  • Unable to write to a text file

    - by chrissygormley
    Hello, I am running some tests and need to write to a file. When I run the test's the open = (file, 'r+') does not write to the file. The test script is below: class GetDetailsIP(TestGet): def runTest(self): self.category = ['PTZ'] try: # This run's and return's a value result = self.client.service.Get(self.category) mylogfile = open("test.txt", "r+") print >>mylogfile, result result = ("".join(mylogfile.readlines()[2])) result = str(result.split(':')[1].lstrip("//").split("/")[0]) mylogfile.close() except suds.WebFault, e: assert False except Exception, e: pass finally: if 'result' in locals(): self.assertEquals(result, self.camera_ip) else: assert False When this test run's, no value has been entered into the text file and a value is returned in the variable result. I havw also tried mylogfile.write(result). If the file does not exist is claim's the file does not exist and doesn't create one. Could this be a permission problem where python is not allowed to create a file? I have made sure that all other read's to this file are closed so I the file should not be locked. Can anyone offer any suggestion why this is happening? Thanks

  • Loading GWT Messages from a Database

    - by Lars Tackmann
    In GWT one typically loads i18n strings using a interface like this: public interface StatusMessage extends Messages { String error(String username); : } which then loads the actual strings from a StatusMessage.property file: error=User: {0} does not have access to resource This is a great solution, however my client is unbendable in his demand for putting the i18n strings in a database so they can be changed at runtime (though its not a requirement that they be changed realtime). One solution is to create a async service which takes a message ID and user locale and returns a string. I have implemented this and find it terribly ugly (and it introduces a huge amount of extra communication with the server, plus it makes property placeholder replacement rather complicated). So my question is this, can I in some nice way implement a custom message provider that loads the messages from the backend in one big swoop (for the current user session). If it can also hook into the default GWT message mechanism, then I would be completely happy (i.e. so I can create a interface like above and keep using the the nice {0}, {1}... property replacement format). Other suggestions for clean database driven messages in GWT are also welcome.

  • Limiting object allocation over multiple threads

    - by John
    I have an application which retrieves and caches the results of a clients query. The client then requests different chunks of data and the application sends the relevant results and removes them from the cache. A new requirement for this application is that there needs to be a run-time configurable maximum number of results which may be cached. I've taken the naive approach and implemented this by using a counter under a lock which is incremented every time a result is cached and decremented whenever a result is removed from the cache. Unfortunately, this has drastically reduced the applications performance when processing a large number of concurrent requests. I have tried both a critical section lock and spin-lock; the performance improves a bit with a spin-lock, but is still unacceptably slow. Is there a better way to solve this problem which may improve performance? Right now I have a thread pool that services requests and each request is tied to a Request object which stores that cached results for that particular request. Here is a simplified pseudo code version of my current implementation: void ResultCallback( Result result, Request *request ) { lock totalResultsCached lock cachedLimit if( totalResultsCached + 1 > cachedLimit ) { unlock cachedLimit unlock totalResultsCached //cancel the request return; } ++totalResultsCached; unlock cachedLimit unlock totalResultsCached request.add(result) } void SendResults( int resultsToSend, Request *request ) { while ( resultsToSend > 0 ) { send(request.remove()) lock totalResultsCached --totalResultsCached unlock totalResultsCached --resultsToSend; } }

  • How best to implement support for multiple devices in a web application.

    - by Kabeer
    Hello. My client would like a business application to support 'every possible device'. The application in question is essentially a web application and 'every possible device', I believe encompasses mobile phones, netbooks, ipad, other browser supporting devices, etc. The application is somewhat complex w.r.t. the data it captures and other functions it performs (reporting). If I continue to honor increasing complexity in the application, I guess there are more chances of it not working on other devices. I'd like to know how web applications support multiple devices conventionally? Are there multiple versions of presentation layer (like many times I find m.website.com dedicated for mobile devices)? Further, if my application is to take advantage of Java Script, RIA (Flash, SilverLight) then what are the consequences and workarounds? Mine is a .Net based application and the stack also contains Ext JS Java Script library. While I would like to use it for sure, considering that I would be doing a lot of work in Java Script rather than HTML, this could be a problem. The answer to the above could be descriptive. If there is something already prescribed out there, please share the link(s). Thanks.

