  • MySQL default value based on view

    - by Jake
    Basically I have a bunch of views based on a simple discriminator column (eg. CREATE VIEW tablename AS SELECT * FROM tablename WHERE discrcolumn = "discriminator value"). Upon inserting a new row into this view, it should insert "discriminator value" into discrcolumn. I tried this, but apparently MySQL doesn't figure this out itself, as it throws an error "Field of view viewname underlying table does not have a default value". The discriminator column is set to NOT NULL of course. How do I mend this? Perhaps a pre-insert trigger? UPDATE: Triggers won't work on views, see below comment. Would it work to create a trigger on the table which uses a variable, and set that variable at establishing the connection? For each connection the value of that variable would be the same, but it could differ from other connections. EDIT: This appears to work... Setup: CREATE TRIGGER insert_[tablename] BEFORE INSERT ON [tablename] FOR EACH ROW SET NEW.[discrcolumn] = @variable Runtime: SET @variable = [descrvalue]; INSERT INTO [viewname] ([columnlist]) VALUES ([values]);

  • access JRUN jndi environment vaiables from coldfusion (java)

    - by jake
    I want to put some instance specific configuration information in JNDI. I looked at the information here: http://www.adobe.com/support/jrun/working_jrun/jrun4_jndi_and_j2ee_enc/jrun4_jndi_and_j2ee_enc03.html I have added this node to the web.xml: <env-entry> <description>Administrator e-mail address</description> <env-entry-name>adminemail</env-entry-name> <env-entry-value>[email protected]</env-entry-value> <env-entry-type>java.lang.String</env-entry-type> </env-entry> In coldfusion I have tried several different approaches to querying the data: <cfset ctx = createobject("java","javax.naming.InitialContext") > <cfset val = ctx.lookup("java:comp/env") > That lookup returns a jrun.naming.JRunNamingContext. If i preform a lookup on ctx for the specific binding I am adding I get an error. <cfset val = ctx.lookup("java:comp/env/adminemail") > No such binding: adminemail Preforming a listBindings returns an empty jrun.naming.JRunNamingEnumeration. <cfset val = ctx.listBindings("java:comp/env") > I only want to put a string value (probably several) into the ENC (or any JNDI directory at this point).

  • Is naming a software product the same as a book legally problematic?

    - by Jake Petroules
    I came up with a name for a software product I'm developing. It's composed of two common English words put together (for example, Firefox, Silverlight, etc.). I Googled the name to see if it was being used by any other software product before committing to it. After finding none, I did notice that there is a book published around 60 years ago, by that same name. Would it be legally problematic to name my software product as such, or does it being a software product vs a book make it irrelevant? PS - I know this isn't really a programming question, but naming is related to software development, isn't it? ;) PPS - How do companies like Microsoft get away with naming things "Windows" and "Office"? Or are they just legally called "Microsoft Windows" and "Microsoft Office"? Do developer names always precede software product names? Would naming a software product "Jones Office" be illegal?

  • Java. Best procedure to de-serialize a Java generic object?

    - by Jake
    What is the best procedure for storing and retrieving, using native Java serialization, generic objects like ArrayList<String>? Edit: To clarify. When I serialize an object of type ArrayList<String> I'd like to de-serialize to the same type of object. However, I know of no way to cast back to this generic object without causing warnings.

  • How do I do arithmetic operations on HH:MM:SS format time strings in C#?

    - by Jake
    I have a series of times that are coming to me as strings from a web service. The times are formated as HH:MM:SS:000 (3 milisecond digits). I need to compare two times to determine if one is more than twice as long as the other: if ( timeA / timeB > 2 ) What's the simplest way to work with the time strings? If I was writing in Python this would be the answer to my question: Difference between two time intervals in Python

  • Is there a good way to copy a Gtk widget?

    - by Jake
    Is there a way, using the Gtk library in C, to clone a Gtk button (for instance), and pack it somewhere else in the app. I know you can't pack the same widget twice. And that this code obviously wouldn't work, but shows what happens when I attempt a shallow copy of the button: GtkButton *a = g_object_new(GTK_TYPE_BUTTON, "label", "o_0", NULL); GtkButton *b = g_memdup(b, sizeof *b); gtk_box_pack_start_defaults(GTK_BOX(vbox), GTK_WIDGET(b)); There is surrounding code which creates a vbox and packs it in a window and runs gtk_main(). This will result in these hard to understand error messages: (main:6044): Gtk-CRITICAL **: gtk_widget_hide: assertion `GTK_IS_WIDGET (widget)' failed (main:6044): Gtk-CRITICAL **: gtk_widget_realize: assertion `GTK_WIDGET_ANCHORED (widget) || GTK_IS_INVISIBLE (widget)' failed ** Gtk:ERROR:/build/buildd/gtk+2.0-2.18.3/gtk/gtkwidget.c:8431:gtk_widget_real_map: assertion failed: (GTK_WIDGET_REALIZED (widget)) Along the same lines, if I were to write my own GObject (not necessarily a Gtk widget), is there a good way to write a copy constructor. Im thinking it should be an interface with optional hooks and based mostly on the properties, handling the class's hierarchy in some way. I'd want to do this: GtkButton *b = copyable_copy(COPYABLE(a)); If GtkButton could use a theoretical copyable interface.

