  • How a database is loaded into an application?

    - by Audel
    Hi All i need is a simple explanation on how does this function work I also attached a piece of php which I think is the one that retrieves the data from the database. Please correct me if I'm wrong Cheers. function loadDatabaseRecords () { // Mozilla/Safari if (window.XMLHttpRequest) { xmlHttpReq = new XMLHttpRequest(); } // IE else if (window.ActiveXObject) { xmlHttpReq = new ActiveXObject("Microsoft.XMLHTTP"); } alert ("To Server (Load Records):\n\najax-open-DB.php"); xmlHttpReq.open('GET', "ajax-open-DB.php", true); xmlHttpReq.onreadystatechange = loadDatabaseRecordsCallback; xmlHttpReq.send(null); } <?php $link = mysql_connect ("ipaddress", "localhost", "password"); mysql_select_db ("database1"); $query = "SELECT * from addressbook"; $result = mysql_query ($query); print "<table>"; print "<tr>"; print "<th>Firstname</th><th>Lastname</th><th>Address</th><th>Telephone</th>"; print "</tr>"; for ($i = 0; $i < mysql_num_rows ($result); $i ++) { $row = mysql_fetch_object ($result); print "<tr>"; print "<td>$row->firstname</td>"; print "<td>$row->lastname</td>"; print "<td>$row->address</td>"; print "<td>$row->telephone</td>"; print "</tr>"; } print "</table>"; mysql_close ($link); ?>

  • AJAX, same-origin Policy and working XML Requests

    - by Joern
    Hello guys, so, currently I develop Widgets for Smartphones and am going a bit more advanced into fields of data exchange between client and server applications. My problem is: For my current project I want my client file to request data from a PHP script with the help of AJAX XmlHttpRequest and the POST method: function xmlRequestNotes() { var parameter = 'p=1234'; xmlhttp = new XMLHttpRequest(); xmlhttp.open("POST", url, true); // Http Header xmlhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); xmlhttp.setRequestHeader("Content-length", parameter.length); xmlhttp.setRequestHeader("Connection", "close"); xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { json = JSON.parse(xmlhttp.responseText); // Doing Stuff with the Response } }; xmlhttp.send(parameter); } This works perfectly fine on my local server set up in XAMPP and the local Widget emulator. But if it gets onto the device (also with access to the target network) I receive the 101 Network Error. And as far as I have read, this is due to the "Same-Origin Policy" of XmlHttpRequests? My problem is to really understand that. Although the idea of this policy is clear to me, I'm a bit confused by the fact that another XmlHttpRequest for a Yahoo Weather XML Feed works fine. Now, could anyone be so helpful to enlighten me? Here is the request that returns a city name from Yahoo's weather feed: function getCityName() { xmlhttp = new XMLHttpRequest(); xmlhttp.open("GET", "http://weather.yahooapis.com/forecastrss?w=645458&u=c", true); xmlhttp.onreadystatechange = function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { xmlhttp.responseXML; var yweather = "http://xml.weather.yahoo.com/ns/rss/1.0"; alert(xmlhttp.responseXML.getElementsByTagNameNS(yweather, "location")[0].getAttribute("city")); } }; xmlhttp.send(null); } Obvious differences are the POST and GET methods for once, but seeing that the Same-Origin Policy takes effect no matter what method, I can't really make much sense of it. Why does the latter request work but not the first? I would really appreciate some help here. Greetings and a merry Christmas to you guys!

  • NSSortDescriptor for NSFetchRequestController causes crash when value of sorted attribute is changed

    - by AJ
    I have an Core Data Entity with a number of attributes, which include amount(float), categoryTotal(float) and category(string) The initial ViewController uses a FethchedResultsController to retrieve the entities, and sorts them based on the category and then the categoryTotal. No problems so far. NSManagedObjectContext *moc = [self managedObjectContext]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"Transaction" inManagedObjectContext:moc]; NSFetchRequest *request = [[[NSFetchRequest alloc] init] autorelease]; [request setEntity:entityDescription]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(dateStamp >= %@) AND (dateStamp =< %@)", startDate, endDate]; [request setPredicate:predicate]; NSSortDescriptor *sortByCategory = [[NSSortDescriptor alloc] initWithKey:@"category" ascending:sortOrder]; NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortByTotals, sortByCategory, nil]; [request setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:request managedObjectContext:managedObjectContext sectionNameKeyPath:@"category" cacheName:nil]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; On selecting a row (tableView:didSelectRowAtIndexPath), another view controller is loaded that allows editing of the amount field for the selected entity. Before returning to the first view, categoryTotal is updated by the new ‘amount’. The problem comes when returning to the first view controller, the app bombs with *Serious application error. Exception was caught during Core Data change processing: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (1) must be equal to the number of rows contained in that section before the update (1), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted). with userInfo (null) Program received signal: “EXC_BAD_ACCESS”.* This seems to be courtesy of NSSortDescriptor *sortByTotals = [[NSSortDescriptor alloc] initWithKey:@"categoryTotal" ascending:sortOrder]; If I remove this everything works as expected, but obviously without the sorting I want. I'm guessing this is to do with the sorting order changing due to categoryTotal changing (deletion / insertion) but can't find away fix this. I've verified that values are being modified correctly in the second view, so it appears down to the fetchedResultsController being confused. If the categoryAmount is changed to one that does not change the sort order, then no error is generated I'm not physically changing (ie deleting) the number of items the fetchedResultsController is returning ... the only other issue I can find that seem to generate this error Any ideas would be most welcome Thanks, AJ

