  • C# - Convert Implict Type to ObservableCollection

    - by user70192
    Hello, I have a LINQ statement that returns an implicit type. I need to get this type to be an ObservableCollection in my Silverlight 3 application. The ObservableCollection constructor in Silverlight 3 only provides an empty constructor. Because of this, I cannot directly convert my results to an ObservableCollection. Here is my code: ObservableCollection<MyTasks> visibleTasks = e.Result; var filteredResults = from visibleTask in visibleTasks select visibleTask; filteredResults = filteredResults.Where(p => p.DueDate == DateTime.Today); visibleTasks = filteredResults.ToList(); // This throws a compile time error How can I go from an implicitly typed variable to an observable collection? Thank you

  • How to pass interface type/GUID reference to an automation method in Delphi

    - by Alan Clark
    In Delphi you can pass class references around to compare the types of objects, and to instantiate them. Can you do the same with interface references being passed to a COM automation server? For example, you can define a method taking a GUID parameter using the type library editor: function ChildNodesOfType(NodeType: TGUID): IMBNode; safecall; In this function I would like to return automation types that support the interface specified by NodeType, e.g. if Supports(SomeNode, NodeType) then result := SomeNode; But the Supports call always fails, I tried passing in the Guids defined in the type library but none of the different types (Ixxx, Class_xxxx, IId_Ixxxx) seem to work.

  • Using XSLT to Find Nodes Given a Set of Parameters

    - by davecardwell
    Sorry about the title—wasn’t sure how to word it. Basically I have some XML like this: <countries> <country handle="bangladesh"/> <country handle="india"/> <country handle="pakistan"/> </countries> And some XSLT like this (which doesn’t work): <xsl:template match="/countries"> <xsl:param name="popular"/> <xsl:apply-templates select="country[count($popular/country[@handle = current()/@handle]) &gt; 0]" /> </xsl:template> <xsl:template match="/countries/country"> … </xsl:template> I want to pass in a list of popular destinations like this: <popular> <country handle="india"/> <country handle="pakistan"/> </popular> …to the /countries template and have it only operate on the ones in the $popular param. At the moment this simply does nothing. Changing the selector to country[true()] operates on them all, so at least I know the basic structure is right. Any ideas? I think I may be getting confused by what is currently “current()”.

  • Using free function as pseudo-constructors to exploit template parameter deduction

    - by Poita_
    Is it a common pattern/idiom to use free functions as pseudo-constructors to avoid having to explicitly specify template parameters? For example, everyone knows about std::make_pair, which uses its parameters to deduce the pair types: template <class A, class B> std::pair<A, B> make_pair(A a, B b) { return std::pair<A, B>(a, b); } // This allows you to call make_pair(1, 2), // instead of having to type pair<int, int>(1, 2) // as you can't get type deduction from the constructor. I find myself using this quite often, so I was just wondering if many other people use it, and if there is a name for this pattern?

  • XSLT - Catching parameters

    - by Brian Roisentul
    The situation is I have two xslt files: one is called from my ASP.NET code, and there, the second xslt file is imported. What I'd like to accomplish is to pass a parameter to the first one so the second xslt(the one that is imported at the first xslt) can read it. My c# code looks like this: var oArgs = new XsltArgumentList(); oArgs.AddParam("fbLikeFeatureName", "", "Facebook_Like_Button"); ltlContentBody.Text = xmlUtil.TransformXML(oXmlDoc, Server.MapPath(eSpaceId + "/styles/ExploringXSLT/ExploreContentObjects.xslt"), true); And I'm catching the param at the first xslt this way: <xsl:param name="fbLikeFeatureName" /> And then, passing it to the second xslt like this(previously, I import that file): <xsl:call-template name="Articles"> <xsl:with-param name="fbLikeFeatureName"></xsl:with-param> </xsl:call-template> Finally, I'm catching the param on the second xslt file as following: <xsl:value-of select="$fbLikeButtonName"/> What Am I doing wrong? I'm kind of new at xslt.

