• WPF: Is there a way to bind to a method using PyBinding?

  - by Jonathan Allen

  Using standard rules, it is a royal pain to data-bind to a method. So I'm wondering if it possible to use PyBinding to do a easy one-way bind.

• Java: omitting a data member from the equals method.

  - by cchampion

  public class GamePiece { public GamePiece(char cLetter, int nPointValue) { m_cLetter=cLetter; m_nPointValue=nPointValue; m_nTurnPlaced=0; //has not been placed on game board yet. } public char GetLetter() {return m_cLetter;} public int GetPointValue() {return m_nPointValue;} public int GetTurnPlaced() {return m_nTurnPlaced;} public void SetTurnPlaced(int nTurnPlaced) { m_nTurnPlaced=nTurnPlaced; } @Override public boolean equals(Object obj) { /*NOTE to keep this shorter I omitted some of the null checking and instanceof stuff. */ GamePiece other = (GamePiece) obj; //not case sensitive, and I don`t think we want it to be here. if(m_cLetter != other.m_cLetter) { return false; } if(m_nPointValue != other.m_nPointValue) { return false; } /* NOTICE! m_nPointValue purposely omitted. It does not affect hashcode or equals */ return true; } @Override public int hashCode() { /* NOTICE! m_nPointValue purposely omitted. It should not affect hashcode or equals */ final int prime = 41; return prime * (prime + m_nPointValue + m_cLetter); } private char m_cLetter; private int m_nPointValue; private int m_nTurnPlaced;//turn which the game piece was placed on the game board. Does not affect equals or has code! } Consider the given piece of code. This object has been immutable until the introduction of the m_nTurnPlaced member (which can be modified by the SetTurnPlaced method, so now GamePiece becomes mutable). GamePiece is used in an ArrayList, I call contains and remove methods which both rely on the equals method to be implemented. My question is this, is it ok or common practice in Java for some members to not affect equals and hashcode? How will this affect its use in my ArrayList? What type of java Collections would it NOT be safe to use this object now that it is mutable? I've been told that you're not supposed to override equals on mutable objects because it causes some collections to behave "strangely" (I read that somewhere in the java documentation).

• Does calling a click method effect the HtmlPage object if there is a 404?

  - by Blankman

  If I call a click method on a HtmlAnchor, and say that page returns a 404, does that mean the HtmlPage will effect, so searching for another link on the page will result in an error because the page's HTML is the error page (assuming the link is NOT on the error page). Can I manually set the page's HTML, and then locate and click on links and continue on from this approach? (other than connecting via a URL)

• How do I avoid web method parameters using proxy classes?

  - by Alex Angas

  I have a serializable POCO called DataUnification.ClientData.ClientInfo in a .NET class library project A. It's used in a parameter for a web service defined in project B: public XmlDocument CreateNewClient(ClientInfo ci, string system) I now wish to call this web method from project C and use the original DataUnification.ClientData.ClientInfo type in the parameter. However due to the generated proxy class it has now become a different type: WebServices.ClientDataUnification.DataUnificationWebService.ClientInfo. As far as .NET is concerned these are not the same types. How can I get around this?

• Why does LINQ-to-Entites recognize my custom method?

  - by BlueRaja The Green Unicorn

  This works: (from o in Entities.WorkOrderSet select o) .Where(MyCustomMethod); This does not: (from o in Entities.WorkOrderSet select new { WorkOrder = o }) .Where(o => MyCustomMethod(o.WorkOrder); I understand why the second doesn't work - but why in the world does the first work!? Shouldn't I get a "custom method not recognized?" For reference, here is MyCustomMethod public bool MyCustomMethod(WorkOrder workOrder) { return !workOrder.WorkOrderNum.StartsWith("A", StringComparison.CurrentCultureIgnoreCase); }

• What is the preferred method of refreshing a combo box when the data changes?

  - by Craig Johnston

  What is the preferred method of refreshing a combo box when the data changes? If a form is open and the combo box data is already loaded, how do you refresh the contents of the combo box without the form having to be closed and reloaded? Do you have to do something on the Click event on the combo box? This would seem to be a potential slow down for the app if there is a hit to the database every time someone clicks on a combo box.
