• ASP.NET Setting Culture with InitializeCulture

  - by Helen

  I have a website with three domains .com, .de and .it Each domain needs to default to the local language/culture of the country. I have created a base page and added an InitializeCulture Protected Overrides Sub InitializeCulture() Dim url As System.Uri = Request.Url Dim hostname As String = url.Host.ToString() Dim SelectedLanguage As String If HttpContext.Current.Profile("PreferredCulture").ToString Is Nothing Then Select Case hostname Case "www.domain.de" SelectedLanguage = "de" Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage) Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage) Case "www.domain.it" SelectedLanguage = "it" Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage) Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage) Case Else SelectedLanguage = "en" Thread.CurrentThread.CurrentUICulture = New CultureInfo(SelectedLanguage) Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(SelectedLanguage) End Select End If End Sub This is fine. The problem now occurs because we also want three language selection buttons on the home page so that the user can override the domain language. So on my Default.asp.vb we have three button events like this... Protected Sub langEnglish_Click(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs) Handles langEnglish.Click Dim SelectedLanguage As String = "en" 'Save selected user language in profile HttpContext.Current.Profile.SetPropertyValue("PreferredCulture", SelectedLanguage) 'Force re-initialization of the page to fire InitializeCulture() Context.Server.Transfer(Context.Request.Path) End Sub But of course the InititalizeCulture then overrides whatever button selection has been made. Is there any way that the InitialCulture can check whether a button click has occurred and if so skip the routine? Any advice would be greatly appreciated, thanks.

• How to Add, Edit and Display one to many relationship entities in ASP.Net MVC 2?

  - by Picflight

  I am looking for best practices conforming to the MVC design pattern. My Entities have the following relationship. tblPortal PortalId PrortalName tblPortalAlias AliasId PortalId HttpAlias Each Portal can have many PortalAlias. I want to Add a New Portal and then Add the associated PortalAlias. I am confused on how I should structure the Views and how I should present the Views to the user. I am looking for some sample code on how to accomplish this. My thoughts are first present the Portal View, let the user add the Portal. Then click the Edit link on the Portal List View and on the Portal Edit View let them Add the PortalAlias. If so, what should the Edit View look like? So far I have: Edit <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<MyProject.Mvc.Models.PortalFormViewModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Edit </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Edit</h2> <% Html.RenderPartial("PortalForm", Model); %> <div> <%= Html.ActionLink("Back to List", "Index") %> </div> </asp:Content> PortalForm <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<MyProject.Mvc.Models.PortalFormViewModel>" %> <%= Html.ValidationSummary("Please correct the errors and try again.") %> <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.Portal.PortalId) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Portal.PortalId) %> <%= Html.ValidationMessageFor(model => model.Portal.PortalId) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Portal.PortalName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Portal.PortalName) %> <%= Html.ValidationMessageFor(model => model.Portal.PortalName) %> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> Alias<br /><%-- This display is for debug --%> <% foreach (var item in Model.PortalAlias) { %> <%= item.HTTPAlias %><br /> <% } %> PortalFormViewModel public class PortalFormViewModel { public Portal Portal { get; private set; } public IEnumerable<PortalAlias> PortalAlias { get; private set; } public PortalFormViewModel() { Portal = new Portal(); } public PortalFormViewModel(Portal portal) { Portal = portal; PortalAlias = portal.PortalAlias; } }

• Error in Visual Studio 2008 with SSRS 2005 report projects

  - by Tj Kellie

  Has anyone found a good workaound for opening or editing an SSRS 2005 report project with Visual Studio 2008 yet? Will the SQL server 2008 tools be the migration path for these report projects in the future? I really dont want to have to keep VS2005 installed forever just to update SSRS reports. After an upgrade to VS2008 an existing solution that contains a VS2005 SSRS reports project will not open. From what I understand the SQL Server 2005 tools dont know about VS2008 so they will not integrate into the IDE. So currently I switch back to VS2005 for any updates to this project, and get an error loading project message everytime I open the solution in 2008. EDIT on solution: I was able to install the shared component for BDIS from the SQL2008 disc and am now able to open and update my SSRS 2005 .rdl project items within VS2008. Note to others: If you edit your SSRS 2005 reports in VS2008 and re-save you will not be able to edit them in VS2005 anymore, or deploy them to a 2005 server. They are up-converted to 2008 report files.

