• Best way to program a call to php

  - by hairdresser-101

  I've recently posted here http://stackoverflow.com/questions/2627645/accessing-session-when-using-file-get-contents-in-php about a problem I was having and the general consensus is that I'm not doing it right... while I generally think "as long as it works..." I thought I'd get some feedback on how I could do it better... I was to send the exact same email in the exact same format from multiple different areas. When a job is entered (automatically as a part of the POST) Manually when reviewing jobs to re-assign to another installer The original script is a php page which is called using AJAX to send the work order request - this worked by simply calling a standard php page, returning the success or error message and then displaying within the calling page. Now I have tried to use the same page within the automated job entry so it accepts the job via a form, logs it and mails it. My problem is (as you can see from the original post) the function file_get_contents() is not good for this cause in the automated script... My problem is that from an AJAX call I need to do things like include the database connection initialiser, start the session and do whatever else needs to be done in a standalone page... Some or all of these are not required if it is an include so it makes the file only good for one purpose... How do I make the file good for both purposes? I guess I'm looking for recommendations for the best file layout and structure to cater for both scenarios... The current file looks like: <?php session_start(); $order_id = $_GET['order_id']; include('include/database.php'); function getLineItems($order_id) { $query = mysql_query("SELECT ...lineItems..."); //Print rows with data while($row = mysql_fetch_object($query)) { $lineItems .= '...Build Line Item String...'; } return $lineItems; } function send_email($order_id) { //Get data for current job to display $query = mysql_query("SELECT ...Job Details..."); $row = mysql_fetch_object($query); $subject = 'Work Order Request'; $email_message = '...Build Email... ...Include Job Details... '.getLineItems($order_id).' ...Finish Email...'; $headers = '...Create Email Headers...'; if (mail($row->primary_email, $subject, $email_message, $headers)) { $query = mysql_query("...log successful send..."); if (mysql_error()!="") { $message .= '...display mysqlerror()..'; } $message .= '...create success message...'; } else { $query = mysql_query("...log failed send..."); if (mysql_error()!="") { $message .= '...display mysqlerror()..'; } $message .= '...create failed message...'; } return $message; } // END send_email() function //Check supplier info $query = mysql_query("...get suppliers info attached to order_id..."); if (mysql_num_rows($query) > 0) { while($row = mysql_fetch_object($query)) { if ($row->primary_email=="") { $message .= '...no email message...'; } else if ($row->notification_email=="") { $message .= '...no notifications message...'; } else { $message .= send_email($order_id); } } } else { $message .= '...no supplier matched message...'; } print $message; ?>

• How I can add JScroll bar to NavigableImagePanel which is an Image panel with an small navigation vi

  - by Sarah Kho

  Hi, I have the following NavigableImagePanel, it is under BSD license and I found it in the web. What I want to do with this panel is as follow: I want to add a JScrollPane to it in order to show images in their full size and let the users to re-center the image using the small navigation panel. Right now, the panel resize the images to fit them in the current panel size. I want it to load the image in its real size and let users to navigate to different parts of the image using the navigation panel.

• Thread not behaving correctly

  - by ivor

  Hello, I wonder if anyone can help me to understand where I could be going wrong with this code; Basically I'm working on a turorial and calling the class below from another class - and it is getting the following error; Exception in thread "Thread-1" java.lang.NullPointerException at org.newdawn.spaceinvaders.TCPChat.run(TCPChat.java:322) at java.lang.Thread.run(Unknown Source) I realise the error is beibg flagged in another class- but I have tested the other class with a small class which sets up a separate thread - and it works fine, but as soon as I try and implement a new thread in this class - it causes all sorts of problems. Am I setting up the thread correctly in this class? Basically I can set up a thread in this class, with a test loop and it's fine, but when I bring in the functionality of the rest of the game it sometimes hangs, or does not display at all. Any suggestions on where I could be going wrong would be greatly appreciated.

