  • jQuery offset() not working in some browsers, on some computers

    - by Peter Di Cecco
    I have a problem positioning an element in certain browsers. I'm using the jQuery autocomplete found here. The div containing autocomplete values should be directly under the text box, and line up perfectly. The code sets the css left property of the div by using the left property generated by $(textbox).offset(); After un-packing the code to try and fix my problem, I get this: var a = $(textbox).offset(); element.css({ width: typeof e.width == "string" || e.width > 0 ? e.width : $(textbox).width(), top: a.top + textbox.offsetHeight, left: a.left }).show(); This seems like it should work, and it does work in Firefox. It doesn't work in IE8, Chrome. The top position is always correct, but the sometimes the div is too far to the left, or too far to the right. On different computers (all with Windows XP), it works in IE8... how can this be? I've also tested it on my Mac, OS 10.5. It works in Firefox, but not Safari. I've disabled plug-ins, changed screen resolutions, re-sized windows... It just inconsistently works in some places sometimes. Can anyone think of something I'm missing?

  • priority queue with limited space: looking for a good algorithm

    - by SigTerm
    This is not a homework. I'm using a small "priority queue" (implemented as array at the moment) for storing last N items with smallest value. This is a bit slow - O(N) item insertion time. Current implementation keeps track of largest item in array and discards any items that wouldn't fit into array, but I still would like to reduce number of operations further. looking for a priority queue algorithm that matches following requirements: queue can be implemented as array, which has fixed size and _cannot_ grow. Dynamic memory allocation during any queue operation is strictly forbidden. Anything that doesn't fit into array is discarded, but queue keeps all smallest elements ever encountered. O(log(N)) insertion time (i.e. adding element into queue should take up to O(log(N))). (optional) O(1) access for *largest* item in queue (queue stores *smallest* items, so the largest item will be discarded first and I'll need them to reduce number of operations) Easy to implement/understand. Ideally - something similar to binary search - once you understand it, you remember it forever. Elements need not to be sorted in any way. I just need to keep N smallest value ever encountered. When I'll need them, I'll access all of them at once. So technically it doesn't have to be a queue, I just need N last smallest values to be stored. I initially thought about using binary heaps (they can be easily implemented via arrays), but apparently they don't behave well when array can't grow anymore. Linked lists and arrays will require extra time for moving things around. stl priority queue grows and uses dynamic allocation (I may be wrong about it, though). So, any other ideas?

  • Why doesn't Perl file glob() work outside of a loop in scalar context?

    - by Rob
    According to the Perl documentation on file globbing, the <*> operator or glob() function, when used in a scalar context, should iterate through the list of files matching the specified pattern, returning the next file name each time it is called or undef when there are no more files. But, the iterating process only seems to work from within a loop. If it isn't in a loop, then it seems to start over immediately before all values have been read. From the Perl docs: In scalar context, glob iterates through such filename expansions, returning undef when the list is exhausted. http://perldoc.perl.org/functions/glob.html However, in scalar context the operator returns the next value each time it's called, or undef when the list has run out. http://perldoc.perl.org/perlop.html#I/O-Operators Example code: use warnings; use strict; my $filename; # in scalar context, <*> should return the next file name # each time it is called or undef when the list has run out $filename = <*>; print "$filename\n"; $filename = <*>; # doesn't work as documented, starts over and print "$filename\n"; # always returns the same file name $filename = <*>; print "$filename\n"; print "\n"; print "$filename\n" while $filename = <*>; # works in a loop, returns next file # each time it is called In a directory with 3 files...file1.txt, file2.txt, and file3.txt, the above code will output: file1.txt file1.txt file1.txt file1.txt file2.txt file3.txt Note: The actual perl script should be outside the test directory, or you will see the file name of the script in the output as well. Am I doing something wrong here, or is this how it is supposed to work?

