[ad_1] Your constructor prints one line, so : new This(); System.out.println(new This()); Here you call the constructor twice, and System.out.println() also prints a line, so you get three lines. Also, you are creating two distinct This objects. In your second example, the constructor is only called once, so you get only two lines. This example … Read more
[ad_1] Make sure the call: $(window).on(“resize”, resizePortfolio); is inside the $(document).ready(function() {…}) body, because the scope of the function name is just that function. [ad_2] solved Javascript “— is Not Defined” Error
[ad_1] start_date and stop_date are strings, which don’t support the – operator. If you want to compute their (numerical) difference, define them as integers, i.e. start_date = 20151231171500 stop_date = 20151231174500 or cast them to int: test = int(stop_date) – int(start_date) Caveat: the difference of these numbers would be 3000, not 30. Not sure why … Read more
[ad_1] for group in data { let userNames = group.1.reduce(“username “, combine: { (current, userInfo) -> String in return “\(current), \(userInfo[“username”]!)” }) print(“\(group.0) \(userNames)”) } 2 [ad_2] solved NSDictionary with swift [closed]
[ad_1] valueChanged is a signal of Foo itself, so you should use self.valueChanged.connect(self.do_something) instead of self.t.valueChanged.connect(self.do_something). After all, the value that should be emitted with the signal is determined when the signal is emitted, not when connecting the signal to a slot.

[ad_1] You should read the compiler error messages. The second and third arguments to MessageBox have to have the same type. Either you call MessageBoxA with two char *, or you call MessageBoxW with two wchar_t *. One fix for your code would be to do MessageBoxA(NULL, buff, “User-id”, MB_OK). You are using sprintf_s incorrectly … Read more
[ad_1] You can access a variable as you can access an array, if you were to echo: $string = “test”; echo $string[0]; It would echo t, and onwards. You could concat the string and make a new variable like: $v = “0904201600000123”; $date = $v[0].$v[1].’-‘.$v[2].$v[3].’-‘.$v[4].$v[5].$v[6].$v[7]; echo $date; I tested it on my local machine and … Read more
[ad_1] Numerical derivation and integration in code for physics, mapping, robotics, gaming, dead-reckoning, and controls Pay attention to where I use the words “estimate” vs “measurement” below. The difference is important. Measurements are direct readings from a sensor. Ex: a GPS measures position (meters) directly, and a speedometer measures speed (m/s) directly. Estimates are calculated … Read more
[ad_1] EDIT From SQL Server 2012 and later you might use the FORMAT function if you want to force a date into a formatted text: https://msdn.microsoft.com/en-us/library/hh213505.aspx With earlier versions you might use something like this: DECLARE @d DATETIME=GETDATE(); DECLARE @TargetFormat VARCHAR(100)=’DD/MM/YYYY’; SELECT CONVERT(VARCHAR(100),@d, CASE @TargetFormat WHEN ‘MM/DD/YYYY’ THEN 101 WHEN ‘DD/MM/YYYY’ THEN 103 –add all … Read more

[ad_1] First fix your other issues. Inside separate js file: BrowserName is not defined. Is it supposed to be a var or function? It you want to check the browser you can use navigator.userAgent and test for certain strings. Search this site for more info. Scroll function: be careful with using function names. They may … Read more
[ad_1] You can run Railo on Jetty instead which has more sophisticated URL pattern support I believe (since this is a Tomcat restriction, not a Railo issue per se). 2 [ad_2] solved SES url’s with Railo/tomcat that have dynamic subfolders
[ad_1] Edited: I thought the solution was to make the segue from the view controller instead of from the cell, but as matt said, the segue was correct from the cell but I just had to remove the implementation of didSelectItemAt 2 [ad_2] solved Passing data from CollectionView to DetailVC in Swift 4
[ad_1] Here you go: Z = [[‘A’, ‘B’, ‘C’], [1], [‘x’, ‘y’]] import itertools for element in itertools.product(*Z): print(element) Result: (‘A’, 1, ‘x’) (‘A’, 1, ‘y’) (‘B’, 1, ‘x’) (‘B’, 1, ‘y’) (‘C’, 1, ‘x’) (‘C’, 1, ‘y’) [ad_2] solved Python list ways to select objects [duplicate]
