• C++ segmentation error when first parameter is null in comparison operator overload

  - by user1774515

  I am writing a class called Word, that handles a c string and overloads the <, , <=, = operators. word.h: friend bool operator<(const Word &a, const Word &b); word.cc: bool operator<(const Word &a, const Word &b) { if(a == NULL && b == NULL) return false; if(a == NULL) return true; if(b == NULL) return false; return a.wd < b.wd; //wd is a valid c string } main: char* temp = NULL; //EDIT: i was mistaken, temp is a char pointer Word a("blah"); //a.wd = [b,l,a,h] cout << (temp<a); i get a segmentation error before the first line of the operator< method after the last line in the main. I can correct the problem by writing cout << (a>temp); where the operator> is similarly defined and i get no errors. but my assignment requires (temp < a) to work so this is where i ask for help. EDIT: i made a mistake the first time and i said temp was of type Word, but it is actually of type char*. so i assume that the compiler converts temp to a Word using one of my constructors. i dont know which one it would use and why this would work since the first parameter is not Word. here is the constructor i think is being used to make the Word using temp: Word::Word(char* c, char* delimeters=NULL) { char *temporary = "\0"; if(c == NULL) c = temporary; check(stoppers!=NULL, "(Word(char*,char*))NULL pointer"); //exits the program if the expression is false if(strlen(c) == 0) size = DEFAULT_SIZE; //10 else size = strlen(c) + 1 + DEFAULT_SIZE; wd = new char[size]; check(wd!=NULL, "Word(char*,char*))heap overflow"); delimiters = new char[strlen(stoppers) + 1]; //EDIT: changed to [] check(delimiters!=NULL,"Word(char*,char*))heap overflow"); strcpy(wd,c); strcpy(delimiters,stoppers); count = strlen(wd); } wd is of type char* thanks for looking at this big question and trying to help. let me know if you need more code to look at

  I don't get it, I see no mistakes in this code but there is this error, please help: mysql_fetch_array() expects parameter 1 to be resource problem <?php $con = mysql_connect("localhost","root","nitoryolai123$%^"); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("school", $con); $result = mysql_query("SELECT * FROM student WHERE IDNO=".$_GET['id']); ?> <?php while ($row = mysql_fetch_array($result)) { ?> <table class="a" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#D3D3D3"> <tr> <form name="formcheck" method="get" action="updateact.php" onsubmit="return formCheck(this);"> <td> <table border="0" cellpadding="3" cellspacing="1" bgcolor=""> <tr> <td colspan="16" height="25" style="background:#5C915C; color:white; border:white 1px solid; text-align: left"><strong><font size="2">Update Students</td> <tr> <td width="30" height="35"><font size="2">*I D Number:</td> <td width="30"><input name="idnum" onkeypress="return isNumberKey(event)" type="text" maxlength="5" id='numbers'/ value="<?php echo $_GET['id']; ?>"></td> </tr> <tr> <td width="30" height="35"><font size="2">*Year:</td> <td width="30"><input name="yr" onkeypress="return isNumberKey(event)" type="text" maxlength="5" id='numbers'/ value="<?php echo $row["YEAR"]; ?>"></td> <?php } ?> I'm just trying to load the data in the forms but I don't know why that error appears.

• GKSession sendDataToAllPeers getting invalid parameter

  - by cb4

  This is my first post and I wanted to start it by thanking the many stackoverflow contributors who will never know how much they helped me out these past several days as I worked to complete my first iOS app. I am indebted to them and to this site for giving them a place to post. To 'pay off' some of that debt, I hope this will help others as I have been helped... So, my app uses the GKPeerPickerController to make a connection to a 2nd device. Once connected, the devices can send text messages to each other. The receiving peer has the message displayed in a UIAlertView. Everything was working fine. Then I decided to experiment with locations and added code to get the current location. I convert it into latitude & longitude in degrees, minutes, and seconds and put them into one NSString. I added a button to my storyboard called 'Send Location' which, when tapped, sends the location to the connected peer. This is where I ran into the problem. Both the send text and send location methods call the sendPacket method with a NSString. sendPacket converts the string to NSData and calls sendDataToAllPeers. When I learned how to capture the error, it was "Invalid parameter for - sendDataToAllPeers:withDataMode:error:". [.....pause.....] Well, this was going to be a question but in writing all this to explain the problem, the answer just dawned on me. Did a few tests and verified it now works. The issue was not in sendDataToAllPeers, it was in the conversion of the NSString (strToSend) to NSData: packet = [strToSend dataUsingEncoding:NSASCIIStringEncoding]; Specifically, it was the degree sign character (little circle, ASCII 176). NSASCIIStringEncoding only includes ASCII characters up to 127 so don't use any above that. I'm sure there was a quicker way to find the problem, but I don't know Objective-C or Xcode's debugging facility well enough yet. Whew! Several hours to discover that little tidbit. I did learn a lot, though, and that's always a good thing!

