modifier

问题 Anybody knows how to change this function with preg_replace and the e/ modifier The e/ modifier will be depreciated. function charset_decode_utf_8 ($string) { /* Only do the slow convert if there are 8-bit characters */ /* avoid using 0xA0 (\240) in ereg ranges. RH73 does not like that */ if (! preg_match("/[\200-\237]/", $string) and ! preg_match("/[\241-\377]/", $string)) return $string; // decode three byte unicode characters $string = preg_replace("/([\340-\357])([\200-\277])([\200-\277])

问题 I have a text file which contains things like: "C:\Folder A\Test.txt" I need to copy certain files and their respective containers to a new directory from a directory, but only those files I specify and their parent folder structures. In my batch: for /f "delims=" %%a in (C:\audit\test.txt) do ( robocopy "%%~dpa" "Z:\" "%%~nxa" /E /COPY:DAT /PURGE /MIR /R:1000000 /W:30 ) pause However, it fails the robocopy, probably to do with the trailing backslash. The Source gets mixed up and shows both

问题 This question already has answers here : Warning: preg_replace(): Unknown modifier ']' (3 answers) Closed 5 months ago . I have this HTML tags : <div class="title">Copy me if you can</div> so I wanna use preg_match to take just "Copy me if you can" I'm using this preg pattern : $preg = "<div class=\"title\">(.+?)</div>"; So I wrote this code $match = preg_match($preg,$content); The browser outputs : Warning: preg_match() [function.preg-match]: Unknown modifier '(' What 回答1: You forgot the

问题 For example it works: {<div\s+class=\"article\"><h2(.*)</div>}s If I do this way, I get nothing: {<div\s+class=\"article\"> <h2(.*) </div>}s I suspect that I should use some modifier, but I know which one from here: http://php.net/manual/en/reference.pcre.pattern.modifiers.php 回答1: That would be the /x modifier: x (PCRE_EXTENDED) If this modifier is set, whitespace data characters in the pattern are totally ignored except when escaped or inside a character class, and characters between an

问题 When I apply x:FieldModifier to my WPF control, eg: <TextBox x:Name="textBox1" x:FieldModifier="Public"/> visual studio (tried on 2008 and 2010) gives me the following error: x:FieldModifier is not valid for the language C# How can I solve this problem? Edit: Sorry, I want to make it public... 回答1: use lower case 'public' not 'Public' <Window x:Class="WpfApplication1.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006

问题 I'm new to using AndEngine and am trying to get a sprite to increase in size on touch . It kind of works, but will suddenly get this error sometimes. Any ideas? At this point, I just need enough text so SO will let me post my question. If anyone needs any more information, let me know and I will post it. I'm very open to ideas. If you have a better way or see a problem with my code, please let me know. At this point, the physics world doesn't even work. 06-17 22:44:25.809: E/AndroidRuntime

问题 Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)? I know there's a "modifiers" property in the properties window so I can set it for each individual control... however I would like to change the project so from now on myself and other developers have to specifically decide to change from private . (Which I would strongly discourage them from doing). I believe there is no way of doing this,

问题 Today, I found something in legacy code. It has "static new" for one function. It looks like this. class Foo { public static void Do() { Console.WriteLine("Foo.Do"); } } class Bar: Foo { public static new void Do() { Console.WriteLine("Bar.Do"); } } I don't understand the static new modifier for the Do method in class Bar . In C#, static method can only be invoked with class name instead of object name. So, I don't think there is any difference between having the "new" and not. Generally, if

问题 I'm beginning to try out SwiftUI and I'm surprised that it doesn't seem to be straightforward to change the background color of a View . How do you do this using SwiftUI ? 回答1: You can do something like: .background(Color.black) around your view. eg. from the default template (I am encompassing it around a Group): var body: some View { VStack { Text("Hello SwiftUI!") } .background(Color.black) } To add some opacity to it, you can add the .opacity method as well: .background(Color.black

问题 First, before I go on, I have read through: SceneKit painting on texture with texture coordinates which seems to suggest I'm on the right track. I have a complex SCNGeometry representing a hexasphere. It's rendering really well, and with a full 60fps on all of my test devices. At the moment, all of the hexagons are being rendered with a single material, because, as I understand it, every SCNMaterial I add to my geometry adds another draw call, which I can't afford. Ultimately, I want to be