• Debugging Cactus Tests in Eclipse

  - by Th3sandm4n

  Side note: This is inherited code, I didn't do any of the setup and am new to the project. I'm trying to set up remote debugging in Eclipse for these unit tests that use Cactus. I've read around a bit (but I can't seem to find any REAL information how to set this up). Closest I've found is here (http://www.eclipse.org/webtools/community/tutorials/CactusInWTP/CactusInWTP.html), but it just says to Debug - Debug on Server, but nowhere does it say where the debug port is set or anything, and I can't find anything on how to enable this, set it. Just asking to see if anyone has set this up before, it would really help stepping through the code rather than just logging. The plugin (http://jakarta.apache.org/cactus/integration/eclipse/runner_plugin.html) Looks promising, but I also don't even know where to download it, it doesn't link to a location -.- The project uses ant, cactus, and I'm using Eclipse. Thanks EDIT Here is the target I'm using <junit fork="no" forkmode="perTest" printsummary="yes" haltonfailure="no" haltonerror="no" failureproperty="tests.failed"> <jvmarg value="-Xdebug" /> <jvmarg value="-Xrunjdwp:transport=dt_socket,address=localhost:8005,server=y,suspend=y" /> <formatter type="xml" usefile="true" /> <formatter type="plain" usefile="false" /> <classpath> <pathelement location="${clover.jar}"/> <path refid="cactus.classpath.id" /> <pathelement location="../ejb/src" /> </classpath> <sysproperty key="cactus.contextURL" value="${cactus.contextURL}"/> <test name="com.test.AllTests" outfile="TESTS" /> </junit>

• IIS 6 with wildcard mapping and UNC virtual directory problem

  - by El Che

  Hi. On our production servers (win 2003 with IIS6 and load balanced with an F5 BIGIP), we have a problem when introducing wildcardmapping on IIS6. We use .net Framework 3.5 SP1. The issue manifests itself as by the server only sometimes serving the images stored on a virtual directory pointing to a UNC path. Sometimes the images are displayed, and sometimes not. Removing the wildcard mapping solved this problem. I will need wildcard mapping on the server for future features, so any help/pointers to if this is a known problem will be very helpful. In advance, thanks for any help. Edit: The exception it fails with is the following: Message: Failed to start monitoring changes to '\ourFileServer\folder1\thumbnails' because the network BIOS command limit has been reached. For more information on this error, please refer to Microsoft knowledge base article 810886. Hosting on a UNC share is not supported for the Windows XP Platform.

• Sending data through POST request from a node.js server to a node.js server

  - by Masiar

  I'm trying to send data through a POST request from a node.js server to another node.js server. What I do in the "client" node.js is the following: var options = { host: 'my.url', port: 80, path: '/login', method: 'POST' }; var req = http.request(options, function(res){ console.log('status: ' + res.statusCode); console.log('headers: ' + JSON.stringify(res.headers)); res.setEncoding('utf8'); res.on('data', function(chunk){ console.log("body: " + chunk); }); }); req.on('error', function(e) { console.log('problem with request: ' + e.message); }); // write data to request body req.write('data\n'); req.write('data\n'); req.end(); This chunk is taken more or less from the node.js website so it should be correct. The only thing I don't see is how to include username and password in the options variable to actually login. This is how I deal with the data in the server node.js (I use express): app.post('/login', function(req, res){ var user = {}; user.username = req.body.username; user.password = req.body.password; ... }); How can I add those username and password fields to the options variable to have it logged in? Thanks

• PInvoke Unbalances the stack

  - by Giawa

  Good afternoon, I have been working on a dll that can use CORBA to communicate to an application that is network aware. The code works fine if I run it as a C++ console application. However, I have gotten stuck on exporting the methods as a dll. The methods seems to export fine, and if I call a method with no parameters then it works as expected. I'm hung up on passing a C# string to a C++ method. My C++ method header looks like this: bool __declspec(dllexport) SpiceStart(char* installPath) My C# DLL import code is as follows: [DllImportAttribute("SchemSipc.dll", CharSet=CharSet.Ansi)] private static extern bool SpiceStart(string installPath); I call the method like so: bool success = SpiceStart(@"c:\sedatools"); The call to SpiceStart throws the exception "PInvokeStackImbalance", which "is likely because the managed PInvoke signature does not match the unmanaged target signature." Does anyone have any suggestions? If I remove the char* and string from the parameters, then the method runs just fine. However, I'd like to be able to pass the installation path of the application to the dll from C#. Thanks in advance, Giawa

