  • SQL Query Not Functioning - No Error Message

    - by gamerzfuse
    // Write the data to the database $query = "INSERT INTO staff (name, lastname, username, password, position, department, birthmonth, birthday, birthyear, location, phone, email, street, city, state, country, zip, tags, photo) VALUES ('$name', '$lastname', '$username', '$password', '$position', '$department', '$birthmonth', '$birthday', '$birthyear', '$location', '$phone', '$email', '$street', '$city', '$state', '$country', '$zip', '$tags', '$photo')"; mysql_query($query); var_dump($query); echo '<p>' . $name . ' has been added to the Employee Directory.</p>'; if (!$query) { die('Invalid query: ' . mysql_error()); } Can someone tell me why the above code produced: string(332) "INSERT INTO staff (name, lastname, username, password, position, department, birthmonth, birthday, birthyear, location, phone, email, street, city, state, country, zip, tags, photo) VALUES ('Craig', 'Hooghiem', 'sdf', 'sdf', 'sdf', 'sdf', '01', '01', 'sdf', 'sdf', '', 'sdf', 'sdf', 'sd', 'sdf', 'sdf', 'sd', 'sdg', 'leftround.gif')" Craig has been added to the Employee Directory. But does not actually add anything into the database table "staff" ? I must be missing something obvious here.

  • How to recursively serialize an object using reflection ?

    - by Tony
    I want to navigate to the N-th level of an object, and serialize it's properties in String format. For Example: class Animal { public String name; public int weight; public Animal friend; public Set<Animal> children = new HashSet<Animal>() ; } should be serialized like this: {name:"Monkey", weight:200, friend:{name:"Monkey Friend",weight:300 ,children:{...if has children}}, children:{name:"MonkeyChild1",weight:100,children:{... recursively nested}} } And you may probably notice that it is similar to serializing an object to json. I know there're many libs can do this, can you give me some instructive ideas on how to write this?

  • Running multiple instances of tomcat in eclipse WTP

    - by lisak
    Hey, SCENARIO: 10 CATALINA_BASEs with own configuration (always the same port numbers 8080, but 10 different IP/hostnames on one host via virtual IPs). created a server in WTP and pick "Use the custom location" option in the server configuration in eclipse. New configuration files are created in workspace/Server/server-name-config/ Set up the server path and deploy path for my catalina base (not the internal .metadata one) After I started it, the new configuration files overwrote the original catalina-base/conf files I had there - I was glad, it should be like this but after I made changes in the eclipse config files workspace/Server/server-name-config/ and restarted the server, the changes didn't appeared in the original files in CATALINA_BASE/conf What the hell is that ? So I set the CATALINA_BASE/conf/server.xml to fault configuration and restarted tomcat from eclipse and it worked ! it took the configuration from /Server/server-name-config/server.xml Then I deleted CATALINA_BASE/conf/server.xml and it said that there is no server.xml in catalina base ! How is it possible ? I don't understand why eclipse WTP developers made so tight integration. There should by just symbolic links in /Server/server-name-config/ pointing to CATALINA_BASE/conf/ ... now there is a weird system which is totally unpredictable. The changes in /Server/server-name-config/ are not reflected in CATALINA_BASE/conf ... from where the standard bootstrap.jar or other catalina classloaders and classes build server, engine and other objects with particular setting. Moreover the CATALINA_BASEs could be used outside eclipse then. The second problem, I'm setting up various things in CATALINA_BASE/bin/startup.sh and setenv.sh which is easy cause I can use bash for it. Is then modifying VM parameters in the "Open launch configuration" settings the only way how to do it in eclipse ? Sorry for such a huge pile of questions, but I'm annoyed by the fact that it is much better to not use eclipse WTP for this because it is very poorly designed and it's a shame because this would spare me a lot of time. And using the internal .metadata/ instances it's even more terrifying way that the one I described.

  • Tomcat6 MySql JDBC Datasource configuration

    - by Bob
    Hi, I've always used Spring's dependency injection to get datasource objects and use them in my DAOs, but now, I have to write an app without that. With Spring I can write something like this: <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://127.0.0.1/app?characterEncoding=UTF-8" /> <property name="username" value="u" /> <property name="password" value="p" /> </bean> But how can I use datasource in my DAOs without Spring or anything? I'm using servlets and JSPs only. Performance is very important factor. Thanks in advance!

