• Dashboard for collaborative science / data processing projects

  - by rescdsk

  Hi, Continuous Integration servers like Hudson are a pretty amazing addition to software development. I work in an academic research lab, and I'd love to apply similar principles to scientific data analysis. I want a dashboard-like view of which collections of data are fine, which ones are failing their tests (simple shell scripts, mostly), and so on. A lot like the Chromium dashboard (WARNING: page takes a long time to load). It takes work from at least 4 people, and maybe 10 or 12 hours of computer time, to bring our data (from behavioral studies) from its raw form to its final, easily-analyzed form. I've tried Hudson and buildbot, but neither is really appropriate to our workflow. We just want to run a bunch of tests on maybe fifty independent collections of subject data, and display the results nicely. SO! Does anyone have a recommendation of a way to generate this kind of report easily? Or, can you think of a good way to shoehorn this kind of workflow into a continuous integration server? Or, can you recommend a unit testing dashboard that could deal with tests that are little shell scripts rather than little functions? Thank you!

• how to display a JFrame from an applet?

  - by mithun1538

  Hello everyone, I have this class called PollFrame that extends JFrame in a file called PollFrame.java . PollFrame contains a form. I have an applet, which has a button in it. When the button is clicked, I want the PollFrame to be displayed. I set the ActionPerformed as: Pollframe poll = new PollFrame(); // This initializes the form poll.setVisible(true); However, when I click the button, I get the following error : Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.lang.RuntimePermission exitVM.0) at java.security.AccessControlContext.checkPermission(Unknown Source) at java.security.AccessController.checkPermission(Unknown Source) at java.lang.SecurityManager.checkPermission(Unknown Source) at java.lang.SecurityManager.checkExit(Unknown Source) at javax.swing.JFrame.setDefaultCloseOperation(Unknown Source) at com.org.pollFrame.initComponents(pollFrame.java:54) at com.org.pollFrame.<init>(pollFrame.java:11) at com.org.EmployeeApplet.requestRoomActionPerformed(EmployeeApplet.java:216) at com.org.EmployeeApplet.access$300(EmployeeApplet.java:7) at com.org.EmployeeApplet$4.actionPerformed(EmployeeApplet.java:71) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) I am guessing fromt he above error that calling another class file from an applet is prohibited. Is there any way I can display the PollFrame from the applet?

• Sending Email from Lotus Notes using Excel and having Attachment & HTML body

  - by Anthony

  Right I'm trying to send an Email form an excel spreadsheet though lotus notes, it has an attachment and the body needs to be in HTML. I've got some code that from all I've read should allow me to do this however it doesn't. Without the HTML body the attachment will send, when I impliment a HTML body the Email still sends but the attachment dissapears, I've tried rearanging the order of the code cutting out bits that might not be needed but all is invain. (You need to reference Lotus Domino Objects to run this code. strEmail is the email addresses strAttach is the string location of the attachment strSubject is the subject text strBody is the body text ) Sub Send_Lotus_Email(strEmail, strAttach, strSubject, strBody) Dim noSession As Object, noDatabase As Object, noDocument As Object Dim obAttachment As Object, EmbedObject As Object Const EMBED_ATTACHMENT As Long = 1454 Set noSession = CreateObject("Notes.NotesSession") Set noDatabase = noSession.GETDATABASE("", "") 'If Lotus Notes is not open then open the mail-part of it. If noDatabase.IsOpen = False Then noDatabase.OPENMAIL 'Create the e-mail and the attachment. Set noDocument = noDatabase.CreateDocument Set obAttachment = noDocument.CreateRichTextItem("strAttach") Set EmbedObject = obAttachment.EmbedObject(EMBED_ATTACHMENT, "", strAttach) 'Add values to the created e-mail main properties. With noDocument .Form = "Memo" .SendTo = strEmail '.Body = strBody ' Where to send the body if HTML body isn't used. .Subject = strSubject .SaveMessageOnSend = True End With noSession.ConvertMIME = False Set Body = noDocument.CreateMIMEEntity("Body") ' MIMEEntity to support HTML Set stream = noSession.CreateStream Call stream.WriteText(strBody) ' Write the body text to the stream Call Body.SetContentFromText(stream, "text/html;charset=iso-8859-1", ENC_IDENTITY_8BIT) noSession.ConvertMIME = True 'Send the e-mail. With noDocument .PostedDate = Now() .Send 0, strEmail End With 'Release objects from the memory. Set EmbedObject = Nothing Set obAttachment = Nothing Set noDocument = Nothing Set noDatabase = Nothing Set noSession = Nothing End Sub If somone could point me in the right direction I'd be greatly appreciated. Edit: I've done a little more investigating and I've found an oddity, if i look at the sent folder the emails all have the paperclip icon of having an attachment even though when you go into the email even in the sent the HTML ones don't show an attachment.

