• What kind of hosting do I need? [closed]

  - by Robert Smith

  I have been trying to answer this question but I haven't found an specific answer to my situation. As I want to pay for what I need, I thought I could get a good answer here. I have custom made forum (rather than a built-in forum like the ones you can find as plugins, e.g. WP-Forum or phpBB type of software) in Django. I don't want to use Apache and modwsgi because it's usually very memory-hungry and I can't afford a big server. I prefer a combination of nginx and gunicorn which I think is very efficient (maybe you can also tell me what you think about that). I'm expecting to receive 10,000 to 20,000 visits each month with 15,000 to 30,000 page impressions. I have reviewed some cloud services like Amazon EC2 or Rackspace and other more traditional services (Linodo). This site won't use videos or big images and I certainly don't need a huge amount of bandwidth (200GB would be definitely too much). I need shell access so shared hosting is out of the question. What do I need to run a website like that without problems? What about RAM? 256MB would be enough (that's the amount of RAM offered by small instances in Amazon and Rackspace)? Do you know of any alternative to those I mentioned? If you need more information to provide a useful answer, please don't hesitate to ask. Thanks a lot.

• MySQL Server 5.6 default my.cnf and my.ini

  - by user12626240

  We've introduced a default my.cnf / my.ini file for MySQL Server that you can now see in the 5.6.8 release candidate: # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.6/en/server-configuration-defaults.html [mysqld] # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M   # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin   # These are commonly set, remove the # and set as required. # basedir = ..... # datadir = ..... # port = ..... # socket = ..... # server_id = .....   # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M   sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES    There is also a template file called my-default.cnf or my-default.ini that has these lines near the start: # *** DO NOT EDIT THIS FILE. It's a template which will be copied to the # *** default location during install, and will be replaced if you # *** upgrade to a newer version of MySQL.   On Linux systems, the mysql_install_db command will copy the template file to the final location, where the server will read and use the file, removing the extra three lines. On Windows, the installer will create extra settings based on the answers you gave during installation. Neither will overwrite an existing my.cnf or my.ini file. The only initially active setting here is to change the value of  sql_mode from the server default of NO_ENGINE_SUBSTITUTION to NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES. This strict mode changes warnings for some non-standard behaviour into errors. This can cause applications which rely on the non-standard things, like dates that aren't valid, to lose data. If we had just changed the server default, the new setting would affect all servers that lack an explicit sql_mode setting, including those where strict mode is harmful. So we did it in the default file instead because that will only affect new server installations. You should expect that in our next version after 5.6, the server default will include STRICT_TRANS_TABLES. Our Windows installer and some of our connectors already use STRICT_TRANS_TABLES by default. Strict has been our preferred setting for many years and it is good to see some development platforms are using it. If you need the old behaviour, just remove the STRICT_TRANS_TABLES setting. If you do this, please also ask your application provider to make it unnecessary. They can do that by setting the session sql_mode setting in their own connections, so the rest of the applications using the server don't have to have an undesirable default. We've kept this file as small as possible because we found that our old files were too big and confused people. We've also now removed the old my-huge and related example files. One key part of this is the link to the documentation, where we will provide an introduction to some key settings. We'd like to hear your feedback on settings that will benefit most users or are most important to call out for existing users. Please do that by commenting here or if you prefer by adding comments to this bug report.

• Hostname vs webpage domain.

  - by Mark

  Hi All, Im just starting to look at deploying a webpage and get into the joy of DNS etc. And im wondering how you set up multiple web-servers all with thier own hostnames/public IP addresses, and yet have them serve up a webpage from one domain. For example, lets say you have a website example.com, and an A record in DNS that points at it's IP address of 1.2.3.4 . You want to have two servers, prod1 and prod2 with some kind of load balancer in front of them for fail over reasons. The way I see it you would want to have the hostnames of these servers as prod1.example.com and prod2.example.com and perhaps loadb.example.com. How would you set up the DNS so this would all work. ie you could ssh to any of the server domains, prod1.example.com, prod2.example.com or loadb.example.com and also just use the www.example.com url to go to the website. And would all these server names be resolvable from the public internet and is that safe? This would be a linux environment, for arguments sake ubuntu, a django framework dynamic website, running in apache 2.2 Cheers Mark