  • jQuery JSON encode set of input values

    - by gurun8
    I need tp serialize a group of input elements but I can't for the life of me figure out this simple task. I can successfully iterate through the targeted inputs using: $("#tr_Features :input").each(function() { ... } Here's my code, that doesn't work: var features = new Array(); $("#tr_Features :input").each(function() { features += {$(this).attr("name"): $(this).val()}; } Serializing the entire form won't give me what I need. The form has much more than this subset of inputs. This seems like it should be a pretty straightforward task but apparently programming late into a Friday afternoon isn't a good thing. If it's helpful, here's the form inputs I'm targeting: <table cellspacing="0" border="0" id="TblGrid_list" class="EditTable" cellpading="0"> <tbody><tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Cable Family</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:8" name="feature_id:8"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Material</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:9" name="feature_id:9"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Thread Size</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:10" name="feature_id:10"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Attachment Style</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:11" name="feature_id:11"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Feature</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:12" name="feature_id:12"></td> </tr> <tr id="tr_Features" class="FormData" rowpos="1"> <td class="CaptionTD ui-widget-content">Comments</td> <td id="td_Features" class="DataTD ui-widget-content" style="white-space: pre;">&nbsp;<input type="text" value="" id="feature_id:13" name="feature_id:13"></td> </tr> </tbody></table>

  • how can I write a schema that produce an unordered xml with extension

    - by ekeren
    In the following schema I am trying to make an unordered xml that extends simpleConfigurationObject: <xs:complexType name="forTestingConfigurationObjectCreator"> <xs:complexContent> <xs:extension base="simpleConfigurationObject"> <xs:all> <xs:element name="a" type="xs:string"/> <xs:element name="b" type="xs:string" minOccurs="0"/> </xs:all> </xs:extension> </xs:complexContent> </xs:complexType> <xs:complexType name="simpleConfigurationObject"> <xs:all> <xs:element name="base" type="xs:string" minOccurs="0"/> </xs:all> </xs:complexType> But I get the following error on the xs:all "all is not the only particle in the group, or is being used as an extension" (which is correct) Off-course if put the base element inside the xs:all and not use xs:extension at all I will get an unordered schema restriction. (but that is not what I want) The question is: how can I produce unordered schema with the extension? Thanks

  • jQuery Autocomplete Json Ajax cross browser issue with Google Search Appliance

    - by skyfoot
    I am implementing a jquery autocomplete on a search form and am getting the suggestions from the Google Search Appliance Autocomple suggestions service which returns a result set in json. What I am trying to do is go off to the GSA to get suggestions when the user types something in the search box. The url to get the json suggestions is as follows: http://gsaurl/suggest?q=<query>&max=10&site=default_site&client=default_frontend&access=p&format=rich The json which is returned is as follows: { "query":"re", "results": [ {"name":"red", "type":"suggest"}, {"name":"read", "type":"suggest"}] } The jQuery autocomplete code is as follows: $(#q).autocomplete(searchUrl, { width: 320, dataType: 'json', highlight: false, scroll: true, scrollHeight: 300, parse: function(data) { var array = new Array(); for(var i=0;i<data.results.length;i++) { array[i] = { data: data.results[i], value: data.results[i].name, result: data.results[i].name }; } return array; }, formatItem: function(row) { return row.name; } }); This works in IE but fails in firefox as the data returned in the parse function is null. Any ideas why this would be the case? Workaround I created an aspx page to call the GSA suggest service and to return the json from the suggest service. Using this page as a proxy and setting it as the url in the jQuery autocomplete worked in both IE and FireFox.