  • Using .NET XmlSerializer with get properties and setter functions

    - by brone
    I'm trying to use XmlSerializer from C# to save out a class that has some values that are read by properties (the code being just a simple retrieval of field value) but set by setter functions (since there is a delegate called if the value changes). What I'm currently doing is this sort of thing. The intended use is to use the InT property to read the value, and use SetInT to set it. Setting it has side-effects, so a method is more appropriate than a property here. XmlSerializationOnly_InT exists solely for the benefit of the XmlSerializer (hence the name), and shouldn't be used by normal code. class X { public double InT { get { return _inT; } } public void SetInT(double newInT) { if (newInT != _inT) { _inT = newInT; Changed();//includes delegate call; potentially expensive } } private double _inT; // not called by normal code, as the property set is not just a simple // field set or two. [XmlElement(ElementName = "InT")] public double XmlSerializationOnly_InT { get { return InT; } set { SetInT(value); } } } This works, it's easy enough to do, and the XML file looks like you'd expect. It's manual labour though, and a bit ugly, so I'm only somewhat satisfied. What I'd really like is to be able to tell the XML serialization to read the value using the property, and set it using the setter function. Then I wouldn't need XmlSerializationOnly_InT at all. I seem to be following standard practise by distinguishing between property sets and setter functions in this way, so I'm sure I'm not the only person to have encountered this (though google suggests I might be). What have others done in this situation? Is there some easy way to persuade the XmlSerializer to handle this sort of thing better? If not, is there perhaps some other easy way to do it?

  • tikz: set appropriate x value for a node

    - by basweber
    This question resulted from the question here I want to produce a curly brace which spans some lines of text. The problem is that I have to align the x coordinate manually, which is not a clean solution. Currently I use \begin{frame}{Example} \begin{itemize} \item The long Issue 1 \tikz[remember picture] \node[coordinate,yshift=0.7em] (n1) {}; \\ spanning 2 lines \item Issue 2 \tikz[remember picture] \node[coordinate, xshift=1.597cm] (n2) {}; \item Issue 3 \end{itemize} \visible<2->{ \begin{tikzpicture}[overlay,remember picture] \draw[thick,decorate,decoration={brace,amplitude=5pt}] (n1) -- (n2) node[midway, right=4pt] {One and two are cool}; \end{tikzpicture} } % end visible \end{frame} which produces the desired result: The unsatisfying thing is, that I had to figure out the xshift value of 1.597cm by trial and error (more or less) Without xshift argument the result is: I guess there is an elegant way to avoid the explicit xshift value. The best way would it imho be to calculate the maximum x value of two nodes and use this, (as already suggested by Geoff) But it would already be very handy to be able to explicitly define the absolute xvalues of both nodes while keeping their current y values. This would avoid the fiddly procedure of adapting the third post decimal position to ensure that the brace looks vertical.

  • How to quickly generate a new string hash after concatenating 2 strings

    - by philcolbourn
    If my math is right, I can quickly generate a new hash value for the concatenation of two strings if I already have the individual hash values for each string. But only if the hash function is of the form: hash(n) = k * hash(n-1) + c(n), and h(0) = 0. In this case, hash( concat(s1,s2) ) = k**length(s2) * hash(s1) + hash(s2) eg. h1 = makeHash32_SDBM( "abcdef", 6 ); h2 = makeHash32_SDBM( "ghijklmn", 8 ); h12 = makeHash32_SDBM( "abcdefghijklmn", 14 ); hx = mod32_powI( 65599, 8 ) * h1 + h2; h1 = 2534611139 h2 = 2107082500 h12 = 1695963591 hx = 1695963591 Note that h12 = hx so this demonstrates the idea. Now, for the SDBM hash k=65599. Whereas the DJB hash has k=33 (or perhaps 31?) and h(0) = 5381 so to make it work you can set h(0) = 0 instead. But a modification on the DJB hash uses xor instead of + to add each character. http://www.cse.yorku.ca/~oz/hash.html Is there another technique to quickly calculate the hash value of concatenated strings if the hash function uses xor instead of +?

  • "<" operator error

    - by Nona Urbiz
    Why is the ( i < UniqueWords.Count ) expression valid in the for loop, but returns "CS0019 Operator '<' cannot be applied to operands of type 'int' and 'method group'" error when placed in my if? They are both string arrays, previously declared. for (int i = 0;i<UniqueWords.Count;i++){ Occurrences[i] = Words.Where(x => x.Equals(UniqueWords[i])).Count(); Keywords[i] = UniqueWords[i]; if (i<UniqueURLs.Count) {rURLs[i] = UniqueURLs[i];} } EDITED to add declarations: List<string> Words = new List<string>(); List<string> URLs = new List<string>(); //elements added like so. . . . Words.Add (referringWords); //these are strings URLs.Add (referringURL); UniqueWords = Words.Distinct().ToList(); UniqueURLs = URLs.Distinct().ToList(); SOLVED. thank you, parentheses were needed for method .Count() I still do not fully understand why they are not always necessary. Jon Skeet, thanks, I guess I don't understand what exactly the declarations are either then? You wanted the actual values assigned? They are pulled from an external source, but are strings. I get it! Thanks. (the ()'s at least.)