• setting value to a parameter - always saying that it is null REALLY NEED INPUT

  - by Amina

  So I have this schedule visit page with two groups. Group 1 contains a list of: Cases. Group 2 contains a list of: Parties. each group has a checkboxes next to its item for the user to select. My Issue when i select a case and/or a party and save -- then go to the edit page of the visit i just saved and only my selected case is checked and the party i selected is not checked. After debugging i realized that the partyId is not being saved properly during the create page and thus not showing as selected or saved on the edit page. I really need help on how to properly save the party selected and setting for it a value from the parameter. Here is my code of what i have for saving a case and would like to know how to properly save with party. Controller [HttpPost] [ValidateInput(false)] public ActionResult Create(VisitViewModel viewModel, Guid[] associatedCasesSelected, Guid[] selectedParties) { if (!ModelState.IsValid) { viewModel.Time = _timeEntryHelper.Value; AddLookupsToViewModel(viewModel); return View(viewModel); } var visitEntry = Mapper.Map<VisitViewModel, VisitEntry>(viewModel); ... viewModel.CasePartyIds = selectedParties; try { _visitEntryService.Create(visitEntry, associatedCasesSelected); this.FlashInfo(string.Format(Message.ConfirmationMessageCreate, Resources.Entities.Visit.EntityName)); } catch (RulesException ex) { ex.CopyTo(ModelState); } if (ModelState.IsValid) return RedirectToAction("Edit", "Case", new { caseId = viewModel.CaseId }); AddLookupsToViewModel(viewModel); return View(viewModel); } VisitEntryService public void Create(VisitEntry visitEntry,IList<Guid>caseIds) { EnsureValid(visitEntry); _visitEntryRepository.Save(visitEntry); caseIds = AddCurrentCaseToCases(visitEntry.CaseId, caseIds); foreach (var caseId in caseIds.Distinct()) { var visit = new Visit {CaseId = caseId, VisitEntryId = visitEntry.VisitEntryId}; _visitService.Create(visit); } } AddCurrentCaseToCases private static IList<Guid>AddCurrentCaseToCases(Guid caseId, IEnumerable<Guid>caseIds) { var cases = new List<Guid>(); if (caseIds != null) { cases.AddRange(caseIds); if(!caseIds.Contains(caseId)) cases.Add(caseId); } else cases.Add(caseId); return cases; } VisitService public Visit Get(Guid visitId) { return DataContext.Visits.SingleOrDefault(v => v.VisitId == visitId); } public void Save(Visit visit) { if(visit.VisitId == Guid.Empty) { visit.VisitId = Guid.NewGuid(); DataContext.Visits.InsertOnSubmit(visit); } else { var currentVisit = Get(visit.VisitId); if (currentVisit == null) throw RepositoryExceptionFactory.Create("Visit", "VisitId"); } DataContext.SubmitChanges(); } Any TIPS or IDEAS is greatly appreciated at this time :) The entitiy for the parties will be VisitEntryParty

• Unity The parameter host could not be resolved when attempting to call constructor

