  • JSP Iterating over a map of a list when the value might be null

    - by Brian Hoover
    How do I clear the value from the stack of a s:iterator? I'm trying to iterator over a TreeMultimap with a structure like: TreeMultimap<person, lineItems> persons; Using something like: <s:iterator value="attendeesForParticipantTypeEvents.asMap()"> <div> <s:property value="key.name" /><br /> <s:iterator id="currentSku" value="value"> <s:property value="currentSku.name" /><br /> </s:iterator> </div> </s:iterator> This works fine, except when the treeMultimap has null for lineItems, then it's taking the value from the previous iteration. So, a structure like: persons = {{"Person1",["Line1","line2"]}, {"Person2",["Line3","line4"]}, {"Person2",null}} Renders as: <div> Person1<br /> Line1<br /> Line2<br /> </div> <div> Person2<br /> Line3<br /> Line4<br /> </div> <div> Person3<br /> Line3<br /> Line4<br /> </div> Which seems to indicate that the value isn't being cleared on each iterator. What do I need to do to handle the case where value might be null? Thanks for your help

  • Translating this query in LINQ ? (list of like)

    - by Erick
    I would like to translate this query in LINQ ... it is very easy to construct if we do it in pure SQL but in dynamically created LINQ query (building a search query based on user input) it's a whole new story. SELECT * FROM MyTable WHERE 1=1 AND Column2 IN (1,2,3) AND ( Column1 LIKE '%a%' OR Column1 LIKE '%b%' ) Now to try to construct this we tried it this way : if(myOjb.Column2Collection != null) query = query.where(f => f.Column2.Contains(myOjb.Column2Collection)); if(myObj.Column1Collection != null) { // tough part here ? //query = query.Where(); ... } So what would be the best aproach to this normally ? Note that I am aware of the SqlMethod.Like, tho I can't figure a way to implement it here ...

  • C# Design Reduce a Long List of Methods

    - by guazz
    I have a simple application that loads data from an XML file to a database. public class EmployeeLoader() { public void LoadEmpoyees() {...} public void LoadSalaries() {...} public void LoadRegistrationData() {...} public void LoadTaxData() {...} } Is it a good idea to have multiple "Load" methods as this looks like a code smell as I have about tweney Load methods? If so, how do I make my code more readable? Each Load method loads data to the corresponding table in the database via a repository?

  • list all likes to a certain post coming from my friends

    - by Max Favilli
    I know I can get posts (paginated, 25 at times) of a certain user with this: https://graph.facebook.com/575128756/posts And the likes of a certain post (paginated, 25 at times) with this GRAPH api call (I omit the first part of the url): /575128756_176517292390301/likes But if I want to get the likes from friends of the post user only? FQL could be an alternative (from table like and subqueries for friend and stream), but FQL seems so buggy in my tests I don't feel comfortable using it in a productive system. Is there anyway to achieve my target using the GRAPH api?

  • Save list of CGPoints using NSUserDefaults

    - by Chris Daviduik
    I have a bunch of CGPoints from a CCTMXLayer I want to save to NSUserDefaults but cannot seem to figure out an elegant way of doing so. Originally I was hoping to save an NSDictionary with an NSMutableSet for a value containing several NSValues (valueWithCGPoint). From what I can tell neither NSMutableSet or NSValue is supported by NSUserDefaults. At this point I am considering saving the x&y values of the CGPoint as a string and just converting it back and forth as needed.

  • Help: List contents of iPhone application bundle subpath??

    - by bluepill
    Hi, I am trying to get a listing of the directories contained within a subpath of my application bundle. I've done some searching and this is what I have come up with - (void) contents { NSArray *contents = [[NSBundle mainBundle] pathsForResourcesOfType:nil inDirectory:@"DataDir"]; if (contents = nil) { NSLog(@"Failed: path doesn't exist or error!"); } else { NSString *bundlePathName = [[NSBundle mainBundle] bundlePath]; NSString *dataPathName = [bundlePathName stringByAppendingPathComponent: @"DataDir"]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSMutableArray *directories = [[NSMutableArray alloc] init]; for (NSString *entityName in contents) { NSString *fullEntityName = [dataPathName stringByAppendingPathComponent:entityName]; NSLog(@"entity = %@", fullEntityName); BOOL isDir = NO; [fileManager fileExistsAtPath:fullEntityName isDirectory:(&isDir)]; if (isDir) { [directories addObject:fullEntityName]; NSLog(@" is a directory"); } else { NSLog(@" is not a directory"); } } NSLog(@"Directories = %@", directories); [directories release]; } } As you can see I am trying to get a listing of directories in the app bundle's DataDir subpath. The problem is that I get no strings in my contents NSArray. note: - I am using the simulator - When I manually look in the .app file I can see DataDir and the contents therein - The contents of DataDir are png files and directories that contain png files - The application logic needs to discover the contents of DataDir at runtime - I have also tried using NSArray *contents = [fileManager contentsOfDirectoryAtPath:DataDirPathName error:nil]; and I still get no entries in my contents array Any suggestions/alternative approaches? Thanks.

  • Filter Warnings In Error List Windows In Visual Studio 2010

    - by Chuck Haines
    I just recently got the approval to upgrade our project from .NET 1.1. to .NET 4. I loaded up the project in Visual Studio 2010 and I've got it compiled and working. However as is to be expected there are over 3000 warnings I need to start looking at and handling. The problem is this solution has about 20 projects in it. So what I'd like to be able to do is filter the warnings on project. So I could say only show warnings for this project. Does anyone know if this is possible in Visual Studio 2010 or if there is an add-on I can add?