• solution for an offline server

  - by dashmug

  I'm trying to setup a development server at work that will ideally be able to test drive a couple of projects in PHP, Rails, or Django (not always running at the same time). I develop the apps locally on a Mac and then I'll put the projects up on this server for testing with my actual users (non-techies) before deploying to a production server. My problem is that we have a very poor internet connection (almost negligible) at work and doing the usual apt-get/yum/ports (make, clean, install) processes for setting up servers always get their packages from online repositories somewhere. I know I could probably download the source and then compile them myself but that's going to be too much of a hassle for me. I'm thinking about two solutions: Plan A: Run a server VM on my Mac and then use this VM as the source repository for the offline server. I've read about Ubuntu's apt-proxy and it seems to be good enough though I haven't tried it yet. I'm not sure if this is possible but can I simply do apt-get install nginx --downloadonly so that the package and its dependencies will be downloaded into my VM and my server can use the VM as the source repo for apt-get? Plan B: Run a server VM on my Mac (which I can setup/update easily when I'm home) and then clone the VM to the offline development server. Maybe I should simply make the server a VM host so I can simply copy the VM over. I think this is okay for the first-time setup but subsequent updates will take too long (cloning the VM image). If I was working on Windows, I imagine it'd be easier because most services have an installer file that I can download and then run at the server. If you could suggest another way, it would be much appreciated. Update: From Michael Hampton's answer, I found a possible solution which is apt-cacher. I also found this page on Ubuntu's website. I wonder if there is a better tool than this one.

• Open source app to manage and run commands on cloud servers? [closed]

  - by Mark Theunissen

  I'm creating a SaaS platform, and I need a component / library that can create, delete and store the connection details for cloud servers. It also needs to support executing shell commands on these servers and returning the response to the caller. I want a central database of servers and their configuration, plus the ability to reach out and manage the servers via SSH execution of bash scripts. I don't want something that needs agents on every server like Chef. For example, this command is received by the hypothetical application: CREATE USER server = server12345 name = myuser It's translated into the following set of actions and executed by the app, which knows how to connect to server12345, and how to create a user on that server: $ ssh root@server12345 $ adduser myuser And returns the output from the shell: Added user myuser. I've done research on Google and can't quite quite find something that does this already. I've found: fabric This part handles the executing of the shell commands very elegantly, and can take multiple server definitions, but it's supposed to be a deployment tool so doesn't do everything that would be required above - for example, it doesn't have a daemon mode where it listens for commands - it expects to be executed on the shell. It also can't provide the central database functionality. libcloud This library can handle the server admin (CRUD) part, but doesn't have a command interface daemon either, and doesn't let you execute commands on the servers. I guess I need something that is a combination of libcloud, fabric and django for an API. Or something else that does that same thing regardless of language. Overmind Overmind is a GUI and wrapper around libcloud, but doesn't support the command execution part. What am I missing here?

• Excel 2007 - "The macro may not be available in this workbook" Error

  - by Psycho Bob

  We use an Excel sheet that has been protected to prevent modification of it from end users. All in all they are only able to edit certain tabs to add information that will then be used to generate information on other tabs using equations and such. On the tab with the equations, a button is present called "Prep for Internal Hard Copy Print." This button runs a macro that selects the information on the tab, unprotects it, then sends a print job to the user's default printer that contains the unprotected content. Normally this works like a champ. This time around, however, the macro is throwing the following error: Cannot run the macro "FILENAME.xlsx'!MacroName'. The macro may not be available in this workbook or all macros may be disabled. As far as I can tell, the macros are still present within the workbook. This sheet is normally a .xlsm though the user saved it with a different filename as a .xlsx. Also, the macros appear only as MacroName in the .xlsm file and not "FILENAME.xlsx'!MacroName' as it does in the .xlsx. Finally, when I open the .xlsm it asks if I want to enable the macro content while the .xlsx does not prompt for this. Can anyone tell me what's going on with this sheet or know of a way that I can get the macros working in the .xlsx without having to start over with a different sheet?