  - by Terrance

  When I attempt to instantiate my instance of the base class I get the error: a ResolutionFailedException with roughly the following error "The parameter host could not be resolved when attempting to call constructor" I'm currently not using an Interface for the base type and my instance of the class is inheriting the base type class. I'm new to Unity and DI so I'm thinking its something I forgot possibly. ExeConfigurationFileMap map = new ExeConfigurationFileMap(); map.ExeConfigFilename = "Unity.Config"; Configuration config = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None); UnityConfigurationSection section = (UnityConfigurationSection)config.GetSection("unity"); IUnityContainer container = new UnityContainer(); section.Containers.Default.Configure(container); //Throws exception here on this BaseCalculatorServer server = container.Resolve<BaseCalculatorServer>(); and the Unity.Config file <container> <types> <type name ="CalculatorServer" type="Calculator.Logic.BaseCalculatorServer, Calculator.Logic" mapTo="Calculator.Logic.CalculateApi, Calculator.Logic"/> </types> </container> </containers> The Base class using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.Serialization; using System.ServiceModel; using System.ServiceModel.Transactions; using Microsoft.Practices.Unity; using Calculator.Logic; namespace Calculator.Logic { public class BaseCalculatorServer : IDisposable { public BaseCalculatorServer(){} public CalculateDelegate Calculate { get; set; } public CalculationHistoryDelegate CalculationHistory { get; set; } /// <summary> /// Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. /// </summary> public void Dispose() { this.Dispose(); } } } The Implementation using System; using System.Collections.Generic; using System.Linq; using System.Text; using Calculator.Logic; using System.ServiceModel; using System.ServiceModel.Configuration; using Microsoft.Practices.Unity; namespace Calculator.Logic { public class CalculateApi:BaseCalculatorServer { public CalculateApi(ServiceHost host) { host.Open(); Console.WriteLine("Press Enter To Exit"); Console.ReadLine(); host.Close(); } public CalculateDelegate Calculate { get; set; } public CalculationHistoryDelegate CalculationHistory { get; set; } } } Yes both base class and implementation are in the same Namespace and thats something design wise that will change once I get this working. Oh and a more detailed error Resolution of the dependency failed, type = "Calculator.Logic.BaseCalculatorServer", name = "". Exception message is: The current build operation (build key Build Key[Calculator.Logic.BaseCalculatorServer, null]) failed: The value for the property "Calculate" could not be resolved.

• Actionscript multiple file upload, with parameter passing is not working

  - by Metropolis

  Hey everyone, First off, I am very bad at flash/actionscript, it is not my main programming language. I have created my own file upload flash app that has been working great for me up until this point. It uses PHP to upload the files and sends back a status message which gets displayed in a status box to the user. Now I have run into a situation where I need the HTML to pass a parameter to the Actionscript, and then to the PHP file using POST. I have tried to set this up just like adobe has it on http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_7.html without success. Here is my Actionscript code import fl.controls.TextArea; //Set filters var imageTypes:FileFilter = new FileFilter("Images (*.jpg, *.jpeg, *.gif, *.png)", "*.jpg; *.jpeg; *.gif; *.png"); var textTypes:FileFilter = new FileFilter("Documents (*.txt, *.rtf, *.pdf, *.doc)", "*.txt; *.rtf; *.pdf; *.doc"); var allTypes:Array = new Array(textTypes, imageTypes); var fileRefList:FileReferenceList = new FileReferenceList(); //Add event listeners for its various fileRefList functions below upload_buttn.addEventListener(MouseEvent.CLICK, browseBox); fileRefList.addEventListener(Event.SELECT, selectHandler); function browseBox(event:MouseEvent):void { fileRefList.browse(allTypes); } function selectHandler(event:Event):void { var phpRequest:URLRequest = new URLRequest("ajax/upload.ajax.php"); var flashVars:URLVariables = objectToURLVariables(this.root.loaderInfo); phpRequest.method = URLRequestMethod.POST; phpRequest.data = flashVars; var file:FileReference; var files:FileReferenceList = FileReferenceList(event.target); var selectedFileArray:Array = files.fileList; var listener:Object = new Object(); for (var i:uint = 0; i < selectedFileArray.length; i++) { file = FileReference(selectedFileArray[i]); try { file.addEventListener(DataEvent.UPLOAD_COMPLETE_DATA, phpResponse); file.upload(phpRequest); } catch (error:Error) { status_txt.text = file.name + " Was not uploaded correctly (" + error.message + ")"; } } } function phpResponse(event:DataEvent):void { var file:FileReference = FileReference(event.target); status_txt.htmlText += event.data; } function objectToURLVariables(parameters:Object):URLVariables { var paramsToSend:URLVariables = new URLVariables(); for(var i:String in parameters) { if(i!=null) { if(parameters[i] is Array) paramsToSend[i] = parameters[i]; else paramsToSend[i] = parameters[i].toString(); } } return paramsToSend; } The flashVars variable is the one that should contain the values from the HTML file. But whenever I run the program and output the variables in the PHP file I receive the following. //Using this command on the PHP page print_r($_POST); //I get this for output Array ( [Filename] => testfile.txt [Upload] => Submit Query ) Its almost like the parameters are getting over written or are just not working at all. Thanks for any help, Metropolis

