• Does RazorEngine require MVC3 to be installed?

  - by tkha007

  I am working on a web project that uses MVC2. I decided to try out RazorEngine to do some e-mail templating. This appeared to work fine when I was protyping using an MVC2 project so I assumed that RazorEngine will work fine for my e-mail templating solution. What I had forgotten at the time was that I actually had MVC3 installed on my local development machine. After deploying the project on a pre-test server I get the following error in the logs when the application attempts to do anything with RazorEngine: Could not load file or assembly 'System.Web.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. File name: 'System.Web.Razor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' at RazorEngine.Compilation.DefaultCompilerServiceFactory.CreateCompilerService(Language language) at RazorEngine.Templating.TemplateService.CreateTemplateType(String razorTemplate, Type modelType) at RazorEngine.Templating.TemplateService.CreateTemplate[T](String razorTemplate, T model) at RazorEngine.Templating.TemplateService.Parse[T](String razorTemplate, T model) at RazorEngine.Razor.Parse[T](String razorTemplate, T model) at System.Dynamic.UpdateDelegates.UpdateAndExecute3[T0,T1,T2,TRet](CallSite site, T0 arg0, T1 arg1, T2 arg2) at Persistence.Utility.RazorEngineHelper.Parse(String templateName, Object model) in The fact that it can't find 'System.Web.Razor' means that this DLL does not exist on the deployed server. The only difference I can think of between the deployment server and my local dev machine is that the deployment server does not have MVC3 installed but I may be mistaken because the deployment server is not something I normally control and as such I don't have a lot of information about it. It is meant to host this particular application so there have been previous deployments of this application to this server. This is the first time I'm making a deployment with RazorEngine as a dependency.

• Display web page from another site in asp page.

  - by Daniel

  hi all, Our customer has a requirement to extend the functionality of their existing large government project. It is an ASP.NET 3.5 (recently upgraded from 2.0) project. The existing solution is quite a behemoth that is almost unmaintainable so they have decided that they want to provide the new functionality by hosting it on another website that is shown within the existing website. As to how this is best to be done I'm not quite sure right now and if there is any security issues preventing it or that need to be considered. Essentially the user would log on to the existing web site as normal and when cliicking on a certain link the page would load as normal with some kind of frame or control that has within it the contents of the page from the other site. IE. They do not want to simply redirect to the other site they want to show it embedded within the current one such that the existing menus etc are still available. I believe if information needed to be passed to the embedded page it would be done using query strings as I'm not sure if there is even another way to accomplish this. Can anyone give me some pointers on where to start at looking to implement this or any potential pitfalls I should be aware of. Thanks

• NServiceBus & MSMQ: How To Change the Default Permissions on the Queue?

  - by Amy T

  My team is on our first attempt at using NServiceBus (v2.0), using MSMQ as the backing storage. We're getting stuck on queue permissions. We're using it in a Web Forms application, where the user account the website runs under is not an administrator on the machine. When NServiceBus creates the MSMQ queue, it gives the local administrators group full control, and the local everyone and anonymous groups permissions to send messages. But then later, as part of initializing the queue, NServiceBus tries to read all of its messages. That's where we run into the permissions error. Since the website isn't running as an administrator, it's not allowed to read messages. How are other people dealing with this? Do your applications run as administrators? Or do you create the MSMQ queue in your code first, giving it the permissions you need, so that NServiceBus doesn't have to create it? Or is there a bit of configuration we're missing? Or are we likely writing our code that uses NServiceBus incorrectly to be running into this?

• Use jquery ':contains' to find specific javascript within a span

  - by Rob

  This is my first time here, I hope that this is clear. So i will have code similar to this this. <span class="mediaSource ui-draggable" id="purchsePlay7915504"> <a href="" onclick="return popup_window(this, 'MediaView', 850, 680)" class="control" enter code hereid="GenericLink"></a> <img id="Any_71" alt="Media Source" src="images/9672web.gif" class="mediaStationIcons mediaWin"/> <img class="player" alt="Media Source" src="images/playmedia.gif" style="display: none;"/> </span> The href portion is generated on the backend, and I have no access to it. I need to modify some existing jquery code to do something based on what the 'onclick' function is(there are different ones e.g. popup_window1,popup_window2 etc.) . I tried something like this: $('.segmentLeft span.mediaSource').click(function(){ if ($('span:contains("popup_window")').length > 0) { do something } }); but it does not seem to work.

