  • MVC3 Razor DropDownListFor Enums

    - by jordan.baucke
    Trying to get my project updated to MVC3, something I just can't find: I have a simple datatype of ENUMS: public enum States() { AL,AK,AZ,...WY } Which I want to use as a DropDown/SelectList in my view of a model that contains this datatype: public class FormModel() { public States State {get; set;} } Pretty straight forward: when I go to use the auto-generate view for this partial class, it ignores this type. I need a simple select list that sets the value of the enum as the selected item when I hit submit and process via my AJAX - JSON POST Method. And than the view (???!): <div class="editor-field"> @Html.DropDownListFor(model => model.State, model => model.States) </div> thanks in advance for the advice!

  • strerror_r returns trash when I manually set errno during testing

    - by Robert S. Barnes
    During testing I have a mock object which sets errno = ETIMEDOUT; The object I'm testing sees the error and calls strerror_r to get back an error string: if (ret) { if (ret == EAI_SYSTEM) { char err[128]; strerror_r(errno, err, 128); err_string.assign(err); } else { err_string.assign(gai_strerror(ret)); } return ret; } I don't understand why strerror_r is returning trash. I even tried calling strerror_r(ETIMEDOUT, err, 128) directly and still got trash. I must be missing something. It seems I'm getting the gnu version of the function not the posix one, but that shouldn't make any difference in this case.

  • One click login to my google apps solution how can I do it?

    - by Ali
    Hi guys I'm developing a google apps solution and I'm building on the tutorial application give by google at http://code.google.com/googleapps/marketplace/tutorial_php.html - the thing is that the example given sets up the application such that the user has to enter in manually the email address or username and then it takes the user through an authentication process whereby it asks the user if they wish to allow the application to be given access to the services mentioned in the manifest.xml file. Isn't there a better way to do this I mean like I want that when the user upon logging into his google apps account just has to click in the application link installed and straight on should be able to enter the application. Can't the process of authentication and all be transparent in the backdrop. I need help on this asap. Thanks a bunch!

  • Subversion and project management web based super tool. Like Team Foundation Server but not TFS.

    - by Rob Stevenson-Leggett
    Hi, We're currently looking at an IT upgrade and I'm after recommendations for a tool which can do some or all of the following. SVN management (authz, web viewer, commit log, diff) Create template projects (1 click e.g. create me a microsite with this name in svn and give these people access) Reporting on code churn, time spent on tasks on a per project basis User story management Basically like Team Foundation Server but that integrates with SVN properly (reason for this - we have a wide range of skill sets and not everyone can use a TFS client). Is there a combination of Trac plugins + something that can create trac instances (a la Dreamhost's admin panel) that can acheive this. On a side note, does anyone have any experience of version controlling designery type files - e.g. PSDs, Illustrator files. Any advice at all appreciated. Cheers, Rob

  • ExtJS TabPanel content does not shrink in IE6

    - by joshowen
    I'm using ExtJS 3.2 and have content inside of a tab panel, and the tab panel inside of a container in a Viewport. The actual TabPanel resizes correctly on the viewport size changes, but the content inside a panel in the TabPanel seems to be a fixed width and will not shrink when the window is resized.The strange thing is it grows if I increase the window size. How can I get the content inside a Tabpanel to shrink on window resizing. Sorry for this being confusing, my structure is this: Viewport (rendered to body, and sets defaults {monitorResize:true}) - Text Label - TabPanel - Tab - Container (Border Layout) - Panel 1 (Center) - Panel 2 (East) - Panel 3 (South) Thanks in advance!

  • Blackberry pixel-specific animated focus scrolling

    - by Diego Tori
    Suppose I have a VFM full of both focusable and non-focusable fields. Since most of them are spread out far apart, the movement from one focused field to another is jerky at best, even with NullFields in between. In other words, it just sets the current y position to the next focused field without smoothly scrolling the screen. What I want to achieve is to be able to scroll at a fixed rate between fields, so it it doesn't just focus from one to another that instantaneously. After reading up on how to do this, it is a matter of overriding moveFocus and setting it via a TimerTask from an accessor method to set moveFocus, as per this link. However, I haven't seen a practical implementation of how to do this, complete with the routines that are called in the TimerTask's thread. Is there any way to achieve this type of behavior?

  • How should I handle incomplete packet buffers?

