  • Son of Suckerfish ie6 problem - right-most dropdown menu also appearing on left side of screen

    - by Kevin Burke
    I'm interning for an NGO in India and trying to fix their website, including updating their menu so it's not the last item on the page to load, and it's centered on the screen. Everything works well enough but when I try out my new menu in IE6, I get this weird error where the content below the menu is padded an extra 30px or so and the material in the right-most drop down appears on the far left of the screen, always visible. When I drop down the rightmost link ("Publications") the content appears both in the correct location and in the same spot on the far left of the screen, and changes color when I hover as well. It's tough to describe, so it would probably be best if you took a look: visit http://sevamandir.org/a30/index.htm in your Internet Explorer 6 browser to see for yourself. I really appreciate your help. Also I'm using a 1000px wide monitor, if there's more hijinks going on outside that space I'd like to know about that too. Here's the relevant code: in the html head: <script> sfHover = function() { var sfEls = document.getElementById("nav").getElementsByTagName("LI"); for (var i=0; i<sfEls.length; i++) { sfEls[i].onmouseover=function() { this.className+=" sfhover"; } sfEls[i].onmouseout=function() { this.className=this.className.replace(new RegExp(" sfhover\\b"), ""); } } } if (window.attachEvent) window.attachEvent("onload", sfHover); </script> text surrounding the menu - the menu is simply <ul id="nav"><li></li></ul> etc. <!--begin catchphrase--> <div style="float:left; height:27px; width:520px; margin:0px; font:16px Arial, Helvetica, sans-serif; font-weight:bold; color:#769841;"> Transforming lives through democratic &amp; participatory development </div> <?php include("menu.php"); ?> </div><!-- end header --> <!--begin main text div--> <div id="maincontent"> Relevant menu CSS: #nav, #nav ul { font:bold 11px Verdana, sans-serif; float: left; width: 980px; list-style: none; line-height: 1; background: white; font-weight: bold; padding: 0; border: solid #769841; border-width: 0; margin: 0 0 1em 0; } #nav a { display: block; width: 140px; /*this is the total width of the upper menu*/ w\idth: 120px; /*this is the width less horizontal padding */ padding: 5px 10px 5px 10px; /*horiz padding is the 2nd & 4th items here - goes Top Right Bottom Left */ color: #ffffff; background:#b6791e; text-decoration: none; } #nav a.daddy { background: url(rightarrow2.gif) center right no-repeat; } #nav li { float: left; padding: 0; width: 140px; /*this needs to be updated to match top #nav a */ background:#b6791e; } #nav li:hover, #nav li a:hover, #nav li:hover a { background:#769841; } #nav li:hover li a { background:#ffffff; color:#769841; } #nav li ul { position: absolute; left: -999em; height: auto; width: 14.4em; w\idth: 13.9em; font-weight: bold; border-width: 0.25em; /*green border around dropdown menu*/ margin: 0; } #nav li ul a { background:#ffffff; color:#769841; } #nav li li { padding-right: 1em; width: 13em; background:#ffffff; } #nav li ul a { width: 13em; w\idth: 9em; } #nav li ul ul { margin: -1.75em 0 0 14em; } #nav li:hover ul ul, #nav li:hover ul ul ul, #nav li.sfhover ul ul, #nav li.sfhover ul ul ul { left: -999em; } #nav li:hover ul, #nav li li:hover ul, #nav li li li:hover ul, #nav li.sfhover ul, #nav li li.sfhover ul, #nav li li li.sfhover ul { left: auto; } #nav li:hover, #nav li.sfhover, { background: #769841; color:#ffe400; } #nav li a:hover, #nav li li a:hover, #nav li:hover li:hover, #nav li.sfhover a:hover { background: #769841; color:#ffe400; }

  • NSOutlineView not refreshing when objects added to managed object context from NSOperations

    - by John Gallagher
    Background Cocoa app using core data Two processes - daemon and a main UI Daemon constantly writing to a data store UI process reads from same data store NSOutlineView in UI is bound to an NSTreeController which is bound to Application with key path of delegate.interpretedMOC What I want When the UI is activated, the outline view should update with the latest data inserted by the daemon. The Problem Main Thread Approach I fetch all the entities I'm interested in, then iterate over them, doing refreshObject:mergeChanges:YES. This works OK - the items get refreshed correctly. However, this is all running on the main thread, so the UI locks up for 10-20 seconds whilst it refreshes. Fine, so let's move these refreshes to NSOperations that run in the background instead. NSOperation Multithreaded Approach As soon as I move the refreshObject:mergeChanges: call into an NSOperation, the refresh no longer works. When I add logging messages, it's clear that the new objects are loaded in by the NSOperation subclass and refreshed. Not only that, but they are What I've tried I've messed around with this for 2 days solid and tried everything I can think of. Passing objectIDs to the NSOperation to refresh instead of an entity name. Resetting the interpretedMOC at various points - after the data refresh and before the outline view reload. I'd subclassed NSOutlineView. I discarded my subclass and set the view back to being an instance of NSOutlineView, just in case there was any funny goings on here. Added a rearrangeObjects call to the NSTreeController before reloading the NSOutlineView data. Made sure I had set the staleness interval to 0 on all managed object contexts I was using. I've got a feeling this problem is somehow related to caching core data objects in memory. But I've totally exhausted all my ideas on how I get this to work. I'd be eternally grateful of any ideas anyone else has. Code Main Thread Approach // In App Delegate -(void)applicationDidBecomeActive:(NSNotification *)notification { // Delay to allow time for the daemon to save [self performSelector:@selector(refreshTrainingEntriesAndGroups) withObject:nil afterDelay:3]; } -(void)refreshTrainingEntriesAndGroups { NSSet *allTrainingGroups = [[[NSApp delegate] interpretedMOC] fetchAllObjectsForEntityName:kTrainingGroup]; for(JGTrainingGroup *thisTrainingGroup in allTrainingGroups) [interpretedMOC refreshObject:thisTrainingGroup mergeChanges:YES]; NSError *saveError = nil; [interpretedMOC save:&saveError]; [windowController performSelectorOnMainThread:@selector(refreshTrainingView) withObject:nil waitUntilDone:YES]; } // In window controller class -(void)refreshTrainingView { [trainingViewTreeController rearrangeObjects]; // Didn't really expect this to have any effect. And it didn't. [trainingView reloadData]; } NSOperation Multithreaded Approach // In App Delegate -(void)refreshTrainingEntriesAndGroups { JGRefreshEntityOperation *trainingGroupRefresh = [[JGRefreshEntityOperation alloc] initWithEntityName:kTrainingGroup]; NSOperationQueue *refreshQueue = [[NSOperationQueue alloc] init]; [refreshQueue setMaxConcurrentOperationCount:1]; [refreshQueue addOperation:trainingGroupRefresh]; while ([[refreshQueue operations] count] > 0) { [[NSRunLoop currentRunLoop] runUntilDate:[NSDate dateWithTimeIntervalSinceNow:0.05]]; [windowController performSelectorOnMainThread:@selector(refreshTrainingView) withObject:nil waitUntilDone:YES]; } // JGRefreshEntityOperation.m @implementation JGRefreshEntityOperation @synthesize started; @synthesize executing; @synthesize paused; @synthesize finished; -(void)main { [self startOperation]; NSSet *allEntities = [imoc fetchAllObjectsForEntityName:entityName]; for(id thisEntity in allEntities) [imoc refreshObject:thisEntity mergeChanges:YES]; [self finishOperation]; } -(void)startOperation { [self willChangeValueForKey:@"isExecuting"]; [self willChangeValueForKey:@"isStarted"]; [self setStarted:YES]; [self setExecuting:YES]; [self didChangeValueForKey:@"isExecuting"]; [self didChangeValueForKey:@"isStarted"]; imoc = [[NSManagedObjectContext alloc] init]; [imoc setStalenessInterval:0]; [imoc setUndoManager:nil]; [imoc setPersistentStoreCoordinator:[[NSApp delegate] interpretedPSC]]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(mergeChanges:) name:NSManagedObjectContextDidSaveNotification object:imoc]; } -(void)finishOperation { saveError = nil; [imoc save:&saveError]; if (saveError) { NSLog(@"Error saving. %@", saveError); } imoc = nil; [self willChangeValueForKey:@"isExecuting"]; [self willChangeValueForKey:@"isFinished"]; [self setExecuting:NO]; [self setFinished:YES]; [self didChangeValueForKey:@"isExecuting"]; [self didChangeValueForKey:@"isFinished"]; } -(void)mergeChanges:(NSNotification *)notification { NSManagedObjectContext *mainContext = [[NSApp delegate] interpretedMOC]; [mainContext performSelectorOnMainThread:@selector(mergeChangesFromContextDidSaveNotification:) withObject:notification waitUntilDone:YES]; } -(id)initWithEntityName:(NSString *)entityName_ { [super init]; [self setStarted:false]; [self setExecuting:false]; [self setPaused:false]; [self setFinished:false]; [NSThread setThreadPriority:0.0]; entityName = entityName_; return self; } @end // JGRefreshEntityOperation.h @interface JGRefreshEntityOperation : NSOperation { NSString *entityName; NSManagedObjectContext *imoc; NSError *saveError; BOOL started; BOOL executing; BOOL paused; BOOL finished; } @property(readwrite, getter=isStarted) BOOL started; @property(readwrite, getter=isPaused) BOOL paused; @property(readwrite, getter=isExecuting) BOOL executing; @property(readwrite, getter=isFinished) BOOL finished; -(void)startOperation; -(void)finishOperation; -(id)initWithEntityName:(NSString *)entityName_; -(void)mergeChanges:(NSNotification *)notification; @end

