  • Adding existing entity to navigation property of a different entity

    - by Shay Friedman
    I'm using EF4 and I'm running into a problem when I try to do something that looks quite trivial to me. I have two entities, let's call them A and B. These entities have a many-to-many association between them with a navigation property on A that contains a list of related B entities. What I want to do is to add existing B entities to a new A entity. When I try to do that, I get an exception: AcceptChanges cannot continue because the object's key values conflict with another object in the ObjectStateManager. Make sure that the key values are unique before calling AcceptChanges. Has anyone run into such a problem?

  • UI Automation / Retrieve File Extension / C#

    - by AP
    Dear all, I am tasked with a project that requires me to retreieve a specific file from a folder where I can only get an X and Y on the screen. While in XP I managed to use the fact that windows explorer is in essence a list view, and used the WM_HITTEST message to obtain information about the file, in Windows 7, this is not the case. To solve this problem, I am using UI Automation, which is a great tool for such things, only problem is that in the case, the windows handle I am looking at belongs to the desktop, and the desktop might have several files with the same name but with different extensions (and windows is configured to "hide extensions of known file types") UI automation does not return the extension back to me. I have tried many things, but I cannot find any robust solution which would give me 100% success. Has anyone tried this? successfully? Would appreciate any pointers. Many thanks,

  • J2me Blackberry Numeric Input

    - by Paul
    Hello, I am developing a blackberry application using j2me and LWUIT (blackberry port). Everything works great except for the TextField in numeric mode. Basically when you have focus on the TextField you have to first go into "NUMERIC" mode (by pressing alt + aA) in order to input, which is not user friendly and a problem. The proposed solution is to use a TextArea instead that allows you to open a NATIVE type input box. The problem there is that the user needs to focus the field and then press the fire button which again is unfriendly. Does anyone know of any simple solutions? The few solutions i have in mind (but not sure how to do them): 1) Capture any keypress on the TextArea and go into NATIVE mode, instead of just the fire key. 2) Put the blackberry input mode into numeric using code for the whole form. Any advice will be appreciated. Many Thanks, Paul

  • LocalReport (WebForms) and Partial Trust, for PDF Generation

    - by Peet Brits
    My goal is to generate a PDF for display in a web page, either as aspx or with a generic handler. (This will link from a Silverlight page, but this is irrelevant to the problem.) The problem is that LocalReport (Microsoft.Reporting.WebForms; Microsoft.ReportViewer.WebForms.dll) requires full trust, and our hosting server does not allow full trust. I am aware that ReportViewer has a remote mode that will allow it to run with partial trust, but for that I need a report server url which should probably have full trust as well, which does not solve anything. So how do I generate PDFs from WebForms in a partially trusted environment?

  • Flash in firefox does not start unitl they show in page

    - by Leonardo
    I have this little problem. My client wanted two distinct swf on a web page: a viewer on top and a slideshow of images at bottom. Clicking a link on the slideshow make the viewer load a movie, by means of LocalConnection api. The slideshow has a default, so when the page is loaded a default movie start. This works nice on all browser. The only problem I have is on firefox. When screen resolution is too low, or the monitor is too small (netbook) the slideshow remain hidden until scrolling. Therefore at page loading it doesn't start and the main viewer don't get instructed on playing the default video. As soon as I scroll the page, and the slideshow swf display on page, it starts and everything works fine. Do you know if there are any solution to this ? I cannot change the design, I must have two distinct swf, they come from a library he has, and I am trying to reuse components. thanks Leonardo

  • SQL 2008 Database tuning advisor won't start

    - by Andrew Hancox
    For some reason I can't get DTA to connect to my development machine. It connects to a remote DB just fine but when I point it to my dev machine I get an error saying: Failed to initialize MSDB database for tuning (exit code: -1073741819). I'm pretty sure it's not a permissions issue since I've used profiler to capture what it's doing and all of the commands it's run so far look fine and are being run under my account which is associated with the sysadmin role, when I run them in sql management studio they go through fine. I'm pretty convinced that the problem is related to creating the objects in MSDB that are used by DTA but I tried creating these manually (I found scripts on the web) and it just seems to push the problem along the line slightly. I'm going out of my mind - have even tried reinstalling SQL but that's not fixed it. I'm using SQL 2008 with SP1 (10.0.2531) on windows server 2008 (patched up to date). SAVE ME!!!!!

  • How to get scrollTop of page afer browser scrolled such page?