• Entity Framework: insert with one-to-one reference

  - by bomortensen

  Hi 'overflow! I'm having a bit trouble inserting into a mssql database using Entity Framework. There's two tables that I want to insert into, where one of table 1s fields is a foreign key in table2. This is the code I have so far: Media media = null; foreach(POI p in poiList) { media = new Media() { Path = p.ImagePath, Title = p.Title }; if (media != null && !context.Media.Any(me => me.Title == p.ImageTitle)) { context.AddToMedia(media); context.SaveChanges(); } PointOfInterest poi = new PointOfInterest() { Altitude = 2000.0, ID = p.ID, Latitude = p.Latitude, Longitude = p.Longitude, LatitudeRoute = p.LatitudeRoute, LongitudeRoute = p.LongitudeRoute, Description = p.Description, Title = p.Title, DefaultImageID = media.ID, }; context.AddToPointOfInterest(poi); } context.SaveChanges(); The following gives me this error: An object with the same key already exists in the ObjectStateManagerAn object with the same key already exists in the ObjectStateManager I'm still learning how to use the entity framework, so I don't even know if this would be the right approach to insert into two referenced tables. Can anyone enlighten me on this? :) Any help would be greatly appreciated! Thanks!

• PHP4 including file during session

  - by Matherw

  I am trying to put second language on my webpage. I decided to use different files for different languages told apart by path - language/pl/projects.ln contains Polish text, language/en/projects.ln - English. Those extensions are just to tell language files from other, the content is simple php: $lang["desc"]["fabrics"]["title"] = "MATERIALY"; $lang["desc"]["fabrics"]["short_text"] = "Jakis tam tekst na temat materialów"; $lang["desc"]["services"]["title"] = "USLUGI"; $lang["desc"]["services"]["short_text"] = "Jakis tam tekst na temat uslóg"; And then on the index page I use it like so: session_start(); if (isset($_SESSION["lang"])) { $language = $_SESSION["lang"]; } else { $language = "pl"; } include_once("language/$language/projects.ln"); print $lang["desc"]["fabrics"]["title"]; The problem is that if the session variable is not set everything works fine and array item content is displayed but once I change and set $_SESSION["lang"] nothing is displayed. I tested if the include itself works as it should by putting print "sth"; at the beginning of projects.ln file and that works all right both with $_SESSION["lang"] set and unset. Please help.

• Enable DOM Access for Silverlight Web Part in Sharepoint 2010

  - by Bhaskar

  I am hosting a silverlight 3.0 control on my Sharepoint 2010 page. I am using the built-in SilverlightWebPart web part, where I have provided the path for .xap file. Its displaying properly, but when I try to access the System.Windows.Browser, its throwing an error. My code is: public static string GetQueryString(string key) { try { var documentQueryString = (Dictionary<string, string>)System.Windows.Browser.HtmlPage.Document.QueryString; if (documentQueryString.ContainsKey(key)) { return documentQueryString[key].ToString(); } } catch (Exception ex) { return ex.Message; } return string.Empty; } The error I am getting is: The DOM/scripting bridge is disabled. How do I enable this? I know if I host this in a ASP.NET page, I can add the param - <param name="enablehtmlaccess" value="true"/>. I have tried putting this webpart in a "content editor web part", and I have embedded the object tag to call the .xap file and its working totally fine. I need to make it work using the built-in Silverlight web part.