I have a table similar to this: CREATE TABLE sales_data ( Company character(50), Contract character(50), top_revenue_sum integer, top_revenue_sales integer, last_sale timestamp) ; I'd like to create a trigger for new inserts into this table, something like this: CREATE OR REPLACE FUNCTION add_contract() RETURNS VOID DECLARE myCompany character(50), myContract character(50), BEGIN myCompany = TG_ARGV[0]; myContract = TG_ARGV[1]; IF (TG_OP = 'INSERT') THEN EXECUTE 'CREATE TABLE salesdata_' || $myCompany || '_' || $myContract || ' ( sale_amount integer, updated TIMESTAMP not null, some_data varchar(32), country varchar(2) ) ;' EXECUTE 'CREATE TRIGGER update_sales_data BEFORE INSERT OR DELETE ON salesdata_' || $myCompany || '_' || $myContract || ' FOR EACH ROW EXECUTE update_sales_data( ' || $myCompany || ',' || $myContract || ', revenue);' ; END IF; END; $add_contract$ LANGUAGE plpgsql; CREATE TRIGGER add_contract AFTER INSERT ON sales_data FOR EACH ROW EXECUTE add_contract() ; Basically, every time I insert a new row into sales_data, I want to generate a new table where the name of the table will be defined as something like "salesdata_Company_Contract" So my first question is how can I pass the Company and Contract data to the trigger so it can be passed to the add_contract() stored procedure? From my stored procedure, you'll see that I also want to update the original sales_data table whenever new data is inserted into the salesdata_Company_Contract table. This trigger will do something like this: CREATE OR REPLACE FUNCTION update_sales_data() RETURNS trigger as $update_sales_data$ DECLARE myCompany character(50) NOT NULL, myContract character(50) NOT NULL, myRevenue integer NOT NULL BEGIN myCompany = TG_ARGV[0] ; myContract = TG_ARGV[1] ; myRevenue = TG_ARGV[2] ; IF (TG_OP = 'INSERT') THEN UPDATE sales_data SET top_revenue_sales = top_revenue_sales + 1, top_revenue_sum = top_revenue_sum + $myRevenue, updated = now() WHERE Company = $myCompany AND Contract = $myContract ; ELSIF (TG_OP = 'DELETE') THEN UPDATE sales_data SET top_revenue_sales = top_revenue_sales - 1, top_revenue_sum = top_revenue_sum - $myRevenue, updated = now() WHERE Company = $myCompany AND Contract = $myContract ; END IF; END; $update_sales_data$ LANGUAGE plpgsql; This will, of course, require that I pass several parameters around within these stored procedures and triggers, and I'm not sure (a) if this is even possible, or (b) practical, or (c) best practice and we should just put this logic into our other software instead of asking the database to do this work for us. To keep our table sizes down, as we'll have hundreds of thousands of transactions per day, we've decided to partition our data using the Company and Contract strings as part of the table names themselves so they're all very small in size; file IO for us is faster and we felt we'd get better performance. Thanks for any thoughts or direction. My thinking, now that I've written all of this out, is that maybe we need to write stored procedures where we pass our insert data as parameters, and call that from our other software, and have the stored procedure do the insert into "sales_data" then create the other table. Then, have a second stored procedure to insert new data into the salesdata_Company_Contract tables, where the table name is passed to the stored proc as a parameter, and again have that stored proc do the insert, then update the main sales_data table afterward. What approach would you take?

