  • Mode specific key bindings

    - by rejeep
    Hey, I have a minor mode that also comes with a global mode. The mode have some key bindings and I want the user to have the posibility to specify what bindings should work for each mode. (my-minor-mode-bindings-for-mode 'some-mode '(key1 key2 ...)) (my-minor-mode-bindings-for-mode 'some-other-mode '(key3 key4 ...)) So I need some kind of mode/buffer-local key map. Buffer local is a bit problematic since the user can change the major mode. I have tried some solutions of which neither works any good. Bind all possible keys always and when the user types the key, check if the key should be active in that mode. Execute action if true, otherwise fall back. Like the previous case only that no keys are bound. Instead I use a pre command hook and check if the key pressed should do anything. For each buffer update (whatever that means), run a function that first clears the key map and then updates it with the bindings for that particular mode. I have tried these approaches and I found problems with all of them. Do you know of any good way to solve this? Thanks!

  • Alternative to array_shift function

    - by SoLoGHoST
    Ok, I need keys to be preserved within this array and I just want to shift the 1st element from this array. Actually I know that the first key of this array will always be 1 when I do this: // Sort it by 1st group and 1st layout. ksort($disabled_sections); foreach($disabled_sections as &$grouplayout) ksort($grouplayout); Basically I'd rather not have to ksort it in order to grab this array where the key = 1. And, honestly, I'm not a big fan of array_shift, it just takes to long IMO. Is there another way. Perhaps a way to extract the entire array where $disabled_sections[1] is found without having to do a foreach and sorting it, and array_shift. I just wanna add $disabled[1] to a different array and remove it from this array altogether. While keeping both arrays keys structured the way they are. Technically, it would even be fine to do this: $array = array(); $array = $disabled_sections[1]; But it needs to remove it from $disabled_sections. Can I use something like this approach... $array = array(); $array = $disabled_sections[1]; $disabled_sections -= $disabled_sections[1]; Is something like the above even possible?? Thanks.

  • Filter entities that match all pairs

    - by Jon
    I have an entity (let's say Person) with a set of arbitrary attributes with a known subset of values. I need to search for all of these entities that match all my filter conditions. For example, my table structures look like this: Person: id | name 1 | John Doe 2 | Jane Roe 3 | John Smith Attribute: id | attr_name 1 | Sex 2 | Eye Color ValidValue: id | attr_id | value_name 1 | 1 | Male 2 | 1 | Female 3 | 2 | Blue 4 | 2 | Green 5 | 2 | Brown PersonAttributes id | person_id | attr_id | value_id 1 | 1 | 1 | 1 2 | 1 | 2 | 3 3 | 2 | 1 | 2 4 | 2 | 2 | 4 5 | 3 | 1 | 1 6 | 3 | 2 | 4 In JPA, I have entities built for all of these tables. What I'd like to do is perform a search for all entities matching a given set of attribute-value pairs. For instance, I'd like to be able to find all males (John Doe and John Smith), all people with green eyes (Jane Roe or John Smith), or all females with green eyes (Jane Roe). I see that I can already take advantage of the fact that I only really need to match on value_id, since that's already unique and tied to the attr_id. But where can I go from there?

  • Why can't I set boolean columns with update?

    - by Benjamin Oakes
    I'm making a user administration page. For the system I'm creating, users need to be approved. Sometimes, there will be many users to approve, so I'd like to make that easy. I'm storing this as a boolean column called approved. I remembered the Edit Multiple Individually Railscast and thought it would be a great fit. However, I'm running into problems which I traced back to ActiveRecord::Base#update. update works fine in this example: >> User.all.map(&:username) => ["ben", "fred"] >> h = {"1"=>{'username'=>'benjamin'}, "2"=>{"username"=>'frederick'}} => {"1"=>{"username"=>"benjamin"}, "2"=>{"username"=>"frederick"}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:username) => ["benjamin", "frederick"] But not this one: >> User.all.map(&:approved) => [true, nil] >> h = {"1"=>{'approved'=>'1'}, "2"=>{'approved'=>'1'}} >> User.update(h.keys, h.values) => ... >> User.all.map(&:approved) => [true, nil] Chaging from '1' to true didn't make a difference when I tested. What am I doing wrong?