• WPF: Hide grid row

  - by Richard

  Hi All, I have a simple WPF form with a <Grid> declared on the Form. In this Grid I then have a bunch of Rows: <Grid.RowDefinitions> <RowDefinition Height="Auto" MinHeight="30" /> <RowDefinition Height="Auto" Name="rowToHide"/> <RowDefinition Height="Auto" MinHeight="30" /> </Grid.RowDefinitions> So basically the row with the name "rowToHide" has a few input fields in it, and now I want to hide this row as I don't need these fields. Its simple enough to just set all items in the Row to Visibility = Hidden, but the Row still takes up space in the Grid. So need to do something like setting Height = 0 or something. But that didn't seem to work. You can think of it like this: You have a form, in there we have a drop down saying "Payment Type", and if the person selects "Cash", then hide the row containing the Card details. And it isn't an option to start the form with this hidden already. Thanks everyone!

• jquery parseFloat assigning val to field

  - by user306472

  I have a select box that gives a description of a product along with a price. Depending on what the user selects, I'd like to automatically grab that dollar amount from the option selected and assign it to a price input field. My HTML: <tr> <td> <select class="selector"> <option value="Item One $500">Item One $500</option> <option value="Item Two $400">Item Two $400</option> </select> </td> <td> <input type="text" class="price"></input> </td> </tr> So based on what is selected, I want either 500 or 400 assigned to the .class input. I tried this but I'm not quite sure where I'm going wrong: $('.selector').blur(function(){ var selectVal = ('.selector > option.val()'); var parsedPrice = parseFloat(selectVal.val()); $('.price').val(parsedPrice); });

• 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.

• ExtJS: Combobox in EditorGridPanel not selecting the desired item (with test case)

  - by TomH

  I'm using ExtJS to create an EditorGridPanel with a combobox for an editor in a cell. The combobox in my EditorGridPanel that is not working as I'd expect it to. When the user types the first letter of an item in the drop down list, the combobox seems to ignore it and select the first item in the list. I can reproduce the error consistently and have put together a test case here: http://cluebucket.com/dev/testcase/testcase.html Load the page and reproduce the behavior by the following -- note that this is all done using the keyboard, no mouse clicks: Click 'Add Record' (A new row is added to the grid) enter text in the text field. TAB to the Priority field without selecting anything (None will remain selected) TAB out of the Priority field. (A new row is added to the grid) enter text and TAB to the Priority field TYPE v (Very High is selected) TAB out of the priority field (A new row is added to the grid) enter text and TAB to the Priority field Type v (None is selected, but Very High should have been) TAB out of the priority field Enter text and TAB to the priority field Type l ('el') (Low is selected) TAB out, enter text, TAB to priority Type l (None is selected) It appears that whenever the user attempts to select the same value that was selected in the previous row, the combobox selects None. Any ideas? The code is available at cluebucket.com/dev/testcase/js/testcase.js Thoughts/Pointers/Corrections are appreciated!! thanks tom

• Combobox with collection view itemssource does not update selection box item on changes to the Model

  - by Vinit Sankhe

  Hello, Sorry for the earlier lengthy post. Here is my concise (!) description. I bind a collection view to a combobox as a itemsSource and also bind its selectedvalue with a property from my view model. I must keep IsSynchronizedWithCurrentItem="False". I change the source list ofr the view and then refresh the view. The changed (added, removed, edited) items appear correctly in the item list of the combo. But problem is with the selected item. When I change its property which is also the displaymember path of the combo, the changed property value does not reflect back on the selecton box of the combo. If you open the combo dropdown it appears correctly on the item list but not on the selection box. Now if I change the combobox tag to Listbox in my XAML (keeping all attributes as it is) then when selected item's displaymember property value is updated, the changes reflect back on the selected item of the list box . Why this issue? Just FYI: My View Model has properties EmployeeCollectionView and SelectedEmployeeId which are bound to combo as ItemsSource and SelectedValue resp. This VM implements the INotifyPropertyChanged interface. My core employee class (list of which is the source for the EmployeeCollectionView) is simply a Model class without INotifyPropertyChanged. DisplayMemberPath is "Name" property of employee Model class. I change this by some means and expect the combo selection box to update the value. I tried refreshing ther SelectedEmployeeId by setting it 0 (where it correctly selects the dummy "-- Select All --" employee entry from itemsSource) and old selected value back. But no use. The old value takes me back to the old label. Items collection has latest entry though. When I make combobox's IsEditable=True before the view's refresh and after refresh I make IsEditable=False then the things work out correctly! But this is a patch and is unnecessary. Thx Vinit Sankhe

