• C# StreamReader.ReadLine() - Need to pick up line terminators

  - by Tony Trozzo

  I wrote a C# program to read an Excel .xls/.xlsx file and output to CSV and Unicode text. I wrote a separate program to remove blank records. This is accomplished by reading each line with StreamReader.ReadLine(), and then going character by character through the string and not writing the line to output if it contains all commas (for the CSV) or all tabs (for the Unicode text). The problem occurs when the Excel file contains embedded newlines (\x0A) inside the cells. I changed my XLS to CSV converter to find these new lines (since it goes cell by cell) and write them as \x0A, and normal lines just use StreamWriter.WriteLine(). The problem occurs in the separate program to remove blank records. When I read in with StreamReader.ReadLine(), by definition it only returns the string with the line, not the terminator. Since the embedded newlines show up as two separate lines, I can't tell which is a full record and which is an embedded newline for when I write them to the final file. I'm not even sure I can read in the \x0A because everything on the input registers as '\n'. I could go character by character, but this destroys my logic to remove blank lines. Any ideas would be greatly appreciated.

• Exception using Querytables in Excel Automation

  - by sam

• NserviceBus throws exception when referencing a Nettiers assembly

  We use nettiers as a our data layer, and we recently have started looking at using NServiceBus, but we have hit a wall. We have a windows service which hosts NSB and references our Nettiers assembly. the service is throwing an exception when the following line is encountered. var Bus = Configure.With().SpringBuilder() .XmlSerializer() .MsmqTransport() .IsTransactional(false) .PurgeOnStartup(false) .UnicastBus() .ImpersonateSender(false) .CreateBus() .Start(); the exceptions that is throw is: Unable to load one or more of the requested types.

• EL syntax error: Expression cannot start with binary operator

  - by auser

  Anyone have any creative ideas for how I can solve this warning? EL syntax error: Expression cannot start with binary operator caused by the following code: String.format("#{myController.deleteItemById(%d)}", getId()) My code looked like this before: "#{myController.deleteItemById(" + getId() + ")}" but this caused eclipse to generate the following warning: EL syntax error: String is not closed UPDATE: @ManagedBean(name = "myController") @ViewScoped public class MyController implements Serializable { private long id; private HtmlPanelGroup panel; public long getId() {return this.id; } private void getPanel() { /// bunch of code for programatically creating a form HtmlCommandButton deleteButton = new HtmlCommandButton(); deleteButton.setId(id); deleteButton.setValue(value); deleteButton.setActionExpression(/* EL expression used here */); } } <?xml version='1.0' encoding='UTF-8' ?> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:ui="http://java.sun.com/jsf/facelets"> <!-- some other elements removed for the sake of clarity --> <h:body> <h:panelGroup binding="#{myController.panel}" /> </h:body> </html>

• Asp.Net membership via ASP.NET Website Administrator Tool

  - by luppi

  I created a database with aspnet_regsql, the database was created in sql sever 2008 and not in data folder in my project (do I need to move it to the folder manually?). Next, in Web Site Administration Tool I went to provider section and clicked don Test button. I got an error: Could not establish a connection to the database. If you have not yet created the SQL Server database, exit the Web Site Administration tool, use the aspnet_regsql command-line utility to create and configure the database, and then return to this tool to set the provider. Maybe I need to set something in a web.config, like membership settings or connection strings (or ASP.NET Website Administrator Tool should create those settings for me)? Update: Maybe it happens because I am using SQL server 2008 full and not express? Update 2: After setting membership section and connection string to my aspnetdb database in Web Site Administration Tool I've opened security-Security Setup Wizard-Define Roles (stage 4) I got this error: An error was encountered. Please return to the previous page and try again. The following message may help in diagnosing the problem: Unable to connect to SQL Server database. at System.Web.Administration.WebAdminPage.CallWebAdminHelperMethod(Boolean isMembership, String methodName, Object[] parameters, Type[] paramTypes) at ASP.security_wizard_wizardpermission_ascx.OnInit(EventArgs e) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Control.InitRecursive(Control namingContainer) at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

• "The specified view is invalid" in call to LimitedWebPartManager.AddWebPart in SharePoint 2010