    - by Marco Demaio
    I know how to get the scrollTop of a page, I use this simple JS function (code copied around): function GetScrolledTop() { //I never work in IE quirkmode, I always use DOCTYPE as 1st line, so I don't need to test for document.body.scrollTop return self['pageYOffset'] || document.documentElement.scrollTop; } This works and my problem is the following: I tried to add it in the page onload event <body onload="alert(GetScrolledTop());"> On page load I get ZERO (which make sense), but the problem is that I get ZERO even if I scroll the page and then reload it without touching the scrollbar. It seems like the browser does: loads page calls my GetScrolledTop() (so obviously shows ZERO) then scrolls the page to where it was before. Do you know how to get the scolledTop after the step 3? I mean how to get the scrolledTop AFTER the browser scrolled the page? (maybe without using a timer) Thanks!

  • How to find the longest contiguous subsequence whose reverse is also a subsequence

    - by iecut
    Suppose I have a sequence x1,x2,x3.....xn, and I want to find the longest contiguous subsequence xi,xi+1,xi+2......xi+k, whose reverse is also a subsequence of the given sequence. And if there are multiple such subsequences, then I also have to find the first. ex:- consider the sequences: abcdefgedcg here i=3 and k=2 aabcdddd here i=5, k=3 I tried looking at the original longest common subsequence problem, but that is used to compare the two sequences to find the longest common subsequence.... but here is only one sequence from which we have to find the subsequences. Please let me know what is the best way to approach this problem, to find the optimal solution.

  • Android app (with felix) crashes with LinearAlloc exceeded capacity

    - by user1106000
    I am running apache felix and an osgi app on android (3.2). This works pretty well so far, but I have rather large chunks of data to load into the application (osgi bundles). The problem with that is that when I load the biggest chunk of data I get LinearAlloc exceeded capacity The error seems to come from LinearAlloc.c \#define DEFAULT_MAX_LENGTH (4*1024*1024) if (nextOffset > pHdr->mapLength) { /* * We don't have to abort here. We could fall back on the system * malloc(), and have our "free" call figure out what to do. Only * works if the users of these functions actually free everything * they allocate. */ LOGE("LinearAlloc exceeded capacity, last=%d\n", (int) size); dvmAbort(); } afaik in 3.2/4.x it is even 8*1024*1024, but I still hit that limit. I'm looking to get better insight on what causes this problem and how I might possibly be able to fix it. Any help would be appreciated.

  • "svn: Delta source ended unexpectedly" and proxy server

    - by Vladimir Bezugliy
    I cannot checkout working copy if I use proxy server. SVN starting to checkout files but, checkout several files but then stops and shows following error: svn: Delta source ended unexpectedly I can checkout working copy if I work without proxy server. But I constantly have problems if I work via proxy. Is this problem with proxy server or with svn? UPDATED: I tried to access other svn repositories located on different servers via proxy and it seems to me that I have problem only with one svn server. Other svn servers are accessible via proxy server.

  • Custom validator not invoked when using Validation Application Block through configuration

    - by Chris
    I have set up a ruleset in my configuration file which has two validators, one of which is a built-in NotNullValidator, the other of which is a custom validator. The problem is that I see the NotNullValidator hit, but not my custom validator. The custom validator is being used to validate an Entity Framework entity object. I have used the debugger to confirm the NotNull is hit (I forced a failure condition so I saw it set an invalid result), but it never steps into the custom one. I am using MVC as the web app, so I defined the ruleset in a config file at that layer, but my custom validator is defined in another project. However, I wouldn't have thought that to be a problem because when I use the Enterprise Library Configuration tool inside Visual Studio 2008 it is able to set the type properly for the custom validator. As well, I believe the custom validator is fine as it builds ok, and the config tool can reference it properly. Does anybody have any ideas what the problem could be, or even what to do/try to debug further? Here is a stripped down version of my custom validator: [ConfigurationElementType(typeof(CustomValidatorData))] public sealed class UserAccountValidator : Validator { public UserAccountValidator(NameValueCollection attributes) : base(string.Empty, "User Account") { } protected override string DefaultMessageTemplate { get { throw new NotImplementedException(); } } protected override void DoValidate(object objectToValidate, object currentTarget, string key, ValidationResults results) { if (!currentTarget.GetType().Equals(typeof(UserAccount))) { throw new Exception(); } UserAccount userAccountToValidate = (UserAccount)currentTarget; // snipped code ... this.LogValidationResult(results, "The User Account is invalid", currentTarget, key); } } Here is the XML of my ruleset in Validation.config (the NotNull rule is only there to force a failure so I could see it getting hit, and it does): <validation> <type defaultRuleset="default" assemblyName="MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="MyProj.Entities.UserAccount"> <ruleset name="default"> <properties> <property name="HashedPassword"> <validator negated="true" messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="Microsoft.Practices.EnterpriseLibrary.Validation.Validators.NotNullValidator, Microsoft.Practices.EnterpriseLibrary.Validation, Version=4.1.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="Not Null Validator" /> </property> <property name="Property"> <validator messageTemplate="" messageTemplateResourceName="" messageTemplateResourceType="" tag="" type="MyProj.Entities.UserAccountValidator, MyProj.Entities, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" name="Custom Validator" /> </property> </properties> </ruleset> </type> </validation> And here is the stripped down version of the way I invoke the validation: var type = entity.GetType() var validator = ValidationFactory.CreateValidator(type, "default", new FileConfigurationSource("Validation.config")) var results = validator.Validate(entity) Any advice would be much appreciated! Thanks, Chris

