Multiple Uploadifive in one page is not working

- by jalf

Hello I take my chances here at stack, because uploadify forums is not very responsive and full of spam, I am using uploadifive w/ drag and drop it was amazing but multiple upload buttons in one page is not working. Below is my code: HTML <input type="file" name="file_upload_1" id="file_upload_1"/> <input type="file" name="file_upload_2" id="file_upload_2"/> JS $('#file_upload_1').uploadifive({ 'auto' : true, 'method' : 'post', 'queueID' : 'queue', 'fileType' : ['text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'application/x-csv', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel','application/force-download'], 'uploadScript' : 'upload.php', 'onUploadComplete' : function(file, data) { console.log(data); } }); $('#file_upload_2').uploadifive({ 'auto' : true, 'method' : 'post', 'queueID' : 'queue', 'fileType' : ['text/x-comma-separated-values', 'text/comma-separated-values', 'application/octet-stream', 'application/vnd.ms-excel', 'application/x-csv', 'text/x-csv', 'text/csv', 'application/csv', 'application/excel', 'application/vnd.msexcel','application/force-download'], 'uploadScript' : 'upload.php', 'onUploadComplete' : function(file, data) { console.log(data); } });

.NET SerialPort DataReceived event not firing

- by Klay

I have a WPF test app for evaluating event-based serial port communication (vs. polling the serial port). The problem is that the DataReceived event doesn't seem to be firing at all. I have a very basic WPF form with a TextBox for user input, a TextBlock for output, and a button to write the input to the serial port. Here's the code: public partial class Window1 : Window { SerialPort port; public Window1() { InitializeComponent(); port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); } void port_DataReceived(object sender, SerialDataReceivedEventArgs e) { Debug.Print("receiving!"); string data = port.ReadExisting(); Debug.Print(data); outputText.Text = data; } private void Button_Click(object sender, RoutedEventArgs e) { Debug.Print("sending: " + inputText.Text); port.WriteLine(inputText.Text); } } Now, here are the complicating factors: The laptop I'm working on has no serial ports, so I'm using a piece of software called Virtual Serial Port Emulator to setup a COM2. VSPE has worked admirably in the past, and it's not clear why it would only malfunction with .NET's SerialPort class, but I mention it just in case. When I hit the button on my form to send the data, my Hyperterminal window (connected on COM2) shows that the data is getting through. Yes, I disconnect Hyperterminal when I want to test my form's ability to read the port. I've tried opening the port before wiring up the event. No change. I've read through another post here where someone else is having a similar problem. None of that info has helped me in this case. EDIT: Here's the console version (modified from http://mark.michaelis.net/Blog/TheBasicsOfSystemIOPortsSerialPort.aspx): class Program { static SerialPort port; static void Main(string[] args) { port = new SerialPort("COM2", 9600, Parity.None, 8, StopBits.One); port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); port.Open(); string text; do { text = Console.ReadLine(); port.Write(text + "\r\n"); } while (text.ToLower() != "q"); } public static void port_DataReceived(object sender, SerialDataReceivedEventArgs args) { string text = port.ReadExisting(); Console.WriteLine("received: " + text); } } This should eliminate any concern that it's a Threading issue (I think). This doesn't work either. Again, Hyperterminal reports the data sent through the port, but the console app doesn't seem to fire the DataReceived event. EDIT #2: I realized that I had two separate apps that should both send and receive from the serial port, so I decided to try running them simultaneously... If I type into the console app, the WPF app DataReceived event fires, with the expected threading error (which I know how to deal with). If I type into the WPF app, the console app DataReceived event fires, and it echoes the data. I'm guessing the issue is somewhere in my use of the VSPE software, which is set up to treat one serial port as both input and output. And through some weirdness of the SerialPort class, one instance of a serial port can't be both the sender and receiver. Anyway, I think it's solved.

How do I work around an HTML Table rendering bug in IE 7?

