c# - Keep the file open, don't lose data when the app crashes -


i need log info file around 1000-2000 times minute. need save info in case app crashes.

currently here's i'm doing:

using(streamwriter sw=new streamwriter(filename,true)) {     sw.writeline(info); }

this works, it's extremely slow.

i'd doing this:

static streamwriter sw=new streamwriter(file,true);  ....  public static void main(...) {     .....     sw.writeline(....); }

but when write code this, i'm afraid info store lost when app crashes.

what can preserve info in file without having open , close time?

you can call streamwriter.flush() after each write.

public static void main(...) {     .....     sw.writeline(....);     sw.flush(); }

but should use nlog or log4net!

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
