• IE7 z-index problem with Flash content

  - by lbolognini

  I have a problem with flash content in IE7 being always over the menu items I have a structure like the following: <div id='skyscraper_flash'> <!--this id skyscraper_flash is position absolute--> <object> <!--this is wmode transparent--> </object> </div> <div id='menu'> <!--this id menu is also position absolute--> <ul> <li>foo</li> <li>bar</li> </ul> </div> Now then the last item of the menu opens it shows behind the flash content. The skyscraper is on the right of the page content. What should i look into?

• Programmatically Detecting Valid Style Properties In Flex

  - by Joshua

  If I want to know if an object has a particular property I can code this: if (SomeObject.hasOwnProperty('xyz')) { // some code } But some styles masquerade as properties at design time such as Button.color... How can I know what style properties are valid at runtime? ie: What is the equivalent of hasOwnProperty for getStyle/setStyle? In other words how can I know if an object HAS A particular style variable... When I write: MyButton.setStyle('qsfgaeWT','-33'); It won't accomplish anything, but it also doesn't error. How can I know programmatically that 'qsfgaeWT' is NOT a valid style of 'Button'??

• Implementing sub fields in a PropertyGrid

  - by evolve

  Alright so my terminology when it comes to C# isn't great, so I'll attempt to explain this with a small example. If you create a class which you are using within a PropertyGrid and you have the following values: class Test { public Point example { get; set; } } This will produce a PropertyGrid which has an expandable object "example" which has fields X and Y in order to create a "Point". I'm attempting to create an object "name" which has fields "firstname" and "lastname", so I have: class Test { public Name example { get; set; } } public struct Name { public string firstname { get; set; } public string lastname { get; set; } } This however isn't working as intended. I think I need to override some method(s) in order to get this working, however since I don't really have the terminology down for PropertyGrids it is difficult for me to find a solution. Any help would be great.

• Java: JPA classes, refactoring from Date to DateTime

  - by bguiz

  With a table created using this SQL Create Table X ( ID varchar(4) Not Null, XDATE date ); and an entity class defined like so @Entity @Table(name = "X") public class X implements Serializable { @Id @Basic(optional = false) @Column(name = "ID", nullable = false, length = 4) private String id; @Column(name = "XDATE") @Temporal(TemporalType.DATE) private Date xDate; //java.util.Date ... } With the above, I can use JPA to achieve object relational mapping. However, the xDate attribute can only store dates, e.g. dd/MM/yyyy. How do I refactor the above to store a full date object using just one field, i.e. dd/MM/yyyy HH24:mm?

• NHibernate parent-childs save redundant sql update executed

  - by Broken Pipe

  I'm trying to save (insert) parent object with a collection of child objects, all objects are new. I prefer to manually specify what to save\update and when so I do not use any cascade saves in mappings and flush sessions by myself. So basically I save this object graph like: session.Save(Parent) foreach (var child in Parent.Childs) { session.Save(child); } session.Flush() I expect this code to insert Parent row, then each child row, however NHibernate executes this SQL: INSERT INTO PARENT.... INSERT INTO CHILD .... UPDATE CHILD SET ParentId=@1 WHERE Id=@2 This update statement is absolutely unnecessary, ParentId was already set correctly in INSERT. How do I get rid of it? Performance is very important for me.

• Is there a way in CXF to disable the SoapCompressed header for debugging purposes?

  - by Don Branson

  I'm watching CXF service traffic using DonsProxy, and the CXF client sends an HTTP header "SoapCompressed": HttpHeadSubscriber starting... Sender is CLIENT at 127.0.0.1:2680 Packet ID:0-1 POST /yada/yada HTTP/1.1 Content-Type: text/xml; charset=UTF-8 SoapCompressed: true Accept-Encoding: gzip,gzip;q=1.0, identity; q=0.5, *;q=0 SOAPAction: "" Accept: */* User-Agent: Apache CXF 2.2 Cache-Control: no-cache Pragma: no-cache Host: localhost:9090 Connection: keep-alive Transfer-Encoding: chunked I'd like to turn SoapCompressed off in my dev environment so that I can see the SOAP on the wire. I've searched Google and grepped the CXF source code, but don't see anything in the docs or code that reference this. Any idea how to make the client send "SoapCompressed: off" instead, without routing it through Apache HTTPD or the like? Is there a way to configure it at the CXF client, in other words?

• Question regarding common class

  - by Rocky Singh

  I have following two classes: public class A : System.Web.UI.WebControls.Button { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } and public class B : System.Web.UI.WebControls.TextBox { public virtual string X { get { object obj = ViewState["X"]; if (obj != null) return (string)obj; return null; } set { ViewState["X"] = value; } } protected override void OnLoad(EventArgs e) { X=2; } } As you must be seeing the class A and B have exactly the same code , my question is how can I make a common class for it and use these two classes.

