• Performance Counters Registry validation

  - by anchandra

  I have a C# application that adds some performance counters when it starts up. But if the registry HKEY_LOCAL_MACHINE-SOFTWARE-Microsoft-Windows NT-CurrentVersion-Perflib is corrupted (missing or invalid data), the operation of checking the existence of the performance counters (PerformanceCounterCategory.Exists(category) takes a really long time (around 30 secs) before finally throwing exception (InvalidOperation: Category does not exist). My question is how can i verify the validity of the registry before trying to add the performance counters (and what validity means) or if there is a way i can timeout the perf counter operations, so that it doesn't take 30 seconds to get an exception.

• Form Validation using Java inside PHP

  - by Mikey1980

  I have a simple problem but no matter what I try I can't see to get it to work. I have a form on a php page and I need to validate the qty value on my form so that it doesn't exceed $qty (value pulled from mySQL) and is not less than zero. Sounds easy--hmm wish it were..lol! I had it checking if the value was numeric and in my attempts to make this work I even broke that--not a good morning..lol! Here's a snip of my Java Fn: <script type='text/javascript'> function checkQty(elem){ var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression)){ return true; }else{ alert("Quantity for RMA must be greater than zero and less than original order!"); elem.focus(); return false; } } </script> The function is called from the submit button, onClick: <input type="submit" name="submit" onclick="checkQty(document.getElementById('qty')";"> I've tried: var numericExpression = /^[0-9]+$/; if(elem.value.match(numericExpression) || elem.value < 0 || elem.value > <? int($qty) ?>){ No dice....HELP!?!

• What are the best workarounds for known problems with Hibernate's schema validation of floating poin

  - by Jason Novak

  I have several Java classes with double fields that I am persisting via Hibernate. For example, I have @Entity public class Node ... private double value; When Hibernate's org.hibernate.dialect.Oracle10gDialect creates the DDL for the Node table, it maps the value field to a "double precision" type. create table MDB.Node (... value double precision not null, ... It would appear that in Oracle, "double precision" is an alias for "float". So, when I try to verify the database schema using the org.hibernate.cfg.AnnotationConfiguration.validateSchema() method, Oracle appears to describe the value column as a "float". This causes Hibernate to throw the following Exception org.hibernate.HibernateException: Wrong column type in DBO.ACL_RULE for column value. Found: float, expected: double precision A very similar problem is listed in Hibernate's JIRA database as HHH-1961 (http://opensource.atlassian.com/projects/hibernate/browse/HHH-1961). I'd like to avoid doing anything that will break MySql, Postgres, and Sql Server support so extending the Oracle10gDialect appears to be the most promising of the workarounds mentioned in HHH-1961. But extending a Dialect is something I've never done before and I'm afraid there may be some nasty gotchas. What is the best workaround for this problem that won't break our compatibility with MySql, Postgres, and Sql Server? Thanks for taking the time to look at this!

• OpenID: Trying to Get Email Address from Google OP

  - by Zaff

  I’m using dotnetopenauth 3.2 to implement Openid and can’t figure out how to get Google to pass the email address in the Claims Response. I know that Google doesn’t support simple registration, but I can’t determine what they do support. Caveat to this question is that I just started learning OpenID and I know I don’t have a solid grasp on the specification which I think is leading to my confusion. Any help would be appreciated!

• Looking for Reachability (2.0) Use Case Validation

  - by user350243

  There is so much info out there on using Apple's Reachability example, and so much is conflicting. I'm trying to find out of I'm using it (Reachability 2.0) correctly below. My App use case is this: If an internet connection is available through any means (wifi, LAN, Edge, 3G, etc.) a UIButton ("See More") is visible on various views. If no connection, the button is not visible. The "See More" part is NOT critical in any way to the app, it's just an add-on feature. "See More" could be visible or not anytime during the application lifecycle as connection is established or lost. Here's how I did it - Is this correct and/or is there a better way? Any help is Greatly Appreciated! lq // AppDelegate.h #import "RootViewController.h" @class Reachability; @interface AppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; UINavigationController *navigationController; RootViewController *rootViewController; Reachability* hostReach; // NOT USED: Reachability* internetReach; // NOT USED: Reachability* wifiReach; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet UINavigationController *navigationController; @property (nonatomic, retain) IBOutlet RootViewController *rootViewController; @end // AppDelegate.m #import "AppDelegate.h" #import "Reachability.h" #define kHostName @"www.somewebsite.com" @implementation AppDelegate @synthesize window; @synthesize navigationController; @synthesize rootViewController; - (void) updateInterfaceWithReachability: (Reachability*) curReach { if(curReach == hostReach) { NetworkStatus netStatus = [curReach currentReachabilityStatus]; BOOL connectionRequired = [curReach connectionRequired]; // Set a Reachability BOOL value flag in rootViewController // to be referenced when opening various views if ((netStatus != ReachableViaWiFi) && (netStatus != ReachableViaWWAN)) { rootViewController.bConnection = (BOOL *)0; } else { rootViewController.bConnection = (BOOL *)1; } } } - (void) reachabilityChanged: (NSNotification* )note { Reachability* curReach = [note object]; NSParameterAssert([curReach isKindOfClass: [Reachability class]]); [self updateInterfaceWithReachability: curReach]; } - (void)applicationDidFinishLaunching:(UIApplication *)application { // NOTE: #DEFINE in Reachability.h: // #define kReachabilityChangedNotification @"kNetworkReachabilityChangedNotification" [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(reachabilityChanged:) name: kReachabilityChangedNotification object: nil]; hostReach = [[Reachability reachabilityWithHostName: kHostName] retain]; [hostReach startNotifer]; [self updateInterfaceWithReachability: hostReach]; [window addSubview:[navigationController view]]; [window makeKeyAndVisible]; } - (void)dealloc { [navigationController release]; [rootViewController release]; [window release]; [super dealloc]; } @end