  • Optimize inserts

    - by ikerib
    Hi! I did an importer in VB .Net witch get data from an SQLServer an inserts this data throught ADSL connection in a remote MySQL server. in the first time, it was like 200 records, but now there are more than 500.000 records and it expends like 11hours exporting all the data and that is bad, veryyy bad. I need to optimize my importer, witch now gets the data into a datatable an them i have a function witch with a loop (row to row) inserts the data with a "insert into" query... like this: For Each dr As DataRow In dt.Rows Console.Write(".") Dim sql As String = "INSERT INTO clientes(id,nombrefis,nombrecom,direccion,codpos,municipio_id,telefono,fax,cif)" & _ "VALUES (@id,@nombrefis,@nombrecom,@direccion,@codpos,@municipio_id,@telefono,@fax,@cif)" cmd = New MySqlCommand(sql, cnn) cmd.Parameters.AddWithValue("id", Int32.Parse(dr("ID EMPRESA").ToString)) cmd.Parameters.AddWithValue("nombrefis", dr("NOMEMP")) cmd.Parameters.AddWithValue("nombrecom", dr("EMPRESA")) cmd.Parameters.AddWithValue("direccion", dr("DIRECC")) cmd.Parameters.AddWithValue("codpos", dr("CODPOS")) cmd.Parameters.AddWithValue("municipio_id", Int32.Parse(dr("CODIGO MUNICIPIO")).ToString) cmd.Parameters.AddWithValue("telefono", dr("TELEF")) cmd.Parameters.AddWithValue("fax", dr("FAX")) cmd.Parameters.AddWithValue("cif", dr("CIF")) cmd.ExecuteNonQuery() Next any ideas or advices? thanks so much

  • CLLocationDistance NaN

    - by Kaspa
    Hi, I'm trying to calculate a distance between two sets of coordinate points in an iPhone application on the fly using - (CLLocationDistance)getDistanceFrom:(const CLLocation *)location I saw that I started getting NaN's in strange places, thus investigated the matter up close, with the following hardcoded values. CLLocationDistance testDistance; placeLocation = [[CLLocation alloc] initWithLatitude:12.236533 longitude:11.011419]; userLocation = [[CLLocation alloc] initWithLatitude:12.236533 longitude:11.011419]; testDistance = [userLocation getDistanceFrom:placeLocation]; if(isnan(testDistance)) NSLog(@"ISNaN!"); [placeLocation release]; [userLocation release]; The above gets called multiple times, and in some situations the testDistance is NaN. I fear I'm missing something very simple here. Anyone have any idea? UPDATE 1: Ok, so I've moved the above code into a new project (put everything in the app delegate), looped it for 100 times and all is fine. This thus suggests that the problem is project related, but this helps very little... since all the variables are in the scope of 1 function. THE SOLUTION: OK, this seems to be a simulator bug. The same code build runs perfectly fine on the device. Case solved.

  • MS SQL datetime precision problem

    - by Nailuj
    I have a situation where two persons might work on the same order (stored in an MS SQL database) from two different computers. To prevent data loss in the case where one would save his copy of the order first, and then a little later the second would save his copy and overwrite the first, I've added a check against the lastSaved field (datetime) before saving. The code looks roughly like this: private bool orderIsChangedByOtherUser(Order localOrderCopy) { // Look up fresh version of the order from the DB Order databaseOrder = orderService.GetByOrderId(localOrderCopy.Id); if (databaseOrder != null && databaseOrder.LastSaved > localOrderCopy.LastSaved) { return true; } else { return false; } } This works for most of the time, but I have found one small bug. If orderIsChangedByOtherUser returns false, the local copy will have its lastSaved updated to the current time and then be persisted to the database. The value of lastSaved in the local copy and the DB should now be the same. However, if orderIsChangedByOtherUser is run again, it sometimes returns true even though no other user has made changes to the DB. When debugging in Visual Studio, databaseOrder.LastSaved and localOrderCopy.LastSaved appear to have the same value, but when looking closer they some times differ by a few milliseconds. I found this article with a short notice on the millisecond precision for datetime in SQL: Another problem is that SQL Server stores DATETIME with a precision of 3.33 milliseconds (0. 00333 seconds). The solution I could think of for this problem, is to compare the two datetimes and consider them equal if they differ by less than say 10 milliseconds. My question to you is then: are there any better/safer ways to compare two datetime values in MS SQL to see if they are exactly the same?

