• Unable to Calculate Position within Owner-Draw Text

  - by Jonathan Wood

  I'm trying to use Visual Studio 2012 to create a Windows Forms application that can place the caret at the current position within a owner-drawn string. However, I've been unable to find a way to accurately calculate that position. I've done this successfully before in C++. I've now tried numerous methods in C#. Originally, I tried using .NET classes to determine the correct position, but then I tried accessing the Windows API directly. In some cases, I came close, but after some time I still cannot place the caret accurately. I've created a small test program and posted key parts below. I've also posted the entire project here. The exact font used is not important to me; however, my application assumes a mono-spaced font. Any help is appreciated. Form1.cs This is my main form. public partial class Form1 : Form { private string TestString; private int AveCharWidth; private int Position; public Form1() { InitializeComponent(); TestString = "123456789012345678901234567890123456789012345678901234567890"; AveCharWidth = GetFontWidth(); Position = 0; } private void Form1_Load(object sender, EventArgs e) { Font = new Font(FontFamily.GenericMonospace, 12, FontStyle.Regular, GraphicsUnit.Pixel); } protected override void OnGotFocus(EventArgs e) { Windows.CreateCaret(Handle, (IntPtr)0, 2, (int)Font.Height); Windows.ShowCaret(Handle); UpdateCaretPosition(); base.OnGotFocus(e); } protected void UpdateCaretPosition() { Windows.SetCaretPos(Padding.Left + (Position * AveCharWidth), Padding.Top); } protected override void OnLostFocus(EventArgs e) { Windows.HideCaret(Handle); Windows.DestroyCaret(); base.OnLostFocus(e); } protected override void OnPaint(PaintEventArgs e) { e.Graphics.DrawString(TestString, Font, SystemBrushes.WindowText, new PointF(Padding.Left, Padding.Top)); } protected override bool IsInputKey(Keys keyData) { switch (keyData) { case Keys.Right: case Keys.Left: return true; } return base.IsInputKey(keyData); } protected override void OnKeyDown(KeyEventArgs e) { switch (e.KeyCode) { case Keys.Left: Position = Math.Max(Position - 1, 0); UpdateCaretPosition(); break; case Keys.Right: Position = Math.Min(Position + 1, TestString.Length); UpdateCaretPosition(); break; } base.OnKeyDown(e); } protected int GetFontWidth() { int AverageCharWidth = 0; using (var graphics = this.CreateGraphics()) { try { Windows.TEXTMETRIC tm; var hdc = graphics.GetHdc(); IntPtr hFont = this.Font.ToHfont(); IntPtr hOldFont = Windows.SelectObject(hdc, hFont); var a = Windows.GetTextMetrics(hdc, out tm); var b = Windows.SelectObject(hdc, hOldFont); var c = Windows.DeleteObject(hFont); AverageCharWidth = tm.tmAveCharWidth; } catch { } finally { graphics.ReleaseHdc(); } } return AverageCharWidth; } } Windows.cs Here are my Windows API declarations. public static class Windows { [Serializable, StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)] public struct TEXTMETRIC { public int tmHeight; public int tmAscent; public int tmDescent; public int tmInternalLeading; public int tmExternalLeading; public int tmAveCharWidth; public int tmMaxCharWidth; public int tmWeight; public int tmOverhang; public int tmDigitizedAspectX; public int tmDigitizedAspectY; public short tmFirstChar; public short tmLastChar; public short tmDefaultChar; public short tmBreakChar; public byte tmItalic; public byte tmUnderlined; public byte tmStruckOut; public byte tmPitchAndFamily; public byte tmCharSet; } [DllImport("user32.dll")] public static extern bool CreateCaret(IntPtr hWnd, IntPtr hBitmap, int nWidth, int nHeight); [DllImport("User32.dll")] public static extern bool SetCaretPos(int x, int y); [DllImport("User32.dll")] public static extern bool DestroyCaret(); [DllImport("User32.dll")] public static extern bool ShowCaret(IntPtr hWnd); [DllImport("User32.dll")] public static extern bool HideCaret(IntPtr hWnd); [DllImport("gdi32.dll", CharSet = CharSet.Auto)] public static extern bool GetTextMetrics(IntPtr hdc, out TEXTMETRIC lptm); [DllImport("gdi32.dll")] public static extern IntPtr SelectObject(IntPtr hdc, IntPtr hgdiobj); [DllImport("GDI32.dll")] public static extern bool DeleteObject(IntPtr hObject); }

