  • Correcting a plist with dictionaries

    - by ingenspor
    Plist is copyed to documents directory if it doesn't exist. If it already exists, I want to use the "Name" key from NSDictionary in bundleArray to find the matching NSDictionary in documentsArray. When the match is found, I want to check for changes in the strings and replace them if there is a change. If a match is not found it means this dictionary must be added to documents plist. This is my code: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { [self managePlist]; return YES; } - (void)managePlist { NSError *error; NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *path = [documentsDirectory stringByAppendingPathComponent:@"Objects.plist"]; NSString *bundle = [[NSBundle mainBundle] pathForResource:@"Objects" ofType:@"plist"]; NSFileManager *fileManager = [NSFileManager defaultManager]; if (![fileManager fileExistsAtPath: path]) { [fileManager copyItemAtPath:bundle toPath:path error:&error]; } else { NSArray *bundleArray = [[NSArray alloc] initWithContentsOfFile:bundle]; NSMutableArray *documentArray = [[NSMutableArray alloc] initWithContentsOfFile:path]; BOOL updateDictionary = NO; for(int i=0;i<bundleArray.count;i++) { NSDictionary *bundleDict=[bundleArray objectAtIndex:i]; BOOL matchInDocuments = NO; for(int ii=0;ii<documentArray.count;ii++) { NSMutableDictionary *documentDict = [documentArray objectAtIndex:ii]; NSString *bundleObjectName = [bundleDict valueForKey:@"Name"]; NSString *documentsObjectName = [documentDict valueForKey:@"Name"]; NSRange range = [documentsObjectName rangeOfString:bundleObjectName options:NSCaseInsensitiveSearch]; if (range.location != NSNotFound) { matchInDocuments = YES; } if (matchInDocuments) { if ([bundleDict objectForKey:@"District"] != [documentDict objectForKey:@"District"]) { [documentDict setObject:[bundleDict objectForKey:@"District"] forKey:@"District"]; updateDictionary=YES; } } else { [documentArray addObject:bundleDict]; updateDictionary=YES; } } } if(updateDictionary){ [documentArray writeToFile:path atomically:YES]; } } } If I run my app now I get this message: '-[__NSCFDictionary setObject:forKey:]: mutating method sent to immutable object' How can I fix this? When this is fixed, do you think my code will work? If not, I would be happy for some suggestions on how to do this. I have struggled for a while and really need to publish the update with the corrections! Thanks a lot for your help.

  • Android googlemap Out of memory

    - by Xiaofeng
    Hi, I made an android application with googlemap api, and draw some 16x16 png (about 200 count) on overlay. When I move or zoom on/in mapview, "out of memory" error occurs very often. I also used the googlemap appication in my htc itself. Seams that it uses about 14+MB memmory, and never happens "out of memory". How to save memmory usage in a googlemap api, or how to enlarge android api memmory limit. Thanks a lot!

  • How can I filter a report with duplicate fields in related records?

    - by Graham Jones
    I have a report where I need to filter out records where there is a duplicate contract number within the same station but a different date. It is not considered a duplicate value becuase of the different date. I then need to summarize the costs and count the contracts but even if i suppress the "duplicate fields" it will summarize the value. I want to select the record with the most current date. Station Trans-DT Cost Contract-No 8 5/11/2010 10 5008 8 5/12/2010 15 5008 9 5/11/2010 12 5012 9 5/15/2010 50 5012

  • Lazy sequence or recur for mathematical power function?

    - by StackedCrooked
    As an exercise I implemented the mathematical power function. Once using recur: (defn power [a n] (let [multiply (fn [x factor i] (if (zero? i) x (recur (* x factor) factor (dec i))))] (multiply a a (dec n)))) And once with lazy-seq: (defn power [a n] (letfn [(multiply [a factor] (lazy-seq (cons a (multiply (* a factor) factor))))] (nth (multiply a a) (dec n)))) Which implementation do you think is superior? I truly have no idea.. (I'd use recur because it's easier to understand.) I read that lazy-seq is fast because is uses internal caching. But I don't see any opportunities for caching in my sample. Am I overlooking something?

  • Converting Byte[] to String - Interbase to C# - InvalidCastException

    - by NorthernOutpost
    I'm using OleDbDataReader rdr to read a "Comments" field in BLOB form (sub_type 1 segment size 80) into a string from an Interbase DB, and I keep getting exceptions. Any suggestions? Attempt #1 ls_Chap_Comments.Add((rdr["Comments"]).ToString()); InvalidCastException: The data value could not be converted for reasons other than sign mismatch or data overflow. For example, the data was corrupted in the data store but the row was still retrievable." Attempt #2 byte[] b = new byte[100]; b = (byte[])rdr["Comments"]; string s = System.Text.ASCIIEncoding.ASCII.GetString(b); InvalidCastException: Unable to cast object of type System.String to type System.Byte[] Attempt #3 // 17 is the BLOB column zero-based location for "Comments" retval = rdr.GetBytes(17, startIndex, outbyte, 0, bufferSize); InvalidCastException: Unable to cast object of type System.String to type System.Byte[]. Any suggestions would be really appreciated!