  • Helping linqtosql datacontext use implicit conversion between varchar column in the database and tab

    - by user213256
    I am creating an mssql database table, "Orders", that will contain a varchar(50) field, "Value" containing a string that represents a slightly complex data type, "OrderValue". I am using a linqtosql datacontext class, which automatically types the "Value" column as a string. I gave the "OrderValue" class implicit conversion operators to and from a string, so I can easily use implicit conversion with the linqtosql classes like this: // get an order from the orders table MyDataContext db = new MyDataContext(); Order order = db.Orders(o => o.id == 1); // use implicit converstion to turn the string representation of the order // value into the complex data type. OrderValue value = order.Value; // adjust one of the fields in the complex data type value.Shipping += 10; // use implicit conversion to store the string representation of the complex // data type back in the linqtosql order object order.Value = value; // save changes db.SubmitChanges(); However, I would really like to be able to tell the linqtosql class to type this field as "OrderValue" rather than as "string". Then I would be able to avoid complex code and re-write the above as: // get an order from the orders table MyDataContext db = new MyDataContext(); Order order = db.Orders(o => o.id == 1); // The Value field is already typed as the "OrderValue" type rather than as string. // When a string value was read from the database table, it was implicity converted // to "OrderValue" type. order.Value.Shipping += 10; // save changes db.SubmitChanges(); In order to achieve this desired goal, I looked at the datacontext designer and selected the "Value" field of the "Order" table. Then, in properties, I changed "Type" to "global::MyApplication.OrderValue". The "Server Data Type" property was left as "VarChar(50) NOT NULL" The project built without errors. However, when reading from the database table, I was presented with the following error message: Could not convert from type 'System.String' to type 'MyApplication.OrderValue'. at System.Data.Linq.DBConvert.ChangeType(Object value, Type type) at Read_Order(ObjectMaterializer1 ) at System.Data.Linq.SqlClient.ObjectReaderCompiler.ObjectReader2.MoveNext() at System.Linq.Buffer1..ctor(IEnumerable1 source) at System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source) at Example.OrdersProvider.GetOrders() at ... etc From the stack trace, I believe this error is happening while reading the data from the table. When presented with converting a string to my custom data type, even though the implicit conversion operators are present, the DBConvert class gets confused and throws an error. Is there anything I can do to help it not get confused and do the implicit conversion? Thanks in advance, and apologies if I have posted in the wrong forum. cheers / Ben

  • How can I progrommatically change the target framework from 4.0 to 3.5 of a project/solution?

    - by scott
    Edit 3: After more googling it looks like you can't have the TargetFrameworkMoniker property in a .NET 3.5 application. So I guess I should be asking a different question. How do I change the Target framework from 4.0 to 3.5? Unfortunately, I can only find stuff on how to go the other way. or better yet how do i progrommatically set the target framework version of a project to something other than 4.0? Original question: I just switched to vs2010. I have an application that uses .net 3.5. It loads plugins which are generated by a different app. The plugins are using .net 4 and there for cannot be loaded. I'm using EnvDTE.Project to create a project and set the settings. I can't find what setting needs to be set for this. Edit 1: I'm generating code for about 50 solutions. When I made the switch from vs2005 to vs2010 the projects in those solutions are defaulting to .NET Framework 4.0. So I need to set the .NET Framework to 3.5 when I am generating the code for these solutions. Edit 2: After a lot of googling I found this. so then I tried this: loProp = vsGetProperty("TargetFrameworkMoniker"); vsSetValue(loProp, ".NETFramework,Version=v3.5"); the definitions for those two methods are below. as far as I can tell they do the same this as project.Properties.Item("TargetFrameworkMoniker").Value = ".NETFramework,Version=v4.0,Profile=Client"; I start getting an Property Unavailable Exception later in the code. When I remove the new lines everything works except the projects target framework is still 4.0. The code generators target framework is 3.5 so I can't use the FrameworkName class like shown in the second example in that link. here is vsGetProperty protected Property vsGetProperty(string aProperty) { bool lbDone = false; int liCount = 0; Property loProp; while (!lbDone && liCount < pMaxRetries) { try { loProp = pProject.Properties.Item(aProperty); lbDone = true; return loProp; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } return null; } and vsSetValue protected void vsSetValue(Property aProperty, string aValue) { bool lbDone = false; int liCount = 0; while (!lbDone && liCount < pMaxRetries) { try { aProperty.Value = aValue; lbDone = true; } catch (System.Runtime.InteropServices.COMException loE) { liCount++; if ((uint)loE.ErrorCode == 0x80010001) { // RPC_E_CALL_REJECTED - sleep half sec then try again System.Threading.Thread.Sleep(pDelayBetweenRetry); } } } }