  • Logging raw HTTP request/response in ASP.NET MVC & IIS7

    - by Greg Beech
    I'm writing a web service (using ASP.NET MVC) and for support purposes we'd like to be able to log the requests and response in as close as possible to the raw, on-the-wire format (i.e including HTTP method, path, all headers, and the body) into a database. What I'm not sure of is how to get hold of this data in the least 'mangled' way. I can re-constitute what I believe the request looks like by inspecting all the properties of the HttpRequest object and building a string from them (and similarly for the response) but I'd really like to get hold of the actual request/response data that's sent on the wire. I'm happy to use any interception mechanism such as filters, modules, etc. and the solution can be specific to IIS7. However, I'd prefer to keep it in managed code only. Any recommendations? Edit: I note that HttpRequest has a SaveAs method which can save the request to disk but this reconstructs the request from the internal state using a load of internal helper methods that cannot be accessed publicly (quite why this doesn't allow saving to a user-provided stream I don't know). So it's starting to look like I'll have to do my best to reconstruct the request/response text from the objects... groan. Edit 2: Please note that I said the whole request including method, path, headers etc. The current responses only look at the body streams which does not include this information. Edit 3: Does nobody read questions around here? Five answers so far and yet not one even hints at a way to get the whole raw on-the-wire request. Yes, I know I can capture the output streams and the headers and the URL and all that stuff from the request object. I already said that in the question, see: I can re-constitute what I believe the request looks like by inspecting all the properties of the HttpRequest object and building a string from them (and similarly for the response) but I'd really like to get hold of the actual request/response data that's sent on the wire. If you know the complete raw data (including headers, url, http method, etc.) simply cannot be retrieved then that would be useful to know. Similarly if you know how to get it all in the raw format (yes, I still mean including headers, url, http method, etc.) without having to reconstruct it, which is what I asked, then that would be very useful. But telling me that I can reconstruct it from the HttpRequest/HttpResponse objects is not useful. I know that. I already said it. Please note: Before anybody starts saying this is a bad idea, or will limit scalability, etc., we'll also be implementing throttling, sequential delivery, and anti-replay mechanisms in a distributed environment, so database logging is required anyway. I'm not looking for a discussion of whether this is a good idea, I'm looking for how it can be done.

  • How to add objects to association in OnPreInsert, OnPreUpdate

    - by Dmitriy Nagirnyak
    Hi, I have an event listener (for Audit Logs) which needs to append audit log entries to the association of the object: public Company : IAuditable { // Other stuff removed for bravety IAuditLog IAuditable.CreateEntry() { var entry = new CompanyAudit(); this.auditLogs.Add(entry); return entry; } public virtual IEnumerable<CompanyAudit> AuditLogs { get { return this.auditLogs } } } The AuditLogs collection is mapped with cascading: public class CompanyMap : ClassMap<Company> { public CompanyMap() { // Id and others removed fro bravety HasMany(x => x.AuditLogs).AsSet() .LazyLoad() .Access.ReadOnlyPropertyThroughCamelCaseField() .Cascade.All(); } } And the listener just asks the auditable object to create log entries so it can update them: internal class AuditEventListener : IPreInsertEventListener, IPreUpdateEventListener { public bool OnPreUpdate(PreUpdateEvent ev) { var audit = ev.Entity as IAuditable; if (audit == null) return false; Log(audit); return false; } public bool OnPreInsert(PreInsertEvent ev) { var audit = ev.Entity as IAuditable; if (audit == null) return false; Log(audit); return false; } private static void LogProperty(IAuditable auditable) { var entry = auditable.CreateAuditEntry(); entry.CreatedAt = DateTime.Now; entry.Who = GetCurrentUser(); // Might potentially execute a query. // Also other information is set for entry here } } The problem with it though is that it throws TransientObjectException when commiting the transaction: NHibernate.TransientObjectException : object references an unsaved transient instance - save the transient instance before flushing. Type: PropConnect.Model.UserAuditLog, Entity: PropConnect.Model.UserAuditLog at NHibernate.Engine.ForeignKeys.GetEntityIdentifierIfNotUnsaved(String entityName, Object entity, ISessionImplementor session) at NHibernate.Type.EntityType.GetIdentifier(Object value, ISessionImplementor session) at NHibernate.Type.ManyToOneType.NullSafeSet(IDbCommand st, Object value, Int32 index, Boolean[] settable, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.WriteElement(IDbCommand st, Object elt, Int32 i, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.PerformInsert(Object ownerId, IPersistentCollection collection, IExpectation expectation, Object entry, Int32 index, Boolean useBatch, Boolean callable, ISessionImplementor session) at NHibernate.Persister.Collection.AbstractCollectionPersister.Recreate(IPersistentCollection collection, Object id, ISessionImplementor session) at NHibernate.Action.CollectionRecreateAction.Execute() at NHibernate.Engine.ActionQueue.Execute(IExecutable executable) at NHibernate.Engine.ActionQueue.ExecuteActions(IList list) at NHibernate.Engine.ActionQueue.ExecuteActions() at NHibernate.Event.Default.AbstractFlushingEventListener.PerformExecutions(IEventSource session) at NHibernate.Event.Default.DefaultFlushEventListener.OnFlush(FlushEvent event) at NHibernate.Impl.SessionImpl.Flush() at NHibernate.Transaction.AdoTransaction.Commit() As the cascading is set to All I expected NH to handle this. I also tried to modify the collection using state but pretty much the same happens. So the question is what is the last chance to modify object's associations before it gets saved? Thanks, Dmitriy.

