  • Resolution changes when using switch

    - by Edward D
    So, the "real" resolution of my monitor is 1024x768. That's what I'd use on my docked Windows laptop, and what I'd use on my Xubuntu desktop connected directly. When I connect a switch, to switch between the two, however, the ubuntu machine's resolution changes. Everything's still proportional, and it still thinks it's doing 1024x768, but the icons and fonts appear larger. Not 800x600 larger, but still big. When I used Xubuntu Precise, I created an xorg.conf file to set a resolution of 1280x1024 which made it look the way it does without the switch ... as a workaround. When I upgraded to Trusty, I lost this. I tried to re-create it, but doesn't seem to load my file. Ideally, I'd like to correct the original problem, but I'd settle for being able to up the resolution. I searched for a while, and tried to do it, but I'm giving up ... please help me out.

  • Changes to the LINQ-to-StreamInsight Dialect

    - by Roman Schindlauer
    In previous versions of StreamInsight (1.0 through 2.0), CepStream<> represents temporal streams of many varieties: Streams with ‘open’ inputs (e.g., those defined and composed over CepStream<T>.Create(string streamName) Streams with ‘partially bound’ inputs (e.g., those defined and composed over CepStream<T>.Create(Type adapterFactory, …)) Streams with fully bound inputs (e.g., those defined and composed over To*Stream – sequences or DQC) The stream may be embedded (where Server.Create is used) The stream may be remote (where Server.Connect is used) When adding support for new programming primitives in StreamInsight 2.1, we faced a choice: Add a fourth variety (use CepStream<> to represent streams that are bound the new programming model constructs), or introduce a separate type that represents temporal streams in the new user model. We opted for the latter. Introducing a new type has the effect of reducing the number of (confusing) runtime failures due to inappropriate uses of CepStream<> instances in the incorrect context. The new types are: IStreamable<>, which logically represents a temporal stream. IQStreamable<> : IStreamable<>, which represents a queryable temporal stream. Its relationship to IStreamable<> is analogous to the relationship of IQueryable<> to IEnumerable<>. The developer can compose temporal queries over remote stream sources using this type. The syntax of temporal queries composed over IQStreamable<> is mostly consistent with the syntax of our existing CepStream<>-based LINQ provider. However, we have taken the opportunity to refine certain aspects of the language surface. Differences are outlined below. Because 2.1 introduces new types to represent temporal queries, the changes outlined in this post do no impact existing StreamInsight applications using the existing types! SelectMany StreamInsight does not support the SelectMany operator in its usual form (which is analogous to SQL’s “CROSS APPLY” operator): static IEnumerable<R> SelectMany<T, R>(this IEnumerable<T> source, Func<T, IEnumerable<R>> collectionSelector) It instead uses SelectMany as a convenient syntactic representation of an inner join. The parameter to the selector function is thus unavailable. Because the parameter isn’t supported, its type in StreamInsight 1.0 – 2.0 wasn’t carefully scrutinized. Unfortunately, the type chosen for the parameter is nonsensical to LINQ programmers: static CepStream<R> SelectMany<T, R>(this CepStream<T> source, Expression<Func<CepStream<T>, CepStream<R>>> streamSelector) Using Unit as the type for the parameter accurately reflects the StreamInsight’s capabilities: static IQStreamable<R> SelectMany<T, R>(this IQStreamable<T> source, Expression<Func<Unit, IQStreamable<R>>> streamSelector) For queries that succeed – that is, queries that do not reference the stream selector parameter – there is no difference between the code written for the two overloads: from x in xs from y in ys select f(x, y) Top-K The Take operator used in StreamInsight causes confusion for LINQ programmers because it is applied to the (unbounded) stream rather than the (bounded) window, suggesting that the query as a whole will return k rows: (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) The use of SelectMany is also unfortunate in this context because it implies the availability of the window parameter within the remainder of the comprehension. The following compiles but fails at runtime: (from win in xs.SnapshotWindow() from x in win orderby x.A select win).Take(k) The Take operator in 2.1 is applied to the window rather than the stream: Before After (from win in xs.SnapshotWindow() from