    - by Benjamin Manns
    I am writing a client for a server that typically sends data as strings in 500 or less bytes. However, the data will occasionally exceed that, and a single set of data could contain 200,000 bytes, for all the client knows (on initialization or significant events). However, I would like to not have to have each client running with a 50 MB socket buffer (if it's even possible). Each set of data is delimited by a null \0 character. What kind of structure should I look at for storing partially sent data sets? For example, the server may send ABCDEFGHIJKLMNOPQRSTUV\0WXYZ\0123!\0. I would want to process ABCDEFGHIJKLMNOPQRSTUV, WXYZ, and 123! independently. Also, the server could send ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890LOL123HAHATHISISREALLYLONG without the terminating character. I would want that data set stored somewhere for later appending and processing. Also, I'm using asynchronous socket methods (BeginSend, EndSend, BeginReceive, EndReceive) if that matters.

  • python and paramiko: how to check if end of ssh tunnel is still alive and reestablish if not?

    - by Christian
    Hello all, I'm trying to achieve the following: I have two hosts A and B. A establishes a remote port forwarding tunnel on B, i.e. B is the one a port is forwarded on to some where else and A is the one that sets up the tunnel. I tried the script rforward.py that ships with paramiko and it works very well so far. (I'm running rforward.py on A, which connects to B and forwards a port of B to somewhere else) However, when B is shutting down, A doesn't seem to recognize it. I'd rather like A to recognize that B is down and to try to reestablish the connection periodically in case B comes up again. Is there a way to do this? Thanks.

  • JLabel withing another JLabel

    - by out_sider
    I want to do a very simple thing with java swing and I'm not being able to. I added a jLabel as it is the only object using java swing that can hold an image (using the icon property)...at least I wasn't able to set an image using other objects. Now I want to add another jlabel in top of the first one with another image so it can be "clicked" independently from the "background" label. But whenever I try to add it using the graphical editor or by doing jLabel1.add(jLabel2) it doesn't work...it simply sets next to the label1 but not on top of it. This is in order to do a java application like the Tic Tac Toe game...so I can have the background which are squares (first label) and the others the "X" and "O". board This might be the board and I want to put labels on each square so they can be the pieces.

  • Lose changed data in session

    - by user150528
    Our asp.net 2.0 application has a very long process (synchronized) before sending response back to client. I observed that a second request, exactly same the initial one, was sent after client IE8 waited response for a long period of time while our application was still processing the first request. I use page session with predefined key to store a flag when the initial request arrives and then starts long process while client IE waits for the response, so if second request comes in, our application checks the session value. After our application sets the session flag and starts processing, I use Fiddler “Abort Session” to abort the initial request, right away the second request (same as the first one) is sent automatically, but session value set earlier seems no longer exist. Any thoughts?

  • weird characters in HTML email

    - by sims
    Hi stackers! I'm reading email from a maildir and some emails have weird sets of characters in them: =3D =09 I think =3D is = and =09 is a space. There are some others, but I'm not sure: =E2 =80 =93 Does anyone know what these are and what encoding issues I'm dealing with here? BTW, I tried fetching these email via POP3 and it's the same thing. The reason I'm posting this on SO is not because I'm using a regular mail client to read the data. I'm reading via PHP out of maildir files. Perhaps a regular email client would detect what encoding this is and deal with it. Thanks!

  • How do I open a web browser from a .NET Program? Process.Start() isn't working?

    - by Scott Whitlock
    I have a URL and I want to launch it in the default browser. I've tried two methods: Process.Start("http://stackoverflow.com"); ... and the one detailed in this other question using ShellExecute. In both cases I get the error: Windows cannot find 'http://stackoverflow.com'. Make sure you typed the name correctly, and then try again. It shouldn't be trying to open it as a file though... from what I understand, it should recognize it as a URL and open it in the default browser. What am I missing? By the way: OS = Vista, and .NET = 3.5 EDIT: According to this MS KB article, since Process.Start sets the UseShellExecute by default, it should launch the default browser.

  • Django: Admin with multiple sites & languages

    - by lazerscience
    Hi everybody! I'm supposed to build some Django apps, that allow you to administer multiple sites through one backend. The contrib.sites framework is quite perfect for my purposes. I can run multiple instances of manage.py with different settings for each site; but how should django's admin deal with different settings for different sites, eg. if they have different sets of languages, a different (default) language? So there are some problem s to face if you have to work on objects coming from different sites in one admin... I think settings.ADMIN_FOR is supposed to be quite helpful for cases like this, but theres hardly any documentation about it and I think it's not really used in the actual Django version (?). So any ideas/solutions are welcome and much appreciated! Thanks a lot...

  • whats the diference between train, validation and test set, in neural networks?