• Android: How to keep onItemSelected from firing off on a newly instantiated Spinner

  - by Drennen

  I've thought of some less than elegant ways to solve this, but I know I must be missing something. My onItemSelected fires off immediately without any interaction with the user, and this is undesired behavior. I wish for the UI to wait until the user selects something before it does anything. I even tried setting up the listener in the onResume, hoping that would help, but it doesn't. How can I stop this from firing off before the user can touch the control? THANKS public class CMSHome extends Activity { private Spinner spinner; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // Heres my spinner /////////////////////////////////////////// spinner = (Spinner) findViewById(R.id.spinner); ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.pm_list, android.R.layout.simple_spinner_item); adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapter); }; public void onResume() { super.onResume(); spinner.setOnItemSelectedListener(new MyOnItemSelectedListener()); } public class MyOnItemSelectedListener implements OnItemSelectedListener { public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) { Intent i = new Intent(CMSHome.this, ListProjects.class); i.putExtra("bEmpID", parent.getItemAtPosition(pos).toString()); startActivity(i); Toast.makeText(parent.getContext(), "The pm is " + parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show(); } public void onNothingSelected(AdapterView parent) { // Do nothing. } } }

• C# Winforms TabControl elements reading as empty until TabPage selected

  - by Geo Ego

  I have Winform app I am writing in C#. On my form, I have a TabControl with seven pages, each full of elements (TextBoxes and DropDownLists, primarily). I pull some information in with a DataReader, populate a DataTable, and use the elements' DataBindings.Add method to fill those elements with the current values. The user is able to enter data into these elements, press "Save", and I then set the parameters of an UPDATE query using the elements' Text fields. For instance: updateCommand.Parameters.Add("@CustomerName", SqlDbType.VarChar, 100).Value = CustomerName.Text; The problem I have is that once I load the form, all of the elements are apparently considered empty until I select each tab manually. Thus, if I press "Save" immediately upon loading the form, all of the fields on the TabPages that I have not yet selected try to UPDATE with empty data (not nice). As I select each TabPage, those elements will now send their data along properly. For the time being, I've worked out a (very) ugly workaround where I programmatically select each TabPage when the data is populated for the first time, but that's an unacceptable long-term solution. My question is, how can I get all of the elements on the TabPages to return their data properly before the user selects that TabPage?

• Wordpress SQL Select Multiple Meta Values / Meta Keys / Custom Fields

• How to call RequiredFieldValidator on client before postback

  - by Si

  I've inherited some code which breaks a page up into tabs using divs. On the first page there are many required field and regex validators. The problem is a user can switch to another tab, trigger a postback and fail the validators on the first page, leaving things in a mess. What I want to be able to do is perform the validation on the first page as a user selects another tab, thus preventing them from moving to a new tab until the first page is valid. <ul> <li><a href="#tab1">Tab 1</a> </li> <li><a href="#tab2" onclick="return isValid();">Tab 2</a></li> <li><a href="#tab3" onclick="return isValid();">Tab 3</a></li> </ul> Where isValid needs to fire off the validators. Thanks!

