I'm making a simple WinForm car race game. I've got two objects - cars, and they move on the form when key is pressed (Form1KeyDown_Event). The only thing is, that when one player press a key, the other player cannot press his key (nothing happens). But when the first player releases the key, second player can press one his keys and normally control his car. How can I listen for two player keys simultaneously? Should I use threads and have each car on its own thread? Here's a simple example of what you can do in order to listen to several keys at the same time, using the keyup and keydown

I have a dataframe as below. Based on few conditions, I need to retrive the column. Wifi_User1 Wifi_User2 Wifi_User3 Thermostat Act_User1 Act_User2 Act_User3 -58 -48 -60 18 0 1 0 -60 -56 -75 18 0 1 1 -45 -60 -45 18 0 1 1 -67 -45 -60 18 1 0 1 -40 -65 -65 18 1 0 1 -55 -78 -74 18 1 0 0 -55 -45 -65 18 1 0 0 -67 -45 -44 18 0 0 0 -65 -68 -70 18 0 0 0 -70 -70 -65 24 0 0 0 -72 -56 -45 24 0 1 0 -75 -45 -60 24 0 1 0 -77 -48 -65 24 0 0 0 The conditions are as follows: if (Wifi_User1==Wifi_User2) or (Wifi_User2==Wifi_User3) or (Wifi_User3==Wifi_User1) or (Wifi_User1==Wifi_User2==Wifi_User3) and when the

My goal is to use the d3 force layout to display two different networks that share the same nodes. For example, among four people, you could define a social network and a genealogy network; the nodes would be the same (people) but the links (relationships) could be different. Despite creating two separate force layouts, two separate svg canvases, and trying to define separate variables, the nodes are sharing x and y positional information. Here is a minimal example, in which dragging nodes on one network changes their positions in the other network: http://amath.colorado.edu/student/larremore

i want to open multiple dialog boxes by using the same class on both the button and the content div. The below works but only for the first time. jQuery('.helpDialog').hide(); jQuery('.helpButton').click(function() { jQuery(this).next('.helpDialog').dialog({ autoOpen: true, title: 'Help', width: 500, height: 300, position: [180,10], draggable: true, resizable: false, modal: false }); return false; }); we know the reason for this http://blog.nemikor.com/2009/04/08/basic-usage-of-the-jquery-ui-dialog/ "the second call is ignored because the dialog has already been instantiated on that element."

I'm working on a web app using PHP on Apache. $_SESSION variables are used quite a bit for the information that must persist across pages. We need each user to be able to open multiple concurrent sessions, either as new tabs or new windows, depending on their choice of browser. Right now when a user opens an addition tab or window and goes to the site the existing session is adopted. How can I prevent this so that the user must (or may) log in and start a new session, without it interfering with any existing session(s) they already have open? Our temporary workaround is to use multiple
