• PHP / javascript live chat using too much bandwidth

  - by David

  So I am learning about javascript, so I am making a live chat system with PHP and javascript. I have it so the javascript refreshes the log (each message gets logged in a file on the server), and it refreshes every second. Im using firebug to monitor the resource usage, and I see under the net tab each times its updated, and the bytes add up really fast. I know I can change it to update less, but is there a way that when a user on the other end I'm talking to, when the send a message, it gets sent to the server, then an alert gets sent to me saying that the chatlog needs to update somehow. That way it only updates when the log is updated. let me know, thanks

• Webinvoke to POST JSON with ajax call

  - by G-Man

  This is my first time that I an using WCF Service with Knockout. I want to POST an entire view model as a JSON object with an ajax call. This is the error message that I get: Endpoints using 'UriTemplate' cannot be used with 'System.ServiceModel.Description.WebScriptEnablingBehavior' I have noticed that some developers send each value as a parameter which I feel is unnecessary especially if you work with a big object. This is my WCF method: [OperationContract] [WebInvoke(UriTemplate = "AddNewEvent?newEvent", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)] public bool AddNewEvent(Models.DAL_CRMEvents newEvent) { Entities.CRMEntities dbCRM = new Entities.CRMEntities(); //Models.CRMEvents crmEvent = new Models.CRMEvents(); Entities.Event crmEvent = new Entities.Event(); crmEvent.EventDateCreated = Convert.ToDateTime(newEvent.DateCreated); crmEvent.EventActive = true; crmEvent.EventDescription = newEvent.Description; crmEvent.EventDate = Convert.ToDateTime(newEvent.Date); crmEvent.EventTimeStart = TimeSpan.Parse(newEvent.TimeStart); crmEvent.EventTimeEnd = TimeSpan.Parse(newEvent.TimeEnd); crmEvent.EventAllDay = newEvent.AllDay; dbCRM.AddToEvent(crmEvent); return true; } This is my ajax function function SaveEvent (data) { var s = { newEvent: ko.mapping.toJS(data) } alert(data.AllDay()); $.ajax({ type: "POST", url: "../Services/CRMDataService.svc/AddNewEvent", data: JSON.stringify(s), contentType: "application/json; charset=utf-8", dataType: "JSON", success: function (result) { alert(result); }, error: function (jqXHR, textStatus, errorThrown) { if (textStatus == "error" && errorThrown != "") { var n = noty({ text: errorThrown, type: 'warning', dismissQueue: false, modal: true, layout: 'center', theme: 'defaults', callback: { } }) } } }) }

• Mercurial auto update problem.

  - by Ezequiel

  We are starting to use Mercurial for source control. We have configured the HGRC configuration file to do an auto update after we push to the "central" repository. With some PCs we get this error msg: warning: changegroup hook exited with status -1 HGRC looks like this: [ui] username=ADMIN verbose=true [hooks] changegroup = hg update >&2 Later we perform the update manually and everything works right.

• Update Multiple Tables at a Time - SQL Server/T-SQL

  - by peace

  I have two tables, Customer and CustomerPhone. Single record in Customer can have multiple CustomerPhone records. As you see in the image below, Phone and Fax resides in CustomerPhone table whereas the rest of the fields resides in Customer table. If user want to edits a customer record, obviously i will have to update the record in Customer table and at least two records from CustomerPhone (Phone and Fax). I could write two update statements, one Update customerPhone and the second update Customer table. Is there a better solution?