  • WPF Designer has bug with parsing generic control with overrided property

    - by Ivan Laktyunkin
    I've created a generic lookless control with virtual property: public abstract class TestControlBase<TValue> : Control { public static readonly DependencyProperty ValueProperty; static TestControlBase() { ValueProperty = DependencyProperty.Register("Value", typeof(TValue), typeof(TestControlBase<TValue>)); } protected TestControlBase() { Focusable = false; Value = default(TValue); } public virtual TValue Value { get { return (TValue)GetValue(ValueProperty); } set { SetValue(ValueProperty, value); } } } Then I've made a control derived from it and overrided Value property: public class TestControl : TestControlBase<int> { public override int Value { get { return base.Value; } set { base.Value = value; } } } So I use it in a Window XAML: <TestControls:TestControl /> When I open window in designer all is OK, but when I put mouse cursor to this line, or to this control in designer I receive exception: Exception has been thrown by the target of an invocation. at System.RuntimeMethodHandle._InvokeMethodFast(Object target, Object[] arguments, SignatureStruct& sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.RuntimeMethodHandle.InvokeMethodFast(Object target, Object[] arguments, Signature sig, MethodAttributes methodAttributes, RuntimeTypeHandle typeOwner) at System.Reflection.RuntimeMethodInfo.Invoke(Object obj, BindingFlags invokeAttr, Binder binder, Object[] parameters, CultureInfo culture, Boolean skipVisibilityChecks) at System.Delegate.DynamicInvokeImpl(Object[] args) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) Ambiguous match found. at System.RuntimeType.GetPropertyImpl(String name, BindingFlags bindingAttr, Binder binder, Type returnType, Type[] types, ParameterModifier[] modifiers) at System.Type.GetProperty(String name) at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsDirect() at MS.Internal.ComponentModel.DependencyPropertyKind.get_IsAttached() at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties(Attribute[] attributes) at MS.Internal.ComponentModel.APCustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.TypeDescriptionNode.DefaultExtendedTypeDescriptor.System.ComponentModel.ICustomTypeDescriptor.GetProperties() at System.ComponentModel.TypeDescriptor.GetPropertiesImpl(Object component, Attribute[] attributes, Boolean noCustomTypeDesc, Boolean noAttributes) at System.ComponentModel.TypeDescriptor.GetProperties(Object component) at MS.Internal.Model.ModelPropertyCollectionImpl.GetProperties(String propertyNameHint) at MS.Internal.Model.ModelPropertyCollectionImpl.<GetEnumerator>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.Model.ModelPropertyMerger.<GetFirstProperties>d__0.MoveNext() at MS.Internal.Designer.PropertyEditing.PropertyInspector.UpdateCategories(Selection selection) at MS.Internal.Designer.PropertyEditing.PropertyInspector.OnSelectionChangedIdle() Who know this problem?

  • Eclipse says I don't implement Enumeration, but I do

    - by Harm De Weirdt
    Goodmorning everybody, I'm having a little problem with a project for school. We are told to make an Iterator that implements Enumeration over a Hashmap. So i made this Enumeration: public Enumeration<Object> getEnumeration() { return new Enumeration<Object>() { private int itemsDone = 0; Collection<Long> keysCollection = getContent().keySet(); Long [] keys = keysCollection.toArray(new Long[keysCollection.size()]); @Override public boolean hasMoreElements() { if(itemsDone < getContent().size() +1 ) { return true; }else { return false; } } @Override public Object nextElement() { return getContent().get(keys[itemsDone++]); } }; } This goes in my Backpack class public class Backpack extends Item implements Carrier, Enumeration<Object>{ The hashmap is returned by getContent(). The problem now is that eclipse keeps telling me I havent implemented the methods from Enumeration. If I use the quick fix it just adds the hasMoreElements() and nextElement() dummy methods in my class. Somehow it doesn't see these methods in the inner class.. Can anyone help me please? Any help is appreciated.