• Using dynamic enum as type in a parameter of a method

  - by samar

  Hi Experts, What i am trying to achieve here is a bit tricky. Let me brief on a little background first before going ahead. I am aware that we can use a enum as a type to a parameter of a method. For example I can do something like this (a very basic example) namespace Test { class DefineEnums { public enum MyEnum { value1 = 0, value2 = 1 } } class UseEnums { public void UseDefinedEnums(DefineEnums.MyEnum _enum) { //Any code here. } public void Test() { // "value1" comes here with the intellisense. UseDefinedEnums(DefineEnums.MyEnum.value1); } } } What i need to do is create a dynamic Enum and use that as type in place of DefineEnums.MyEnum mentioned above. I tried the following. 1. Used a method which i got from the net to create a dynamic enum from a list of strings. And created a static class which i can use. using System; using System.Collections.Generic; using System.Reflection; using System.Reflection.Emit; namespace Test { public static class DynamicEnum { public static Enum finished; static List<string> _lst = new List<string>(); static DynamicEnum() { _lst.Add("value1"); _lst.Add("value2"); finished = CreateDynamicEnum(_lst); } public static Enum CreateDynamicEnum(List<string> _list) { // Get the current application domain for the current thread. AppDomain currentDomain = AppDomain.CurrentDomain; // Create a dynamic assembly in the current application domain, // and allow it to be executed and saved to disk. AssemblyName aName = new AssemblyName("TempAssembly"); AssemblyBuilder ab = currentDomain.DefineDynamicAssembly( aName, AssemblyBuilderAccess.RunAndSave); // Define a dynamic module in "TempAssembly" assembly. For a single- // module assembly, the module has the same name as the assembly. ModuleBuilder mb = ab.DefineDynamicModule(aName.Name, aName.Name + ".dll"); // Define a public enumeration with the name "Elevation" and an // underlying type of Integer. EnumBuilder eb = mb.DefineEnum("Elevation", TypeAttributes.Public, typeof(int)); // Define two members, "High" and "Low". //eb.DefineLiteral("Low", 0); //eb.DefineLiteral("High", 1); int i = 0; foreach (string item in _list) { eb.DefineLiteral(item, i); i++; } // Create the type and save the assembly. return (Enum)Activator.CreateInstance(eb.CreateType()); //ab.Save(aName.Name + ".dll"); } } } Tried using the class but i am unable to find the "finished" enum defined above. i.e. I am not able to do the following public static void TestDynEnum(Test.DynamicEnum.finished _finished) { // Do anything here with _finished. } I guess the post has become too long but i hope i have made it quite clear. Please help! Thanks in advance! Regards, Samar

• Calling AuditQuerySystemPolicy() (advapi32.dll) from C# returns "The parameter is incorrect"

  - by JCCyC

  The sequence is like follows: Open a policy handle with LsaOpenPolicy() (not shown) Call LsaQueryInformationPolicy() to get the number of categories; For each category: Call AuditLookupCategoryGuidFromCategoryId() to turn the enum value into a GUID; Call AuditEnumerateSubCategories() to get a list of the GUIDs of all subcategories; Call AuditQuerySystemPolicy() to get the audit policies for the subcategories. All of these work and return expected, sensible values except the last. Calling AuditQuerySystemPolicy() gets me a "The parameter is incorrect" error. I'm thinking there must be some subtle unmarshaling problem. I'm probably misinterpreting what exactly AuditEnumerateSubCategories() returns, but I'm stumped. You'll see (commented) I tried to dereference the return pointer from AuditEnumerateSubCategories() as a pointer. Doing or not doing that gives the same result.