  • ASP.Net - Help with datagrid/checkboxes/double submit

    - by Gareth D
    We have a simple datagrid. Each row has a checkbox. The checkbox is set to autopostback, and the code-behind has an event handler for the checkbox check-changed event. This all works as expected, nothing complicated. However, we want to disable the checkboxes as soon as one is checked to prevent a double submit i.e. check box checked, all checkboxes are disabled via client side javascript, form submitted. To achieve this I we are injecting some code into the onclick event as follows (note that the alert is just for testing!): Protected Sub DgAccounts_ItemCreated(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles DgAccounts.ItemCreated If e.Item.ItemType = ListItemType.Item Or e.Item.ItemType = ListItemType.AlternatingItem Then Dim chk As CheckBox = CType(e.Item.FindControl("chkItemChecked"), CheckBox) chk.Attributes.Add("onclick", "alert('fired ...');DisableAllDataGridCheckBoxes();") End If End Sub When inspecting the source of the rendered page we get the following: <input id="DgAccounts__ctl2_chkItemChecked" type="checkbox" name="DgAccounts:_ctl2:chkItemChecked" onclick="alert('fired ...');DisableAllDataGridCheckBoxes();setTimeout('__doPostBack(\'DgAccounts$_ctl2$chkItemChecked\',\'\')', 0)" language="javascript" /> It all appears in order, however the server side event does not fire – I believe this is due to the checkbox being disabled, as if we just leave the alert in and remove the call to disable the checkbox it all works fine. Can I force the check-changed event to fire even though the check box is disabled?

  • Manipulating/changing adressbar link Help

    - by Karem
    I am out of my own "ideas" going through this. I have a album viewer. When you click next I want the adressbar to hang with it, e.g if you start on ?photoid=1, and click next (next picture appends and stuff), and then i want it to say ?photoid=2. Now I cant make it say ?photoid=2 without changing/manipulating, and this you cant do without HTML5. I have made a script in HTML5 that works fine, but then I need to take care of those who dont have HTML5(only chrome, ff4 etc supports html5) Made the script from this( https://developer.mozilla.org/en/DOM/Manipulating_the_browser_history ) I thought of adding #photoid=2 so, ?photoid=1#photoid=2 and then check if theres anything in # then use that instead of the $_GET.. But apparently you cannot do that as # is client side handled and never sent to the server. So what should I then do? Any suggestions please to make a workaround this? I checked facebook, what they did to IE users, and I could hear that it "clicked" (the annoying click sound from IE) twice.. the first was to get to the next picture, the second click sound changed the adressbar?!(how?). And then I also thought hey, html5 is only supported in ff4, and I got ff3.6, and they manipulate the adress bar url when you browse through the album photos, exactly like how I wanted (and what I have written for but it only works in Chrome and ff4..?). How could they do that?

  • AngularJS: Using Shared Service(with $resource) to share data between controllers, but how to define callback functions?

    - by shaunlim
    Note: I also posted this question on the AngularJS mailing list here: https://groups.google.com/forum/#!topic/angular/UC8_pZsdn2U Hi All, I'm building my first AngularJS app and am not very familiar with Javascript to begin with so any guidance will be much appreciated :) My App has two controllers, ClientController and CountryController. In CountryController, I'm retrieving a list of countries from a CountryService that uses the $resource object. This works fine, but I want to be able to share the list of countries with the ClientController. After some research, I read that I should use the CountryService to store the data and inject that service into both controllers. This was the code I had before: CountryService: services.factory('CountryService', function($resource) { return $resource('http://localhost:port/restwrapper/client.json', {port: ':8080'}); }); CountryController: //Get list of countries //inherently async query using deferred promise $scope.countries = CountryService.query(function(result){ //preselected first entry as default $scope.selected.country = $scope.countries[0]; }); And after my changes, they look like this: CountryService: services.factory('CountryService', function($resource) { var countryService = {}; var data; var resource = $resource('http://localhost:port/restwrapper/country.json', {port: ':8080'}); var countries = function() { data = resource.query(); return data; } return { getCountries: function() { if(data) { console.log("returning cached data"); return data; } else { console.log("getting countries from server"); return countries(); } } }; }); CountryController: $scope.countries = CountryService.getCountries(function(result){ console.log("i need a callback function here..."); }); The problem is that I used to be able to use the callback function in $resource.query() to preselect a default selection, but now that I've moved the query() call to within my CountryService, I seemed to have lost what. What's the best way to go about solving this problem? Thanks for your help, Shaun

  • Benefits of "Don't Fragment" on TCP Packets?