  • Single Sign On for WebServices, WCS, WFS, WMS (Geoserver), etc.

    - by lajuette
    I'm trying to implement a Single Sign On (SSO) for a web application. Maybe you can help me find a proper solution, give me a direction or tell me, that solutions already exist. The scenario: A GeoExt (ExtJS for geodata/map based apps) webapp (JavaScript only) has a login form to let the user authenticate himself. The authentication is not implemented yet, so i'm flexible with respect to that. After authenticating to the main webapp the user indirectly accesses multiple 3rd-party services like WebServices, GeoServer WFS, Google Maps, etc. These services might require additional authentication like credentials or keys. We are (so far) not talking about additional login screens, just some kind of "machine to machine"-authentication. The main problem: I'm unable to modify the 3rd party services (e.g. Google) to add a SSO mechanism. I'd like to have a solution that allows the user to log in once to have access to all the services required. My first idea was a repository that stores all the required credentials or keys. The user logs in and can retrieve all required information to acces sthe other services. Does anybody know of existing implementations, papers, maybe implementations of such services? Other requirements: The communication between the JS application and the repository must be secure. The credentials must be stored in a secure manner. But the JS app must be able to use them to access the services (no chance to store a decryption key in a JS-app securely, eh? *g).

  • problems with build params for accepts_nested_attributes_for

    - by holden
    I'm trying to add the user_id to a nested attribute that gets built by a parent controller but it doesn't seem to have the desired effect? Ie. I have a model called Place.rb which accepts_nested_attributes_for :reviews The nested attribute works fine and I build it inside the Places controller like so... @review = @place.reviews.build(:user_id => current_user.id) I was previously adding the user thru the form, but would like to do it thru the controller so that it only adds the user_id on creation, as it might get updated by someone else and i don't want the update changing the user_id... old way which works: <%= e.label :content, "Review" %><br /> <%= e.text_area :content, :rows => 20, :class => 'jquery_ckeditor' %><br /> <%= e.hidden_field :user_id, :value => current_user.id %> but thru the controller the build method with options has no effect? Any ideas? Can I not do this thru the build?

  • Kohana 3 ORM: How to get data from pivot table? and all other tables for that matter

    - by zenna
    I am trying to use ORM to access data stored, in three mysql tables 'users', 'items', and a pivot table for the many-many relationship: 'user_item' I followed the guidance from http://stackoverflow.com/questions/1946357/kohana-3-orm-read-additional-columns-in-pivot-tables and tried $user = ORM::factory('user',1); $user->items->find_all(); $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)); if ($user_item->loaded()) { foreach ($user_item as $pivot) { print_r($pivot); } } But I get the SQL error: "Unknown column 'user_item.id' in 'order clause' [ SELECT user_item.* FROM user_item WHERE user_id = '1' AND item_id = '' ORDER BY user_item.id ASC LIMIT 1 ]" Which is clearly erroneous because Kohana is trying to order the elements by a column which doesn't exist: user_item.id. This id doesnt exist because the primary keys of this pivot table are the foreign keys of the two other tables, 'users' and 'items'. Trying to use: $user_item = ORM::factory('user_item', array('user_id' => $user, 'item_id' => $user->items)) ->order_by('item_id', 'ASC'); Makes no difference, as it seems the order_by() or any sql queries are ignored if the second argument of the factory is given. Another obvious error with that query is that the item_id = '', when it should contain all the elements. So my question is how can I get access to the data stored in the pivot table, and actually how can I get access to the all items held by a particular user as I even had problems with that? Thanks

  • Is it practical to program with your feet?

