• How to configure citrix presentation server 4.5 login config

  - by Cory

  Hello, I am a little confused as to something my Citrix Server has been doing. When I login to the web login, (username, password, domain); everything logs in ok and I see all the available application. The problem that I was trying to fix is that when I try to start an application, it asks me to login again to the server that is hosting the citrix server. So, is there anyway to have the initial login credentials pass-through to the server login or skip the server login completely? Side note - I do have pass-through authentication enabled on both my internal and external Citrix site. Thanks for the help! Cory

• Expression blend for WPF 4 release date

  - by OffApps Cory

  I understand that Visual Studio 2010 is being released 12 April, but does anyone know when Expression Blend for .NET and WPF 4 is being released? I have the beta, but it is pretty buggy and it crashes a lot. I have not had much luck searching for the release date, so any help would put my mind at ease. Cory

• Entity Framework Many-To-Many with additional field on Joining Table

  - by Cory G

  I have an entity context that includes three tables (see diagram here). The first is a table that contain products, the second contains recipes. The joining table has fields for IDs in both the products and recipes table as well as a 'bit' field called 'featured'. I've searched and found no example on how to insert only how to select against this type of scenario.Does anyone have any suggestions on how this can be done? Thanks in advance for any help. Cory

• I need to take an array of three lines in a text file and sort them base on the first line in Java.

  - by Cory

  I need to take an array of three lines in a text file and sort them base on the first line in Java. I also need to manipulate this as well and then print to screen. I have a test file that is formatted like this: 10 Michael Jackson 12 Richard Woolsey I need to input this from a text file and then rearrange it based on the number associated with the name. At that point, I need to use a random number generator and assign a variable based on the random number to each name. Then I need to print to screen the variable I added and the name in a different format. Here is an example of the output: 12: Woolsey, Richard Variable assigned 10: Jackson, Michael Other variable assigned I highly appreciate any help. I ask because I do not really know how to input the three lines as one variable and then manipulate later on in the program. Thanks, Cory

• EntityFramework EntityState and databinding along with INotifyPropertyChanged

  - by OffApps Cory

  Hello, all! I have a WPF view that displays a Shipment entity. I have a textblock that contains an asterisk which will alert a user that the record is changed but unsaved. I originally hoped to bind the visibility of this (with converter) to the Shipment.EntityState property. If value = EntityState.Modified Then Return Visibility.Visible Else Return Visibility.Collapsed End If The property gets updated just fine, but the view is ignorant of the change. What I need to know is, how can I get the UI to receive notification of the property change. If this cannot be done, is there a good way of writing my own IsDirty property that handles editing retractions (i.e. if I change the value of a property, then change it back to it's original it does not get counted as an edit, and state remains Unchanged). Any help, as always, will be greatly appreciated. Cory

• First Letter Section Headers with Core Data

  - by Cory Imdieke

  I'm trying to create a list of people sorted in a tableView of sections with the first letter as the title for each section - a la Address Book. I've got it all working, though there is a bit of an issue with the sort order. Here is the way I'm doing it now: NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:[NSEntityDescription entityForName:@"Contact" inManagedObjectContext:context]]; NSSortDescriptor *fullName = [[NSSortDescriptor alloc] initWithKey:@"fullName" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:fullName, nil]; [request setSortDescriptors:sortDescriptors]; [fullName release]; [sortDescriptors release]; NSError *error = nil; [resultController release]; resultController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:context sectionNameKeyPath:@"firstLetter" cacheName:nil]; [resultController performFetch:&error]; [request release]; fullName is a standard property, and firstLetter is a transient property which returns - as you'd expect - the first letter of the fullName. 95% of the time, this works perfectly. The problem is the result controller expects these two "lists" (the sorted fullName list and the sorted firstLetter list) to match exactly. If I have 2 contacts like John and Jack, my fullName list would sort these as Jack, John every time but my firstLetter list might sort them as John, Jack sometimes as it's only sorting by the first letter and leaving the rest to chance. When these lists don't match up, I get a blank tableView with 0 items in it. I'm not really sure how I should go about fixing this issue, but it's very frustrating. Has anyone else run into this? What did you guys find out?

• How to do a natural sort on an NSArray?

  - by Cory Imdieke

  I've got an array of objects, and I need them sorted by their "title" key. It's currently working, though it's using an ASCII sort instead of a natural sort. The titles are filenames, so they look like this: file1 file2 file3 ... file10 file11 file12 I'm getting, as you would expect: file1 file10 file11 file12 file2 file3 ... Does anyone know if there is a way built-in to the NSArray sorting functionality to get this natural sorting as opposed to the alphabetical sort? I found some generic algorithms, but I was hoping for something built-in...