  • c# event fires windows form incorrectly

    - by MikeW
    I'm trying to understand what's happening here. I have a CheckedListBox which contains some ticked and some un-ticked items. I'm trying to find a way of determining the delta in the selection of controls. I've tried some cumbersome like this - but only works part of the time, I'm sure there's a more elegant solution. A maybe related problem is the myCheckBox_ItemCheck event fires on form load - before I have a chance to perform an ItemCheck. Here's what I have so far: void clbProgs_ItemCheck(object sender, ItemCheckEventArgs e) { // i know its awful System.Windows.Forms.CheckedListBox cb = (System.Windows.Forms.CheckedListBox)sender; string sCurrent = e.CurrentValue.ToString(); int sIndex = e.Index; AbstractLink lk = (AbstractLink)cb.Items[sIndex]; List<ILink> _links = clbProgs.DataSource as List<ILink>; foreach (AbstractLink lkCurrent in _links) { if (!lkCurrent.IsActive) { if (!_groupValues.ContainsKey(lkCurrent.Linkid)) { _groupValues.Add(lkCurrent.Linkid, lkCurrent); } } } if (_groupValues.ContainsKey(lk.Linkid)) { AbstractLink lkDirty = (AbstractLink)lk.Clone(); CheckState newValue = (CheckState)e.NewValue; if (newValue == CheckState.Checked) { lkDirty.IsActive = true; } else if (newValue == CheckState.Unchecked) { lkDirty.IsActive = false; } if (_dirtyGroups.ContainsKey(lk.Linkid)) { _dirtyGroups[lk.Linkid] = lkDirty; } else { CheckState oldValue = (CheckState)e.NewValue; if (oldValue == CheckState.Checked) { lkDirty.IsActive = true; } else if (oldValue == CheckState.Unchecked) { lkDirty.IsActive = false; } _dirtyGroups.Add(lk.Linkid, lk); } } else { if (!lk.IsActive) { _dirtyGroups.Add(lk.Linkid, lk); } else { _groupValues.Add(lk.Linkid, lk); } } } Then onclick of a save button - I check whats changed before sending to database: private void btSave_Click(object sender, EventArgs e) { List<AbstractLink> originalList = new List<AbstractLink>(_groupValues.Values); List<AbstractLink> changedList = new List<AbstractLink>(_dirtyGroups.Values); IEnumerable<AbstractLink> dupes = originalList.ToArray<AbstractLink>().Intersect(changedList.ToArray<AbstractLink>()); foreach (ILink t in dupes) { MessageBox.Show("Changed"); } if (dupes.Count() == 0) { MessageBox.Show("No Change"); } } For further info. The definition of type AbstractLink uses: public bool Equals(ILink other) { if (Object.ReferenceEquals(other, null)) return false; if (Object.ReferenceEquals(this, other)) return true; return IsActive.Equals(other.IsActive) && Linkid.Equals(other.Linkid); }

  • zlib gzgets extremely slow?

    - by monkeyking
    I'm doing stuff related to parsing huge globs of textfiles, and was testing what input method to use. There is not much of a difference using c++ std::ifstreams vs c FILE, According to the documentation of zlib, it supports uncompressed files, and will read the file without decompression. I'm seeing a difference from 12 seconds using non zlib to more than 4 minutes using zlib.h This I've tested doing multiple runs, so its not a disk cache issue. Am I using zlib in some wrong way? thanks #include <zlib.h> #include <cstdio> #include <cstdlib> #include <fstream> #define LENS 1000000 size_t fg(const char *fname){ fprintf(stderr,"\t-> using fgets\n"); FILE *fp =fopen(fname,"r"); size_t nLines =0; char *buffer = new char[LENS]; while(NULL!=fgets(buffer,LENS,fp)) nLines++; fprintf(stderr,"%lu\n",nLines); return nLines; } size_t is(const char *fname){ fprintf(stderr,"\t-> using ifstream\n"); std::ifstream is(fname,std::ios::in); size_t nLines =0; char *buffer = new char[LENS]; while(is. getline(buffer,LENS)) nLines++; fprintf(stderr,"%lu\n",nLines); return nLines; } size_t iz(const char *fname){ fprintf(stderr,"\t-> using zlib\n"); gzFile fp =gzopen(fname,"r"); size_t nLines =0; char *buffer = new char[LENS]; while(0!=gzgets(fp,buffer,LENS)) nLines++; fprintf(stderr,"%lu\n",nLines); return nLines; } int main(int argc,char**argv){ if(atoi(argv[2])==0) fg(argv[1]); if(atoi(argv[2])==1) is(argv[1]); if(atoi(argv[2])==2) iz(argv[1]); }

  • 1180: Call to a possibly undefined method addEventListener

    - by Chris
    I'm going through some AS3 training, but I'm getting a weird error... I'm trying to add an event listener to the end of a motion tween in AS. I've created a tween, highlighted the frames, right clicked and copied the tween as AS and pasted it into the movie clip (I think there's a better way to do this, but I'm not sure what it is...) When I try to add the listener to the end of that code, I get the error. Here's my code. import fl.motion.AnimatorFactory; import fl.motion.MotionBase; import fl.motion.Motion; import flash.filters.*; import flash.geom.Point; import fl.motion.MotionEvent; import fl.events.*; var __motion_Enemy_3:MotionBase; if(__motion_Enemy_3 == null) { __motion_Enemy_3 = new Motion(); __motion_Enemy_3.duration = 30; // Call overrideTargetTransform to prevent the scale, skew, // or rotation values from being made relative to the target // object's original transform. // __motion_Enemy_3.overrideTargetTransform(); // The following calls to addPropertyArray assign data values // for each tweened property.