• Merge Word Documents (Office Interop & .NET), Keeping Formatting

  - by mbmccormick

  I'm having some difficulty merging multiple word documents together using Microsoft Office Interop Assemblies (Office 2007) and ASP.NET 3.5. I'm able to merge the documents, but some of my formatting is missing (namely the fonts and images). My current merge code is shown below. private void CombineDocuments() { object wdPageBreak = 7; object wdStory = 6; object oMissing = System.Reflection.Missing.Value; object oFalse = false; object oTrue = true; string fileDirectory = @"C:\documents\"; Microsoft.Office.Interop.Word.Application WordApp = new Microsoft.Office.Interop.Word.Application(); Microsoft.Office.Interop.Word.Document wDoc = WordApp.Documents.Add(ref oMissing, ref oMissing, ref oMissing, ref oMissing); string[] wordFiles = Directory.GetFiles(fileDirectory, "*.doc"); for (int i = 0; i < wordFiles.Length; i++) { string file = wordFiles[i]; wDoc.Application.Selection.Range.InsertFile(file, ref oMissing, ref oMissing, ref oMissing, ref oFalse); wDoc.Application.Selection.Range.InsertBreak(ref wdPageBreak); wDoc.Application.Selection.EndKey(ref wdStory, ref oMissing); } string combineDocName = Path.Combine(fileDirectory, "Merged Document.doc"); if (File.Exists(combineDocName)) File.Delete(combineDocName); object combineDocNameObj = combineDocName; wDoc.SaveAs(ref combineDocNameObj, ref m_WordDocumentType, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing, ref oMissing); } I don't care necessarily how this is accomplished. It could output via PDF if it had to. I just want the formatting to carry over. Any help or hints that you could provide me with would be appreciated! Thanks!

• Extracting a specific value from command-line output using powershell

  - by Andrew Shepherd

  I've just started learning PowerShell this morning, and I'm grappling with the basics. Here's the problem: I want to query subversion for the revision number of a repository, and then create a new directory with this revision number. The command svn_info outputs a number of label\value pairs, delimited by colons. For example Path: c# URL: file:///%5Copdy-doo/Archive%20(H)/Development/CodeRepositories/datmedia/Development/c%23 Repository UUID: b1d03fca-1949-a747-a1a0-046c2429f46a Revision: 58 Last Changed Rev: 58 Last Changed Date: 2011-01-12 11:36:12 +1000 (Wed, 12 Jan 2011) Here is my current code which solves the problem. Is there a way to do this with less code? I'm thinking that with the use of piping you could do this with one or two lines. I certainly shouldn't have to use a temporary file. $RepositoryRoot = "file:///%5Cdat-ftp/Archive%20(H)/Development/CodeRepositories/datmedia" $BuildBase="/Development/c%23" $RepositoryPath=$RepositoryRoot + $BuildBase # Outputing the info into a file svn info $RepositoryPath | Out-File -FilePath svn_info.txt $regex = [regex] '^Revision: (\d{1,4})' foreach($info_line in get-content "svn_info.txt") { $match = $regex.Match($info_line); if($match.Success) { $revisionNumber = $match.Groups[1]; break; } } "Revision number = " + $revisionNumber;

When I run python manage.py shell on the command line, it works fine: >python manage.py shell Python 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. (InteractiveConsole) >>> from mysite.myapp.models import School >>> School.objects.all() [] Works great. Then, I try to do the same thing in Eclipse (using a Django project that is composed of the same files.) Right click on mysite project Django Shell with Django environment This is the output from the PyDev Console: >>> import sys; print('%s %s' % (sys.executable or sys.platform, sys.version)) C:\Python26\python.exe 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] >>> >>> from django.core import management;import mysite.settings as settings;management.setup_environ(settings) 'path\\to\\mysite' >>> from mysite.myapp.models import School >>> School.objects.all() Traceback (most recent call last): File "<console>", line 1, in <module> File "C:\Python26\lib\site-packages\django\db\models\query.py", line 68, in __repr__ data = list(self[:REPR_OUTPUT_SIZE + 1]) File "C:\Python26\lib\site-packages\django\db\models\query.py", line 83, in __len__ self._result_cache.extend(list(self._iter)) File "C:\Python26\lib\site-packages\django\db\models\query.py", line 238, in iterator for row in self.query.results_iter(): File "C:\Python26\lib\site-packages\django\db\models\sql\query.py", line 287, in results_iter for rows in self.execute_sql(MULTI): File "C:\Python26\lib\site-packages\django\db\models\sql\query.py", line 2368, in execute_sql cursor = self.connection.cursor() File "C:\Python26\lib\site-packages\django\db\backends\__init__.py", line 81, in cursor cursor = self._cursor() File "C:\Python26\lib\site-packages\django\db\backends\sqlite3\base.py", line 170, in _cursor self.connection = Database.connect(**kwargs) OperationalError: unable to open database file What am I doing wrong here?

