  • Passing an array argument from Excel VBA to a WCF service

    - by PrgTrdr
    I'm trying to pass an array as an argument to my WCF service. To test this using Damian's sample code, I modified GetData it to try to pass an array of ints instead of a single int as an argument: using System; using System.ServiceModel; namespace WcfService1 { [ServiceContract] public interface IService1 { [OperationContract] string GetData(int[] value); [OperationContract] object[] GetSomeObjects(); } } using System; namespace WcfService1 { public class Service1 : IService1 { public string GetData(int[] value) { return string.Format("You entered: {0}", value[0]); } public object[] GetSomeObjects() { return new object[] { "String", 123, 44.55, DateTime.Now }; } } } Excel VBA code: Dim addr As String addr = "service:mexAddress=""net.tcp://localhost:7891/Test/WcfService1/Service1/Mex""," addr = addr + "address=""net.tcp://localhost:7891/Test/WcfService1/Service1/""," addr = addr + "contract=""IService1"", contractNamespace=""http://tempuri.org/""," addr = addr + "binding=""NetTcpBinding_IService1"", bindingNamespace=""http://tempuri.org/""" Dim service1 As Object Set service1 = GetObject(addr) Dim Sectors( 0 to 2 ) as Integer Sectors(0) = 10 MsgBox service1.GetData(Sectors) This code works fine with the WCF Test Client, but when I try to use it from Excel, I have this problem. When Excel gets to the service1.GetData call, it reports the following error: Run-time error '-2147467261 (80004003)' Automation error Invalid Pointer It looks like there is some incompatibility between the interface specification and the VBA call. Have you ever tried to pass an array from VBA into WCF? Am I doing something wrong or is this not supported using the Service moniker?

  • Expression Tree with Property Inheritance causes an argument exception

    - by Adam Driscoll
    Following this post: link text I'm trying to create an expression tree that references the property of a property. My code looks like this: public interface IFoo { void X {get;set;} } public interface IBar : IFoo { void Y {get;set;} } public interface IFooBarContainer { IBar Bar {get;set;} } public class Filterer { //Where T = "IFooBarContainer" public IQueryable<T> Filter<T>(IEnumerable<T> collection) { var argument = Expression.Parameter(typeof (T), "item"); //... //where propertyName = "IBar.X"; PropertyOfProperty(argument, propertyName); } private static MemberExpression PropertyOfProperty(Expression expr, string propertyName) { return propertyName.Split('.').Aggregate<string, MemberExpression>(null, (current, property) => Expression.Property(current ?? expr, property)); } } I receive the exception: System.ArgumentException: Instance property 'X' is not defined for type 'IBar' ReSharper turned the code in the link above into the condensed statement in my example. Both forms of the method returned the same error. If I reference IBar.Y the method does not fail.

  • What's the boost way to create a functor that binds out an argument

    - by Mordachai
    I have need for a function pointer that takes two arguments and returns a string. I would like to pass an adapter that wraps a function that takes one argument, and returns the string (i.e. discard one of the arguments). I can trivially build my own adapter, that takes the 2 arguments, calls the wrapped function passing just the one argument through. But I'd much rather have a simple way to create an adapter on the fly, if there is an easy way to do so in C++/boost? Here's some details to make this a bit more concrete: typedef boost::function<CString (int,int)> TooltipTextFn; class MyCtrl { public: MyCtrl(TooltipTextFn callback = boost::bind(&MyCtrl::GetCellText, this, _1, _2)) : m_callback(callback) { } // QUESTION: how to trivially wrapper GetRowText to conform to TooltipTextFn by just discarding _2 ?! void UseRowText() { m_callback = boost::bind(&MyCtrl::GetRowText, this, _1, ??); } private: CString GetCellText(int row, int column); CString GetRowText(int row); TooltipTextFn m_callback; } Obviously, I can supply a member that adapts GetRowText to take two arguments and only passes the first to GetRowText() itself. But is there already a boost binder / adapter that lets me do that?

  • With this generics code why am I getting "Argument 1: cannot convert from 'ToplogyLibrary.Relationsh

    Hi, Any see why I'm getting a "Argument 1: cannot convert from 'ToplogyLibrary.RelationshipBase' to 'TRelationship'" in the code below, in CreateRelationship() ? public class TopologyBase<TKey, TNode, TRelationship> where TNode : NodeBase<TKey>, new() where TRelationship : RelationshipBase<TKey>, new() { // Properties public Dictionary<TKey, TNode> Nodes { get; private set; } public List<TRelationship> Relationships { get; private set; } // Constructors protected TopologyBase() { Nodes = new Dictionary<TKey, TNode>(); Relationships = new List<TRelationship>(); } // Methods public TNode CreateNode(TKey key) { var node = new TNode {Key = key}; Nodes.Add(node.Key, node); return node; } public void CreateRelationship(TNode parent, TNode child) { // Validation if (!Nodes.ContainsKey(parent.Key) || !Nodes.ContainsKey(child.Key)) { throw new ApplicationException("Can not create relationship as either parent or child was not in the graph: Parent:" + parent.Key + ", Child:" + child.Key); } // Add Relationship var r = new RelationshipBase<TNode>(); r.Parent = parent; r.Child = child; Relationships.Add(r); // *** HERE *** "Argument 1: cannot convert from 'ToplogyLibrary.RelationshipBase<TNode>' to 'TRelationship'" } } public class RelationshipBase<TNode> { public TNode Parent { get; set; } public TNode Child { get; set; } } public class NodeBase<T> { public T Key { get; set; } public NodeBase() { } public NodeBase(T key) { Key = key; } }