- by osmaniac

I have a table. Some cells span multiple columns. Some cells span multiple rows and columns. But one row (which spans all columns but the rightmost one) creates an artifact. Part of the text in the cell is erroneously repeated left justified on a new row just below the table. I'm baffled. I tried rendering with and without "table-layout: fixed;". Same result. When I originally composed the design using just HTML and CSS, it looked great. But then I worked it into a page and had to add more columns to my master table the right to hold buttons. These buttons are in three groups, each having their own div to control floating and rewrapping when the window gets narrower. One div has another table inside it that groups a single row of buttons. Thus I have table inside div inside td inside outer table. I would prefer a simpler design, but how? This is what I want to have: ................................................................................... . . . . Four rows of data . Three groups of buttons that can reflow . . With several columns . if window gets narrower . . meticulously layed out, . . . That should not resize . . . when window gets narrower . . ................................................................................... . One more row of data spanning the whole screen which stays below the buttons . ................................................................................... What I was doing was putting the three divs with the buttons in the upper right in a single cell that spanned four rows. What other opportunities does CSS offer? The buttons are not allowed to overlap the data on the left or go past the data line below. The original design had the divs with the buttons NOT in a table with the data, but when the window gets narrow, some of the buttons flow such that they go underneath the data, which looks bad. I would post actual HTML, except it is generated by ASP, huge, with lots of CSS styling, and the feature that lets me view the final HTML is not working at the moment. (Built in security in the application.)

c# WebRequest to connect to wikipedia API

Hey, This may be a pathetically simple problem but I cannot seem to format the post webrequest/response to get data from the wikipedia api.

C# WebBrowser Control System.AccessViolationException

- by Aaron Smith

I have a program that uses the built in webbrowser control. At some point during the usage of this, I'm not sure at what point, but it appears to be random, I get the following error: System.AccessViolationException FullText = System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at System.Windows.Forms.UnsafeNativeMethods.DispatchMessageW(MSG& msg) at System.Windows.Forms.Application.ComponentManager.System.Windows.Forms.UnsafeNativeMethods.IMsoComponentManager.FPushMessageLoop(Int32 dwComponentID, Int32 reason, Int32 pvLoopData) at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context) at System.Windows.Forms.Application.Run(Form mainForm) Does anyone have any clues as to why I would get this and how to prevent it?

Read multiple tables from dataset in Powershell

- by Lucas

I am using a function that collects data from a SQL server: function Invoke-SQLCommand { param( [string] $dataSource = "myserver", [string] $dbName = "mydatabase", [string] $sqlCommand = $(throw "Please specify a query.") ) $SqlConnection = New-Object System.Data.SqlClient.SqlConnection $SqlConnection.ConnectionString = "Server=$dataSource;Database=$dbName;Integrated Security=True" $SqlCmd = New-Object System.Data.SqlClient.SqlCommand $SqlCmd.CommandText = $sqlCommand $SqlCmd.Connection = $SqlConnection $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter $SqlAdapter.SelectCommand = $SqlCmd $DataSet = New-Object System.Data.DataSet $SqlAdapter.Fill($DataSet) $SqlConnection.Close() $DataSet.Tables[0] } It works great but returns only one table. I am passing several Select statements, so the dataset contains multiple tables. I replaced $DataSet.Tables[0] with for ($i=0;$i -lt $DataSet.tables.count;$i++){ $Dataset.Tables[$i] } but the console only shows the content of the first table and blank lines for each records of what should be the second table. The only way to see the result is to change the code to $Dataset.Tables[$i] | out-string but I do not want strings, I want to have table objects to work with. When I assign what is returned by the Invoke-SQLCommand to a variable, I can see that I have an array of datarow objects but only from the first table. What happened to the second table? Any help would be greatly appreciated. Thanks

jQuery $.ajax Not Working in IE8 but it works on FireFox & Chrome

- by Sam3k

I have the following ajax call which works perfectly in Firefox and Chrome but not IE: function getAJAXdates( startDate, numberOfNights, opts ) { var month = startDate.getMonth() + 1; var day = startDate.getDate(); var year = startDate.getFullYear(); var d = new Date(); var randNum = Math.floor(Math.random()*100000000); $.ajax({ type : "GET", dataType : "json", url : "/availability/ajax/bookings?rand="+randNum, cache : false, data : 'month='+month+'&day='+day+'&year='+year+'&nights='+numberOfNights, contentType : 'application/json; charset=utf8', success : function(data) { console.log('@data: '+data); insertCellData(data, opts, startDate); }, error:function(xhr, status, errorThrown) { console.log('@Error: '+errorThrown); console.log('@Status: '+status); console.log('@Status Text: '+xhr.statusText); } }); } I know for a fact that all the variables are passing the right content and $.ajax is indeed passing all the paramater/values. This is what I get on error: LOG: @Error: undefined LOG: @Status: parsererror LOG: @Status Text: OK I'm aware of the cache issue on IE and implemented a random paramater to clear it up.