• How do I retrieve readonly values when using a DetailsView control to update a record?

  - by lincolnk

  I'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection. I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?

• Why can't I *override* and *new* a Property (C#) at the same time?

  According to this question it seems like you can do this for Methods. What I want to know is why it doesn't work when I try it with properties. public class Foo { public virtual object Value { get; set; } } public class Foo<T> : Foo { public override object Value { get { return base.Value; } set { base.Value = (T)value; //inject type-checking on sets } } public new T Value { get { return (T)base.Value; } set { base.Value = value; } } } Error message from C# 4.0 RC1 Error 1 The type 'ClassLibrary1.Foo' already contains a definition for 'Value' ClassLibrary1\Class1.cs 31 22 ClassLibrary1

• iPhone check for a constant at runtime in universal app

  - by joshue

  I'm making a universal iPad/iPhone app which can use the iPad's VGA out connector to mirror the content of the app on an external screen. However, the iPhone does not have this functionality. given the following code, [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidConnectNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(screenInfoNotificationReceieved:) name:UIScreenDidDisconnectNotification object:nil]; I get this error on the phone at launch (works fine in ipad) "dyld: Symbol not found: _UIScreenDidConnectNotification" presumably because UIScreenDidConnectNotification doesnt' exist yet in 3.13. How do I check for this at runtime?

• Where is a good Address Parser

  - by Brig Lamoreaux

  I'm looking for a good tool that can take a full mailing address, formatted for display or use with a mailing label, and convert it into a structured object. So for instance: // Start with a formatted address in a single string string f = "18698 E. Main Street\r\nBig Town, AZ, 86011"; // Parse into address Address addr = new Address(f); addr.Street; // 18698 E. Main Street addr.Locality; // Big Town addr.Region; // AZ addr.PostalCode; // 86011 Now I could do this using RegEx. But the tricky part is keeping it general enough to handle any address in the world! I'm sure there has to be something out there that can do it. If anyone noticed, this is actually the format of the opensocial.address object.

• How to Override a private set property

  - by David

  Hi, Im using the Microsoft.Office.Interop.MSProject.Resource assembly which has a "UniqueID" property, it has a get but not set. How can I actually set a value? An example would be very much appreciated. --Update-- Ok I can get the value for a property "Name" and set, but Im intersted in the "UniqueId" property that does not have a public set (get only): int ii = (int)resource.GetType().InvokeMember("UniqueID", BindingFlags.GetProperty, null, resource, new object[] { }); resource.GetType().InvokeMember("UniqueID", BindingFlags.SetProperty, null, resource, new object[] {iUid,}); I get the following error {"Number of parameters specified does not match the expected number."} anyway for me to work out how many paramters it needs?

• Design issue with ATG CommercePipelineManager

  - by user1339772

  The definition of runProcess() method in PipelineManager is public PipelineResult runProcess(String pChainId, Object pParam) throws RunProcessException This gives me an impression that ANY object can be passed as the second param. However, ATG OOTB has PipelineManager component referring to CommercePipelineManager class which overrides the runProcess() method and downcast pParam to map and adds siteId to it. Basically, this enforces the client code to send only Map. Thus, if one needs to create a new pipeline chain, has to use map as data structure to pass on the data. Offcourse, one can always get around this by creating a new PipelineManager component, but I was just wondering the thought behind explicitly using map in CommercePipelineManager

• what is wrong: "value Parsers is not a member of package scala.util.parsing.combinator"?

  - by Nick Fortescue

  I've got the above odd error message that I don't understand "value Parsers is not a member of package scala.util.parsing.combinator". I'm trying to learn Parser combinators by writing a C parser step by step. I started at token, so I have the classes: import util.parsing.combinator.JavaTokenParsers object CeeParser extends JavaTokenParsers { def token: Parser[CeeExpr] = ident } abstract class CeeExpr case class Token(name: String) extends CeeExpr This is as simple as I could make it. The code below works fine, but if I uncomment the commented line I get the error message given above: object Play { def main(args: Array[String]) { //val parser: _root_.scala.util.parsing.combinator.Parsers.Parser[CeeExpr] CeeParser.token val x = CeeParser.token print(x) } } In case it is a problem with my setup, I'm using scala 2.7.6 via the scala-plugin for intellij. Can anyone shed any light on this? The message is wrong, Parsers is a member of scala.util.parsing.combinator.

• How to avoid Eclipse warnings when using legacy code without generics?