• What could cause a program to stay in "Add/Remove Programs" even after removing from registry

  - by Ryan

  Trying to manually remove an entry from Control Panel Add/Remove Programs. (custom software, not MS KB patch or windows component and not doing anyting 'funky' like trying to stop itself form being uninstalled) Followed http://support.microsoft.com/kb/314481 removing all applicable registry keys for program from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\ and even tried rebooting but still it persists. Double checked followed KB314481 and search for program name doesn't return any other matches in that part of the registry. Any ideas what would cause this or how to solve?

• Evaluate cron expression

  - by Jake A. Smith

  Is there a command line tool that will simply evaluate a cron expression and return a bool response if it is supposed to be running right now? I'm looking for something I can use as a utility in another bash script. Something like so: run_script=$(/tools/evaluate-cron-expression "02 4 * * *") if [ "$run_script" -eq "1" ] # etc etc I know, I know, I could just setup a real cron job, but I'm playing with the idea of wrapping all of my scheduled scripts inside of another script.

• How to serve 410 from Apache rather than a 404

  - by DanSingerman

  On our site, we tend to remove pages a lot where the content has expired, and we want to return http status 410 rather than 404 for requests to pages (physical files) that don't exist on our server (the entire site is made up of static files). We have tried from http://diveintomark.org/archives/2003/03/27/http_error_410_gone but that just breaks our entire site, serving a 410 for every request. We are using Apache 2.2.3

• View bound to paged collection view not updating all of the time.