  • Sharepoint OLE DB - cannot insert records? "Field not updateable" error

    - by Pandincus
    I need to write a simple C# .NET application to retrieve, update, and insert some data in a Sharepoint list. I am NOT a Sharepoint developer, and I don't have control over our Sharepoint server. I would prefer not to have to develop this in a proper sharepoint development environment simply because I don't want to have to deploy my application on the Sharepoint server -- I'd rather just access data externally. Anyway, I found out that you can access Sharepoint data using OLE DB, and I tried it successfully using some ADO.NET: var db = DatabaseFactory.CreateDatabase(); DataSet ds = new DataSet(); using (var command = db.GetSqlStringCommand("SELECT * FROM List")) { db.LoadDataSet(command, ds, "List"); } The above works. However, when I try to insert: using (var command = db.GetSqlStringCommand("INSERT INTO List ([HeaderName], [Description], [Number]) VALUES ('Blah', 'Blah', 100)")) { db.ExecuteNonQuery(command); } I get this error: Cannot update 'HeaderName'; field not updateable. I did some Googling and apparently you cannot insert data through OLE DB! Does anyone know if there are some possible workarounds? I could try using Sharepoint Web Services, but I tried that initially and was having a heck of a time authenticating. Is that my only option?

  • A dynamic array of class "landmark", inside another single class "landmarks"

    - by pinnacler
    I'm working on a robot localization simulator and I created a class called "landmark". The end result is going to be a robot that is always centered and always faces the top of the screen. As it turns, the birds eye view map will rotate around the robot. To accomplish this, I'm assuming I can rotate one class and have all elements inside rotate as well. So, the landmark class has properties x,y, label, and radius. This is suppose to simulate a tree location in a forest. To test everything, I need "forest data," and I wrote a script to generate 100 trees in a 100m x 100m area. The script automatically generates values within an acceptable range for x,y, radius. The generated data is stored in an object called tempForest and is 100x3. Ideally, I want to create a class called "landmarks" (plural) that has 100 landmark instances inside. How would I instantiate 100 instances of landmark in one instance of landmarks using that randomly generated data? Ideally, I'd just type treeBeacons = landmarks(); and it would randomly populate 100 (user definable, set in config file) instances with x, y, radius data. I'm not sure how to deal with a dynamic array of class "Landmark", inside another single class "landmarks." Any ideas?

  • PHP get "Application Root" in Xampp on Windows correctly

    - by Michael Mao
    Hi all: I found this thread on StackOverflow about how to get the "Application Root" from inside my web app. However, most of the approaches suggested in that thread can hardly be applied to my Xampp on Windows. Say, I've got a "common.php" which stays inside my web app's app directory: / /app/common.php /protected/index.php In my common.php, what I've got is like this: define('DOCROOT', $_SERVER['DOCUMENT_ROOT']); define('ABSPATH', dirname(__FILE__)); define('COMMONSCRIPT', $_SERVER['PHP_SELF']); After I required the common.php inside the /protected/index.php, I found this: C:/xampp/htdocs //<== echo DOCROOT; C:\xampp\htdocs\comic\app //<== echo ABSPATH /comic/protected/index.php //<== echo COMMONSCRIPT So the most troublesome part is the path delimiters are not universal, plus, it seems all superglobals from the $_SERVER[] asso array, such as $_SERVER['PHP_SELF'], are relative to the "caller" script, not the "callee" script. It seems that I can only rely on dirname(__FILE__) to make sure this always returns an absolute path to the common.php file. I can certainly parse the returning values from DOCROOT and ABSPATH and then calculate the correct "application root". For instance, I can compare the parts after htdocs and substitute all backslashes with slashes to get a unix-like path I wonder is this the right way to handle this? What if I deploy my web app on a LAMP environment? would this environment-dependent approach bomb me out? I have used some PHP frameworks such as CakePHP and CodeIgniter, to be frank, They just work on either LAMP or WAMP, but I am not sure how they approached such a elegant solution. Many thanks in advance for all the hints and suggestions.