x in win orderby x.A select x.B).Take(k) from win in xs.SnapshotWindow() from b in     (from x in win     orderby x.A     select x.B).Take(k) select b Multicast We are introducing an explicit multicast operator in order to preserve expression identity, which is important given the semantics about moving code to and from StreamInsight. This also better matches existing LINQ dialects, such as Reactive. This pattern enables expressing multicasting in two ways: Implicit Explicit var ys = from x in xs          where x.A > 1          select x; var zs = from y1 in ys          from y2 in ys.ShiftEventTime(_ => TimeSpan.FromSeconds(1))          select y1 + y2; var ys = from x in xs          where x.A > 1          select x; var zs = ys.Multicast(ys1 =>     from y1 in ys1     from y2 in ys1.ShiftEventTime(_ => TimeSpan.FromSeconds(1))     select y1 + y2; Notice the product translates an expression using implicit multicast into an expression using the explicit multicast operator. The user does not see this translation. Default window policies Only default window policies are supported in the new surface. Other policies can be simulated by using AlterEventLifetime. Before After xs.SnapshotWindow(     WindowInputPolicy.ClipToWindow,     SnapshotWindowInputPolicy.Clip) xs.SnapshotWindow() xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.PointAlignToWindowEnd) xs.TumblingWindow(     TimeSpan.FromSeconds(1)) xs.TumblingWindow(     TimeSpan.FromSeconds(1),     HoppingWindowOutputPolicy.ClipToWindowEnd) Not supported … LeftAntiJoin Representation of LASJ as a correlated sub-query in the LINQ surface is problematic as the StreamInsight engine does not support correlated sub-queries (see discussion of SelectMany). The current syntax requires the introduction of an otherwise unsupported ‘IsEmpty()’ operator. As a result, the pattern is not discoverable and implies capabilities not present in the server. The direct representation of LASJ is used instead: Before After from x in xs where     (from y in ys     where x.A > y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, (x, y) => x.A > y.B) from x in xs where     (from y in ys     where x.A == y.B     select y).IsEmpty() select x xs.LeftAntiJoin(ys, x => x.A, y => y.B) ApplyWithUnion The ApplyWithUnion methods have been deprecated since their signatures are redundant given the standard SelectMany overloads: Before After xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count()) xs.GroupBy(x => x.A).SelectMany(     gs =>     from win in gs.SnapshotWindow()     select win.Count()) xs.GroupBy(x => x.A).ApplyWithUnion(gs => from win in gs.SnapshotWindow() select win.Count(), r => new { r.Key, Count = r.Payload }) from x in xs group x by x.A into gs from win in gs.SnapshotWindow() select new { gs.Key, Count = win.Count() } Alternate UDO syntax The representation of UDOs in the StreamInsight LINQ dialect confuses cardinalities. Based on the semantics of user-defined operators in StreamInsight, one would expect to construct queries in the following form: from win in xs.SnapshotWindow() from y in MyUdo(win) select y Instead, the UDO proxy method is referenced within a projection, and the (many) results returned by the user code are automatically flattened into a stream: from win in xs.SnapshotWindow() select MyUdo(win) The “many-or-one” confusion is exemplified by the following example that compiles but fails at runtime: from win in xs.SnapshotWindow() select MyUdo(win) + win.Count() The above query must fail because the UDO is in fact returning many values per window while the count aggregate is returning one. Original syntax New alternate syntax from win in xs.SnapshotWindow() select win.UdoProxy(1) from win in xs.SnapshotWindow() from y in win.UserDefinedOperator(() => new Udo(1)) select y -or- from win in xs.SnapshotWindow() from y in win.UdoMacro(1) select y Notice that this formulation also sidesteps the dynamic type pitfalls of the existing “proxy method” approach to UDOs, in which the type of the UDO implementation (TInput, TOuput) and the type of its constructor arguments (TConfig) need to align in a precise and non-obvious way with the argument and return types for the corresponding proxy method. UDSO syntax UDSO currently leverages the DataContractSerializer to clone initial state for logical instances of the user operator. Initial state will instead be described by an expression in the new LINQ surface. Before After xs.Scan(new Udso()) xs.Scan(() => new Udso()) Name changes ShiftEventTime => AlterEventStartTime: The alter event lifetime overload taking a new start time value has been renamed. CountByStartTimeWindow => CountWindow

