  • Mailing Address is forcing 2nd Record in CSV (DevExpress Controls)

    - by Gerhard Weiss
    My DevExpress CSV export has two lines per record. Rank Score,Prog.,Full Address 63.30 ,JIW ,1234 Whispering Pines Dr , ,Sometown MI 48316 62.80 ,JIW ,9876 Beagle Dr , ,Sometown Twp MI 48382 I would like to change it to one line because I want to do a Word Merge. (Unless Word can merge these two lines back together, which I do not thing it can do) Does the DevExpress XtraGrid ExportToText allow for this? A MemoEdit is being used by the XtraGrid and is initialized using the following code (Noticed the ControlChars.NewLine): Public ReadOnly Property FullAddress() As String Get Dim strAddress As System.Text.StringBuilder = New StringBuilder() If Not IsNullEntity Then strAddress.Append(Line1 + ControlChars.NewLine) If Not Line2 Is Nothing AndAlso Me.Line2.Length > 0 Then strAddress.Append(Line2 + ControlChars.NewLine) End If If Not Line3 Is Nothing AndAlso Me.Line3.Length > 0 Then strAddress.Append(Line3 + ControlChars.NewLine) End If strAddress.Append(String.Format("{0} {1} {2}", City, RegionCode, PostalCode)) If Me.Country <> "UNITED STATES" Then strAddress.Append(ControlChars.NewLine + Me.Country) End If End If Return strAddress.ToString End Get End Property Here is the export to CSV code: Dim saveFile As New SaveFileDialog With saveFile '.InitialDirectory = ClientManager.CurrentClient.Entity.StudentPictureDirectory .FileName = "ApplicantList.csv" .CheckPathExists = True .CheckFileExists = False .Filter = "All Files (*.*)|*.*" End With If saveFile.ShowDialog() = Windows.Forms.DialogResult.OK Then Dim PrintingTextExportOptions As New DevExpress.XtraPrinting.TextExportOptions(",", Encoding.ASCII) PrintingTextExportOptions.QuoteStringsWithSeparators = True ApplicantRankListViewsGridControl.ExportToText(saveFile.FileName, PrintingTextExportOptions) End If

  • Most efficient way to check for DBNull and then assign to a variable?

    - by ilitirit
    This question comes up occasionally but I haven't seen a satisfactory answer. A typical pattern is (row is a DataRow): if (row["value"] != DBNull.Value) { someObject.Member = row["value"]; } My first question is which is more efficient (I've flipped the condition): row["value"] == DBNull.Value; // Or row["value"] is DBNull; // Or row["value"].GetType() == typeof(DBNull) // Or... any suggestions? This indicates that .GetType() should be faster, but maybe the compiler knows a few tricks I don't? Second question, is it worth caching the value of row["value"] or does the compiler optimize the indexer away anyway? eg. object valueHolder; if (DBNull.Value == (valueHolder = row["value"])) {} Disclaimers: row["value"] exists. I don't know the column index of the column (hence the column name lookup) I'm asking specifically about checking for DBNull and then assignment (not about premature optimization etc). Edit: I benchmarked a few scenarios (time in seconds, 10000000 trials): row["value"] == DBNull.Value: 00:00:01.5478995 row["value"] is DBNull: 00:00:01.6306578 row["value"].GetType() == typeof(DBNull): 00:00:02.0138757 Object.ReferenceEquals has the same performance as "==" The most interesting result? If you mismatch the name of the column by case (eg. "Value" instead of "value", it takes roughly ten times longer (for a string): row["Value"] == DBNull.Value: 00:00:12.2792374 The moral of the story seems to be that if you can't look up a column by it's index, then ensure that the column name you feed to the indexer matches the DataColumn's name exactly. Caching the value also appears to be nearly twice as fast: No Caching: 00:00:03.0996622 With Caching: 00:00:01.5659920 So the most efficient method seems to be: object temp; string variable; if (DBNull.Value != (temp = row["value"]) { variable = temp.ToString(); } This was a good learning experience.