• Save NSCache Contents to Disk

  - by Cory Imdieke

  I'm writing an app that needs to keep an in-memory cache of a bunch of objects, but that doesn't get out of hand so I'm planning on using NSCache to store it all. Looks like it will take care of purging and such for me, which is fantastic. I'd also like to persist the cache between launches, so I need to write the cache data to disk. Is there an easy way to save the NSCache contents to a plist or something? Are there perhaps better ways to accomplish this using something other than NSCache? This app will be on the iPhone, so I'll need only classes that are available in iOS 4+ and not just OS X. Thanks!

• Visual Studio 2008 doesn't create *.refresh files for external DLL references... what am I missing?

  - by Cory Larson

  Hi all-- I've got a question about something that's just been irritating me. A colleague and I are building a support framework for our current client that we want to reference in other projects. The DLL we want as a reference in our project would be an external reference. We're adding it by doing "Add Reference...", then browsing to the location of the .dll. What I want Visual Studio to do is only add the .xml, .pdb, and a .dll.refresh file, but instead it copies the actual .dll (and .xml and .pdb) into the bin. When we rebuild the framework project, the other project that uses its .dll gets all out of whack until we drop and re-add the reference. Everything I've read online says that VS2008 is supposed to create the .dll.refresh files for you, but it never does. Any ideas? Am I missing something or doing something wrong? At this point I'm ready to add a pre-build event to simply copy the framework .dll into my bin, but the .refresh file seems like less of a hassle if it would just work. Thanks, Cory

• LINQ to Entities exceptions (ElementAtOrDefault and CompareObjectEqual)

  - by OffApps Cory

  I am working on a shipping platform which will eventually automate shipping through several major carriers. I have a ShipmentsView Usercontrol which displayes a list of Shipments (returned by EntityFramework), and when a user clicks on a shipment item, it spawns a ShipmentEditView and passes the ShipmentID (RecordKey) to that view. I initially wrestled with trying to get the context from the parent (ShipmentsView) and finally gave up resolving to get to it later. I wanted to do this to keep a single instance of the context. anyhow, I now create a new instance of the context in my ShipmentEditViewModel, and query against it for the Shipment record. I know I could just pass the record, but I wanted to use the Ocean Framework that Karl Shifflett wrote and don't want to muck about writing new transition methods. So anyhow, I query and when stepping through, I can see that it returns a record, as soon as execution reached the point where it assigned the query result to the e.Result property, it throws up the following exception depending on the query I used. LINQToEntities Dim RecordID As Decimal = CDec(e.Argument) Dim myResult = From ship In _Context.Shipment _ Where ship.ShipID = e.Argument _ Select ship Select Case myResult.Count Case 0 e.Result = New Shipment Case 1 e.Result = myResult(0) Case Else e.Result = Nothing End Select "LINQ to Entities does not recognize the method 'System.Object.CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression. LINQToEntities via Method calls Dim RecordID As Decimal = CDec(e.Argument) Dim myResult = _Context.Shipment.Where(Function(s) s.ShipID = RecordID) Select Case myResult.Count Case 0 e.Result = New Shipment Case 1 e.Result = myResult(0) Case Else e.Result = Nothing End Select LINQ to Entities does not recognize the method 'SnazzyShippingDAL.Shipment ElementAtOrDefault[Shipment] (System.Linq.IQueryable`1[SnazzyShippingDAL.Shipment], Int32)' method, and this method cannot be translated into a store expression. I have been trying to get this thing to display a record for like three days. i am seriously thinking about going back and re=-engineering it without the MVVM pattern (which I realize I am only starting to learn and understand) if only to make the &$^%ed thing work. Any help will be muchly appreciated. Cory

• New to MVVM - Best practices for seperating Data processing thread and UI Thread?