  • Java: Finding objects in collections.

    - by Jake
    This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth. A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?

  • How to set input focus to a shown dialog in Qt?

    - by Jake Petroules
    In a button click slot, I create and exec() a dialog with a NULL parent. Inside the dialog's constructor, I have: this->activateWindow(); this->raise(); this->setFocus(); The dialog is application modal and has strong focus. However, it does NOT respond to keyboard events until I click on it. How do I make the dialog get focus without having to click it?

  • Copy and Store LPTSTR in class causes crash

    - by Jake M
    I am attempting to copy a LPTSTR and store that string as a member variable in an object. But my attempts to copy the LPTSTR seem to fail and when I go to access/print the value of the copied LPTSTR I get a program crash. Is it possible to copy a LPTSTR and store it in my class below or is it better to just use a TCHAR*? class Checkbox { private: LPTSTR text; HWND hwnd; public: Checkbox(HWND nHwnd, LPTSTR nText) { lstrcpy(checkText, text); } void print() { // Causes a crash MessageBox(hwnd, text, text, MB_OK); } };

  • C# Combobox and TabControl woes

    - by Jake
    enter code hereI have a TabControl on a Form and in the TabPages there are ComboBoxes. When the form OnLoad, I populate the ListItems in the ComboBoxes and the attempt to set default values to string.Empty. However, the ComboBox.SelectedText = string.Empty only works for the first TabPage. The other ComboBoxes ignore the command and take the default value as the first item in the list. Why is this so? How can I overcome it? The ComboBoxes are all set up by this function public static void PrepareComboBox(ComboBox combobox, FieldValueList list) { combobox.DropDownStyle = ComboBoxStyle.DropDown; combobox.AutoCompleteSource = AutoCompleteSource.ListItems; combobox.AutoCompleteMode = AutoCompleteMode.Suggest; combobox.DataSource = list.DataSource; combobox.DisplayMember = list.DisplayMember; combobox.ValueMember = list.ValueMember; combobox.Text = string.Empty; combobox.SelectedText = string.Empty; }

  • Threadsafe way of exposing keySet()

    - by Jake
    This must be a fairly common occurrence where I have a map and wish to thread-safely expose its key set: public MyClass { Map<String,String> map = // ... public final Set<String> keys() { // returns key set } } Now, if my "map" is not thread-safe, this is not safe: public final Set<String> keys() { return map.keySet(); } And neither is: public final Set<String> keys() { return Collections.unmodifiableSet(map.keySet()); } So I need to create a copy, such as: public final Set<String> keys() { return new HashSet(map.keySet()); } However, this doesn't seem safe either because that constructor traverses the elements of the parameter and add()s them. So while this copying is going on, a ConcurrentModificationException can happen. So then: public final Set<String> keys() { synchronized(map) { return new HashSet(map.keySet()); } } seems like the solution. Does this look right?

  • Mercurial Workflow (Shared Files)

    - by Jake Pearson
    Let's say I have programmers and artists working on a project. The artists have some folders they care about: /Doodles /Images/Jpgs And maybe the programmers have a folder like this: /Code/View/Jpgs What is the best process in Mercurial to keep the 2 Jpgs folders synced? I have used Vault, where you can have 2 or more files/folders linked in a repository so updating one updates another. Is there a way to do the same thing with Mercurial?

  • Django many-to-many relationship to self with extra data, how do I select from a certain direction?

    - by Jake
    I have some hierarchical data where each Set can have many members and can belong to more than one Set(group) Here are the models: class Set(models.Model): ... groups = models.ManyToManyField('self', through='Membership', symmetrical=False) members = models.ManyToManyField('self', through='Membership', symmetrical=False) class Membership(models.Model): group = models.ForeignKey( Set, related_name='Members' ) member = models.ForeignKey( Set, related_name='Groups' ) order = models.IntegerField( default=-1 ) I want to know how to get all the members or all the groups for a Set instance. I think I can do it as follows, but it's not very logical, can anyone tell me what's going on and how I should be doing it? # This gives me a set of Sets # Which seems to be the groups this Set belongs to set_instance.set_set.all() # These give me a set of Memberships, not Sets set_instance.Members.all() set_instance.Groups.all() # These they both return a set of Sets # which seem to be the members of this one set_instance.members.all() set_instance.groups.all()

  • setting codeigniter mysql datetime column to time() always sets it to 0

    - by Jake
    Hi guys. I'm using Codeigniter for a small project, and my model works correctly except for the dates. I have a column defined: created_at datetime not null and my model code includes in its array passed into db-insert: 'created_at' = time() This produces a datetime value of 0000-00-00 00:00:00. When I change it to: 'created_at' = "from_unixtime(" . time() . ")" it still produces the 0 datetime value. What am I doing wrong? How can I set this field to the given unix time? Also, I know mysql sets TIMESTAMP columns automatically for you - I'm not interested in that solution here. So far I can't find a complete example of this on the web.

