I'm creating a C# application, could be WinForm, but preferably console application, which needs to capture keyboard shortcuts even when the application is not in the foreground. How would one do this, I know this is possible as i.e. Songbird can do this. This keyboard shortcuts would be of the form ctrl + -> I so far don't have any code as I don't even have the slightest idea on how to register keyboard shortcuts globally. You should use RegisterHotkey and not a keyboard hook. Using a global keyboard hook when you just want a global hotkey is an abuse of the api. It also has negative

I can imagine 3 type of visibility for variables (but I think there are more): Variable is used within a method and any changes of the value of this variable are not visible from outside of the method (so it is local for a particular method). A variable is local to the class meaning that it is unvisible from outisde of the class. However, any method of the class can easily see and change value of this variable without necessity to give the variable in the list of arguments of methods (so it is kind of global within the class). Variable can be accessed by "objectName.variableName". How do I

I have made the Graph class, and i want to simulate a distribution network. The Graph works 100%. But, i want to use that same struct/class in all my application! For example: I have Form1 that shows the simulation, but i want to insert Nodes (for example) but i want to do it in Form2! Since the data is always in the same class, i could make my Graph instance global but C# does not take global variables. So, how would i solve this? Any ideas? Thank you! Give the forms a reference to the Graph in their constructor. Graph g = new Graph(); Form1 f1 = new Form1(g); Form2 f2 = new Form2(g); Then

I hate using global variables, and everyone should. If a language has no way around using global variables it should be updated. Currently, I don't know any good alternative to using global variables in Matlab, when efficiency is the goal. Sharing data between callbacks can be done in only 4 ways that I am aware of: nested functions getappdata (what guidata uses) handle-derived class objects global variables nested functions forces the entire project to be in a single m-file, and handle-derived class objects (sent to callbacks), gives unreasonable overhead last I checked. Comparing getappdata

Just started playing with Android and I'm trying to create an app that has free and paid version. I'm new to Java as well but I've managed to create a simple working application in Eclipse which consists of 2 main projects (one for the free version, and one for the paid version). I also have a library project which contains shared code (activities, resources, strings etc) and is referenced by the main projects. What I want to do (and this may well be the wrong approach) is enable or disable things in the the library code depending on whether I'm running the free or paid version. So for example

This is a simple question. I know global variables are created when they are declared outside a function (says w3schools.com). My question is, if I create a global variable and edit it in a function, does it become local? Does the new value given by the function become the global value? In general, no, editing a global does not make it local: var myglob = 5; function incGlob() { myglob = myglob + 1; } incGlob(); console.log(myglob); // is 6 now However, if you pass the global variable as an argument, the argument is a local copy: var myglob = 5; function incArg(myloc) { myloc = myloc + 1; }

I am making a quiz game. However, I need to add a score variable that can be modified. The way the game works is it uses a few different activities. How can I transmit this score and modify it throughout the activities. Ryan Reeves Here's an example of passing an integer from one activity to another activity. Start ActivityA and pass it the int like this: Intent theIntent = new Intent(this, ActivityA.class); theIntent.putExtra("somename", intVariable); startActivity(theIntent); Get the integer from within ActivityA like this: int i = getIntent().getIntExtra("somename"); trying this do not work

Is there anything wrong with connecting and closing to a database by calling the function below with the mysql_query and mysql_fetch_array commands between the two <?php function dbconnect() { $sql = "localhost"; $username = "------"; $password = "-----"; $connection = mysql_connect($sql, $username, $password) or die("unwable to cct"); $databse = mysql_select_db("-------", $connection); global $connection; } function close() { global $connection; mysql_close($connection); } dbconnect(); $query = "Some SQL Statement"; $data = mysql_query($query, $connection); - L1 while (mysql_fetch_assoc($data

When I try to execute the code below, the first_list gets modified while no changes occur to the second one. Is there a way to replace an outside list with a brand new list, or calling list methods is the only thing I'm allowed to do from inside class methods? I tried adding global keyword before the assignment operation, but it produces a syntax error. first_list = [] second_list = [] class MyClass: def change_values(self): first_list.append('cat') second_list = ['cat'] test = MyClass() test.change_values() print(first_list) print(second_list) First: It's almost NEVER a good idea to have

Ok, maybe my brain is just shut off, but I can't get this to work. Here's the complete code: Page1.php: <?php $something = "hello"; include "Page2.php"; ?> Page2.php: <?php echo $something; ?> Desired output (when navigating to Page1.php): hello The real output is blank. I have tried putting the global keyword everywhere, and nothing happens. Am I missing something? I cannot replicate this error, just tried this on my localhost and copied and pasted your code from here. I suspect you have some sort of syntax error. Turn on error reports and see if you get any errors. Doc I know this is a late