  • derived class as default argument g++

    - by Vincent
    Please take a look at this code: template<class T> class A { class base { }; class derived : public A<T>::base { }; public: int f(typename A<T>::base& arg = typename A<T>::derived()) { return 0; } }; int main() { A<int> a; a.f(); return 0; } Compiling generates the following error message in g++: test.cpp: In function 'int main()': test.cpp:25: error: default argument for parameter of type 'A<int>::base&' has type 'A<int>::derived' The basic idea (using derived class as default value for base-reference-type argument) works in visual studio, but not in g++. I have to publish my code to the university server where they compile it with gcc. What can I do? Is there something I am missing?

  • Why do I get "mysql_query(): supplied argument is not a valid"

    - by Brian Ojeda
    Why do I get a "mysql_query(): supplied argument is not a valid" for the first... $r = mysql_query($q, $connection); In the following code... $bId = trim($_POST['bId']); $title = trim($_POST['title']); $story = trim($_POST['story']); $q = "SELECT * "; $q .= "FROM " . DB_NAME . ".`blog` "; $q .= "WHERE `blog`.`id` = {$bId}"; $r = mysql_query($q, $connection); //confirm_query($r); if (mysql_num_rows($r) == 1) { $q = "UPDATE " . DB_NAME . ".`blog` SET `title` = '{$title}', `story` = '{$story}' WHERE `id` = {$bId}"; $r = mysql_query($q, $connection); if (mysql_affected_rows() == 1) { //Successful $data['success'] = true; $date['errors'] = false; $date['message'] = "You are the Greatest!"; } else { //Fail $data['success'] = false; $data['error'] = true; $date['message'] = "You can't do it fool!"; } } I also get an "mysql_num_rows(): supplied argument is not a valid MySQL result resource" error too. Side notes: I am using 1&1 Hosting (worst hosting ever), custom .htaccess file with one line text to enable PHP 5.2 (only why with 1&1 Hosting).

  • Argument type deduction, references and rvalues

    - by uj2
    Consider the situation where a function template needs to forward an argument while keeping it's lvalue-ness in case it's a non-const lvalue, but is itself agnostic to what the argument actually is, as in: template <typename T> void target(T&) { cout << "non-const lvalue"; } template <typename T> void target(const T&) { cout << "const lvalue or rvalue"; } template <typename T> void forward(T& x) { target(x); } When x is an rvalue, instead of T being deduced to a constant type, it gives an error: int x = 0; const int y = 0; forward(x); // T = int forward(y); // T = const int forward(0); // Hopefully, T = const int, but actually an error forward<const int>(0); // Works, T = const int It seems that for forward to handle rvalues (without calling for explicit template arguments) there needs to be an forward(const T&) overload, even though it's body would be an exact duplicate. Is there any way to avoid this duplication?

  • Invalid Argument javascript error only on certain computers

    - by Jen
    Getting an error whenever we click a particular button/link on our site. It is generating a javascript "Invalid Argument" error. I know in the other posts it is typically because it is a syntax error in the javascript however it only just seems to have started happening and it doesn't happen on all pcs. ie. in our client's environment if I remote onto their web server and view the uat website I get the javascript error. If I remote onto their sql server and view the uat website I don't get the javascript error. If it was a syntax error then I would always get the error wouldn't I? both browsers are the same version of IE6 (yeah I know...) :) I have tried deleting temporary internet files - including viewing the files and deleting them myself - but no joy. client uses citrix.. and they're all getting the error :( Any ideas would be appreciated - Thanks! :) Update - Sorry I haven't posted specific code as there is too much to post (and I'm not sure where the error is occurring). The "button" launches a new window which in turn opens up a couple of aspx pages and calls lots of javascript. So the window opens ok, and there's a function that gets called to resize the window - but before it calls the resizing of the window/content it throws the invalid argument error. Am busy trying to get alerts to trigger to see if I can see where it's falling over but so far no luck. Again not sure why this error doesn't occur when I use a particular PC (same browser version)