  • Flash video playing on top of everything else in IE7

    - by Brett
    Hi everyone, I've been spending hours now reading up on IE7's issue with rendering Flash content on top of other elements, particularly navigation menus (this is often a problem with dropdown menus and Flash ad banners, for example). I've tried a few of the suggested solutions but none have worked for me so far. I'll do my best to explain the circumstances, and would appreciate any advice in the matter! Update At Mercator's request, I am providing a large code-sample to assist in any advice you might have. Consider the HTML below: <body> <div id="page-wrap"> <div id="content-wrap"> <div id="main"> <h1>Page Title</h1> <p>Paragraph text before video.</p> <div class="video-container"> <script type="text/javascript"> AC_FL_RunContent('id','player','name','player','width','480','height','294','src','player','allowscriptaccess','always','allowfullscreen','true','flashvars','file=mp4/VIDEO_FILE.mp4','movie','player' ); //end AC code </script> <noscript> <object id="player" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" name="player" width="480" height="294"> <param name="wmode" value="transparent" /> <param name="movie" value="player.swf" /> <param name="allowfullscreen" value="true" /> <param name="allowscriptaccess" value="always" /> <param name="flashvars" value="file=mp4/VIDEO_FILE.mp4" /> <embed wmode="transparent" type="application/x-shockwave-flash" id="player2" name="player2" src="player.swf" width="480" height="294" allowscriptaccess="always" allowfullscreen="true" flashvars="file=mp4/VIDEO_FILE.mp4" ></embed> </object> </noscript> </div> <p>Paragraph after video.</p> </div><!-- end main --> <div id="subContent"> <p>Sub-content.</p> </div><!-- end subContent --> <div id="content-clear"></div> </div><!-- end content-wrap --> </div><!-- end page-wrap --> <div id="footpanel"> <ul id="mainpanel"> <li id="panel-link"><a href="#"><span class="icon"></span>Panel Link</a> <div class="subpanel"> <h3><span> &ndash; </span>Panel Link</h3> <ul> <li><p>Revealed content</p></li> </ul> </div> </li> </ul> </div> <!-- END footpanel --> </body> Below are the non-presentational CSS selectors that apply to the divs above: body { /*no positioning styles applied */ } #page-wrap { width: 100%; } #content-wrap { width: 960px; margin 0 auto; } #main { float: left; width: 573px; } .video-container { position: relative; width: 480px; z-index: 1; } #sub { float: left; width: 347px; } #content-clear { clear: both; } #foot-panel { position: fixed; width: 94%; bottom: 0; left: 0; z-index: 3000; } ul#main-panel { float: left; } The footpanel uses jQuery-powered flyout menus, if that provides any further context. These menus have z-indexes in the 300X range to appear above the footpanel. The Flash in question is JW player playing a flash video or mp4. Currently, the object and embed tags are inside a container div. My understanding of previous solutions was that the combination of the param changes and the positioning/z-index change on the container div should have resolved the issue. Alas, it is not so. The player resides on top of the footpanel. Other information that may or may not be helpful is that the page is XHTML 1.0 Transitional and that Dreamweaver reports 1 error in the HTML code: <embed> is not in the XHTML 1.0 specification. This fact does not prevent the video from being viewed in any browser tested, and the page still displays correctly in FF. Thanks in advance!

    Hi, I am using jqGrid for my data table solution.

  • jqGrid - how to change title based on colModel sortable property

    - by Greg
    When the mouse hovers over each column I'd like the tooltip to indicate whether that column is sortable. I am able to change the title attribute with something like this: $("#List .ui-th-column").each(function(i) { var isSortable = i % 2; $(this).attr('title', isSortable ? "Not Sortable" : "Click header to sort."); }); I'd like to replace the demo expression 'i % 2' with a check of the colMode's sortable property, but I can't figure out how to get the value of the colModel's sortable property. colModel: [ { name: 'Name', index: 'Name', width: 100, sortable: true }, { name: 'Note', index: 'Note', width: 200, sortable: false } ] I've tried .getGridParam and .getColProp but I don't think the syntax I'm using is correct.

  • Wpf: Loading DataGrid in Groupbox causes Groupbox to be too tall

    - by Rick Make
    I have a GroupBox that contains a stackpanel holding a textbox and a datagrid. When I use the textbox to populate the datagrid. Sometimes I need to load the datagrid with values. What I am noticing is that when the groupbox renders when the datagrid has values that the height of the groupbox is maxed out to the size of its parent container. And when I add a value via the textbox the groupbox snaps back to its proper height. Is there something that I am missing? When the datagrid renders it looks like all the text in the textcolumns render vertically and then snap into place. <StackPanel x:Name="LeftDock" Margin="0" VerticalAlignment="Top" MinHeight="480" Width="650" > <GroupBox x:Name="g_grpBx" Margin="8,8,0,0" Padding="0,10,0,0" MaxWidth="635" MinWidth="612" VerticalAlignment="Top"> <StackPanel x:Name="g_dp" VerticalAlignment="Top"> <local:TextboxControl x:Name="m_txbx" Margin="0" VerticalAlignment="Top" MinWidth="592"/> <local:GoalDataGrid x:Name="goalDataGrid" Height="Auto" MinHeight="25" MinWidth="592" Margin="0" Padding="0" VerticalAlignment="Top"/> </StackPanel> </GroupBox> </StackPanel>

  • What is the best way to update an unattached entity on Entity Framework?