  • Is there a PHP library that performs MySQL Data Validation and Sanitization According to Column Type

    Do you know of any open source library or framework that can perform some basic validation and escaping functionality for a MySQL Db. i envisage something along the lines of: //give it something to perform the quote() quoteInto() methods $lib->setSanitizor($MyZend_DBAdaptor); //tell it structure of the table - colnames/coltypes/ etc $lib->setTableDescription($tableDescArray); //use it to validate and escape according to coltype foreach ($prospectiveData as $colName => $rawValue) if ( $lib->isValid($colName, $rawValue)) { //add it to the set clause $setValuesArray[$lib->escapeIdentifier($colName);] = $lib->getEscapedValue($colName,$rawValue); } else { throw new Exception($colName->getErrorMessage()); } etc... I have looked into - Zend_Db_Table (which knows about a table's description), and - Zend_Db_Adaptor (which knows how to escape/sanitize values depending on TYPE) but they do not automatically do any clever stuff during updates/inserts Anyone know of a good PHP library to preform this kind of validation that I could use rather than writing my own? i envisage alot of this kind of stuff: ... elseif (eregi('^INT|^INTEGER',$dataset_element_arr[col_type])) { $datatype='int'; if (eregi('unsigned',$dataset_element_arr[col_type])) { $int_max_val=4294967296; $int_min_val=0; } else { $int_max_val=2147483647; $int_min_val=-2147483648; } } (p.s I know eregi is deprecated - its just an example of laborious code)

  • Warning: passing Argument 1 of "sqlite3_bind_text" from incompatible pointer type" What should I do

    - by Amarpreet
    Hi All, i am pretty new in iphone development. I have created one function to insert data into database. The code compiles successfully. But when comes to statement sqlite3_bind_text(sqlStatement, 1, [s UTF8String], -1, SQLITE_TRANSIENT); it does not do anything but hangs AND in warning it says "passing Argument 1 of "sqlite3_bind_text" from incompatible pointer type"" for all statements in Red colour The same code i am using to fetch the data from database and its working on other viewController. Below in the code. Its pretty straightforward. Please help guys. -(void) SaveData: (NSString *)FirstName: (NSString *)LastName: (NSString *)State: (NSString *)Street: (NSString *)PostCode { databaseName = @"Zen.sqlite"; NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDire ctory, NSUserDomainMask,YES); NSString *documentsDir=[documentPaths objectAtIndex:0]; databasePath=[documentsDir stringByAppendingPathComponent:databaseName]; sqlite3 *database; if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) { const char *sqlStatement = "insert into customers (FirstName, LastName, State, Street, PostCode) values(?, ?, ?, ?, ?)"; sqlite3_stmt *compiledStatement; sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL); sqlite3_bind_text(sqlStatement, 1, [FirstName UTF8String], -1, SQLITE_TRANSIENT); sqlite3_bind_text(sqlStatement,2,[LastName UTF8String],-1,SQLITE_TRANSIENT); sqlite3_bind_text(sqlStatement,3,[State UTF8String],-1,SQLITE_TRANSIENT); sqlite3_bind_text(sqlStatement,4,[Street UTF8String],-1,SQLITE_TRANSIENT); sqlite3_bind_text(sqlStatement,5,[PostCode UTF8String],-1,SQLITE_TRANSIENT); sqlite3_step(sqlStatement); sqlite3_finalize(compiledStatement); } sqlite3_close(database); }

  • java time check API

    - by ring bearer
    I am sure this was done 1000 times in 1000 different places. The question is I want to know if there is a better/standard/faster way to check if current "time" is between two time values given in hh:mm:ss format. For example, my big business logic should not run between 18:00:00 and 18:30:00. So here is what I had in mind: public static boolean isCurrentTimeBetween(String starthhmmss, String endhhmmss) throws ParseException{ DateFormat hhmmssFormat = new SimpleDateFormat("yyyyMMddhh:mm:ss"); Date now = new Date(); String yyyMMdd = hhmmssFormat.format(now).substring(0, 8); return(hhmmssFormat.parse(yyyMMdd+starthhmmss).before(now) && hhmmssFormat.parse(yyyMMdd+endhhmmss).after(now)); } Example test case: String doNotRunBetween="18:00:00,18:30:00";//read from props file String[] hhmmss = downTime.split(","); if(isCurrentTimeBetween(hhmmss[0], hhmmss[1])){ System.out.println("NOT OK TO RUN"); }else{ System.out.println("OK TO RUN"); } What I am looking for is code that is better in performance in looks in correctness What I am not looking for third-party libraries Exception handling debate variable naming conventions method modifier issues

  • Why is iPdb not displaying STOUT after my input?