• Spring security - Reach users ID without passing it through every controller

  - by nilsi

  I have a design issue that I don't know how to solve. I'm using Spring 3.2.4 and Spring security 3.1.4. I have a Account table in my database that looks like this: create table Account (id identity, username varchar unique, password varchar not null, firstName varchar not null, lastName varchar not null, university varchar not null, primary key (id)); Until recently my username was just only a username but I changed it to be the email address instead since many users want to login with that instead. I have a header that I include on all my pages which got a link to the users profile like this: <a href="/project/users/<%= request.getUserPrincipal().getName()%>" class="navbar-link"><strong><%= request.getUserPrincipal().getName()%></strong></a> The problem is that <%= request.getUserPrincipal().getName()%> returns the email now, I don't want to link the user's with thier emails. Instead I want to use the id every user have to link to the profile. How do I reach the users id's from every page? I have been thinking of two solutions but I'm not sure: Change the principal to contain the id as well, don't know how to do this and having problem finding good information on the topic. Add a model attribute to all my controllers that contain the whole user but this would be really ugly, like this. Account account = entityManager.find(Account.class, email); model.addAttribute("account", account); There are more way's as well and I have no clue which one is to prefer. I hope it's clear enough and thank you for any help on this. ====== Edit according to answer ======= I edited Account to implement UserDetails, it now looks like this (will fix the auto generated stuff later): @Entity @Table(name="Account") public class Account implements UserDetails { @Id private int id; private String username; private String password; private String firstName; private String lastName; @ManyToOne private University university; public Account() { } public Account(String username, String password, String firstName, String lastName, University university) { this.username = username; this.password = password; this.firstName = firstName; this.lastName = lastName; this.university = university; } public String getUsername() { return username; } public String getPassword() { return password; } public String getFirstName() { return firstName; } public String getLastName() { return lastName; } public void setUsername(String username) { this.username = username; } public void setPassword(String password) { this.password = password; } public void setFirstName(String firstName) { this.firstName = firstName; } public void setLastName(String lastName) { this.lastName = lastName; } public University getUniversity() { return university; } public void setUniversity(University university) { this.university = university; } public int getId() { return id; } public void setId(int id) { this.id = id; } @Override public Collection<? extends GrantedAuthority> getAuthorities() { // TODO Auto-generated method stub return null; } @Override public boolean isAccountNonExpired() { // TODO Auto-generated method stub return false; } @Override public boolean isAccountNonLocked() { // TODO Auto-generated method stub return false; } @Override public boolean isCredentialsNonExpired() { // TODO Auto-generated method stub return false; } @Override public boolean isEnabled() { // TODO Auto-generated method stub return true; } } I also added <%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %> To my jsp files and trying to reach the id by <sec:authentication property="principal.id" /> This gives me the following org.springframework.beans.NotReadablePropertyException: Invalid property 'principal.id' of bean class [org.springframework.security.authentication.UsernamePasswordAuthenticationToken]: Bean property 'principal.id' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter? ====== Edit 2 according to answer ======= I based my application on spring social samples and I never had to change anything until now. This are the files I think are relevant, please tell me if theres something you need to see besides this.

This is starting to be something else compared to my initial question, I should maybe start another question. Sorry for my lack of experience in this. I have to read up.