• Disabled input text color

  - by Incidently

  Hi The simple HTML below displays differently in Firefox and WebKit-based browsers (I checked in Safari, Chrome and iPhone). In Firefox both border and text have the same color (#880000), but in Safari the text gets a bit lighter (as if it had some transparency applied to it). Can I somehow fix this (remove this transparency in Safari)? UPDATE: Thank you for your answers. I don't need this for my work anymore (instead of disabling, I'm replacing input elements with styled div elements), but I'm still curious why this happens and if there is any way to control this behaviour ... <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <style type="text/css"> input:disabled{ border:solid 1px #880000; background-color:#ffffff; color:#880000; } </style> </head> <body> <form action=""> <input type="text" value="disabled input box" disabled="disabled"/> </form> </body> </html>

• Soap 1.2 Endpoint Performance

  - by mflair2000

  I have a Client WCF Host Service SOAP 1.2 Service setup and i'm having performance issues on the SOAP Java proxy. I have no control over how the Java service is setup, aside from the endpoint config. I have the Client running Asynchronously, and the host WCF service running in Async pattern, but i see the SOAP 1.2 proxy bottlenecking and handling the requests in a Synchronous way. Can someone take a look at the auto-generated SOAP 1.2 configuration below, from the SOAP 1.2 Service wsdl? Is there a way to configure this for Async way and improve performance?

• Best way and problems when using ajax tabs with an MVC PHP project

  - by Jonathan

  Hi, I'm building an IMDB.com like website using PHP/jQuery and a MVC approach (no OOP). I have an index.php base controller to 'rule them all' :), a controllers folder with all the controllers, a models folder and a view folder. In some pages of the website I have tabbed navigation, when the visitor clicks on one of those tabs to get more information, jQuery gets that data using the $.post or $.get method and shows it on the tab container, obviously without refreshing the page. The problem is that those pages loaded by ajax are also generated using controllers, models, and views, and the things are getting a bit complicated for someone like me ( = 'no experience'). To dynamically get the data I some times need to include a model twice, include an include in an include in an include, send information multiple times, connect with the database again, and all sort of things like that and I'm sure there is a better and prettier way to do this. I'm searching for the best approach and common methods for this. I have no experience working with a big project like this. This is a personal project so I have full control and every answer is welcome. Thanks!!!

• The type or namespace name 'WebControls' could not be found (are you missing a using directive or an assembly reference?)

  - by user1467175

  I encountered this error: The type or namespace name 'WebControls' could not be found (are you missing a using directive or an assembly reference?) Source Error: Line 28: Login Login1 = (WebControls.Login)LoginView1.FindControl("Login1"); // here the error code Line 29: TextBox UserName = (TextBox)Login1.FindControl("UserName"); Line 30: TextBox FailureText = (TextBox)Login1.FindControl("FailureText"); I did some research and the solution was to add this into the source code: System.Web.UI.WebControls.Login but I have no idea where this code can be add into. At first I tried putting it as a namespace, but it was wrong. Anyone can tell me where should I place this code at?? EDIT protected void Login1_LoginError(object sender, System.EventArgs e) { //Login Login1 = (WebControls.Login).LoginView1.FindControl("Login1"); Login Login1 = (System.Web.UI.WebControls.Login)LoginView1.FindControl("Login1"); TextBox UserName = (TextBox)Login1.FindControl("UserName"); TextBox FailureText = (TextBox)Login1.FindControl("FailureText"); //There was a problem logging in the user //See if this user exists in the database MembershipUser userInfo = Membership.GetUser(UserName.Text); if (userInfo == null) { //The user entered an invalid username...