    - by BryanWheelock
    I can't figure out why ipdb is not displaying stout properly. I'm trying to debug why a test is failing and so I attempt to use ipdb debugger. For some reason my Input seems to be accepted, but the STOUT is not displayed until I (c)ontinue. Is this something broken in ipdb? It makes it very difficult to debug a program. Below is an example ipdb session, notice how I attempt to display the values of the attributes with: user.is_authenticated() user_profile.reputation user.is_superuser The results are not displayed until 'begin captured stdout ' In [13]: !python manage.py test Creating test database... < SNIP remove loading tables nosetests ...E.. /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or user.is_authenticated() user_profile.reputation user.is_superuser c F /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or c .....EE......

  • ViewModel updates after Model server roundtrip

    - by Pavel Savara
    I have stateless services and anemic domain objects on server side. Model between server and client is POCO DTO. The client should become MVVM. The model could be graph of about 100 instances of 20 different classes. The client editor contains diverse tab-pages all of them live-connected to model/viewmodel. My problem is how to propagate changes after server round-trip nice way. It's quite easy to propagate changes from ViewModel to DTO. For way back it would be possible to throw away old DTO and replace it whole with new one, but it will cause lot of redrawing for lists/DataTemplates. I could gather the server side changes and transmit them to client side. But the names of fields changed would be domain/DTO specific, not ViewModel specific. And the mapping seems nontrivial to me. If I should do it imperative way after round-trip, it would break SOC/modularity of viewModels. I'm thinking about some kind of mapping rule engine, something like automappper or emit mapper. But it solves just very plain use-cases. I don't see how it would map/propagate/convert adding items to list or removal. How to identify instances in collections so it could merge values to existing instances. As well it should propagate validation/error info. Maybe I should implement INotifyPropertyChanged on DTO and try to replay server side events on it ? And then bind ViewModel to it ? Would binding solve the problems with collection merges nice way ? Is EventAgregator from PRISM useful for that ? Is there any event record-replay component ? Is there better client side pattern for architecture with server side logic ?

  • AppEngine JDO-QL : Problem with multiple AND and OR in query

    - by KlasE
    Hi, I'm working with App Engine(Java/JDO) and are trying to do some querying with lists. So I have the following class: @PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true") public class MyEntity { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) Key key; @Persistent List<String> tags = new ArrayList<String>(); @Persistent String otherVar; } The following JDO-QL works for me: ( tags.contains('a') || tags.contains('b') || tags.contains('c') || tags.contains('d') ) && otherVar > 'a' && otherVar < 'z' This seem to return all results where tags has one or more strings with one or more of the given values and together with the inequality search on otherVar But the following do not work: (tags.contains('a') || tags.contains('_a')) && (tags.contains('b') || tags.contains('_b')) && otherVar > 'a' && otherVar < 'z' In this case I want all hits where there is at least one a (either a or _a) and one b (either b or _b) together with the inequality search as before. But the problem is that I also get back the results where there is a but no b, which is not what I want. Maybe I have missed something obvious, or done a coding error, or possibly there is a restriction on how you can write these queries in appengine, so any tips or help would be very welcome.

  • UITableViewCells of different heights place their accessoryViews at different X positions

    - by Jasarien
    Hey Guys, My app has some table cells that vary in height. The cells can also have a UIButton set to be a detail disclosure button (round, blue with arrow) as their accessory view. Depending on the height of the cell, the accessory view is positioned differently. At first I thought it was my layout code for my cell that was causing the problem, so I set up a quick independent test that uses vanilla UITableCells to remove the possibility that it could be my fault. I set up a view in interface builder, and just added a view table cells to the view, set their heights to different values and then added a detail disclosure button to each. Nothing more, nothing less. This is what I see: I added the size guides (thanks to Xscope) so you can see the difference in the accessory view x positions. The heights are: top 37px mid 68px bottom 44px (default, untouched height) If I increase the height any heigher than 68px the accessory view doesn't move any further to the left. Is this a bug? Is there any way I can prevent this from happening?
