  • 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))) )

  • C++: Pass array created in the function call line

    - by Jarx
    How can I achieve a result like somebody would expect it according to the following code example: // assuming: void myFunction( int* arr ); myFunction( [ 123, 456, 789 ] ); // as syntactical sugar for... int values[] = { 123, 456, 789 }; myFunction( values ); The syntax I thought would work spit out a compile error. How can I define an argument array directly in the line where the function is called?

  • 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.

  • 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?

  • C++ auto function return type implementation

    - by aaa
    hello. Is there macro, something like BOOST_AUTO, which would allow to emulate automatic return type deduction of function in C++? I mean something like trailing-return-type, http://en.wikipedia.org/wiki/C%2B%2B0x#Alternative_function_syntax thank you

  • 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); }

  • virtaul function

    class a { virtual void foo(void) ; }; class b : public a { public: virtual void foo(void) { cout<< "class b"; } }; int main ( ) { class a *b_ptr = new b ; b_ptr-foo(); } please guide me why the b_ptr-foo() will not call the foo() function of the class b?