• Shorter Binding expression with validation

  - by Andrii V

  Hi, I'm repeating same binding parameters for every textbox and they're quite long strings (which is not good for many reasons). And I'm wondering if there's a way to make them shorter? For instance all my controls on forms are using the following binding template: Text="{Binding SourceProperty, UpdateSourceTrigger=PropertyChanged, ValidatesOnExceptions=True, ValidatesOnDataErrors=True, NotifyOnValidationError=True}" I'd would like to have something shorter that ideally will take SourceProperty as parameter. Possbly like this: Text="{MyBinding SourceProperty}" or Text="{Binding SourceProperty, Params=MyParams}" One possible option would be to inherit from Binding and create new markup extension. Did someone tried this? Any other ideas how to make these repetetive bindings look better?

• Writing a JavaScript zip code validation function

  - by mkoryak

  I would like to write a JavaScript function that validates a zip code, by checking if the zip code actually exists. Here is a list of all zip codes: http://www.census.gov/tiger/tms/gazetteer/zips.txt (I only care about the 2nd column) This is really a compression problem. I would like to do this for fun. OK, now that's out of the way, here is a list of optimizations over a straight hashtable that I can think of, feel free to add anything I have not thought of: Break zipcode into 2 parts, first 2 digits and last 3 digits. Make a giant if-else statement first checking the first 2 digits, then checking ranges within the last 3 digits. Or, covert the zips into hex, and see if I can do the same thing using smaller groups. Find out if within the range of all valid zip codes there are more valid zip codes vs invalid zip codes. Write the above code targeting the smaller group. Break up the hash into separate files, and load them via Ajax as user types in the zipcode. So perhaps break into 2 parts, first for first 2 digits, second for last 3. Lastly, I plan to generate the JavaScript files using another program, not by hand. Edit: performance matters here. I do want to use this, if it doesn't suck. Performance of the JavaScript code execution + download time. Edit 2: JavaScript only solutions please. I don't have access to the application server, plus, that would make this into a whole other problem =)

Admin like inheritance for Supervisor and Operator Project has one Admin, One supervisor and many operators. Now I want to 1. submit data for project, admin, supervisor and operator in a single project form 2. validate all and show errors on the project form. Project has_many :projects_users ; has_many :users, :through => :projects_users User has_many :projects_users ; has_many :projects, :through => :projects_users ProjectsUser = :id integer, :user_id :integer, :project_id :integer, :user_type :string ProjectUser belongs_to :project, belongs_to :user Admin < User # User has 'type:string' column for STI Supervisor < User Operator < User Is the approach correct? Any and all suggestions are welcome.

  - by Terry

  May I ask should the error catching code be placed at the lowest level or at the top as I am not sure what is the best practice? I prefer placing at the bottom, example a, as Example a public static void Main(string[] args) { string operation = args[0]; int value = Convert.ToInt32(args[1]); if (operation == "date") { DoDate(value); } else if (operation == "month") { DoMonth(value); } } public static void DoMonth(int month) { if (month < 1 || month > 12) { throw new Exception(""); } } public static void DoDate(int date) { if (date < 1 || date > 31) { throw new Exception(""); } } or example b public static void Main(string[] args) { string operation = args[0]; int value = Convert.ToInt32(args[1]); if (operation == "date" && (date < 1 || date > 12)) { throw new Exception(""); } else if (operation == "month" && (month < 1 || month > 31)) { throw new Exception(""); } if (operation == "date") { DoDate(value); } else if (operation == "month") { DoMonth(value); } } public static void DoMonth(int month) { } public static void DoDate(int date) { }

• JAX-WS: when input soap validation fails

  - by Jakob

  I have created a web service with JAX-WS. When the input SOAP message is not well formed or can not be validated, a soap fault is returned automatically to the caller. I dont want the caller to receive this standard SOAP message but i want to create an own custom SOAP fault. So if the call looks like this (note Envelope1, its not valid): hello a default return message is something like this: S:Client Couldn't create SOAP message due to exception: unexpected XML tag. expected: {http://schemas.xmlsoap.org/soap/envelope/}Envelope but found: {http://schemas.xmlsoap.org/soap/envelope/}Envelope1 I want the return message to be something like this: S:Client My own custom SOAP message! I have tried to get this to work the whole day, but i cant figure out how to do it. So if someone could help me I would be really glad!