  - by Thomas

  I new to silverlight and trying to make a business application using the mvvm pattern and ria services. I have a view model class that contains a PagedCollectoinView and it is set to the item source of a datagrid. When I update the PagedCollectionView the datagrid is only updated the first time then after that subsequent changes to the data to not reflect in the view until after another edit. Things seem to be delayed one edit. Below is a summarized example of my xaml and code behind. This is the code for my view model public class CustomerContactLinks : INotifyPropertyChanged { private ObservableCollection<CustomerContactLink> _CustomerContact; public ObservableCollection<CustomerContactLink> CustomerContact { get { if (_CustomerContact == null) _CustomerContact = new ObservableCollection<CustomerContactLink>(); return _CustomerContact; } set { _CustomerContact = value; } } private PagedCollectionView _CustomerContactPaged; public PagedCollectionView CustomerContactPaged { get { if (_CustomerContactPaged == null) _CustomerContactPaged = new PagedCollectionView(CustomerContact); return _CustomerContactPaged; } } private TicketSystemDataContext _ctx; public TicketSystemDataContext ctx { get { if (_ctx == null) _ctx = new TicketSystemDataContext(); return _ctx; } } public void GetAll() { ctx.Load(ctx.GetCustomerContactInfoQuery(), LoadCustomerContactsComplete, null); } private void LoadCustomerContactsComplete(LoadOperation<CustomerContactLink> lo) { foreach (var entity in lo.Entities) { CustomerContact.Add(entity as CustomerContactLink); } } #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; private void RaisePropertyChanged(string propertyName) { if (PropertyChanged != null) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } #endregion } Here is the basics of my XAML <Data:DataGrid x:Name="GridCustomers" MinHeight="100" MaxWidth="1000" IsReadOnly="True" AutoGenerateColumns="False"> <Data:DataGrid.Columns> <Data:DataGridTextColumn Header="First Name" Binding="{Binding Customer.FirstName}" Width="105" /> <Data:DataGridTextColumn Header="MI" Binding="{Binding Customer.MiddleName}" Width="35" /> <Data:DataGridTextColumn Header="Last Name" Binding="{Binding Customer.LastName}" Width="105"/> <Data:DataGridTextColumn Header="Address1" Binding="{Binding Contact.Address1}" Width="130"/> <Data:DataGridTextColumn Header="Address2" Binding="{Binding Contact.Address2}" Width="130"/> <Data:DataGridTextColumn Header="City" Binding="{Binding Contact.City}" Width="110"/> <Data:DataGridTextColumn Header="State" Binding="{Binding Contact.State}" Width="50"/> <Data:DataGridTextColumn Header="Zip" Binding="{Binding Contact.Zip}" Width="45"/> <Data:DataGridTextColumn Header="Home" Binding="{Binding Contact.PhoneHome}" Width="85"/> <Data:DataGridTextColumn Header="Cell" Binding="{Binding Contact.PhoneCell}" Width="85"/> <Data:DataGridTextColumn Header="Email" Binding="{Binding Contact.Email}" Width="118"/> </Data:DataGrid.Columns> </Data:DataGrid> <DataForm:DataForm x:Name="CustomerDetails" Header="Customer Details" AutoGenerateFields="False" AutoEdit="False" AutoCommit="False" CommandButtonsVisibility="Edit" Width="1000" Margin="0,5,0,0"> <DataForm:DataForm.EditTemplate> </DataForm:DataForm.EditTemplate> </DataForm:DataForm> And here is my code behind public Customers() { InitializeComponent(); BusyDialogIndicator.IsBusy = true; Loaded += new RoutedEventHandler(Customers_Loaded); CustomerDetails.BeginningEdit += new EventHandler(CustomerDetails_BeginningEdit); } void CustomerDetails_BeginningEdit(object sender, System.ComponentModel.CancelEventArgs e) { CustomerContacts.CustomerContactPaged.EditItem(CustomerDetails.CurrentItem); } private void Customers_Loaded(object sender, RoutedEventArgs e) { CustomerContacts = new CustomerContactLinks(); CustomerContacts.GetAll(); GridCustomers.ItemsSource = CustomerContacts.CustomerContactPaged; GridCustomerPager.Source = CustomerContacts.CustomerContactPaged; GridCustomers.SelectionChanged += new SelectionChangedEventHandler(GridCustomers_SelectionChanged); BusyDialogIndicator.IsBusy = false; } void GridCustomers_SelectionChanged(object sender, SelectionChangedEventArgs e) { CustomerDetails.CurrentItem = GridCustomers.SelectedItem as CustomerContactLink; } private void SaveChanges_Click(object sender, RoutedEventArgs e) { if (WebContext.Current.User.IsAuthenticated) { bool commited = CustomerDetails.CommitEdit(); if (commited && (!CustomerDetails.IsItemChanged && CustomerDetails.IsItemValid)) { CustomerContacts.Update(CustomerDetails.CurrentItem as CustomerContactLink); CustomerContacts.ctx.SubmitChanges(); CustomerContacts.CustomerContactPaged.CommitEdit(); CustomerContacts.CustomerContactPaged.Refresh(); (GridCustomers.ItemsSource as PagedCollectionView).Refresh(); } } }

• CMAK Custom Action to run synchronous executable

  - by Charles Gargent

  I am using the Connection Manager Administration Kit (CMAK) to create vpn connections for my users, if it is possible how do I create a custom action that launches an executable that runs synchronously? In the help file it says Only DLLs run synchronously, meaning that Connection Manager starts the action and then waits for the function to return before continuing Is there any way around this? I have seen something similar called VPN-Q which from the screen shots appear to do just that.

• How can I make Google Chrome display a plain text HTTP response, rather than downloading it in a fil

  - by ttIla

  There's a web site I visit that includes a document which is returned with content type text/plain and my version of Google Chrome used to display it in the browser window, as plain text. I like it that way. However, it has started to download the document now when I visit it, instead, meaning I have to open it with a text editor to view it. How can I make Chrome return to the old behaviour?

