  • Custom Folders in SSMS Object Explorer? Yes, we can!

    - by Luca Zavarella
    When you have a huge objects’ number in SSMS Object Explorer, you often get lost in finding items. So it’d be useful to catalog those objects in folders, in order to follow an application’s logical layer subdivision, for example. There is a fantastic add-in for SSMS that helps us to do that: http://www.sqltreeo.com The developer of this add-in has written a related post in his blog: http://www.sqltreeo.com/wp/dowload-free-ssms-add-in-to-create-own-folder-for-database-objects/ So another useful tool to add to our  SQL Server toolbox

  • How to allow sorting in the Django admin by a custom list_display field, which doesn't have a DB fie

    - by Gj
    I have a custom list_display field which is responsible for a column of integers in one of my admin pages. I need to allow staff members to sort according to it. There's a solution for how to acheive that if the integer represents a count/average/etc of some DB field, which is not the case for me. [ the solution for that case is here: http://stackoverflow.com/questions/2168475/django-admin-how-to-sort-by-one-of-the-custom-list-display-fields-that-has-no-da ] Any ideas how I can achieve this sorting without actually creating and maintaining a DB field for the values?

  • How does one control select lists using form API ?

    - by user363036
    I know this is somewhat of a newb question but I am running into a deadline and 3 days of Drupal experience will just not cut it... $form['gender'] = array('#type' = 'select', '#title' = t('Gender: *'), '#options' = array(t('Male'), t('Female')), '#required' = TRUE, '#weight' = 2, ); How do I assign values to select values ? For example Male - 'm' and Female- 'f'. Also how do I give the select box a default caption "please select gender..." Thanks guys

  • How can I define custom keyboard mappings to resize, move, and manage windows?

    - by fumon
    I just returned to ubuntu (13.04) after a year using OS X exclusively. I love the improvements that have come to ubuntu and unity, and I'm glad to be back. There's just one thing, though... Slate is a simple OS X tool that allows users to quickly create powerful keyboard macros and really take advantage of their screen space. I have to say I was spoiled by it. Even on a tiny laptop, my workflow was never interrupted by changing workspaces or leaving the keyboard to adjust a window, because perfect adjustment was a keystroke or two away. For example: bind h:ctrl;alt;cmd resize -10% +0 # this increases the window's left width by 10% bind h:shift;alt nudge -10% +0 # this moves the window left by 10% You make a big config file, and like vim, tmux, and everything else, it just becomes muscle memory. I can't seem to find a way to achieve anything close to this in linux or ubuntu. I've tried to make do with compiz window settings and the built-in stuff Ubuntu offers, but it's not even in the same realm. Although to be fair, this level of tuning isn't something most people care about. Thanks, guys. :) Any feedback would be appreciated.

  • Custom HTML Tags: Are there any specifications stating a standard way to handle them?

    - by blesh
    It seems like for years they've just been given default styling and inline display. Is there a spec somewhere that has dictated this? I've looked over the RFC's but I'm not particularly good with RFC-ese, and I didn't notice anything anywhere. For example <body> Some content <mycustomtag>something else</mycustomtag> more content. </body> I can still style it with CSS, and the browser doesn't outright vomit... so it seems like there is some sort of expected behavior. Was that dictated by a specification?

  • How do I programmatically add an Android Gestures view to a custom view?

    - by user351201
    I have a custom view that works fine and I'm trying to get gestures into it. The most common technique I see is to add XML, such as this (from Android docs: My view is within a RelativeView and when I attempt to reference this GetureOverlayView, I get an exception. I've also tried to connect within my existing custom view class, like this: mGestures = new GestureOverlayView(context, attrs); mGestures.addOnGesturePerformedListener(this); But the callback is never invoked. Can someone see my errors or suggest a better way that will allow me to get gesture callbacks?

  • How do I handle editing of custom types in a C# datagridview?