  Hi, I've been using this method to gain access to internet from my Android emulator emulator -http-proxy < -avd < It works but is that the best way to do it? It just doesn't feel right that I need to open the emulator from command line and can't just do it from Eclipse or something. Can't seem to find an internet option on the "AVD Manager" either.

  My setup is Spring 3 JMS, MVC + Websphere MQ + Websphere 7 <!-- this is the Message Driven POJO (MDP) --> <bean id="messageListener" class="com.SomeListener" /> <!-- and this is the message listener container --> <bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer"> <property name="connectionFactory" ref="xxxCF" /> <property name="destination" ref="someQueue" /> <property name="messageListener" ref="messageListener" /> </bean> When I start up the server, the listener seems to start correctly since it receives the messages that are on the queue as I put them.

• Column Header for a WPF TreeView

  - by nareshbhatia

  I am using the WPF TreeView to display some hierarchical information. Each item in the TreeView consists of several attributes, so I am using a Grid within my HierarchicalDataTemplate to display these attributes: <HierarchicalDataTemplate x:Key="ArtistTemplate" ItemsSource="{Binding XPath=Title}" ItemTemplate="{StaticResource TitleTemplate}"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition SharedSizeGroup="NameColumn" /> <ColumnDefinition SharedSizeGroup="GenreColumn" /> <ColumnDefinition SharedSizeGroup="BornColumn" /> <ColumnDefinition SharedSizeGroup="DiedColumn" /> </Grid.ColumnDefinitions> <TextBlock Grid.Column="0" Text="{Binding XPath=@Name}" /> <TextBlock Grid.Column="1" Text="{Binding XPath=@Genre}" /> <TextBlock Grid.Column="2" Text="{Binding XPath=@Born}" /> <TextBlock Grid.Column="3" Text="{Binding XPath=@Died}" /> </Grid> </HierarchicalDataTemplate> This displays as a nice TreeView with 4 columns - so far so good! The only additional thing I need is a header above the TreeView that displays column names. The header column widths should be synchronized with TreeViewItems and also the header styles should be customizable. What's the easiest way to do this? P.S. I found two solutions that came close: 1) A TreeListView here, but this requires me to implement a custom interface (ITreeModel) to my model. Also the approach in this solution is to start with a ListView and to implement a RowExpander manually. In my case, the TreeView is sufficiently close to what I need, so I am hoping that putting a header on it should be very simple. 2) A TreeListView here. This one indeed starts with a TreeView, but I can't figure out how to customize the header. I suspect that I have to customize the GridViewHeaderRowPresenter in the generic.xaml, but this element does not seem to have its own ControlTemplate.

• bind a WPF datagrid to a datatable

  - by Jim Thomas

  I have used the marvelous example posted at: http://www.codeproject.com/KB/WPF/WPFDataGridExamples.aspx to bind a WPF datagrid to a datatable. The source code below compiles fine; it even runs and displays the contents of the InfoWork datatable in the wpf datagrid. Hooray! But the WPF page with the datagrid will not display in the designer. I get an incomprehensible error instead on my design page which is shown at the end of this posting. I assume the designer is having some difficulty instantiating the dataview for display in the grid. How can I fix that? XAML Code: xmlns:local="clr-namespace:InfoSeeker" <Window.Resources> <ObjectDataProvider x:Key="InfoWorkData" ObjectType="{x:Type local:InfoWorkData}" /> <ObjectDataProvider x:Key="InfoWork" ObjectInstance="{StaticResource InfoWorkData}" MethodName="GetInfoWork" /> </Window.Resources> <my:DataGrid DataContext="{Binding Source={StaticResource InfoWork}}" AutoGenerateColumns="True" ItemsSource="{Binding}" Name="dataGrid1" xmlns:my="http://schemas.microsoft.com/wpf/2008/toolkit" /> C# Code: namespace InfoSeeker { public class InfoWorkData { private InfoTableAdapters.InfoWorkTableAdapter infoAdapter; private Info infoDS; public InfoWorkData() { infoDS = new Info(); infoAdapter = new InfoTableAdapters.InfoWorkTableAdapter(); infoAdapter.Fill(infoDS.InfoWork); } public DataView GetInfoWork() { return infoDS.InfoWork.DefaultView; } } } Error shown in place of the designer page which has the grid on it: An unhandled exception has occurred: Type 'MS.Internal.Permissions.UserInitiatedNavigationPermission' in Assembly 'PresentationFramework, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable. at System.Runtime.Serialization.FormatterServices.InternalGetSerializableMembers(RuntimeType type) at System.Runtime.Serialization.FormatterServices.GetSerializableMembers(Type type, StreamingContext context) at System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.InitMemberInfo() at System.Runtime.Serialization.Formatters.Binary.WriteObjectInfo.InitSerialize(Object obj, ISurrogateSelector surrogateSelector, StreamingContext context, SerObjectInfoInit serObjectInfoInit, IFormatterConverter converter, ObjectWriter objectWriter) ...At:Ms.Internal.Designer.DesignerPane.LoadDesignerView()