• Problem with jQuery and ASP.Net MVC 2

  - by robert_d

  I have a problem with jQuery, here is how my web app works Search.aspx web page which contains a form and jQuery script posts data to Search() action in Home controller after user clicks button1 button. Search.aspx: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<GLSChecker.Models.WebGLSQuery>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> Title </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2>Search</h2> <% Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <fieldset> <div class="editor-label"> <%: Html.LabelFor(model => model.Url) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Url, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Url) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.Location) %> </div> <div class="editor-field"> <%: Html.TextBoxFor(model => model.Location, new { size = "50" } ) %> <%: Html.ValidationMessageFor(model => model.Location) %> </div> <div class="editor-label"> <%: Html.LabelFor(model => model.KeywordLines) %> </div> <div class="editor-field"> <%: Html.TextAreaFor(model => model.KeywordLines, 10, 60, null)%> <%: Html.ValidationMessageFor(model => model.KeywordLines)%> </div> <p> <input id ="button1" type="submit" value="Search" /> </p> </fieldset> <% } %> <script src="../../Scripts/jquery-1.4.1.js" type="text/javascript"></script> <script type="text/javascript"> jQuery("#button1").click(function (e) { window.setInterval(refreshResult, 5000); }); function refreshResult() { jQuery("#divResult").load("/Home/Refresh"); } </script> <div id="divResult"> </div> </asp:Content> [HttpPost] public ActionResult Search(WebGLSQuery queryToCreate) { if (!ModelState.IsValid) return View("Search"); queryToCreate.Remote_Address = HttpContext.Request.ServerVariables["REMOTE_ADDR"]; Session["Result"] = null; SearchKeywordLines(queryToCreate); Thread.Sleep(15000); return View("Search"); }//Search() After button1 button is clicked the above script from Search.aspx web page runs. Search() action in controller runs for longer period of time. I simulate this in testing by putting Thread.Sleep(15000); in Search()action. 5 sec. after Submit button was pressed, the above jQuery script calls Refresh() action in Home controller. public ActionResult Refresh() { ViewData["Result"] = DateTime.Now; return PartialView(); } Refresh() renders this partial <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" % <%= ViewData["Result"] % The problem is that in Internet Explorer 8 there is only one request to /Home/Refresh; in Firefox 3.6.3 all requests to /Home/Refresh are made but nothing is displayed on the web page. Another problem with Firefox is that requests to /Home/Refresh are made every second not every 5 seconds. I noticed that after I clear Firefox cache the script works well first time button1 is pressed, but after that it doesn't work. I would be grateful for helpful suggestions.

• Mouse and touchpad move at different speeds

  - by Juan Manuel

  I have a compaq 610 running windows 7, and I use a USB mouse on it. The pointer speed is different for the mouse and the touchpad, so when I go to a meeting and take the notebook but not the mouse, the pointer moves too slow using the touchpad and I have to manually adjust it (of course when I return, I have to slow it down because the mouse would move the pointer too fast). Is there any way to fix this, or to have this setting separate for both devices?

  I'm running Ubuntu Squeeze and on one of the partitions df is showing the Total size as 335G: Filesystem Size Used Avail Use% Mounted on /dev/sdb 335G 225G 94G 71% /mnt However in the past it was showing as 360GB (which is the actual size): fdisk -l /dev/sdb Disk /dev/sdb: 365.0 GB, 365041287168 bytes lsof +L1 does not return anything (and anyway if this would be the case the Total space should not be affected.) On this partition I'm writing (and deleting) a lot of files and this happened before in the past, but problem solved by itself.

• Does AWS resolve same-datacenter hostnames to 10.* addresses for different customer accounts?

  - by Scott Ritchie

  If I bring up two Amazon EC2 instances and run nslookup on one for the other's hostname, amazon will return a 10.* address. This is routable within amazon, and works just fine. But does this work between different accounts? If I use one of my nodes to nslookup a hostname belonging to another customer (but still in the same datacenter) will it resolve as a 10.* address or will it give the standard public IP?

• Issue in implementing a stateless server Of a facebook application.

  - by Fahim Akhter

  I am trying to implement a stateless server. I'm using LAMP with Php but when I connect to the facebook server using facebook connect. Wouldn't it return a facebook session to me which my server will mantain. Does that remove the whole point of being stateless? Basically I want to have multiple application servers and a dumb load balancer which just sees the number of people connected to the server not who is connected to a server.

• Data table columns become out of order after changing data source.

  - by Scott Chamberlain

  This is kind of a oddball problem so I will try to describe the best that I can. I have a DataGridView that shows a list of contracts and various pieces of information about them. There are three view modes: Contract Approval, Pre-Production, and Production. Each mode has it's own set of columns that need to be displayed. What I have been doing is I have three radio buttons one for each contract style. all of them fire their check changed on this function private void rbContracts_CheckedChanged(object sender, EventArgs e) { dgvContracts.Columns.Clear();

I choose another view, everything is ok. But when I click on the first view the columns are out of order (it is like they are in reverse order but it is not exactly the same). this happens only to the first page you click on, the other two are fine. You can click off and click back on as many times as you want after those initial steps, The first list you selected at the start will be out of order the other two will be correct.