  • Angular throws "Error: Invalid argument." in IE

    - by przno
    I have a directive which takes element's text and places wbr elements after every 10th character. I'm using it for example on table cells with long text (e.g. URLs), so it does not span over the table. Code of the directive: myApp.directive('myWbr', function ($interpolate) { return { restrict: 'A', link: function (scope, element, attrs) { // get the interpolated text of HTML element var expression = $interpolate(element.text()); // get new text, which has <wbr> element on every 10th position var addWbr = function (inputText) { var newText = ''; for (var i = 0; i < inputText.length; i++) { if ((i !== 0) && (i % 10 === 0)) newText += '<wbr>'; // no end tag newText += inputText[i]; } return newText; }; scope.$watch(function (scope) { // replace element's content with the new one, which contains <wbr>s element.html(addWbr(expression(scope))); }); } }; }); Works fine except in IE (I have tried IE8 and IE9), where it throws an error to the console: Error: Invalid argument. Here is jsFiddle, when clicking on the button you can see the error in console. So obvious question: why is the error there, what is the source of it, and why only in IE? (Bonus question: how can I make IE dev tools to tell me more about error, like the line from source code, because it took me some time to locate it, Error: Invalid argument. does not tell much about the origin.) P.S.: I know IE does not know the wbr at all, but that is not the issue. Edit: in my real application I have re-written the directive to not to look on element's text and modify that, but rather pass the input text via attribute, and works fine now in all browsers. But I'm still curious why the original solution was giving that error in IE, thus starting the bounty.

  • C++ template-function -> passing a template-class as template-argument

    - by SeMa
    Hello, i try to make intensive use of templates to wrap a factory class: The wrapping class (i.e. classA) gets the wrapped class (i.e. classB) via an template-argument to provide 'pluggability'. Additionally i have to provide an inner-class (innerA) that inherits from the wrapped inner-class (innerB). The problem is the following error-message of the g++ "gcc version 4.4.3 (Ubuntu 4.4.3-4ubuntu5)": sebastian@tecuhtli:~/Development/cppExercises/functionTemplate$ g++ -o test test.cpp test.cpp: In static member function ‘static classA<A>::innerA<iB>* classA<A>::createInnerAs(iB&) [with iB = int, A = classB]’: test.cpp:39: instantiated from here test.cpp:32: error: dependent-name ‘classA::innerA<>’ is parsed as a non-type, but instantiation yields a type test.cpp:32: note: say ‘typename classA::innerA<>’ if a type is meant As you can see in the definition of method createInnerBs, i intend to pass a non-type argument. So the use of typename is wrong! The code of test.cpp is below: class classB{ public: template < class iB> class innerB{ iB& ib; innerB(iB& b) :ib(b){} }; template<template <class> class classShell, class iB> static classShell<iB>* createInnerBs(iB& b){ // this function creates instances of innerB and its subclasses, // because B holds a certain allocator return new classShell<iB>(b); } }; template<class A> class classA{ // intention of this class is meant to be a pluggable interface // using templates for compile-time checking public: template <class iB> class innerA: A::template innerB<iB>{ innerA(iB& b) :A::template innerB<iB>(b){} }; template<class iB> static inline innerA<iB>* createInnerAs(iB& b){ return A::createInnerBs<classA<A>::template innerA<> >(b); // line 32: error occurs here } }; typedef classA<classB> usable; int main (int argc, char* argv[]){ int a = 5; usable::innerA<int>* myVar = usable::createInnerAs(a); return 0; } Please help me, i have been faced to this problem for several days. Is it just impossible, what i'm trying to do? Or did i forgot something? Thanks, Sebastian

  • pointer as second argument instead of returning pointer?

    - by Tyler
    I noticed that it is a common idiom in C to accept an un-malloced pointer as a second argument instead of returning a pointer. Example: /*function prototype*/ void create_node(node_t* new_node, void* _val, int _type); /* implementation */ node_t* n; create_node(n, &someint, INT) Instead of /* function prototype */ node_t* create_node(void* _val, int _type) /* implementation */ node_t* n = create_node(&someint, INT) What are the advantages and/or disadvantages of both approaches? Thanks!

  • passing argument 1 from incompatible pointer type

    - by Andrew
    Why does this code...: NSDictionary *testDictionary = [NSDictionary dictionaryWithObjectsAndKeys:kABOtherLabel, @"other", kABWorkLabel, @"work", nil]; throw this warning: warning: passing argument 1 of 'dictionaryWithObjectsAndKeys' from incompatible pointer type Incidentally, the code works as expected, but I don't like leaving warnings un-delt-with. I assume it doesn't like that I'm storing a constant in a dictionary. Well, where can I store it then? Should I just place (void *) before every constant?

  • Coldfusion Components:- The argument passed to the function is not of type numeric

    - by salim.vali
    Hi I have a simple form form.cfm:- <cfset Registr = createObject("component", "forms.Registr") /> <cfset setFoo = createObject('component','forms.Registr).putNUsr(username,password,rating) /> <form name="regFrm" action="#cgi.script_name#" method="post" onsubmit="submitform();" > <tr><td>Username:</td> <td><input type="text" name=" Username" value="#form.

Else i am getting the error as follows:- The RATING argument passed to the putNUsr function is not of type numeric.

  • PHP: variable-length argument list by reference?

    - by GetFree
    Is it possible to create a PHP function that takes a variable number of parameters all of them by reference? It doesn't help me a function that receives by reference an array of values nor a function that takes its arguments wrapped in an object because I'm working on function composition and argument binding. Don't think about call-time pass-by-reference either. That thing shouldn't even exist.