    - by bmm
    Has anyone tried using foot pedals in addition to the traditional keyboard and mouse combo to improve your effectiveness in the editor? Any actual experiences out there? Does it work, or is it just for carpal tunnel relief? I found one blog entry from a programmer who actually tried it: So now I can type using my feet for most of the modifier keys. I am using the pedals as I type this. I am still getting used to them, but the burning in my left wrist has definitely reduced. I think I can also type a little faster, but I am too lazy to do the speed tests with and without the pedals to verify this. On the negative side: Working out where to put your feet when you aren’t typing can be a little awkward. The pedals tend to move around the carpet, despite being metal and quite heavy. Some small spikes might have helped. Although the travel on the pedals is small, they are surprisingly stiff. Another programmer's experience: Anybody with hand pain must get foot pedals, since they can remove a tremendous load from your hands. I have two foot pedals, and use one for the SHIFT key, and the other for the CONTROL key. (I still type META by hand.) I have found that in the process of using the Emacs text editor to compose computer programs, I tend to use the SHIFT, CONTROL and META keys constantly, and it is easy to remove most of this load from one's hands.

  • Need help choosing database server

    - by The Pretender
    Good day everyone. Recently I was given a task to develop an application to automate some aspects of stocks trading. While working on initial architecture, the database dilemma emerged. What I need is a fast database engine which can process huge amounts of data coming in very fast. I'm fairly experienced in general programming, but I never faced a task of developing a high-load database architecture. I developed a simple MSSQL database schema with several many-to-many relationships during one of my projects, but that's it. What I'm looking for is some advice on choosing the most suitable database engine and some pointers to various manuals or books which describe high-load database development. Specifics of the project are as follows: OS: Windows NT family (Server 2008 / 7) Primary platform: .NET with C# Database structure: one table to hold primary items and two or three tables with foreign keys to the first table to hold additional information. Database SELECT requirements: Need super-fast selection by foreign keys and by combination of foreign key and one of the columns (presumably DATETIME) Database INSERT requirements: The faster the better :) If there'll be significant performance gain, some parts can be written in C++ with managed interfaces to the rest of the system. So once again: given all that stuff I just typed, please give me some advice on what the best database for my project is. Links or references to some manuals and books on the subject are also greatly appreciated. EDIT: I'll need to insert 3-5 rows in 2 tables approximately once in 30-50 milliseconds and I'll need to do SELECT with 0-2 WHERE clauses queries with similar rate.

  • I need my BizTalk map to stop converting xml:lang to ns1:lang

    - by Jeremy Stein
    I have a map in BizTalk 2009 that is converting some data into an XML document to be sent on to another system. The target schema includes some elements with xml:lang attributes. BizTalk generates those as ns1:lang. The target system requires that the prefix xml be used. Here is a simplified example to show what BizTalk is doing: sample.xsd <xs:schema targetNamespace="http://example.com/" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:import schemaLocation="common.xsd" namespace="http://www.w3.org/XML/1998/namespace" /> <xs:element name="example"> <xs:complexType> <xs:attribute ref="xml:lang" /> </xs:complexType> </xs:element> </xs:schema> common.xsd <?xml version="1.0" encoding="utf-16"?> <xs:schema xmlns:xml="http://www.w3.org/XML/1998/namespace" targetNamespace="http://www.w3.org/XML/1998/namespace" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:attribute name="lang" type="xs:language" /> </xs:schema> Example of map output <ns0:example xmlns:ns0="http://example.com/" xmlns:ns1="http://www.w3.org/XML/1998/namespace" ns1:lang="en-US" /> Is there some way to convince BizTalk to use the xml prefix?