  - by Lee Richardson

  This code used to work in WSS 3.0 / MOSS 2007 in FeatureReceiver.FeatureActivated: using (SPLimitedWebPartManager limitedWebPartManager = Site.GetLimitedWebPartManager("default.aspx", PersonalizationScope.Shared)) { ListViewWebPart listViewWebPart = new ListViewWebPart { Title = title, ListName = list.ID.ToString("B").ToUpper(), ViewGuid = view.ID.ToString("B").ToUpper() }; limitedWebPartManager.AddWebPart(listViewWebPart, zone, position); } I'm trying to convert to SharePoint 2010 and it now fails with: System.ArgumentException: The specified view is invalid. at Microsoft.SharePoint.SPViewCollection.get_Item(Guid guid) at Microsoft.SharePoint.WebPartPages.ListViewWebPart.EnsureListAndView(Boolean requireFullBlownViewSchema) at Microsoft.SharePoint.WebPartPages.ListViewWebPart.get_AppropriateBaseViewId() at Microsoft.SharePoint.WebPartPages.SPWebPartManager.AddWebPartInternal(SPSupersetWebPart superset, Boolean throwIfLocked) at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPartInternal(WebPart webPart, String zoneId, Int32 zoneIndex, Boolean throwIfLocked) at Microsoft.SharePoint.WebPartPages.SPLimitedWebPartManager.AddWebPart(WebPart webPart, String zoneId, Int32 zoneIndex) Interestingly enough when I run it from a unit test it works, it only fails in FeatureActivated. When I debug with Reflector it is failing on this line: this.view = this.list.LightweightViews[new Guid(this.ViewGuid)]; list.LightweightViews only returns one view, the default view, even though list.Views returns all of them. I have no idea what LightweightViews is supposed to mean and I'm running out of ideas. Anyone else got any?

• Crystal Reports Reportviewer - Set Datasource Dynamically Not Working :argh:

  - by Albert

  I'm running CR XI, and accessing .RPT files through a ReportViewer in my ASP.NET pages. I've already got the following code, which is supposed to set the Report Datasource dynamically. rptSP = New ReportDocument Dim rptPath As String = Request.QueryString("report") rptSP.Load(rptPath.ToString, 0) Dim SConn As New System.Data.SqlClient.SqlConnectionStringBuilder(ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) rptSP.DataSourceConnections(SConn.DataSource, SConn.InitialCatalog).SetConnection(SConn.DataSource, SConn.InitialCatalog, SConn.UserID, SConn.Password) Dim myConnectionInfo As ConnectionInfo = New ConnectionInfo myConnectionInfo.ServerName = SConn.DataSource myConnectionInfo.DatabaseName = SConn.InitialCatalog myConnectionInfo.UserID = SConn.UserID myConnectionInfo.Password = SConn.Password 'Two new methods to loop through all objects and tables contained in the requested report and set 'login credentials for each object and table. SetDBLogonForReport(myConnectionInfo, rptSP) SetDBLogonForSubreports(myConnectionInfo, rptSP) Me.CrystalReportViewer1.ReportSource = rptSP But when I go into each .RPT file, and open up the Database Expert section, there is obviously still servernames hardcoded in there, and the code listed above doesn't seem to be able to change the servernames that are hardcoded there. I say this because I have training and production environments. When the .RPT file is hardcoded with my production server, and I open it on my training server with the code above (and the web.config has the training server in the connection string), I get the ol: Object reference not set to an instance of an object. And then if I go into the .RPT file, and change over the datasource to the training server, and try to open it again, it works fine. Why doesn't the code above overwrite the .RPT files datasource? How can I avoid having to open up each .RPT and change the datasource when migrating reports from server to server? Is there a setting in the .RPT file I'm missing or something?

How is possible to remove an element from the xpath to get things work? do I have to use .xpath twice to extract data if not using full xpath? why I cannot make .at_xpath working to extract data? it works nicely here what is the difference?