  • Detecting what changed in an HTML Textfield

    - by teehoo
    For a major school project I am implementing a real-time collaborative editor. For a little background, basically what this means is that two(or more) users can type into a document at the same time, and their changes are automatically propagated to one another (similar to Etherpad). Now my problem is as follows: I want to be able to detect what changes a user carried out onto an HTML textfield. They could: Insert a character Delete a character Paste a string of characters Cut a string of characters I want to be able to detect which of these changes happened and then notify other clients similar to "insert character 'c' at position 2" etc. Anyway I was hoping to get some advice on how I would go about implementing the detection of these changes? My first attempt was to consider the carot position before and after a change occurred, but this failed miserably. For my second attempt I was thinking about doing a diff on the entire contents of the textfields old and new value. Am I missing anything obvious with this solution? Is there something simpler?

  • Why does findstr not handle case properly (in some circumstances)?

    - by paxdiablo
    While writing some recent scripts in cmd.exe, I had a need to use findstr with regular expressions - customer required standard cmd.exe commands (no GnuWin32 nor Cygwin nor VBS nor Powershell). I just wanted to know if a variable contained any upper-case characters and attempted to use: > set myvar=abc > echo %myvar%|findstr /r "[A-Z]" abc > echo %errorlevel% 0 When %myvar% is set to abc, that actually outputs the string and sets errorlevel to 0, saying that a match was found. However, the full-list variant: > echo %myvar%|findstr /r "[ABCDEFGHIJKLMNOPQRSTUVWXYZ]" > echo %errorlevel% 1 does not output the line and it correctly sets errorlevel to 1. In addition: > echo %myvar%|findstr /r "^[A-Z]*$" > echo %errorlevel% 1 also works as expected. I'm obviously missing something here even if it's only the fact that findstr is somehow broken. Why does the first (range) regex not work in this case? And yet more weirdness: > echo %myvar%|findstr /r "[A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z]" abc > echo %myvar%|findstr /r "[A-Z][A-Z][A-Z]" > echo %myvar%|findstr /r "[A]" The last two above also does not output the string!!

  • Expression Tree with Property Inheritance causes an argument exception

    - by Adam Driscoll
    Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.

  • Can't select data from MySQL database: java.lang.NullPointerException

    - by Devel
    Hi, I'm trying to select data from database using this code: //DATABASE ResultSet rs; String polecenie; Statement st; String[] subj; public void polacz() { try { Class.forName("com.mysql.jdbc.Driver"); Connection pol=DriverManager.getConnection("jdbc:mysql://localhost:3306/testgenerator", "root", "pospaz"); st = pol.createStatement(); lblPolaczonoZBaza.setText("Polaczono z baza danych testgenerator"); } catch (Exception ek) { statusMessageLabel.setText("Can't connect to d: "+ek); } polecenie = "select * from subjects"; try { rs = st.executeQuery(polecenie); int i=0; while (rs.next()){ subj[i] = rs.getString("name"); i++; } st.close(); } catch (Exception ek) { statusMessageLabel.setText("Can't select data: "+ek); } } The second catch shows exception: java.lang.NullPointerException I looked everywhere and I can't find the solution. I'd be grateful for any help.

  • How do you replicate changes from one excel sheet to another in two separate excel apps?

    - by incognick
    This is all in C# .NET Excel Interop Automation for Office 2007. Say you create two excel apps and open the same workbook for each application: app = new Excel.ApplicationClass(); app2 = new Excel.ApplicationClass(); string fileLocation = "myBook.xslx"; workbook = app.Workbooks.Open(fileLocation, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); workbook2 = app2.Workbooks.Open(fileLocation, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing); Now, I want to replicate any changes that occur in workbook2, into workbook. I figured out I can hook up the SheetChanged event to capture cell changes: app.SheetChange += new Microsoft.Office.Interop.Excel.AppEvents_SheetChangeEventHandler(app_SheetChange); void app_SheetChange(object Sh, Microsoft.Office.Interop.Excel.Range Target) { Excel.Worksheet sheetReadOnly = (Excel.Worksheet)Sh; string changedRange = Target.get_Address(missing, missing, Excel.XlReferenceStyle.xlA1, missing, missing); Console.WriteLine("The value of " + sheetReadOnly.Name + ":" + changedRange + " was changed to = " + Target.Value2); Excel.Worksheet sheet = workbook.Worksheets[sheetReadOnly.Index] as Excel.Worksheet; Excel.Range range = sheet.get_Range(changedRange, missing); range.Value2 = Target.Value2; } How do you capture calculate changes? I can hook onto the calculate event but the only thing that is passed is the sheet, not the cells that were updated. I tried forcing an app.Calculate() or app.CalculateFullRebuild() but nothing updates in the other application. The change event does not get fired when formulas change (i.e. a slider control causes a SheetCalculate event and not a SheetChange event) Is there a way to see what formulas were updated? Or is there an easier way to sync two workbooks programmatically in real time?