• Bandwidth Limit Php Not working

  Hey How are you doing guys, i am trying to limit bandwidth per users not by ipaddress for some reason my code doesnt work i need some help, what i am trying to do is to limit the download of the user that they would only have 10Gb per day to download however it seems to me that my buffer is not working when i use multiple connections it doesnt work, but when i use one connect it works 80% here is my code can you debug the error for me thanks. /** * @author saxtor if you can improve this code email me [email protected] * @copyright 2010 */ /** * CREATE TABLE IF NOT EXISTS `max_traffic` ( `id` int(255) NOT NULL AUTO_INCREMENT, `limit` int(255) NOT NULL, PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=0 ; */ //SQL Connection [this is hackable for testing] date_default_timezone_set("America/Guyana"); mysql_connect("localhost", "root", "") or die(mysql_error()); mysql_select_db("Quota") or die(mysql_error()); function quota($id) { $result = mysql_query("SELECT `limit` FROM max_traffic WHERE id='$id' ") or die(error_log(mysql_error()));; $row = mysql_fetch_array($result); return $row[0]; } function update_quota($id,$value) { $result = mysql_query("UPDATE `max_traffic` SET `limit`='$value' WHERE id='$id'") or die(mysql_error()); return $value; } if ( quota(1) != 0) $limit = quota(1); else $limit = 0; $multipart = false; //was a part of the file requested?

• HLSL/XNA Ambient light texture mixed up with multi pass lighting

  - by Manu-EPITA

  I've been having some troubles lately with lighting. I have found a source on google which is working pretty good on the example. However, when I try to implement it to my current project, I am getting some very weird bugs. The main one is that my textures are "mixed up" when I only activate the ambient light, which means that a model gets the texture of another one . I am using the same effect for every meshes of my models. I guess this could be the problem, but I don't really know how to "reset" an effect for a new model. Is it possible? Here is my shader: float4x4 WVP; float4x4 WVP; float3x3 World; float3 Ke; float3 Ka; float3 Kd; float3 Ks; float specularPower; float3 globalAmbient; float3 lightColor; float3 eyePosition; float3 lightDirection; float3 lightPosition; float spotPower; texture2D Texture; sampler2D texSampler = sampler_state { Texture = <Texture>; MinFilter = anisotropic; MagFilter = anisotropic; MipFilter = linear; MaxAnisotropy = 16; }; struct VertexShaderInput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 Normal : NORMAL0; }; struct VertexShaderOutput { float4 Position : POSITION0; float2 Texture : TEXCOORD0; float3 PositionO: TEXCOORD1; float3 Normal : NORMAL0; }; VertexShaderOutput VertexShaderFunction(VertexShaderInput input) { VertexShaderOutput output; output.Position = mul(input.Position, WVP); output.Normal = input.Normal; output.PositionO = input.Position.xyz; output.Texture = input.Texture; return output; } float4 PSAmbient(VertexShaderOutput input) : COLOR0 { return float4(Ka*globalAmbient + Ke,1) * tex2D(texSampler,input.Texture); } float4 PSDirectionalLight(VertexShaderOutput input) : COLOR0 { //Difuze float3 L = normalize(-lightDirection); float diffuseLight = max(dot(input.Normal,L), 0); float3 diffuse = Kd*lightColor*diffuseLight; //Specular float3 V = normalize(eyePosition - input.PositionO); float3 H = normalize(L + V); float specularLight = pow(max(dot(input.Normal,H),0),specularPower); if(diffuseLight<=0) specularLight=0; float3 specular = Ks * lightColor * specularLight; //sum all light components float3 light = diffuse + specular; return float4(light,1) * tex2D(texSampler,input.Texture); } technique MultiPassLight { pass Ambient { VertexShader = compile vs_3_0 VertexShaderFunction(); PixelShader = compile ps_3_0 PSAmbient(); } pass Directional { PixelShader = compile ps_3_0 PSDirectionalLight(); } } And here is how I actually apply my effects: public void ApplyLights(ModelMesh mesh, Matrix world, Texture2D modelTexture, Camera camera, Effect effect, GraphicsDevice graphicsDevice) { graphicsDevice.BlendState = BlendState.Opaque; effect.CurrentTechnique.Passes["Ambient"].Apply(); foreach (ModelMeshPart part in mesh.MeshParts) { graphicsDevice.SetVertexBuffer(part.VertexBuffer); graphicsDevice.Indices = part.IndexBuffer; // Texturing graphicsDevice.BlendState = BlendState.AlphaBlend; if (modelTexture != null) { effect.Parameters["Texture"].SetValue( modelTexture ); } graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); // Applying our shader to all the mesh parts effect.Parameters["WVP"].SetValue( world * camera.View * camera.Projection ); effect.Parameters["World"].SetValue(world); effect.Parameters["eyePosition"].SetValue( camera.Position ); graphicsDevice.BlendState = BlendState.Additive; // Drawing lights foreach (DirectionalLight light in DirectionalLights) { effect.Parameters["lightColor"].SetValue(light.Color.ToVector3()); effect.Parameters["lightDirection"].SetValue(light.Direction); // Applying changes and drawing them effect.CurrentTechnique.Passes["Directional"].Apply(); graphicsDevice.DrawIndexedPrimitives( PrimitiveType.TriangleList, part.VertexOffset, 0, part.NumVertices, part.StartIndex, part.PrimitiveCount ); } } I am also applying this when loading the effect: effect.Parameters["lightColor"].SetValue(Color.White.ToVector3()); effect.Parameters["globalAmbient"].SetValue(Color.White.ToVector3()); effect.Parameters["Ke"].SetValue(0.0f); effect.Parameters["Ka"].SetValue(0.01f); effect.Parameters["Kd"].SetValue(1.0f); effect.Parameters["Ks"].SetValue(0.3f); effect.Parameters["specularPower"].SetValue(100); Thank you very much UPDATE: I tried to load an effect for each model when drawing, but it doesn't seem to have changed anything. I suppose it is because XNA detects that the effect has already been loaded before and doesn't want to load a new one. Any idea why?