• WCF Web Service Gives 404 error in Azure

  - by landyman

  I'm new to using WCF and Azure, but I have a WCF Web Service that works correctly when debugging in Visual Studio. I set the startup project to Azure, and I get 404 errors for any URL I try related to the service. Here is what I think is relavant code: From IWebService.cs [OperationContract] [WebGet(UriTemplate = "GetData/Xml?value={value}", ResponseFormat=WebMessageFormat.Xml)] string GetDataXml(string value); and from Web.config: <system.serviceModel> <services> <service name="WebService" behaviorConfiguration="WebServiceBehavior"> <!-- Service Endpoints --> <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="WebEndpointBehavior"></endpoint> <endpoint address="ws" binding="wsHttpBinding" contract="IWebService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WebServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebEndpointBehavior"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> I have tried changing the binding to 'basicHttpBinding', but that had no luck. Thanks in advance for any help!

• Serializing java objects with respect to xml schema loaded at runtime

  - by kohomologie

  I call an XML document three-layered if its structure is laid out as following: the root element contains some container elements (I'll call them entities), each of them has some simpleType elements inside (I'll call them properties). Something like that: <data> <spaceship> <number>1024</number> <name>KTHX</name> </spaceship> <spaceship> <number>1624</number> <name>LEXX</name> </spaceship> <knife> <length>10</length> </knife> </data> where spaceship is an entity, and number is a property. My problem is stated below: Given schema: an arbitrary xsd file describing a three-layered document, loaded at runtime. xmlDocument: an xml document conforming to the schema. Create A Map<String, Map <String, Object>> containing data from the xmlDocument, where first key corresponds to entity, second key correponds to this entity's property, and the value corresponds to this property's value, after casting it to a proper java type (for example, if the schema sets the property value to be xs:int, then it should be cast to Integer). What is the easiest way to achieve this result with existing libraries? P. S. JAXB is not really an option here. The schema might be arbitrary and unknown at compile-time. Also I wish to avoid an excessive use of reflection (associated with converting the beans to maps). I'm looking for something that would allow me to make the typecasts while xml is being parsed.

• Writing a docx file to a BLOB using Java 1.4 inside Oracle 10g

  - by Jon Renaut

  I'm trying to generate a blank docx file using Java, add some text, then write it to a BLOB that I can return to our document processing engine (a custom mess of PL/SQL and Java). I have to use the 1.4 JVM inside Oracle 10g, so no Java 1.5 stuff. I don't have a problem writing the docx to a file on my local machine, but when I try to write to BLOB, I'm getting garbage. Am I doing something dumb? Any help is appreciated. Note in the code below, all the get[name]Xml() methods return an org.w3c.dom.Document. public void save(String fileName) throws Exception { ZipOutputStream zos = new ZipOutputStream(new FileOutputStream(fileName)); addEntry(zos, getDocumentXml(), "word/document.xml"); addEntry(zos, getContentTypesXml(), "[Content_Types].xml"); addEntry(zos, getRelsXml(), "_rels/.rels"); zos.flush(); zos.close(); } public java.sql.BLOB save() throws Exception { java.sql.Connection conn = DbUtilities.openConnection(); BLOB outBlob = BLOB.createTemporary(conn, true, BLOB.DURATION_SESSION); outBlob.open(BLOB.MODE_READWRITE); ZipOutputStream zos = new ZipOutputStream(outBlob.setBinaryStream(0L)); addEntry(zos, getDocumentXml(), "word/document.xml"); addEntry(zos, getContentTypesXml(), "[Content_Types].xml"); addEntry(zos, getRelsXml(), "_rels/.rels"); zos.flush(); zos.close(); return outBlob; } private void addEntry(ZipOutputStream zos, Document doc, String fileName) throws Exception { Transformer t = TransformerFactory.newInstance().newTransformer(); ByteArrayOutputStream baos = new ByteArrayOutputStream(); t.transform(new DOMSource(doc), new StreamResult(baos)); ZipEntry ze = new ZipEntry(fileName); byte[] data = baos.toByteArray(); ze.setSize(data.length); zos.putNextEntry(ze); zos.write(data); zos.flush(); zos.closeEntry(); }