  • Triggering Data Changes in N-Tier

    - by Ryan Kinal
    I've been studying n-tier architectures as of late, particularly in VB.NET with Entity Framework and/or LINQ to SQL. I understand the basic concepts, but have been wondering about best practices in regard to triggering CRUD-type operations from user input/action. So, the arcitecture looks something like the following: [presentation layer] - [business layer] - [data layer] - (database) Getting information from the database into the presentation layer is simple and abstracted. It's just a matter of instantiating a new object from the business layer, which in turn uses the data layer to get at the correct information. However, saving (updating and inserting), and deleting seem to require particular APIs on the relevant business objects. I have to assume this is standard practice, unless a business object will save itself on various operations (which seems inefficient), or on disposal (which seems like it just wouldn't work, or may be unwieldy and unreliable). Should my "savable" business objects all implement a particular "ISavable" or "IDatabaseObject" interface? Is this a recognized (anti-)pattern? Are there other, better patterns I should be using that I'm just unaware of? The TLDR question, I suppose, is How does the presentation layer trigger database changes?

  • Why not commit unresolved changes?

    - by Explosion Pills
    In a traditional VCS, I can understand why you would not commit unresolved files because you could break the build. However, I don't understand why you shouldn't commit unresolved files in a DVCS (some of them will actually prevent you from committing the files). Instead, I think that your repository should be locked from pushing and pulling, but not committing. Being able to commit during the merging process has several advantages (as I see it): The actual merge changes are in history. If the merge was very large, you could make periodic commits. If you made a mistake, it would be much easier to roll back (without having to redo the entire merge). The files could remain flagged as unresolved until they were marked as resolved. This would prevent pushing/pulling. You could also potentially have a set of changesets act as the merge instead of just a single one. This would allow you to still use tools such as git rerere. So why is committing with unresolved files frowned upon/prevented? Is there any reason other than tradition?

  • Google Indexing Issue after htaccess changes

    - by Klement
    I have a site called www.FuneralCoverFinder.co.za. I have about 30 pages on the site and usually have 29 indexed. (Excluding 15 blog posts) They are new. I recently upgraded my entire site and made some redirection changes in my .htaccess file. I have made my url's more SEO friendly (Removing index.php/) and redirecting dead pages to working pages. I have tons of unique content all checked by grammarly and plagium to ensure I have no duplicate content. I have since resubmited my sitemap to Google and now have only one page indexed. It was within a couple of minutes. I usually see results almost immediately after submitting, now it's stuck on 1 page indexed. I assume I might have made errors in the .htaccess file as this was my first attempt. The site runs perfectly and all the url's redirect the way they should. I'm scared I have some or other loop, although the website runs fine. I still see many of my old indexed pages in the SERP's, I'm just worried that the issue with the new sitemap can cause my rankings some harm. My website is pretty SEO optimized onsite. I have about 1500 indexed backlinks and have been building them steadily over about half a year. I would really appreciate some clarity on this matter.

  • Git: Create a branch from unstagged/uncommited changes on master

    - by knoopx
    Context: I'm working on master adding a simple feature. After a few minutes I realize it was not so simple and it should have been better to work into a new branch. This always happens to me and I have no idea how to switch to another branch and take all these uncommited changes with me leaving the master branch clean. I supposed git stash && git stash branch new_branch would simply accomplish that but this is what I get: ~/test $ git status # On branch master nothing to commit (working directory clean) ~/test $ echo "hello!" > testing ~/test $ git status # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") ~/test $ git stash Saved working directory and index state WIP on master: 4402b8c testing HEAD is now at 4402b8c testing ~/test $ git status # On branch master nothing to commit (working directory clean) ~/test $ git stash branch new_branch Switched to a new branch 'new_branch' # On branch new_branch # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") Dropped refs/stash@{0} (db1b9a3391a82d86c9fdd26dab095ba9b820e35b) ~/test $ git s # On branch new_branch # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") ~/test $ git checkout master M testing Switched to branch 'master' ~/test $ git status # On branch master # Changed but not updated: # (use "git add <file>..." to update what will be committed) # (use "git checkout -- <file>..." to discard changes in working directory) # # modified: testing # no changes added to commit (use "git add" and/or "git commit -a") Do you know if there is any way of accomplishing this?

  • PeopleSoft Grants & the Federal Agency Letter of Credit Draw Changes

    - by Mark Rosenberg
    For decades, most, if not all, US Federal agencies that sponsor research allowed grant recipients to request and receive payments using pooled accounts, commonly known as pooled letter of credit (LOC) draws. This enabled organizations, such as universities and hospitals, fast and efficient access to reimbursement of the expenditures they incurred conducting research across a portfolio of grants. To support this business practice, the PeopleSoft Grants solution has delivered an LOC Draw report to provide the total request amount along with all of the supporting invoice details for reconciliation and audit purposes. Now, in an attempt to provide greater transparency, eliminate fraud, strengthen accountability for grant-related financial transactions, and simplify grant award closeout, many US Federal sponsors are transitioning from the “pooling” letter of credit draw method to requesting on a “grant-by-grant” basis. The National Science Foundation, the second largest issuer of Federal awards, already transitioned to detailed grant draws in 2013. And, in response to the U.S. Department of Health and Human Services (HHS) directive to HHS-supported Agencies, the largest Federal awards sponsor, the National Institutes of Health (NIH), will fully transition to the new HHS subaccount draw method. This will require NIH award recipients to request payments based on actual expenses incurred on an award-by-award basis. NIH is expected to fully transition to this new draw method by the end of Federal fiscal year 2015.  (The NIH had planned to fully transition to this new method by the end of fiscal 2014; however, the impact to institutions was deemed to be significant enough that a reprieve was recently granted.) In light of these new Federal draw requirements, we have recently released these new features to aid our customers on both PeopleSoft Grants releases 9.1 and 9.2:1. Federal Award Identification Number on the Proposal and Award Profile 2. Letter of credit fields on contract lines to support award basis draws and comply with Federal close out mandates3. Process to produce both pro forma and final LOC Draw Reports in BI Publisher report format4. Subacccount ID field on the LOC Summary and a new BI Publisher version of the LOC Summary report 5. Added Subaccount Field and contract info to be displayed on the LOC summary page6. Ability to generate by a variety of dimensions pro forma and invoiced draw listings 7. Queries for generation and manipulation of data to upload into sponsor payment request systems and perform payment matching8. Contracts LOC Close Out query to quickly review final balances prior to initiating final draws and preparing Federal Financial Reports prior to close The PeopleSoft Development team actively monitors this and other major Federal changes and continues working closely with the Grants Product Advisory Group of the Higher Education User Group to ensure a clear understanding of what our customers need in order to transition to new approaches for doing business with the Federal government. For more information regarding the enhancements to the PeopleSoft Grants solution, existing customers can login to My Oracle Support and review the Enhancements to Letter of Credit Process (Doc ID 1912692.1) associated with resolution ID 904830. This enhanced LOC functionality is available in both PeopleSoft FSCM 9.1 Bundle #31 and PeopleSoft FSCM 9.2 Update Image 8.