  • Getting the ranking of a photo in SQL

    - by Jake Petroules
    I have the following tables: Photos [ PhotoID, CategoryID, ... ] PK [ PhotoID ] Categories [ CategoryID, ... ] PK [ CategoryID ] Votes [ PhotoID, UserID, ... ] PK [ PhotoID, UserID ] A photo belongs to one category. A category may contain many photos. A user may vote once on any photo. A photo can be voted for by many users. I want to select the ranks of a photo (by counting how many votes it has) both overall and within the scope of the category that photo belongs to. The count of SELECT * FROM Votes WHERE PhotoID = @PhotoID being the number of votes a photo has. I want the resulting table to have generated columns for overall rank, and rank within category, so that I may order the results by either. So for example, the resulting table from the query should look like: PhotoID VoteCount RankOverall RankInCategory 1 48 1 7 3 45 2 5 19 33 3 1 2 17 4 3 7 9 5 5 ... ...you get the idea. How can I achieve this? So far I've got the following query to retrieve the vote counts, but I need to generate the ranks as well: SELECT PhotoID, UserID, CategoryID, DateUploaded, (SELECT COUNT(CommentID) AS Expr1 FROM dbo.Comments WHERE (PhotoID = dbo.Photos.PhotoID)) AS CommentCount, (SELECT COUNT(PhotoID) AS Expr1 FROM dbo.PhotoVotes WHERE (PhotoID = dbo.Photos.PhotoID)) AS VoteCount, Comments FROM dbo.Photos

  • jQuery sliding animation not working

    - by Jake Zeitz
    I have three divs stacked on each other but offset so that a part of each div is visible. When one of the bottom divs is clicked I want the top div to animate out and back into the stack at the bottom, then the div that is clicked will appear at the top. So far I only have the code for when the middle div is clicked, but I cannot get it to work properly. What am I doing wrong? (I also realize that the code I wrote is probably terrible, this is the first jQuery code I have written.) The css is very very simple: .first { z-index: 3; } .second { z-index: 2; } .third { z-index: 1; } The basic html is this: <div class="first"></div> <div class="second"></div> <div class="third"></div> Here is my code: $("div.second").click(function () { $("div.first").animate({ left: "-=200px"}, {duration: "fast", complete: function () { $("div.first").removeClass("first").addClass("third").animate({left: "+=350px", top: "+=60px"}, "fast"); } }); $("div.second").animate({ left: "-=24px", top: "-=30px"}, {duration: "fast", complete: function () { $("div.second").removeClass("second").addClass("first"); } }); $("div.third").animate({ left: "-=24px", top: "-=30px"}, {duration: "fast", complete: function () { $("div.third").removeClass("third").addClass("second"); } }); }); I can get the div.first to move to the side and back. But now I can't get the classes to stay changed. What keeps happening is the div.second will remove it's class and add .first in the animation, but when the animation is complete, it acts like it still has a class of .second.

  • VirtualHost problem with passenger (mod_rails)

    - by Jake
    Hi all, I'm at my wit's end here with virtual hosting. I'm trying to install redmine and it works with the webrick test server, but when I tried to use passenger (mod_rails) to host and go to the address I specified when in the virtualhost part of my apache config file nothing happens. Here is the relavent section of /etc/httpd/conf/httpd.conf where I try to set up the virtual host: <VirtualHost *:80> SetEnv RAILS_ENV production ServerName redmine.MYSITE.com:80 DocumentRoot /opt/redmine-1.0.5/public/ <Directory /opt/redmine-1.0.5/public/> Options -MultiViews Allow from all AllowOverride none </Directory> However, when I got to redmine.MYSITE.com:80 nothing happens, I just get our normal home page. I have no idea what the problem is, any help our guidance would be greatly appreciated. If you need any other information, please tell me and I'll provide it.

  • Where is shared_ptr?

    - by Jake
    I am so frustrated right now after several hours trying to find where shared_ptr is located. None of the examples I see show complete code to include the headers for shared_ptr (and working). Simply stating "std" "tr1" and "" is not helping at all! I have downloaded boosts and all but still it doesn't show up! Can someone help me by telling exactly where to find it? Thanks for letting me vent my frustrations!

  • How can I make my tableview enter editing mode?

    - by Jake
    Hi, for some reason I can't get my tableview to enter editing mode. It's a little harder than it might seem because I'm using some open source code to make a calendar (iCal esque) with a tableview under it, and it's not quite as straightforward as just using a regular tableview. Basically, I have two classes. One (let's say Class A) is a UIViewController and the other (Class B) is that viewController's datasource and tableview delegate. In Class B, I've implemented -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath; which works fine, but if I put an edit nav bar item in Class A (the view controller), nothing happens. Am I forgetting certain protocols, or certain special methods that I need to write? Thanks for any help, and apologies if I'm missing something, I'm just learning to work with other people's code.