Repository Pattern with Entity Framework 3.5

- by Ravi

I am developing a Database File System. I am using - .Net framework 3.5 Entity Framework 3.5 WPF with MVVM pattern The project spans across multiple assemblies each using same model. One assembly,let's call it a "server", only adds data to the database using EF i.e. same model.Other assemblies (including the UI) both reads and writes the data.The changes made by server should immediately reflect in other assemblies. The database contains self referencing tables where each entity can have single OR no parent and (may be) some children. I want to use repository pattern which can also provide some mechanism to handle this hierarchical nature. I have already done reading on this on Code Project. It shares the same context(entities) everywhere. My question is - Should I share the same context everywhere? What are the advantages and disadvantages of doing that?

How to pass a parameter to jQuery UI dialog event handler?

- by bebraw

I am currently trying to hook up jQuery UI dialog so that I may use it to create new items to my page and to modify ones existing already on the page. I managed in the former. I'm currently struggling in the latter problem, however. I just cannot find a nice way to pass the item to modify to the dialog. Here's some code to illustrate the issue better. Note especially the part marked with XXX. The {{}} parts are derived from Django template syntax: $(".exercise").click(function() { $.post("{{ request.path }}", { action: "create_dialog", exercise_name: $(this).text() }, function(data) { $("#modify_exercise").html(data.content); }, "json" ); $("#modify_exercise").dialog('open'); }); $("#modify_exercise").dialog({ autoOpen: false, resizable: false, modal: true, buttons: { '{% trans 'Modify' %}': function() { var $inputs = $('#modify_exercise :input'); var post_values = {}; $inputs.each(function() { post_values[this.name] = $(this).val(); }); post_values.action = 'validate_form'; //XXX: how to get the exercise name here? post_values.exercise_name = 'foobar'; $.post('{{ request.path }}', post_values, function(data) { if( data.status == 'invalid' ) { $('#modify_exercise').html(data.content); } else { location.reload(); } }, "json" ); } } }); Here's some markup to show how the code relates to the structure: <div id="modify_exercise" class="dialog" title="{% trans 'Modify exercise' %}"> </div> <ul> {% for exercise in exercises %} <li> <a class="exercise" href="#" title="{{ exercise.description }}"> {{ exercise.name }} </a> </li> {% endfor %} </ul>

Initializing links in jqtouch in AJAX loaded content

- by Cody Caughlan

I have an iphone web app built in jqtouch, when content is loaded by links ("a" tags) then any content on the next page is parsed by jqtouch and any links are initialized. However, when I load content via an AJAX call and append() it to an element then any links in that content are NOT initialized by jqtouch. Thus any clicks on those links are full-blown clicks to a new resource and are not handled by jqtouch, so at that point you've effectively broken out of jqtouch. My AJAX code is: #data <script type="text/javascript"> $.ajax({ url: '/mobile/nearby-accounts', type: 'GET', dataType: 'html', data: {lat: lat, lng: lng}, success: function(html) { $('#data').empty().append(html); // Is there some method I call on jqtouch to have any links in $('#data') be hooked up to the jqtouch lifecycle? } </script> Thanks in advance.

How to support both HTTP and HTTPS channels in Flex/BlazeDS?