• Programatically insert a Word document into an existing document (Word 2007)

  - by cjb

  I have a Word 2007 document that I want to insert an exsiting Word document into - while preserving the header/footer, graphics, borders etc of both documents. I'm doing this using the Word API in C#. It sounds pretty simple, I mean surely you just use the "InsertFile" method... except that in Word 2007 the "insert file" functionality now is actually "insert text from file" and it does just that - leaving out the page border, graphics and footer etc. OK then, I'll use copy and paste instead, like so... _Document sourceDocument = wordApplication.Documents.Open(insert the 8 million by ref parameters Word requries) sourceDocument.Activate(); // This is the document I am copying from wordApplication.Selection.WholeStory(); wordApplication.Selection.Copy(); targetDocument.Activate(); // This is the document I am pasting into wordApplication.Selection.InsertBreak(wdSectionBreakNextPage); Selection.PasteAndFormat(wdFormatOriginalFormatting); wordApplication.Selection.InsertBreak(wdSectionBreakNextPage); which does what you would expect, takes the source document, selects everything, copies it then pastes it into the target document. Because I've added a section break before doing the paste it also preserves the borders, header/footer of both documents. However - now this is where I have the problem. The paste only includes the borders, header etc if I paste at the end of the target document. If I paste it in the middle - despite there being a preceding section break, then only the text gets pasted and the header and borders etc are lost. Can anyone help before I buy a grenade and a one way ticket to Redmond...

• WPF Memory Leak on XP (CMilChannel, HWND)

  - by vanja.

  My WPF application leaks memory at about 4kb/s. The memory usage in Task Manager climbs constantly until the application crashes with an "Out of Memory" exception. By doing my own research I have found that the problem is discussed here: http://stackoverflow.com/questions/801589/track-down-memory-leak-in-wpf and #8 here: http://blogs.msdn.com/jgoldb/archive/2008/02/04/finding-memory-leaks-in-wpf-based-applications.aspx The problem described is: This is a leak in WPF present in versions of the framework up to and including .NET 3.5 SP1. This occurs because of the way WPF selects which HWND to use to send messages from the render thread to the UI thread. This sample destroys the first HWND created and starts an animation in a new Window. This causes messages sent from the render thread to pile up without being processed, effectively leaking memory. The solution offered is: The workaround is to create a new HwndSource first thing in your App class constructor. This MUST be created before any other HWND is created by WPF. Simply by creating this HwndSource, WPF will use this to send messages from the render thread to the UI thread. This assures all messages will be processed, and that none will leak. But I don't understand the solution! I have a subclass of Application that I am using and I have tried creating a window in that constructor but that has not solved the problem. Following the instructions given literally, it looks like I just need to add this to my Application constructor: new HwndSource(new HwndSourceParameters("MyApplication"));

  Imagine: [RadOutlookBarItem1] [RadOutlookBarItem2] [RadOutlookBar] [CONTENCONTROL] What i want to achieve is: User selects one of the RadOutlookBarItem's. Item's tag is bound like: Tag="{Binding SelectedControl, Mode=TwoWay}" MVVM Property public string SelectedControl { get { return _showControl; } set { _showControl = value; OnNotifyPropertyChanged("ShowControl"); } } ContentControl has multiple CustomControls and Visibility of those is bound like: <UserControl.Resources> <Converters:BoolVisibilityConverter x:Key="BoolViz"/> </UserControl.Resources> <Grid x:Name="LayoutRoot" Background="White"> <Views:ViewDocumentSearchControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewDocumentSearchControl'}"/> <Views:ViewStartControl Visibility="{Binding SelectedControl, Converter={StaticResource BoolViz}, ConverterParameter='viewStartControl'}"/> </Grid> Converter: public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { // here comes the logic part... should return Visibility.Collapsed : Visibility.Visible based on 'object value' value System.Diagnostics.Debugger.Break(); return Visibility.Collapsed; } now, logically the object value is always set to null. So here's it comes to my question: How can i put a value into the SelectedControl Variable for the RadOutlookBarItem's Tag. I mean something like Tag="{Binding SelectedControl, Mode=TwoWay, VALUE='i.e.ControlName'"} So that i can decide, using the Convert Method, whether a specific Control's visibility is either set to collapsed or visible? help's appreciated Christian

• Wix Burn issue: Uninstall fails saying "Found dependent"

