  • Outlook 2010 + Move IMAP PST file = Outlook data file cannot be accessed

    - by GWB
    I set up a new IMAP account in Outlook 2010. It works but creates IMAP PST file in C:\Users\User\AppData\Local\Microsoft\Outlook. I want the file on my data drive in D:\Users\User\Documents\Outlook Files (the same folder where outlook automatically creates the local Outlook PST. I followed the instructions here to move the IMAP PST. Testing the account (send/receive) works fine, but if I try to manually send an email I get error 0x8004010F Outlook data file cannot be accessed. I've tried repairing the PST using SCANPST (it always finds errors), and deleting and recreating the account but I get the same error. If I move the PST file back, it works again, but this is not ideal. Note: I don't think this is a duplicate of this question as the cause is different and the solution does not help.

  • Sign out of messenger on Windows 8

    - by jmlumpkin
    I just installed the Windows 8 Consumer Preview. Just going through the default procedure, I let it use my Xbox Live account to create a user. When I then went and turned on my Xbox, it now notified me that I was logged into Messenger in two locations. I went back to Windows 8, and turned my Live account into a local account on that machine. But when I then turned the Xbox again, I got the same message. Is there a way to just 'sign out of messenger' on Windows 8? Or is there a location to even see where I am signed in at?

  • I can access my company mail on iPhone, but not on a PC/Mac

    - by Philippe
    On my iPhone (4), I can set up my company e-mail, which allows me to receive and send e-mail and use the calender to manage appointments. The company is using Exchange 2003. The problem is that this is the only way I can access my e-mail when I'm not at the office. I've tried setting up an account on Outlook 2007, Outlook 2010, Outlook 2011 (Mac) and the OSX Mail app, but it doesn't work. The server cannot be reached, even though I've used the exact same settings as on the iPhone. The info I use on the iPhone is: Server name of the company mail server (it's the same as for webmail) Use SSL AD Domain of my account My AD account name Password When I enter this on the iPhone, it works like a charm, but whatever I try on one of my desktops, it doesn't work. FYI: I can't ask the company IT guys because according to them, it doesn't work from a remote location, not even on the iPhone (but obviously, that works just fine)

  • Get-Mailbox not returning all mailboxes

    - by rotard
    I am trying to set up an exchange mailbox backup job with Vembu Storegrid and StoreGrid is unable to list the mailboxes for the client. While I was troubleshooting the issue, I did notice another thing: running the Get-Mailbox command on the mail server as the backup user only shows the mailbox for that account, while running Get-Mailbox as my admin account returns a list of what appears to be all the mailboxes. My service account is a member of "Administrators", "Domain Admins", and "Domain Users". What additional permissions might be required to list all mailboxes in the system?

  • What do user accounts do?

    - by Fasih Khatib
    Ok, this is my first time with windows server os. I started doing this out of curiosity. I have a desktop running windows server os 2003 which is connected to a wifi router. I have a laptop that connects to this router wirelessly and THIS REPRESENTS A REMOTE USER. I want to provide access to this user to a set of files ON THE SERVER. So i create an account for this user, as Start - programs - admin tools -user manager and then the steps to create an account. When i use this laptop, i log in as administrator as its the default account that came. Now when i want this laptop to be the user i just created on the server, HOW DO I DO THAT?

  • AD Local Admins without password sharing

    - by Cocoabean
    My team is building out an Active Directory environment in a small grad school with support for general computer labs, and staff/faculty machine and account management. We have a team of student consultants that are hired to do general help desk work. As of now we have a local admin account on every machine. It has the same password and all of us know it. I know it's not best practice and I want to avoid this with the new setup. We want to have local admin accounts in case there are network issues that prevent AD authentication, but we do not want this account to be generic with a shared password. Is there a way we can get each machine to cache the necessary information to authenticate a group of local admins so that if AD is somehow inaccessible, student consultants can still login with their AD admin accounts?

  • Giving SSH access to a user, and security issues.