  • May volatile be in user defined types to help writing thread-safe code

    - by David Rodríguez - dribeas
    I know, it has been made quite clear in a couple of questions/answers before, that volatile is related to the visible state of the c++ memory model and not to multithreading. On the other hand, this article by Alexandrescu uses the volatile keyword not as a runtime feature but rather as a compile time check to force the compiler into failing to accept code that could be not thread safe. In the article the keyword is used more like a required_thread_safety tag than the actual intended use of volatile. Is this (ab)use of volatile appropriate? What possible gotchas may be hidden in the approach? The first thing that comes to mind is added confusion: volatile is not related to thread safety, but by lack of a better tool I could accept it. Basic simplification of the article: If you declare a variable volatile, only volatile member methods can be called on it, so the compiler will block calling code to other methods. Declaring an std::vector instance as volatile will block all uses of the class. Adding a wrapper in the shape of a locking pointer that performs a const_cast to release the volatile requirement, any access through the locking pointer will be allowed. Stealing from the article: template <typename T> class LockingPtr { public: // Constructors/destructors LockingPtr(volatile T& obj, Mutex& mtx) : pObj_(const_cast<T*>(&obj)), pMtx_(&mtx) { mtx.Lock(); } ~LockingPtr() { pMtx_->Unlock(); } // Pointer behavior T& operator*() { return *pObj_; } T* operator->() { return pObj_; } private: T* pObj_; Mutex* pMtx_; LockingPtr(const LockingPtr&); LockingPtr& operator=(const LockingPtr&); }; class SyncBuf { public: void Thread1() { LockingPtr<BufT> lpBuf(buffer_, mtx_); BufT::iterator i = lpBuf->begin(); for (; i != lpBuf->end(); ++i) { // ... use *i ... } } void Thread2(); private: typedef vector<char> BufT; volatile BufT buffer_; Mutex mtx_; // controls access to buffer_ };

  • Need an end of lexical scope action which can die normally

    - by Schwern
    I need the ability to add actions to the end of a lexical block where the action might die. And I need the exception to be thrown normally and be able to be caught normally. Unfortunately, Perl special cases exceptions during DESTROY both by adding "(in cleanup)" to the message and making them untrappable. For example: { package Guard; use strict; use warnings; sub new { my $class = shift; my $code = shift; return bless $code, $class; } sub DESTROY { my $self = shift; $self->(); } } use Test::More tests => 2; my $guard_triggered = 0; ok !eval { my $guard = Guard->new( #line 24 sub { $guard_triggered++; die "En guarde!" } ); 1; }, "the guard died"; is $@, "En guarde! at $@ line 24\n", "with the right error message"; is $guard_triggered, 1, "the guard worked"; I want that to pass. Currently the exception is totally swallowed by the eval. This is for Test::Builder2, so I cannot use anything but pure Perl. The underlying issue is I have code like this: { $self->setup; $user_code->(); $self->cleanup; } That cleanup must happen even if the $user_code dies, else $self gets into a weird state. So I did this: { $self->setup; my $guard = Guard->new(sub { $self->cleanup }); $user_code->(); } The complexity comes because the cleanup runs arbitrary user code and it is a use case where that code will die. I expect that exception to be trappable and unaltered by the guard. I'm avoiding wrapping everything in eval blocks because of the way that alters the stack.

  • Anchor bug on IE9, anchor hitbox overlapped

    - by user1456399
    The menu below works just fine in Firefox and Chrome, but in IE9, but hitbox for the "HOME" anchor is being covered partially by the list item behind it except for the actual test, and a single horizontal pixel line at the top and bottom of the button. Can anyone see what I'm missing? Code to follow: index.html <html lang="en"> <head> <meta http-equiv="Content-Type" content="text/html;charset=utf-8" > <title>Navigation</title> <style> .menu-container { width:960px; height:45px; margin:0 auto; position:relative; z-index:2; background-color: #3d3d3d; margin-bottom: 20px; } .menu-navigation { font-family:Arial, Helvetica, sans-serif; font-size:13px; list-style:none; padding:0; margin:0; text-align: right; font-size: 0; /* Removes whitespace between <li> */ } .menu-navigation > li { display:inline; margin:0; border-left:solid 1px #242424; background-color:transparent; font-size: 12px; padding: 15px 0 15px 0; } .menu-navigation > li:hover, .menu-navigation > li.current-menu-item { background-color:#202020; } .menu-navigation > li.active, .menu-navigation > li.active:hover { background-color:#131313; } .menu-navigation > li a { text-decoration:none; color:#bbbbbb; } .menu-navigation > li a:hover { color:#efefef; } .menu-navigation > li span a { color:#ffffff; } .menu-navigation > li a:focus { outline:none; } .menu-navigation > li.menu-item-parent > span, .menu-navigation > li > span > a { text-transform:uppercase; outline:0; text-decoration:none; color:#ffffff; text-shadow:1px 1px 1px #000000; line-height: 45px; display: inline-block; height: 45px; padding: 0 20px 0 20px; } .menu-navigation > li.menu-item-parent > span { background:url("../img/down.png") no-repeat right center; } .menu-navigation > li.menu-item-parent > span:hover, .menu-navigation > li > span > a:hover { cursor:pointer; } </style> </head> <body> <div class="menu-container"> <ul class="menu-navigation"> <li><span><a href="#">This is a link</a></span></li> <li><span><a href="#">This is a link</a></span></li> <li class="menu-item-parent"><span>Not a link</span></li> <li class="menu-item-parent"><span>Not a link</span></li> <li class="menu-item-parent"><span>Not a link</span></li> </ul> </div> </body> </html> EDIT: Alright, I've changed the code to isolate the issue, and narrowed down the problem CSS. Simply adding a background image fixes the issue. The code is set up so it styles so the hit boxes for all the menu items are the same regardless if there's a link in them or not to facilitate an "onClick" drop down on those menu items without anchors. Refer to lines 81 - 86. Remove those lines (just a background image), and the hit box issue is seen in the menu items "NOT A LINK" as well. Further, the act of adding a background image fixes the hit box issue of "THIS IS A LINK" menu items. Simply add the following snippet to the CSS: .menu-navigation > li > span > a { background:url("../img/down.png") no-repeat right center; } Adding a background image, even if there is no actual image, is changing something with regards to the hit box... I'm just not sure what...