  - by vivek chaurasiya

  I have made a burn bundle which encapsulates 2 msi (msi1 , msi2) . In the UI I use checkboxes to ask the user to select which MSI to install. Now if user selects one of the msi to install, installation goes fine. But during Uninstall action, the burn log file says : [][:15]: Detected package: Netfx4Full, state: Present, cached: None [][:15]: Detected package: DummyInstallationPackageId3, state: **Absent**, cached: None [][:15]: Detected package: msi2.msi, state: **Present**, cached: Complete [][:15]: Detect complete, result: 0x0 [][:16]: Plan 3 packages, action: Uninstall [][:16]: Will not uninstall package: msi2.msi, found dependents: 1 [][:16]: Found dependent: {08e74372-83f2-4594-833b-e924b418b360}, name: My Test Application In the install scenario, I chose to install msi2 and NOT msi1. My bundle code looks like: <Bundle Name="My Test Application" Version="1.0.0.0" Manufacturer="Bryan" UpgradeCode="CC2A383C-751A-43B8-90BF-A250F7BC2863"> <Chain> <PackageGroupRef Id='Netfx4Full' /> <MsiPackage Id="DummyInstallationPackageId3" SourceFile="msi1.msi" ForcePerMachine="yes" InstallCondition="var1 = 1" > </MsiPackage> <MsiPackage SourceFile="msi2.msi" Vital="yes" Cache="yes" Visible="no" ForcePerMachine="yes" InstallCondition="var2 = 2" > </MsiPackage> </Chain> My OnDetectPackageComplete() looks like: private void OnDetectPackageComplete(object sender, DetectPackageCompleteEventArgs e) { if (e.PackageId == "DummyInstallationPackageId3" ) { if (e.State == PackageState.Absent) InstallEnabled = true; else if (e.State == PackageState.Present) UninstallEnabled = true; } } What should I do so that the burn bundle is freely able to uninstall the msi which the user selected at the time of install. Besides, If I select both msi to install, then uninstall is working fine. IMO, there is some problem b/w the relation of bundle and the 2 msi. Please help me as I am stuck with this problem.

• JSF: How to get the selected item from selectOneMenu if its rendering is dynamic?

  - by Dzmitry Zhaleznichenka

  At my view I have two menus that I want to make dependent, namely, if first menu holds values "render second menu" and "don't render second menu", I want second menu to be rendered only if user selects "render second menu" option in the first menu. After second menu renders at the same page as the first one, user has to select current item from it, fill another fields and submit the form to store values in database. Both the lists of options are static, they are obtained from the database once and stay the same. My problem is I always get null as a value of the selected item from second menu. How to get a proper value? The sample code of view that holds problematic elements is: <h:selectOneMenu id="renderSecond" value="#{Bean.renderSecondValue}" valueChangeListener="#{Bean.updateDependentMenus}" immediate="true" onchange="this.form.submit();" > <f:selectItems value="#{Bean.typesOfRendering}" /> </h:selectOneMenu><br /> <h:selectOneMenu id="iWillReturnYouZeroAnyway" value="#{Bean.currentItem}" rendered="#{Bean.rendered}" > <f:selectItems value="#{Bean.items}" /> </h:selectOneMenu><br /> <h:commandButton action="#{Bean.store}" value="#Store" /> However, if I remove "rendered" attribute from the second menu, everything works properly, except for displaying the menu for all the time that I try to prevent, so I suggest the problem is in behavior of dynamic rendering. The initial value of isRendered is false because the default item in first menu is "don't render second menu". When I change value in first menu and update isRendered with valueChangeListener, the second menu displays but it doesn't initialize currentItem while submitting. Some code from my backing bean is below: public void updateDependentMenus(ValueChangeEvent value) { String newValue = (String) value.getNewValue(); if ("render second menu" == newValue){ isRendered = true; } else { isRendered = false; } } public String store(){ System.out.println(currentItem); return "stored"; }