  - by OffApps Cory

  Good day. I have started messing around with the MVVP pattern, and I am having some problems with UI responsiveness versus data processing. I have a program that tracks packages. Shipment and package entities are persisted in SQL database, and are displayed in a WPF view. Upon initial retrieval of the records, there is a noticeable pause before displaying the new shipments view, and I have not even implemented the code that counts shipments that are overdue/active yet (which will necessitate a tracking check via web service, and a lot of time). I have built this with the Ocean framework, and all appears to be doing well, except when I first started my foray into multi-threading. It broke, and it appeared to break something in Ocean... Here is what I did: Private QueryThread As New System.Threading.Thread(AddressOf GetShipments) Public Sub New() ' Insert code required on object creation below this point. Me.New(ViewManagerService.CreateInstance, ViewModelUIService.CreateInstance) 'Perform initial query of shipments 'QueryThread.Start() GetShipments() Console.WriteLine(Me.Shipments.Count) End Sub Public Sub New(ByVal objIViewManagerService As IViewManagerService, ByVal objIViewModelUIService As IViewModelUIService) MyBase.New(objIViewModelUIService) End Sub Public Sub GetShipments() Dim InitialResults = From shipment In db.Shipment.Include("Packages") _ Select shipment Me.Shipments = New ShipmentsCollection(InitialResults, db) End Sub So I declared a new Thread, assigned it the GetShipments method and instanced it in the default constructor. Ocean freaks out at this, so there must be a better way of doing it. I have not had the chance to figure out the usage of the SQL ORM thing in Ocean so I am using Entity Framework (perhaps one of these days i will look at NHibernate or something too). Any information would be greatly appreciated. I have looked at a number of articles and they all have examples of simple uses. Some have mentioned the Dispatcher, but none really go very far into how it is used. Anyone know any good tutorials? Cory

• Data validation best practices: how can I better construct user feedback?

  - by Cory Larson

  Data validation, whether it be domain object, form, or any other type of input validation, could theoretically be part of any development effort, no matter its size or complexity. I sometimes find myself writing informational or error messages that might seem harsh or demanding to unsuspecting users, and frankly I feel like there must be a better way to describe the validation problem to the user. I know that this topic is subjective and argumentative. I've migrated this question from StackOverflow where I originally asked it with little response. Basically, I'm looking for good resources on data validation and user feedback that results from it at a theoretical level. Topics and questions I'm interested in are: Content Should I be describing what the user did correctly or incorrectly, or simply what was expected? How much detail can the user read before they get annoyed? (e.g. Is "Username cannot exceed 20 characters." enough, or should it be described more fully, such as "The username cannot be empty, and must be at least 6 characters but cannot exceed 30 characters."?) Grammar How do I decide between phrases like "must not," "may not," or "cannot"? Delivery This can depend on the project, but how should the information be delivered to the user? Should it be obtrusive (e.g. JavaScript alerts) or friendly? Should they be displayed prominently? Immediately (i.e. without confirmation steps, etc.)? Logging Do you bother logging validation errors? Internationalization Some cultures prefer or better understand directness over subtlety and vice-versa (e.g. "Don't do that!" vs. "Please check what you've done."). How do I cater to the majority of users? I may edit this list as I think more about the topic, but I'm genuinely interested in proper user feedback techniques. I'm looking for things like research results, poll results, etc. I've developed and refined my own techniques over the years that users seem to be okay with, but I work in an environment where the users prefer to adapt to what you give them over speaking up about things they don't like. I'm interested in hearing your experiences in addition to any resources to which you may be able to point me.

• Is there a solution for SugarCRM that can map roles or privileges to Active Directory groups?

  - by Cory Larson

  We're presenting SugarCRM as an option to one of our clients, but they want to drive permissions within Sugar by users' AD groups. Current LDAP integration with SugarCRM only does password management. Does anybody know of a plug-in that supports this? I've searched and have not been able to find anything. Has anybody change the LDAP module code within Sugar to accommodate these features? I'd be interested in chatting with you. I apologize if this isn't on the correct site; neither serverfault nor stackoverflow seemed like the correct place. Perhaps webapps? Thanks!

• How can I hard reset a USB device?

  - by Cory

  I have a USB device (a modem) that is really finicky. Sometimes it works fine, but other times it refuses to connect. The only solution I have found to fix it once it gets into a bad state is to physically unplug the device and plug it back in. However, I don't always have physical access to the machine it is plugged in on, so I'm looking for a way to do this through the command line. This post suggests running: sudo modprobe -w -r usb_storage; sudo modprobe usb_storage However I get an "unknown option -w" output. This slightly modified command: sudo modprobe -r usb_storage Fails with the message FATAL: Module usb_storage is in use. If I try to kill -9 the processes marked [usb-storage] before running they refuse to die (I think because they are deeply tied to the kernel). Anyone know of a way to do this? NOTE: I cross-posted this on superuser.com as I didn't know which was more appropriate. I will delete and/or link whichever one is answered first.

