  • .NET Webservice Client: Auto-retry upon call failure

    - by Yon
    Hi, We have a .NET client calling a Java webservice using SSL. Sometimes the call fails due to poor connectivity (the .NET Client is a UI that is used from the weirdest locations). We would like to implement an automatic retry mechanism that will automatically retry a failed call X times before giving up. This should be done solely with specific types of connectivity exceptions (and not for exceptions generated by the web service itself). We tried to find how to do it on the Binding/Channel level, but failed... any ideas? Thanks, yonadav

  • Pass client side js variable into server side jscript

    - by George
    How can I get the query string from the browser url using client side js and set it as a variable to use in some server side scripting? Client side script: var project = getQueryString("P"); function getQueryString(param) { var queryString = window.location.search.substring(1); splitQueryString = queryString.split("&"); for (i=0; i<splitQueryString.length; i++) { query = splitQueryString[i].split("="); if (query[i] == param) { return query[1]; } } } Server side script: response.write ('<td><a href="/index.asp?P=' + project + ">' + obj.BODY[i].NAME + '</a></td>');

  • NLog not logging messages on XP SP3 with .NET 3.5 Client Profile

    - by oltman
    I'm writing a program that is targeting the .NET 3.5 Client Profile and using NLog. I configure my logger programmatically on start up (no config file.) It works perfectly on Vista and Windows 7, but when running on a fresh install of XP SP3 with the .NET Client Profile installed, it will not log any of the variables in the layout string. For example, with the layout string set to: target.Layout = "MESSAGE: ${longdate}|${level}|${message}"; It will log "MESSAGE: | | |" Again, this only happens on XP SP3, and the logger is set to throw exceptions. Any ideas what may be causing this?

  • ASP.NET MVC 2: Custom client side validation rule for dropdowns

    - by Nigel
    I have some custom validation that I need to perform that involves checking the selected option of a dropdown and flagging it as invalid should the user select a specific option. I am using ASP.NET MVC 2 and have a custom Validator and custom server side and client side validation rules as described in this blog article. The server side validation is working fine, however, the client side validation is failing. Here is the javascript validation rule: Sys.Mvc.ValidatorRegistry.validators["badValue"] = function(rule) { var badValue = rule.ValidationParameters["badValue"]; return function(value, context) { if (value != badValue) { return true; } return rule.ErrorMessage; }; }; The rule is being applied to the dropdowns successfully, and placing a breakpoint within the returned function confirms that the validation is firing, and that the 'badValue' is being correctly set. However, 'value' is always null, and so the check always fails. What am I doing wrong?

  • Passing Custom headers from .Net 1.1 client to a WCF service

    - by sreejith
    I have a simple wcf service which uses basicHttp binding, I want to pass few information from client to this service via custom SOAP header. My client is a .net application targetting .Net 1.1, using visual studio I have created the proxy( Added a new web reference pointing to my WCF service) I am able to call methods in the WCF service but not able to pass the data in message header. Tried to override "GetWebRequest" and added custom headers in the proxy but for some reason when I tried to access the header using "OperationContext.Current.IncomingMessageHeaders.FindHeader" it is not thier. Any idea how to solve this prob? This is how I added the headers protected override System.Net.WebRequest GetWebRequest(Uri uri) { HttpWebRequest request; request = (HttpWebRequest)base.GetWebRequest(uri); request.Headers.Add("tesData", "test"); return request; }

  • Server database -> client database update based on version

    - by user296191
    Hi, What is the recommended method of collecting items in a server database, versioning the database then deploying only the version differences to a client ? Should it by a field in the table (ie. Version: 3.3.9876) against each record ? Should it be DateTime (server based) in each record ? And whats the best way to just deploy the changes to a client with an older version of the database ? Is it a DUMP to a file with a Bulk import of some description ? Open to comments.. Suggestions. Database can be anything (firebird, mysql, sqlserver, sqlite)... Any info greatly appreciated.

  • Client side templating with unknown variables

    - by Eirik Johansen
    Our company has an intranet consisting of several e-mail templates filled with variables (like [[NAME]], [[PROJECT]] and so on). I was thinking of implementing some sort of client side templating to make it easier to replace these variables with actual values. The problem is that among all the client side template solutions I've located so far, all of them seem to assume that the JS code knows all the template variables that exist in the markup, and none of them seem to be able to fetch a list of variables defined in the markup. Does anyone know of any solutions/plugin which makes this possible? Thanks in advance!