  • Is 1/0 a legal Java expression?

    - by polygenelubricants
    The following compiles fine in my Eclipse: final int j = 1/0; // compiles fine!!! // throws ArithmeticException: / by zero at run-time Java prevents many "dumb code" from even compiling in the first place (e.g. "Five" instanceof Number doesn't compile!), so the fact this didn't even generate as much as a warning was very surprising to me. The intrigue deepens when you consider the fact that constant expressions are allowed to be optimized at compile time: public class Div0 { public static void main(String[] args) { final int i = 2+3; final int j = 1/0; final int k = 9/2; } } Compiled in Eclipse, the above snippet generates the following bytecode (javap -c Div0) Compiled from "Div0.java" public class Div0 extends java.lang.Object{ public Div0(); Code: 0: aload_0 1: invokespecial #8; //Method java/lang/Object."<init>":()V 4: return public static void main(java.lang.String[]); Code: 0: iconst_5 1: istore_1 // "i = 5;" 2: iconst_1 3: iconst_0 4: idiv 5: istore_2 // "j = 1/0;" 6: iconst_4 7: istore_3 // "k = 4;" 8: return } As you can see, the i and k assignments are optimized as compile-time constants, but the division by 0 (which must've been detectable at compile-time) is simply compiled as is. javac 1.6.0_17 behaves even more strangely, compiling silently but excising the assignments to i and k completely out of the bytecode (probably because it determined that they're not used anywhere) but leaving the 1/0 intact (since removing it would cause an entirely different program semantics). So the questions are: Is 1/0 actually a legal Java expression that should compile anytime anywhere? What does JLS say about it? If this is legal, is there a good reason for it? What good could this possibly serve?

  • WCF object parameter loses values

    - by Josh
    I'm passing an object to a WCF service and wasn't getting anything back. I checked the variable as it gets passed to the method that actually does the work and noticed that none of the values are set on the object at that point. Here's the object: [DataContract] public class Section { [DataMember] public long SectionID { get; set; } [DataMember] public string Title { get; set; } [DataMember] public string Text { get; set; } [DataMember] public int Order { get; set; } } Here's the service code for the method: [OperationContract] public List<Section> LoadAllSections(Section s) { return SectionRepository.Instance().LoadAll(s); } The code that actually calls this method is this and is located in a Silverlight XAML file: SectionServiceClient proxy = new SectionServiceClient(); proxy.LoadAllSectionsCompleted += new EventHandler<LoadAllSectionsCompletedEventArgs>(proxy_LoadAllSectionsCompleted); Section s = new Section(); s.SectionID = 4; proxy.LoadAllSectionsAsync(s); When the code finally gets into the method LoadAllSections(Section s), the parameter's SectionID is not set. I stepped through the code and when it goes into the generated code that returns an IAsyncResult object, the object's properties are set. But when it actually calls the method, LoadAllSections, the parameter received is completely blank. Is there something I have to set to make the proeprty stick between method calls?

  • Sendkeys problem from .NET program

    - by user203123
    THe code below I copied from MSDN with a bit of modification: [DllImport("user32.dll", CharSet = CharSet.Unicode)] public static extern IntPtr FindWindow(string lpClassName,string lpWindowName); DllImport("User32")] public static extern bool SetForegroundWindow(IntPtr hWnd); int cnt = 0; private void button1_Click(object sender, EventArgs e) { IntPtr calculatorHandle = FindWindow("Notepad", "Untitled - Notepad"); if (calculatorHandle == IntPtr.Zero) { MessageBox.Show("Calculator is not running."); return; } SetForegroundWindow(calculatorHandle); SendKeys.SendWait(cnt.ToString()); SendKeys.SendWait("{ENTER}"); cnt++; SendKeys.Flush(); System.Threading.Thread.Sleep(1000); } The problem is the number sequence in Notepad is not continuously. The first click always results 0 (as expected). but from the second click, the result is unpredictable (but the sequence is still in order, e.g. 3, 4, 5, 10, 14, 15, ....) If I click the button fast enough, I was able to get the result in continuous order (0,1,2,3,4,....) but sometimes it produces more than 2 same numbers (e.g. 0,1,2,3,3,3,4,5,6,6,6,7,8,9,...)