  • Windows disk change monitoring for malware analysis

    - by SuperDuck
    Not sure if this question belongs to here, because it has some relations with 'serverfault' (system backups) and 'stackoverflow' (software analysis). I'm looking for a solution to monitor disk changes on a Windows system and selectively revert them. It should be able to handle live files like registry parts, so may need to be an offline backup software. It shouldn't silently pass over files which the current admin user doesn't have permissions on (files with no permission entries or owned by the 'system' user) Registry change tracking would be a bonus but is not a requirement I use virtual machines for malware analysis, there is even no solution to list file changes in disk snapshot files (delta VMDK). I currently use Ashampoo for monitoring changes. Though it's the best one between similars, it's not a good software and hasn't really evolved in many 'platinum', 'deluxe' versions released in the last 10 years (it even used non-resizable windows until the latest version). The real problem is it misses some disk / registry changes. Perhaps it only compares modification dates and doesn't catch a change if the dates are preserved. So, I think the solution should compare files using hashes, or file sizes at least. There are numerous backup software out there and I'm sure one can handle this, offline or online.

  • how to combine changes tracked from several documents

    - by Jessica
    I tried to search the solution in internet, but found nothing, is there anyone who can help me? For my application, there is one document (Microsoft word), and this document is reviewed by several people in the "Track changes" mode, so the input to my application is the original document and the reviewed documents with changes (like insert/delete/comments). By this link , I know how to extract all the changes from the reviewed documents. what i want is to combine all the changes from all the reviewed documents into ONE document, and make all the changes "accepted", so the output of my application is one modified Microsoft document with all the changes (delete/insert/comment) accepted. My problem is that I don't know how to combine the changes from several documents into one single document. Anyone has an idea how to do this? Thank you very much in advance.

  • Restoring OutlineView Changes

    - by Geertjan
    Spent the last afternoons working with Ruben Hinojo, who I met recently at the Tinkerforge/NetBeans integration course in Germany. He's Spanish, lives in Scotland, and joined the course by flying from Edinburgh to Amsterdam and then driving from there to the course in Germany. Since then he spent some days in Amsterdam and we've been working a bit in a cafe in Amsterdam. He's working freelance on a freight management system on the NetBeans Platform and here's a pic of him and his application: I showed him a few things to improve the initial appearance of the application, such as removing the unneeded tab in the editor position and displaying data at startup so that the main window isn't empty initially. He, in turn, told me about something I didn't know about, where "freightViewer" below is an OutlineView: void writeProperties(java.util.Properties p) {     // better to version settings since initial version as advocated at     // http://wiki.apidesign.org/wiki/PropertyFiles     p.setProperty("version", "1.0");     freightViewer.writeSettings(p, "FreightViewer"); } void readProperties(java.util.Properties p) {     String version = p.getProperty("version");     freightViewer.readSettings(p, "FreightViewer"); } The "OutlineView.read/writeSettings" enables you to save/restore changes to an OutlineView, e.g., column width, column position, and which columns are displayed/hidden. In the user dir, within the .settings file of the TopComponent (in config/Windows2Local/Components), you'll then find content like this, where the "FreightViewer" argument above is now the prefix of the name of each property element: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE properties PUBLIC "-//org.ruben.viewer//RubenViewer//EN" "http://www.netbeans.org/dtds/properties-1_0.dtd"> <properties>     <property name="FreightViewerOutlineViewOutlineColumn-1-shortDescription" value="Type"/>     <property name="FreightViewerETableColumn-1-HeaderValue" value="Type"/>     <property name="FreightViewerColumnsNumber" value="3"/>     <property name="FreightViewerETableColumn-0-PreferredWidth" value="75"/>     <property name="FreightViewerETableColumn-2-HeaderValue" value="Description"/>     <property name="version" value="1.0"/>     <property name="FreightViewerETableColumn-2-SortRank" value="0"/>     <property name="FreightViewerETableColumn-2-Width" value="122"/>     <property name="FreightViewerETableColumn-0-ModelIndex" value="0"/>     <property name="FreightViewerETableColumn-1-Width" value="123"/>     <property name="FreightViewerHiddenColumnsNumber" value="0"/>     <property name="FreightViewerETableColumn-0-SortRank" value="0"/>     <property name="FreightViewerETableColumn-1-ModelIndex" value="1"/>     <property name="FreightViewerETableColumn-1-PreferredWidth" value="75"/>     <property name="FreightViewerETableColumn-0-Ascending" value="true"/>     <property name="FreightViewerETableColumn-2-ModelIndex" value="2"/>     <property name="FreightViewerETableColumn-1-Ascending" value="true"/>     <property name="FreightViewerETableColumn-2-PreferredWidth" value="75"/>     <property name="FreightViewerETableColumn-1-SortRank" value="0"/>     <property name="FreightViewerETableColumn-0-HeaderValue" value="Nodes"/>     <property name="FreightViewerETableColumn-2-Ascending" value="true"/>     <property name="FreightViewerETableColumn-0-Width" value="122"/>     <property name="FreightViewerOutlineViewOutlineColumn-2-shortDescription" value="Description"/> </properties> NB: However, note as described in this issue, i.e., since 7.2, hiding a column isn't persisted and in fact causes problems. I replaced the org-openide-explorer.jar with a previous one, from 7.1.1, and then the problem was solved. But now the enhancements in the OutlineView since 7.2 are no longer present, of course. So, looking forward to seeing this problem fixed.