• Spring Security - Interactive login attempt was unsuccessful

  - by Taylor L

  I've been trying to track down why Spring Security isn't creating the SPRING_SECURITY_REMEMBER_ME_COOKIE so I turned on logging for org.springframework.security.web.authentication.rememberme. At first glance, the logs make it seem like the login is failing but the login is actually successful in the sense that if I navigate to a page that requires authentication I am not redirected back to the login page. However, the logs appear to be saying the login credentials are invalid. Any ideas as to what is going on?

• How to use multiple DisplayName attribute using Entity Framework and ASP.Net Mvc 2

  - by Picflight

  Depending on where I use my Class, I want to be able to show a different DisplayName. I have the following class: [MetadataType(typeof(PortalMetaData))] [System.Web.Mvc.Bind(Exclude = "PortalId")] public partial class Portal { public Portal() { this.Created = DateTime.Now; } } public class PortalMetaData { [Required(ErrorMessage = "Portal name is required")] [StringLength(50, ErrorMessage = "Portal name must be under 50 characters")] public object PortalName { get; set; } [Required(ErrorMessage = "Description is required")] public object Description { get; set; } } I have a corresponding Table in the database Portal I use the Portal table with a PortalController for the Site Admin to update the records in the Portal Table. I want another user with a different Role (AsstAdmin) to be able to update this table as well. To facilitate that I am thinking of creating a separate partial class that somehow links back to the Portal Model. This would allow me to display limited Fields for update by the AsstAdmin and I can display a different name for the Field as well. How can I accomplish this task? If I add the following class which inherits from Portal than I get an exception: Unable to cast object of type 'Project1.Mvc.Models.Portal' to type 'Prpject1.Mvc.Models.Site'. [MetadataType(typeof(SiteMetaData))] public class Site : Portal { public Site() { } } public class SiteMetaData { [Required(DisplayName = "Site Description")] public object Description { get; set; } }

• WinForms ComboBox DropDown and Autocomplete window both appear

  - by Clyde

  I've got a combobox on a winforms app with this code: comboBox1.AutoCompleteMode = AutoCompleteMode.SuggestAppend; comboBox1.AutoCompleteSource = AutoCompleteSource.ListItems; DataTable t = new DataTable(); t.Columns.Add("ID", typeof(int)); t.Columns.Add("Display", typeof(string)); for (int i = 1; i < 2000; i++) { t.Rows.Add(i, i.ToString("N0")); } comboBox1.DataSource = t; comboBox1.ValueMember = "ID"; comboBox1.DisplayMember = "Display"; I then follow these steps when the window opens: Click the combobox drop down button -- this displays the list of items and selects the text in the combobox Type '5', '1' ... i.e. I'm looking to use autocomplete to search for 515, 516, etc. You'll see that the autocomplete window now appears ON TOP of the drop down list. However if I mouse over, it's the obscured drop down window behind the autocomplete window that's receiving the mouse events, including the click. So I think I'm clicking on an autocomplete item but actually clicking on something totally random that I can't see. Is this a bug in the ComboBox? I'm using Windows 7 if that matters. Am I configuring the ComboBox wrong somehow? Note also that using the KEYBOARD uses the autocomplete drop down. So up/down arrow keys are using the front window, but the mouse is using the back window.