  • Accessing HTTP status code while using WCF client for accessing RESTful services

    - by Hemant
    Thanks to this answer, I am now able to successfully call a JSON RESTful service using a WCF client. But that service uses HTTP status codes to notify the result. I am not sure how I can access those status codes since I just receive an exception on client side while calling the service. Even the exception doesn't have HTTP status code property. It is just buried in the exception message itself. So the question is, how to check/access the HTTP status code of response when the service is called.

  • Remote Control software for Mac

    - by MarqueIV
    One of the things I like about Microsoft's RDC Client is that the resolution of the experience is set by the client and not, say, a physical monitor connected to the host, as is the case with VNC; the latter being the protocol used by Mac. This means that even though I'm connecting to a notebook with a 1280x800 physical resolution, via RDC I can run it at 2560x1600 on my 30" monitor. However, that only seems to work for RDC. Does anyone know of something I can run on the Mac that will allow me to remotely control it at a different resolution than what is physically set? TIA, Mark

  • CSSOMParser in gwt client side

    - by Zoja
    What i would like to do is to read an css file from a GET request on the client side, and then i would like to parse it to check all the classes. The problem is that I need to implement CSSOMParser for that, and here are the imports import org.w3c.dom.css.CSSRule; import org.w3c.dom.css.CSSRuleList; import org.w3c.dom.css.CSSStyleRule; import org.w3c.dom.css.CSSStyleSheet; import com.steadystate.css.parser.CSSOMParser; the problem is that none of those classes ale probably javascript compilant, so they don't want to compile if they're on the client side. Is there a way to get it done ?

  • How to: WCF XML-RPC client?

    - by mr.b
    I have built my own little custom XML-RPC server, and since I'd like to keep things simple, on both server and client side, what I would like to accomplish is to create a simplest possible client (in C# preferably) using WCF. Let's say that Contract for service exposed via XML-RPC is as follows: [ServiceContract] public interface IContract { [OperationContract(Action="Ping")] string Ping(); // server returns back string "Pong" [OperationContract(Action="Echo")] string Echo(string message); // server echoes back whatever message is } So, there are two example methods, one without any arguments, and another with simple string argument, both returning strings (just for sake of example). Service is exposed via http. Aaand, what's next? :) P.S. I have tried googling around for samples and similar, but all that I could come up with are some blog-related samples that use existing (and very big/numerous) classes, which implement appropriate IContract (or IBlogger) interfaces, so that most of what I am interested is hidden below several layers of abstraction...

  • MVC2 Client-Side Validation for injected Ajax response

    - by radu-negrila
    Hi, I have the following scenario for an MVC 2 website. The user checks a radio. I make a jQuery GET to retrieve some html (partial view + view model). The view-model is annotated with validation attributes. I need client-side validation for the new html's inputs. I tried placing the following line in the partial view: <% Html.EnableClientValidation(); % I was naive. Also for the obtained html I use jQuery's .html to populate my placeholder, which also would execute the javascript. Not that there is any. Is is possible to update the page's validation logic and metadata after the ajax call ? Any ideas (beside remote client side validation) ? Thanks in advance.

  • FTP client to zip before upload and unzip on the server after upload

    - by Ronaldo Junior
    I am always working with some big websites that is annoying to upload given the number of small files. I use Filezilla but am happy to buy some commercial solution if there is one out there that can zip the files before upload and then unzip it after upload. Its a pain to have to manually do that all the time. If someone know of any ftp client or extension for Filezilla or other that would do that... I sent an email to the support for CuteFTP and WSFtp - no answer so far... I know FTP protocol does not allow this command - thats why Im asking for a extension (if anyone know) or a free or commercial FTP client that do the job...