    - by taspeotis
    One of our customers is having trouble submitting data from our application (on their PC) to a server (different geographical location). When sending packets under 1100 bytes everything works fine, but above this we see TCP retransmitting the packet every few seconds and getting no response. The packets we are using for testing are about 1400 bytes (but less than 1472). I can send an ICMP ping to www.google.com that is 1472 bytes and get a response (so it's not their router/first few hops). I found that our application sets the DF flag for these packets, and I believe a router along the way to the server has an MTU less than/equal to 1100 and dropping the packet. This affects 1 client in 5000, but since everybody's routes will be different this is expected. The data is a SOAP envelope and we expect a SOAP response back. I can't justify WHY we do it, the code to do this was written by a previous developer. So... Are there are benefits OR justification to setting the DF flag on TCP packets for application data? I can think of reasons it is needed for network diagnostics applications but not in our situation (we want the data to get to the endpoint, fragmented or not). One of our sysadmins said that it might have something to do with us using SSL, but as far as I know SSL is like a stream and regardless of fragmentation, as long as the stream is rebuilt at the end, there's no problem. If there's no good justification I will be changing the behaviour of our application. Thanks in advance.

  • MySql ODBC connection in VB6 on WinXP VERY slow. Other machines on same network are fast.

    - by Matthew
    Hi All, I have a VB6 application that has been performing very well. Recently, we upgraded our server to a Windows 2003 server. Migration of the databases and shares went well and we experienced no problems. Except one. And it has happened at multiple sites. I use the MySQL ODBC 5.1 connector to point to my MySQL database. On identical machines (as far as I can tell, they are client machines not ours), access to the DB is lightning fast on all but one computer. They use the same software and have the same connection strings. And I'm sure it's not the program, but the ODBC connection. When I press the 'Test Connection' button in the ODBC connection string window, it can take up to 10 seconds on the poorly performing machine to respond with a success. All the other computers are instantaneous. I have tried using ip address versus the machine name in the UDL, no change. I enabled option 256, which sped it up initially, but it's slow again. Most of the time on a restart the program will be fast for an hour or so then go slow again with the option 256 enabled. Frankly, I am out of ideas and willing to entertain any and all ideas or suggestions. This is getting pretty frustrating. Anyone ever experience anything like this?

  • C#/.NET: FInd out whether a server exists, Query DNS for SVC records.

    - by TomTom
    Writing a cleint/Server tool I am tasked trying to find a server to connect to. I would love to make things as easy as possible for the user. As such, my idea is to: CHeck whether specific servers (coded by name) exist (like "mail.xxx" for a mail server, for example - my exampüle is not a mail server;) Query otherwise for DNS SVC records, allowing the admin to configure a server location for a specific serivce (that the client connects to). The result is that the user may have to enter only a domain name, possibly even not even that (using the registered standard domain of the computer in a LAN environment). Anyone ideas how: To find out whether a server exists and answers (i.e. is online) in the fastest way? TCP can take a long time if the server is not there. A UDP style ping sounds like a good idea to me. PING itself may be unavailable. Anyonw knows how to ask from withint .NET best for a SVC record in a specific (the default) domain?

