  • What exactly is the Nullify delete rule doing?

    - by dontWatchMyProfile
    Does that mean that if I delete an managed object which has references (relationship) to some others, the relationships are removed to those others? Example: objectA references objectB and objectC. objectA gets deleted, it's relationship to objectB and objectC is set to the Nullify rule. What happens in detail?

  • Where do Client-only rules execute on a single profile with multiple Outlooks open?

    - by Roger
    I have two outlooks 2007 open on two different machines logged in to the same account. The issue is I have is with client-only rules for sound alerts executing intermittently. All other rules work correctly, because they are run on the Exchange Server, but the client-only ones seem to pick and choose when to produce sounds. Is there something I can do to make my client-only rules run reliably on one particular instance of outlook?

  • How to calculate an angle from three points?

    - by HelloMoon
    Lets say you have this: P1 = (x=2, y=50) P2 = (x=9, y=40) P3 = (x=5, y=20) Assume that P1 is the center point of a circle. It is always the same. I want the angle that is made up by P2 and P3, or in other words the angle that is next to P1. The inner angle to be precise. It will be always a sharp angle, so less than -90 degrees. I thought: Man, that's simplest geometry maths. But I looked for a formula for like 6 hours now and people talk about most complicated NASA stuff like arcos and vector scalar product stuff. My head feels like in a fridge. Some math gurus here that think this is a simple problem? I think the programing language doesn't matter here but for those who think it does: java and objective-c. need that for both. haven't tagged it for these, though.

  • how to 'scale' these three tables?

    - by iddqd
    I have the following Tables: Players id playerName Weapons id type otherData Weapons2Player id playersID_reference weaponsID_reference That was nice and simple. Now I need to SELECT items from the Weapons table, according to some of their characteristics that i previously just packed into the otherData column (since it was only needed on the client side). The problem is, that the types have varying characteristics - but also a lot of similar data. So I'm trying to decide on the following possibilities, all of which have their pros and cons. Solution A Kill the Weapons table, and create a new table for each Weapon-Type: Weapons_Swords id bladeType damage otherData Weapons_Guns id accuracy damage ammoType otherData But how will i Link these to the Players ? create Weapons_Swords2Players, Weapons_Guns2Players for each weapon-type? (Will result in a lot more JOINS when loading the player with all his weapons...and it's also more complicated to insert a new player) or add another column to Weapons2Players called WeaponsTypeTable, then do sub-selects to the correct Weapons sub-table (seems easier, but not really right, slightly easier insert i guess) Solution B Keep the Weapons table, and add all the fields i need to it. The Problem is that then there will be NULL fields, since not all Weapon-Types use all fields (can't be right) Weapons id type accuracy damage ammoType bladeType otherData This seems to be pretty basic stuff, but i just can't decide what's best. Or is there a correct Solution C? many thanks.

  • Issue while adding 'Cc' Field in 'TTMessageController' (Three 20)

    - by Deepika
    Hi All I am using the TTMessageController class for compose mail.There is only 'To' recepients Field in this class. I added the Cc Field in it. I have used this code: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { _fields = [[NSArray alloc] initWithObjects: [[[TTMessageRecipientField alloc] initWithTitle: TTLocalizedString(@"To:", @"") required: YES] autorelease], [[[TTMessageRecipientField alloc] initWithTitle: TTLocalizedString(@"Cc:", @"") required: YES] autorelease], [[[TTMessageSubjectField alloc] initWithTitle: TTLocalizedString(@"Subject:", @"") required: NO] autorelease], nil]; self.title = TTLocalizedString(@"New Message", @""); self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle: TTLocalizedString(@"Cancel", @"") style: UIBarButtonItemStyleBordered target: self action: @selector(cancel)] autorelease]; self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle: TTLocalizedString(@"Send", @"") style: UIBarButtonItemStyleDone target: self action: @selector(send)] autorelease]; self.navigationItem.rightBarButtonItem.enabled = NO; } return self; } When I type anything in 'To' or 'Cc' field , two lists are appearing as search result:- One for 'To' field and second for 'Cc' Field. I want to show only one list according to 'To' or 'Cc' Field. Please suggest me any idea how can I resolve it or some other better way to implement my requirements? Thanks Deepika

  • Three State Treeview Windows Forms

    - by alhambraeidos
    Hello everybody people, One of the frustrations with the standard TreeView is that you can't show a partial selection to indicate that some of the children are selected. A partial selection in a complex tree allows the user to easily determine where the selections are, even if the tree is not completely expanded. A similar idea is used in manu backup programs to allow the user to select the files to be backed up. Does anyone know of a way to make the checks in a treeview checkbox gray? I want to gray the check of a parent node when some (but not all) of its child nodes are checked. Kinda like what you see when you are selecting options to install during a software installation. I have seen several post, but is older (2000, 2007 year). I now, in 2010, the better answer possible is required. I use VS 2008 . Net 3.5 , Windows Forms Thanks in advanced, greetings