  • LINQ Query please help C#.Net.

    - by Paul Matthews
    I'm very new to LINQ and struggling to find the answers. I have a simple SQL query. Select ID, COUNT(ID) as Selections, OptionName, SUM(Units) as Units FROM tbl_Results GROUP BY ID, OptionName. The results I got were: '1' '4' 'Approved' '40' '2' '1' 'Rejected' '19' '3' '2' 'Not Decided' '12' Due to having to encrypt all my data in the database I'm unable to do sums. Therefore I have now brought back the data and decrypt it in the application layer. Results would be: '1' 'Approved' '10' '3' 'Not Deceided' '6' '2' 'Rejected' '19' '1' 'Approved' '15' '1' 'Approved' '5' '3' 'Not Deceided' '6' '1' 'Approved' '10' using a simple class I have called back the above results, and put them in a list class. public class results { public int ID {get;set;} public string OptionName {get;set;} public int Unit {get;set;} } I almost have the LINQ query to bring back the results like the SQL query at the top var q = from r in Results group p.Unit by p.ID int g select new {ID = g.Key, Selections = g.Count(), Units = g.Sum()}; How do I ensure my LINQ query also give me the Option Name? Also if I created a class called Statistics to hold my results how would I modify the LINQ query to give me list result set? public class results { public int ID {get;set;} public int NumberOfSelections { get; set; } public string OptionName {get;set;} public int UnitTotal {get;set;} }

  • Techniques for sharing a value among classes in a program

    - by Kenneth Cochran
    I'm using Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData) + "\MyProgram" As the path to store several files used by my program. I'd like to avoid pasting the same snippet of code all over the my applcation. I need to ensure that: The path cannot be accidentally changed once its been set The classes that need it have access to it. I've considered: Making it a singleton Using constructor dependency injection Using property dependency injection Using AOP to create the path where its needed. Each has pros and cons. The singleton is everyone's favorite whipping boy. I'm not opposed to using one but there are valid reasons to avoid it if possible. I'm already heavily using constructor injection through Castle Windsor. But this is a path string and Windsor doesn't handle system type dependencies very gracefully. I could always wrap it in a class but that seems like overkill for something as simple as a passing around a string value. In any case this route would add yet another constructor argument to each class where it is used. The problem I see with property injection in this case is that there is a large amount of indirection from the where the value is set to where it is needed. I would need a very long line of middlemen to reach all the places where its used. AOP looks promising and I'm planning on using AOP for logging anyway so this at least sounds like a simple solution. Is there any other options I haven't considered? Am I off base with my evaluation of the options I have considered?

  • Keeping the UI responsive while parsing a very large logfile

    - by Carlos
    I'm writing an app that parses a very large logfile, so that the user can see the contents in a treeview format. I've used a BackGroundWorker to read the file, and as it parses each message, I use a BeginInvoke to get the GUI thread to add a node to my treeview. Unfortunately, there's two issues: The treeview is unresponsive to clicks or scrolls while the file is being parsed. I would like users to be able to examine (ie expand) nodes while the file is parsing, so that they don't have to wait for the whole file to finish parsing. The treeview flickers each time a new node is added. Here's the code inside the form: private void btnChangeDir_Click(object sender, EventArgs e) { OpenFileDialog browser = new OpenFileDialog(); if (browser.ShowDialog() == DialogResult.OK) { tbSearchDir.Text = browser.FileName; BackgroundWorker bgw = new BackgroundWorker(); bgw.DoWork += (ob, evArgs) => ParseFile(tbSearchDir.Text); bgw.RunWorkerAsync(); } } private void ParseFile(string inputfile) { FileStream logFileStream = new FileStream(inputfile, FileMode.Open, FileAccess.Read, FileShare.ReadWrite); StreamReader LogsFile = new StreamReader(logFileStream); while (!LogsFile.EndOfStream) { string Msgtxt = LogsFile.ReadLine(); Message msg = new Message(Msgtxt.Substring(26)); //Reads the text into a class with appropriate members AddTreeViewNode(msg); } } private void AddTreeViewNode(Message msg) { TreeNode newNode = new TreeNode(msg.SeqNum); BeginInvoke(new Action(() => { treeView1.BeginUpdate(); treeView1.Nodes.Add(newNode); treeView1.EndUpdate(); Refresh(); } )); } What needs to be changed?