  • PL/SQL pre-compile and Code Quality checks in an automatted build environment?

    - by Lars Corneliussen
    We build software using Hudson and Maven. We have C#, java and last, but not least PL/SQL sources (sprocs, packages, DDL, crud) For C# and Java we do unit tests and code analysis, but we don't really know the health of our PL/SQL sources before we actually publish them to the target database. Requirements There are a couple of things we wan't to test in the following priority: Are the sources valid, hence "compilable"? For packages, with respect to a certain database, would they compile? Code Quality: Do we have code flaws like duplicates, too complex methods or other violations to a defined set of rules? Also, the tool must run head-less (commandline, ant, ...) we wan't to do analysis on a partial code base (changed sources only) Tools We did a little research and found the following tools that could potencially help: Cast Application Intelligence Platform (AIP): Seems to be a server that grasps information about "anything". Couldn't find a console version that would export in readable format. Toad for Oracle: The Professional version is said to include something called Xpert validates a set of rules against a code base. Sonar + PL/SQL-Plugin: Uses Toad for Oracle to display code-health the sonar-way. This is for browsing the current state of the code base. Semantic Designs DMSToolkit: Quite general analysis of source code base. Commandline available? Semantic Designs Clones Detector: Detects clones. But also via command line? Fortify Source Code Analyzer: Seems to be focussed on security issues. But maybe it is extensible? more... So far, Toad for Oracle together with Sonar seems to be an elegant solution. But may be we are missing something here? Any ideas? Other products? Experiences?

  • Can ping device from one computer and not the other

    - by Sean Duggan
    I've recently been assigned to work on a diagnostic program done in C++ which communicates with a piece of electronic equipment. Our normal scenario involves communicating via an RS232 interface, but I've been asked to make our program work over ethernet, source code having been done in Visual Basic. After much thrashing about trying to get the code to work and continuing to get 10049 Winsock errors when I tried to connect, I tried pinging the switch. From the computer the VB program is running on, I can see the switch via ping, nslookup, tracert, and pathping (I was going down the list of programs) and I can do this via URI or IP address. From my laptop, sending the same commands fails every time. They're both using the same network cable and the same USB-to-Ethernet device (I've been swapping them between tests) but one can see the switch and the other cannot. I'm working on the programming end, but the ping results makes me think that there might be a network issue stymieing me. wry grin I'm not much of a network guy, so I'm appealing to expert assistance. Both computers are running Windows XP if that helps. The connection is to an "IP-RS8" device which then connects to our VCU-C units. Each unit is accessible via URI or IP address on the desktop computer we usually have connected to the units (it's running the older VB program that I was asked to lift the networking code from). The connection is made via a USB-to-Ethernet adapter so as to leave the regular Ethernet port available for connecting to the company network. Hmm... come to think of it, I've probably been confusing the issue, talking about pinging "the switch" rather than indicating that it's the devices. My apologies. Communication is generally done with a DLL that uses Winsock functions to make queries for data from the VCU and then to receive. I'm failing when connecting. I haven't found anything on the firewall which should block these commands, but I'll keep poking.

  • .NET 2.0 Process Elevation for App Installation

    - by Brian Gillespie
    We have an application written in both C++ and .NET that installs for all users in the Program Files folder. This application downloads new versions of itself (as MSI installers) and spawns the new installer process to replace itself. The install process as it exists today: Copy an install manager app (C#, .NET 2.0) to the temp directory. Call this 'Manager' Manager is executed with elevated privs per this article. The original application exits. Manager spawns the MSI installer (with elevated privs, since the copy is elevated) Manager spawns the new version of the app. The bug: The newly installed app is running in an elevated state. This causes problems I won't enumerate here. Ideally, the launch of the newly installed app would be run with the permissions of the original user. I can't figure out how to demote the app back to being the standard user after elevation. An inelegant hack: (yeah, yeah, this whole process is inelegant anyway) Copy the install manager to the temp directory Run the install manager with standard user privs. Lets call this instance 'LowlyManager'. Original application exits. LowlyManager spawns the app again, this time with elevated privs. Let's name this instance 'UpperManagement' UpperManagement spawns the installer UpperManagement exits gracefully, returning the exit code of the installer. LowlyManager interprets the error code from UpperManagement, and spawns the newly installed application. This time as the original invoker. Is there a better way to do this? (I've left out a bunch of other details before and after these steps that make the process smoother for the user, but this should be enough to understand the core of the problem I'm trying to solve.) Other requirements: We can't install as a per-user app The user shouldn't be presented with an authentication dialog box if UAC would have simply asked "are you sure you want to allow this?". I think this might kill a solution using WindowsImpersonationContext, but I'm not sure. The system needs to work on XP, Vista, and Windows 7 (even if there is a separate process for XP).

  • No value given for one or more required parameters in connection initialisation

    - by DarkJaff
    Hi everyone, I have an C# form application that use an access database. This application works perfectly in debug and release. It works on all version of Windows. But it crash on one computer with Windows 7. The message I got is: System.Data.OleDb.OleDbException: No value given for one or more required parameters. The function that is supposely not working is this: public void InitConnection(string strFile) { string strConnection = String.Format("Provider=Microsoft.Jet.OLEDB.4.0;Data Source={0};User Id=admin;Password=;", strFile); m_conn = new OleDbConnection(strConnection); try { //On vérifie si la connexion n'est pas ouverte if (m_conn.State != ConnectionState.Open) { m_conn.Open(); m_VCoeffModele = GetModeleCoeff(); } } catch (Exception err) { throw err; } } I think it's something related to the connection string but why only on that computer.

  • Binding CoreData Managed Object to NSTextFieldCell subclass

    - by ndg
    I have an NSTableView which has its first column set to contain a custom NSTextFieldCell. My custom NSTextFieldCell needs to allow the user to edit a "desc" property within my Managed Object but to also display an "info" string that it contains (which is not editable). To achieve this, I followed this tutorial. In a nutshell, the tutorial suggests editing your Managed Objects generated subclass to create and pass a dictionary of its contents to your NSTableColumn via bindings. This works well for read-only NSCell implementations, but I'm looking to subclass NSTextFieldCell to allow the user to edit the "desc" property of my Managed Object. To do this, I followed one of the articles comments, which suggests subclassing NSFormatter to explicitly state which Managed Object property you would like the NSTextFieldCell to edit. Here's the suggested implementation: @implementation TRTableDescFormatter - (BOOL)getObjectValue:(id *)anObject forString:(NSString *)string errorDescription:(NSString **)error { if (anObject != nil){ *anObject = [NSDictionary dictionaryWithObject:string forKey:@"desc"]; return YES; } return NO; } - (NSString *)stringForObjectValue:(id)anObject { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; return [anObject valueForKey:@"desc"]; } - (NSAttributedString*)attributedStringForObjectValue:(id)anObject withDefaultAttributes:(NSDictionary *)attrs { if (![anObject isKindOfClass:[NSDictionary class]]) return nil; NSAttributedString *anAttributedString = [[NSAttributedString alloc] initWithString: [anObject valueForKey:@"desc"]]; return anAttributedString; } @end I assign the NSFormatter subclass to my cell in my NSTextFieldCell subclass, like so: - (void)awakeFromNib { TRTableDescFormatter *formatter = [[[TRTableDescFormatter alloc] init] autorelease]; [self setFormatter:formatter]; } This seems to work, but falls down when editing multiple rows. The behaviour I'm seeing is that editing a row will work as expected until you try to edit another row. Upon editing another row, all previously edited rows will have their "desc" value set to the value of the currently selected row. I've been doing a lot of reading on this subject and would really like to get to the bottom of this. What's more frustrating is that my NSTextFieldCell is rendering exactly how I would like it to. This editing issue is my last obstacle! If anyone can help, that would be greatly appreciated.