  • Remove pointer object whose reference is mantained in three different lists

    - by brainydexter
    I am not sure how to approach this problem: 'Player' class mantains a list of Bullet* objects: class Player { protected: std::list< Bullet* > m_pBullet_list; } When the player fires a Bullet, it is added to this list. Also, inside the constructor of bullet, a reference of the same object is updated in CollisionMgr, where CollisionMgr also mantains a list of Bullet*. Bullet::Bullet(GameGL*a_pGameGL, Player*a_pPlayer) : GameObject( a_pGameGL ) { m_pPlayer = a_pPlayer; m_pGameGL->GetCollisionMgr()->AddBullet(this); } class CollisionMgr { void AddBullet(Bullet* a_pBullet); protected: std::list< Bullet*> m_BulletPList; } In CollisionMgr.Update(); based on some conditions, I populate class Cell which again contain a list of Bullet*. Finally, certain conditions qualify a Bullet to be deleted. Now, these conditions are tested upon while iterating through a Cell's list. So, if I have to delete the Bullet object, from all these places, how should I do it so that there are no more dangling references to it? std::list< Bullet*>::iterator bullet_it; for( bullet_it = (a_pCell->m_BulletPList).begin(); bullet_it != (a_pCell->m_BulletPList).end(); bullet_it++) { bool l_Bullet_trash = false; Bullet* bullet1 = *bullet_it; // conditions would set this to true if ( l_Bullet_Trash ) // TrashBullet( bullet1 ); continue; } Also, I was reading about list::remove, and it mentions that it calls the destructor of the object we are trying to delete. Given this info, if I delete from one list, the object does not exist, but the list would still contain a reference to it..How do I handle all these problems ? Can someone please help me here ? Thanks PS: If you want me to post more code or provide explanation, please do let me know.

  • Git from localhost to remotehost with a team of three

    - by Mark McDonnell
    Hi, I'm completely new to Git. I've only just worked out how to use Github in a basic way (e.g. push my local file changes to Github - so I've not done 'pulling' down of content from Github and 'merging' it into my localhost version or anything like that). I had a look over at this existing question - Git: localhost remote development remote production - but I think it may have been a bit advanced for me at this stage as I didn't quite understand the terminology that most of the people were using. What I would like to achieve is to have a local server set-up that my team of developers can all 'push' to/'pull' from etc. And then have that local server upload any updated files automatically to our web server so we could see the updates live in the browser. I'm happy to get a server set-up in the office running Mac OSX Server and then installing Git on it and then getting the devs to write a shell script to push to the remote server but only if it was fairly easy for the devs local git to push to this new local server. I'm not a network engineer so I don't know what would need to be set-up for that to work, I know obviously we could set-up the server to be accessible via a local ip address like 192.168.0.xxx but not sure how that works with pushing to a git repository on that server? Would that literally be something like doing this on my local machine: git remote add MyGitFile git://192.168.0.xxx/MyGitFile.git ? Any ideas or advice you can give to a total Git newbie trying to help his team get a better work flow. Kind regards, Mark

  • Filter across three tables using Django

    - by Vanessa MacDougal
    I have 3 django models, where the first has a foreign key to the second, and the second has a foreign key to the third. Like this: class Book(models.Model): year_published = models.IntField() author = models.ForeignKey(Author) class Author(models.Model): author_id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) agent = models.ForeignKey(LitAgent) class LitAgent(models.Model): agent_id = models.AutoField(primary_key=True) name = models.CharField(max_length=50) I want to ask for all the literary agents whose authors had books published in 2006, for example. How can I do this in Django? I have looked at the documentation about filters and QuerySets, and don't see an obvious way. Thanks.

  • Using a join with three tables when a field might be null

    - by John
    Hello, The code below works great. It combines data from two MySQL tables. I would like to modify it by pulling in some data from a third MySQL table called "comment." In the HTML table below, "title" is a field in the MySQL table "submission." Every "title" has a corresponding "submissionid" field. The field "submissionid" is also found in the "comment" MySQL table. In the HTML table below, I would like "countComments" to equal the number of times a field called "commentid" appears in the MySQL table "comment" for any given "submissionid," where the "submissionid" is the same in both the "submission" and "comment" tables, and where the "submissionid" corresponds to the "title" being used. Here's the catch: if there is no row in the MySQL table "comment" that corresponds with the "submissionid" being used for "table", I would like "countComments" to equal to zero. How can I do this? Thanks in advance, John $sqlStr = "SELECT s.loginid, s.title, s.url, s.displayurl, l.username FROM submission AS s, login AS l WHERE s.loginid = l.loginid ORDER BY s.datesubmitted DESC LIMIT 10"; $result = mysql_query($sqlStr); $arr = array(); echo "<table class=\"samplesrec\">"; while ($row = mysql_fetch_array($result)) { echo '<tr>'; echo '<td class="sitename1"><a href="http://www.'.$row["url"].'">'.$row["title"].'</a></td>'; echo '</tr>'; echo '<tr>'; echo '<td class="sitename2"><a href="http://www...com/sandbox/members/index.php?profile='.$row["username"].'">'.$row["username"].'</a><a href="http://www...com/sandbox/comments/index.php?submission='.$row["title"].'">'.$row["countComments"].'</a></td>'; echo '</tr>'; } echo "</table>";

  • Truncate text if it atempts to run into three lines

    - by Jigs
    I have a small about 140px wide aligned next to a picture. In total there is space for four lines of text. The first two lines are reserved for the title and there are two lines of other info. I want the title to be cut if it spans more than two lines else it will push the other info out of line with the bottom of the image. The only solution I could think of was to create a div the height of two lines with an overflow to hidden. However, if the title is only one line it leaves a big gap. The solution can be Jquery, plain javascript, CSS or even PHP (if its possible). TIA