  • Virtual properties duplicated during serialization when XmlElement attribute used

    - by Laramie
    The Goal: XML serialize an object that contains a list of objects of that and its derived types. The resulting XML should not use the xsi:type attribute to describe the type, to wit the names of the serialized XML elements would be an assigned name specific to the derived type, not always that of the base class, which is the default behavior. The Attempt: After exploring IXmlSerializable and IXmlSerializable with eerie XmlSchemaProvider methods and voodoo reflection to return specialized schemas and an XmlQualifiedName over the course of days, I found I was able to use the simple [XmlElement] attribute to accomplish the goal... almost. The Problem: Overridden properties appear twice when serializing. The exception reads "The XML element 'overriddenProperty' from namespace '' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element." I attempted using a *Specified property (see code), but it didn't work. Sample Code: Class Declaration using System; using System.Collections.Generic; using System.Xml.Serialization; [XmlInclude(typeof(DerivedClass))] public class BaseClass { public BaseClass() { } [XmlAttribute("virt")] public virtual string Virtual { get; set; } [XmlIgnore] public bool VirtualSpecified { get { return (this is BaseClass); } set { } } [XmlElement(ElementName = "B", Type = typeof(BaseClass), IsNullable = false)] [XmlElement(ElementName = "D", Type = typeof(DerivedClass), IsNullable = false)] public List<BaseClass> Children { get; set; } } public class DerivedClass : BaseClass { public DerivedClass() { } [XmlAttribute("virt")] public override string Virtual { get { return "always return spackle"; } set { } } } Driver: BaseClass baseClass = new BaseClass() { Children = new List<BaseClass>() }; BaseClass baseClass2 = new BaseClass(){}; DerivedClass derivedClass1 = new DerivedClass() { Children = new List<BaseClass>() }; DerivedClass derivedClass2 = new DerivedClass() { Children = new List<BaseClass>() }; baseClass.Children.Add(derivedClass1); baseClass.Children.Add(derivedClass2); derivedClass1.Children.Add(baseClass2); I've been wrestling with this on and off for weeks and can't find the answer anywhere.

  • Why should I bother with unit testing if I can just use integration tests?

    - by CodeGrue
    Ok, I know I am going out on a limb making a statement like that, so my question is for everyone to convince me I am wrong. Take this scenario: I have method A, which calls method B, and they are in different layers. So I unit test B, which delivers null as a result. So I test that null is returned, and the unit test passes. Nice. Then I unit test A, which expects an empty string to be returned from B. So I mock the layer B is in, an empty string is return, the test passes. Nice again. (Assume I don't realize the relationship of A and B, or that maybe two differente people are building these methods) My concern is that we don't find the real problem until we test A and B togther, i.e. Integration Testing. Since an integration test provides coverage over the unit test area, it seems like a waste of effort to build all these unit tests that really don't tell us anything (or very much) meaningful. Why am I wrong?

