c++ - Exception Handling : But do not end up in the catch block -


i'm getting unhandled exception in function. function called many times. 

try {   unsigned char* b1 = new unsigned char[length];  //<---here   unsigned char* b2 = new unsigned char[length];   //do stuff doesn't seem throw exception...then @ end   delete[] b1;   delete[] b2; } catch (...) {     cout<< "error..." <<end;  }

thing is, unhandled exception occurs @ random times. breaks on first statement. , other issue is: why isn't caught? visual studio halts , i'm in new.cpp.

and third question/issue is: how can track down problem? length never uninitialized amount; around 512.

seems cout << ... requires memory allocation, cannot it. configure debugger break execution when exception thrown (as other people suggest) , see thrown , @ point. btw, sutter writes shouldn't try catch memory allocation exceptions @ - it's quite hard needed error reporting without memory allocations, , these fail, why bother. (and maybe not these exceptions @ - virtual memory & swapping such wonderful things...)

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