  • MC75 using symbol.imaging.device libraries for program

    - by Christy
    UPDATE: I found another library in the Windows Mobile - CameraCaptureDialog - this did the job - never did figure out the zero length available devices... Hi all, I have a .net application running on a symbol mc75 (motorola) using the scanner. I am now trying to add functionality for the camera and I am running into issues. To find the 'devices' you are supposed to use the library's 'available devices' function. With the barcode it is symbol.barcode.devices.availabledevices and it returns two items (you can scan from the scanner or using the camera device) However, when I do the camera library it does not find any devices - symbol.imaging.devices.availabledevices returns 0 I can take a picture using the software on the mc75, so I know the functionality is there, I just can't figure out how to get to it programmatically.... Does anyone have any ideas? Thanks for any help!

  • What was the most productive improvement suggestion you ever made for your team

    - by questzen
    I suggested the testing and functional teams to use Freemind map for jotting the functional flows and test steps. There was some paranoia but our module took it up and the QA teams were surprised to see near zero review comments. There was misconception among the team that there are doing more work. I assured them that by the time others would complete their work along with comment fixes, we would be going out for team lunchs and we did. The real returns came when the developers started refering to the created document in their discussions. So share your contribution(s).

  • Best real "computer crime"?

    - by c0m4
    Are there any real stories about computer crime? I'm talking about stuff like in "Office Space", stealing fractions of pennies a couple of million times... Like that, only actual events. And not Captain Crunch, please, making phone calls for free does not count. No, actual robberies or super smart frauds that depended on computer technology to some extent. Links or books for further reading please.

  • EnumJobs not returning Copies & Total Pages

    - by Hein du Plessis
    I'm using Windows API's EnumJobs to find the PageCount and Copies of a print job, but I found that these fields are almost always zero when called on a print server. Although it could be my timing is out, because the number of pages increment as the job prints and once it's done the print job cannot be accessed. So there is about half a nanosecond when the values in EnumJobs is correct before it dissapears. I've been scouring the web but can't find any help on this, just other people with similar problems. Anybody with experience with EnumJobs or can suggest other means of determining the total number of pages printed?

  • Is there a way to get each row's value from a database into an array?

    - by Guyver
    Say I have a query like the one below. What would be the best way to put each value into an array if I don't know how many results there will be? Normally I would do this with a loop, but I have no idea how many results there are. Would I need run another query to count the results first? <CFQUERY name="alllocations" DATASOURCE="#DS#"> SELECT locationID FROM tblProjectLocations WHERE projectID = '#ProjectName#' </CFQUERY>

  • exclude private property from print_r or object?

    - by Hailwood
    Basically I am using Code Igniter, and the Code Igniter base class is huge, when I print_r some of my objects they have the base class embedded inside them. this makes it a pain to get the information I actually wanted (the rest of the properties). So, I am wondering if there is a way I can hide, or remove the base class object? I have tried clone $object; unset($object->ci); print_r($object); but of course the ci property is private. the actual function I am using for dumping is: /** * Outputs the given variables with formatting and location. Huge props * out to Phil Sturgeon for this one (http://philsturgeon.co.uk/blog/2010/09/power-dump-php-applications). * To use, pass in any number of variables as arguments. * Optional pass in "true" as final argument to kill script after dump * * @return void */ function dump() { list($callee) = debug_backtrace(); $arguments = func_get_args(); $total_arguments = count($arguments); if (end($arguments) === true) $total_arguments--; echo '<fieldset style="background: #fefefe !important; border:2px red solid; padding:5px">'; echo '<legend style="background:lightgrey; padding:5px;">' . $callee['file'] . ' @ line: ' . $callee['line'] . '</legend><pre>'; $i = 0; foreach ($arguments as $argument) { //if the last argument is true we don't want to display it. if ($i == ($total_arguments) && $argument === true) break; echo '<br/><strong>Debug #' . (++$i) . ' of ' . $total_arguments . '</strong>: '; if ((is_array($argument) || is_object($argument)) && count($argument)) { print_r($argument); } else { var_dump($argument); } } echo '</pre>' . PHP_EOL; echo '</fieldset>' . PHP_EOL; //if the very last argument is "true" then die if (end($arguments) === true) die('Killing Script'); }

  • Easy way to keep counting up infinitely

    - by Andrew Alexander
    What's a good way to keep counting up infinitely? I'm trying to write a condition that will keep going until there's no value in a database, so it's going to iterate from 0, up to theoretically infinity (inside a try block, of course). How would I count upwards infinitely? Or should I use something else? I am looking for something similar to i++ in other languages, where it keeps iterating until failure.