    - by Daniel
    Im using this library http://pastebin.com/raw.php?i=aMtVv4RZ to implement a learning agent. I have generated the train cases, but i dont know for sure what are the validation and test sets, the teacher says: 70% should be train cases, 10% will be test cases and the rest 20% should be validation cases. Thanks. edit i have this code, for training.. but i have no ideia when to stop training.. def train(self, train, validation, N=0.3, M=0.1): # N: learning rate # M: momentum factor accuracy = list() while(True): error = 0.0 for p in train: input, target = p self.update(input) error = error + self.backPropagate(target, N, M) print "validation" total = 0 for p in validation: input, target = p output = self.update(input) total += sum([abs(target - output) for target, output in zip(target, output)]) #calculates sum of absolute diference between target and output accuracy.append(total) print min(accuracy) print sum(accuracy[-5:])/5 #if i % 100 == 0: print 'error %-14f' % error if ? < ?: break

  • Why is Read-Modify-Write necessary for registers on embedded systems?

    - by Adam Shiemke
    I was reading http://embeddedgurus.com/embedded-bridge/2010/03/different-bit-types-in-different-registers/, which said: With read/write bits, firmware sets and clears bits when needed. It typically first reads the register, modifies the desired bit, then writes the modified value back out and I have run into that consrtuct while maintaining some production code coded by old salt embedded guys here. I don't understand why this is necessary. When I want to set/clear a bit, I always just or/nand with a bitmask. To my mind, this solves any threadsafe problems, since I assume setting (either by assignment or oring with a mask) a register only takes one cycle. On the other hand, if you first read the register, then modify, then write, an interrupt happening between the read and write may result in writing an old value to the register. So why read-modify-write? Is it still necessary?

  • Visual Studio Pre build events and batch set

    - by helloworld922
    Hi, I'm trying to create call a batch file which sets a bunch of environment variables prior to building. The batch file looks something like this (it's automatically generated before-hand to detect ATI Stream SDK or NVidia CUDA toolkit): set OCL_LIBS_X86="%ATISTREAMSDKROOT%libs\x86" set OCL_LIBS_X64="%ATISTREAMSDKROOT%libs\x86_64" set OCL_INCLUDE="%ATISTREAMSDKROOT%include" However, the rest of the build doesn't seem to have access to these variables, so when I try to reference $(OCL_INCLUDE) in the C/C++GeneralAdditional include directories, it will first give me warning that environment variable $(OCL_INCLUDE) was not found, and when I try to include CL/cl.hpp the compile will fail with: fatal error C1083: Cannot open include file: 'CL/cl.hpp': No such file or directory I know that I could put these variables into the registry if I wanted to access them from the visual studio GUI, but I would really prefer not to do this. Is there a way to to get these environment variables to stick after the pre-build events? I can't reference $(ATISTREAMSDKROOT) directly because the project must be able to build for both ATI Stream and NVidia Cuda.

  • How do I set up the Clojure classpath in Emacs after installing with ELPA?

    - by derefed
    I'm trying to add paths to my classpath in the Clojure REPL that I've set up in Emacs using ELPA. Apparently, this isn't the $CLASSPATH environment variable, but rather the swank-clojure-classpath variable that Swank sets up. Because I used ELPA to install Swank, Clojure, etc., there are a ton of .el files that take care of everything instead of my .emacs file. Unfortunately, I can't figure out how to change the classpath now. I've tried using (setq 'swank-clojure-extra-classpaths (list ...)) both before and after the ELPA stuff in my .emacs, and I've tried adding paths directly to swank-clojure-classpath in .emacs, .emacs.d/init.el, and .emacs.d/user/user.el, but nothing works. What I'm ultimately trying to do is to add both the current directory "." and the directory in which I keep my Clojure programs. I'm assuming swank-clojure-classpath is the thing I need to set here. Thanks for your help.

  • How does NSValue do its magic?

    - by Paperflyer
    I have an MVC application. The model has a property that is a struct NSSize. It is writable like this: - (void)setSize:(NSSize)aSize; The view sets this NSSize using key-value-coding. However, you can not key-value-code a struct, so I wrapped it in an NSValue-object like this: [theView setValue:[NSValue valueWithSize:mySize] forKey:@"theModel.size"]; To my understanding, this should not work since the accessor expects a struct and not an NSValue. But it works perfectly. Magically. How is this possible?

  • How do I customize what a third party MSM does?

    - by sqlrob
    I'm trying to convert a project in Visual Studio 2008 from static linking of the CRT to dynamic linking. This was easy enough, and I added the CRT MSM and policy MSM to my Wix file with no problems. I am not that happy with the MSI that is output though, it is much larger than what I expected. Looking at the MSI with Orca shows three copies of the CRT DLLs that I need. From looking at the conditions, one of the sets is used for pre-XP installs. Since the system requirements are XP and later, how do I remove this component without touching the original MSM? This needs to be done in an automated build, so Orca isn't a possible solution. Plus, when I tried it with Orca, the filesize remained the same after deleting the File and Component rows. And somewhat related, how do I set the permanent attribute in the components that remain?