  • Spring 3 MVC - Form Failure Causes Exception When Reloading JSP

    - by jboyd
    Using Spring 3 MVC, please bear with the long code example, it's quite simple, but I want to make sure all relevant information is posted. Basically here is the use case: There is a registration page, a user can login, OR fill out a registration form. The login form is a simple HTML form, the registration form is a more complicated, Spring bound form that uses a RegistrationFormData bean. Here is the relevant code: UserController.java ... @RequestMapping(value = "/login", method = RequestMethod.GET) public String login(Model model) { model.addAttribute("registrationInfo", new ProfileAdminFormData()); return "login"; } ... @RequestMapping(value = "/login.do", method = RequestMethod.POST) public String doLogin( @RequestParam(value = "userName") String userName, @RequestParam(value = "password") String password, Model model) { logger.info("login.do : userName=" + userName + ", password=" + password); try { getUser().login(userName, password); } catch (UserNotFoundException ex) { logger.error(ex); model.addAttribute("loginError", ex.getWebViewableErrorMessage()); return "login"; } return "redirect:/"; } ... @RequestMapping(value = "/register.do") public String register( @ModelAttribute(value = "registrationInfo") ProfileAdminFormData profileAdminFormData, BindingResult result, Model model) { //todo: redirect if (new RegistrationValidator(profileAdminFormData, result).validate()) { try { User().register(profileAdminFormData); return "index"; } catch (UserException ex) { logger.error(ex); model.addAttribute("registrationErrorMessage", ex.getWebViewableErrorMessage()); return "login"; } } return "login"; } and the JSP: ... <form:form commandName="registrationInfo" action="register.do"> ... So the problem here is that when login fails I get an exception because there is no bean "registrationInfo" in the model attributes. What I need is that regardless of the path through this controller that the "registrationInfo" bean is not null, that way if login fails, as opposed to registration, that bean is still in the model. As you can see I create the registrationInfo object explicitly in my controller in the method bound to "/login", which is what I thought was going to be kind of a setup method" Something doesn't feel right about the "/login" method which sets up the page, but I needed to that in order to get the page to render at all without throwing an exception because there is no "registrationInfo" model attribute, as needed by the form in the JSP

  • disable dates using jquery inside gridview control

    - by bladerunner
    Hi there, I have a gridview which contains a textbox control. I need to show the calendar for the user to pick the date and certain dates are to be disabled using jquery. I found a post on stackoverflow that talked about how to disable certain dates. I am done with that part, except not sure how to pass the textbox control to this jquery function. Here is the code. <script type="text/javascript" language="javascript"> function pageLoad(sender, args) { var enabledDays = ['09/21/2011', '10/05/2011', '10/19/2011', '11/02/2011', '11/16/2011']; /* utility functions */ function editDays(date) { for (var i = 0; i < enabledDays.length; i++) { if (new Date(enabledDays[i]).toString() == date.toString()) { return [true]; } } return [false]; } /* create datepicker */ $(document).ready(function() { $('#<%= txtInHomeDate.ClientID %>').datepicker({ beforeShow: springDate, beforeShowDay: editDays, dateFormat: 'mm/dd/yy', buttonImage: 'images/cal.gif', buttonText: 'Choose date', firstDay: 1, buttonImageOnly: true, showOn: 'both', showAnim: 'fadeIn', onSelect: function() { $(this).trigger("onchange", null); } }); function springDate() { var defaultMin = new Date(); var defaultMax = new Date(); var Min = defaultMin; var Max = defaultMax; // make valid date from hiddenfied value format is MM/dd/yyyy dateMin = $('#<%= hfStDate.ClientID %>').val(); dateMin = new Date(dateMin); dateMax = $('#<%= hfEndDate.ClientID %>').val(); dateMax = new Date(dateMax); if (dateMin && dateMax) { Min = new Date(dateMin.getFullYear(), dateMin.getMonth(), dateMin.getDate()); Max = new Date(dateMax.getFullYear(), dateMax.getMonth(), dateMax.getDate()); } return { minDate: Min, maxDate: Max }; } }); } <.... <asp:TemplateField HeaderText="In-Home Date"> <ItemStyle HorizontalAlign="Center" /> <ItemTemplate> <asp:HiddenField ID="hfStDate" runat="server" Value="09/01/2011" /> <asp:HiddenField ID="hfEndDate" runat="server" Value="11/30/2011" /> <asp:TextBox ID="txtInHomeDate" runat="server" /> </ItemTemplate> </asp:TemplateField> Currently, it errors out since the jquery function won't find the txtInHomeDate. Could I get some help as I am pretty close to get this done? Thanks!!

