  • Accessing UI thread of a form?

    - by Nick Brooks
    I'm using C# and I'm making an application where a lot of UI loading must be done in background. Is it possible to do it unsafely and ignore InvalidOperationExceptions? The only way I found it to put try...catch statements around every single line of code but this will take ages as there is too much code.

    - by Rehman

  • Add the path _vti_bin/Lists.asmx to an ASP.NET MVC 2 web application

    - by Philipp Schmid
    I am trying to add the path /_vti_bin/Lists.asmx to my ASP.NET MVC 2 web application. I am registering the route as follows: routes.IgnoreRoute("{resource}.asmx/{*pathInfo}"); routes.Add(new Route("_vti_bin/Lists.asmx", new ListsHandler())); where ListHandler is defined as: public sealed class ListsHandler : IRouteHandler { #region IRouteHandler Members public IHttpHandler GetHttpHandler(RequestContext requestContext) { throw new NotImplementedException(); } #endregion } But when I start the MVC application and try to navigate to http://localhost:8888/_vti_bin/Lists.asmx, I get an HTTP 404 error, rather than an exception raised. Is this even possible in MVC? Do I need to add an Lists.asmx ASPX web service file to my project in a particular place (I cannot create the _vti_bin folder in the Visual Studio project)?

  • Visual studio won't debug into referenced DLL (from same solution)

    - by Greg
    I have a Visual studio 2008 solution, with 2 projects. A DLL, A, and a Web application, B. B has a project reference to A, and A.dll and A.pdb are being copied to B's bin/ directory. Everything is set to compile in debug mode. I can run the cassini webserver and debug web application B fine, but when I come to call a method in A.dll, pressing F11 to step into it does not step into it, it steps over it. I want to step into it. Any ideas why I might not be able to step into the source code of A?

  • ASP.NET 3.5 Web Site stopped importing System namespace by default

    - by Alexis
    I have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default. I'm having to either place a "Imports System" line at the top of each code behind, or preface everything with "System", which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default. I've already checked to see that WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config contains the <add namespace="System"/> line--it does. That was my best lead. I'm tearing my hair out. Does anyone have any suggestions?

  • ETag in Spring (ShallowEtagHeaderFilter)

    - by niklassaers
    Hi guys, I've followed http://static.springsource.org/spring/docs/3.0.2.RELEASE/spring-framework-reference/html/mvc.html#mvc-etag and put ShallowEtagHeaderFilter in my web.xml like this: <filter> <filter-name>etagFilter</filter-name> <filter-class>org.springframework.web.filter.ShallowEtagHeaderFilter</filter-class> </filter> <filter-mapping> <filter-name>etagFilter</filter-name> <servlet-name>myServlet</servlet-name> <!-- I've even tried <url-pattern>/*</url-pattern> --> </filter-mapping> But whenever I load my pages, I don't get any etag headers in my response. Any suggestions as to what might be going on? Is there any kind of ordering my filters should have? (I'm also using OpenSessionInViewFilter and DelegatingFilterProxy Cheers Nik

    - by Tom
    Hi. I have a model, called Student, which has some fields, and a OneToOne relationship with user (django.contrib.auth.User). class Student(models.Model): phone = models.CharField(max_length = 25 ) birthdate = models.DateField(null=True) gender = models.CharField(max_length=1,choices = GENDER_CHOICES) city = models.CharField(max_length = 50) personalInfo = models.TextField() user = models.OneToOneField(User,unique=True) Then, I have a ModelForm for that model class StudentForm (forms.ModelForm): class Meta: model = Student Using the fields attribute in class Meta, i've managed to show only some fields in a template. However, can I indicate which user fields to show? Something as: fields =('personalInfo','user.username') is currently not showing anything. Works with only StudentFields though/ Thanks in advance.