  • (My)SQL performance: updating one field vs many unneccesary fields

    - by changokun
    i'm processing a form that has a lot of fields for a user who is editing an existing record. the user may have only changed one field, and i would typically do an update query that sets the values of all the fields, even though most of them don't change. i could do some sort of tracking to see which fields have actually changed, and only update the few that did. is there a performance difference between updating all fields in a record vs only the one that changed? are there other reasons to go with either method? the shotgun method is pretty easy...

  • Inherit static properties in subclass without redeclaration?

    - by David
    Hi, I'm having the same problem as this guy with the application I'm writing right now. The problem is that static properties are not being inherited in subclasses, and so if I use the static:: keyword in my main class, it sets the variable in my main class as well. It works if I redeclare the static variables in my subclass, but I expect to have a large number of static properties and subclasses and wish to avoid code duplication. The top-rated response on the page I linked has a link to a few "workarounds", but it seems to have 404'd. Can anyone lend me some help or perhaps point me in the direction of said workarounds?

  • Custom roles in ASP.NET

    - by MainMa
    Hi, I am working on an ASP.NET website which uses forms authentication with a custom authentication mechanism (which sets e.Authenticated programmatically on protected void Login_Authenticate(object sender, AuthenticateEventArgs e)). I have an ASP.NET sitemap. Some elements must be displayed only to logged in users. Others must be displayed only to one, unique user (ie. administrator, identified by a user name which will never change). What I want to avoid: Set a custom role provider: too much code to write for a such basic thing, Transform the existing code, for example by removing sitemap and replacing it by a code-behind solution. What I want to do: A pure code-behind solution which will let me assign roles on authenticate event. Is it possible? How? If not, is there an easy-to-do workaround?

  • SPARQL UNION - Result set incomplete

    - by jplevac
    I have two queries: query 1: SELECT DISTINCT ?o COUNT(?o) WHERE { ?s1 ?somep1 <predicate_one-uri>. ?s1 ?p ?o} query 2: SELECT DISTINCT ?o COUNT(?o) WHERE {?s2 ?somep2 <predicate_two-uri>.?s2 ?p ?o.} Each query gives me a different result set (as expected). I need to make a union of these two sets, from what I understand the query below should give me the set I want: SELECT DISTINCT ?o COUNT(?o) WHERE { { ?s1 ?somep1 <predicate_one-uri>.?s1 ?p1 ?o} UNION {?s2 ?somep2 <predicate_two-uri>.?s2 ?p2 ?o.} } The problem is that some results from query 1 are not in the union set and vice-versa for query 2. The union is not working properly as it does not incorporate all results of query 1 and query 2. Please advise on the proper structure of the sparql query for achieving the desired result set. Thanks in advance! JP Levac

  • How do I return an empty result set from a procedure using T-SQL?

    - by Kivin
    I'm interested in returning an empty result set from SQL Server stored procedures in certain events. The intended behaviour is that a L2SQL DataContext.SPName().SingleOrDefault() will result in CLR null value. I'm presently using the following solution, but I'm unsure whether it would be considered bad practice, a performance hazard (I could not find one by reading the execution plan), or if there is simply a better way: SELECT * FROM [dbo].[TableName] WHERE 0 = 1; The execution plan is a constant scan with a trivial cost associated with it. The reason I am asking this instead of simply not running any SELECTs is because I'm concerned previous SELECT @scalar or SELECT INTO statements could cause unintended result sets to be served back to L2SQL. Am I worrying over nothing?

  • Using set in Python inside a loop

    - by user210481
    I have the following list in Python: [[1, 2], [3, 4], [4, 6], [2, 7], [3, 9]] I want to group them into [[1,2,7],[3,4,6,7]] My code to do this looks like this: l=[[1, 2], [3, 4], [4, 6], [2, 7], [3, 9]] lf=[] for li in l: for lfi in lf: if lfi.intersection(set(li)): lfi=lfi.union(set(li)) break else: lf.append(set(li)) lf is my final list. I do a loop over l and lf and when I find an intersection between an element from l and another from lf, I would like to merge them (union) But I can't figure out why this is not working. The first to elements of the list l are being inserted with the append command, but the union is not working. My final list lf looks like [set([1, 2]), set([3, 4])] It seems to be something pretty basic, but I'm not familiar with sets. I appreciate any help Thanks