  • How to do a proper search with nhibernate

    - by Denis Rosca
    Hello everyone, i'm working on a small project that is supposed to allow basic searches of the database. Currently i'm using nhibernate for the database interaction. In the database i have 2 tables: Person and Address. The Person table has a many-to-one relationship with Address. The code i've come up with for doing searches is: public IList<T> GetByParameterList(List<QueryParameter> parameterList) { if (parameterList == null) { return GetAll(); } using (ISession session = NHibernateHelper.OpenSession()) { ICriteria criteria = session.CreateCriteria<T>(); foreach (QueryParameter param in parameterList) { switch (param.Constraint) { case ConstraintType.Less: criteria.Add(Expression.Lt(param.ParameterName, param.ParameterValue)); break; case ConstraintType.More: criteria.Add(Expression.Gt(param.ParameterName, param.ParameterValue)); break; case ConstraintType.LessOrEqual: criteria.Add(Expression.Le(param.ParameterName, param.ParameterValue)); break; case ConstraintType.EqualOrMore: criteria.Add(Expression.Ge(param.ParameterName, param.ParameterValue)); break; case ConstraintType.Equals: criteria.Add(Expression.Eq(param.ParameterName, param.ParameterValue)); break; case ConstraintType.Like: criteria.Add(Expression.Like(param.ParameterName, param.ParameterValue)); break; } } try { IList<T> result = criteria.List<T>(); return result; } catch { //TODO: Implement some exception handling throw; } } } The query parameter is a helper object that i use to create criterias and send it to the dal, it looks like this: public class QueryParameter { public QueryParameter(string ParameterName, Object ParameterValue, ConstraintType constraintType) { this.ParameterName = ParameterName; this.ParameterValue = ParameterValue; this.Constraint = constraintType; } public string ParameterName { get; set; } public Object ParameterValue { get; set; } public ConstraintType Constraint { get; set; } } Now this works well if i'm doing a search like FirstName = "John" , but not when i try to give a parameter like Street = "Some Street". It seems that nhibernate is looking for a street column in the Person table but not in the Address table. Any idea on how should i change my code for so i could do a proper search? Tips? Maybe some alternatives? Disclaimer: i'm kind of a noob so please be gentle ;) Thanks, Denis.

  • How do I create/use a Fluent NHibernate convention to automap UInt32 properties to an SQL Server 200

    - by dommer
    I'm trying to use a convention to map UInt32 properties to a SQL Server 2008 database. I don't seem to be able to create a solution based on existing web sources, due to updates in the way Fluent NHibernate works - i.e. examples are out of date. I'm trying to have NHibernate generate the schema (via ExposeConfiguration). I'm happy to have NHibernate map it to anything sensible (e.g. bigint). Here's my code as it currently stands (which, when I try to expose the schema, fails due to SQL Server not supporting UInt32). Apologies for the code being a little long, but I'm not 100% sure what is relevant to the problem, so I'm erring on the side of caution. Most of it is based on this post. The error reported is: System.ArgumentException : Dialect does not support DbType.UInt32 I think I'll need a relatively comprehensive example, as I don't seem to be able to pull the pieces together into a working solution, at present. FluentConfiguration configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2008 .ConnectionString(connectionString)) .Mappings(mapping => mapping.AutoMappings.Add( AutoMap.AssemblyOf<Product>() .Conventions.Add<UInt32UserTypeConvention>())); configuration.ExposeConfiguration(x => new SchemaExport(x).Create(false, true)); namespace NHibernateTest { public class UInt32UserTypeConvention : UserTypeConvention<UInt32UserType> { // Empty. } } namespace NHibernateTest { public class UInt32UserType : IUserType { // Public properties. public bool IsMutable { get { return false; } } public Type ReturnedType { get { return typeof(UInt32); } } public SqlType[] SqlTypes { get { return new SqlType[] { SqlTypeFactory.Int32 }; } } // Public methods. public object Assemble(object cached, object owner) { return cached; } public object DeepCopy(object value) { return value; } public object Disassemble(object value) { return value; } public new bool Equals(object x, object y) { return (x != null && x.Equals(y)); } public int GetHashCode(object x) { return x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { int? i = (int?)NHibernateUtil.Int32.NullSafeGet(rs, names[0]); return (UInt32?)i; } public void NullSafeSet(IDbCommand cmd, object value, int index) { UInt32? u = (UInt32?)value; int? i = (Int32?)u; NHibernateUtil.Int32.NullSafeSet(cmd, i, index); } public object Replace(object original, object target, object owner) { return original; } } }

  • Any way to allow classes implementing IEntity and downcast to have operator == comparisons?

