebProgress which is 1st input parameter of OnStateChange. if ((aStateFlags & STATE_STOP) && (aStateFlags & STATE_IS_DOCUMENT)) { nsCOMPtr<nsIDOMWindow> domwin; nsCOMPtr<nsIDOMDocument> domDoc; aWebProgress->GetDOMWindow(getter_AddRefs(domwin)); domwin->GetDocument(getter_AddRefs(domDoc)); } I have tried to get nsIDOMDocumentXBL pointer by QIing nsIDOMDocument pointer(domDoc in my example) but it fails with Error code 0x80004002 (2147500034) i.e.NS_ERROR_NO_INTERFACE.

  • Launch User Control in a tab control dynamically

    - by Redburn
    I have a custom built menu system in which I would like to load user controls from another project into a tab control on my main project (menu control) User control Project : foobar Menu system Project : Menu The function to load them into the tab control: private void LaunchWPFApplication(string header, string pPath) { // Header - What loads in the tabs header portion. // pPath - Page where to send the user //Create a new browser tab object BrowserTab bt = tabMain.SelectedItem as BrowserTab; bt = new BrowserTab(); bt.txtHeader.Text = header; bt.myParent = BrowserTabs; //Load in the path try { Type formType = Type.GetType(pPath, true); bt.Content = (UserControl)Activator.CreateInstance(formType); } catch { MessageBox.Show("The specified user control : " + pPath + " cannot be found"); } //Add the browser tab and then focus BrowserTabs.Add(bt); bt.IsSelected = true; } And what I send to the function as an example: LaunchWPFApplication("Calculater", "foobar.AppCalculater"); But every time run, the application complains that the formType is null. I am confused on how to load the user control and curious if I'm sending the correct parameters.

  • SWT: scrollable area within a tab

    - by DaveJohnston
    I am trying to add a scrollable area to my tabbed window. So far I have a CTabFolder in a shell. I have added 5 CTabItems to it and everything works as expected. On one of my CTabItems the contents are too big to fit on the screen so I would like to be able to scroll. The contents is a collection of Groups each containing various widgets. So the CTabFolder is created as follows: CTabFolder tabs = new CTabFolder(shell, SWT.BORDER); tabs.setSimple(false); tabs.setUnselectedImageVisible(false); tabs.setUnselectedCloseVisible(false); tabs.setMinimizeVisible(false); tabs.setMaximizeVisible(false); FormData tabsLayoutData = new FormData(); tabsLayoutData.top = new FormAttachment(0, 5); tabsLayoutData.left = new FormAttachment(0, 5); tabsLayoutData.bottom = new FormAttachment(92, 0); tabsLayoutData.right = new FormAttachment(100, -5); tabs.setLayoutData(tabsLayoutData); Then the CTabItem: CTabItem tab = new CTabItem(tabs, SWT.NONE); tab.setText("Role"); Then the contents: Composite tabArea = new Composite(tabs, SWT.V_SCROLL); tabArea.setLayout(new FormLayout()); tab.setControl(tabArea); So the groups contained within the tab are created with tabArea as the parent and everything appears as you would expect. The problem is though that the vertical scroll bar is always present but doesn't seem to do anything. The contents are chopped off at the bottom of the tabArea composite. Is there anything else I need to do to get the scrolling to work properly?

  • Updating Android Tab Icons

    - by lnediger
    I have an activity which has a TabHost containing a set of TabSpecs each with a listview containing the items to be displayed by the tab. When each TabSpec is created, I set an icon to be displayed in the tab header. The TabSpecs are created in this way within a setupTabs() method which loops to create the appropriate number of tabs: TabSpec ts = mTabs.newTabSpec("tab"); ts.setIndicator("TabTitle", iconResource); ts.setContent(new TabHost.TabContentFactory( { public View createTabContent(String tag) { ... } }); mTabs.addTab(ts); There are a couple instances where I want to be able to change the icon which is displayed in each tab during the execution of my program. Currently I am deleting all the tabs, and calling the above code again to re-create them. mTabs.getTabWidget().removeAllViews(); mTabs.clearAllTabs(true); setupTabs(); Is there a way to replace the icon that is being displayed without deleting and re-creating all of the tabs?
