  • MIN array function non zeros only

    - by user1717622
    I have been trying to get this array function to output (non-zero) minimum values in the 'FINAL DATA' AE column. Can you see a structural error in this formula? =IF($C$4="All EMEA", MIN(IF('FINAL DATA'!$2:$AE$250000<>0, ('FINAL DATA'!$J$2:$J$250000=$C$4)*('FINAL DATA'!$E$2:$E$250000=$E$4)*( 'FINAL DATA'!$AE$2:$AE$250000))), MIN(IF('FINAL DATA'!$AE$2:$AE$250000<>0, ('FINAL DATA'!$K$2:$K$250000=$C$4)*('FINAL DATA'!$E$2:$E$250000=$E$4)*( 'FINAL DATA'!$AE$2:$AE$250000))) )

  • No Matching Function Error for inserting into a list in c++

    - by Josh Curren
    I am getting an error when I try to insert an item into a list (in C++). The error is that there is no matching function for call to the insert(). I also tried push_front() but got the same error. Here is the error message: main.cpp:38: error: no matching function for call to ‘std::list<Salesperson, std::allocator<Salesperson> >::insert(Salesperson&)’ /usr/lib/gcc/i686-pc-cygwin/4.3.4/include/c++/bits/list.tcc:99: note: candidates are: std::_List_iterator<_Tp> std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp>, const _Tp&) [with _Tp = Salesperson, _Alloc = std::allocator<Salesperson>] /usr/lib/gcc/i686-pc-cygwin/4.3.4/include/c++/bits/stl_list.h:961: note: void std::list<_Tp, _Alloc>::insert(std::_List_iterator<_Tp>, size_t, const _Tp&) [with _Tp = Salesperson, _Alloc = std::allocator<Salesperson>] Here is the code: #include <stdlib.h> #include <iostream> #include <fstream> #include <string> #include <list> #include "Salesperson.h" #include "Salesperson.cpp" #include "OrderedList.h" #include "OrderedList.cpp" using namespace std; int main(int argc, char** argv) { cout << "\n------------ Asn 8 - Sales Report ------------" << endl; list<Salesperson> s; int id; string fName, lName; int numOfSales; string year; std::ifstream input("Sales.txt"); while( !std::getline(input, year, ',').eof() ) { input >> id; input >> lName; input >> fName; input >> numOfSales; Salesperson sp = Salesperson( id, fName, lName ); s.insert( sp ); //THIS IS LINE 38 ************************** for( int i = 0; i < numOfSales; i++ ) { double sale; input >> sale; sp.sales.insert( sale ); } } cout << endl; return (EXIT_SUCCESS); }

  • run a function when a user clicks on any list element

    - by sova
    This is probably a very common question, but I was unable to find an answer myself; All my list elements call the function setQuery like this onClick="admin_stats.setQuery(this);" rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked? I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here? Before I reinvent a rather square-looking wheel I thought I might ask =)

  • Merge Function In Entity FrameWork?

    - by Ahmed
    In NHibernate there is a merge function that does the following: if there is a persistent instance with the same identifier currently associated with the session, copy the state of the given object onto the persistent instance if there is no persistent instance currently associated with the session, try to load it from the database, or create a new persistent instance the persistent instance is returned Is this possible in EF? I mean this part : copy the state of the given object onto the persistent instance. And if i used ApplyCurrentValues it seemes to be as update behavior or not?

  • Trigger function on deserialization

    - by Tom Savage
    I have a class with a number of fields which are normally calculated in the constructor from other data in the class. They are not serialized to XML because any changes to the rest of the data will likely require their recalculation. Is there a way I can set up a function call to be triggered on deserialization?

  • How to implement Chord function using GDIplus?

    - by leo4ever
    Here are the GDI functions Chord() provided by MFC: BOOL Chord( int x1, int y1, int x2, int y2, int x3, int y3, int x4, int y4 ); BOOL Chord( LPCRECT lpRect, POINT ptStart, POINT ptEnd ); It seems to me that no such method is privided by GDI+ (the Graphics class), so how do I implement my own Chord function (with the exact same prototype) ? By the way, I just don't understand why does MS just don't provide them. Thanks.

  • static thread function access non-static class member in C++

    - by user397390
    Class Test{ int value; static void* thread_func(void* args){ value++; } void newthread(){ pthread_create(&thread_func,...); } } I'm trying to create a thread in Class Test. Therefore compiler forces me to make thread_func static. However I cannot access the non-static member "value" anymore. It says: invalid use of member 'Class::value' in static member function Is there a way around it?

  • Is return an operator or a function?

    - by eSKay
    This is too basic I think, but how do both of these work? return true; // 1 and return (true); // 2 Similar: sizeof, exit My guess: If return was a function, 1 would be erroneous. So, return should be a unary operator that can also take in brackets... pretty much like unary minus: -5 and -(5), both are okay. Is that what it is - a unary operator?