    - by Mike
    Hi! I created a class that implements the FilterInvocationSecurityMetadataSource interface. I implemented it like this: public List<ConfigAttribute> getAttributes(Object object) { FilterInvocation fi = (FilterInvocation) object; Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal(); Long companyId = ((ExtenededUser) principal).getCompany().getId(); String url = fi.getRequestUrl(); // String httpMethod = fi.getRequest().getMethod(); List<ConfigAttribute> attributes = new ArrayList<ConfigAttribute>(); FilterSecurityService service = (FilterSecurityService) SpringBeanFinder.findBean("filterSecurityService"); Collection<Role> roles = service.getRoles(companyId); for (Role role : roles) { for (View view : role.getViews()) { if (view.getUrl().equalsIgnoreCase(url)) attributes.add(new SecurityConfig(role.getName() + "_" + role.getCompany().getName())); } } return attributes; } when I debug my application I see it reaches this class, it only reaches getAllConfigAttributes method, that is empty as I said, and return null. after that it prints this warning: Could not validate configuration attributes as the SecurityMetadataSource did not return any attributes from getAllConfigAttributes(). My aplicationContext- security is like this: <beans:bean id="filterChainProxy" class="org.springframework.security.web.FilterChainProxy"> <filter-chain-map path-type="ant"> <filter-chain filters="sif,filterSecurityInterceptor" pattern="/**" /> </filter-chain-map> </beans:bean> <beans:bean id="filterSecurityInterceptor" class="org.springframework.security.web.access.intercept.FilterSecurityInterceptor"> <beans:property name="authenticationManager" ref="authenticationManager" /> <beans:property name="accessDecisionManager" ref="accessDecisionManager" /> <beans:property name="securityMetadataSource" ref="filterSecurityMetadataSource" /> </beans:bean> <beans:bean id="filterSecurityMetadataSource" class="com.mycompany.filter.FilterSecurityMetadataSource"> </beans:bean> what could be the problem?

  • WMI Query Script as a Job

    - by Kenneth
    I have two scripts. One calls the other with a list of servers as parameters. The second query is designed to execute a WMI query. When I run it manually, it does this perfectly. When I try to run it as a job it hangs forever and I have to remove it. For the sake of space here is the relevant part of the calling script: ProcessServers.ps1 Start-Job -FilePath .\GetServerDetailsLight.ps1 -ArgumentList $sqlsrv,$destdb,$server,$instance GetServerDetailsLight.ps1 param($sqlsrv,$destdb,$server,$instance) $password = get-content C:\SQLPS\auth.txt | convertto-securestring $credentials = new-object -typename System.Management.Automation.PSCredential -argumentlist "DOMAIN\MYUSER",$password [System.Reflection.Assembly]::LoadWithPartialName('Microsoft.SqlServer.SMO') $box_id = 0; if ($sqlsrv.length -eq 0) { write-output "No data passed" break } function getinfo { param( [string]$svr, [string]$inst ) "Entered GetInfo with: $svr,$inst" $cs = get-wmiobject win32_operatingsystem -computername $svr -credential $credentials -authentication 6 -Verbose -Debug | select Name, Model, Manufacturer, Description, DNSHostName, Domain, DomainRole, PartOfDomain, NumberOfProcessors, SystemType, TotalPhysicalMemory, UserName, Workgroup write-output "WMI Results: $cs" } getinfo $server $instance write-output "Complete" Executed as a job it will show as 'running' forever: PS C:\sqlps> Start-Job -FilePath .\GetServerDetailsLight.ps1 -ArgumentList DBSERVER,LOGDB,SERVER01,SERVER01 Id Name State HasMoreData Location Command -- ---- ----- ----------- -------- ------- 21 Job21 Running True localhost param($sqlsrv,$destdb,... GAC Version Location --- ------- -------- True v2.0.50727 C:\WINDOWS\assembly\GAC_MSIL\Microsoft.SqlServer.Smo\10.0.0.0__89845dcd8080cc91\Microsoft.SqlServer.Smo.dll getinfo MSDCHR01 MSDCHR01 Entered GetInfo with: SERVER01,SERVER01 The last output I ever get is the 'Entered GetInfo with: SERVER01,SERVER01'. If I run it manually like so: PS C:\sqlps> .\GetServerDetailsLight.ps1 DBSERVER LOGDB SERVER01 SERVER01 The WMI query executes just as expected. I am trying to determine why this is, or at least a useful way to trap errors from within jobs. Thanks!

  • Is there a way to get an ASMX Web Service created in VS 2005 to receive and return JSON?