    - by Ian Hopkinson
    I have a datagridview in which one column contains a custom class, which I have set using: dgvPeriods.Columns[1].ValueType = typeof(ExDateTime); It is rigged up to display correctly by handling the CellFormatting event, but I'm unsure what event to handle for cell editing. In the absence of doing anything I get a FormatException as the datagridview tries to convert String to ExDateTime as I try to move focus out of the edited cell. I tried adding type conversion to my ExDateTime custom class: public static implicit operator ExDateTime(string b) { return new ExDateTime(b); } But this this didn't work. I also tried handling the DataError event, but this seems to fire too late. The datagridview is not databound.

  • Does Python Django support custom SQL and denormalized databases with no Foreign Key relationships?

    - by Jay
    I've just started learning Python Django and have a lot of experience building high traffic websites using PHP and MySQL. What worries me so far is Python's overly optimistic approach that you will never need to write custom SQL and that it automatically creates all these Foreign Key relationships in your database. The one thing I've learned in the last few years of building Chess.com is that its impossible to NOT write custom SQL when you're dealing with something like MySQL that frequently needs to be told what indexes it should use (or avoid), and that Foreign Keys are a death sentence. Percona's strongest recommendation was for us to remove all FKs for optimal performance. Is there a way in Django to do this in the models file? create relationships without creating actual DB FKs? Or is there a way to start at the database level, design/create my database, and then have Django reverse engineer the models file?

  • Modified map2 (without truncation of lists) in F# - how to do it idiomatically?

    - by Maciej Piechotka
    I'd like to rewrite such function into F#: zipWith' :: (a -> b -> c) -> (a -> c) -> (b -> c) -> [a] -> [b] -> [c] zipWith' _ _ h [] bs = h `map` bs zipWith' _ g _ as [] = g `map` as zipWith' f g h (a:as) (b:bs) = f a b:zipWith f g h as bs My first attempt was: let inline private map2' (xs : seq<'T>) (ys : seq<'U>) (f : 'T -> 'U -> 'S) (g : 'T -> 'S) (h : 'U -> 'S) = let xenum = xs.GetEnumerator() let yenum = ys.GetEnumerator() seq { let rec rest (zenum : IEnumerator<'A>) (i : 'A -> 'S) = seq { yield i(zenum.Current) if zenum.MoveNext() then yield! (rest zenum i) else zenum.Dispose() } let rec merge () = seq { if xenum.MoveNext() then if yenum.MoveNext() then yield (f xenum.Current yenum.Current); yield! (merge ()) else yenum.Dispose(); yield! (rest xenum g) else xenum.Dispose() if yenum.MoveNext() then yield! (rest yenum h) else yenum.Dispose() } yield! (merge ()) } However it can hardly be considered idiomatic. I heard about LazyList but I cannot find it anywhere.

  • How do I change the list using mutable lists in Racket or Scheme?

    - by exOne
    I need your help Can anyone help me? first question This procedure should modify each element which’s index in the list is even. The value of the element should be equal to the new-element. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-indices number-list 10) The new list: 1 10 8 10 43 10 78 second question This problem is the extended version of Question 1. (modify-even-odd-indices my-list new-element modification-type) This procedure should modify each element according to the modification-type. The modification-type can be even or odd. For example: (define number-list (1 56 8 1 43 9 78)) (modify-even-odd-indices number-list 10 ‘even’) The new list: 1 10 8 10 43 10 78 (modify-even-odd-indices number-list 10 ‘odd’) The new list: 10 56 10 1 10 9 10

  • Showing custom model validation exceptions in the Django admin site.

    - by Guy Bowden
    I have a booking model that needs to check if the item being booked out is available. I would like to have the logic behind figuring out if the item is available centralised so that no matter where I save the instance this code validates that it can be saved. At the moment I have this code in a custom save function of my model class: def save(self): if self.is_available(): # my custom check availability function super(MyObj, self).save() else: # this is the bit I'm stuck with.. raise forms.ValidationError('Item already booked for those dates') This works fine - the error is raised if the item is unavailable, and my item is not saved. I can capture the exception from my front end form code, but what about the Django admin site? How can I get my exception to be displayed like any other validation error in the admin site?