  • Wiring up JavaScript handlers after a Partial Postback in ASP.NET

    - by Richard
    I am trying to use LinkButtons with the DefaultButton property of the ASP.NET Panel in an UpdatePanel. I have read and used the various other answers that are around describing the wiring up of the click event so that a full postback is not done instead of a partial postback. When the page loads, I wire up the .click function of the LinkButton so that the DefaultButton property of the ASP.NET panel will work. This all works fine, until you bring an UpdatePanel into the mix. With an UpdatePanel, if there is a partial postback, the script to wire up the .click function is not called in the partial postback, and hitting enter reverts to causing a full submit of the form rather than triggering the LinkButton. How can I cause javascript to be executed after a partial postback to re-wire up the .click function of the LinkButton? I have produced a sample page which shows the problem. There are two alerts showing 1) When the code to hook up the .click function is being called, and 2) When the .click function has been called (this only happens when you hit enter in the textbox after the event has been wired up). To test this code, type something in the textbox and hit Enter. The text will be copied to the label control, but "Wiring up Event Click" alert will not be shown. Add another letter, hit enter again, and you'll get a full postback without the text being copied to the label control (as the LinkButton wasn't called). Because that was a full postback, the Wiring Up Event Click event will be called again, and the form will work properly the next time again. This is being done with ASP.NET 3.5. Test Case Code: <%@ Page Language="C#" Inherits="System.Web.UI.Page" Theme="" EnableTheming="false" AutoEventWireup="true" %> <script runat="server"> void cmdComplete_Click(object sender, EventArgs e) { lblOutput.Text = "Complete Pressed: " + txtInput.Text; } void cmdFirstButton_Click(object sender, EventArgs e) { lblOutput.Text = "First Button Pressed"; } protected override void OnLoad(EventArgs e) { HookupButton(cmdComplete); } void HookupButton(LinkButton button) { // Use the click event of the LinkButton to trigger the postback (this is used by the .click code below) button.OnClientClick = Page.ClientScript.GetPostBackEventReference(button, String.Empty); // Wire up the .click event of the button to call the onclick function, and prevent a form submit string clickString = string.Format(@" alert('Wiring up click event'); document.getElementById('{0}').click = function() {{ alert('Default button pressed'); document.getElementById('{0}').onclick(); }};", button.ClientID, Page.ClientScript.GetPostBackEventReference(button, "")); Page.ClientScript.RegisterStartupScript(button.GetType(), "click_hookup_" + button.ClientID, clickString, true); } </script> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>DefaultButton/LinkButton Testing</title> <style type="text/css"> a.Button { line-height: 2em; padding: 5px; border: solid 1px #CCC; background-color: #EEE; } </style> </head> <body> <h1> DefaultButton/LinkButton Testing</h1> <form runat="server"> <asp:ScriptManager runat="server" /> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <ContentTemplate> <div style="position: relative"> <fieldset> <legend>Output</legend> <asp:Label runat="server" ID="lblOutput" /> </fieldset> <asp:Button runat="server" Text="First Button" ID="cmdFirstButton" OnClick="cmdFirstButton_Click" UseSubmitBehavior="false" /> <asp:Panel ID="Panel1" runat="server" DefaultButton="cmdComplete"> <label> Enter Text:</label> <asp:TextBox runat="server" ID="txtInput" /> <asp:LinkButton runat="server" CssClass="Button" ID="cmdComplete" OnClick="cmdComplete_Click" Text="Complete" /> </asp:Panel> </div> </ContentTemplate> </asp:UpdatePanel> <asp:Button runat="server" ID="cmdFullPostback" Text="Full Postback" /> </form> </body> </html>

  • BindException/Too many file open while using HttpClient under load

    - by Langali
    I have got 1000 dedicated Java threads where each thread polls a corresponding url every one second. public class Poller { public static Node poll(Node node) { GetMethod method = null; try { HttpClient client = new HttpClient(new SimpleHttpConnectionManager(true)); ...... } catch (IOException ex) { ex.printStackTrace(); } finally { method.releaseConnection(); } } } The threads are run every one second: for (int i=0; i <1000; i++) { MyThread thread = threads.get(i) // threads is a static field if(thread.isAlive()) { // If the previous thread is still running, let it run. } else { thread.start(); } } The problem is if I run the job every one second I get random exceptions like these: java.net.BindException: Address already in use INFO httpclient.HttpMethodDirector: I/O exception (java.net.BindException) caught when processing request: Address already in use INFO httpclient.HttpMethodDirector: Retrying request But if I run the job every 2 seconds or more, everything runs fine. I even tried shutting down the instance of SimpleHttpConnectionManager() using shutDown() with no effect. If I do netstat, I see thousands of TCP connections in TIME_WAIT state, which means they are have been closed and are clearing up. So to limit the no of connections, I tried using a single instance of HttpClient and use it like this: public class MyHttpClientFactory { private static MyHttpClientFactory instance = new HttpClientFactory(); private MultiThreadedHttpConnectionManager connectionManager; private HttpClient client; private HttpClientFactory() { init(); } public static HttpClientFactory getInstance() { return instance; } public void init() { connectionManager = new MultiThreadedHttpConnectionManager(); HttpConnectionManagerParams managerParams = new HttpConnectionManagerParams(); managerParams.setMaxTotalConnections(1000); connectionManager.setParams(managerParams); client = new HttpClient(connectionManager); } public HttpClient getHttpClient() { if (client != null) { return client; } else { init(); return client; } } } However after running for exactly 2 hours, it starts throwing 'too many open files' and eventually cannot do anything at all. ERROR java.net.SocketException: Too many open files INFO httpclient.HttpMethodDirector: I/O exception (java.net.SocketException) caught when processing request: Too many open files INFO httpclient.HttpMethodDirector: Retrying request I should be able to increase the no of connections allowed and make it work, but I would just be prolonging the evil. Any idea what is the best practise to use HttpClient in a situation like above? Btw, I am still on HttpClient3.1.