- by digitalsanctum

I've been trying to find the right configuration for supporting both http/s requests in a Flex app. I've read all the docs and they allude to doing something like the following: <default-channels> <channel ref="my-secure-amf"> <serialization> <log-property-errors>true</log-property-errors> </serialization> </channel> <channel ref="my-amf"> <serialization> <log-property-errors>true</log-property-errors> </serialization> </channel> This works great when hitting the app via https but get intermittent communication failures when hitting the same app via http. Here's an abbreviated services-config.xml: <channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel"> <endpoint url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf" class="flex.messaging.endpoints.AMFEndpoint"/> <properties>  <add-no-cache-headers>false</add-no-cache-headers>  <connect-timeout-seconds>10</connect-timeout-seconds> </properties> </channel-definition> <channel-definition id="my-secure-amf" class="mx.messaging.channels.SecureAMFChannel">  <endpoint url="https://{server.name}:{server.port}/{context.root}/messagebroker/amfsecure" class="flex.messaging.endpoints.AMFEndpoint"/> <properties> <add-no-cache-headers>false</add-no-cache-headers> <connect-timeout-seconds>10</connect-timeout-seconds> </properties> </channel-definition> I'm running with Tomcat 5.5.17 and Java 5. The BlazeDS docs say this is the best practice. Is there a better way? With this config, there seems to be 2-3 retries associated with each channel defined in the default-channels element so it always takes ~20s before the my-amf channel connects via a http request. Is there a way to override the 2-3 retries to say, 1 retry for each channel? Thanks in advance for answers.

I've seen many examples in LINQ but i'm not able to reproduce the same result in vb.net. I have following code: Dim context As New MyModel.Entities() Dim rnd As New System.Random() Dim gardens As List(Of Tuin) = (From t In context.Gardens Where _ t.Approved = True And _ Not t.Famous = True _ Order By rnd.Next() _ Select t).ToList() But i receive an error when binding this list to a control. LINQ to Entities does not recognize the method 'Int32 Next()' method, and this method cannot be translated into a store expression. Any suggestion on how to get this to work?

jQuery attribute selector inside a jQuery object

Im trying to set up a quicksand with multiple filters and the approach im taking in the following which im not sure if its the best. $filteredItems = $containerClone.find('.portfolio-item-marketing').filter(function(index){ if ( $filterA != 'all' && $filterB != 'all' ) { return jQuery(this).find('.portfolio-item-marketing[data-type~=' + $filterA + ']') || jQuery(this).find('.portfolio-item-marketing[data-type~=' + $filterB + ']'); } if ( $filterA != 'all' && $filterB == 'all' ) { return jQuery(this+'[data-type~='+$filterA+']') ; } if ( $filterA == 'all' && $filterB != 'all' ) { return jQuery(this).find('.portfolio-item-marketing[data-type~=' + $filterB + ']'); } if ( $filterA == 'all' && $filterB == 'all' ) { return jQuery(this).find('.portfolio-item-marketing'); } }); As you see in the code i tried 2 different methods ( First "if" and second "if" ). Im not sure if i can use find inside a filter but i also dont know how to get the attribute from the jQuery object. I can not use jQuery(this).attr('data-type') == $filterA Because the attribute maybe contain various filters .Thats why im trying to use jQuery "~=" Should i give up and end using a indexOf ?

INetCfgComponent::RaisePropertyUi arguments

- by Soo Wei Tan

I'm trying to do some COM interop and attempting to invoke the INetCfgComponent::RaisePropertyUi method. I've gotten to the point where I can enumerate devices and get a valid INetCfgComponent for the adapter that I want to display the UI for. However, I'm a COM newbie (let alone COM interop) so I have no idea what the third argument in RaisePropertyUi() is meant to be. I've tried passing in the INetCfgComponent object that I have, but that just results in a InvalidCastException. MSDN has the following to say about the argument: Pointer to the IUnknown interface. RaisePropertyUi retrieves from IUnknown the interface of the context in which to display a network component's property sheet. RaisePropertyUi uses this interface to restrict the display of the property sheet to the context of a connection.

