  • ADO.NET: Can't connect to mdf database file

    - by Nabo
    I'm writing an application that uses a SQL Server 2005 database. In the connection string i'm specifying the mdf file like this: connstr = @"Data Source=.\SQLEXPRESS; AttachDbFilename=" + fileLocation + "; Integrated Security=True; User Instance=True"; When i execute the code: public static void forceConnection() { try { conn = new SqlConnection(connstr); conn.Open(); } catch (Exception e) { MessageBox.Show(e.Message, "Erro", MessageBoxButtons.OK, MessageBoxIcon.Error); } finally { if(conn != null) conn.Close(); } } I receive an exception: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) This code works on XP but not in Vista.. I tryed run Visual Studio in admin mode and moved the mdf file to "user data" folders but the error persists.. Any help? Thanks!

  • Where is the windows app installed + .NET + VS2005

    - by The King
    I deployed a windows application in the following website http://StagingServer/MyProgs/MPP/ on my intranet site, using the Publish Wizard of VS 2005... I accepted all defaults (including Offline support). My users were also able to install the same from the path specified. But when I try to find out the exact location of the EXE in the client, it is not pointing anywhere. I also tried a file search but in vain. Initially I thought the application is running from the server itself, but we were able to start the app, even when the server is down (ofcourse it takes more time to search for updates initially). Ps : The app is showing even in control panel... Raja

  • Call .NET Webservice with Android

    - by Lasse P
    Hi, I know this question has been asked here before, but I don't think those answers were adequate for my needs. We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods: SOAP solution: Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, any suggestion? What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution? JSON solution: There is a few classes in the Android sdk that will let me parse JSON, but does it support generic parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you guys have any experince with either of those libraries? So i guess the big question is, what method to go with? I hope you can help me out. Thanks in advance :-)

  • .NET Web Service Proxy is adding special characters in XML

    - by xkingpin
    My web service proxy seems to be adding special characters like "*" and "#" etc. within the xml nodes. My proxy created lists using arrays of objects. I am trying to create a generic list and then doing list.ToArray() to set the proxy MyProxyObject[] object. Is this the cause of the problem I am having? I plan on running fiddler on the request later but it is over SSL and I do not have access to the URL at the moment. Here is an example of the XML that is generated: <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> * <soap:Body> o I'm a little concerned because the special characters are even occuring before the array nodes

  • Partioning the Table into .net - Creating columner database.

    - by Omky
    Hello Geeks, I am developing some tool for BI. There are terms like Fact, Dimensions and Measures. My application will connect to the normal database and read the data from that table. Now, I want to convert all this data into columnar database. That is all the columns from this table will be transfer into 3 tables each. Consider below table:- ID Product 1 XYZ 2 ABC 3 ABC Now, I want to convert the Product column i.e. dimension into 3 tables. dim_product_table:- ID Product 1 XYZ 2 ABC dim_product_fmk(fact map by key):- Where we will store key-value pair of Key Row 1 1 1 2 2 3 dim_product_fmr(fact map by row):- The above table will be reversed. Row Key 1 1 2 1 3 2 The another requirement is all above table should be generated dynamically and I should be able to JOIN all those. Can anybody help me? Thanks in advance.

  • Confirm box always displays first (javascript, jQuery, .Net)

    - by Jan-Frederik Carl
    Hello, I have a jQuery-Script to accomplish the following tasks: if a gridview in my form contains a row with a certain id, it has to be marked red. a confirm dialogue has to pop up to ask the user if he wants to do this or that. I built this code: if (response == "EntryInList") { $('#entryListContainer div table tbody tr').each(function() { if ($(this).attr('id') == 'entry_' + $('#<%= txtProductNumber.ClientID %>').val()) { $(this).css("color", "red"); } } ); if (!confirm("Entry already exists. Really overwrite?")) { jQuery('#<%= txtProductNumber.ClientID %>').val(''); jQuery('#<%= txtCount.ClientID %>').val(''); jQuery('#<%= txtProductNumber.ClientID %>').focus(); return false; } } As a result, the confirm box pops up first, without the row being turned red. Only after using the box, it becomes red. How would I get the row to be turned red at once? Another of my problems is that the confirm box denies my page to be scrolled down. But I would like to do this if the gridview is longer than the entire page.