• Submitting a multidimensional array via POST with php

  - by Fireflight

  I have a php form that has a known number of columns (ex. top diameter, bottom diameter, fabric, colour, quantity), but has an unknown number of rows, as users can add rows as they need. I've discovered how to take each of the fields(columns) and place them into an array of their own. <input name="topdiameter['+current+']" type="text" id="topdiameter'+current+'" size="5" /> <input name="bottomdiameter['+current+']" type="text" id="bottomdiameter'+current+'" size="5" /> So what I end up with in the HTML is: <tr> <td><input name="topdiameter[0]" type="text" id="topdiameter0" size="5" /></td> <td><input name="bottomdiameter[0]" type="text" id="bottomdiameter0" size="5" /></td> </tr> <tr> <td><input name="topdiameter[1]" type="text" id="topdiameter0" size="5" /></td> <td><input name="bottomdiameter[1]" type="text" id="bottomdiameter0" size="5" /></td> </tr> ...and so on. What I would like to do now is take all the rows and columns put them into a multidimensional array and email the contents of that to the client (preferably in a nicely formatted table). I haven't been able to really comprehend how to combine all those inputs and selects into a nice array. At this point, I'm going to have to try to use several 1D arrays, although I have the idea that using a single 2D array would be a better practice than using several 1D arrays.

• JSF: SelectOneRadio shortcuts for options

  - by pakore

  I have the following h:selectOneRadio: <h:selectOneRadio style="text-align:left" layout="pageDirection" id="#{prefix}_rating" value="#{examinationPanel.tempResult}" > <f:selectItems value="#{examinationPanel.options}"></f:selectItems> </h:selectOneRadio> And then the backing bean is loading the options based on some userpreferences: public List<SelectItem> loadOptions (Set<ResultEnum> possibleResults){ messages =ResourceBundle.getBundle("com.eyeprevent.resources.Messages",FacesContext.getCurrentInstance().getViewRoot().getLocale()); List<SelectItem> options = new ArrayList<SelectItem>(); for(ResultEnum result:possibleResults){ SelectItem option = new SelectItem(result,messages.getString(result.name())); options.add(option); } return options; } How can I define shortcuts for the options in the radio group? por example typing "1" selects the first option, typing "2" the second, etc... Thanks in advance! ps. I'm using Jsf 1.2, Richfaces, Primefaces and Facelets.

• Opening a View with a Table without a NavigationController

  - by Ken

  Hiya, I'm pretty new to developing with Cocoa Touch/XCode and I came across a problem. I'm making a sort of RSS reader for a newssite and I have 5 views of tables navigated with 5 tabs in a TabBarController. If someone selects a newsitem I want another view to open showing the complete newsitem. My problem is that it won't work. This is my code: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection(NSInteger)section{ return [[[self rssParser]rssItems]count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:@"rssItemCell"]; if(nil == cell){ cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"rssItemCell"]autorelease]; } cell.textLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]title]; cell.detailTextLabel.text = [[[[self rssParser]rssItems]objectAtIndex:indexPath.row]description]; cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [[self appDelegate] setCurrentlySelectedBlogItem:[[[self rssParser]rssItems]objectAtIndex:indexPath.row]]; [self.appDelegate loadNewsDetails]; } And it calls this method in my delegate: -(void)loadNewsDetails{ [[self rootController]pushViewController:detailController animated:YES]; } Please tell me what I'm doing wrong. BTW I do not want to use a NavigationController, just the tabbar I'm using. Thanks in advance, Ken

• LINQ2SQL - Binding result to a grid - want changes to be reflected without re-binding?

  - by Isaac

  Hello, I have a grid (DevExpress XtraGrid, if that matters) which is bound to a LINQ to SQL Entity property. gridItems.DataSource = purchaseOrder.PendingItemsGrouped; Well, the grid is being displayed properly,and I can see the purchase items that are pending. The problem arises when purchaseOrder.PendingItemsGrouped gets changed ... once that happens, the grid does not reflect the changes. The exact procedure is as following: The user selects a row from the grid, inserts a serial number on a specific textbox, and then hits enter effectively receiving this item from the purchase order, and inserting it into stock. inventoryWorker.AddItemToStock( userSelectedItem, serialNumber ); The item gets properly inserted to the inventory, but the grid still shows the item as if it is still awaiting it to be received. How do I solve this problem? Do I really need to re-bind the grid so the changes can be reflected? I even tried instead of: gridItems.DataSource = ...; This: gridItems.DataBindings.Add( new Binding( "DataSource", purchase, "PendingItemsGrouped" ) ); But couldn't solve the problem. Thank you very much for your time, Isaac. OBS: Re-Binding the Grid works, but my question is ... is that even the proper way of doing things? I feel like I'm miles off the right track.