    - by George Mauer
    Basically here's the issue. All entities in my system are identified by their type and their id. new Customer() { Id = 1} == new Customer() {Id = 1}; new Customer() { Id = 1} != new Customer() {Id = 2}; new Customer() { Id = 1} != new Product() {Id = 1}; Pretty standard scenario. Since all Entities have an Id I define an interface for all entities. public interface IEntity { int Id { get; set;} } And to simplify creation of entities I make public abstract class BaseEntity<T> : where T : IEntity { int Id { get; set;} public static bool operator ==(BaseEntity<T> e1, BaseEntity<T> e2) { if (object.ReferenceEquals(null, e1)) return false; return e1.Equals(e2); } public static bool operator !=(BaseEntity<T> e1, BaseEntity<T> e2) { return !(e1 == e2); } } where Customer and Product are something like public class Customer : BaseEntity<Customer>, IEntity {} public class Product : BaseEntity<Product>, IEntity {} I think this is hunky dory. I think all I have to do is override Equals in each entity (if I'm super clever, I can even override it only once in the BaseEntity) and everything with work. So now I'm expanding my test coverage and find that its not quite so simple! First of all , when downcasting to IEntity and using == the BaseEntity< override is not used. So what's the solution? Is there something else I can do? If not, this is seriously annoying. Upadate It would seem that there is something wrong with my tests - or rather with comparing on generics. Check this out [Test] public void when_created_manually_non_generic() { // PASSES! var e1 = new Terminal() {Id = 1}; var e2 = new Terminal() {Id = 1}; Assert.IsTrue(e1 == e2); } [Test] public void when_created_manually_generic() { // FAILS! GenericCompare(new Terminal() { Id = 1 }, new Terminal() { Id = 1 }); } private void GenericCompare<T>(T e1, T e2) where T : class, IEntity { Assert.IsTrue(e1 == e2); } Whats going on here? This is not as big a problem as I was afraid, but is still quite annoying and a completely unintuitive way for the language to behave. Update Update Ah I get it, the generic implicitly downcasts to IEntity for some reason. I stand by this being unintuitive and potentially problematic for my Domain's consumers as they need to remember that anything happening within a generic method or class needs to be compared with Equals()

  • Feedback on Optimizing C# NET Code Block

    - by Brett Powell
    I just spent quite a few hours reading up on TCP servers and my desired protocol I was trying to implement, and finally got everything working great. I noticed the code looks like absolute bollocks (is the the correct usage? Im not a brit) and would like some feedback on optimizing it, mostly for reuse and readability. The packet formats are always int, int, int, string, string. try { BinaryReader reader = new BinaryReader(clientStream); int packetsize = reader.ReadInt32(); int requestid = reader.ReadInt32(); int serverdata = reader.ReadInt32(); Console.WriteLine("Packet Size: {0} RequestID: {1} ServerData: {2}", packetsize, requestid, serverdata); List<byte> str = new List<byte>(); byte nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // Password Sent to be Authenticated string string1 = Encoding.UTF8.GetString(str.ToArray()); str.Clear(); nextByte = reader.ReadByte(); while (nextByte != 0) { str.Add(nextByte); nextByte = reader.ReadByte(); } // NULL string string string2 = Encoding.UTF8.GetString(str.ToArray()); Console.WriteLine("String1: {0} String2: {1}", string1, string2); // Reply to Authentication Request MemoryStream stream = new MemoryStream(); BinaryWriter writer = new BinaryWriter(stream); writer.Write((int)(1)); // Packet Size writer.Write((int)(requestid)); // Mirror RequestID if Authenticated, -1 if Failed byte[] buffer = stream.ToArray(); clientStream.Write(buffer, 0, buffer.Length); clientStream.Flush(); } I am going to be dealing with other packet types as well that are formatted the same (int/int/int/str/str), but different values. I could probably create a packet class, but this is a bit outside my scope of knowledge for how to apply it to this scenario. If it makes any difference, this is the Protocol I am implementing. http://developer.valvesoftware.com/wiki/Source_RCON_Protocol

  • ActionResult - Service

    - by cem
    I bored, writing same code for service and ui. Then i tried to write a converter for simple actions. This converter, converting Service Results to MVC result, seems like good solution for me but anyway i think this gonna opposite MVC pattern. So here, I need help, what you think about algorithm - is this good or not? Thanks ServiceResult - Base: public abstract class ServiceResult { public static NoPermissionResult Permission() { return new NoPermissionResult(); } public static SuccessResult Success() { return new SuccessResult(); } public static SuccessResult<T> Success<T>(T result) { return new SuccessResult<T>(result); } protected ServiceResult(ServiceResultType serviceResultType) { _resultType = serviceResultType; } private readonly ServiceResultType _resultType; public ServiceResultType ResultType { get { return _resultType; } } } public class SuccessResult<T> : ServiceResult { public SuccessResult(T result) : base(ServiceResultType.Success) { _result = result; } private readonly T _result; public T Result { get { return _result; } } } public class SuccessResult : SuccessResult<object> { public SuccessResult() : this(null) { } public SuccessResult(object o) : base(o) { } } Service - eg. ForumService: public ServiceResult Delete(IVUser user, int id) { Forum forum = Repository.GetDelete(id); if (!Permission.CanDelete(user, forum)) { return ServiceResult.Permission(); } Repository.Delete(forum); return ServiceResult.Success(); } Controller: public class BaseController { public ActionResult GetResult(ServiceResult result) { switch (result.ResultType) { case ServiceResultType.Success: var successResult = (SuccessResult)result; return View(successResult.Result); break; case ServiceResultType.NoPermission: return View("Error"); break; default: return View(); break; } } } [HandleError] public class ForumsController : BaseController { [ValidateAntiForgeryToken] [Transaction] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Delete(int id) { ServiceResult result = ForumService.Delete(WebUser.Current, id); /* Custom result */ if (result.ResultType == ServiceResultType.Success) { TempData[ControllerEnums.GlobalViewDataProperty.PageMessage.ToString()] = "The forum was successfully deleted."; return this.RedirectToAction(ec => Index()); } /* Custom result */ /* Execute Permission result etc. */ TempData[ControllerEnums.GlobalViewDataProperty.PageMessage.ToString()] = "A problem was encountered preventing the forum from being deleted.