  • LDAP replication breaking referrals

    - by MasterZ
    We have an issue that we believe is caused by ldap replication changing the port of the referal from 686 (secure) to 389 (unsecure). If we setup a new referral everything works, but then as soon as we change someone's password it changes on the master, and then the master replicates and the referral breaks. Any further attempts to modify someone's account give the error "PAM: Cannot connect to LDAP". We used snoop and monitored the firewall to see what was going on. The first password attempt (the one that works) goes over port 686 (as it is supposed to) but every subsequent attempt attempts to use port 389, and therefore fails. We only have 1 referral configured on the client, port 686

  • Edit write-protected files by breaking hard links

    - by Taymon
    A directory which I own and can write to contains hard links to files that I don't own and don't have write permission for. I want to open and edit these files in Emacs. When I save my changes, Emacs should rename the existing hard link by appending ~, then write my new version of the file as a new file owned by me. I was under the impression that Emacs could just do this (because of the way it does backups), but it's not working; when I save, it attempts to change the file's permissions in order to write to it (and fails because I don't own the file). How do I make this happen?

  • Cursor lag when mouse cursor changes?

    - by Mathias Lykkegaard Lorenzen
    Cursor lag issue Introduction I'm experiencing a newly arrived problem lately that frustrates me a lot. The computer I bought is a Clevo 150ERM. Two of my friends bought the same machine, and are experiencing the same issue. The computer came with Windows 7. There, I had no issues. Then, when we all switched to Windows 8, they had the mouse problem and I didn't. That is until after 4 or 5 months when I decided to install the RTM driver of my Intel graphics chip, and the latest Nvidia driver. I also installed the latest version of Skype that just released (Skype 6 and Skype for Metro). This basically leads me to conclude that the issue is not hardware-prone, and is not based on the operating system itself, rather the drivers or components that follow with it. Description of the issue The issue itself (lag with the mouse) happens whenever the cursor icon changes. For instance, if I keep hovering from and to a textfield (and the cursor changes into a caret and then back to a mouse), it stops for 200 milliseconds while it changes the icon. An example is if I follow the mouse in the pattern shown by the arrows below. When crossing the window border, the cursor changes into a "resize window" cursor for a short while, making the cursor lag. This doesn't sound like much, but it happens every time the cursor changes (even if it's to just move the mouse somewhere else, and accidentally make it cross a window border from where the resize cursor shows etc). What do you suggest I try?

  • Will final version of 12.04 use the power management changes found in kernel 3.3

    - by Luis Alvarado
    I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version. In this case, kernel 3.3 has seen some very good power management enhancements that are not all found in the kernel 3.2. My question then is: Will this updates in 3.3 be somehow pulled into the 3.2 kernel used for Ubuntu 12.04?

