• Why doesn't BlackBerry let me click on this link?

  - by Steve N

  This is a link in an HTML email.. Other links in this email work, but this one does not get recognized in a BlackBerry as a link, so you can't click on it. Does anyone know why that might be? Here's the markup for it: <a title="Continue" style="display: block; width:200px; border:1px solid #336699; text-align: center; padding-top:5px; padding-bottom:5px; font-size:14px; font-family: Arial, Sans-Serif; color:#336699; font-weight:bold; text-decoration: none;" href="https://www.mydomain.com/mypage.aspx?id=8430650">Continue ››</a>

• Response.Redirect exception

  - by Tedd Hansen

  Executing the line: Response.Redirect("Whateva.aspx", true); Results in: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code The exception is because of the "true" part, telling it to end the current request immediately. Is this how it should be? If we consider: Exceptions are generally considered heavy, and many times the reason for ending the request early is to avoid processing the rest of the page. Exceptions show up in performance monitoring, so monitoring the solution will show a false number of exceptions. Is there an alternative way to achieve the same?

• JQuery pass model to controller

  - by slandau

  I want to pass the mvc page model back to my controller within a Javascript Object. How would I do that? var urlString = "<%= System.Web.VirtualPathUtility.ToAbsolute("~/mvc/Indications.cfc/ExportToExcel")%>"; var jsonNickname = { model: Model, viewName: "<%= VirtualPathUtility.ToAbsolute("~/Views/Indications/TermSheetViews/Swap/CashFlows.aspx")%>", fileName: 'Cashflows.xls' } $.ajax({ type: "POST", url: urlString, data: jsonNickname, async: false, success: function (data) { $('#termSheetPrinted').append(data); } }); So where it says model: Model, I want the Model to be the actual page model that I declare at the top of the page: Inherits="System.Web.Mvc.ViewPage<Chatham.Web.Models.Indications.SwapModel>" How can I do that?

• Problem with passing folder path string to web service function via jQuery.ajax

  - by the_V

  Hello, I need to perform asp.net web-service function call via jQuery and pass asp.net application path to it. That's the way I'm trying to do it (code is located within asp.net page, e.g. aspx file): var d = "{'str':'<%=System.DateTime.Now.ToString() %>', 'applicationPath':'<%=GetApplicationPath() %>'}"; $.ajax({ type: "POST", url: "http://localhost/testwebsite/TestWebService.asmx/Test", data: d, contentType: "application/json; charset=utf-8", dataType: "json", error: function (xhr, status, error) { var err = eval("(" + xhr.responseText + ")"); alert(err.Message); }, success: function (msg) { } }); That's what GetApplicationPath method looks like: protected string GetApplicationPath() { return HttpUtility.HtmlEncode(Request.PhysicalApplicationPath); } And here is a header of web-service function which I'm trying to call: public void Test(string str, string applicationPath) Function call works well, but applicationPath parameter doesn't passed correctly. When I debug it I see that backslashes are removed, function gets "C:ProjectsSamplesmytestwebsite" instead of "'C:\Projects\Samples\mytestwebsite\'". How can I overcome this?

• Hit external url from code-behind

  - by Steven

  I have a form on my site. The user enters their e-mail and selects a location from a dropdown. I then need to post that data to an external site by hitting a url with the user's location and e-mail in the query string. I'm doing this like so: string url = "http://www.site.com/page.aspx?location=" + location.Text + "&email=" + email.Text; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); My client says that I am not hitting their server, but when going through the debugger, I'm getting a response from their server. I also tried tracking what was happening by using Firebug, and I noticed that there was no POST made to that external site. What am I doing wrong here?