  • Wordpress auto-generated "canonical" link - get them to use a custom URL parameter?

    - by kiko
    Hello - Does anyone know how to modify the Wordpress canonical links to add a custom URL parameter? I have a Wordpress site with a page that queries a separate (non-Wordpress) database. I passed the URL parameter "pubID" to display individual books and it is working OK. Example: http://www.uglyducklingpresse.org/catalog/browse/item/?pubID=63 But the individual books are not showing up properly in Google - the ?pubID parameter is stripped out. I think maybe this is because all the item pages have the same auto-generated "canonical" URL link tag in the source - one with the "pubID" parameter stripped out. Example: link rel='canonical' href='http://www.uglyducklingpresse.org/catalog/browse/item/' Is there a way to perhaps edit .htaccess to add a custom URL parameter to Wordpress, so that the parameter is not stripped out by permalinks and the "canonical" links? Or maybe there's another solution ... Thank you for any ideas!

  • C++ linked list based tree structure. Sanely move nodes between lists.

    - by krunk
    The requirements: Each Node in the list must contain a reference to its previous sibling Each Node in the list must contain a reference to its next sibling Each Node may have a list of child nodes Each child Node must have a reference to its parent node Basically what we have is a tree structure of arbitrary depth and length. Something like: -root(NULL) --Node1 ----ChildNode1 ------ChildOfChild --------AnotherChild ----ChildNode2 --Node2 ----ChildNode1 ------ChildOfChild ----ChildNode2 ------ChildOfChild --Node3 ----ChildNode1 ----ChildNode2 Given any individual node, you need to be able to either traverse its siblings. the children, or up the tree to the root node. A Node ends up looking something like this: class Node { Node* previoius; Node* next; Node* child; Node* parent; } I have a container class that stores these and provides STL iterators. It performs your typical linked list accessors. So insertAfter looks like: void insertAfter(Node* after, Node* newNode) { Node* next = after->next; after->next = newNode; newNode->previous = after; next->previous = newNode; newNode->next = next; newNode->parent = after->parent; } That's the setup, now for the question. How would one move a node (and its children etc) to another list without leaving the previous list dangling? For example, if Node* myNode exists in ListOne and I want to append it to listTwo. Using pointers, listOne is left with a hole in its list since the next and previous pointers are changed. One solution is pass by value of the appended Node. So our insertAfter method would become: void insertAfter(Node* after, Node newNode); This seems like an awkward syntax. Another option is doing the copying internally, so you'd have: void insertAfter(Node* after, const Node* newNode) { Node *new_node = new Node(*newNode); Node* next = after->next; after->next = new_node; new_node->previous = after; next->previous = new_node; new_node->next = next; new_node->parent = after->parent; } Finally, you might create a moveNode method for moving and prevent raw insertion or appending of a node that already has been assigned siblings and parents. // default pointer value is 0 in constructor and a operator bool(..) // is defined for the Node bool isInList(const Node* node) const { return (node->previous || node->next || node->parent); } // then in insertAfter and friends if(isInList(newNode) // throw some error and bail I thought I'd toss this out there and see what folks came up with.

  • How do I set a custom resolution in 12.04 with a nVidia video card (9600 GSO)?

    - by Aaron Agarunov
    I have 32 bit 12.04 and my video card drivers are up to date at "304.64" yet my resolution appears capped at 1920x1080. I am trying to get the resolution to 2560x1440 or even higher, as I am running this machine on a 42" LCD through HDMI and the 1920x1080 resolution will not stretch to fit the screen and is therefore fairly zoomed in. The 9600 GSO supports up to 2560x1600, so this should be no problem for the card itself. I have tried using xrandr, which successfully creates the 2560x1440 60 hertz mode but does not allow me to --addmode or --output it in. I have tried working with the xorg.conf, but I actually can not find a way to create the file since when I try to, I am given an error message stating that the # of monitors I have does not match the # of screens I have. Can anyone provide some help or insight?