  • ASP.NET MVC Postbacks and HtmlHelper Controls ignoring Model Changes

    - by Rick Strahl
    So here's a binding behavior in ASP.NET MVC that I didn't really get until today: HtmlHelpers controls (like .TextBoxFor() etc.) don't bind to model values on Postback, but rather get their value directly out of the POST buffer from ModelState. Effectively it looks like you can't change the display value of a control via model value updates on a Postback operation. To demonstrate here's an example. I have a small section in a document where I display an editable email address: This is what the form displays on a GET operation and as expected I get the email value displayed in both the textbox and plain value display below, which reflects the value in the mode. I added a plain text value to demonstrate the model value compared to what's rendered in the textbox. The relevant markup is the email address which needs to be manipulated via the model in the Controller code. Here's the Razor markup: <div class="fieldcontainer"> <label> Email: &nbsp; <small>(username and <a href="http://gravatar.com">Gravatar</a> image)</small> </label> <div> @Html.TextBoxFor( mod=> mod.User.Email, new {type="email",@class="inputfield"}) @Model.User.Email </div> </div>   So, I have this form and the user can change their email address. On postback the Post controller code then asks the business layer whether the change is allowed. If it's not I want to reset the email address back to the old value which exists in the database and was previously store. The obvious thing to do would be to modify the model. Here's the Controller logic block that deals with that:// did user change email? if (!string.IsNullOrEmpty(oldEmail) && user.Email != oldEmail) { if (userBus.DoesEmailExist(user.Email)) { userBus.ValidationErrors.Add("New email address exists already. Please…"); user.Email = oldEmail; } else // allow email change but require verification by forcing a login user.IsVerified = false; }… model.user = user; return View(model); The logic is straight forward - if the new email address is not valid because it already exists I don't want to display the new email address the user entered, but rather the old one. To do this I change the value on the model which effectively does this:model.user.Email = oldEmail; return View(model); So when I press the Save button after entering in my new email address ([email protected]) here's what comes back in the rendered view: Notice that the textbox value and the raw displayed model value are different. The TextBox displays the POST value, the raw value displays the actual model value which are different. This means that MVC renders the textbox value from the POST data rather than from the view data when an Http POST is active. Now I don't know about you but this is not the behavior I expected - initially. This behavior effectively means that I cannot modify the contents of the textbox from the Controller code if using HtmlHelpers for binding. Updating the model for display purposes in a POST has in effect - no effect. (Apr. 25, 2012 - edited the post heavily based on comments and more experimentation) What should the behavior be? After getting quite a few comments on this post I quickly realized that the behavior I described above is actually the behavior you'd want in 99% of the binding scenarios. You do want to get the POST values back into your input controls at all times, so that the data displayed on a form for the user matches what they typed. So if an error occurs, the error doesn't mysteriously disappear getting replaced either with a default value or some value that you changed on the model on your own. Makes sense. Still it is a little non-obvious because the way you create the UI elements with MVC, it certainly looks like your are binding to the model value:@Html.TextBoxFor( mod=> mod.User.Email, new {type="email",@class="inputfield",required="required" }) and so unless one understands a little bit about how the model binder works this is easy to trip up. At least it was for me. Even though I'm telling the control which model value to bind to, that model value is only used initially on GET operations. After that ModelState/POST values provide the display value. Workarounds The default behavior should be fine for 99% of binding scenarios. But if you do need fix up values based on your model rather than the default POST values, there are a number of ways that you can work around this. Initially when I ran into this, I couldn't figure out how to set the value using code and so the simplest solution to me was simply to not use the MVC Html Helper for the specific control and explicitly bind the model via HTML markup and @Razor expression: <input type="text" name="User.Email" id="User_Email" value="@Model.User.Email" /> And this produces the right result. This is easy enough to create, but feels a little out of place when using the @Html helpers for everything else. As you can see by the difference in the name and id values, you also are forced to remember the naming conventions that MVC imposes in order for ModelBinding to work properly which is a pain to remember and set manually (name is the same as the property with . syntax, id replaces dots with underlines). Use the ModelState Some of my original confusion came because I didn't understand how the model binder works. The model binder basically maintains ModelState on a postback, which holds a value and binding errors for each of the Post back value submitted on the page that can be mapped to the model. In other words there's one ModelState entry for each bound property of the model. Each ModelState entry contains a value property that holds AttemptedValue and RawValue properties. The AttemptedValue is essentially the POST value retrieved from the form. The RawValue is the value that the model holds. When MVC binds controls like @Html.TextBoxFor() or @Html.TextBox(), it always binds values on a GET operation. On a POST operation however, it'll always used the AttemptedValue to display the control. MVC binds using the ModelState on a POST operation, not the model's value. So, if you want the behavior that I was expecting originally you can actually get it by clearing the ModelState in the controller code:ModelState.Clear(); This clears out all the captured ModelState values, and effectively binds to the model. Note this will produce very similar results - in fact if there are no binding errors you see exactly the same behavior as if binding from ModelState, because the model has been updated from the ModelState already and binding to the updated values most likely produces the same values you would get with POST back values. The big difference though is that any values that couldn't bind - like say putting a string into a numeric field - will now not display back the value the user typed, but the default field value or whatever you changed the model value to. This is the behavior I was actually expecting previously. But - clearing out all values might be a bit heavy handed. You might want to fix up one or two values in a model but rarely would you want the entire model to update from the model. So, you can also clear out individual values on an as needed basis:if (userBus.DoesEmailExist(user.Email)) { userBus.ValidationErrors.Add("New email address exists already. Please…"); user.Email = oldEmail; ModelState.Remove("User.Email"); } This allows you to remove a single value from the ModelState and effectively allows you to replace that value for display from the model. Why? While researching this I came across a post from Microsoft's Brad Wilson who describes the default binding behavior best in a forum post: The reason we use the posted value for editors rather than the model value is that the model may not be able to contain the value that the user typed. Imagine in your "int" editor the user had typed "dog". You want to display an error message which says "dog is not valid", and leave "dog" in the editor field. However, your model is an int: there's no way it can store "dog". So we keep the old value. If you don't want the old values in the editor, clear out the Model State. That's where the old value is stored and pulled from the HTML helpers. There you have it. It's not the most intuitive behavior, but in hindsight this behavior does make some sense even if at first glance it looks like you should be able to update values from the model. The solution of clearing ModelState works and is a reasonable one but you have to know about some of the innards of ModelState and how it actually works to figure that out.© Rick Strahl, West Wind Technologies, 2005-2012Posted in ASP.NET  MVC   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • How to apply programatical changes to the Terrain SplatPrototype