  • Visual SourceSafe (VSS): "Access to file (filename) denied" error

    - by tk-421
    Hi, can anybody help with the above SourceSafe error? I've spent hours trying to find a fix. I've also Googled the heck out of it but couldn't find a scenario matching mine, because in my case only a few files (not all) are affected. Here's what I found: only a few files in my project generate this error other files in the same directory (for example, App_Code has one of the problem files) work fine I've tried checking out from both the VSS client and Visual Studio another developer can check out the main problem file without any problems This sounds like a permission issue for my user, right? However: I found the location of one of the problem files in VSS's data directory (using VSS's naming format, as in 'fddaaaaa.a') and checked its permissions; everything looks fine and its permissions match those of other files I can check out successfully I can see no differences in the file properties between working and non-working files What else can I check? Has anyone encountered this problem before and found a solution? Thanks. P.S.: SourceGear, svn or git are not options, unfortunately. P.P.S.: Tried unsuccessfully to add tag "sourcesafe." EDIT: Hey Paddy, I tried to click 'add comment' to respond to your comment, but I'm getting a javascript error when loading this page in IE8 ("jquery undefined," etc.) so this isn't working. This is when checking out files, and yes, I've obliterated my local copy more times than I can remember. ;) EDIT 2: Thanks for the responses, guys (again I can't 'add comment' due to jQuery not loading, maybe blocked as discussed in Meta). If the problem was caused by antivirus or a bad disk, would other users still be able to check out the file(s)? That's the case here, which makes me think it's a permission issue specific to my account. However I've looked at the permissions and they match both other users' settings and settings on other files which I can check out.

  • Flash Player: Any remedy for the stale video image data problem (in a reused NetStream object)?

    - by amn
    Has anyone experienced stale stills of a previous playback for a reused NetStream object? If so, what are the workarounds for this, except re-creating the object (which eats performance and time)? It is hard to reuse NetStream objects because of a (in my opinion) fundamental issue with NetStream objects - when you 'close' a playing stream and at a later point issue a 'play' call on it again with a different name, the stream appears to still contain a stale image lingering from previous playback, and this is of course displayed in the Video object for a moment - the moment I assume it takes for new stream data to become available from server. Because of this behavior, to improve my users' visual experience, I simply discard a NetStream object after a playback session, and assign a new NetStream object to the same variable, set it up, and play something else. It appears to work - no stale image - but what bugs me is that it's a work around and costs performance (construction and setting up the object again - event listeners and 'client' delegates and more memory usage - NetStream objects are not garbage collected immediately, it takes some time). It would be really nice to REALLY be able to reuse a stream. I am thinking of something akin to Video.clear method, but for the NetStream class. Am I missing something?

  • Website. VoteUp or VoteDown Videos. How to restrict users voting multiple times?

    - by DJDonaL3000
    Im working on a website (html,css,javascript, ajax, php,mysql), and I want to restrict the number of times a particular user votes for a particular video. Its similar to the YouTube system where you can voteUp or voteDown a particular video. Each vote involves adding a row to the video.votes table, which logs the time, vote direction(up or down), the client IPaddress( using PHP: $ip = $_SERVER['REMOTE_ADDR']; ), and of course the ID of the video in question. Adding votes is as simple as; (pseudocode): Javascript:onClick( vote( a,b,c,d ) ), which passes variables to PHP insertion script via ajax, and finally we replace the voteing buttons with a "Thank You For Voting" message. THE PROBLEM: If you reload/refresh the page after voting, you can vote again, and again, and again, you get the point. MY QUESTION: How do you limit the amount of times a particular user votes for a particular video?? MY THOUGHTS: Do you use cookies, and add a new cookie with the id of the video. And check for a cookie before you insert a new vote.? OR Before you insert the vote, do you use the IPaddress and the videoID to see if this same user(IP) has voted for this same video(vidID) in the past 24hrs(mktime), and either allow or dissallow the voteInsertion based on this query? OR Do you just not care? Take the assumption that most users are sane, and have better things to do than refresh pages and vote repeatedly.?? Any suggestions or ideas welcome.

  • Is there any possibility of rendering differences betweeen firefox 3 and 3.5 and IE 7 and 8, even if

    - by metal-gear-solid
    I'm making a site for European client and he said Firefox 3 and IE 7 and 8 has more user than others browser for desktop in Europe http://gs.statcounter.com/#browser_version-eu-monthly-200812-201001-bar I've only IE 7 and Firefox 3.5.7 installed in my PC. Should I download portable Firefox 3.0 and test in it too even if I'm not using any new css property/selector which only has support in Firefox 3.5 or testing in 3.5.7 would be enough? And for IE testing in IE 7 would be enough or should i check my site in IE8 (downloading VPC image of IE8 and testing in VM) even if I'm not using any new css property/selector which only has support in IE8? Or is it necessary to use <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" /> in <head> ? But what will happen when user will switch compatibility mode to IE 8 default rendering mode? Can we make site compatible in IE 7 and 8 both without using <meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />? If yes, then what special we need to do.care/consider in css to make site identical in both?