• C# connectionString encryption questions

  - by 5YrsLaterDBA

  I am learning how to encrypt the ConnectionString for our C# (3.5) Application. I read the .Net Framwork Developer Guide (http://msdn.microsoft.com/en-us/library/89211k9b(VS.80).aspx) about securing connection string. but not fully understand the contents. It says "The connection string can only be decrypted on the computer on which it was encrypted." We have a release machine which will build our application which will generate the OurApp.exe.config and then install it to many product machines. Is that meam we have to have this encryption process separated with our application and run it at individual product machine? We may use the "RSAProtectedConfigurationProvider". It mentioned we need encryption key for that provider. when and how we should provide the encryption key? thanks,

• Mapping to a different view based on child type

  - by Ryan Burnham

  So i have a situation where i have common base type but i need to map to a different view based on the child type. It looks like i can use a generic mapping class to handle the inheritance http://geekswithblogs.net/nharrison/archive/2010/07/09/inheriting-a-class-map-in-fluent-nhibernate.aspx But how can i conditionally map to a different view based on the child type? I see an EntityType property but it says its obsolete and will be made private in the next version. As an example i have a base class of ContactInfo is standard between contact types but the values come from different places depending on the contact type, this I'll handle through the sql view.

• Why I should use an N-Tier Approach When using an SqlDatasource is ALOT EASIER ?

  - by The_AlienCoder

  When it comes to web development I have always tried to work SMART not HARD. So for along time My Aproach to interacting with databases in my AspNet projects has been this : 1) Create my stored procedures 2) Drag an SQLDatasource control on my aspx page 3) Bind a DataList Control to my SQLDatasource 4) Insert, Update & Delete by using my Datalist or programmatically using built in SQLDatasource methods e.g MySqlDataSource.InsertParameters["author"].DefaultValue = TextBox1.Text; MySqlDataSource.Insert(); Recently however I got a relatively easy web project. So I decided to employ a 3-tier Model...But I got exhausted halfway and just didnt seem worth it ! It seemed like I was working too HARD for a project that could have been easily accomplished by a couple of SqlDataSource Controls. So Why Is the N-Tier Model better than my Approach? Has it anything to do with performance? What are the advantages of the ObjectDataSource control over the SqlDataSource Control?

• Why operator= returns reference not const reference

  - by outmind

  The original question is related to overloading operator= and I like to share my findings as it was nontrivial for me to find them. I cannot imagine reasonable example to use (a=b) as lvalue. With the help of IRC and google I've found the next article: http://msdn.microsoft.com/en-us/magazine/cc301415.aspx it provides two examples. (a=b)=c f(T& ); f(a=b) but both a bit not good, as first violate associativity and I believe that it is bad practice. The second one give me the same feeling. Could you provide more good examples why it should be non constant?

• Do validations still fire in ASP.NET even if the controls are hidden?

  - by Josh

  I have a form that uses ASP.NET validations. I am using some inline C# in the aspx to show/hide certain controls depending on a user's role. I would use the Visible property, but there are so many of them, I just decided to do inline C# to show and hide (I know, not best practice, but bear with me for a second). I am having an issue where Page.IsValid is always set to False when I submit my form (when certain fields are being hidden). Will the validations still fire off even if the controls are not even rendered on the pag? Also, if this is not the case, is there an effective way of breaking down Page.IsValid to find out what is setting it to False? Thanks.

• How can I make this run on all my files automatically? YUI Compressor for Visual Studios

  - by chobo2

  Hi So I found this page http://blog.lavablast.com/post/2009/05/YUI-Compressor-for-Visual-Studio.aspx and how to put YUI compressor into Visual studios(I am using visual studios 2010 express). So it got me thinking can I somehow set it in my project to always take my "development scripts" and minify them automatically. Right now if I make a change to my script I have to remember to minify it once I am done otherwise I could be using a out to day version. So it would be cool if I could just set up like so when I build it takes all my development scripts and then minifys them. How could I do something like this?

• Securing Web Services approach valid?

  - by NBrowne

  Hi , Currently I am looking at securing our web services. At the moment we are not using WCF so this is not an option. One approach I have seen and implemented locally fairly easily was the approach described in article: http://www.codeproject.com/KB/aspnet/wsFormsAuthentication.aspx Which describes adding a HttpModule which prompts for user credentials if the user browses to any pages (web services) which are contained in a services folder. Does anyone see any way that this security could fall down and could be bypassed etc. I'm really just trying to decide whether this is a valid approach to take or not? thanks

• SQL Server Reporting Services using of pictures with dynamic links

  - by YvesR

  I have setup a SSRS 2008 and building reports. So far so good. Now there is a picture control in SSRS where you can set the picture as external link reference. There you can choose to use a link. When I use a weblink (http://anyurl/download_picture.aspx?id=123) it dont' work for me. Calling the url in the web browser (all tested IE, Safari, Chrome, FF) the pictures is delivered, Header is ok, content type, too. Does it work in general in SSRS ? Or do I have to copy the picture to a temp folder and link the url like http://anyurl/mypicture.jpg.