  • Microsoft SQL 2005 - using the modulo operator

    - by cc0
    So I have a silly problem, I have not used much MSSQL before, or any SQL for that matter. I basically have a minor mathematical problem that I need solved, and I thought modulo would be good. I have a number of dates in the database, but I need them be rounded off to the closest [dynamic integer] (could be anything from 0 to 5000000) which will be input as a parameter each time this query is called. So I thought I'd use modulo to find the remainder, then subtract that remainder from the date. If there is a better way, or an integrated function, please let me know! What would be the syntax for that? I've tried a lot of things, but I keep getting error messages like integers/floats/decimals can't be used with the modulo operators. I tried casting to all kinds of numeric datatypes. Any help would be appreciated.

  • How to CompareTo two Object without known about their real type

    - by Kamil
    I have to implement a one linked list but it should put object in appropriate position. Everything was OK when I use it in conjunction with specific class, but when I tried make it universal and argument of method insert was Object some problem appeared. When I want to input Object in right position I should use CompareTo method, but there isn't method in Object class! The problem is how to compare two object elements without known about their real types. Maybe I should use generic class type? But what about CompareTo? Or maybe combine with Element class and place CompareTo there? I suppose it is feasible. :) public void insert(Object o) { Element el = new Element(o); // initializing and setting iterators while(!it.isDone() && ((it.current().getValue())).CompareTo(o)<0) // it.current() returns Element of List { //move interators } //... }

  • Adding a sortcomparefunction to Dynamic Data Grid in flex

    - by Tom
    Hi, I am trying to create a dynamic datagrid in Flex 3, I have a list of columns a list of objects which correspond to datapoints for those columns which I fetch from a url. While the grid works perfectly fine the problem is that sorting on the columns is done in lexical order. I am aware that this can be fixed by adding a sortcomparefunction to a column, which is not easy for this case. I have tried doing var dgc:DataGridColumn = new DataGridColumn(dtf); f1[dtf] = function(obj1:Object, obj2:Object):int { return Comparators.sortNumeric(obj1[dtf],obj2[dtf]); }; dgc.sortCompareFunction = f1[dtf];` But the problem is that the function object that I am creating here is being overwritten in every iteration (as I am adding columns) and eventually all the columns will have sorting done only on the last column added. Suggestions please.

  • Silverlight running in IE kiosk mode

    - by JimmySavile
    Hi, We are having a weird problem where by we are running a silveright application in IE8 kiosk mode, the shortcut is added to windows startup. The silverlight app runs on localhost. It all works fine until you reboot, IE displays "navigation to the webpage was canceled" when it loads. Yet the shortcut works fine, if you close IE and manually go into the startup folder and run the shortcut, or run the same shortcut from the desktop. I assume there is some sort of timing issue but have no idea what. Tried using 127.0.0.1 instead of localhost incase DNS hadn't been properly initialised at that point or something. Maybe an IIS initialisation problem? Anyone have any ideas? Thanks for your time

  • Websphere MQ using JMS, closed connections stuck on the MQ

    - by Ahmad
    I have a simple JMS application deployed on OC4J under AIX server, in my application I'm listening to some queues and sending to other queues on a Websphere MQ deployed under AS400 server. The problem is that my connections to these queues are terminated/closed when it stays idle for some time with the error MQJMS1016 (this is not the problem), and when that happens I attempt to recover the connection and it works, however, the old connection is stuck at the MQ and would not terminate until it is terminated manually. The recovery code goes as follows: public void recover() { cleanup(); init(); } public void cleanup(){ if (session != null) { try { session .close(); } catch (JMSException e) { } } if (connection != null) { try { connection.close(); } catch (JMSException e) { } } } public void init(){ // typical initialization of the connection, session and queue... }

  • Why can't WordPress create directories when uploading themes?