• HTTP 401.3 when PUT, DELETE to ADO.NET Data Service (.svc)

  - by Nate

  I have an ADO.NET Data Service (we'll call it service.svc). When I deploy it to an IIS 6 site with Integrated Windows Authentication turned on, all requests (GET, POST, PUT, and DELETE) work fine for me, because I am an administrator on the box. However, when a non-admin user hits the service, only GET and POST requests work. When they try a PUT or DELETE request, they get an HTTP 401.3 "Access is Denied" error: "Error message 401.3: You do not have permission to view this directory or page using the credentials you supplied (access denied due to Access Control Lists). Ask the web server's administrator to give you access to '...\service.svc'." If I give the "Authenticated Users" local group write access to the .svc file, everything works as it should, but I really don't want to do this (and don't think I should have to do this to get this to work). In fact, I'm confused as to why changing the file permissions would affect this at all, but it definitely seems to be the problem. I've found a couple of different suggestions to fix somewhat similar problems in the Microsoft forums (Here, and I would post more links, but am being told that new users can only post one link in a post), but none of the solutions help. Any help is much appreciated. I am certainly no IIS expert, and this one has got me stumped.

• What happens to exinsting workspaces after upgrading to TFS 2010

  - by user351671

  Hi, I was looking for some insight about what happens to existing workspaces and files that are already checked-out on people, after an upgrade to TFS2010. Surprisingly enough I can not find any satisfactory information on this. (I am talking about upgrading on new hardware by the way. Fresh TFS instance, upgraded databases) I've checked TFS Installation guide, I searched through the web, all I could find is upgrade scenarios for the server side. Nobody even mentions what happens to source control clients. I've created a virtual machine to test the upgrade process, The upgrade was successful and all my files and workspaces exist in the new server too. The problem is: The new TFS installation has a new instanceID. When I redirected on the clients to the new server, the client seemed unable to match files and file states in the workspace with the ones on the new server. This makes me wonder if it will be possible to keep working after the production upgrade. As I mentioned above I can not find anything on this, it would be great if anyone could point me to some paper or blog post about this. Thanks in advance...

• Conflict with @Html.LabelFor and W3C Validator?

  - by Tyler

  I have a model that I am using to present an index of a model from a database and have given a display name to some of the rows that may need spaces in them, (I.e. "weekstarting" in a db would be given a display name of "Week Starting"). So I set the display name for my model like this: [DisplayName("Week Starting")] public DateTime WeekStarting { get; set; } and then in the table headers for my table I use the following line of code to display the field name using its given display name: @Html.LabelFor(x => x.First().WeekStarting) The above all works fine. But I am using the W3C validator and it is giving me the following error for the example I have given: The for attribute of the label element must refer to a form control. Forgive me if it is obvious but what am I doing wrong here? I am not using a form I am simply displaying an index of items in a table. I have tried to look for an answer and saw someone suggest that the form controls being referred to need ids (even though I'm not using a form) but this would not be applicable in this instance because if I tried to set an id in the index it would be duplicated with each item in the index: foreach (var item in Model.Tbms) { <tr><td>@item.value</td><tr>.... would be repeated for each item, and also unsure where I would put the id in any case, the td? } Or is there a better way to label the field header, with my preferred display name in the first place? I guess I could just swap @Html.LabelFor... for Hard code field name but do I have to?

• Length of a string in pixels

  - by Rose

  Guys, I'm populating a dropDownList with arrayCollection of strings. I want the width of the drop down list control to match with the size (in pixels) of the longest string in the array collection. The problem I'm facing is: the font width of the strings in the collection are different e.g. 'W' looks wider than 'l'. So I estimated the width of a character to be 8 pixels but that's not pretty neat. If a string that has many 'W' and 'M' is encountered the estimation is wrong. So I want precise pixel width of strings. How can i get the exact length of a string in pixels?? My solution that estimates all character to be 8 pixels wide is given below: public function populateDropDownList():void{ var array:Array = new Array("o","two","three four five six seven eight wwww"); var sampleArrayCollection:ArrayCollection = new ArrayCollection(array); var customDropDownList:DropDownList = new DropDownList(); customDropDownList.dataProvider=sampleArrayCollection; customDropDownList.prompt="Select ..."; customDropDownList.labelField="Answer Options:"; //calculating the max width var componentWidth=10; //default for each(var answerText in array){ Alert.show("Txt size: "+ answerText.length + " pixels: " + answerText.length*9); if(answerText.length * 8 > componentWidth){ componentWidth=answerText.length * 8; } } customDropDownList.width=componentWidth; answers.addChild(customDropDownList); } Any idea or solution is highly valued. Thanks

• How do I simplify my code?