• Too many local variables in ASP.NET

  - by Yongwei Xing

  Hi all I wrote a control, and use a tool to do the code analysis. There is a test that I didn't pass. Avoid excessive locals, http://msdn.microsoft.com/library/ms182263(VS.90).aspx. In my CreateChildControls function, I built a big table with lots of field. I need to create a lot of TableRow and TableCell to construct the table. But these are not field or property of control. Thery are local variables in the function, which are created dynamically. Should I make these TableCells and TableRows as fields of the control? Or I just keep them as the local variables in the CreateChildControl function? Best Regards,

• SubSonic Change DropDown Value for Load Drops SUB

  - by GTJR

  I used the subsonic generator to create some aspx pages, It works fine. On some of the pages it automaticaly generated the dropdown boxes for foreign key values. How Can change that value in the load drops code? Or where I need to change it. For instance I have a workers table and a workersweek table. The workers table has a workerid,firstname and lastname field and the workersweek has a workerID field. The generator automatically set it up to show the firstname in the dropdown. I want to change the value to be both firstname and lastname. I am sure I will have to add code that does something like firstname + " " + Lastname. I am just not sure where to do it withing the code that was generated. I see the load drops sub, but it does not seem like that is the one I need to modify.

• Is MSDN referencing a system.thread, a worker thread, an io thread or all three?

  - by w0051977

  Please see the warning below taken from the StreamWriter class specification (http://msdn.microsoft.com/en-us/library/system.io.streamwriter.aspx): "Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe." I understand that a W3WC process contains two thread pools i.e. worker threads and I/O threads. A worker thread could contain many threads of its own (if the application creates its own System.Thread instances). Does the warning only relate to System.Threads or does it relate to worker threads and I/O threads as well I.e. as the instance variables of the streamwriter class are not thread safe then does this mean that there would be problems if multiple worker threads access it eg if two users on two different web clients attempt to write to the log file at the same time, then could one lock out the other?

• An example of advanced database search

  - by Phil

  Hi there, im looking for an example script. I saw one yesterday but for the life of me I can't find it again today. The task I have is to allow the user to search 1 database table via input controls on an aspx page where they can select and , or , equals to combine fields, generating the sql on the fly with a stringbuilder or similar. (it runs behind the corp firewall) Please can someone point me in the right direction of an example or tutorial I've been working on the page, but have run into problems. Here is a snippet; If NameSearch.Text IsNot String.Empty And andor1v IsNot "0" Then sql += "Surname LIKE '%" & name & "%' " & andor1v & " " ElseIf NameSearch.Text IsNot String.Empty And andor1v Is "0" Then sql += "Surname LIKE '%" & name & "%' " End If

• Change save to file name but from the client

  - by Rhythmic Algorithm

  This question asks about file name the servers sends and the fix was quite simply a content-disposition header in the http response. What I interested in is does anyone know of any way to do this from the client side if the file name is already known? Is there any special javascript to do this for example? A site I have to use but not mine has a FileDownload.aspx but it doesn't send the content-disposition header. I know the filename and would like to be able to create a firefox extensions to use for the poorly coded web site. Thanks

• How to map a virtual directory to a website in VS?

  - by salvationishere

  I am developing a C# VS 2008 website, trying to add a Master file. I created a virtual directory in IIS housing the "Master" folder, containing the Master files. Now how do I reference these files from my website in VS? One problem is I do not know where I need to publish this Master folder to. Other problem is I do not know how to reference this Master file in my aspx Page directive. FYI, this master folder is physically located outside of c:\inetpub\ in a totally separate file location. Is this a problem?