• Firefox password autocomplete

  - by mck89

  Hi, i have a problem with Firefox autocomplete in login forms. When i enter a password and a username for the first time it asks me if i want to remember them, i click on "remember" and it saves the data, but when i log out and then return to the login page it shows me nothing. The password is autocompleted only after i enter the username. Is there a way to do the autocomplete immediately like in any other browser?

• How to configure my local server to send email.

  - by George Edison

  The title is a bit misleading... what I want to do is a little complicated: I want to set up my server (running Ubuntu 10.04 Desktop) to send email using PHP's mail() function. I tried just using it, but the messages don't go anywhere and the return value of mail() is not FALSE, so I really don't know what's going on. Any advice/ideas for configuring this?

• CoreData: Same predicate (IN) returns different fetched results after a Save operation

  - by Jason Lee

  I have code below: NSArray *existedTasks = [[TaskBizDB sharedInstance] fetchTasksWatchedByMeOfProject:projectId]; [context save:&error]; existedTasks = [[TaskBizDB sharedInstance] fetchTasksWatchedByMeOfProject:projectId]; NSArray *allTasks = [[TaskBizDB sharedInstance] fetchTasksOfProject:projectId]; First line returns two objects; Second line save the context; Third line returns just one object, which is contained in the 'two objects' above; And the last line returns 6 objects, containing the 'two objects' returned at the first line. The fetch interface works like below: WXModel *model = [WXModel modelWithEntity:NSStringFromClass([WQPKTeamTask class])]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(%@ IN personWatchers) AND (projectId == %d)", currentLoginUser, projectId]; [model setPredicate:predicate]; NSArray *fetchedTasks = [model fetch]; if (fetchedTasks.count == 0) return nil; return fetchedTasks; What confused me is that, with the same fetch request, why return different results just after a save? Here comes more detail: The 'two objects' returned at the first line are: <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } <WQPKTeamTask: 0xf3f6130> (entity: WQPKTeamTask; id: 0xf3cb8d0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p11> ; data: { projectId = 372004; taskId = 340006; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } And the only one object returned at third line is: <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); } Printing description of allTasks: <_PFArray 0xf30b9a0>( <WQPKTeamTask: 0xf3ab9d0> (entity: WQPKTeamTask; id: 0xf3cda40 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p6> ; data: <fault>), <WQPKTeamTask: 0xf315720> (entity: WQPKTeamTask; id: 0xf3c23a0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p7> ; data: <fault>), <WQPKTeamTask: 0xf3a1ed0> (entity: WQPKTeamTask; id: 0xf3cda30 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p8> ; data: <fault>), <WQPKTeamTask: 0x1b92fcc0> (entity: WQPKTeamTask; id: 0x1b9300f0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p9> ; data: { projectId = 372004; taskId = 338001; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); }), <WQPKTeamTask: 0xf325e50> (entity: WQPKTeamTask; id: 0xf343820 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p10> ; data: <fault>), <WQPKTeamTask: 0xf3f6130> (entity: WQPKTeamTask; id: 0xf3cb8d0 