    - by Kris Sauquillo
    Okay, so I have a VPS and I made an account for a friend so he can host his own domains (using the reseller features in DirectAdmin). He's asking for SSH access, and I know that this is probably a bad idea. Does he have access to my whole server, such as executing commands, accessing my domains that I host on my server? I logged into my SSH using his account details and it let me navigate around all of the root folders/files, and his account is under /home/AccountName/. Is there anyway to restrict his access to his folder only? And the commands he can use?

  • Postfix smarthost with diffent relayhosts and sender dependant authentication

    - by mattinsalto
    I've setup postfix as smarthost with different relayhosts and sender dependant authentication. Everything works ok, but I have a performance question. Is it better to send all the email corresponding to a domain through only one account? I mean, now I'm sending each message authenticating to the relay host with the sender credentials. Example: If I have 5 email accounts and I send 10 simultaneous messages from each account, How many times is postfix login to the relay host if I have sender dependant authentication? 5 times? once for each sender 50 times? once for each message If I send all the messages corresponding to one realy host through one account, how many times does postfix login to the relay host? only once? Thanks in advance.

  • Do all domains on the same shared hosting server have the same IP or ID

    - by silow
    Here's what I've got: siteA.com and siteB.com are hosted on hostgator. They're hosted on the same account of a shared hosting server (not VPS or dedicated). script.php is an external site that each of these 2 sites are accessing. I noticed that when siteA.com or siteB.com access the outside script.php, the script identifies them both as 1a.12.12ab.static.theplanet.com (apparently because hostgator uses theplanet.com servers). The fact that they're identified as the same value isn't surprising because after all they're hosted on the same account /home/user123/public_html. What I'm wondering about is how about other websites that are hosted on the same shared hosting server, but under other accounts. Basically other websites that are under another developer's control, but just happen to share the same hardware (hosting server). Do they also have the exact same identifier 1a.12.12ab.static.theplanet.com or that changes by account?

  • RedirectPermanent vs RewriteRule [R]

    - by notbrain
    I currently have a perm_redirects.conf file that gets included into my apache config stack where I have lines in the format RedirectPermanent /old/url/path /new/url/path It looks like I'm required to use an absolute URL for the new path, e.g.: http://example.com/new/url/path. In the logs I'm getting "incomplete redirect target /new/url/path was corrected to http://example.com/new/url/path." (paraphrased). In the 2.2 docs for RewriteRule, at the bottom they show the following as being a valid redirect, with only the url-paths instead of an abs URL for the right hand side of the redirect: RewriteRule ^/old/url/path(.*) /new/url/path$1 [R] But I can't seem to get that format to work to replicate the functionality of the RedirectPermanent version. Is this possible?

  • Server 2008 R2 file access permissions

    - by Napster100
    I'm finding it awkward to sort out permissions for file sharing and access on my LAN. I've created an account on the server node (as a normal user) and shared a drive that has 2 folders at the root, one is for personal file storage and the other shared files, if I connect to the shared area from a workstation running windows 7 and log-in using the account I created on the server, I can look through directories but can't look in some (which I wanted as I changed the permissions for that to happen), but my problem is although the permissions are set for this user account to have full control of the specific folder I can't create a folder in that area or upload files to that folder. Could someone explain why this is? Thanks in advanced

  • What does the red x icon mean next to a user in folder permissions (Windows 7)

    - by Scott Szretter
    In trying to debug various strange issues on a machine, I found something strange - when I go to C:\Users\administrator and get properties, security tab, it lists the users (the local admin account, system, and 'administrator' which is the domain administrator account). It all looks fine in terms of permissions (full control, etc.) compared to other machines. The one difference is there is a small red circle with an X to the left of the user icon/name. Additionally, there are various folders where it says access denied under there - for example, my documents! Even logged in as the local machine administrator account (which is not named administrator), I am unable to change the permissions - it says access denied. Any ideas what this means and how to fix it? I even tried re-joining the machine to the domain.