  • Removing items from lists and all references to them.

    - by LiamV
    I'm facing a situation where I have dependent objects and I would like to be able to remove an object and all references to it. Say I have an object structure like the code below, with a Branch type which references two Nodes. public class Node { // Has Some Data! } public class Branch { // Contains references to Nodes public Node NodeA public Node NodeB } public class Graph { public List<Node> Nodes; public List<Branch> Branches; } If I remove a Node from the Nodes list in the Graph class, it is still possible that one or more Branch objects still contains a reference to the removed Node, thus retaining it in memory, whereas really what I would quite like would be to set any references to the removed Node to null and let the garbage collection kick in. Other than enumerating through each Branch and checking each Node reference sequentially, are there any smart ideas on how I remove references to the Node in each Branch instance AND indeed any other class which reference the removed Node?

  • Add widgets to custom WordPress sidebars on theme activation?

    - by McGirl
    I'm working on a WordPress 3.0 multi-site installation. Each new blog will use the same theme with slight modifications (a custom Thesis install, if it matters). I'm trying to automate the set-up process for each new blog as much as possible. To that end, I'd like to automatically add widgets to my custom sidebars and widget-enabled footers. It'd be even better if the widgets could have pre-set parameters/content, that I or the blog owner could then go into the Widgets panel and edit. I've searched high and low and haven't been able to figure out a way to make this work. Any and all suggestions are welcome. Thanks so much!

  • Why do i get a 403 error when viewing a Drupal custom menu item via clean url?

    - by Chaulky
    Hi all, I've created a custom menu item in my Drupal 6 website by defining it in a custom module. This is an extremely simple MENU_NORMAL_ITEM menu item. The menu item is defined as /** * Implementation of hook_menu(). */ function menu_test_menu() { $items['menu_test'] = array( 'title' => 'Menu Test', 'page callback' => 'menu_test_hello', 'access callback' => TRUE, 'type' => MENU_NORMAL_ITEM, ); return $items; } Since I have clean URLs on, the path should be www.example.com/menu_test. That URL gives me a 403 error. But, if I enter www.example.com/?q=menu_test, everything works fine. Why am I getting the 403 error? The menu item is useless because it's always trying to go to the clean URL path, which should work but doesn't for some reason. Thanks for the help!

  • Is there a way I can verify my Google Analytics custom report?

    - by SnowboardBruin
    I want to track scrolling on my website since it's a long page (rather than multiple pages). I saw several different methods, with and without an underscore for trackEvent, with and without spaces between commas <script> ... ... ... ga('create', 'UA-45440410-1', 'example.com'); ga('send', 'pageview'); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 100, true]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 75, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 50, false]); _gaq.push([‘_trackEvent’, ‘Consumption’, ‘Article Load’, ‘[URL]’, 25, false]); </script> It takes a day for counts to load with Google Analytics, otherwise I would just tweak and test right now.

  • How to write custom SQLite functions in Javascript inside a Webkit browser?

    - by Jay Godse
    I have just learned how to use the SQLite database for local storage in a Webkit web browser (e.g. Google Chrome or Apple Safari) using the Javascript API. For example the "Sticky Notes" application. However, I know that SQLite has a function called sqlite_create_function() that lets you add custom functions to your instance of SQLite on the fly which can then be used inside SQL queries. This function is described at sqlite.org. I also know that you can call an equivalent of this API in Ruby as described here. QUESTION: Can anybody show me how to do this in Javascript - i.e. write a custom function in Javascript that can be bound into the SQLite database at run time to be called by the SQLite engine, and all inside a Webkit browser?