  • MVC3/Razor Client Validation Not firing

    - by Jason Gerstorff
    I am trying to get client validation working in MVC3 using data annotations. I have looked at similar posts including this MVC3 Client side validation not working for the answer. I'm using an EF data model. I created a partial class like this for my validations. [MetadataType(typeof(Post_Validation))] public partial class Post { } public class Post_Validation { [Required(ErrorMessage = "Title is required")] [StringLength(5, ErrorMessage = "Title may not be longer than 5 characters")] public string Title { get; set; } [Required(ErrorMessage = "Text is required")] [DataType(DataType.MultilineText)] public string Text { get; set; } [Required(ErrorMessage = "Publish Date is required")] [DataType(DataType.DateTime)] public DateTime PublishDate { get; set; } } My cshtml page includes the following. <h2>Create</h2> <script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script> <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> @using (Html.BeginForm()) { @Html.ValidationSummary(true) Post <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.Text) </div> <div class="editor-field"> @Html.EditorFor(model => model.Text) @Html.ValidationMessageFor(model => model.Text) Web Config: <appSettings> <add key="ClientValidationEnabled" value="true" /> <add key="UnobtrusiveJavaScriptEnabled" value="true" /> Layout: <head> <title>@ViewBag.Title</title> <link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" /> <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")" type="text/javascript"></script> So, the Multiline Text annotation works and creates a text area. But none of the validations work client side. I don't know what i might be missing. Any ideas?? i can post more information if needed. Thanks!

  • Solutions for redundant server and client code?

    - by Fragsworth
    In our system, the code which exists on the client side (in Flash and Javascript) mirrors the code that exists on the server side (e.g. in Python or PHP), normally with respect to the models, the methods available for those models, and the unit tests written for them. This becomes a problem in systems where you want to minimize data transfer (e.g. multiplayer games). I do not want to write the same code and unit tests redundantly for both the client and server, but I don't know of any standard solutions to deal with this. Basically, I want a language/compiler which can produce models and methods for three main languages: Actionscript, Javascript, and any server language. Does something like this exist?

  • Strategies for "Always-Connected" Windows Client Data Architecture

    - by magz2010
    Hi. Let me start by saying: this is my 1st post here, this is a bit lenghty, and I havent done Windows Forms development in years....with that in mind please excuse me if this isn't directly a programming question and please bear with me as I really need the help!! I have been asked to develop a Windows Forms app for our company that talks to a central (local area network) Linux Server hosting a PostgreSQL database. The app is to allow users to authenticate themselves into the system and thereafter conduct the usual transactions with the PG database. Ordinarily, I would propose writing a webforms app against Mono, but the clients need to utilise local resources such as USB peripheral devices, so that is out of the question. While it might not seem clear, my questions are italised below: Dilemma #1: The application is meant to be always connected. How should I structure my DAL/BLL - Should this reside on the server or with the client? Dilemma #2: I have been reading up on Client Application Services (CAS), and it seems like a great fit for authentication, as everything is exposed via URIs. I know that a .NET Data Provider exists for PostgreSQL, but not too sure if CAS will all work on a Linux (Debian) server? Believe me, I would get my hands dirty and try myself, but I need to come up with a logical design first before resources are allocated to me for "trial purposes"! Dilemma #3: If the DAL/BLL is to reside on the server, is there any way I can create data services, and expose only these services to authenticated clients. There is a (security) requirement whereby a connection string with username and password to the database cannot be present on any client machines...even if security on the database side is quite rigid. I'm guessing that the only way for this to work would be to create the various CRUD data service methods that are exposed by an ASP.NET app, and have the WindowsForms make a request for data or persist data to the ASP.NET app (thru a URI) and have that return a resultset or value. Would I be correct in assuming this? Should I be looking into WCF Data Services? and will WCF work with a non-SQL Server database? Thank you for taking the time out to read this, but know that I am desperately seeking any advice on this! THANKS A MILLION!!!!

  • SQL Native Client 10 Performance miserable (due to server-side cursors)