  • TCL TDom: Looping through Objects

    - by pws5068
    Using TDom, I would like to cycle through a list of objects in the following format: <object> <type>Hardware</type> <name>System Name</name> <description>Basic Description of System.</description> <attributes> <vendor>Dell</vendor> <contract>MM/DD/YY</contract> <supportExpiration>MM/DD/YY</supportExpiration> <location>Building 123</location> <serial>xxx-xxx-xxxx</serial> <mac>some-mac-address</mac> </attributes> </object> <object> <type>Software</type> <name>Second Object</name> ... Then I use TDom to make a list of objects: set dom [dom parse $xml] set doc [$dom documentElement] set nodeList [$doc selectNodes /systems/object] So far I've done this to (theoretically) select every "Object" node from the list. How can I loop through them? Is it just: foreach node $nodeList { For each object, I need to retrieve the association of each attribute. From the example, I need to remember that the "name" is "System Name", "vendor" is "Dell", etc. I'm new to TCL but in other languages I would use an object or an associative list to store these. Is this possible? Can you show me an example of the syntax to select an attribute in this manner?

  • I am using relational division with EAV, but I need to find results in EAV that have some of the cat

    - by NewToDB
    I have two tables: CREATE TABLE EAV ( subscriber_id INT(1) NOT NULL DEFAULT '0', attribute_id CHAR(62) NOT NULL DEFAULT '', attribute_value CHAR(62) NOT NULL DEFAULT '', PRIMARY KEY (subscriber_id,attribute_id) ) INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (1,'color','red') INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (1,'size','xl') INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (1,'garment','shirt') INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (2,'color','red') INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (2,'size','xl') INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (2,'garment','pants') INSERT INTO EAV (subscriber_id, attribute_id, attribute_value) VALUES (3,'garment','pants') CREATE TABLE CRITERIA ( attribute_id CHAR(62) NOT NULL DEFAULT '', attribute_value CHAR(62) NOT NULL DEFAULT '' ) INSERT INTO CRITERIA (attribute_id, attribute_value) VALUES ('color', 'red') INSERT INTO CRITERIA (attribute_id, attribute_value) VALUES ('size', 'xl') To find all subscribers in the EAV that match my criteria, I use relational division: SELECT DISTINCT(subscriber_id) FROM EAV WHERE subscriber_id IN (SELECT E.subscriber_id FROM EAV AS E JOIN CRITERIA AS CR ON E.attribute_id = CR.attribute_id AND E.attribute_value = CR.attribute_value GROUP BY E.subscriber_id HAVING COUNT() = (SELECT COUNT() FROM CRITERIA)) This gives me an unique list of subscribers who have all the criteria. So that means I get back subscriber 1 and 2 since they are looking for the color red and size xl, and that's exactly my criteria. But what if I want to extend this so that I also get subscriber 3 since this subscriber didn't specifically say what color or size they want (ie. there is no entry for attribute 'color' or 'size' in the EAV table for subscriber 3). Given my current design, is there a way I can extend my query to include subscribers that have zero or more of the attributes defined, and if they do have the attribute defined, then it must match the criteria? Or is there a better way to design the table to aid in querying?

  • mysql complex key or + auto increment key (guid)

    - by darko
    Hi, I have not very big db. I am using auto increment primary keys and in my case there is no problem with that. GUID is not necessary. I have a table containing this fields: from_destination to_testination shipper quantity Where the fields 1,2,3 needs to be unique. Also I have second table that for the fields 1,2,3 stores bought quantities per day One to many. from_destination to_destination shipper date reserved_quantity case 1 Is it better to make fields 1,2,3 as primary complex key in the first table and the same fields in the second table to be foreign key First table from_destination | to_destination | primary shipper | quaitity Second table second_id - autoincrement primary from_destination | to_destination | foreign key shipper | date reserved_quantity Case 2 or just to add auto increment filed in the first table and make fields 1,2,3 unique. In the second table there will be one ingeger foreign key pointing to the first table, and one auto increment key for the table. First table first_id - autoincrement primary from_destination | to_destination | unique shipper | quaitity Second table second_id - autoincrement primary first_id - forein date reserved_quantity If so why we need complex keys, when we can have one field auto increment or GUID and all other fields that are candidates for complex key to be unique.