  • Run BGInfo At Startup For All Users

    - by slickboy
    I have a Windows 7 image which I intend to deploy across a business. For simplicity I intend to install BGInfo on each machine and have it update each time a user logs in. From what I can see, when BGInfo creates a configuration file, the file contains variables which are local to each account - and therefore the configuration file will only work on the user account that created it. Has anyone any idea as to how make these configuration files 'generic' so that BGInfo will work for all accounts when they log in? At present I have the BGInfor application and a BGInfo configuration file saved on the C drive and I have written a batch file which is stored in the 'All Users/Start Menu/Startup' directory (which executes every time any user on the computer logs in), however this only works for the account which created the configuration file. Thanks for any help.

  • How can I move authorized applications between google accounts?

    - by zoopp
    I'm looking into creating an email address with a professional name on gmail and due to the fact that I can't change my current one I have to create new google account. Among some things which which need to be patched (eg. forwarding email to the new address until every other account's email contact address is changed etc.) I came across authorized applications. If I am to use exclusively the new email address I have to somehow move my authorized applications as well since if I am to eventually delete my old account I will lose access to my current profiles created by those applications (eg. the stackexchange network, youtube etc). How can this move be accomplished?

  • Why does FIND on Windows 7 give an "Access Denied" error?

    - by rann
    Hi All, I have an administrator account on a Windows 7 x64 machine. It is not THE administrator account, the account is simply a member of the administrators group. The install is default. When the user opens a command prompt it ends up in the users' %HOMEPATH% directory where you'll find various directories like the Documents folder. If the user uses the following (windows) FIND command, an "Access Denied" error occurs: FIND /I "My String" C:\Users\Rann\Documents Access denied - C:\USERS\RANN\DOCUMENTS Using runas or right-clicking on the command prompt to run it as an administrator does not change this behaviour; an administrator-level cmd.exe still gives me the same error. Changing the path to any other directory gives the same error. My question is thus: How is one supposed to use the FIND (and possibly other) commands? What rights are needed?

  • How does this decorator make a call to the 'register' method?

    Hi I might be approaching this all wrong.But please help me to understand. I really want to TDD building wpf application using Moq. I would like to mock the viewmodel. Application Show a list of contacts and when you double click on a contact it shows the contact. Test Moq GetContactsCommand.Test it has been called. Test that you get a list of contacts. Not sure how to mock the viewModel and it's commands can you correct me?

    Suppose I write a library with the following: public class Bar { /* ... */ } public class SomeWeirdClass<T> where T : ??? { public T BarMaker(Bar b) { // ... play with b T t = (T)b return (T) b; } } Later, I expect users to use my library by defining their own types which are convertible to Bar and using the SomeWeirdClass 'factory'. public class Foo { public static explicit operator Foo(Bar f) { return new Bar(); } } public class Demo { public static void demo() { Bar b = new Bar(); SomeWeirdClass<Foo> weird = new SomeWeirdClass<Foo>(); Foo f = weird.BarMaker(b); } } this will compile if i set where T : Foo but the problem is that I don't know about Foo at the library's compile time, and I actually want something more like where T : some class that can be instantiated, given a Bar Is this possible? From my limited knowledge it does not seem to be, but the ingenuity of the .NET framework and its users always surprises me... This may or not be related to the idea of static interface methods - at least, I can see the value in being able to specify the presence of factory methods to create objects (similar to the same way that you can already perform where T : new()) edit: Solution - thanks to Nick and bzIm - For other readers I'll provide a completed solution as I understand it: edit2: This solution requires Foo to expose a public default constructor. For an even stupider better solution that does not require this see the very bottom of this post. public class Bar {} public class SomeWeirdClass<T> where T : IConvertibleFromBar<T>, new() { public T BarMaker(Bar b) { T t = new T(); t.Convert(b); return t; } } public interface IConvertibleFromBar<T> { T Convert(Bar b); } public class Foo : IConvertibleFromBar<Foo> { public static explicit operator Foo(Bar f) { return null; } public Foo Convert(Bar b) { return (Foo) b; } } public class Demo { public static void demo() { Bar b = new Bar(); SomeWeirdClass<Foo> weird = new SomeWeirdClass<Foo>(); Foo f = weird.BarMaker(b); } } edit2: Solution 2: Create a type convertor factory to use: #region library defined code public class Bar {} public class SomeWeirdClass<T, TFactory> where TFactory : IConvertorFactory<Bar, T>, new() { private static TFactory convertor = new TFactory(); public T BarMaker(Bar b) { return convertor.Convert(b); } } public interface IConvertorFactory<TFrom, TTo> { TTo Convert(TFrom from); } #endregion #region user defined code public class BarToFooConvertor : IConvertorFactory<Bar, Foo> { public Foo Convert(Bar from) { return (Foo) from; } } public class Foo { public Foo(int a) {} public static explicit operator Foo(Bar f) { return null; } public Foo Convert(Bar b) { return (Foo) b; } } #endregion public class Demo { public static void demo() { Bar b = new Bar(); SomeWeirdClass<Foo, BarToFooConvertor> weird = new SomeWeirdClass<Foo, BarToFooConvertor>(); Foo f = weird.BarMaker(b); } }