    - by Carlos Loth
    Hi, In my project I have some data classes to retrieve data from the database using the Entity Framework. We called these classes *EntityName*Manager. All of them have a method to retrieve entities from database and they behave most like this: static public EntityA SelectByName(String name) { using (var context = new ApplicationContext()) { var query = from a in context.EntityASet where a.Name == name select a; try { var entityA = query.First(); context.Detach(entityA); return entityA; } catch (InvalidOperationException ex) { throw new DataLayerException( String.Format("The entityA whose name is '{0}' was not found.", name), ex); } } } You can see that I detach the entity before return it to the method caller. So, my question is "what is the best way to create an update method on my *EntityA*Manager class?" I'd like to pass the modified entity as a parameter of the method. But I haven't figured out a way of doing it without going to the database and reload the entity and update its values inside a new context. Any ideas? Thanks in advance, Carlos Loth.

  • How to make a post request with REQUESTS package for Python?

    - by jorrebor
    I am trying to use the toggl api. I use Requests instead of Urllib2 for doing my GETs en POSTS. But i am stuck. payload = { "project":{ "name":"Another Project", "billable":False, "workspace":{ "Name":"jorrebor's workspace", "id":213272 }, "automatically_calculate_estimated_workhours":False } } url = "https://www.toggl.com/api/v6/projects.json" r = requests.post(url, data=json.dumps(payload), auth=HTTPBasicAuth('[email protected]', 'mypassword')) Authentication seems to be fine, but the payload format probably isn't. a curl command with the same parameters: curl -v -u heremytoken:api_token -H "Content-type: application/json" -d "{\"project\":{\"billable\":true,\"workspace\":{\"id\":213272},\"name\":\"Another project\",\"automatically_calculate_estimated_workhours\":false}}" -X POST https://www.toggl.com/api/v6/projects.json does work fine. What wrong with my payload? The response is get is: ["Name can't be blank","Workspace can't be blank"] which leads me to conclude that the authentication works but toggl cannot read my json object.

  • Views performance in MySQL for denormalization

    - by Gianluca Bargelli
    I am currently writing my truly first PHP Application and i would like to know how to project/design/implement MySQL Views properly; In my particular case User data is spread across several tables (as a consequence of Database Normalization) and i was thinking to use a View to group data into one large table: CREATE VIEW `Users_Merged` ( name, surname, email, phone, role ) AS ( SELECT name, surname, email, phone, 'Customer' FROM `Customer` ) UNION ( SELECT name, surname, email, tel, 'Admin' FROM `Administrator` ) UNION ( SELECT name, surname, email, tel, 'Manager' FROM `manager` ); This way i can use the View's data from the PHP app easily but i don't really know how much this can affect performance. For example: SELECT * from `Users_Merged` WHERE role = 'Admin'; Is the right way to filter view's data or should i filter BEFORE creating the view itself? (I need this to have a list of users and the functionality to filter them by role). EDIT Specifically what i'm trying to obtain is Denormalization of three tables into one. Is my solution correct? See Denormalization on wikipedia

  • Vim with Powershell

    - by Kevin Berridge
    I'm using gvim on Windows. In my _vimrc I've added: set shell=powershell.exe set shellcmdflag=-c set shellpipe=> set shellredir=> function! Test() echo system("dir -name") endfunction command! -nargs=0 Test :call Test() If I execute this function (:Test) I see nonsense characters (non number/letter ASCII characters). If I use cmd as the shell, it works (without the -name), so the problem seems to be with getting output from powershell into vim. Interestingly, this works great: :!dir -name As does this: :r !dir -name UPDATE: confirming behavior mentioned by David If you execute the set commands mentioned above in the _vimrc, :Test outputs nonsense. However, if you execute them directly in vim instead of in the _vimrc, :Test works as expected. Also, I've tried using iconv in case it was an encoding problem: :echo iconv( system("dir -name"), "unicode", &enc ) But this didn't make any difference. I could be using the wrong encoding types though. Anyone know how to make this work?

  • struct assignment operator on arrays

    - by Django fan
    Suppose I defined a structure like this: struct person { char name [10]; int age; }; and declared two person variables: person Bob; person John; where Bob.name = "Bob", Bob.age = 30 and John.name = "John",John.age = 25. and I called Bob = John; struct person would do a Memberwise assignment and assign Johns's member values to Bob's. But arrays can't assign to arrays, so how does the assignment of the "name" array work?

  • How to properly combine two files in XAML in Microsoft Blend?