• GTK#-related error on MonoDevelop 2.8.5 on Ubuntu 11.04

However, I've installed (and re-installed) anything GTK#-related that I could think of... and the error still occurs. Does anyone know how to fix it?

• Sphinx PHP search

  - by James

  I'm doing a Sphinx search but turning up some really weird results. Any help is appreciated. So for example if I type "50", I get: 50 Cent 50 Lions 50 Foot Wave, etc. This is great, but when I search "50 Ce", I get: Ryczace Dwudziestki Spisek Bernhard Gal Cowabunga Go-Go And other crazy results. Also when I search for "50 Cent", the correct result is at the top, but then random results below. Any ideas why? PHP code: $query = $_GET['query']; if (!empty($query)) { $sphinx->SetMatchMode(SPH_MATCH_ALL); $sphinx->AddQuery($query, 'artists'); $sphinx->AddQuery($query, 'variations'); $sphinx->SetFilter('name', array(3)); $sphinx->SetLimits(0, 10); $result = $sphinx->RunQueries(); echo '<pre>'; switch ($result) { case false: echo 'Query failed: ' . $sphinx->GetLastError() . "\n"; break; default: if ($sphinx->GetLastWarning()) { echo 'WARNING: ' . $sphinx->GetLastWarning() . "\n"; } if (is_array($result[0]['matches']) && count($result[0]['matches'])) { foreach ($result[0]['matches'] as $value => $info) { $artist = artistDetails($value); echo $artist['name'] . "\n"; } } } } Sphinx Index and Source: source artists { type = mysql sql_host = localhost sql_user = user sql_pass = pass sql_db = db sql_port = 3300 sql_query = \ SELECT \ id, name \ FROM artists; #UNIX_TIMESTAMP(time) #sql_attr_uint = group_id #sql_attr_timestamp = time sql_query_info = SELECT id,name FROM artists WHERE id=$id } index artists { source = artists path = /var/sphinx/artists docinfo = extern charset_type = utf-8 }

• SMO restore of SQL database doesn't overwrite

  - by Tom H.

  I'm trying to restore a database from a backup file using SMO. If the database does not already exist then it works fine. However, if the database already exists then I get no errors, but the database is not overwritten. The "restore" process still takes just as long, so it looks like it's working and doing a restore, but in the end the database has not changed. I'm doing this in Powershell using SMO. The code is a bit long, but I've included it below. You'll notice that I do set $restore.ReplaceDatabase = $true. Also, I use a try-catch block and report on any errors (I hope), but none are returned. Any obvious mistakes? Is it possible that I'm not reporting some error and it's being hidden from me? Thanks for any help or advice that you can give! function Invoke-SqlRestore { param( [string]$backup_file_name, [string]$server_name, [string]$database_name, [switch]$norecovery=$false ) # Get a new connection to the server [Microsoft.SqlServer.Management.Smo.Server]$server = New-SMOconnection -server_name $server_name Write-Host "Starting restore to $database_name on $server_name."

• C# Assembly not found at runtime

  - by Gustavo Cardoso

  A strange error begans to happen with my XNA project on a new pc. I have two projects on the solution and a library that is used by both of them. One of the projects, a XNA Game Project, runs perfectly. The other project is a mix of WindowsForm and XNA. The form launches a XNA class when a button is clicked. When I run the program, it works great till the moment I click the button which launch the XNA class. A FileNotFoundException is fired exactly at the moment that the constructor will be executed. System.IO.FileNotFoundException was unhandled Message="Could not load file or assembly 'Microsoft.Xna.Framework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=6d5c3888ef60e27d' or one of its dependencies. The system cannot find the path specified." The reference is correct, there is no problem on compilation. We already tried to delete the reference and add it again but it didn't work. Everything worked correctly in others teammate's pc. Anyone has any idea what is the problem?