  - by Paul Crowley

  I'm using JSON.simple to generate JSON output from Java. But every time I call jsonobj.put("this", "that"), I see a warning in Eclipse: Type safety: The method put(Object, Object) belongs to the raw type HashMap. References to generic type HashMap should be parameterized The clean fix would be if JSONObject were genericized, but since it isn't, I can't add any generic type parameters to fix this. I'd like to switch off as few warnings as possible, so adding "@SuppressWarnings("unchecked")" to lots of methods is unappealing, but do I have any other option besides putting up with the warnings?

• Display another field in the referenced table for multiple columns with performance issues in mind

  - by israkir

  I have a table of edge like this: ------------------------------- | id | arg1 | relation | arg2 | ------------------------------- | 1 | 1 | 3 | 4 | ------------------------------- | 2 | 2 | 6 | 5 | ------------------------------- where arg1, relation and arg2 reference to the ids of objects in another object table: -------------------- | id | object_name | -------------------- | 1 | book | -------------------- | 2 | pen | -------------------- | 3 | on | -------------------- | 4 | table | -------------------- | 5 | bag | -------------------- | 6 | in | -------------------- What I want to do is that, considering performance issues (a very big table more than 50 million of entries) display the object_name for each edge entry rather than id such as: --------------------------- | arg1 | relation | arg2 | --------------------------- | book | on | table | --------------------------- | pen | in | bag | --------------------------- What is the best select query to do this? Also, I am open to suggestions for optimizing the query - adding more index on the tables etc... EDIT: Based on the comments below: 1) @Craig Ringer: PostgreSQL version: 8.4.13 and only index is id for both tables. 2) @andrefsp: edge is almost x2 times bigger than object.

• C# - Dictionary with generic array as value

  - by alhazen

  In my class, I want to use a dictionary with the following declaration: Dictionary<string, T[]> Since the operations of my class are exactly the same for all generic types, I do not wish to define my class as generic (which means I would have to create a separate instance of my class for each generic type I insert into the dictionary ?). One alternative I'm attempting is to use Dictionary<string, object> instead: public void Add<T>(string str, T value) { // Assuming key already exists var array = (T[]) dictionary[str]; array[0] = value; } However, when iterating over the dictionary, how do I cast the object value back to an array ? foreach(string strKey in dictionary.Keys) { var array = (T[]) dictionary[strKey]; // How to cast here ? //... array[0] = default(T); } Thanks.

This is the code of a test funcion... it changes the status bar text (OK), prints the page html (OK), changes the html by adding a text and prints again the page html (ok, in the second popup my added text is in the html) But the Internet Explorer window doesnt't show it.

• Help With LINQ: Mixed Joins and Specifying Default Values

  - by Corey O.

  I am trying to figure out how to do a mixed-join in LINQ with specific access to 2 LINQ objects. Here is an example of how the actual TSQL query might look: SELECT * FROM [User] AS [a] INNER JOIN [GroupUser] AS [b] ON [a].[UserID] = [b].[UserID] INNER JOIN [Group] AS [c] ON [b].[GroupID] = [c].[GroupID] LEFT JOIN [GroupEntries] AS [d] ON [a].[GroupID] = [d].[GroupID] WHERE [a].[UserID] = @UserID At the end, basically what I would like is an enumerable object full of GroupEntry objects. What am interested is the last two tables/objects in this query. I will be displaying Groups as a group header, and all of the Entries underneath their group heading. If there are no entries for a group, I still want to see that group as a header without any entries. Here's what I have so far: So from that I'd like to make a function: public void DisplayEntriesByUser(int user_id) { MyDataContext db = new MyDataContext(); IEnumberable<GroupEntries> entries = ( from user in db.Users where user.UserID == user_id join group_user in db.GroupUsers on user.UserID = group_user.UserID into a from join1 in a join group in db.Groups on join1.GroupID equals group.GroupID into b from join2 in b join entry in db.Entries.DefaultIfEmpty() on join2.GroupID equals entry.GroupID select entry ); Group last_group_id = 0; foreach(GroupEntry entry in entries) { if (last_group_id == 0 || entry.GroupID != last_group_id) { last_group_id = entry.GroupID; System.Console.WriteLine("---{0}---", entry.Group.GroupName.ToString().ToUpper()); } if (entry.EntryID) { System.Console.WriteLine(" {0}: {1}", entry.Title, entry.Text); } } } The example above does not work quite as expected. There are 2 problems that I have not been able to solve: I still seem to be getting an INNER JOIN instead of a LEFT JOIN on the last join. I am not getting any empty results, so groups without entries do not appear. I need to figure out a way so that I can fill in the default values for blank sets of entries. That is, if there is a group without an entry, I would like to have a mostly blank entry returned, except that I'd want the EntryID to be null or 0, the GroupID to be that of of the empty group that it represents, and I'd need a handle on the entry.Group object (i.e. it's parent, empty Group object). Any help on this would be greatly appreciated. Note: Table names and real-world representation were derived purely for this example, but their relations simplify what I'm trying to do.