  • Agilent E4426B signal generator locks up during multiple GPIB *SAV operations

    - by aspiehler
    I have a test fixture with an Agilent E4426B RF signal generator connected to a PC via a National Instrument Ethernet-to-GPIB bridge. My software is attempting to sanitize the instrument by presetting it and then saving the current state to all of the memory locations writable via the standard SCPI command "*SAV x,y". The loop works to a point, but eventually the instrument responds with an error and continuously displays the "L" icon on the front display and a "Remote preset" message at the bottom. At that point it won't respond to any more remote commands and I have to either cycle power or press LOCAL, then PRESET at which point it takes about 3 minutes to finish presetting. At that point the "L" icon is still present and and the next GPIB command sent to the instrument causes it to report a -113 error (undefined header) in the instrument error queue. I fired up NI spy to see what was happening, and found that the error was happening at the same point in the loop - "*SAV 6,2" in this case. From NI Spy: Send (0, 0x0017, "*SAV 6,2", 8 (0x8), NLend (0,0x01)) Process ID: 0x00000520 Thread ID: 0x00000518 ibsta:0xc168 iberr: 6 ibcntl: 2(0x2) And here's the code from the instrument driver: int CHP_E4426b::Erase() { if ((m_StatusCode = Initialize()) != GPIB_SUCCESS) // basically just sends "*RST" return m_StatusCode; m_SaveState = "*SAV %d, %d"; for (int i=0; i < 10; i++) for (int j=0; j < 100; j++) { sprintf(m_CmdString, m_SaveState, j, i); if ((m_StatusCode = Send(m_CmdString, strlen(m_CmdString))) != GPIB_SUCCESS) return m_StatusCode; } return GPIB_SUCCESS; } I tried putting a small Sleep() delay (10-20 ms) at the end of the inner loop, and to my surprise it caused the error to show up earlier rather than later. 10 ms caused the loop to error out at 44,1 and 20 ms was even sooner. I've already eliminated faulty cabling or the instrument as the culprit. This same type of sequence works without any error on a higher end signal generator, so I'm tempted to chalk this up to a bug in the instrument's firmware.

  • OpenGL Polygon Stipple Not Working On Different Machine

    - by FranticPedantic
    I have a situation where I am trying to draw a semi-transparent rectangle over a background that is not using openGL and so I can not use blending. I decided to use polygon stippling for a 'screen door transparency' effect as recommended by some. It works fine on my machine and some others, but on some machines with slightly old Intel graphics cards it's failing to render the rectangle at all. If I turn off polygon stipple, it renders fine (but without the stipple). I have compared many of the state variables that I thought might affect it (see code) between machines and they are all the same, and I get no errors. static const GLubyte stipplePatternChkr[128]; //definition omitted for clarity //but works on my machine // stipple the box glPolygonMode(GL_FRONT_AND_BACK, GL_FILL); glColor4ubv(Color(COLORREF_PADGRAY)); glEnable(GL_POLYGON_STIPPLE); glPolygonStipple(stipplePatternChkr); CRect rcStipple(dim); rcStipple.DeflateRect(padding - 1, padding - 1); glBegin(GL_QUADS); glVertex2i(rcStipple.left, rcStipple.bottom); glVertex2i(rcStipple.right, rcStipple.bottom); glVertex2i(rcStipple.right, rcStipple.top); glVertex2i(rcStipple.left, rcStipple.top); glEnd(); glDisable(GL_POLYGON_STIPPLE); int err = glGetError(); if (err != GL_NO_ERROR) { TRACE("glError(%s: %s)\n", s, gluErrorString(err)); } float x; glGetFloatv(GL_UNPACK_ALIGNMENT, &x); TRACE("unpack alignment %f\n", x); glGetFloatv(GL_UNPACK_IMAGE_HEIGHT, &x); TRACE("unpack height %f\n", x); glGetFloatv(GL_UNPACK_LSB_FIRST, &x); TRACE("unpack lsb %f\n", x); glGetFloatv(GL_UNPACK_ROW_LENGTH, &x); TRACE("unpack length %f\n", x); glGetFloatv(GL_UNPACK_SKIP_PIXELS, &x); TRACE("upnack skip %f\n", x); glGetFloatv(GL_UNPACK_SWAP_BYTES, &x); TRACE("upnack swap %f\n", x);

  • Should I deal with files longer than MAX_PATH?

    - by John
    Just had an interesting case. My software reported back a failure caused by a path being longer than MAX_PATH. The path was just a plain old document in My Documents, e.g.: C:\Documents and Settings\Bill\Some Stupid FOlder Name\A really ridiculously long file thats really very very very..........very long.pdf Total length 269 characters (MAX_PATH==260). The user wasn't using a external hard drive or anything like that. This was a file on an Windows managed drive. So my question is this. Should I care? I'm not saying can I deal with the long paths, I'm asking should I. Yes I'm aware of the "\?\" unicode hack on some Win32 APIs, but it seems this hack is not without risk (as it's changing the behaviour of the way the APIs parse paths) and also isn't supported by all APIs . So anyway, let me just state my position/assertions: First presumably the only way the user was able to break this limit is if the app she used uses the special Unicode hack. It's a PDF file, so maybe the PDF tool she used uses this hack. I tried to reproduce this (by using the unicode hack) and experimented. What I found was that although the file appears in Explorer, I can do nothing with it. I can't open it, I can't choose "Properties" (Windows 7). Other common apps can't open the file (e.g. IE, Firefox, Notepad). Explorer will also not let me create files/dirs which are too long - it just refuses. Ditto for command line tool cmd.exe. So basically, one could look at it this way: a rouge tool has allowed the user to create a file which is not accessible by a lot of Windows (e.g. Explorer). I could take the view that I shouldn't have to deal with this. (As an aside, this isn't an vote of approval for a short max path length: I think 260 chars is a joke, I'm just saying that if Windows shell and some APIs can't handle 260 then why should I?). So, is this a fair view? Should I say "Not my problem"? Thanks! John

  • How to properly test Hibernate length restriction?

    - by Cesar
    I have a POJO mapped with Hibernate for persistence. In my mapping I specify the following: <class name="ExpertiseArea"> <id name="id" type="string"> <generator class="assigned" /> </id> <version name="version" column="VERSION" unsaved-value="null" /> <property name="name" type="string" unique="true" not-null="true" length="100" /> ... </class> And I want to test that if I set a name longer than 100 characters, the change won't be persisted. I have a DAO where I save the entity with the following code: public T makePersistent(T entity){ transaction = getSession().beginTransaction(); transaction.begin(); try{ getSession().saveOrUpdate(entity); transaction.commit(); }catch(HibernateException e){ logger.debug(e.getMessage()); transaction.rollback(); } return entity; } Actually the code above is from a GenericDAO which all my DAOs inherit from. Then I created the following test: public void testNameLengthMustBe100orLess(){ ExpertiseArea ea = new ExpertiseArea( "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890" + "1234567890"); assertTrue("Name should be 100 characters long", ea.getName().length() == 100); ead.makePersistent(ea); List<ExpertiseArea> result = ead.findAll(); assertEquals("Size must be 1", result.size(),1); ea.setName(ea.getName()+"1234567890"); ead.makePersistent(ea); ExpertiseArea retrieved = ead.findById(ea.getId(), false); assertTrue("Both objects should be equal", retrieved.equals(ea)); assertTrue("Name should be 100 characters long", (retrieved.getName().length() == 100)); } The object is persisted ok. Then I set a name longer than 100 characters and try to save the changes, which fails: 14:12:14,608 INFO StringType:162 - could not bind value '12345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890' to parameter: 2; data exception: string data, right truncation 14:12:14,611 WARN JDBCExceptionReporter:100 - SQL Error: -3401, SQLState: 22001 14:12:14,611 ERROR JDBCExceptionReporter:101 - data exception: string data, right truncation 14:12:14,614 ERROR AbstractFlushingEventListener:324 - Could not synchronize database state with session org.hibernate.exception.DataException: could not update: [com.exp.model.ExpertiseArea#33BA7E09-3A79-4C9D-888B-4263314076AF] //Stack trace 14:12:14,615 DEBUG GenericDAO:87 - could not update: [com.exp.model.ExpertiseArea#33BA7E09-3A79-4C9D-888B-4263314076AF] 14:12:14,616 DEBUG JDBCTransaction:186 - rollback 14:12:14,616 DEBUG JDBCTransaction:197 - rolled back JDBC Connection That's expected behavior. However when I retrieve the persisted object to check if its name is still 100 characters long, the test fails. The way I see it, the retrieved object should have a name that is 100 characters long, given that the attempted update failed. The last assertion fails because the name is 110 characters long now, as if the ea instance was indeed updated. What am I doing wrong here?