  • Sharepoint and SQL server Endpoint

    - by Usman Ahmad
    I created a LinkedServer on MS SQL Server 2005 pointing to my Active Directory. Nothing too fancy. Simple LinkedServer with ReadOnlyAdmin Account assigned to CONNECTAS Property. Then I created some storedprocedures to retreive some data from the LinkedServer. Again nothing too fancy. Just a few simple LDAP Queries. Then I created a SQL Endpoint to expose these stored procedures as Web services. Using Visual Studio 2008, everything is fine and dandy. It finds the endpoint, gets the list of the methods available and runs smoothly. Cool. But the Sharpeoint Add Web Service somehow doesn't work! It finds the WSDL file no prob. Retrieves the list of functions and parameterss n all but just simply doesn't run them! Any advice or where I should start checking?

  • Spring Web Service Client Tutorial or Example Required

    - by Nirmal
    Hello All... I need to jump into the Spring Web Service Project, in that I required to implement the Spring Web Service's Client Only.. So, I have already gone through with Spring's Client Reference Document. So, I got the idea of required classes for the implementation of Client. But my problem is like I have done some googling, but didn't get any proper example of both Client and Server from that I can implement one sample for my client. So, if anybody gives me some link or tutorial for proper example from that I can learn my client side implementation would be greatly appreciated. Thanks in advance...

  • .net/iis6 Limitations of the urlMappings in web.config for extensionless url rewriting

    - by ScottE
    I'm investigating a simple url rewriting setup for iis6 / net 2.0 sites. I've added a . wildcard mapping in IIS that points to the .net executable. I'm also using the urlMappings element in the web.config to add some rewritting urls. I've moved the config outside of the web.config so I can make changes to the list without forcing application restarts, like so: <urlMappings configSource="config\urlMappings.config"> </urlMappings> I'd like to allow our content management to add urls to this file so that we can have extensionless friendly urls. <add url="~/someurl" mappedUrl="index.aspx?page=123" /> This works just fine, but I'm concerned about limitations in the number of entries that I can map in the urlMappings config. I can't seem to find any documentation on this. Has anyone found any limitations? Thanks.

  • Switching from web to desktop development

    - by Dziamid
    Being a web developer (php, symfony, doctrine) for 2 years now, I was recently asked by a friend to come up with a desktop solution. So I developed a project, installed a LAMP on his machine and he is mostly happy using it now. But I'm not. It just doesn't seem right to wait for a server response from a localhost. Obviously php isn't suited for desktop development. So, my question is: what language \ framework would you advice a php programmer if he was going to develop a desktop application (something that you can install, that has it's own gui, but utilizes the similar concepts of web apps: css, javascript, orm). I would like to bring up Python as a possible answer to my question. Does anyone have an experience of developing a desktop app with Python, utilizing an ORM and(or) HTML-based GUI?

  • Is there a way to put relationships/contraints into CSS?

    - by hekevintran
    In every design tool or art principle I've heard of, relationships are a central theme. By relationships I mean the thing you can do in Adobe Illustrator to specify that the height of one shape is equal to half the height of another. You cannot express this information in CSS. CSS hard-codes all values. Using a language like LESS that allows variables and arithmetic you can get closer to relationships but it's still a CSS variant. This inability in my mind is the biggest problem with CSS. CSS is supposed to be a language that describes the visual component of a Web page but it ignores relationships and contraints, ideas that are at the core of art. How possible is it to imagine a new Web design language that can express relationships and contraints that can be implemented in JavaScript using the current CSS properties?

  • Multi Action with Form design streatgy

    - by Ravi
    Hello All, I want to have a controller that can handle multiple requests. Like a UserController handling all the addUser, deleteUser, updateUser and viewUser functionality. I know that MultiActionController can be used to bundle multiple similar request into one controller. But the functionalities like addUser and updateUser involves user to enter data, which the controller need to process. Can a MultiActionController handle doSubmit kind of methods (similar to SimpleFormController). Is there any better way to handle this kind of scenario? Thanks. Ravi

  • Why don't the .net 4.0 charting controls work in Visual Studio 2010?