  - by Mitchell Skurnik

  I just finished creating my first major application in C#/Silverlight. In the end the total line count came out to over 12,000 lines of code. Considering this was a rewrite of a php/javascript application I created 2 years that was over 28,000 lines I am actually quite proud of my accomplishment. After reading many questions and answers here on stackoverflow and other sites online, I followed many posters advice: I created classes, procedures, and such for things that I would have a year ago copied and pasted; I created logic charts to figure out complex functions; making sure there are no crazy hidden characters (used tabs instead of spaces); and a few others things; place comments where necessary (I have lots of comments). My application consists of 4 tiles laid out horizontally that have user controls loaded into each slice. You can have between one and four slices loaded at anytime. If you have once slice loaded, the slice takes up the entire artboard...if you have 2 loaded, each take up half, 3 a third, 4 a quarter. Each one of these slices represent (for the sake of this example) a light control. Each slice has 3 slider controls in it. Now when I coded the functionality of the sliders, I used a switch/case statement inside of a public function that would run the command on the specified slice/slider. The made for some duplicate code but I saw no way around it as each slice was named differently. So I would do slice1.my.commands(); slice2.my.commands(); etc. My question to you is how do I clean up my code even futher? (Sadly I cannot post any of my code). Is there any way to take this repetion out of my code?

• Execute client & server side code with one click?

  - by Abu Hamzah

  i am not sure if my design have flaw but would like to know what others have to say, i am in a situation where i am trying to acheive two things in one click. using : asp.net web form i have a web form with few textbox and a gridview control and a button. if i click on the button i am executing two things 1) asynchronously get data from server to client (working great) and able to display the data in the textboxes. 2) same click i want to bind the gridview. <asp:Content ID="Content2" ContentPlaceHolderID="cphMaster" runat="server"> <asp:Label runat="server" ID='Label1' >Id:</asp:Label> <asp:TextBox ID="txtId" runat='server'></asp:TextBox> <asp:Button ID="btnSubmit" OnClientClick="LoadDataById();" runat="server" Text="Submit" onclick="btnSubmit_Click" /> <br /> <br /> <asp:TextBox ID="txtName" runat='server'></asp:TextBox> <br /> <asp:TextBox ID="txtPurpose" runat='server'></asp:TextBox> <br /> <br /> <asp:GridView ID="GridView1" runat="server"> </asp:GridView> </asp:Content> server side protected void btnSubmit_Click(object sender, EventArgs e) { GridView1.DataSource = laodData(int.Parse(txtId.Text)); GridView1.DataBind(); } Jquery: function LoadVisitBasicByVisitId() { ContactServiceProxy.invoke({ serviceMethod: "GetDataById", data: { request: request }, callback: function(response) { processCompletedContactStore(response); }, error: function(xhr, errorMsg, thrown) { postErrorAndUnBlockUI(xhr, errorMsg, thrown); } }); return false; } recap: 1) jquery script execute asynchronously to get data from server to client and display in the textboxes 2) server side code to bind the gridview.

• recursive wget with hotlinked requisites

  - by dongle

  I often use wget to mirror very large websites. Sites that contain hotlinked content (be it images, video, css, js) pose a problem, as I seem unable to specify that I would like wget to grab page requisites that are on other hosts, without having the crawl also follow hyperlinks to other hosts. For example, let's look at this page https://dl.dropbox.com/u/11471672/wget-all-the-things.html Let's pretend that this is a large site that I would like to completely mirror, including all page requisites – including those that are hotlinked. wget -e robots=off -r -l inf -pk ^^ gets everything but the hotlinked image wget -e robots=off -r -l inf -pk -H ^^ gets everything, including hotlinked image, but goes wildly out of control, proceeding to download the entire web wget -e robots=off -r -l inf -pk -H --ignore-tags=a ^^ gets the first page, including both hotlinked and local image, does not follow the hyperlink to the site outside of scope, but obviously also does not follow the hyperlink to the next page of the site. I know that there are various other tools and methods of accomplishing this (HTTrack and Heritrix allow for the user to make a distinction between hotlinked content on other hosts vs hyperlinks to other hosts) but I'd like to see if this is possible with wget. Ideally this would not be done in post-processing, as I would like the external content, requests, and headers to be included in the WARC file I'm outputting.