    - by Arman
    I can't workout how to solve this problem so wordpress would let me upload themes. I have a fresh copy of Fedora 17 installed on my dev machine. I then installed mysql using: yum install mysql mysql-server. Next I installed WordPress which also installs apache and php: yum install wordpress I can go to http://localhost/wordpress and see WordPress working. But when I try tried to install my theme it asked for ftp credentials. I then updated the wp-config.php file and set the FS_METHOD constant to direct. Now it doesn't ask for ftp credentials but it gives me this error: Could not create directory. /usr/share/wordpress/wp-content/themes/my-theme-name/ httpd service is running under 'apache' user and 'apache' group. The /usr/share/wordpress/ directory is recursively own by 'apache' user and 'apache' group too. I've even set the permissions to 777 (also recursively) and even then I keep getting the same error as above. How can I solve this problem?

  • calculating the potential effect of inaccurate triangle vertex positions on the triangle edge lenght

    - by stingrey
    i'm not sure how to solve the following problem: i have a triangle with each of the three known vertex positions A,B,C being inaccurate, meaning they can each deviate up to certain known radii rA, rB, rC into arbitrary directions. given such a triangle, i want to calculate how much the difference of two specific edge lengths (for instance the difference between lengths of edge a and edge b) of the triangle may change in the worst case. is there any elegant mathematical solution to this problem? the naive way i thought of is calculating all 360^3 angle combinations and measuring the edge differences for each case, which is a rather high overhead.

  • Asynchronous subprocess on Windows

    - by Stigma
    First of all, the overall problem I am solving is a bit more complicated than I am showing here, so please do not tell me 'use threads with blocking' as it would not solve my actual situation without a fair, FAIR bit of rewriting and refactoring. I have several applications which are not mine to modify, which take data from stdin and poop it out on stdout after doing their magic. My task is to chain several of these programs. Problem is, sometimes they choke, and as such I need to track their progress which is outputted on STDERR. pA = subprocess.Popen(CommandA, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE) # ... some more processes make up the chain, but that is irrelevant to the problem pB = subprocess.Popen(CommandB, shell=False, stdout=subprocess.PIPE, stderr=subprocess.PIPE, stdin=pA.stdout ) Now, reading directly through pA.stdout.readline() and pB.stdout.readline(), or the plain read() functions, is a blocking matter. Since different applications output in different paces and different formats, blocking is not an option. (And as I wrote above, threading is not an option unless at a last, last resort.) pA.communicate() is deadlock safe, but since I need the information live, that is not an option either. Thus google brought me to this asynchronous subprocess snippet on ActiveState. All good at first, until I implement it. Comparing the cmd.exe output of pA.exe | pB.exe, ignoring the fact both output to the same window making for a mess, I see very instantaneous updates. However, I implement the same thing using the above snippet and the read_some() function declared there, and it takes over 10 seconds to notify updates of a single pipe. But when it does, it has updates leading all the way upto 40% progress, for example. Thus I do some more research, and see numerous subjects concerning PeekNamedPipe, anonymous handles, and returning 0 bytes available even though there is information available in the pipe. As the subject has proven quite a bit beyond my expertise to fix or code around, I come to Stack Overflow to look for guidance. :) My platform is W7 64-bit with Python 2.6, the applications are 32-bit in case it matters, and compatibility with Unix is not a concern. I can even deal with a full ctypes or pywin32 solution that subverts subprocess entirely if it is the only solution, as long as I can read from every stderr pipe asynchronously with immediate performance and no deadlocks. :)

  • Execute a function when a <link> element has finished loading

    - by nornagon
    I'm using jQuery Masonry to lay out my page, but I'm using a custom @font-face font. The problem being that Masonry doesn't know the metrics of the font until it's loaded. The Masonry docs suggest that you use $(window).load() instead of $(document).ready() to call the layout functions, but I don't want to have to wait until all the images etc. load. I can specify the dimensions of the images exactly, so Masonry doesn't need to wait until they're loaded. It's just the text that's the problem. How can I get jQuery to call a callback when the <link> element that links in the font finishes loading?

  • Preserving text formatting for dynamic website

    - by Mohit
    Hello Folks, I am facing a problem while creating a dynamic website. I am building it for some pharma company, which have many products. The problem is, every product have different sections of description, and have to be formatted differently. I wanted to store all the product descriptions in the database, but at the same time preserve the formatting of each description. I also plan to provide an admin interface, where they could edit the product information themselves. I could use Joomla or any other CMS for that purpose, but i wanted to know if i want to build such a system of my own, where i could format the text in an editor and them save that thing into database and when i retrieve it, i get the same formatting. How could i do this? Also i wanted to do this in PHP. Thanks -- Mohit