  • c# opennetCF background worker - e.result gives a ObjectDisposedException

    - by ikky
    Hi! I'm new working with background worker in C#. Here is a class, and under it, you will find the instansiation of it, and under there i will define my problem for you: I have the class Drawing: class Drawing { BackgroundWorker bgWorker; ProgressBar progressBar; Panel panelHolder; public Drawing(ref ProgressBar pgbar, ref Panel panelBig) // Progressbar and panelBig as reference { this.panelHolder = panelBig; this.progressBar = pgbar; bgWorker = new BackgroundWorker(); bgWorker.WorkerReportsProgress = true; bgWorker.WorkerSupportsCancellation = true; bgWorker.DoWork += new OpenNETCF.ComponentModel.DoWorkEventHandler(this.bgWorker_DoWork); bgWorker.RunWorkerCompleted += new OpenNETCF.ComponentModel.RunWorkerCompletedEventHandler(this.bgWorker_RunWorkerCompleted); bgWorker.ProgressChanged += new OpenNETCF.ComponentModel.ProgressChangedEventHandler(this.bgWorker_ProgressChanged); } public void createDrawing() { bgWorker.RunWorkerAsync(); } private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { Panel panelContainer = new Panel(); // Adding panels to the panelContainer for(i=0; i<100; i++) { Panel panelSubpanel = new Panel(); // Setting size, color, name etc.... panelContainer.Controls.Add(panelSubpanel); // Adding the subpanel to the panelContainer //Report the progress bgWorker.ReportProgress(0, i); // Reporting number of panels loaded } e.Result = imagePanel; // Send the result(a panel with lots of subpanels) as an argument } private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { this.progressBar.Value = (int)e.UserState; this.progressBar.Update(); } private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { if (e.Error == null) { this.panelHolder = (Panel)e.Result; } else { MessageBox.Show("An error occured, please try again"); } } } Instansiating an object of this class: public partial class Draw: Form { public Draw() { ProgressBar progressBarLoading = new ProgressBar(); // Set lots of properties on progressBarLoading Panel panelBigPanelContainer = new Panel(); Drawing drawer = new Drawing(ref progressBarLoading, ref panelBigPanelContainer); drawer.createDrawing(); // this makes the object start a new thread, loading all the panels into a panel container, while also sending the progress to this progressbar. } } Here is my problem: In the private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) i don't get the e.Result as it should be. When i debug and look at the e.Result, the panel's properties have this exception message: '((System.Windows.Forms.Control)(e.Result)).ClientSize' threw an exception of type 'System.ObjectDisposedException' So the object gets disposed, but "why" is my question, and how can i fix this? I hope someone will answer me, this is making me crazy. Another question i have: Is it allowed to use "ref" with arguments? is it bad programming? Thanks in advance. I have also written how i understand the Background worker below here: This is what i think is the "rules" for background workers: bgWorker.RunWorkerAsync(); => starts a new thread. bgWorker_DoWork cannot reach the main thread without delegates - private void bgWorker_DoWork(object sender, DoWorkEventArgs e) { // The work happens here, this is a thread that is not reachable by the main thread e.Result => This is an argument which can be reached by bgWorker_RunWorkerCompleted() bgWorker.ReportProgress(progressVar); => Reports the progress to the bgWorker_ProgressChanged() } - private void bgWorker_ProgressChanged(object sender, ProgressChangedEventArgs e) { // I get the progress here, and can do stuff to the main thread from here (e.g update a control) this.ProgressBar.Value = e.ProgressPercentage; } - private void bgWorker_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { // This is where the thread is completed. // Here i can get e.Result from the bgWorker thread // From here i can reach controls in my main thread, and use e.Result in my main thread if (e.Error == null) { this.panelTileHolder = (Panel)e.Result; } else { MessageBox.Show("There was an error"); } }