  • Windows Azure ASP.NET MVC Role behaves strangely when redirecting from HTTP to HTTPS

    - by Rinat Abdullin
    Subj. I've got an ASP.NET 2 MVC Worker Role Application, that does not differ much from the default template. When attempting redirect from HTTP to HTTPS (this happens when we access constroller secured by the usual RequireSSL attribute implementation) we get blank page with "Bad Request" message. IntelliTrace shows this: Thrown: "The file '/Views/Home/LogOnUserControl.aspx' does not exist." (System.Web.HttpException) Call stack is really short: [External Code] App_Web_vfahw7gz.dll!ASP.views_shared_site_master.__Render__control1(System.Web.UI.HtmlTextWriter __w = {unknown}, System.Web.UI.Control parameterContainer = {unknown}) [External Code] App_Web_bsbqxr44.dll!ASP.views_home_index_aspx.ProcessRequest(System.Web.HttpContext context = {unknown}) [External Code] User control reference is the usual one in /Views/Shared/Site.Master: <div id="logindisplay"> <% Html.RenderPartial("LogOnUserControl"); %> </div> And partial view LogOnUserControl.ashx is located in Views/Shared (and it is ASHX, not ASPX). Problem shows up, when we try to access site pages, that require auth and redirect. These pages are secured by RequireSSL attribute (Redirect == true): [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = false)] public sealed class RequireSslAttribute : FilterAttribute, IAuthorizationFilter { public bool Redirect { get; set; } // Methods public void OnAuthorization(AuthorizationContext filterContext) { // this get's messy, when we are running custom ports // within the local dev fabric. // hence we disable code in the debug #if !DEBUG if (filterContext == null) { throw new ArgumentNullException("filterContext"); } if (filterContext.HttpContext.Request.IsSecureConnection) return; var canRedirect = string.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase); if (canRedirect && Redirect) { var builder = new UriBuilder { Scheme = "https", Host = filterContext.HttpContext.Request.Url.Host, Path = filterContext.HttpContext.Request.RawUrl }; filterContext.Result = new RedirectResult(builder.ToString()); } else { throw new HttpException(0x193, "Access forbidden.

Does anybody have any idea, what could cause this strange exception and how to get rid of it?

  • Hot to make COM ActiveX object work in IE 64 bit?

    Hi! I have a COM object embeded in ASP.NET page using <object classid="clsid:XXX...">. It works in IE 32 bit, but does not work in IE 64 bit - can't access its functions. There are no error messages, no event logs where I can get some information. The dll is in C#, includes COM visible class, compiled for Any CPU (though I also tried x86), and registered during client installation by executing regasm. This creates registry keys, well everything works fine except for IE 64. I searched internet about the issue or at least some guidlines and didn't find anything. I received an answer on another forum, something about _MERGE_PROXYSTUB (I guess it's preprocessor definition?) and ProxyStubClsid32 registry key, but not very detailed. Well, I searched again, didn't find much, and experimented: rebuilt with _MERGE_PROXYSTUB defined, created ProxyStubClsid32 keys everywhere, but with no result. What can be at least possible solutions or points to look at? Maybe there is a way at least to get the logs about why IE 64 can't access it?

  • Looping through a SimpleXML object, or turning the whole thing into an array.

