c++ - How to map 2 char* arrays directly into std::map<std::string,std::string> -


i have 2 char arrays "const char *arr1[arrsize] = {"blah1", "wibble1", "shrug1"};". putting them vector found nice quick solution:

void fillvectest() {     const int arrsize = 3;     const char *arr1[arrsize] = {"blah1", "wibble1", "shrug1"};     const char *arr2[arrsize] = {"blah2", "wibble2", "shrug2"};     std::vector<std::string> vec1(arr1, arr1+arrsize);     std::vector<std::string> vec2(arr2, arr2+arrsize);     std::vector<std::string>::iterator l_it1vec1;     std::vector<std::string>::iterator l_it = vec1.end();     l_it = find(vec1.begin(), vec1.end(), std::string("blah1"));     if(l_it != vec1.end())     {       size_t l_pos = l_it - vec1.begin();       printf("found %s, pos=%u val: %s\n", l_it->c_str(),l_pos, vec2[l_pos].c_str());     }  }

now thought should possible put both directly map arr1 key , arr2 value. tried ways didn't succeed.

void fillmaptest() {     const int arrsize = 3;     const char *arr1[arrsize] = {"blah1", "wibble1", "shrug1"};     const char *arr2[arrsize] = {"blah2", "wibble2", "shrug2"};     std::map<std::string,std::string> map1;//(pair(arr1,arr1), pair(arr1+arrsize,arr2+arrsize));     std::map<std::string,std::string>::iterator l_it1map1;     //l_it1map1 = find(map1.begin(), map1.end(), std::string("blah1"));     if(l_it1map1 != map1.end())     {       printf("found key: %s, val: %s\n",l_it1map1->first.c_str(), l_it1map1->second.c_str());     }  }   int _tmain(int /*argc*/, _tchar* /*argv[]*/) {   fillvectest();   fillmaptest();   return 0; }

i think commented lines in function "fillmaptest" need solved. constuctor , find don't work want.

please has stl expert idea?

the easiest way write this:

std::map<std::string, std::string> m {     { "key1", "value1" },     { "key2", "value2" }, };

this requires compiler support initializer lists (a feature of c++11).

jquery - How can I dynamically add a browser tab? -

since using iframes house external pages are, accounts "not preferred method" , disallowed sites (flickr, one), want dynamically generate browser tabs. e.g., when user submits form, want dynamically generate tab on browser in response submitted. e.g., might want add new tab url like: http://www.bigsurgarrapata.com/contact how in jquery? you want form target attribute action attribute. http://www.w3schools.com/tags/att_form_target.asp browsers have ultimate control on result of target attribute open new tab value of _blank. <form action="contact_submit.php" target="_blank" method="post">

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