• Need to override drawrect if your UIView is merely a container?

  - by Greg Maletic

  According to Apple's docs, "Subclasses need not override -[UIView drawRect:] if the subclass is a container for other views." I have a custom UIView subclass that is indeed merely a container for other views. Yet the contained views aren't getting drawn. Here's the pertinent code that sets up the custom UIView subclass: - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { // Consists of both an "on" light and an "off" light. We flick between the two depending upon our state. self.onLight = [[[LoyaltyCardNumberView alloc] initWithFrame:frame] autorelease]; self.onLight.backgroundColor = [UIColor clearColor]; self.onLight.on = YES; [self addSubview:self.onLight]; self.offLight = [[[LoyaltyCardNumberView alloc] initWithFrame:frame] autorelease]; self.offLight.backgroundColor = [UIColor clearColor]; self.offLight.on = NO; [self addSubview:self.offLight]; self.on = NO; } return self; } When I run the code that displays this custom UIView, nothing shows up. But when I add a drawRect method... - (void)drawRect:(CGRect)rect { [self.onLight drawRect:rect]; [self.offLight drawRect:rect]; } ...the subviews display. (Clearly, this isn't the right way to be doing this, not only because it's contrary to what the docs say, but because it -always- displays both subviews, completely ignoring some other code in my UIView that sets the hidden property of one of the views, it ignores the z-ordering, etc.) Anyway, the main question: why don't my subviews display when I'm not overriding drawRect:? Thanks!

• Detailed android activity lifecycle (onAttachedToWindow())

  - by Ralkie

  I'm interested in android activity lifecycle and I would like to get more detailed description/documentation/reference than widely available basic (onCreate-onStart-onResume) one. My need comes from realizing that starting new activity (Theme.Dialog styled) from onAttachedToWindow() greatly improves response time if comparing to starting it from onCreate(). I wonder how this onAttachedToWindow() fits into whole android activity lifecycle. Official API ref description "Called when the window has been attached to the window manager" doesn't help a lot.

• How * tag can be used in CSS?

  - by php html

  I'm trying to understand how a background image is used in a css button. It seems the image is much larger than the button, still the corners are matched to the button(resulting a rounded corner button). It seems it is related to .btn *. I couldn't find any reference about how * can be used. Can you explain how the image is rendered in the button, using the * tag? I assume * will match any element. However I don't get it how in this case the image is rendered like this. .btn { display: block; position: relative; background: #aaa; padding: 5px; float: left; color: #fff; text-decoration: none; cursor: pointer; } .btn * { font-style: normal; background-image: url(btn2.png); background-repeat: no-repeat; display: block; position: relative; } full example here: http://monc.se/kitchen/59/scalable-css-buttons-using-png-and-background-colors/

• Working with XML...

  - by gsvirdi

  I'm planning to create a news item which uses xml as it's backend and the Display should be like: Date: 08/Mar/2010 Title | News News 4 | Some news News 3 | Some news News 2 | Some news News 1 | Some news Date: 07/Mar/2010 Title | News News 5 | Some news News 4 | Some news News 3 | Some news News 2 | Some news News 1 | Some news Display should be sorted on Date (descending) Then news items should be sorted on time (descending) Today's news item should be on top, then titles should be sorted-decending (timewise), later will come previous day's news items. I'm not able to come up with the logic of xml which should be used in this case. moreover I'm not able to figure out how should I check "Today's date" in xml's "if" statement. ---- Previous Question ------------------------------------------------------------------ How can I export a data from textBox1, textBox2 & textBox3 on my winform (visual studio C#) so that it can automatically create an xml file with proper placing of these data???? Let's say: textBox1 = Name: textBox2 = Age: textBox3 = Roll No It would be great if the exported xml can be appended (add the new data in the EOF) if we export the data again. Any idea plz.....

