CTRL+P (or File > Print) == Use print.css Hit button called "Basic Print" == Use basic-print.css 回答1: This is just an idea, but have you tried loading the basic-print.css file with

问题 I'm trying to find the mapped network printers of the signed in user. I found this script here: GetMappedNetworkPrinters, but it is from a few years ago and there isn't a comment section so I'm not sure where to ask questions about the issues... When I run this script I run into WMI errors on some machines, but the confusing part is for the computers that it does bring information back for I get the notice that there are no mapped printers... Any idea how to adjust the script so that it might

问题 Is it possible or not?If yes,it will be a big help for debugging. Update: For metadata,I mean the content of after given|when|then statement,such as: def "test case"... given:"some preconditions" when:"do something" then:"some result" ... I want that blow content got printed: "test case" begins "some preconditions" "do something" "some result" 回答1: Currently this is not possible because even if you write a Spock extension, the deepest you can hook into at the moment is feature method

问题 In my web page, I'm using 2 stylesheets : <link rel="stylesheet" href="css/screen-layout.css" media="screen" type="text/css" /> <link rel="stylesheet" href="css/print-layout.css" media="print" type="text/css" /> inside print-layout.css there is : .ui-dialog * {display: none !important;} When I viewed my webpage on IE7, it's supposed to ignore the media="print" one, but it didn't, it applied the display: none , causing all the elements to be hidden. And in the debugbar plugin for IE7, I can

问题 This is my code to print some data: System.Drawing.Font valueFont = new System.Drawing.Font("Arial", 15, System.Drawing.FontStyle.Regular); string dataToPrint = ""; dataToPrint += fixLength("رقم بطاقة التسويق") + farmID.Text + Environment.NewLine; dataToPrint += fixLength("إسم صاحب المزرعة") + farmOwner.Text + Environment.NewLine; dataToPrint += fixLength("رقم المزرعة") + farmNumber.Text + Environment.NewLine; dataToPrint += fixLength("الموبايل") + farmMobile.Text + Environment.NewLine;

问题 I read somewhere that regardless of the resolution of the printer, the page will print exactly the same when printing a fixeddocument. Say you had a document that printed on one page on printer x, and suppose printer y has a higher resolution than printer x... when you print the document on printer y, would it auto size to fill the whole page? or would it not fill? thanks EDIT** I read about fixed documents here: http://msdn.microsoft.com/en-us/library/ms748388.aspx more specifically, this

问题 So I have a 2d array I'm using as a gridmap where each array block is a space on a map. So in my main() I've initialized array 'Map' with char Map[ROWS][COLS]={'x'}; ROWS = 10 and COLS = 20 Later I call function PrintMap with void PrintMap(const char Map[ROWS][COLS], const bool showTreasure) { for (int countr=0; countr<ROWS;countr++){ for (int countc=0; countc<COLS;countc++){ //print map if (!showTreasure){ if (Map[countr][countc]!='T') cout << Map[countr][countc]; else cout << '*'; } else {