• SEP Search Engine Placement

  - by Cory Baumer

  My employer was recently contacted by a company who convinced my employer that they could do what they called search engine placement and that they can guaranty that we will be placed on he top of googles search results. I immediately told my employer that it sounded like a scam, but I was made to contact the company regardless and investigate. The sales person insisted that SEP was different than the SEO and ad words campaigns we are already performing and that it was a cheaper way to be listed in the adwords section and that it didn't include a cost per click. It sounds to me like its kinda scammy like they are going to setup an adwords campaign and just charge us a flat rate that is higher than the cost per clicks. Has anyone heard of this and is it at all legitimate?

• SQL Server 2008 to Sybase Linked Server (x64) -- Provider and permissions issues

  - by Cory Larson

  Good morning, We're testing a new SQL Server 2008 setup (64-bit) and one of our requirements was to get a linked server up and talking to a Sybase database. We've successfully done so using Sybase's 64-bit 15.5 drivers, however I can't expand the catalog list from a remote machine (connecting to the '08 box with SSMS) without having my network account being added as an Administrator on the actual box and then using Windows Authentication to connect to the server instance. This is going to be problematic when we go live. Has anybody experienced this, or have any input on the permissions in SQL Server 2008 with regards to linked servers? If I remove my network account from the Administrators group, the big error I'm getting is a 'Msg 7302, Level 16, State 1, Line 41' with a description something like "Cannot create an instance of OLE DB provider "ASEOLEDB" for linked server "", and all research points to permissions issues. Thoughts? This document talks about DCOM configuration and permissions, but we've tried all of it with no luck. Thanks

• AppArmor Profile for PowerDNS

  - by Cory J

  I am currently working on a new authoritative nameserver using powerdns on Ubuntu 8.04 LTS. I'd like to have AppArmor protecting this service like it did with bind, but when I look in /etc/apparmor.d/, there was no AppArmor profile for this service installed by default. Any experienced pdns admins know what all files pdns accesses, so I can define a profile? Or better yet, does anyone HAVE a profile for pdns? Many thanks for any suggestions.

• Ntop monitoring - Hosts visible with no SPAN/mirroring

  - by Cory J

  I am attempting to use ntop to monitor traffic over a Cisco Catalyst switch. I was assuming that in order to see any of the traffic, I'd have to use monitor, as described here: http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml. Howver, before I did anything on the switch, I simply plugged my ntop server in and fired up ntop. To my suprise, I instantly see 3+ pages of hosts, and thousands of packets. How is ntop seeing this? I have verified that no monitoring exists on the switch (run as en): cs1.pvdc#show monitor No SPAN configuration is present in the system. My ntop server is Ubuntu 8.04, I haven't done ANY configuration, I just installed the ntop package. This is also a fresh Ubuntu install. Is there anything else on my switch besides "monitor" that might cause my switch to mirror all its traffic like this? I've tried plugging ntop into different ports with the same results. UPDATE: It appears to be more then just broadcast traffic showing up in ntop, for example, I can see when my IPs have talked to the DNS server or generated HTTP traffic. If my switch is misconfigured, can anyone point me in the right direction towards rectify this? Not a Cisco expert.

• Throughput tool with decent graphing.

  - by Cory J

  I've been looking through some of the tools available for measuring network throughput, namely iperf, bwping, ttcp, etc. I am planning on doing throughput tests over a long period of time, so what I really need is good graphing output, preferably rrd graphs. The Jperf frontend for iperf will generate a graph, and bmon has a nice command-line graph, but these simply count seconds since the test was started. I am trying to measure trends in throughput over times of the day, so a graph with times and days is necessary. So a way to get iperf to log to RRDs would be best, if this isn't possible could someone point me toward another solution?

• After using lvextend, I can't recover unused space

  - by Cory Gagliardi

  I needed to add more disk space to my CentOS VM, so I added another virtual disk, then used lvextend to add the space to the existing partition. The steps I followed was: echo "- - -" > /sys/class/scsi_host/host0/scan pvcreate /dev/sdb vgextend VolGroup00 /dev/sdb lvextend -l +100%FREE /dev/VolGroup00/LogVol00 resize2fs /dev/VolGroup00/LogVol00 This worked fine. I subsequently filled up the VM, then deleted most of the used disk space. However, the unused disk space was never recovered after I deleted all of the files. This will illustrate what I'm saying better: # df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 61G 32G 26G 56% / /dev/sda1 99M 20M 75M 21% /boot tmpfs 1006M 0 1006M 0% /dev/shm # pwd; du -h --max-depth=0 / 5.1G . I cannot figure out how to get the partition to see that only 5.1 GB is used. Any ideas what I'm doing wrong?