  • How do I find the Next Closest Date to today from a list of dates in a Plist on iOS?

    - by user1173823
    Situation: In short, I have a football schedule. I would like to use a custom cell which provides more info for only the next game date in the schedule. Issue: How do I find only the next closest game in the schedule (for iOS)? I've watched the WWDC 2013 video for "Solutions to Common Date and Time Issues" however this primarily applies to the Mac. I've searched numerous posts here and some are close but not what I need to find ONLY the next date from my list of dates in the schedule. From other posts I see where I can compare two specific dates, but this is not what I want to do. I want to find the next closest date that is equal to or after today from a list of dates. This is where I am now. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { //Populate the table from the plist NSDictionary *season = _schedContentArray[indexPath.section]; NSArray *schedule = season[@"Schedule"]; NSDictionary *game = schedule[indexPath.row]; //find the closest game date after today's date ?? NSString *gameDateStr = game[@"GameDate"]; NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init]; dateFormatter.calendar=calendar; [dateFormatter setDateFormat:@"MM/dd/yy"]; NSDate *today = [NSDate date]; NSDate *gameDate = [dateFormatter dateFromString:gameDateStr]; //NSString *nextGame = NSLog(@"game date is %@",gameDate); The NSLog returns the game dates (except for the open date): 2013-11-11 16:10:05.979 Clemson Football[24060:70b] game date is 2013-08-31 04:00:00 +0000 2013-11-11 16:10:05.982 Clemson Football[24060:70b] game date is 2013-09-07 04:00:00 +0000 2013-11-11 16:10:05.985 Clemson Football[24060:70b] game date is (null) 2013-11-11 16:10:05.987 Clemson Football[24060:70b] game date is 2013-09-19 04:00:00 +0000 2013-11-11 16:10:05.988 Clemson Football[24060:70b] game date is 2013-09-28 04:00:00 +0000 2013-11-11 16:10:05.990 Clemson Football[24060:70b] game date is 2013-10-05 04:00:00 +0000 2013-11-11 16:10:05.992 Clemson Football[24060:70b] game date is 2013-10-12 04:00:00 +0000 2013-11-11 16:10:05.993 Clemson Football[24060:70b] game date is 2013-10-19 04:00:00 +0000 2013-11-11 16:10:05.995 Clemson Football[24060:70b] game date is 2013-10-26 04:00:00 +0000 2013-11-11 16:10:05.996 Clemson Football[24060:70b] game date is 2013-11-02 04:00:00 +0000 2013-11-11 16:10:05.998 Clemson Football[24060:70b] game date is 2013-11-09 05:00:00 +0000 2013-11-11 16:10:06.000 Clemson Football[24060:70b] game date is 2013-11-14 05:00:00 +0000 2013-11-11 16:10:06.001 Clemson Football[24060:70b] game date is 2013-11-23 05:00:00 +0000 2013-11-11 16:10:06.003 Clemson Football[24060:70b] game date is 2013-11-30 05:00:00 +0000 2013-11-11 16:10:06.005 Clemson Football[24060:70b] game date is 2013-12-07 05:00:00 +0000 Thanks in advance for any assistance you can provide.

  • How to change button's image in visual c++ at run time?

    - by karikari
    After trying and error for many times, I decided to ask here. My objective is I wanted to change the feature of my IE toolbar button. The button is firstly setup by IE at IE startup using the function CRebarHandler::onSetRedraw and CRebarHandler::setButtonMenu2(). And then, I create a call from another cpp file, to call CRebarHandler::setButtonMenu2(). I intent to change just the button's image. I assigned the ID of the image correctly. But somehow it does not work. When I put other code inside this function,like a code for writing to file, it is proven work. Means, it is properly being called from the other file. But the thing is, the code for the button inside CRebarHandler::setButtonMenu2() seems does not work. Need help. Here is the code I am working on (I modify John Lister's button code): LRESULT CRebarHandler::onSetRedraw(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled){ bHandled=false; if (m_ieVer==6){ if (!m_hWndToolbar) scanForToolbarSlow(); if (m_hWndToolbar){ findButton(m_hWndToolbar); if (m_buttonID>0) setButtonMenu(); } } return S_OK; } void CRebarHandler::setButtonMenu(){ HIMAGELIST hImageList = ImageList_Create(32, 32,ILC_COLOR16 | ILC_MASK,1, 0); HINSTANCE module = _AtlBaseModule.GetResourceInstance(); TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; char psBuffer[128]; FILE *pPipe; float f = 0; pPipe = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt", "rt" ); char* p = fgets(psBuffer, 128, pPipe); std::istringstream iss(p); iss >> f; if (f > 0.9) { inf.iImage = 1; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } else { inf.iImage = 2; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } iss.clear(); f = 0; } void CRebarHandler::setButtonMenu2(){ TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; inf.iImage = 1; //green SendMessage(NULL, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); }