• Dropdown list bound to object data source - how to update on a button click

  - by Jen

  This is probably something really stupidly simple.. I have a drop down list bound to an object data source. I have set AppendDataBoundItems to true so that I can have an initial select. <asp:DropDownList ID="Accommodations1" runat="server" AutoPostBack="true" DataTextField="AccommodationTypeDescription" DataValueField="Id" OnDataBound="Accommodations1_DataBound" onSelectedIndexChanged="Accommodations1_SelectedIndexChanged" Width="200px" DataSourceID="AccommodationDs" AppendDataBoundItems="true"> <asp:ListItem Text="Select" Value=""></asp:ListItem> </asp:DropDownList> <asp:ObjectDataSource ID="AccommodationDs" runat="server" OldValuesParameterFormatString="original_{0}" SelectMethod="ListByPropertyId" TypeName="PropertyAccommodationController"> <SelectParameters> <asp:Parameter Name="PropertyId" Type="Int32" /> </SelectParameters> </asp:ObjectDataSource> I have a button which adds an accommodaton - so after that happens I need the dropdown list to update to include the new accommodation. So I've tried calling databind on the dropdownlist, and databind on the datasource - and nothing is making this dropdown list update. eg. PropertyAccommodations1.DataBind(); Could someone please let me know what I'm doing wrong. Originally I thought it was due to an update panel issue.. but I've removed the update panel and it still doesn't work (and checked the master page doesn't include an update panel). Thanks!!

• WCF REST Starter Kit not filling base class members on POST

  - by HJG

  I have a WCF REST Starter Kit service. The type handled by the service is a subclass of a base class. For POST requests, the base class members are not correctly populated. The class hierarchy looks like this: [DataContract] public class BaseTreeItem { [DataMember] public String Id { get; set; } [DataMember] public String Description { get; set; } } [DataContract] public class Discipline : BaseTreeItem { ... } The service definition looks like: [WebHelp(Comment = "Retrieve a Discipline")] [WebGet(UriTemplate = "discipline?id={id}")] [OperationContract] public Discipline getDiscipline(String id) { ... } [WebHelp(Comment = "Create/Update/Delete a Discipline")] [OperationContract] [WebInvoke(Method = "POST", UriTemplate = "discipline")] public WCF_Result DisciplineMaintenance(Discipline discipline) { ... } Problem: While the GET works fine (returns the base class Id and Description), the POST does not populate Id and Description even though the XML contains the fields. Sample XML: <?xml version="1.0" encoding="utf-8"?> <Discipline xmlns="http://schemas.datacontract.org/2004/07/xxx.yyy.zzz"> <DeleteFlag>7</DeleteFlag> <Description>2</Description> <Id>5</Id> <DisciplineName>1</DisciplineName> <DisciplineOwnerId>4</DisciplineOwnerId> <DisciplineOwnerLoginName>3</DisciplineOwnerLoginName> </Discipline> Thanks for any assistance.

• Using Enum in Hibernate causes select followed by an update statement

  - by Leonardo

  Hi all, I have a mapped entity wich has an enum property. By loking at log file, whenever I run a select statement on such entity, the result is an immediately following update. For example if my result set contains 100 records, then I have: [INFO org... select...] [INFO org... update... where id=?] [INFO org... update... where id=?] .... repeated 100 times If I mark the property as update=false the problem disappear. The enum is assigned trough an enum converter class, which I copied from a well known book. So I don't know if I just copy and paste the code. Here it is how is declared on hbm file. <typedef class="mypackage.HbnEnumConverter" name="the_type"> <param name="enumClassname">mypackage.TheType</param> </typedef> Can you point out a direction to investigate this ? Beside, what are the consequences of having update=false on hibernate field ? thanks

• how to POST two strings?

  - by Garrith

  Im trying to create a POST method for my AddTagtoGroup which looks like this (altho still confused as string group never seems to be used): List<Group> Groups = new List<Group>(); List<Tag> tags = new List<Tag>(); public void AddTagtoGroup(string group, string tag) { var result = Groups.Where(n => String.Equals(n.GroupName, tag)).FirstOrDefault(); if (result != null) { result.Tags.Add(new Tag() { TagName = tag }); } } My data contracts looks like this: [DataContract(Name = "Group")] public class Group { public Group() // not sure if this has to have a datamember { Tags = new List<Tag>(); } [DataMember(Name = "GroupName")] public string GroupName { get; set; } public List<Tag> Tags { get; set; } // datamember or not? } [DataContract(Name = "Tag")] public class Tag { [DataMember(Name = "TagName")] public string TagName { get; set; } } And my post method looks like this but im unsure what to put in the uri template?