AS 400 Performance from .Net iSeries Provider

- by Nathan

Hey all, First off, I am not an AS 400 guy - at all. So please forgive me for asking any noobish questions here. Basically, I am working on a .Net application that needs to access the AS400 for some real-time data. Although I have the system working, I am getting very different performance results between queries. Typically, when I make the 1st request against a SPROC on the AS400, I am seeing ~ 14 seconds to get the full data set. After that initial call, any subsequent calls usually only take ~ 1 second to return. This performance improvement remains for ~ 20 mins or so before it takes 14 seconds again. The interesting part with this is that, if the stored procedure is executed directly on the iSeries Navigator, it always returns within milliseconds (no change in response time). I wonder if it is a caching / execution plan issue but I can only apply my SQL SERVER logic to the AS400, which is not always a match. Any suggestions on what I can do to recieve a more consistant response time or simply insight as to why the AS400 is acting in this manner when I was using the iSeries Data Provider for .Net? Is there a better access method that I should use? Just in case, here's the code I am using to connect to the AS400 Dim Conn As New IBM.Data.DB2.iSeries.iDB2Connection(ConnectionString) Dim Cmd As New IBM.Data.DB2.iSeries.iDB2Command("SPROC_NAME_HERE", Conn) Cmd.CommandType = CommandType.StoredProcedure Using Conn Conn.Open() Dim Reader = Cmd.ExecuteReader() Using Reader While Reader.Read() 'Do Something End While Reader.Close() End Using Conn.Close() End Using

MP3 Decoding on Android

- by Rob Szumlakowski

Hi. We're implementing a program for Android phones that plays audio streamed from the internet. Here's approximately what we do: Download a custom encrypted format. Decrypt to get chunks of regular MP3 data. Decode MP3 data to raw PCM data in a memory buffer. Pipe the raw PCM data to an AudioTrack Our target devices so far are Droid and Nexus One. Everything works great on Nexus One, but the MP3 decode is too slow on Droid. The audio playback starts to skip if we put the Droid under load. We are not permitted to decode the MP3 data to SD card, but I know that's not our problem anyways. We didn't write our own MP3 decoder, but used MPADEC (http://sourceforge.net/projects/mpadec/). It's free and was easy to integrate with our program. We compile it with the NDK. After exhaustive analysis with various profiling tools, we're convinced that it's this decoder that is falling behind. Here's the options we're thinking about: Find another MP3 decoder that we can compile with the Android NDK. This MP3 decoder would have to be either optimized to run on mobile ARM devices or maybe use integer-only math or some other optimizations to increase performance. Since the built-in Android MediaPlayer service will take URLs, we might be able to implement a tiny HTTP server in our program and serve the MediaPlayer with the decrypted MP3s. That way we can take advantage of the built-in MP3 decoder. Get access to the built-in MP3 decoder through the NDK. I don't know if this is possible. Does anyone have any suggestions on what we can do to speed up our MP3 decoding? -- Rob Sz

Using MVC2 to update an Entity Framework v4 object with foreign keys fails

- by jbjon

With the following simple relational database structure: An Order has one or more OrderItems, and each OrderItem has one OrderItemStatus. Entity Framework v4 is used to communicate with the database and entities have been generated from this schema. The Entities connection happens to be called EnumTestEntities in the example. The trimmed down version of the Order Repository class looks like this: public class OrderRepository { private EnumTestEntities entities = new EnumTestEntities(); // Query Methods public Order Get(int id) { return entities.Orders.SingleOrDefault(d => d.OrderID == id); } // Persistence public void Save() { entities.SaveChanges(); } } An MVC2 app uses Entity Framework models to drive the views. I'm using the EditorFor feature of MVC2 to drive the Edit view. When it comes to POSTing back any changes to the model, the following code is called: [HttpPost] public ActionResult Edit(int id, FormCollection formValues) { // Get the current Order out of the database by ID Order order = orderRepository.Get(id); var orderItems = order.OrderItems; try { // Update the Order from the values posted from the View UpdateModel(order, ""); // Without the ValueProvider suffix it does not attempt to update the order items UpdateModel(order.OrderItems, "OrderItems.OrderItems"); // All the Save() does is call SaveChanges() on the database context orderRepository.Save(); return RedirectToAction("Details", new { id = order.OrderID }); } catch (Exception e) { return View(order); // Inserted while debugging } } The second call to UpdateModel has a ValueProvider suffix which matches the auto-generated HTML input name prefixes that MVC2 has generated for the foreign key collection of OrderItems within the View. The call to SaveChanges() on the database context after updating the OrderItems collection of an Order using UpdateModel generates the following exception: "The operation failed: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. When a change is made to a relationship, the related foreign-key property is set to a null value. If the foreign-key does not support null values, a new relationship must be defined, the foreign-key property must be assigned another non-null value, or the unrelated object must be deleted." When debugging through this code, I can still see that the EntityKeys are not null and seem to be the same value as they should be. This still happens when you are not changing any of the extracted Order details from the database. Also the entity connection to the database doesn't change between the act of Getting and the SaveChanges so it doesn't appear to be a Context issue either. Any ideas what might be causing this problem? I know EF4 has done work on foreign key properties but can anyone shed any light on how to use EF4 and MVC2 to make things easy to update; rather than having to populate each property manually. I had hoped the simplicity of EditorFor and DisplayFor would also extend to Controllers updating data. Thanks