  • VB6 ActiveX exe - what is the proper registration sequence?

    - by Timbuck
    I have recently updated a Visual Basic 6 application that is an ActiveX exe, running on Windows XP. I have a couple of testers for this application who have received a copy of the exe and are attempting to run it. However, they are getting an error message "Unexpected error;quitting" when trying to do so. A key difference between their testing and my testing is that on the machines I tested on, I have admin rights and was able to register the application using the appname.exe /regserver command line. Reading the details at MS Support about file registration appears unclear: Visual Basic ActiveX EXE files register themselves the first time you run the EXE. However, you cannot use the EXE as a COM server until it is registered. So does this mean that after the first time the users run the exe that the application should be correctly registered, and the error I am receiving is sign of something other than an incorrectly registered application? Or does this mean that the application will not work properly until such time as the file is explicitly registered using the appname.exe /regserver command line? nb - during a production distribution, the software would be sent out to client PCs using Systems Management Server, which isn't an option for this testing.

  • Fasted way to develop data entry screens for a .NET backend ?

    - by jay23
    I am a .NET / C# back end guy. I am working on a app that will have about 200 different data entry screens. For me exposing DTO as a collection for CRUD (IUpdatable and IQueryable) is the easy part, can do it in sleep :-). What I am trying to decide is what type of front end technology will allow me to develop these data entry screens fast. They don't have to be fancy but they are not just plain grid either and on average they have about 15 form fields and some client side data validation (no db look up) Options I am looking at are Use ExtJS on the front and REST / JSON on the back. ASP.NET RIA but I do not know SL (Well XAML) Plain ASP.NET / MVC One idea I had was the DTO will contain the meta data about the form (As Attributes) and the form can be dynamically generated, but i do not want to reinvent the wheel if their is an easy way. I have looked at RAD software but all of them look at the DB and generate screens. I rather want some thing that can look at my DTO and generate screens. Jay

  • Sorting in Lua, counting number of items

    - by Josh
    Two quick questions (I hope...) with the following code. The script below checks if a number is prime, and if not, returns all the factors for that number, otherwise it just returns that the number prime. Pay no attention to the zs. stuff in the script, for that is client specific and has no bearing on script functionality. The script itself works almost wonderfully, except for two minor details - the first being the factor list doesn't return itself sorted... that is, for 24, it'd return 1, 2, 12, 3, 8, 4, 6, and 24 instead of 1, 2, 3, 4, 6, 8, 12, and 24. I can't print it as a table, so it does need to be returned as a list. If it has to be sorted as a table first THEN turned into a list, I can deal with that. All that matters is the end result being the list. The other detail is that I need to check if there are only two numbers in the list or more. If there are only two numbers, it's a prime (1 and the number). The current way I have it does not work. Is there a way to accomplish this? I appreciate all the help! function get_all_factors(number) local factors = 1 for possible_factor=2, math.sqrt(number), 1 do local remainder = number%possible_factor if remainder == 0 then local factor, factor_pair = possible_factor, number/possible_factor factors = factors .. ", " .. factor if factor ~= factor_pair then factors = factors .. ", " .. factor_pair end end end factors = factors .. ", and " .. number return factors end local allfactors = get_all_factors(zs.param(1)) if zs.func.numitems(allfactors)==2 then return zs.param(1) .. " is prime." else return zs.param(1) .. " is not prime, and its factors are: " .. allfactors end