  • Marking multi-level nested forms as "dirty" in Rails

    - by Charles Kihe
    I have a three-level multi-nested form in Rails. The setup is like this: Projects have many Milestones, and Milestones have many Notes. The goal is to have everything editable within the page with JavaScript, where we can add multiple new Milestones to a Project within the page, and add new Notes to new and existing Milestones. Everything works as expected, except that when I add new notes to an existing Milestone (new Milestones work fine when adding notes to them), the new notes won't save unless I edit any of the fields that actually belong to the Milestone to mark the form "dirty"/edited. Is there a way to flag the Milestone so that the new Notes that have been added will save? Edit: sorry, it's hard to paste in all of the code because there's so many parts, but here goes: Models class Project < ActiveRecord::Base has_many :notes, :dependent => :destroy has_many :milestones, :dependent => :destroy accepts_nested_attributes_for :milestones, :allow_destroy => true accepts_nested_attributes_for :notes, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Milestone < ActiveRecord::Base belongs_to :project has_many :notes, :dependent => :destroy accepts_nested_attributes_for :notes, :allow_destroy => true, :allow_destroy => true, :reject_if => proc { |attributes| attributes['content'].blank? } end class Note < ActiveRecord::Base belongs_to :milestone belongs_to :project scope :newest, lambda { |*args| order('created_at DESC').limit(*args.first || 3) } end I'm using an jQuery-based, unobtrusive version of Ryan Bates' combo helper/JS code to get this done. Application Helper def add_fields_for_association(f, association, partial) new_object = f.object.class.reflect_on_association(association).klass.new fields = f.fields_for(association, new_object, :child_index => "new_#{association}") do |builder| render(partial, :f => builder) end end I render the form for the association in a hidden div, and then use the following JavaScript to find it and add it as needed. JavaScript function addFields(link, association, content, func) { var newID = new Date().getTime(); var regexp = new RegExp("new_" + association, "g"); var form = content.replace(regexp, newID); var link = $(link).parent().next().before(form).prev(); if (func) { func.call(); } return link; } I'm guessing the only other relevant piece of code that I can think of would be the create method in the NotesController: def create respond_with(@note = @owner.notes.create(params[:note])) do |format| format.js { render :json => @owner.notes.newest(3).all.to_json } format.html { redirect_to((@milestone ? [@project, @milestone, @note] : [@project, @note]), :notice => 'Note was successfully created.') } end end The @owner ivar is created in the following before filter: def load_milestone @milestone = @project.milestones.find(params[:milestone_id]) if params[:milestone_id] end def determine_owner @owner = load_milestone @owner ||= @project end Thing is, all this seems to work fine, except when I'm adding new notes to existing milestones. The milestone has to be "touched" in order for new notes to save, or else Rails won't pay attention.