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WQPKTeamTask/p11> ; data: { projectId = 372004; taskId = 340006; personWatchers = ( "0xf0bf440 <x-coredata://CFFD3F8B-E613-4DE8-85AA-4D6DD08E88C5/WWPerson/p1>" ); }) ) UPDATE 1 If I call the same interface fetchTasksWatchedByMeOfProject: in: #pragma mark - NSFetchedResultsController Delegate - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { I will get 'two objects' as well. UPDATE 2 I've tried: NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(ANY personWatchers == %@) AND (projectId == %d)", currentLoginUser, projectId]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(ANY personWatchers.personId == %@) AND (projectId == %d)", currentLoginUserId, projectId]; Still the same result. UPDATE 3 I've checked the save:&error, error is nil.

• jQuery not refreshing tabs content in IE

  - by iddimu

  Hi all! I have a page that is using jQuery tabs. Within one of my tabs I have a div that contains a form (initially hidden) that I want to use to add content to the tab. What I have works perfectly in Chrome, Firefox, and Safari. But, in IE 7 the tab will not refresh. The post works and the data gets added to the database, but it simply will not show the new content after submitting it. I don't think it matters - but, just for information I am using the Codeigniter PHP framework as well. Here is my javascript: <script type="text/javascript"> $(document).ready(function(){ // initialize the addChild form as hidden until user requests it open $('#addChild').hide(); // open the form $('#openDialog').click( function(){ $('#addChild').slideToggle(); return false; }); // close the form $('#closeDialog').click( function(){ $('#addChild').slideToggle(); return false; }); // submit the form $('#frmAddChild').submit( function(){ $('#addChild').slideToggle(); $.ajax({ url: '/children/add', type: 'POST', data: $('#frmAddChild').serialize() //cache: false }); //reload the children tab $('#tabs').tabs('load',3); return false; }); }); </script> And, here is my PHP/HTML: <?php // initialize the elements of the form $frmAddChild = array( 'name' => 'frmAddChild', 'id' => 'frmAddChild', 'method' => 'post' ); $child_name = array( 'name' => 'child_name', 'id' => 'child_name', ); $child_dob = array( 'name' => 'child_dob', 'id' => 'child_dob' ); $btnOpenDialog = array( 'name' => 'openDialog', 'id' => 'openDialog', 'value' => 'true', 'content' => 'Add Child' ); $btnCloseDialog = array( 'name' => 'closeDialog', 'id' => 'closeDialog', 'value' => 'true', 'content' => 'Cancel' ); // button that shows the drop down to add echo form_button($btnOpenDialog); ?> <div id="addChild" title="Add Child"> <?php echo form_open('children/add/',$frmAddChild); ?> <table> <tr> <td> <?php echo form_label('Child\'s Name', 'child_name'); ?>: </td> <td> <?php echo form_input($child_name); ?> </td> </tr> <tr> <td> <?php echo form_label('Date of Birth','child_dob'); ?>: </td> <td> <?php echo form_input($child_dob); ?> </td> </tr> <tr> <td colspan="2" align="right"> <?php echo form_submit('submit', 'Add'); ?> <?php echo form_button($btnCloseDialog); ?> </td> </tr> </table> <?php echo form_close(); ?> </div> Does anyone have any ideas how I can get this working correctly in IE? Also, if anyone has any comments about how I have things structured, please let me know. I'm new to Codeigniter and I am by no means a javascript or jQuery expert. Thanks for your help!