    - by kc
    The .net charting controls are advertised as being built into .net 4.0. However, they do not work in Visual Studio 2010 Pro or Visual Web Developer 2010 Express. I get the error, System.Web.HttpException: Error executing child request for ChartImg.axd. That sounds like the message from .net 3.5 if charting wasn't set up correctly. But the bottom of the same page says, "Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1" Does anyone know why this doesn't work?

  • jQuery / jqGrids / Submitting form data troubles...

    - by Kelso
    Ive been messing with jqgrids alot of the last couple days, and I have nearly everything the way I want it from the display, tabs with different grids, etc. Im wanting to make use of Modal for adding and editing elements on my grid. My problem that Im running into is this. I have my editurl:"editsu.php" set, if that file is renamed, on edit, i get a 404 in the modal.. great! However, with that file in place, nothing at all seems to happen. I even put a die("testing"); line at the top, so it sees the file, it just doesnt do anything with it. Below is the content. ........ the index page jQuery("#landings").jqGrid({ url:'server.php?tid=1', datatype: "json", colNames:['ID','Tower','Sector', 'Client', 'VLAN','IP','DLink','ULink','Service','Lines','Freq','Radio','Serial','Mac'], colModel:[ {name:'id', index:'id', width : 50, align: 'center', sortable:true,editable:true,editoptions:{size:10}}, {name:'tower', index:'tower', width : 85, align: 'center', sortable:true,editable:false,editoptions:{readonly:true,size:30}}, {name:'sector', index:'sector', width : 50, align: 'center',sortable:true,editable:true,editoptions:{readonly:true,size:20}}, {name:'customer',index:'customer', width : 175, align: 'left', editable:true,editoptions:{readonly:true,size:35}}, {name:'vlan', index:'vlan', width : 35, align: 'left',editable:true,editoptions:{size:10}}, {name:'suip', index:'suip', width : 65, align: 'left',editable:true,editoptions:{size:20}}, {name:'datadl',index:'datadl', width:55, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from datatypes"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'dataul', index:'dataul', width : 55, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from datatypes"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'servicetype', index:'servicetype', width : 85, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from servicetype"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'voicelines', index:'voicelines', width : 35, align: 'center',editable:true,editoptions:{size:30}}, {name:'freqname', index:'freqname', width : 35, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from freqband"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'radioname', index:'radioname', width : 120, editable: true,edittype:"select",editoptions:{value:"<? $qr = qquery("select * from radiotype"); while ($q = ffetch($qr)) {echo "$q[id]:$q[name];";}?>"}}, {name:'serial', index:'serial', width : 100, align: 'right',editable:true,editoptions:{size:20}}, {name:'mac', index:'mac', width : 120, align: 'right',editable:true,editoptions:{size:20}} ], rowNum:20, rowList:[30,50,70], pager: '#pagerl', sortname: 'sid', mtype: "GET", viewrecords: true, sortorder: "asc", altRows: true, caption:"Landings", editurl:"editsu.php", height:420 }); jQuery("#landings").jqGrid('navGrid','#pagerl',{edit:true,add:true,del:false,search:false},{height:400,reloadAfterSubmit:false},{height:400,reloadAfterSubmit:false},{reloadAfterSubmit:false},{}); now for the editsu.php file.. $operation = $_REQUEST['oper']; if ($operation == "edit") { qquery("UPDATE customers SET vlan = '".$_POST['vlan']."', datadl = '".$_POST['datadl']."', dataul = '".$_POST['dataul']."', servicetype = '".$_POST['servicetype']."', voicelines = '".$_POST['voicelines']."', freqname = '".$_POST['freqname']."', radioname = '".$_POST['radioname']."', serial = '".$_POST['serial']."', mac = '".$_POST['mac']."' WHERE id = '".$_POST['id']."'") or die(mysql_error()); } Im just having a hard time troubleshooting this to figure out where its getting hung up at. My next question after this would be to see if its possible to make it so when you click "add", that it auto inserts a row into the db with a couple variable predtermined and then bring up the modal window, but ill work on the first problem first. thanks!