  • asp.net mvc route clashing with physical path in IIS7

    - by Andrew Bullock
    I'm messing about with controller organisation and I've hit a problem. If I have the following physical structure /Home/HomeController.cs /Home/Index.aspx /Home/About.aspx and I request the URI: /Home/Index I get a 403 Directory Listing Denied :( (im using a custom IControllerFactory and IViewEngine to look in this non-default path) Why is this happening? (I know the 403 is because its hitting the /Home folder, but why is it hitting the folder?) Why doesn't the UrlRoutingModule rewrite the route and let the controller pick up the request? Application_BeginRequest fires, but then it seems to pass control back to IIS to try and serve from the filesystem. Is it the UrlRoutingModule that defaults to a physical path if it exists before rewriting? Is there a way to make this work? N.B. Please don't suggest relocating my controllers etc. I know this is an obvious option, but that isn't the question ;) Using IIS7 In Integrated Mode Thanks

  • error handling in asp.net

    - by user98454
    Hi How can i pass the different types of errors from Data access layer to presentation layer? suppose if we take the northwind database scenario I want to delete the customer, so i selected one customer in ui and clicked the "delete" button.It internally calls the "delete" in data access layer. The prerequisite for deleting the customer is that the customer doesn't have any orders.So in data access layer we wil check whether that customer has any orders.If the customer has orders how can we pass the message from dal to presentation layer that the customer has orders and we don't delete. Am i doing right?is there any other ways to deal with this type? Thanks in advance

  • Pass parameters to a user control - asp.net

    - by Cristian Boariu
    Hi, I have this user control: <user:RatingStars runat="server" product="<%= getProductId() %>" category="<%= getCategoryId() %>"></user:RatingStars> You see that i fill the product and category by calling two methods: public string getProductId() { return productId.ToString(); } public string getCategoryId() { return categoryId.ToString(); } I do not understand why, in the user control, when i take the data received (product and category) it gives me "<%= getProductId() %" instead of giving the id received from that method... Any help would be kindly appreciated...

  • Sending out 20,000+ emails with asp.net

    - by Kyle
    I am writing an application that will need to send a massive amount of emails to our students who will be selected from our database (each email will be personalized to the extent that will include their name, course of study etc...so needs to be sent one at a time). I could do this looping over an SmtpClient, but I'm afraid that with the numbers I'm trying to send, I'll ultimately run into timeout issues or my thread being killed because of lack of machine resources. At this point I'm just looking for suggestions of a better way to handle this, or if looping over SmtpClient is an ok solution, how I should go about handling it to prevent what I posted above. Would a web service be a better alternative? Please advise, TIA

  • Using external javascript files with asp.net MVC

    - by twal
    I have some javascript inwhich I am using such helpers as var url = <%=ResolveUrl("~/controller/action") %> When the javascript is embeded in the .aspx page using the <script> tag everything works fine When I move it out to an external file those scripts that have the helper methods do not work. Other scripts do just the ones with the var url = <%=ResolveUrl("~/controller/action") %> do not. Are these not possible to use in external javascript files?? I would like to get all of my javascript out of the aspx files if I can. thanks!

  • Regular Expression .net flavor

    - by user1440109
    Dont ask how this works but currently it does ("^\|(.?)\|*$")....kinda. This removes all extra pipes...part one....I have searched all over no anwser yet. I am using VB2011 beta...asp web form......vb coding though! I want to capture special character pipe (|) which is used to seperate words...i.e. car|truck|van|cycle problem is users lead with, trail with, use multiple, and use spaces before and after...i.e. |||car||truck | van || cycle. another example: george bush|micheal jordon|bill gates|steve jobs <-- this would be correct but when I do remove space it takes correct space out. so I want to get rid of whitespace leading, trailing, any space before | and space after | and only allow one pipe (|)....in between alphanumeric of course.

  • .NET, ASHX, "Server cannot append header after HTTP headers have been sent" after sending PDF Streem

    - by Inturbidus
    I visit my ASHX file, and it outputs a PDF perfectly. If I visit the very same ASHX with a different query string (I append DateTime.Now.Ticks to the end each visit), and I get this error: Server cannot append hader after HTTP headers have been sent. My code is below: copy.CloseStream = false; document.Close(); var r = context.Response; r.ExpiresAbsolute = DateTime.Now; r.BufferOutput = true; r.ContentType = "application/pdf"; r.AppendHeader("Content-Type", r.ContentType); r.AppendHeader("Content-disposition", "inline; filename=" + context.Server.UrlEncode(formType.File_Name)); r.BinaryWrite(copyStream.ToArray()); r.StatusCode = 200; r.End(); originalReader.Close(); copy.CloseStream = true; copy.Close(); There is no other place in this code that headers are sent. You are seeing the entire interaction with the Response object. I've tried to use r.Flush(); and r.End(); I've also tried not sending them if they are already there, but this causes other issues.