    - by Shivan Dragon
    I have a script to which I add a Terrain object (I drag and drop the terrain in the public Terrain field). The Terrain is already setup in Unity to have 2 PaintTextures: 1 is a Square (set up with a tile size so that it forms a checkered pattern) and the 2nd one is a grass image: Also the Target Strength of the first PaintTexture is lowered so that the checkered pattern also reveals some of the grass underneath. Now I want, at run time, to change the Tile Size of the first PaintTexture, i.e. have more or less checkers depending on various run time conditions. I've looked through Unity's documentation and I've seen you have the Terrain.terrainData.SplatPrototype array which allows you to change this. Also there's a RefreshPrototypes() method on the terrainData object and a Flush() method on the Terrain object. So I made a script like this: public class AStarTerrain : MonoBehaviour { public int aStarCellColumns, aStarCellRows; public GameObject aStarCellHighlightPrefab; public GameObject aStarPathMarkerPrefab; public GameObject utilityRobotPrefab; public Terrain aStarTerrain; void Start () { //I've also tried NOT drag and dropping the Terrain on the public field //and instead just using the commented line below, but I get the same results //aStarTerrain = this.GetComponents<Terrain>()[0]; Debug.Log ("Got terrain "+aStarTerrain.name); SplatPrototype[] splatPrototypes = aStarTerrain.terrainData.splatPrototypes; Debug.Log("Terrain has "+splatPrototypes.Length+" splat prototypes"); SplatPrototype aStarCellSplat = splatPrototypes[0]; Debug.Log("Re-tyling splat prototype "+aStarCellSplat.texture.name); aStarCellSplat.tileSize = new Vector2(2000,2000); Debug.Log("Tyling is now "+aStarCellSplat.tileSize.x+"/"+aStarCellSplat.tileSize.y); aStarTerrain.terrainData.RefreshPrototypes(); aStarTerrain.Flush(); } //... Problem is, nothing gets changed, the checker map is not re-tiled. The console outputs correctly tell me that I've got the Terrain object with the right name, that it has the right number of splat prototypes and that I'm modifying the tileSize on the SplatPrototype object corresponding to the right texture. It also tells me the value has changed. But nothing gets updated in the actual graphical view. So please, what am I missing?

  • Ubuntu Software Center does not allow changes to software sources

    The checkboxes that appear to be changeable under the Edit / Software Sources dialog box cannot be changed. I click on them and they just turn gray and stay at their current setting. Update: When I run software-center from a terminal window and try to change one of the checkbox settings, I get: Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/softwareproperties/gtk/SoftwarePropertiesGtk.py", line 649, in on_isv_source_toggled self.backend.ToggleSourceUse(str(source_entry)) File "/usr/lib/python2.7/dist-packages/dbus/proxies.py", line 143, in __call__ **keywords) File "/usr/lib/python2.7/dist-packages/dbus/connection.py", line 630, in call_blocking message, timeout) dbus.exceptions.DBusException: com.ubuntu.SoftwareProperties.PermissionDeniedByPolicy: com.ubuntu.softwareproperties.applychanges These things happen instead of it properly prompting me for a password (for root privs).