• Asp.Net MVC2 Clientside Validation problem with controls with prefixes

  - by alexander

  The problem is: when I put 2 controls of the same type on a page I need to specify different prefixes for binding. In this case the validation rules generated right after the form are incorrect. So how to get client validation work for the case?: the page contains: <% Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.PhonePhone, Prefix = "PhonePhone" }); Html.RenderPartial(ViewLocations.Shared.PhoneEditPartial, new PhoneViewModel { Phone = person.FaxPhone, Prefix = "FaxPhone" }); %> the control ViewUserControl<PhoneViewModel>: <%= Html.TextBox(Model.GetPrefixed("CountryCode"), Model.Phone.CountryCode) %> <%= Html.ValidationMessage("Phone.CountryCode", new { id = Model.GetPrefixed("CountryCode"), name = Model.GetPrefixed("CountryCode") })%> where Model.GetPrefixed("CountryCode") just returns "FaxPhone.CountryCode" or "PhonePhone.CountryCode" depending on prefix And here is the validation rules generated after the form. They are duplicated for the field name "Phone.CountryCode". While the desired result is 2 rules (required, number) for each of the FieldNames "FaxPhone.CountryCode", "PhonePhone.CountryCode" The question is somewhat duplicate of http://stackoverflow.com/questions/2675606/asp-net-mvc2-clientside-validation-and-duplicate-ids-problem but the advise to manually generate ids doesn't helps.

• Trouble pre-populating drop down and textarea from MySQL Database

  - by Tony

  I am able to successfully pre-populate my questions using the following code: First Name: <input type="text" name="first_name" size="30" maxlength="20" value="' . $row[2] . '" /><br /> However, when I try to do the same for a drop down box and a textarea box, nothing is pre-populated from the database, even though there is actual content in the database. This is the code I'm using for the drop down and textarea, respectively: <?php echo ' <form action ="edit_contact.php" method="post"> <div class="contactfirstcolumn"> Prefix: <select name = "prefix" value="' . $row[0] . '" /> <option value="blank">--</option> <option value="Dr">Dr.</option> <option value="Mr">Mr.</option> <option value="Mrs">Mrs.</option> <option value="Ms">Ms.</option> </select><br />'; ?> AND Contact Description:<textarea id = "contactdesc" name="contactdesc" rows="3" cols="50" value="' . $row[20] . '" /></textarea><br /><br /> It's important to note that I am not receiving any errors. The form loads fine, however without the data for the drop down and textarea fields. Thanks! Tony

• PHP, MySQL Per row output

  - by Jake

  Been all over the place and spent 8 hours working loops and math...still cant get it... I am writing a CP for a customer. The input form will allow them to add a package deal to their web page. Each package deal is stored in mysql in the following format id header item1 item2 item3...item12 price savings The output is a table with 'header' being the name of the package and each item being 1 of the items in the package stored in a row within the table, then the price and amount saved (all of this is input via a form and INSERT statement by the customer, that part works) stored rows as well. Here is my PHP: include 'dbconnect.php'; $query = "SELECT * FROM md "; $result = mysql_query($query); while ($row = mysql_fetch_array($result)) { //Print 4 tables with header, items, price, savings //Go to next row (on main page) and print 4 more items //Do this until all tables have been printed } mysql_free_result($result); mysql_close($conn); ? Right now the main page is simpley a header div, main div, content wrap and footer div. Ideal HTML output of a 'package' table, not perfect and a little confusing $header $item1 $item2 ect... $price$savings I basically want the PHP to print this 4 times per row on the main page and then move to the next row and print 4 times and continue until there are no more items in the array. So it could be row 1 4 tables, row 2 4 tables, row 3 3 tables. Long, confusing and frustrating. I about to just do 1 item per row..please help Jake