  • WPF: Bind DataGrid to List<String>

    - by Sam
    Funny, how sometimes the simple things bite me in the behind. I can bind a DataGrid nicely to a Collection of some arbitrary class, using a DataGridTextColumn like this: <DataGridTextColumn Header="Name" Binding="{Binding Name}"/> Now I want to bind a DataGrid to a simple Collection. So since there is no property "Name" or something like that to bind to, how do I write the binding: <DataGridTextColumn Header="Name" Binding="{Binding ???}"/> String has no Property "Value" or something like that. And if I just write {Binding } I'll end up with a one-way-binding, unable to write changes back to the Collection. Thinking about it, I think it is not possible to bind to a collection, so I do need to wrap my string into a class? Or is there a way?

  • python list Index out of range error

    - by dman762000
    I am working on a python tetris game that my proffessor assigned for the final project of a concepts of programming class. I have got just about everything he wanted to work on it at this point but I am having a slight problem with one part of it. Whenever I start moving pieces left and right I keep getting "index out of range error". This only happens when it is up against a piece. Here are the culprits that are giving me grief. def clearRight(block=None): global board, activeBlock, stackedBlocks isClear = True if(block == None): block = activeBlock if(block != None): for square in block['squares']: row = square[1] col = square[0]+1 if(col >= 0 and stackedBlocks[row][col] !=None): isClear=False return isClear def clearLeft(block=None): global board, activeBlock, stackedBlocks isClear = True if(block == None): block = activeBlock if(block != None): for square in block['squares']: row = square[1] col = square[0]-1 if(col >= 0 and stackedBlocks[row][col] !=None): isClear=False return isClear I am not looking to get anyone to fix it for me, I'm only looking for tips on how to fix it myself. Thanks in advance for any help that is given.

  • Optimizing a "set in a string list" to a "set as a matrix" operation

    - by Eric Fournier
    I have a set of strings which contain space-separated elements. I want to build a matrix which will tell me which elements were part of which strings. For example: "" "A B C" "D" "B D" Should give something like: A B C D 1 2 1 1 1 3 1 4 1 1 Now I've got a solution, but it runs slow as molasse, and I've run out of ideas on how to make it faster: reverseIn <- function(vector, value) { return(value %in% vector) } buildCategoryMatrix <- function(valueVector) { allClasses <- c() for(classVec in unique(valueVector)) { allClasses <- unique(c(allClasses, strsplit(classVec, " ", fixed=TRUE)[[1]])) } resMatrix <- matrix(ncol=0, nrow=length(valueVector)) splitValues <- strsplit(valueVector, " ", fixed=TRUE) for(cat in allClasses) { if(cat=="") { catIsPart <- (valueVector == "") } else { catIsPart <- sapply(splitValues, reverseIn, cat) } resMatrix <- cbind(resMatrix, catIsPart) } colnames(resMatrix) <- allClasses return(resMatrix) } Profiling the function gives me this: $by.self self.time self.pct total.time total.pct "match" 31.20 34.74 31.24 34.79 "FUN" 30.26 33.70 74.30 82.74 "lapply" 13.56 15.10 87.86 97.84 "%in%" 12.92 14.39 44.10 49.11 So my actual questions would be: - Where are the 33% spent in "FUN" coming from? - Would there be any way to speed up the %in% call? I tried turning the strings into factors prior to going into the loop so that I'd be matching numbers instead of strings, but that actually makes R crash. I've also tried going for partial matrix assignment (IE, resMatrix[i,x] <- 1) where i is the number of the string and x is the vector of factors. No dice there either, as it seems to keep on running infinitely.

  • Get value of selected field from a dropdown list

    - by 47
    I have this class in my model: class ServiceCharge(models.Model): name = models.CharField(max_length=30) amount = models.PositiveIntegerField() extends_membership = models.BooleanField(default=False) def __unicode__(self): return str(self.name) What I want to have is in the form for charging users a service charge, when a charge is selected from the dropdown menu, the two values for amount and extends_membership are updated on the form depending on the selected charge. My forms.py: class vModelChoiceField(forms.ModelChoiceField): def label_from_instance(self, obj): return "%s" % obj.name class PayServiceChargeForm(PaymentsForm): service_charge = vModelChoiceField(queryset=ServiceCharge.objects.all(), empty_label=" ") class Meta(PaymentsForm.Meta): exclude = ('member', 'payment_type', 'transacted_by', 'description') Then the form template: <table border="0"> <tr> <td><strong>{% trans "Service Charge" %}</strong></td> <td>{{ form.service_charge }}</td> <td><strong>{% trans "Extends Membership" %}</strong></td> <td>{{ form.extends_membership }}</td> </tr> <tr> <td valign="top"><strong>{% trans "Expiry Date" %}</strong></td> <td valign="top">{{ form.expiry_date }}</td> <td valign="top"><strong>{% trans "Amount" %}</strong></td> <td>{{ form.amount }}</td> </tr> </table> I was trying out some jQuery but I got stuck after getting the currently selected charge: <script type="text/javascript"> $(document).ready(function(){ $("#id_service_charge").change(onSelectChange); }); function onSelectChange(){ var selected = $("#id_service_charge option:selected"); var output = ""; if(selected.val() != 0){ charge = selected.val(); .... (update values) .... } } </script>