• JQuery BlockUI with UpdatePanel Viewstate Issue

  - by Chris

  I am using BlockUI to show a modal. Within the blocked modal I have an update panel. Within the update panel I have a textbox and a button that submits the content back to the server. Everything works fine up to this point (the blockUI is called, the modal appears, and the button performs the postback). However, when the button's click event is fired the value for the textbox is consistently empty even if text was entered. When the update panel updates the textbox shows up blank. It appears that this may be some sort of viewstate issue and I haven't turned off viewstate. <a href="javascript:$.blockUI({ message: $('#divTest') });">SHOW MODAL</a> <div id="divTest" style="display: none;"> <asp:UpdatePanel ID="upTest" UpdateMode="Conditional" runat="server"> <ContentTemplate> <asp:TextBox ID="txtTestVS" runat="server" /><br /> <asp:Button ID="cmdTest" Text="TEST" OnClick="cmdTest_Click" UseSubmitBehavior="false" runat="server" /> </ContentTemplate> </asp:UpdatePanel> SERVER-SIDE: protected void cmdTest_Click(object sender, EventArgs e) { string x = txtTestVS.Text; } String "x" always equal "".

• Spring MVC jQuery remote validation

  - by raulsan

  Hi, I am using Spring MVC on the server side, but in one of the pages I decided to create an AJAX validation with jQuery rather than the default Spring validation. Everything works great, except when I have to do a remote validation to check if a "title" already exists. For the javascript I have the following: var validator = $("form").validate({ rules: { title: { minlength: 6, required: true, remote: { url: location.href.substring(0,location.href.lastIndexOf('/'))+"/checkLocalArticleTitle.do", type: "GET" } }, html: { minlength: 50, required: true } }, messages: { title: { required: "A title is required.", remote: "This title already exists." } } }); Then, I use Spring-Json to make this validation and give a response: @RequestMapping("/checkLocalArticleTitle.do") public ModelAndView checkLocalArticleTitle(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { Map model = new HashMap(); String result = "FALSE"; try{ String title = request.getParameter("title"); if(!EJBRequester.articleExists(title)){ result = "TRUE"; } }catch(Exception e){ System.err.println("Exception: " + e.getMessage()); } model.put("result",result); return new ModelAndView("jsonView", model); } However, this does not work and the field "title" is never validated. I think the reason for this is that I am returning an answer in the manner: {result:"TRUE"} when in fact, the answer should be: {"TRUE"} I don't know how to return a single response like this one using a ModelAndView answer. Another thing that is not working is the customized message for the "remote" validation: messages: { title: { required: "A title is required.", remote: "This title already exists." } }, The required message works, but not the remote message. I looked around, but I didn't see many people using Spring and jQuery at the same time. I would appreciate some help here.

However, when we configure the IIS Application Pool to run the code under a different Identity, we get the following: System.Security.Cryptography.CryptographicException: The system cannot find the file specified. at System.Security.Cryptography.Utils.CreateProvHandle(CspParameters parameters, Boolean randomKeyContainer) at System.Security.Cryptography.RSACryptoServiceProvider.ImportParameters(RSAParameters parameters) at System.Security.Cryptography.RSA.FromXmlString(String xmlString) The code is something like this: byte[] input; byte[] output; string private_key_xml; var provider = new System.Cryptography.RSACryptoServiceProvider(this.m_key.Key_Size); provider.FromXmlString(private_key_xml); // Fails Here when Application Pool Identity != Network Service ouput = provider.Decrypt(input, false); // False = Use PKCS#1 v1.5 Padding There are resources which attempt to answer it by stating that you should give the user read access to the machine key store - however there is no definitive answer to solve this issue. Environment: IIS 6.0, Windows Server 2003 R2, .NET 3.5 SP1

  Hi, I was trying http-cleint tutorials from svn.apache.org. While running the application I am getting the following error in console.