• Problems with zend-tool reporting that providers are not valid

  - by Mario

  I have recently setup XAMPP 1.7.3 and ZendFramework 1.10.4 on a new computer and many of the commands that I normally use now fail. Here are the steps I used to setup and test ZF. First I added the ZF library folder (C:\xampp\php\ZendFramework-1.10.4\library) to the include path in php.ini. Then I added the ZF bin folder (C:\xampp\php\ZendFramework-1.10.4\bin) to my Path system variable. To test that everything is configured correctly I ran the command "zf show version" from the command line. The result is "Zend Framework Version: 1.9.6". Immediately something appears to be wrong. The file that is downloaded is "ZendFramework-1.10.4.zip" and the reported version is 1.9.6. I have re-downloaded the latest version (1.10.4) and removed old copy. Still the incorrect version number problem persisted. Having done some research there is a bug in the ZF knowledgebase that version 1.10.3 reports a wrong version number. So that may explain the version number problem. Moving forward I tried to run some zf-tool commands and certain commands reports that the action or provider is not valid. Example: C:\xampp\htdocs>zf create project test Creating project at C:/xampp/htdocs/test C:\xampp\htdocs>cd test C:\xampp\htdocs\test>zf create controller Test Creating a controller at C:\xampp\htdocs\test/application/controllers/TestController.php ... Updating project profile 'C:\xampp\htdocs\test/.zfproject.xml' C:\xampp\htdocs\test>zf create action test Test Creating an action named test inside controller at C:\xampp\htdocs\test/application/controllers/TestController.php ... Updating project profile 'C:\xampp\htdocs\test/.zfproject.xml' C:\xampp\htdocs\test>zf enable layout An Error Has Occurred Action 'enable' is not a valid action. ... C:\xampp\htdocs\test>zf create form Test An Error Has Occurred Provider 'form' is not a valid provider. ... Can any one provide insight into these errors and how to correct them?

• Combine NotifyIcon and ToolTip

  - by Greycrow

  I have been working with NotifyIcon in order to show an icon in the taskbar. This program has no Windows Form. I perhaps could create one and make it invisible but I was hoping to avoid it. The ToolTip functions attached to NotifyIcon are somewhat lacking, and one of the gurus here suggested I look at the ToolTip functionality. It is possible to attach ToolTip to a form. Is is possible to attach it to just the NotifyIcon? I'm trying do this: NotifyIcon CTicon = new NotifyIcon(); ToolTip toolTip = new ToolTip(); toolTip.SetToolTip(CTicon, "Test"); And I get the error "cannot convert from 'System.Windows.Forms.NotifyIcon' to 'System.Windows.Forms.Control'. Is there a way to convert? I also tried: toolTip.SetToolTip(CTicon.Container, "Test"); but a container is apparently not a valid control either. I apologize for my total lack of understanding of how this may or may not work. Thanks in advance.

• nested attributes with polymorphic has_one model

  - by Millisami

  I am using accepts_nested_attributes_for with the has_one polymorphic model in rails 2.3.5 Following are the models and its associations: class Address < ActiveRecord::Base attr_accessible :city, :address1, :address2 belongs_to :addressable, :polymorphic => true validates_presence_of :address1, :address2, :city end class Vendor < ActiveRecord::Base attr_accessible :name, :address_attributes has_one :address, :as => :addressable, :dependent => :destroy accepts_nested_attributes_for :address end This is the view: - form_for @vendor do |f| = f.error_messages %p = f.label :name %br = f.text_field :name - f.fields_for :address_attributes do |address| = render "shared/address_fields", :f => address %p = f.submit "Create" This is the partial shared/address_fields.html.haml %p = f.label :city %br= f.text_field :city %span City/Town name like Dharan, Butwal, Kathmandu, .. %p = f.label :address1 %br= f.text_field :address1 %span City Street name like Lazimpat, New Road, .. %p = f.label :address2 %br= f.text_field :address2 %span Tole, Marg, Chowk name like Pokhrel Tole, Shanti Marg, Pako, .. And this is the controller: class VendorsController < ApplicationController def new @vendor = Vendor.new end def create @vendor = Vendor.new(params[:vendor]) if @vendor.save flash[:notice] = "Vendor created successfully!" redirect_to @vendor else render :action => 'new' end end end The problem is when I fill in all the fileds, the record gets save on both tables as expected. But when I just the name and city or address1 filed, the validation works, error message shown, but the value I put in the city or address1, is not persisted or not displayed inside the address form fields? This is the same case with edit action too. Though the record is saved, the address doesn't show up on the edit form. Only the name of the Client model is shown. Actually, when I look at the log, the address model SQL is not queried even at all.