• C#/DataSet: Create and bind a custom column/property in a DataSet`s DataTable in the XXXDataSet.cs

  - by msfanboy

  Hello, I have a DataSet with a DataTable having the columns Number and Description. I do not want to bind both properties to a BindingSource bound again to 2 controls. What I want is a 3rd column in the DataTable called NumberDescription which is a composition of Number and Description. This property is bound only to 1 control/BindingSource`s property not 2. There is the partial XXXDataSet.Designer.cs file and the partial XXXDataSet.cs file. Of course I have defined the public string NumberDescription {get (doing some checks here;set (doing also some checks here} in the XXXDataSet.cs file. But all this does not bind my new property/Column to the BindingSource the DataTable is bound to because the DataSet does not know the new column/property. To make this new property/column known I could add a new column to the DataTAble in the DataSet designer view naming it NumberDescription. At least I see know the new property in the listing of the BindingSource so I can choose it. But all that did not help?? So how do I do that stuff properly? Should I call the NumberDescription Property in the Number AND Description Property ?

• Write transparent HTTP Proxy script in PHP

  - by Leo Izen

  Is there an easy forwarding/transparent php proxy script that I can host on my web server? These are my conditions: I'm using free web hosting, so I have pretty much no control over my machine. Otherwise I could use Perl's HTTP::Proxy module. This means no root password. It does run php though. I already have a server running on port 80. What I mean is I would like to put a php script as index.php on my server that will forward all requests. I don't want a script like PHProxy or Glype where I go to the site, then enter a URL. I want a server so I can enter proxy.example.com:80 in Firefox's or IE's or whatever's proxy settings and it will forward all requests to the server. Preferably (though not fatal if not possible) I would like for it to pass on the USER_AGENT environmental variable (That's the browser) instead of setting itself to be the USER_AGENT I can't start a new Daemon. My server won't allow it. Is there a script that will do this? If so, which?

• How do I call C++/CLI (.NET) DLLs from standard, unmanaged non-.NET applications?

  - by tronjohnson

  In the unmanaged world, I was able to write a __declspec(dllexport) or, alternatively, use a .DEF file to expose a function to be able to call a DLL. (Because of name mangling in C++ for the __stdcall, I put aliases into the .DEF file so certain applications could re-use certain exported DLL functions.) Now, I am interested in being able to expose a single entry-point function from a .NET assembly, in unmanaged-fashion, but have it enter into .NET-style functions within the DLL. Is this possible, in a simple and straight-forward fashion? What I have is a third-party program that I have extended through DLLs (plugins) that implement some complex mathematics. However, the third-party program has no means for me to visualize the calculations. I want to somehow take these pre-written math functions, compile them into a separate DLL (but using C++/CLI in .NET), but then add hooks to the functions so I can render what's going on under the hood in a .NET user control. I'm not sure how to blend the .NET stuff with the unmanaged stuff, or what to Google to accomplish this task. Specific suggestions with regard to the managed/unmanaged bridge, or alternative methods to accomplish the rendering in the manner I have described would be helpful. Thank you.

• How can I [simply] consume JSON Data in a Line of Business Web Application

  I usually use JSON with jQuery to just return a string with html. However, I want to start to use Javascript objects in my code. What's the simplest way to get started using json objects on my page? Here's a sample Ajax call ( after $(document).ready( { ... }) of course: $('#btn').click(function(event) { event.preventDefault(); var out = $('#result'); $.ajax({ url: "CustomerServices.asmx/GetCustomersByInvoiceCount", success: function(msg) { // // Iterate through the json results and spit them out to a page? // }, data: "{ 'invoiceCount' : 100 }" }); }); My WebMethod: [WebMethod(Description="Gets customers with more than n invoices")] public List<Customer> GetCustomersByInvoiceCount(int? invoiceCount) { using (dbDataContext db = new dbDataContext()) { return db.Customers.Where(c => c.InvoiceCount >= invoiceCount); } } What gets returned: {"d":[{"__type":"Customer","Account":"1116317","Name":"SOME COMPANY","Address":"UNit 1 , 392 JOHN ST.