• Suppress Null Value Types from Being Emitted by XmlSerializer

  - by Ben Griswold

  Please consider the following Amount value type property which is marked as a nullable XmlElement: [XmlElement(IsNullable=true)] public double? Amount { get ; set ; } When a nullable value type is set to null, the C# XmlSerializer result looks like the following: <amount xsi:nil="true" /> Rather than emitting this element, I would like the XmlSerializer to suppress the element completely. Why? We're using Authorize.NET for online payments and Authorize.NET rejects the request if this null element exists. The current solution/workaround is to not serialize the Amount value type property at all. Instead we have created a complementary property, SerializableAmount, which is based on Amount and is serialized instead. Since SerializableAmount is of type String, which like reference types are suppressed by the XmlSerializer if null by default, everything works great. /// <summary> /// Gets or sets the amount. /// </summary> [XmlIgnore] public double? Amount { get; set; } /// <summary> /// Gets or sets the amount for serialization purposes only. /// This had to be done because setting value types to null /// does not prevent them from being included when a class /// is being serialized. When a nullable value type is set /// to null, such as with the Amount property, the result /// looks like: &gt;amount xsi:nil="true" /&lt; which will /// cause the Authorize.NET to reject the request. Strings /// when set to null will be removed as they are a /// reference type. /// </summary> [XmlElement("amount", IsNullable = false)] public string SerializableAmount { get { return this.Amount == null ? null : this.Amount.ToString(); } set { this.Amount = Convert.ToDouble(value); } } Of course, this is just a workaround. Is there a cleaner way to suppress null value type elements from being emitted?

• Pivotcache problem using ado recordset into excel

  I'm having a problem with runtime error 1004 at the last line. I'm bringing in an access query into excel 2007. I know the recordset is ok as I can see the fields and data.

• ASP.NET MVC 2 - Html.DropDownList not working in an AJAX form

  - by Jacob

  I am trying to create an MVC 2 solution and I have run into the following problem: Index.aspx: <% using(Ajax.BeginForm("Forms", new AjaxOptions{UpdateTargetId="form", HttpMethod="POST"})) { %> <h3>Input: </h3> <p><%= Html.DropDownList("dropDown")%> <input type="submit" value="Select Mission" /></p> <% } %> HomeController.cs: public ActionResult Index() { var list = new [] { "item1", "item2", "item3" }; ViewData["dropDown"] = new SelectList(list); return View(); } public ActionResult Forms(string dropDown) { if (dropDown == null || dropDown == "") ViewData["txt"] = "Ahhh..."; else ViewData["txt"] = "You entered: " + dropDown; return PartialView("Form", dropDown); } Form.ascx: <%: ViewData["txt"] % This does not work. However, the whole thing does work if I use an Html.TextBox instead. For example: <div id="form"> <% using(Ajax.BeginForm("Forms", new AjaxOptions{UpdateTargetId="form", HttpMethod="POST"})) { %> <h3>Input: </h3> <%= Html.TextBox("textBox") %> <input type="submit" value="Select Mission" /></p> <% } %> </div> (and refactor the method in the controller so that it's argument is textBox instead of dropDown). My question is why does the AJAX form work for an Html.TextBox, but not for an Html.DropDownList, or what am I doing wrong? My only idea is that maybe the argument in the controller is not supposed to be of type string when using a DropDownList, but this is really just a guess. Thanks in advance.

• LINQ To SQL ignore unique constraint exception and continue

  - by Martin

  I have a single table in a database called Users Users ------ ID (PK, Identity) Username (Unique Index) I have setup a unique index on the Username table to prevent duplicates. I am then enumerating through a collection and creating a new user in the database for each item. What I want to do is just insert a new user and ignore the exception if the unique key constraint is violated (as it's clearly a duplicate record in that case). This is to avoid having to craft where not exists kind of queries. First off, is this going to be any more efficient or should my insert code be checking for duplicates instead? I'm drawn more to the database having that logic as this prevents any other type of client from inserting duplicate data. My other issue is related to LINQ To SQL. I have the following code: public class TestRepo { DatabaseDataContext database = new DatabaseDataContext(); public void Add(string username) { database.Users.InsertOnSubmit(new User() { Username = username }); } public void Save() { database.SubmitChanges(); } } And then I iterate over a collection and insert new users, ignoring any exceptions: TestRepo repo = new TestRepo(); foreach (var name in new string[] { "Tim", "Bob", "John" }) { try { repo.Add(name); repo.Save(); } catch { } } The first time this is run, great I have three users in the table. If I remove the second one and run this code again, nothing is inserted. I expected the first insert to fail with the exception, the second to succeed (as I just removed that item from the DB) and the third to then fail. What seems to be happening is that once the SqlException is thrown (even though the loop continues to iterate) all of the next inserts fail - even when there isn't a row in the table that would cause a unique violation. Can anyone explain this? P.S. The only workaround I could find was to instantiate the repo each time before the insert, then it worked exactly as excepted - indicating that it's something to do with the LINQ To SQL DataContext. Thanks.