  • Naming Optional Parameters in VSB

    - by SteveNeedsSheetNames
    In Visual Basic, I have Functions with a lot of Optional arguments. I would like to be able to pass just a few of these Optional arguments to a Function without having to use numerous commas and spaces to get to the ones I want. Somewhere I saw a way to name params such as OptVar:=val, but that does not seem to work. Just wondering if there is a way to do this. This would help readability. Thanks in advance for the replies.

  • setting value to the instance of primitive types

    - by Samreen
    I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance. But I can't set the value that I have fetched from database to this instance. public T PerformOperation<T>() { object instance = (T)Activator.CreateInstance(typeof(T)); object result=FetchData(); instance = (T)result; //It gives error on this statement } The function is called as: int result = PerformOperation<int>(); Is there some way of casting the object Type to any generic type which is always primitive?

  • Javascript unable to pass parameters into a property acting as a function

    - by BOverflow
    Currently in a simplified form, my code looks like this function AddFileParam(file_id, name, value) { uploadcontrol.addFileParam(file_id, name, value) } uploadcontrol = new Upload() function upload() { //logic } upload.prototype.AddFileParam = function(file_id, name, value) { //logic }; The code is giving me an error as it states that addFileParam is not a valid function. This is caused by the instance of the function upload (aka. uploadcontrol). This is only occuring in Firefox/Chrome and not in IE. Any ideas on how to fix this?

  • SQL: ATER COLUMN to shorter CHAR(n) type

    - by Rising Star
    I'm working with MS SQL SERVER 2003. I want to change a column in one of my tables to have fewer characters in the entries. This is identical to this question: http://stackoverflow.com/questions/2281336/altering-a-table-column-to-accept-more-characters except for the fact that I want fewer characters instead of more. I have a column in one of my tables that holds nine-digit entries. A developer previously working on the table mistakenly set the column to hold ten-digit entries. I need to change the type from CHAR(10) to CHAR(9). Following the instructions from the discussion linked above, I wrote the statement ALTER TABLE [MY_TABLE] ALTER COLUMN [MY_COLUMN] CHAR(9); This returns the error message "String or binary data would be truncated". I see that my nine-digit strings have a space appended to make them ten digits. How do I tell SQL Server to discard the extra space and convert my column to a CHAR(9) type?

    I have a template class like here (in a header) with a inner class and a static member of type pointer to inner class template <class t> class outer { class inner { int a; }; static inner *m; }; template <class t> outer <t>::inner *outer <t>::m; when i want to define that static member i says "error: expected constructor, destructor, or type conversion before '*' token" on the last line (mingw32-g++ 3.4.5)

  • Does "Value Restriction" mean that there is no higher order functional programming?

    - by Sadache
    Does "Value Restriction" mean that there is no higher order functional programming? I have a problem that each time I try to do a bit of HOP I get caught by a VR error. Example: let simple (s:string)= fun rq->1 let oops= simple "" type 'a SimpleType= F of (int ->'a-> 'a) let get a = F(fun req -> id) let oops2= get "" and I would like to know whether it is a problem of a prticular implementation of VR or it is a general problem that has no solution in a mutable type-infered language that doesn't include mutation in the type system.

  • Initializing objects on the fly

    - by pocoa
    I have a vector called players and a class called Player. And what I'm trying to do is to write: players.push_back(Player(name, Weapon(bullets))); So I want to be able to create players in a loop. But I see an error message says "no matching function for call Player::Player..." Then I've changed that to: Weapon w(bullets); Player p(name, w); players.push_back(p); Here is my Player definition: class Player { public: Player(string &name, Weapon &weapon); private string name; Weapon weapon; } I'm just trying to learn what is the difference between these definitions. And is this the right way to pass an object to an object constructor. Note: These are not my actual class definitions. I'm just trying to learn something about object oriented programming in C++ with coding it. I mean I know that Weapon should be initialized in Player :)