JQuery UI Autocomplete Syntax

- by djs22

Can someone help me understand the following code? I found it here. It takes advantage of the JQuery UI Autocomplete with a remote source. I've commented the code as best I can and a more precise question follows it. $( "#city" ).autocomplete({ source: function( request, response ) { //request is an objet which contains the user input so far // response is a callback expecting an argument with the values to autocomplete with $.ajax({ url: "http://ws.geonames.org/searchJSON", //where is script located dataType: "jsonp", //type of data we send the script data: { //what data do we send the script featureClass: "P", style: "full", maxRows: 12, name_startsWith: request.term }, success: function( data ) { //CONFUSED! response( $.map( data.geonames, function( item ) { return { label: item.name+(item.adminName1 ? ","+item.adminName1:"")+","+item.countryName, value: item.name } } ) ); } }); } }); As you can see, I don't understand the use of the success function and the response callback. I know the success function literal is an AJAX option which is called when the AJAX query returns. In this case, it seems to encapsulate a call to the response callback? Which is defined where? I thought by definition of a callback, it should be called on its own? Thanks!

SQLXML with Windows 2008 and SQL Server 2008

- by Rafa G. Argente

Hi all, I have an application that uses SQLXML to access data on the database. We have it working on a Windows 2003 server and SQL Server 2005. Now the client wants to install it on Windows 2008 and SQL Server 2008 and we are getting errors like: Microsoft.Data.SqlXml.SqlXmlException: Class not registered --- System.Runtime.InteropServices.COMException (0x80040154): Class not registered at Microsoft.Data.SqlXml.Common.UnsafeNativeMethods. ISQLXMLCommandManagedInterface.ExecuteToOutputStream() at Microsoft.Data.SqlXml.SqlXmlCommand.innerExecute(Stream strm) ... etc etc This is driving me crazy. SQLXML is quite an obsolete technology, and we are trying to use it with the latest SO. I can't find official information about SQLXML and Windows 2008, it seems it's not officially supported but they don't say it's not supported either. The SQLXML4.0SP1 installation seems to work fine, but it seems like it fails on runtime. Do you have any ideas? Has someone tried anything like this?

Linq-to-Sql IIS7 Login failed for user ‘DOMAIN\MACHINENAME$’

- by cfdev9

I am encountering unexpected behaviour using Linq-to-sql DataContext. When I run my application locally it works as expected however after deploying to a test server which runs IIS7, I get an error Login failed for user ‘DOMAIN\MACHINENAME$’ when attempting to open objects from the DataContext. This code explains the error, which breaks on the very last line with the error "System.Data.SqlClient.SqlException: Login failed for user". var connStr ="Data Source=server;Initial Catalog=Test;User Id=testuser;Password=password"; //Test 1 var conn1 = new System.Data.SqlClient.SqlConnection(connStr); var cmdString = "SELECT COUNT(*) FROM Table1"; var cmd = new System.Data.SqlClient.SqlCommand(cmdString, conn1); conn1.Open(); var count1 = cmd.ExecuteScalar(); conn1.Close(); //Test 2 var conn2 = new System.Data.SqlClient.SqlConnection(connStr); var context = new TestDataContext(conn2); var count2 = context.Table1s.Count(); The connection string is not even using integrated security, so why is Linq-to-sql trying to connect as a specific user? If I change the server name in the connection string I get a different error so its using atleast part of the connection string, but apparently ignoring the UserId and Password. Very confused.