• Paperclip wont save image in rails app

  - by Micke

  Hello stackoverflow. I am trying to use Paperclip with my rails app to add an avatar to a user but it wont save my image when creating the user. This is what the model looks like: class User < ActiveRecord::Base has_attached_file :avatar And the registerform in haml: - form_for :user, @user, :url => { :action => "signup" }, :html => { :multipart => true } do |f| ... ... %li %div{:class => "header"} Profilepicture %div{:class => "input"} = f.file_field :avatar And when i look in the log this is what is being passet to the "signup" action: Parameters: {"commit"=>"Save", "action"=>"signup", "controller"=>"user/register", "user"=>{"name"=>"Micke Lisinge", "birthmonth"=>"07", "password_confirmation"=>"[FILTERED]", "nickname"=>"lisinge", "avatar"=>#<File:/tmp/RackMultipart20100426-3076-1x04oxy-0>, "gen"=>"m", "birthday"=>"23", "password"=>"[FILTERED]", "birthyear"=>"1992", "email"=>"[email protected]"}} [paperclip] Saving attachments. Paperclip says it is saving the template but when i look in the public folder in my app it has created a system but the system folder is empty. So it seems like it isnt saving the picture to the folder. It gets handled by the form and saved in my /tmp folder. Maybe you guys have any tips or know what this problem might be? Thanks in advance, Micke.

• How to improve the use of Delphi Frames

  - by Brian Frost

  I've used frames in Delphi for years, and they are one of the most powerful features of the VCL, but standard use of them seems to have some risk such as: It's easy to accidentally move or edit the frame sub-components on a frame's host form without realising that you are 'tweaking' with the frame - I know this does not affect the original frame code, but it's generally not what you would want. When working with the frame you are still exposed to its sub-components for visual editing, even when that frame is years old and should not be touched. So I got to thinking.... Is there a way of 'grouping' components such that their positions are 'locked'? This would be useful for finished forms as well as frames. Often other developers return code to me where only the form bounds have changed and even they did not intend any change. Is there any way of turning a frame and its components into a single Delphi component? If so, the frame internals would be completely hidden and its useability would increase further. I'm interested in any thoughts... Brian.

• JSF 2.0: Validate equality of 2 InputSecret Fields (confirm password) without writing Code?

  - by yournamehere

  I'm developing a pure JavaEE6 application with JSF 2.0 and Glassfish. My JSF implementation is Primefaces (beside Mojarra provided by Glassfish). I want to verify if the values of 2 password fields in a JSF form are equal. With Seam, there is the neat component <s:validateEquality for="pw1"/>. I want do to the same without Seam, just using JSF (or maybe a component of a JSF library). Until now i only saw examples which validate the form with a custom validator. But i would like to compare the fields without writing Java code or Javascript code. Is that possible? This what it looks like with Seam: ... <h:inputSecret id="passwort" value="#{personHome.instance.password}" redisplay="true" required="true"> <f:validateLength minimum="8"/> <a:support event="onblur" reRender="passwortField" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... <h:inputSecret id="passwort2" required="true" redisplay="true"> <!-- find the JSF2.0-equivalent to this tag: --> <s:validateEquality for="passwort"/> <a:support event="onblur" reRender="passwort2Field" bypassUpdates="true" ajaxSingle="true" /> </h:inputSecret> ... Any help is appreciated. Thanks!

• Why ComboBox hides cursor when DroppedDown is set?