  • Python/Biophysics- Trying to code a simple stochastic simulation!

    - by user359597
    Hey guys- I'm trying to figure out what to make of the following code- this is not the clear, intuitive python I've been learning. Was it written in C or something then wrapped in a python fxn? The code I wrote (not shown) is using the same math, but I couldn't figure out how to write a conditional loop. If anyone could explain/decipher/clean this up, I'd be really appreciative. I mean- is this 'good' python- or does it look funky? I'm brand new to this- but it's like the order of the fxns is messed up? I understand Gillespie's- I've successfully coded several simpler simulations. So in a nutshell- good code-(pythonic)? order? c? improvements? am i being an idiot? The code shown is the 'answer,' to the following question from a biophysics text (petri-net not shown and honestly not necessary to understand problem): "In a programming language of your choice, implement Gillespie’s First Reaction Algorithm to study the temporal behaviour of the reaction A---B in which the transition from A to B can only take place if another compound, C, is present, and where C dynamically interconverts with D, as modelled in the Petri-net below. Assume that there are 100 molecules of A, 1 of C, and no B or D present at the start of the reaction. Set kAB to 0.1 s-1 and both kCD and kDC to 1.0 s-1. Simulate the behaviour of the system over 100 s." def sim(): # Set the rate constants for all transitions kAB = 0.1 kCD = 1.0 kDC = 1.0 # Set up the initial state A = 100 B = 0 C = 1 D = 0 # Set the start and end times t = 0.0 tEnd = 100.0 print "Time\t", "Transition\t", "A\t", "B\t", "C\t", "D" # Compute the first interval transition, interval = transitionData(A, B, C, D, kAB, kCD, kDC) # Loop until the end time is exceded or no transition can fire any more while t <= tEnd and transition >= 0: print t, '\t', transition, '\t', A, '\t', B, '\t', C, '\t', D t += interval if transition == 0: A -= 1 B += 1 if transition == 1: C -= 1 D += 1 if transition == 2: C += 1 D -= 1 transition, interval = transitionData(A, B, C, D, kAB, kCD, kDC) def transitionData(A, B, C, D, kAB, kCD, kDC): """ Returns nTransition, the number of the firing transition (0: A->B, 1: C->D, 2: D->C), and interval, the interval between the time of the previous transition and that of the current one. """ RAB = kAB * A * C RCD = kCD * C RDC = kDC * D dt = [-1.0, -1.0, -1.0] if RAB > 0.0: dt[0] = -math.log(1.0 - random.random())/RAB if RCD > 0.0: dt[1] = -math.log(1.0 - random.random())/RCD if RDC > 0.0: dt[2] = -math.log(1.0 - random.random())/RDC interval = 1e36 transition = -1 for n in range(len(dt)): if dt[n] > 0.0 and dt[n] < interval: interval = dt[n] transition = n return transition, interval if __name__ == '__main__': sim()

  • Setting UITableViewCell button image values during scrolling

    - by Rob
    I am having an issue where I am trying to save whether a repeat image will show selected or not (it is created as a UIButton on a UITableViewCell created in IB). The issue is that since the cell gets re-used randomly, the image gets reset or set somewhere else after you start scrolling. I've looked all over and the advice was to setup an NSMutableArray to store the button's selection state and I am doing that in an array called checkRepeatState My question is: where do I put the if-then-else statement in the code to where it will actually change the button image based on if the checkRepeatState is set to 0 or 1 for the given cell that is coming back into view? Right now, the if-then-else statement I am using has absolutely no effect on the button image when it comes into view. I'm very confused at this point. Thank you ahead of time for any insight you can give!!! My code is as follows: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { // set up the cell static NSString *CellIdentifier = @"PlayerCell"; PlayerCell *cell = (PlayerCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (!cell) { [[NSBundle mainBundle] loadNibNamed:@"PlayerNibCells" owner:self options:nil]; cell = tmpCell; self.tmpCell = nil; NSLog(@"Creating a new cell"); } // Display dark and light background in alternate rows -- see tableView:willDisplayCell:forRowAtIndexPath:. cell.useDarkBackground = (indexPath.row % 2 == 0); // Configure the data for the cell. NSDictionary *dataItem = [soundCategories objectAtIndex:indexPath.row]; UILabel *label; label = (UILabel *)[cell viewWithTag:1]; label.text = [dataItem objectForKey:@"AnimalName"]; label = (UILabel *)[cell viewWithTag:2]; label.text = [dataItem objectForKey:@"Description"]; UIImageView *img; img = (UIImageView *)[cell viewWithTag:3]; img.image = [UIImage imageNamed:[dataItem objectForKey:@"Icon"]]; NSInteger row = indexPath.row; NSNumber *checkValue = [checkRepeatState objectAtIndex:row]; NSLog(@"checkValue is %d", [checkValue intValue]); // Reusing cell; make sure it has correct image based on checkRepeatState value UIButton *repeatbutton = (UIButton *)[cell viewWithTag:4]; if ([checkValue intValue] == 1) { NSLog(@"repeatbutton is selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeatselected.png"] forState:UIControlStateSelected]; [repeatbutton setNeedsDisplay]; } else { NSLog(@"repeatbutton is NOT selected"); [repeatbutton setImage:[UIImage imageNamed:@"repeat.png"] forState:UIControlStateNormal]; [repeatbutton setNeedsDisplay]; } cell.accessoryType = UITableViewCellAccessoryNone; return cell; }

  • Best Practices / Patterns for Enterprise Protection/Remediation of SSNs (Social Security Numbers)