  • Need to know how to properly create a new object in another cpp file

    - by karikari
    I have a class. The problem now is, after a few attempt, I'm still in huge error. My problem is I don't know how to properly declare a new object for this class, inside another cpp file. I wanted to call/trigger the functions from this RebarHandler class from my other cpp file. I keep on getting problems like, 'used without being initialized', 'debug assertion failed' and so on. In the other cpp file, I include the RebarHandler.h and did like this: CRebarHandler *test=NULL; test->setButtonMenu2(); When compile, I does not give any error. But, when run time, it gives error and my IE crash. I need help. Below is the class I meant: #pragma once class CIEWindow; class CRebarHandler : public CWindowImpl<CRebarHandler>{ public: CRebarHandler(HWND hWndToolbar, CIEWindow *ieWindow); CRebarHandler(){}; ~CRebarHandler(); BEGIN_MSG_MAP(CRebarHandler) NOTIFY_CODE_HANDLER(TBN_DROPDOWN, onNotifyDropDown) NOTIFY_CODE_HANDLER(TBN_TOOLBARCHANGE, onNotifyToolbarChange) NOTIFY_CODE_HANDLER(NM_CUSTOMDRAW, onNotifyCustomDraw) NOTIFY_CODE_HANDLER(TBN_ENDADJUST, onNotifyEndAdjust) MESSAGE_HANDLER(WM_SETREDRAW, onSetRedraw) END_MSG_MAP() // message handlers LRESULT onNotifyDropDown(WPARAM wParam, LPNMHDR pNMHDR, BOOL& bHandled); LRESULT onNotifyToolbarChange(WPARAM wParam, LPNMHDR pNMHDR, BOOL& bHandled); LRESULT onNotifyCustomDraw(WPARAM wParam, LPNMHDR pNMHDR, BOOL& bHandled); LRESULT onNotifyEndAdjust(WPARAM wParam, LPNMHDR pNMHDR, BOOL& bHandled); LRESULT onSetRedraw(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled); // manage the subclassing of the IE rebar void subclass(); void unsubclass(); void handleSettings(); void setButtonMenu2(); bool findButton(HWND hWndToolbar); private: // handles to the various things HWND m_hWnd; HWND m_hWndToolbar, m_hWndRebar, m_hWndTooltip; HMENU m_hMenu; int m_buttonID; int m_ieVer; CIEWindow *m_ieWindow; // toolbar finding functions void scanForToolbarSlow(); void getRebarHWND(); void setButtonMenu(); };

  • Issue accessing class variable from thread.

    - by James
    Hello, The code below is meant to take an arraylist of product objects as an input, spun thread for each product(and add the product to the arraylist 'products'), check product image(product.imageURL) availability, remove the products without images(remove the product from the arraylist 'products'), and return an arraylist of products with image available. package com.catgen.thread; import java.util.ArrayList; import java.util.Iterator; import java.util.List; import com.catgen.Product; import com.catgen.Utils; public class ProductFilterThread extends Thread{ private Product product; private List<Product> products = new ArrayList<Product>(); public ProductFilterThread(){ } public ProductFilterThread(Product product){ this.product = product; } public synchronized void addProduct(Product product){ System.out.println("Before add: "+getProducts().size()); getProducts().add(product); System.out.println("After add: "+getProducts().size()); } public synchronized void removeProduct(Product product){ System.out.println("Before rem: "+getProducts().size()); getProducts().remove(product); System.out.println("After rem: "+getProducts().size()); } public synchronized List<Product> getProducts(){ return this.products; } public synchronized void setProducts(List<Product> products){ this.products = products; } public void run(){ boolean imageExists = Utils.fileExists(this.product.ImageURL); if(!imageExists){ System.out.println(this.product.ImageURL); removeProduct(this.product); } } public List<Product> getProductsWithImageOnly(List<Product> products){ ProductFilterThread pft = null; try{ List<ProductFilterThread> threads = new ArrayList<ProductFilterThread>(); for(Product product: products){ pft = new ProductFilterThread(product); addProduct(product); pft.start(); threads.add(pft); } Iterator<ProductFilterThread> threadsIter = threads.iterator(); while(threadsIter.hasNext()){ ProductFilterThread thread = threadsIter.next(); thread.join(); } }catch(Exception e){ e.printStackTrace(); } System.out.println("Total returned products = "+getProducts().size()); return getProducts(); } } Calling statement: displayProducts = new ProductFilterThread().getProductsWithImageOnly(displayProducts); Here, when addProduct(product) is called from within getProductsWithImageOnly(), getProducts() returns the list of products, but that's not the case(no products are returned) when the method removeProduct() is called by a thread, because of which the products without images are never removed. As a result, all the products are returned by the module whether or not the contained products have images. What can be the problem here? Thanks in advance. James.