","LastTransaction":"\/Date(1265097600000)\/","HighestBalance":549.42}]} What I'd LIKE to know, is what are people generally doing with this returned json? Do you iterate through the properties and create an html table on the fly? Is there way to "bind" JSON data using a javascript version of reflection ( something like the .Net GridView Control ) Do you throw this returned data into a Javascript Object and then do something with it? An example of what I want to achieve is to have an plain ol' html page ( on a mobile device )with a list of a Salesperson's Customers. When one of those customers are clicked, the customer id gets sent to a webservice which retrieves the customer details that are relevant to a sales person. I know the SO talent pool is quite deep so I figured you all here would be able to guide in the right direction and give me a few ideas on the best way to approach this.

• Response Redirect - Open Link in New Window

  - by bacis09

  First, I've taken the time to review this question which seems to be the most similar, however, the solution that seems to have been selected will not work in my scenario.Not to mention I worry about some of the comments claiming it to be brittle or an inadequate solution. http://stackoverflow.com/questions/104601/asp-net-response-redirect-to-new-window -We have an XML document which basically contains all of the information for a Side menu. -We have numerous URLS which are stored in a constants class. -One of the elements in a string of XML (well call it label) is used to determine if the menu item is created as a LinkButton or a Label. -Links use a custom user control that is used standard for all links across the application (why suggestion on similar thread doesn't work - I don't want all links to open in a new window - just one) -One of the elements in a string of XML (well call it function) is used in a Switch statement to generate our links using Response Redirect. It may look something like this. switch (function) { case goto 1: string url; if (user_group == 1) { url = Constants.CONSTANT1 } else { url = Constants.CONSTANT2 } Response.Redirect(url) case goto 2: ...... default: ...... break; } Given this scenario, I'm trying to find the best way to quickly open a New Window, when a specific case in this switch statement is met. Can it be done with Response Redirect (this seems to be arguable - people say no it can't, yet other people say they have made it work)? If not, what alternative can work here?

• How to create two columns on a web page?

  - by Roman

  I want to have two columns on my web page. For me the simples way to do that is to use a table: <table> <tr> <td> Content of the first column. </td> <td> Content of the second column. </td> </tr> </table> I like this solution because, first of all, it works (it gives exactly what I want), it is also really simple and stable (I will always have two columns, no matter how big is my window). It is easy to control the size and position of the table. However, I know that people do not like the table-layout and, as far as I know, they use div and css instead. So, I would like also to try this approach. Can anybody help me with that? I would like to have a simple solution (without tricks) that is easy to remember. It also needs to be stable (so that it will not accidentally happen that one column is under another one or they overlap or something like that).

• Flex 4: Scale to a point (zoom into an image where the mouse was clicked)

  - by Jason W

  I've been trying to get this working and I can't seem to figure it out. There is an Image control that when I click on it I need to zoom in (using the center/transform point where the mouse is clicked). I have the zoom transition working great, but when I set transformX & tranformY (with autoCenterTransform false) it doesn't zoom into that point. Here is my code that only zooms in (not to a specific point) <fx:Script> <![CDATA[ protected function imgLogo_clickHandler(event:MouseEvent):void { transformer.play(); } ]]> </fx:Script> <fx:Declarations> <s:Parallel id="transformer" target="{imgLogo}"> <s:Scale scaleXBy="0.5" scaleYBy="0.5" /> </s:Parallel> </fx:Declarations> <mx:Image id="imgLogo" width="250" x="100" y="100" maintainAspectRatio="true" source="@Embed('src/logo.png')" click="imgLogo_clickHandler(event)" /> Any help is greatly appreciated. Thanks