• Symbols (pdb) for native dll are not loaded due to post build step

  - by sean e

  I have a native release dll that is built with symbols. There is a post build step that modifies the dll. The post build step does some compression and probably appends some data. The pdb file is still valid however neither WinDbg nor Visual Studio 2008 will load the symbols for the dll after the post build step. What bits in either the pdb file or the dll do we need to modify to get either WinDbg or Visual Studio to load the symbols when it loads a dump in which our release dll is referenced? Is it filesize that matters? A checksum or hash? A timestamp? Modify the dump? or modify the pdb? modify the dll before it is shipped? (We know the pdb is valid because we are able to use it to manually get symbol names for addresses in dump callstacks that reference the released dll. It's just a total pain in the *ss do it by hand for every address in a callstack in all the threads.)

• MySQL thousands of updates, slowing down.

  - by noryb009

  I need to run a PHP loop for a total of 100, 000 times (about 10, 000 each script-run), and each loop has about 5 MySQL UPDATES to it. When I run the loop 50 times, it takes 3 sec. When I run the loop 1000 times, it takes about 1300 sec. As you can see, MySQL is slowing down ALOT with more UPDATEs. This is an example update: mysql_query("UPDATE table SET `row1`=`row1` +1 WHERE `UniqueValue`='5'"); This is generated randomly from PHP, but I can store it in a variable and run it every n loops. Is there any way to either make MySQL and PHP run at a consistent speed (is PHP storing hidden variables?), or split up the script so they do? Note: I am running this for a development purposes, not for production, so there will only be 1 computer accessing the data.

• Efficient update of SQLite table with many records

  - by blackrim

  I am trying to use sqlite (sqlite3) for a project to store hundreds of thousands of records (would like sqlite so users of the program don't have to run a [my]sql server). I have to update hundreds of thousands of records sometimes to enter left right values (they are hierarchical), but have found the standard update table set left_value = 4, right_value = 5 where id = 12340; to be very slow. I have tried surrounding every thousand or so with begin; .... update... update table set left_value = 4, right_value = 5 where id = 12340; update... .... commit; but again, very slow. Odd, because when I populate it with a few hundred thousand (with inserts), it finishes in seconds. I am currently trying to test the speed in python (the slowness is at the command line and python) before I move it to the C++ implementation, but right now this is way to slow and I need to find a new solution unless I am doing something wrong. Thoughts? (would take open source alternative to SQLite that is portable as well)

• Pass variable by Post method from JQuery UI Autocomplete to PHP page

  - by Shahriar N Khondokar

  I have two JQuery UI autocomplete input fields. When an option is selected in the first one, the value of the selection will be used as condition for a database query that will send the source data for the second autocomplete field. My problem is how do I send the value of the first selection to the PHP page via Post method? The code so far is shown below (this code is from a tutorial which used the GET method; but I want to use Post): <script> $("input#divisions").autocomplete ({ //this is the first input source : [ { value: "81", label: "City1" }, { value: "82", label: "City2" }, { value: "83", label: "City3" } ], minLength : 0, select: function(event, ui) { $('#divisions').val(ui.item.label); return false; }, focus: function(event, ui){ $('#divisions').val(ui.item.label); return false; }, change: function(event, ui){ //the tutorial has this value sent by variables in the URL; I want the selection value sent by POST. How can I change this? c_t_v_choices = "c_t_v_choices.php?filter=" + ui.item.value; $("#c_t_v").autocomplete("option", "source", c_t_v_choices); } }).focus (function (event) { $(this).autocomplete ("search", ""); }); $("#c_t_v").autocomplete({ source: "", minLength: 2, select: function(event,ui){ //$('#city').val(ui.item.city); } }); </script> Can anyone please help? Dont hesitate to let me know if you have any questions.