    - by MartyIX
    Hello, I have a test project with the file MainWindow.xaml with the content: <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" xmlns:view="clr-namespace:Sokoban.View;assembly=Solvers" Title="Window1" Height="300" Width="300" Loaded="Window_Loaded"> <ad:DockingManager x:Name="dockingManager"> <ad:ResizingPanel Orientation="Vertical"> <view:Solvers x:Name="solvers" diag:PresentationTraceSources.TraceLevel="High" /> <!-- LINE BELOW DEMONSTRATES WORKING CODE INSTEAD OF LINE ABOVE --> <!--<ad:DocumentPane Name="GamesDocumentPane" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <ad:DockableContent x:Name="classesContent" Title="Classes"> <TextBlock>test</TextBlock> </ad:DockableContent> </ad:DocumentPane>--> </ad:ResizingPanel> </ad:DockingManager> </Window> and in another project I have the file Solvers.xaml: <ad:DocumentPane x:Class="Sokoban.View.Solvers" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:ad="clr-namespace:AvalonDock;assembly=AvalonDock" xmlns:diag="clr-namespace:System.Diagnostics;assembly=WindowsBase" Name="GamesDocumentPane" HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> </ad:DocumentPane> When I open my Visual Studio solution in Microsoft Blend 4 then I see the error: InvalidOperationException: DocumentPane must be put under a DockingManager! when I open either MainWindow.xaml or Solvers.xaml. It is all right in Solvers.xaml because there really is no DockingManager but MainWindow.xaml should work, shouldn't it? How to solve the problem? Note: It seems to me that the files are processed separately and because the file Solvers.xaml contains the error the MainWindow.xaml file also contains the very same error. Note 2: XAML files use AvalonDock library Is there a way how to say that Solvers.xaml is only an extension of another file? Thank you for any help!

  • Using AsyncTask to display data in ListView, but onPostExecute not being called

    - by sumisu
    I made a simple AsyncTask class to display data in ListView with the help of this stackoverflow question. But the AsyncTask onPostExecute is not being called. This is my code: public class Start extends SherlockActivity { // JSON Node names private static final String TAG_ID = "id"; private static final String TAG_NAME = "name"; // category JSONArray JSONArray category = null; private ListView lv; @Override public void onCreate(Bundle savedInstanceState) { setTheme(SampleList.THEME); //Used for theme switching in samples super.onCreate(savedInstanceState); setContentView(R.layout.test); new MyAsyncTask().execute("http://...."); // Launching new screen on Selecting Single ListItem lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // getting values from selected ListItem String name = ((TextView) view.findViewById(R.id.name)).getText().toString(); String cost = ((TextView) view.findViewById(R.id.mail)).getText().toString(); // Starting new intent Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class); in.putExtra("categoryname", name); System.out.println(cost); in.putExtra("categoryid", cost); startActivity(in); } }); } public class MyAsyncTask extends AsyncTask<String, Void, ArrayList<HashMap<String, String>> > { // Hashmap for ListView ArrayList<HashMap<String, String>> contactList = new ArrayList<HashMap<String, String>>(); @Override protected ArrayList<HashMap<String, String>> doInBackground(String... params) { // Creating JSON Parser instance JSONParser jParser = new JSONParser(); // getting JSON string from URL category = jParser.getJSONArrayFromUrl(params[0]); try { // looping through All Contacts for(int i = 0; i < category.length(); i++){ JSONObject c = category.getJSONObject(i); // Storing each json item in variable String id = c.getString(TAG_ID); String name = c.getString(TAG_NAME); // creating new HashMap HashMap<String, String> map = new HashMap<String, String>(); // adding each child node to HashMap key => value map.put(TAG_ID, id); map.put(TAG_NAME, name); // adding HashList to ArrayList contactList.add(map); } } catch (JSONException e) { Log.e("log_tag", "Error parsing data "+e.toString()); } return contactList; } @Override protected void onPostExecute(ArrayList<HashMap<String, String>> result) { ListAdapter adapter = new SimpleAdapter(Start.this, result , R.layout.list_item, new String[] { TAG_NAME, TAG_ID }, new int[] { R.id.name, R.id.mail }); // selecting single ListView item lv = (ListView) findViewById(R.id.ListView); lv.setAdapter(adapter); } } } Eclipse: 11-25 11:40:31.896: E/AndroidRuntime(917): java.lang.RuntimeException: Unable to start activity ComponentInfo{de.essentials/de.main.Start}: java.lang.NullPointerException