    - by Ben McCormack
    I'm using .NET 2.0 and Visual Studio 2005 to try to create a web service that can be consumed both as SOAP/XML and JSON. I read Dave Ward's Answer to the question How to return JSON from a 2.0 asmx web service (in addition to reading other articles at Encosia.com), but I can't figure out how I need to set up the code of my asmx file in order to work with JSON using jQuery. Two Questions: How do I enable JSON in my .NET 2.0 ASMX file? What's a simple jQuery call that could consume the service using JSON? Also, I notice that since I'm using .NET 2.0, I i'm not able to implement using System.Web.Script.Services.ScriptService. Here's my C# code for the demo ASMX service: using System; using System.Web; using System.Collections; using System.Web.Services; using System.Web.Services.Protocols; /// <summary> /// Summary description for StockQuote /// </summary> [WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class StockQuote : System.Web.Services.WebService { public StockQuote () { //Uncomment the following line if using designed components //InitializeComponent(); } [WebMethod] public decimal GetStockQuote(string ticker) { //perform database lookup here return 8; } [WebMethod] public string HelloWorld() { return "Hello World"; } } Here's a snippet of jQuery I found on the internet and tried to modify: $(document).ready(function(){ $("#btnSubmit").click(function(event){ $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "http://bmccorm-xp/WebServices/HelloWorld.asmx", data: "", dataType: "json" }) event.preventDefault(); }); });

  • Validation with State Pattern for Multi-Page Forms in ASP.NET

    - by philrabin
    I'm trying to implement the state pattern for a multi-page registration form. The data on each page will be accumulated and stored in a session object. Should validation (including service layer calls to the DB) occur on the page level or inside each state class? In other words, should the concrete implementation of IState be concerned with the validation or should it be given a fully populated and valid object? See "EmptyFormState" class below: namespace Example { public class Registrar { private readonly IState formEmptyState; private readonly IState baseInformationComplete; public RegistrarSessionData RegistrarSessionData { get; set;} public Registrar() { RegistrarSessionData = new RegistrarSessionData(); formEmptyState = new EmptyFormState(this); baseInformationComplete = new BasicInfoCompleteState(this); State = formEmptyState; } public IState State { get; set; } public void SubmitData(RegistrarSessionData data) { State.SubmitData(data); } public void ProceedToNextStep() { State.ProceedToNextStep(); } } //actual data stored in the session //to be populated by page public class RegistrarSessionData { public string FirstName { get; set; } public string LastName { get; set; } //will include values of all 4 forms } //State Interface public interface IState { void SubmitData(RegistrarSessionData data); void ProceedToNextStep(); } //Concrete implementation of IState //Beginning state - no data public class EmptyFormState : IState { private readonly Registrar registrar; public EmptyFormState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //Should Validation occur here? //Should each state object contain a validation class? (IValidator ?) //Should this throw an exception? } public void ProceedToNextStep() { registrar.State = new BasicInfoCompleteState(registrar); } } //Next step, will have 4 in total public class BasicInfoCompleteState : IState { private readonly Registrar registrar; public BasicInfoCompleteState(Registrar registrar) { this.registrar = registrar; } public void SubmitData(RegistrarSessionData data) { //etc } public void ProceedToNextStep() { //etc } } }

  • XML/C#: Read content if only if attribute is correct

    - by Zach
    Hi Guys, I have an XML file as follows, and I'm trying to read the content of the Name tag, only if the attribute of the Record tag is what I want. (continued below code) The XML file is: <?xml version="1.0" encoding="utf-8" ?> <Database> <Record Number="1"> <Name>John Doe</Name> <Position>1</Position> <HoursWorked>290</HoursWorked> <LastMonthChecked>0310</LastMonthChecked> </Record> <Record Number="2"> <Name>Jane Doe</Name> <Position>1</Position> <HoursWorked>251</HoursWorked> <LastMonthChecked>0310</LastMonthChecked> </Record> </Database> This is the C# code I have so far: public static string GetName(int EmployeeNumber) { XmlTextReader DataReader = new XmlTextReader("Database.xml"); DataReader.MoveToContent(); while (DataReader.Read()) { if (DataReader.NodeType == XmlNodeType.Element && DataReader.HasAttributes && DataReader.Name == "Record") { DataReader.MoveToAttribute(EmployeeNumber); DataReader.MoveToContent(); if (DataReader.NodeType == XmlNodeType.Element && DataReader.Name == "Name") { return DataReader.ReadContentAsString(); } } } } So for example, if 2 is passed to the function, I want it to return the string "Jane Doe". I'm new to XML parsing, so any help would be appreciated. Thanks.