  • Building a GPS Tracking Web System

    - by zakaria
    Hi everybody, I'd like to develop a tracking system using an API of course (like the famous Orange API). the idea is simple: I send a SMS (from my Web interface) to the person i want to track The person's mobile terminal (GPS like this) send me back automatically the coordinates by SMS. The sent information are displayed on the user's web interface. The questions are simple: How the terminal can send automatically the response? How to indicate in the message that the information is for "user4655"? How to make connection between the information and the database? Thanks, Regards.

  • Auto refresh web page

    - by Epitaph
    I have a web page which allows the user to carry out various operations that in turn modify the database. Also, this web application needs to keep track of various fields in database that keep changing with time. Is refreshing the page every few seconds the best possible way to implement this? For example, if there is a long list on the page requiring scrolling, it is hard to view the list since the page keeps resetting due to the refresh. I know, there are ways to retain the position of the scroll. But, could I use something more efficient?

  • Is it normal for a programmer with 2 years experience to take a long time to code simple programs?

    - by ajax81
    Hi all, I'm a relatively new programmer (18 months on the scene), and I'm finally getting to the point where I'm comfortable accepting projects and developing solutions under minimal supervision. Unfortunately, this also means that I've become acutely aware of my performance shortfalls, the most prevalent of which is the amount of time it takes me to develop, test, and submit algorithms for review. A great example of what I'm talking about occurred this week when I was tasked with developing a simple XML web service (asp.net 3.5) callable via client-side JavaScript, that accepts a single parameter and returns a dataset output to a modal window (please note this is the first time I've had to develop a web service and have had ZERO experience creating/consuming them...let alone calling them from JS client side). Keeping a long story short -- I worked on it for 4 days straight, all day each day, for a grand total of 36 hours, not including the time I spent dwelling on the problem in the shower, the morning commute, and laying awake in bed at night. I learned a great deal about web services and xml/json/javascript...but was called in for a management review to discuss the length of time it took me to develop the solution. In the meeting, I was praised for the quality of my work and was in fact told that my effort was commendable. However, they (senior leads and pm's) weren't impressed with the amount of time it took me to develop the solution and expressed that they would have liked to see the solution in roughly 1/3 of the time it took me. I guess what concerns me the most is that I've identified this pattern as common for myself. Between online videos, book research, and trial/error coding...if its something I haven't seen before, I can spend up to two weeks on a problem that seems to only take the pros in the videos moments to code up. And of course, knowing that management isn't happy with this pattern has shaken me up a bit. To sum up, I have some very specific questions I'd like to ask, and would greatly appreciate your objective professional feedback. Is my experience as a junior programmer common among new developers? Or is it possible that I'm just not cut out for the work? If you suspect that my experience is not common and that there may be an aptitude issue, do you have any suggestions/solutions that I could propose to management to help bring me up to speed? Do seasoned, professional programmers ever encounter knowledge barriers that considerably delay deliverables? When you started out in the industry, did you know how to "do it all"? If not, how long did it take you to be perceived as "proficient"? Was it a natural progression of trial and error, or was there a particular zen moment when you knew you had achieved super saiyen power level? Anyways, thanks for taking the time to read my question(s). I don't know if this is the right place to ask for professional career guidance, but I greatly appreciate your willingness to help me out. Cheers, Daniel

  • User Interface design books/resources for programmers

    - by mmacaulay
    Hi, I'm going to make my monthly trip to the bookstore soon and I'm kind of interested in learning some user interface and/or design stuff - mostly web related, what are some good books I should look at? One that I've seen come up frequently in the past is Don't Make Me Think, which looks promising. I'm aware of the fact that programmers often don't make great designers, and as such this is more of a potential hobby thing than a move to be a professional designer. I'm also looking for any good web resources on this topic. I subscribed to Jakob Nielsen's Alertbox newsletter, for instance, although it seems to come only once a month or so. Thanks! Somewhat related questions: http://stackoverflow.com/questions/75863/what-are-the-best-resources-for-designing-user-interfaces http://stackoverflow.com/questions/7973/user-interface-design