  - by Ivan Danilov

  Let's create WinForms Application (I have Visual Studio 2008 running on Windows Vista, but it seems that described situation takes place almost everywhere from Win98 to Vista, on native or managed code). Write such code: using System; using System.Drawing; using System.Windows.Forms; namespace WindowsFormsApplication1 { public class Form1 : Form { private readonly Button button1 = new Button(); private readonly ComboBox comboBox1 = new ComboBox(); private readonly TextBox textBox1 = new TextBox(); public Form1() { SuspendLayout(); textBox1.Location = new Point(21, 51); button1.Location = new Point(146, 49); button1.Text = "button1"; button1.Click += button1_Click; comboBox1.Items.AddRange(new[] {"1", "2", "3", "4", "5", "6"}); comboBox1.Location = new Point(21, 93); AcceptButton = button1; Controls.AddRange(new Control[] {textBox1, comboBox1, button1}); Text = "Form1"; ResumeLayout(false); PerformLayout(); } private void button1_Click(object sender, EventArgs e) { comboBox1.DroppedDown = true; } } } Then, run app. Place mouse cursor on the form and don't touch mouse anymore. Start to type something in TextBox - cursor will hide because of it. When you press Enter key - event throws and ComboBox will be dropped down. But now cursor won't appear even if you move it! And appears only when you click somewhere. There I've found discussion of this problem. But there's no good solution... Any thoughts? :)

• How to determine if DataGridView contains uncommitted changes when bound to a SqlDataAdapter

  - by JYelton

  I have a form which contains a DataGridView, a BindingSource, a DataTable, and a SqlDataAdapter. I populate the grid and data bindings as follows: private BindingSource bindingSource = new BindingSource(); private DataTable table = new DataTable(); private SqlDataAdapter dataAdapter = new SqlDataAdapter("SELECT * FROM table ORDER BY id ASC;", ClassSql.SqlConn()); private void LoadData() { table.Clear(); dataGridView1.AutoGenerateColumns = false; dataGridView1.DataSource = bindingSource; SqlCommandBuilder commandBuilder = new SqlCommandBuilder(dataAdapter); table.Locale = System.Globalization.CultureInfo.InvariantCulture; dataAdapter.Fill(table); bindingSource.DataSource = table; } The user can then make changes to the data, and commit those changes or discard them by clicking either a save or cancel button, respectively. private void btnSave_Click(object sender, EventArgs e) { // save everything to the displays table dataAdapter.Update(table); } private void btnCancel_Click(object sender, EventArgs e) { // alert user if unsaved changes, otherwise close form } I would like to add a dialog if cancel is clicked that warns the user of unsaved changes, if unsaved changes exist. Question: How can I determine if the user has modified data in the DataGridView but not committed it to the database? Is there an easy way to compare the current DataGridView data to the last-retrieved query? (Note that there would not be any other threads or users altering data in SQL at the same time.)

  I'm using PHP to read if an entry in my table on the database is set to "yes" or "no" and auto check the radio button that corresponds: <?php include 'file.php'; $query = "SELECT * FROM TABLE"; $runquery = odbc_exec($connect,$query); $status= odbc_result($runquery,"status"); odbc_close($file); ?> <form> <div class="formContainer"> <fieldset> <legend>Campus Alert<span class="tooltip">Turn campus alert on and off.</span></legend> <?php echo $status; ?> Yes <input type="radio" name="alertStatus" id="alertStatus" value="yes" <?php if($status== "yes") echo "checked";?>> No <input type="radio" name="alertStatus" id="alertStatus" value="no" <?php if($status== "no") echo "checked";?>> </fieldset> </div> the is for debugging so I can make sure what the database says and the form's reaction is correct. It prints "yes" (no quotes). However, the if statement will not respond. Any idea why it's doing this?

• Styling an Input Field

  - by John

  Hello, How can I give the input field below the characteristics listed below? Characteristics: -Text typed into the field starts in the upper left corner and starts on another line (wraps?) when the right border of the field is reached. -A scroll bar appears if the text is more than what can fit into the field. -The text is in Courier font. Thanks in advance, John echo '<form action="http://www...com/sandbox/comments/comments2.php" method="post"> <input type="hidden" value="'.$_SESSION['loginid'].'" name="uid"> <input type="hidden" value="'.$submissionid.'" name="submissionid"> <input type="hidden" value="'.$submission.'" name="submission"> <label class="addacomment" for="title">Add a comment:</label> <input class="commentsubfield" name="comment" type="comment" id="comment" maxlength="1000"> <div class="commentsubbutton"><input name="submit" type="submit" value="Submit"></div> </form> '; Some relevant CSS: .commentsubfield {margin-left: 30px; margin-top: 30px; width: 390px; height: 90px; border: 1px solid #999999; padding: 5px; }