  • Get href tags in html data in c#

    - by Nani
    I am using web client class to HTML data from a web page. Now I want to get the complete href tags and there titles from the HTML data. Initially I used loops, Felling inefficient I switched to regExp, but dint got efficient solution. He is the initial code: for (int i = 0; i < htmldata.Length - 5; i++) { if (htmldata.Substring(i, 5) == "href=") { n1 = htmldata.Substring(i + 6, htmldata.Length - (i + 6)).IndexOf("\""); Sublink = htmldata.Substring(i + 6, n1); var absoluteUri = new Uri(baseUri, temp); n2 = htmldata.Substring(i + n1 + 1, htmldata.Length - (i + n1 + 1)).IndexOf("<"); subtitle = htmldata.Substring(i + 6 + n1 + 2, n2 - 7); } } This code is getting some of the links like this. /l.href.replace(new RegExp( /advanced_search?hl=en&q=&hl=en& and titles like this onclick=gbar.qs(this) class=gb2Photos ")+"q="+encodeURIComponent(b)})}i.qs=n;function o(a,b,d,c,f,e){var g=document.getElementById(a);if(g){var Which are absolutely invalid. Please suggest me the correct code for getting valid relative href links and titles. ThankYou.

  • Can JQuery.Validate plugin prevent submission of an Ajax form

    - by berko
    I am using the JQuery form plugin (http://malsup.com/jquery/form/) to handle the ajax submission of a form. I also have JQuery.Validate (http://docs.jquery.com/Plugins/Validation) plugged in for my client side validation. What I am seeing is that the validation fails when I expect it to however it does not stop the form from submitting. When I was using a traditional form (i.e. non-ajax) the validation failing prevented the form for submitting at all.... which is my desired behaviour. I know that the validation is hooked up correctly as the validation messages still appear after the ajax submit has happened. So what I am I missing that is preventing my desired behaviour? Sample code below.... <form id="searchForm" method="post" action="/User/GetDetails"> <input id="username" name="username" type="text" value="user.name" /> <input id="submit" name="submit" type="submit" value="Search" /> </form> <div id="detailsView"> </div> <script type="text/javascript"> var options = { target: '#detailsView' }; $('#searchForm').ajaxForm(options); $('#searchForm').validate({ rules: { username: {required:true}}, messages: { username: {required:"Username is a required field."}} }); </script>

  • How to provide warnings during validation in ASP.NET MVC?

    - by Alex
    Sometimes user input is not strictly invalid but can be considered problematic. For example: A user enters a long sentence in a single-line Name field. He probably should have used the Description field instead. A user enters a Name that is very similar to that of an existing entity. Perhaps he's inputting the same entity but didn't realize it already exists, or some concurrent user has just entered it. Some of these can easily be checked client-side, some require server-side checks. What's the best way, perhaps something similar to DataAnnotations validation, to provide warnings to the user in such cases? The key here is that the user has to be able to override the warning and still submit the form (or re-submit the form, depending on the implementation). The most viable solution that comes to mind is to create some attribute, similar to a CustomValidationAttribute, that may make an AJAX call and would display some warning text but doesn't affect the ModelState. The intended usage is this: [WarningOnFieldLength(MaxLength = 150)] [WarningOnPossibleDuplicate()] public string Name { get; set; } In the view: @Html.EditorFor(model => model.Name) @Html.WarningMessageFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) So, any ideas?

  • Insert only adds upto 1000 records and ignoresall records after that.

    - by user560559
    i have a large database where the client stores personal messages and fire email notifications [if allowed by the users]. certain users have the option of sending messages to their entire network of friends. some users have over 5000 friends in their network so if they select the whole network they'll be sending messages to over 5000 friends and system will store all the messages into a table. the problem is this that it does not insert more than 1000 records and ignores all inserts after the first 1000. i have increased the packet size, bulk_insert_buffer_size but still no luck. since the system stores some of the info in another table for reports, every insert returns its new message id. due to this i can not use the "insert into table (column1,column2) values (value1,value2) , (value1,value2)....etc." table engine is innodb, mysql version is 5.1.3 and is hosted on amazon web services. all i want is to fix this issue of inserting more than 1000 records at a time. as mentioned earlier, it works fine but only up to 1000 records and simply ignores all the records after that. i'm using php foreach(){} to insert message for each friend and if email is available, send notification to the user. this foreach(){} also inserts the same record in another table [with only 3 columns] for generating reports.