• Can't Deploy or Upload Large SSRS 2008 Report from VS or IE

  - by Bratch

  So far in this project I have two reports in VS2008/BIDS. The first one contains 1 tablix and is about 100k. The second one contains 3 tablixes (tablices?) and is about 257k. I can successfully deploy the smaller report from VS and I can upload it from the Report Manager in IE. I can view/run it from Report Manager and I can get to the Report Server (web service) URL from my browser just fine. Everything is done over HTTPS and there is nothing wrong with the certificates. With the larger report, the error I get in VS is "The operation has timed out" after about 100 seconds. The error when I upload from IE is "The underlying connection was closed: An unexpected error occurred on a send" after about 130 seconds. In the RSReportServer.config file I tried changing Authentication/EnableAuthPersistence from true to false and restarting the service, but still get the error. I have the key "SecureConnectionLevel" set to 2. Changing this to 0 and turning off SSL is not going to be an option. I added a registry key named "MaxRequestBytes" to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\HTTP\Parameters and set it to 5242880 (5MB) and restarted the HTTP and SRS services as suggested in a forum post by Jin Chen of MSFT. I still cannot upload the larger report. This is on MS SQL 2008 and WS 2003. Below is part of a log file entry from ...\Reporting Services\LogFiles when I attempted to upload from IE. library!WindowsService_0!89c!02/10/2010-07:57:57:: i INFO: Call to CleanBatch() ends ui!ReportManager_0-1!438!02/10/2010-07:59:33:: e ERROR: The underlying connection was closed: An unexpected error occurred on a send. ui!ReportManager_0-1!438!02/10/2010-07:59:34:: e ERROR: HTTP status code -- 500 -------Details-------- System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. --- System.IO.IOException: Unable to write data to the transport connection: An established connection was aborted by the software in your host machine. --- System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine at System.Net.Sockets.Socket.MultipleSend(BufferOffsetSize[] buffers, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.MultipleWrite(BufferOffsetSize[] buffers) --- End of inner exception stack trace --- ...

How can I get an embedded Jetty server up and running with full JSTL support?

• Spring Security - Persistent Remember Me Issue

  - by Taylor L

  I've been trying to track down why Spring Security isn't creating the Spring Security remember me cookie (SPRING_SECURITY_REMEMBER_ME_COOKIE). At first glance, the logs make it seem like the login is failing, but the login is actually successful in the sense that if I navigate to a page that requires authentication I am not redirected back to the login page. However, the logs appear to be saying the login credentials are invalid. I'm using Spring 3.0.1, Spring Security 3.0.1, and Google App Engine 1.3.1. Any ideas as to what is going on?

• Reporting a WCF application's status to F5's Big IP products

  - by ng5000

  In a Windows Server 2003 environment with a self hosted .Net 3.5/WCF application, how can an application report its status to a BigIP Local Traffic Manager? Example: One of my services errors. My custom WCF application hosting software (written because Windows Server 2008 is not yet available and I'm using WCF TCP bindings) detects this and wants to report itself as down until it can recover the errant service. It needs to report itself as down to the BigIP LTM so that it is no longer sent client originated requests.

• Atomikos vs JOTM vs Bitronix vs ????

  - by HDave

  I am new to JTA and it's underlying transaction managers. Can anyone explain the pros/cons of each of these? Feel free to add others I didn't list in title. Also, don't the major applications servers (WebSphere, JBoss, Glassfish) have their own JTA compliant transaction manager? In those environments, would you still use these third party implementations?

  - by Kevin