  • Amazon Product Advertising API SOAP Namespace Changes

    - by Rick Strahl
    About two months ago (twowards the end of February 2012 I think) Amazon decided to change the namespace of the Product Advertising API. The error that would come up was: <ItemSearchResponse > was not expected. If you've used the Amazon Product Advertising API you probably know that Amazon has made it a habit to break the services every few years or so and I guess last month was about the time for another one. Basically the service namespace of the document has been changed and responses from the service just failed outright even though the rest of the schema looks fine. Now I looked around for a while trying to find a recent update to the Product Advertising API - something semi-official looking but everything is dated around 2009. Really??? And it's not just .NET - the newest thing on the sample/APIs is dated early 2011 and a handful of 2010 samples. There are newer full APIs for the 'cloud' offerings, but the Product Advertising API apparently isn't part of that. After searching for quite a bit trying to trace this down myself and trying some of the newer samples (which also failed) I found an obscure forum post that describes the solution of getting past the namespace issue. FWIW, I've been using an old version of the Product Advertising API using the old Microsoft WSE3 services (pre-WCF), which provides some of the WS* security features required by the Amazon service. The fix for this code is to explicitly override the namespace declaration on each of the imported service method signatures. The old service namespace (at least on my build) was: http://webservices.amazon.com/AWSECommerceService/2009-03-31 and it should be changed to: http://webservices.amazon.com/AWSECommerceService/2011-08-01 Change it on the class header:[Microsoft.Web.Services3.Messaging.SoapService("http://webservices.amazon.com/AWSECommerceService/2011-08-01")] [System.Xml.Serialization.XmlIncludeAttribute(typeof(Property[]))] [System.Xml.Serialization.XmlIncludeAttribute(typeof(BrowseNode[]))] [System.Xml.Serialization.XmlIncludeAttribute(typeof(TransactionItem[]))] public partial class AWSECommerceService : Microsoft.Web.Services3.Messaging.SoapClient { and on all method signatures:[Microsoft.Web.Services3.Messaging.SoapMethodAttribute("http://soap.amazon.com/ItemSearch")] [return: System.Xml.Serialization.XmlElementAttribute("ItemSearchResponse", Namespace="http://webservices.amazon.com/AWSECommerceService/2011-08-01")] public ItemSearchResponse ItemSearch(ItemSearch ItemSearch1) { Microsoft.Web.Services3.SoapEnvelope results = base.SendRequestResponse("ItemSearch", ItemSearch1); return ((ItemSearchResponse)(results.GetBodyObject(typeof(ItemSearchResponse), this.SoapServiceAttribute.TargetNamespace))); } It's easy to do with a Search and Replace on the above strings. Amazon Services <rant> FWIW, I've not been impressed by Amazon's service offerings. While the services work well, their documentation and tool support is absolutely horrendous. I was recently working with a customer on an old AWS application and their old API had been completely removed with a new API that wasn't even a close match. One old API call resulted in requiring three different APIs to perform the same functionality. We had to re-write the entire piece from scratch essentially. The documentation was downright wrong, and incomplete and so scattered it was next to impossible to follow. The examples weren't examples at all - they're mockups of real service calls with fake data that didn't even provide everything that was required to make same service calls work. Additionally there appears to be just about no public support from Amazon, only peer support which is sparse at best - and getting a hold of somebody at Amazon, even for pay seems to be mythical task. It's a terrible business model they have going. I can't see why anybody would put themselves through this sort of customer and development experience. Sad really, but an experience we see more and more these days. Nobody puts in the time to document anything anymore, leaving it to devs to figure this stuff out over and over again… </rant>© Rick Strahl, West Wind Technologies, 2005-2012Posted in CSharp  Web Services   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

  • VNC client not working -- Not able to see the changes happening on the other side

    - by javanoob
    Here is the Problem: I have two computers connected in the same LAN. I am trying to access one computer from another using Remote Desktop Viewer, I am able to see the remote desktop. But when i click on any thing or perform any action, I dont see the result but the action is performed on the remote desktop..But it is not refreshed on the remote desktop screen.. For Ex: 1) Opened Remote Desktop viewer 2) Connected to the other computer which has yahoo home page opened 3) Clicked on the close button of the web page 4) Action is performed on the other computer (Yahoo page is closed). 5) On Remote Desktop screen i still see the Yahoo home page 6) Whatever action i perform on remote desktop screen i see the same screen(In this case yahoo home page) Bottom line: Whatever screen i see on the start up of Remote Desktop viewer that is not getting refreshed. So the thing is though i am able to perform actions on remote desktop, the screen is not refreshing.. How do i solve this? I hope i made my point clear.. NOTE: I am connecting to Ubuntu 9.04 machine from Ubuntu 10.04LTS.. I am really not sure if that makes any difference.

  • How to handle canonical url changes like Stack Overflow

    - by lulalala
    Stack Overflow sites all have pretty urls which include the question title. In the HTML it also have canonical url for that page. I just found out that when I change the question title, the url is changed immediately. The canonical url is also updated. Does it mean that as long as the page with the old canonical url redirects to the new canonical url, then search engines will update their records of the canonical url as well? Is there anything else that one can actively do to make the url change even more smoother?