    - by namezero
    we have an application that uses ODBC via CDatabase/CRecordset in MFC (VS2010). We have two backends implemented. MSSQL and MySQL. Now, when we use MSSQL (with the Native Client 10.0), retrieving records with SELECT is dramatically slow via slow links (VPN, for example). The MySQL ODBC driver does not exhibit this nasty behavior. For example: CRecordset r(&m_db); r.Open(CRecordset::snapshot, L"SELECT a.something, b.sthelse FROM TableA AS a LEFT JOIN TableB AS b ON a.ID=b.Ref"); r.MoveFirst(); while(!r.IsEOF()) { // Retrieve CString strData; crs.GetFieldValue(L"a.something", strData); crs.MoveNext(); } Now, with the MySQL driver, everything runs as it should. The query is returned, and everything is lightning fast. However, with the MSSQL Native Client, things slow down, because on every MoveNext(), the driver communicates with the server. I think it is due to server-side cursors, but I didn't find a way to disable them. I have tried using: ::SQLSetConnectAttr(m_db.m_hdbc, SQL_ATTR_ODBC_CURSORS, SQL_CUR_USE_ODBC, SQL_IS_INTEGER); But this didn't help either. There are still long-running exec's to sp_cursorfetch() et al in SQL Profiler. I have also tried a small reference project with SQLAPI and bulk fetch, but that hangs in FetchNext() for a long time, too (even if there is only one record in the resultset). This however only happens on queries with LEFT JOINS, table-valued functions, etc. Note that the query doesn't take that long - executing the same SQL via SQL Studio over the same connection returns in a reasonable time. Question1: Is is possible to somehow get the native client to "cache" all results locally use local cursors in a similar fashion as the MySQL driver seems to do it? Maybe this is the wrong approach altogether, but I'm not sure how else to do this. All we want is to retrieve all data at once from a SELECT, then never talk the server again until the next query. We don't care about recordset updates, deletes, etc or any of that nonsense. We only want to retrieve data. We take that recordset, get all the data, and delete it. Question2: Is there a more efficient way to just retrieve data in MFC with ODBC?

  • Client to access and edit a MySQL database remotely

    - by Scott
    Hey guys, So I have been given the host, username, and login information for a MySQL Database. I need a client that I can use to log in to the Database remotely and create/update tables and edit all the data. I found the MySQL Administrator client provided by them, but it seems you can do everything BUT edit the actual data with it. Is there anything like this? Would I be able to use SQL Server Express (or something similar), to connect to a remote server online and do all of this?

  • Client Profile Application prerequisites

    - by Carlo
    One last question about Client Profile installation. I downloaded the Microsoft .NET Framework Client Profile Online Installer because we want to put it in the installation CD because our end user might not have either .net framework 3.5 or internet. So we want to be able to handle both cases. In the prerequisites I'm able to select the location of where the file will be, but I don't know where it should be. I want to be able to somehow put the path of the cd, something like d:\ProductName\Prerequisites\DotNetFx35ClientSetup.exe so it can get it and install it from there. Does anyone have an idea of how this can be achieved? Thank you. Here's the prerequisites window:

  • Clickonce + .net client profile 4 framework + offline

    Hi, I have a windows form project using VS2010 and I am deploying using clickonce. I need the application to work offline as well as online. I have configured the prerequisite - .net client profile 4 and set the location to the same as the application. Everything seems to work as expected, but upon testing I have found it takes 5+ minutes to install the .net client profile 4 and it also requires a reboot. Why does it take so long to install offline (I thought this was going to be mega fast like promised? And why does it require a reboot!!!!????

  • SharePoint 2010 - Client Object Model - Add attachment to ListItem

    - by Thorben
    Hi, I have a SharePoint List to which I'm adding new ListItems using the Client Object Model. Adding ListItems is not a problem and works great. Now I want to add attachments. I'm using the SaveBinaryDirect in the following manner: File.SaveBinaryDirect(clientCtx, url.AbsolutePath + "/Attachments/31/" + fileName, inputStream, true); It works without any problem as long as the item that I'm trying to add the attachment to, already has an attachment that was added through the SharePoint site and not using the Client Object Model. When I try to add an attachment to a item that doesnt have any attachments yet, I get the following errors (both happen but not with the same files - but those two messages appear consistently): The remote server returned an error: (409) Conflict The remote server returned an error: (404) Not Found I figured that maybe I need to create the attachment folder first for this item. When I try the following code: clientCtx.Load(ticketList.RootFolder.Folders); clientCtx.ExecuteQuery(); clientCtx.Load(ticketList.RootFolder.Folders[1]); // 1 -> Attachment folder clientCtx.Load(ticketList.RootFolder.Folders[1].Folders); clientCtx.ExecuteQuery(); Folder folder = ticketList.RootFolder.Folders[1].Folders.Add("33"); clientCtx.ExecuteQuery(); I receive an error message saying: Cannot create folder "Lists/Ticket System/Attachment/33" I have full administrator rights for the SharePoint site/list. Any ideas what I could be doing wrong? Thanks, Thorben
