simulate

I want to simulate click on GMail COMPOSE button using JS without JQuery. Here is button: <div class="T-I J-J5-Ji T-I-KE L3" role="button" tabindex="0" gh="cm" style="-webkit-user-select: none;">COMPOSE</div> Here is my js: var element = document.getElementsByClassName('T-I-KE')[0]; element.click(); Result: undefined in all browsers Image: http://i.imgur.com/4IX9DZX.png Already tried that: var event = document.createEvent("MouseEvent"); event.initEvent("click",true,true); var element=document.getElementsByClassName("T-I-KE")[0]; element.dispatchEvent(event); Result: true . But nothing happens.

At the beginning of this year, I tried to implement an android-app which could stream ALL system-audio to a remote system. This was not easy because (at that time) there was no way to get all system-audio. So I developed a kernel-module which hijacked the audio. But it was a bit buggy and hard to release. So I stopped work on it. But now, some months later I wonder if it is possible to: Connect via bluetooth to myself (= simulate bluetooth), because then I can forward system-audio to it via API and then fetch it on the other side. Anyone an idea? domsom I doubt it. For a couple of reasons

I want to simulate many key press events. I found a solution by using XTestFakeKeyEvent , but when I simulate more than 210 times my program raises a "Maximum number of clients reached" segmentation fault. I don't known how to solve this problem. My code here: #include <X11/Xlib.h> #include <X11/keysym.h> #include <X11/extensions/XTest.h> #include <stdio.h> #define PRESS_UP 0 #define PRESS_DOWN 1 #define PRESS_LEFT 2 #define PRESS_RIGHT 3 #define PRESS_ENTER 4 #define PRESS_ESC 5 #define PRESS_HOME 6 Display *display; unsigned int keycode; int press(int key){ display = XOpenDisplay(NULL); if

How can you simulate/stress test about 100 users accessing a given shared resource (e.g. Database) in a c# unit test? Assuming you're accessing real DB you're in the scope of integration tests. The simplest way is to access the resource from multiple threads. For example: [Test] public void SimpleStressTest() { bool wasExceptionThrown = false; var threads = new Thread[100]; for(int i = 0; i < 100; i++) { threads[i] = new Thread(new ThreadStart((Action)(() => { try { AccessDB(); } catch(Exception) { wasExceptionThrown = true; } }))); } for(int i = 0; i < 100; i++) { threads[i].Start(); } for