    - by Coffee Cup
    I'm trying to work out how to iterate though a returned SimpleXML object. I'm using a toolkit called Tarzan AWS, which connects to Amazon Web Services (SimpleDB, S3, EC2, etc). I'm specifically using SimpleDB. I can put data into the Amazon SimpleDB service, and I can get it back. I just don't know how to handle the SimpleXML object that is returned. The Tarzan AWS documentation says this: Look at the response to navigate through the headers and body of the response. Note that this is an object, not an array, and that the body is a SimpleXML object. Here's a sample of the returned SimpleXML object: [body] = SimpleXMLElement Object ( [QueryWithAttributesResult] = SimpleXMLElement Object ( [Item] = Array ( [0] = SimpleXMLElement Object ( [Name] = message12413344443260 [Attribute] = Array ( [0] = SimpleXMLElement Object ( [Name] = active [Value] = 1 ) [1] = SimpleXMLElement Object ( [Name] = user [Value] = john ) [2] = SimpleXMLElement Object ( [Name] = message [Value] = This is a message. ) [3] = SimpleXMLElement Object ( [Name] = time [Value] = 1241334444 ) [4] = SimpleXMLElement Object ( [Name] = id [Value] = 12413344443260 ) [5] = SimpleXMLElement Object ( [Name] = ip [Value] = 10.10.10.1 ) ) ) [1] = SimpleXMLElement Object ( [Name] = message12413346907303 [Attribute] = Array ( [0] = SimpleXMLElement Object ( [Name] = active [Value] = 1 ) [1] = SimpleXMLElement Object ( [Name] = user [Value] = fred ) [2] = SimpleXMLElement Object ( [Name] = message [Value] = This is another message ) [3] = SimpleXMLElement Object ( [Name] = time [Value] = 1241334690 ) [4] = SimpleXMLElement Object ( [Name] = id [Value] = 12413346907303 ) [5] = SimpleXMLElement Object ( [Name] = ip [Value] = 10.10.10.2 ) ) ) ) So what code do I need to get through each of the object items? I'd like to loop through each of them and handle it like a returned mySQL query. For example, I can query SimpleDB and then loop though the SimpleXML so I can display the results on the page. Alternatively, how do you turn the whole shebang into an array? I'm new to SimpleXML, so I apologise if my questions aren't specific enough.

    - by Rohit
    I am creating a comma seperated values of columns specified in dbName attribute of below xml. Now i want to concatenate those columns on the basic of Position attribute. DECLARE @varXML AS XML = '<gridFormat> <column property="FacilityInternalID" dbName="Pname" HeaderText="TAT Health" IsVisible="1" Position="1" /> <column property="FacilityInternalID" dbName="Priority" HeaderText="Priority" IsVisible="1" Position="2" /> <column property="FacilityInternalID" dbName="JobID" HeaderText="Job Number" IsVisible="1" Position="3" /> <column property="FacilityInternalID" dbName="Status" HeaderText="Status" IsVisible="1" Position="6" /> <column property="FacilityInternalID" dbName="name" HeaderText="Customer" IsVisible="1" Position="4" /> <column property="FacilityInternalID" dbName="sname" HeaderText="Facility " IsVisible="1" Position="5" /> </gridFormat>' PRINT @varXML This is the query by which I am generating CSV of columns. I have to use it is select list. SELECT @ColumnsToDisplay = LEFT(MyCsvList, LEN(MyCsvList) - 1) FROM ( SELECT ( SELECT row.value('@property', 'varchar(200)') + ', ' AS [text()] FROM @varXML.nodes('gridFormat/column') AS d ( row ) FOR XML PATH('') ) AS MyCsvList ) AS MyCsvListFinal SET @SQL = 'SELECT ' + @ColumnsToDisplay + ' FROM JobListingDetails' Result should be select Pname,Priority,JobID,name,sname,status FROM JobListingDetails. Please help.