    - by Erik Neu
    I am interested in hearing about enterprise solutions for SSN handling. (I looked pretty hard for any pre-existing post on SO, including reviewing the terriffic SO automated "Related Questions" list, and did not find anything, so hopefully this is not a repeat.) First, I think it is important to enumerate the reasons systems/databases use SSNs: (note—these are reasons for de facto current state—I understand that many of them are not good reasons) Required for Interaction with External Entities. This is the most valid case—where external entities your system interfaces with require an SSN. This would typically be government, tax and financial. SSN is used to ensure system-wide uniqueness. SSN has become the default foreign key used internally within the enterprise, to perform cross-system joins. SSN is used for user authentication (e.g., log-on) The enterprise solution that seems optimum to me is to create a single SSN repository that is accessed by all applications needing to look up SSN info. This repository substitutes a globally unique, random 9-digit number (ASN) for the true SSN. I see many benefits to this approach. First of all, it is obviously highly backwards-compatible—all your systems "just" have to go through a major, synchronized, one-time data-cleansing exercise, where they replace the real SSN with the alternate ASN. Also, it is centralized, so it minimizes the scope for inspection and compliance. (Obviously, as a negative, it also creates a single point of failure.) This approach would solve issues 2 and 3, without ever requiring lookups to get the real SSN. For issue #1, authorized systems could provide an ASN, and be returned the real SSN. This would of course be done over secure connections, and the requesting systems would never persist the full SSN. Also, if the requesting system only needs the last 4 digits of the SSN, then that is all that would ever be passed. Issue #4 could be handled the same way as issue #1, though obviously the best thing would be to move away from having users supply an SSN for log-on. There are a couple of papers on this: UC Berkely: http://bit.ly/bdZPjQ Oracle Vault: bit.ly/cikbi1

  • .NET JIT Code Cache leaking?

    - by pitchfork
    We have a server component written in .Net 3.5. It runs as service on a Windows Server 2008 Standard Edition. It works great but after some time (days) we notice massive slowdowns and an increased working set. We expected some kind of memory leak and used WinDBG/SOS to analyze dumps of the process. Unfortunately the GC Heap doesn’t show any leak but we noticed that the JIT code heap has grown from 8MB after the start to more than 1GB after a few days. We don’t use any dynamic code generation techniques by our own. We use Linq2SQL which is known for dynamic code generation but we don’t know if it can cause such a problem. The main question is if there is any technique to analyze the dump and check where all this Host Code Heap blocks that are shown in the WinDBG dumps come from? [Update] In the mean time we did some more analysis and had Linq2SQL as probable suspect, especially since we do not use precompiled queries. The following example program creates exactly the same behaviour where more and more Host Code Heap blocks are created over time. using System; using System.Linq; using System.Threading; namespace LinqStressTest { class Program { static void Main(string[] args) { for (int i = 0; i < 100; ++ i) ThreadPool.QueueUserWorkItem(Worker); while(runs < 1000000) { Thread.Sleep(5000); } } static void Worker(object state) { for (int i = 0; i < 50; ++i) { using (var ctx = new DataClasses1DataContext()) { long id = rnd.Next(); var x = ctx.AccountNucleusInfos.Where(an => an.Account.SimPlayers.First().Id == id).SingleOrDefault(); } } var localruns = Interlocked.Add(ref runs, 1); System.Console.WriteLine("Action: " + localruns); ThreadPool.QueueUserWorkItem(Worker); } static Random rnd = new Random(); static long runs = 0; } } When we replace the Linq query with a precompiled one, the problem seems to disappear.

  • [NSIS] Custom radio-buttom INI page via Eclipse

    - by Omegazero
    I'm using Eclipse's create InstallOptions menu to create a custom INI page with radio-buttons for repackaging the Blackberry Desktop installer. There are 2 sections for each type: "Internet" and "Enterprise". I need a user to select 1 of the 2 options and depending on their selection, the page will carry over the selection chosen in the custom page, jump to the INSTFILES page, and continue onto the end. I couldn't find any concrete documentation on getting INI pages to load in the script (I'm probably searching incorrectly), and then pass data from one page to the next (according to fields I guess?) Any help is appreciated. Even if it's to tell me I'm blind and can't read a doc (though a link would help :) ) Here's the INI code: ; Auto-generated by EclipseNSIS InstallOptions Script Wizard ; Jul 29, 2009 5:42:56 PM [Settings] NumFields=7 Title=RIM BlackBerry Desktop 5.0 installation CancelEnabled=1 [Field 1] Type=RadioButton Left=15 Top=28 Right=100 Bottom=38 Text=Internet State= Flags=NOTIFY [Field 4] Type=RadioButton Left=15 Top=95 Right=100 Bottom=105 Text=Enterprise Flags=NOTIFY [Field 2] Type=GroupBox Left=0 Top=10 Right=300 Bottom=75 Text= [Field 5] Type=Label Left=30 Top=42 Right=235 Bottom=52 Text=For users who are NOT on the Enterprise (Exchange) server [Field 6] Type=Label Left=30 Top=111 Right=235 Bottom=121 Text=Choose this only if you are on the Exchange server [Field 3] Type=GroupBox Left=0 Top=75 Right=300 Bottom=140 [Field 7] Type=Label Left=0 Top=0 Right=130 Bottom=10 Text=Please choose your installation method ...And here's the NSI code: Auto-generated by EclipseNSIS Script Wizard Jul 29, 2009 5:42:16 PM Name "BlackBerry Desktop" RequestExecutionLevel admin General Symbol Definitions !define VERSION 5.0.0.11 !define COMPANY RIM !define URL http://www.blackberry.com MUI Symbol Definitions !define MUI_ICON BBD.ico !define MUI_LICENSEPAGE_RADIOBUTTONS Included files !include Sections.nsh !include MUI2.nsh Reserved Files ReserveFile "${NSISDIR}\Plugins\AdvSplash.dll" Installer pages !insertmacro MUI_PAGE_WELCOME !insertmacro MUI_PAGE_LICENSE license.txt !insertmacro MUI_PAGE_COMPONENTS !insertmacro MUI_PAGE_INSTFILES !insertmacro MUI_PAGE_FINISH Installer languages !insertmacro MUI_LANGUAGE English Installer attributes OutFile RIM_BlackBerry_Desktop_5.0.exe InstallDir "$TEMP\RIM BlackBerry Desktop 5.0 Setup Files" CRCCheck on XPStyle on ShowInstDetails hide VIProductVersion 5.0.0.11 VIAddVersionKey /LANG=${LANG_ENGLISH} ProductName "BlackBerry Desktop" VIAddVersionKey /LANG=${LANG_ENGLISH} ProductVersion "${VERSION}" VIAddVersionKey /LANG=${LANG_ENGLISH} CompanyName "${COMPANY}" VIAddVersionKey /LANG=${LANG_ENGLISH} CompanyWebsite "${URL}" VIAddVersionKey /LANG=${LANG_ENGLISH} FileVersion "${VERSION}" VIAddVersionKey /LANG=${LANG_ENGLISH} FileDescription "" VIAddVersionKey /LANG=${LANG_ENGLISH} LegalCopyright "" Installer sections Section /o Main SEC0000 SetOutPath $INSTDIR SetOverwrite ifdiff ; TESTING PHASE SectionEnd SectionGroup /e "BlackBerry Desktop Section" Section /o Internet SEC0001 SetOutPath $INSTDIR\DRIVERS SetOverwrite ifdiff ; Execwait 'msiexec /i "$INSTDIR\BlackBerry USB and Modem Drivers_ENG (DM5.0b28).msi" /passive' SetOutPath $INSTDIR SetOverwrite ifdiff ; File /r * ; ExecWait '"$INSTDIR\Setup.exe" /S/v/qb!'