• Using Table-Valued Parameters in SQL Server

  - by Jesse

  I work with stored procedures in SQL Server pretty frequently and have often found myself with a need to pass in a list of values at run-time. Quite often this list contains a set of ids on which the stored procedure needs to operate the size and contents of which are not known at design time. In the past I’ve taken the collection of ids (which are usually integers), converted them to a string representation where each value is separated by a comma and passed that string into a VARCHAR parameter of a stored procedure. The body of the stored procedure would then need to parse that string into a table variable which could be easily consumed with set-based logic within the rest of the stored procedure. This approach works pretty well but the VARCHAR variable has always felt like an un-wanted “middle man” in this scenario. Of course, I could use a BULK INSERT operation to load the list of ids into a temporary table that the stored procedure could use, but that approach seems heavy-handed in situations where the list of values is usually going to contain only a few dozen values. Fortunately SQL Server 2008 introduced the concept of table-valued parameters which effectively eliminates the need for the clumsy middle man VARCHAR parameter. Example: Customer Transaction Summary Report Let’s say we have a report that can summarize the the transactions that we’ve conducted with customers over a period of time. The report returns a pretty simple dataset containing one row per customer with some key metrics about how much business that customer has conducted over the date range for which the report is being run. Sometimes the report is run for a single customer, sometimes it’s run for all customers, and sometimes it’s run for a handful of customers (i.e. a salesman runs it for the customers that fall into his sales territory). This report can be invoked from a website on-demand, or it can be scheduled for periodic delivery to certain users via SQL Server Reporting Services. Because the report can be created from different places and the query to generate the report is complex it’s been packed into a stored procedure that accepts three parameters: @startDate – The beginning of the date range for which the report should be run. @endDate – The end of the date range for which the report should be run. @customerIds – The customer Ids for which the report should be run. Obviously, the @startDate and @endDate parameters are DATETIME variables. The @customerIds parameter, however, needs to contain a list of the identity values (primary key) from the Customers table representing the customers that were selected for this particular run of the report. In prior versions of SQL Server we might have made this parameter a VARCHAR variable, but with SQL Server 2008 we can make it into a table-valued parameter. Defining And Using The Table Type In order to use a table-valued parameter, we first need to tell SQL Server about what the table will look like. We do this by creating a user defined type. For the purposes of this stored procedure we need a very simple type to model a table variable with a single integer column. We can create a generic type called ‘IntegerListTableType’ like this: CREATE TYPE IntegerListTableType AS TABLE (Value INT NOT NULL) Once defined, we can use this new type to define the @customerIds parameter in the signature of our stored procedure. The parameter list for the stored procedure definition might look like: 1: CREATE PROCEDURE dbo.rpt_CustomerTransactionSummary 2: @starDate datetime, 3: @endDate datetime, 4: @customerIds IntegerListTableTableType READONLY   Note the ‘READONLY’ statement following the declaration of the @customerIds parameter. SQL Server requires any table-valued parameter be marked as ‘READONLY’ and no DML (INSERT/UPDATE/DELETE) statements can be performed on a table-valued parameter within the routine in which it’s used. Aside from the DML restriction, however, you can do pretty much anything with a table-valued parameter as you could with a normal TABLE variable. With the user defined type and stored procedure defined as above, we could invoke like this: 1: DECLARE @cusomterIdList IntegerListTableType 2: INSERT @customerIdList VALUES (1) 3: INSERT @customerIdList VALUES (2) 4: INSERT @customerIdList VALUES (3) 5:  6: EXEC dbo.rpt_CustomerTransationSummary 7: @startDate = '2012-05-01', 8: @endDate = '2012-06-01' 9: @customerIds = @customerIdList   Note that we can simply declare a variable of type ‘IntegerListTableType’ just like any other normal variable and insert values into it just like a TABLE variable. We could also populate the variable with a SELECT … INTO or INSERT … SELECT statement if desired. Using The Table-Valued Parameter With ADO .NET Invoking a stored procedure with a table-valued parameter from ADO .NET is as simple as building a DataTable and passing it in as the Value of a SqlParameter. Here’s some example code for how we would construct the SqlParameter for the @customerIds parameter in our stored procedure: 1: var customerIdsParameter = new SqlParameter(); 2: customerIdParameter.Direction = ParameterDirection.Input; 3: customerIdParameter.TypeName = "IntegerListTableType"; 4: customerIdParameter.Value = selectedCustomerIds.ToIntegerListDataTable("Value");   All we’re doing here is new’ing up an instance of SqlParameter, setting the pamameters direction, specifying the name of the User Defined Type that this parameter uses, and setting its value. We’re assuming here that we have an IEnumerable<int> variable called ‘selectedCustomerIds’ containing all of the customer Ids for which the report should be run. The ‘ToIntegerListDataTable’ method is an extension method of the IEnumerable<int> type that looks like this: 1: public static DataTable ToIntegerListDataTable(this IEnumerable<int> intValues, string columnName) 2: { 3: var intergerListDataTable = new DataTable(); 4: intergerListDataTable.Columns.Add(columnName); 5: foreach(var intValue in intValues) 6: { 7: var nextRow = intergerListDataTable.NewRow(); 8: nextRow[columnName] = intValue; 9: intergerListDataTable.Rows.Add(nextRow); 10: } 11:  12: return intergerListDataTable; 13: }   Since the ‘IntegerListTableType’ has a single int column called ‘Value’, we pass that in for the ‘columnName’ parameter to the extension method. The method creates a new single-columned DataTable using the provided column name then iterates over the items in the IEnumerable<int> instance adding one row for each value. We can then use this SqlParameter instance when invoking the stored procedure just like we would use any other parameter. Advanced Functionality Using passing a list of integers into a stored procedure is a very simple usage scenario for the table-valued parameters feature, but I’ve found that it covers the majority of situations where I’ve needed to pass a collection of data for use in a query at run-time. I should note that BULK INSERT feature still makes sense for passing large amounts of data to SQL Server for processing. MSDN seems to suggest that 1000 rows of data is the tipping point where the overhead of a BULK INSERT operation can pay dividends. I should also note here that table-valued parameters can be used to deal with more complex data structures than single-columned tables of integers. A User Defined Type that backs a table-valued parameter can use things like identities and computed columns. That said, using some of these more advanced features might require the use the SqlDataRecord and SqlMetaData classes instead of a simple DataTable. Erland Sommarskog has a great article on his website that describes when and how to use these classes for table-valued parameters. What About Reporting Services? Earlier in the post I referenced the fact that our example stored procedure would be called from both a web application and a SQL Server Reporting Services report. Unfortunately, using table-valued parameters from SSRS reports can be a bit tricky and warrants its own blog post which I’ll be putting together and posting sometime in the near future.