• Ideas on C# DSL syntax

  - by Dmitriy Nagirnyak

  Hi, I am thinking about implementing a templating engine using only the plain C#/.NET 4 syntax with the benefit of static typing. Then on top of that templating language we could create Domain Specific Languages (let's say HTML4, XHTML, HTML5, RSS, Atom, Multipart Emails and so on). One of the best DSLs in .NET 4 (if not only one) is SharpDOM. It implements HTML-specific DSL. Looking at SharpDOM, I am really impressed of what you can do using .NET (4). So I believe there are some not-so-well-known ways for implementing custom DSLs in .NET 4. Possibly not as well as in Ruby, but still. So my the question would be: what are the C# (4) specific syntax features that can be used for implementing custom DSLs? Examples I can think of right now: // HTML - doesn't look tooo readable :) div(clas: "head", ul(clas: "menu", id: "main-menu", () => { foreach(var item in allItems) { li(item.Name) } }) // See how much noise it has with all the closing brackets? ) // Plain text (Email or something) - probably too simple Line("Dear {0}", user.Name); Line("You have been kicked off from this site"); For me it is really hard to come up with the syntax with least amount of noise. Please NOTE that I am not talking about another language (Boo, IronRuby etc), neither I am not talking about different templating engines (NHaml, Spark, StringTemplate etc). Thanks, Dmitriy.

• How do you determine subtype of an entity using Inheritance with Entity Framework 4?

  - by KallDrexx

  I am just starting to use the Entity Framework 4 for the first time ever. So far I am liking it but I am a bit confused on how to correctly do inheritance. I am doing a model-first approach, and I have my Person entity with two subtype entities, Employee and Client. EF is correctly using the table per type approach, however I can't seem to figure out how to determine what type of a Person a specific object is. For example, if I do something like var people = from p in entities.Person select p; return people.ToList<Person>(); In my list that I form from this, all I care about is the Id field so i don't want to actually query all the subtype tables (this is a webpage list with links, so all I need is the name and the Id, all in the Persons table). However, I want to form different lists using this one query, one for each type of person (so one list for Clients and another for Employees). The issue is if I have a Person entity, I can't see any way to determine if that entity is a Client or an Employee without querying the Client or Employee tables directly. How can I easily determine the subtype of an entity without performing a bunch of additional database queries?

• using ResultSet.Previous method not working in Java using .mdb file OBDC

  - by jsonnie

  Hello, I'm currently having an issue with my open result set not working how I believe it should. The only function that is currently working is the next() method, nothing else will work. If the project is placed into a debug mode you can follow through actionperformed event on the button it hits the previous() method and jumps over the remaining code in the method. If someone could point me in the right direction it would be truly appreciated.

• TinyMCE + jQuery + custom plugin = tinymce is undefined?

  - by user368691

  The problem occurs when I try to create small plugin to allow me toggle on and off WYSIWYG on all textareas in the website. //$('form.default textarea').each(function(){ // console.log( $('<a href="#">Enable WYSIWYG editor</a>').insertAfter('form.default textarea').prev('textarea.wysiwyg').tinymce().hide() ); //}); The full (a bit simplified) code looks like this: $('textarea.wysiwyg').tinymce({ skin : 'cirkuit', theme : 'advanced', plugins : 'pagebreak,style,layer,advlink,inlinepopups,contextmenu,paste,directionality,noneditable,nonbreaking,xhtmlxtras,template', // Theme options theme_advanced_buttons1 : 'formatselect,fontsizeselect,forecolor,|,bold,italic,strikethrough,|,bullist,numlist,|,justifyleft,justifycenter,justifyright,|,link,unlink,|,image,|,code,paste,pastetext,pasteword,removeformat,|,backcolor,|,underline,justifyfull,sup,|,outdent,indent,|,hr,charmap,|,undo,redo', theme_advanced_buttons2 : '', theme_advanced_buttons3 : '', theme_advanced_toolbar_location : 'top', theme_advanced_toolbar_align : 'left', theme_advanced_statusbar_location: 'bottom', theme_advanced_resizing : true, theme_advanced_resize_horizontal : false, height : 500, theme_advanced_resizing_min_height : 500, document_base_url : 'http://static.<?=$settings['system_host']?>/' }); $('textarea.wysiwyg').each(function() { $(this).tinymce().hide(); }); What is the error? FireBug says that tinymce() in undefined; this message occurs in each() loop. Thus, tinymce() is actually initialized. I am really lost towards, what could be causing this.