  • Writing XML in different character encodings with Java

    - by Roman Myers
    I am attempting to write an XML library file that can be read again into my program. The file writer code is as follows: XMLBuilder builder = new XMLBuilder(); Document doc = builder.build(bookList); DOMImplementation impl = doc.getImplementation(); DOMImplementationLS implLS = (DOMImplementationLS) impl.getFeature("LS", "3.0"); LSSerializer ser = implLS.createLSSerializer(); String out = ser.writeToString(doc); //System.out.println(out); try{ FileWriter fstream = new FileWriter(location); BufferedWriter outwrite = new BufferedWriter(fstream); outwrite.write(out); outwrite.close(); }catch (Exception e){ } The above code does write an xml document. However, in the XML header, it is an attribute that the file is encoded in UTF-16. when i read in the file, i get the error: "content not allowed in prolog" this error does not occur when the encoding attribute is manually changed to UTF-8. I am trying to get the above code to write an XML document encoded in UTF-8, or successfully parse a UTF-16 file. the code for parsing in is DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); DocumentBuilder loader = factory.newDocumentBuilder(); Document document = loader.parse(filename); the last line returns the error.

  • NHibernate: Mapping multiple classes from a single table row

    - by Michael Kurtz
    I couldn't find an answer to this specific question. I am trying to keep my domain model object-oriented and re-use objects where possible. I am having an issue determining how to provide a mapping to multiple classes from a single row. Let me explain with an example: I have a single table, call it Customer. A customer has several attributes; but, for brevity, assume it has Id, Name, Address, City, State, ZipCode. I would like to create a Customer and Address class that look like this: public class Customer { public virtual long Id {get;set;} public virtual string Name {get;set;} public virtual Address Address {get;set;} } public class Address { public virtual string Address {get;set;} public virtual string City {get;set;} public virtual string State {get;set;} public virtual string ZipCode {get;set;} } What I am having trouble with is determining what the mapping would be for the Address class within the Customer class. There is no Address table and there isn't a "set" of addresses associated with a Customer. I just want a more object-oriented view of the Customer table in code. There are several other tables that have address information in them and it would be nice to have a reusable Address class to deal with them. Addresses are not shared so breaking all addresses into a separate table with foreign keys seems to be overkill and, actually, more painful since I would need foreign keys to multiple tables. Can someone enlighten me on this type of mapping? Please provide an example if you can. Thanks for any insights! -Mike

  • encrypt apache and mysql servers

    - by stormdrain
    I have a question about encrypting disks. I have 2 servers: 1 is apache for web/frontend and it talks to server 2 which is mysql. They are all for intranet only; no external access. I was looking into using PGP or GnuPG to encrypt the disks. I'm not clear, though, as to exactly how this would work. Where would the keys be stored? On the client? On apache? If there is a key on apache to access mysql, does there need to be a key for each user? If so, if key 1 is used to alter some data, would then that data be inaccessible to a user using key 2? And the apache key, would that only be accessible to users with local keys? Is encryption done on the fly? Does it degrade performance? What would be the best approach to encrypt the data on these servers, but have them accessible to users? Thanks!

  • Xpath > How can I select a node based on both its attributes and content?

    - by Andrew Kirk
    Sample XML: <assignments> <assignment id="911990211" section-id="1942268885" item-count="21" sources="foo"> <options> <value name="NumRetakes">4</value> <value name="MultipleResultGrading">6</value> <value name="MaxFeedbackAttempts">-1</value> <value name="ItemTakesBeforeHint">1</value> <value name="TimeAllowed">0</value> </options> </assignment> <assignment id="1425185257" section-id="1505958877" item-count="4" sources="bar"> <options> <value name="NumRetakes">0</value> <value name="MultipleResultGrading">6</value> <value name="MaxFeedbackAttempts">3</value> <value name="ItemTakesBeforeHint">1</value> <value name="TimeAllowed">0</value> </options> </assignment> <assignments> Using XPath, I would like to select all assignments/assignment/options/value nodes where the nodes "name" attribute is "MaxFeedbackAttempts" and the nodes content is "-1". That is to say, I want to return each node that looks like: <value name="MaxFeedbackAttempts">-1</value> I can get each assignments/assignment/options/value node with the specified attribute using: //assignment/options/value[@name="MaxFeedbackAttempts"] I am just not sure how to refine this path to also limit the results based on the nodes content. Is there any way to do this using XPath?