• PHP, javascript, single quote problems with IE when passing variable from ajax post to javascript fu

  - by Mattis

  Hi! I have been trying to get this to work for a while, and I suspect there's an easy solution that I just can't find. My head feels like jelly and I would really appreciate any help. My main page.php makes a .post() to backend.php and fetches a list of cities which it echoes in the form of: <li onclick="script('$data');">$data</li> The list is fetched and put onto the page via .html(). My problem occurs when $data has a single quote in it. backend.php passes the variable just fine to page.php but when i run html() it throws a javascript error (in IE, not FF obviously); ')' is expected IE parses the single quote and messes up the script()-call. I've been trying to rebuild the echoed string in different ways, escaping the 's on the php side and/or on the javascript side - but in vain. Do I have to review the script in total? page.php $.post("backend.php", {q: ""+str+""}, function(data) { if(data.length >0) { $('#results').html(data); } backend.php while ($row = $q->fetch()) { $city = $row['City']; // $city = addslashes($row['City']); // $city = str_replace("'","&#39;",$row['City']); echo "<li onclick=\"script('$city');\">".$city."</li>"; }

• Passing Custom Headers to Ajax request on Select2

  - by Sutikshan Dubey

  We are trying to implement Ajax Remote data loading in Select2:- $scope.configPartSelect2 = { minimumInputLength: 3, ajax: { url: "/api/Part", // beforeSend: function (xhr) { xhr.setRequestHeader('Authorization-Token', http.defaults.headers.common['Authorization-Token']); }, // headers: {'Authorization-Token': http.defaults.headers.common['Authorization-Token']}, data: function (term, page) { return {isStockable: true}; }, results: function (data, page) { // parse the results into the format expected by Select2. // since we are using custom formatting functions we do not need to alter remote JSON data return { results: data }; } } }; We are using AngularJS. With each Http request we have set it's default to have our Authtoken as header. But somehow it is not working in conjunction with Select2 Ajax request. In above code, commented code are my failed attempts.

• Passing multiple parameters in an MVC Ajax.ActionLink

  - by mwright

  I am using an Ajax.ActionLink to call an Action in a Controller, nothing special there. I want to pass two parameters to the Action. Is this possible using an Ajax.ActionLink? I thought that it would just be a matter of including multiple values in the AjaxOptions: <%= Ajax.ActionLink("Link Text", "ActionName", "ControllerName", new { firstParameter = firstValueToPass, secondParameter = secondValueToPass }, new AjaxOptions{ UpdateTargetId = "updateTargetId"} )%> Is it possible to pass multiple parameters? Where is a good place to learn more about the AjaxOptions?

• CA2000 passing object reference to base constructor in C#

  - by Timothy

  I receive a warning when I run some code through Visual Studio's Code Analysis utility which I'm not sure how to resolve. Perhaps someone here has come across a similar issue, resolved it, and is willing to share their insight. I'm programming a custom-painted cell used in a DataGridView control. The code resembles: public class DataGridViewMyCustomColumn : DataGridViewColumn { public DataGridViewMyCustomColumn() : base(new DataGridViewMyCustomCell()) { } It generates the following warning: CA2000 : Microsoft.Reliability : In method 'DataGridViewMyCustomColumn.DataGridViewMyCustomColumn()' call System.IDisposable.Dispose on object 'new DataGridViewMyCustomCell()' before all references to it are out of scope. I understand it is warning me DataGridViewMyCustomCell (or a class that it inherits from) implements the IDisposable interface and the Dispose() method should be called to clean up any resources claimed by DataGridViewMyCustomCell when it is no longer. The examples I've seen on the internet suggest a using block to scope the lifetime of the object and have the system automatically dispose it, but base isn't recognized when moved into the body of the constructor so I can't write a using block around it... which I'm not sure I'd want to do anyway, since wouldn't that instruct the run time to free the object which could still be used later inside the base class? My question then, is the code okay as is? Or, how could it be refactored to resolve the warning? I don't want to suppress the warning unless it is truly appropriate to do so.

• jqGrid tableToGrid "options" parameter

  - by Jimbo

  Basics Hi all, I have see the tableToGrid method (by Peter Romianowski) defined as tableToGrid(selector, options) on the jqGrid wiki, but cannot find anywhere that has documentation of the options Does anyone know about these or where to find them? More What Im actually trying to do is encase the resulting jqGrid in a form, which will submit the checkbox values that are in a column of the table. My problem is that the tableToGrid method appears to be removing the name property from the checkbox elements and hence they are not being submitted with the form post.
