问题 How can I sync the scrolling of two multiline textboxes in C# (WinForms)? When you scroll up/down a line in TextBox A, TextBox B should scroll up/down too. The same the other way around. Is this achievable without custom controls? 回答1: Yes, you'll have to create a custom text box so you can detect it scrolling. The trick is to pass the scroll message to the other text box so it will scroll in sync. This really only works well when that other text box is about the same size and has the same

How to enter a multi-line command

Is it possible to split a PowerShell command line over multiple lines? In Visual Basic I can use the underscore ( _ ) to continue the command in the next line. You can use a space followed by the grave accent (backtick): Get-ChildItem -Recurse ` -Filter *.jpg ` | Select LastWriteTime However, this is only ever necessary in such cases as shown above. Usually you get automatic line continuation when a command cannot syntactically be complete at that point. This includes starting a new pipeline element: Get-ChildItem | Select Name,Length will work without problems since after the | the command

问题 How can I modify the gap between lines (line spacing) in a multiline UILabel ? 回答1: Edit: Evidently NSAttributedString will do it, on iOS 6 and later. Instead of using an NSString to set the label's text, create an NSAttributedString , set attributes on it, then set it as the .attributedText on the label. The code you want will be something like this: NSMutableAttributedString* attrString = [[NSMutableAttributedString alloc] initWithString:@"Sample text"]; NSMutableParagraphStyle *style = [

Multiple lines of text in UILabel

问题 Is there a way to have multiple lines of text in UILabel like in the UITextView or should I use the second one instead? 回答1: I found a solution. One just has to add the following code: // Swift textLabel.lineBreakMode = .ByWordWrapping // or NSLineBreakMode.ByWordWrapping textLabel.numberOfLines = 0 // For Swift >= 3 textLabel.lineBreakMode = .byWordWrapping // notice the 'b' instead of 'B' textLabel.numberOfLines = 0 // Objective-C textLabel.lineBreakMode = NSLineBreakByWordWrapping;

Regular expression matching a multiline block of text

问题 I\'m having a bit of trouble getting a Python regex to work when matching against text that spans multiple lines. The example text is (\'\\n\' is a newline) some Varying TEXT\\n \\n DSJFKDAFJKDAFJDSAKFJADSFLKDLAFKDSAF\\n [more of the above, ending with a newline]\\n [yep, there is a variable number of lines here]\\n \\n (repeat the above a few hundred times). I\'d like to capture two things: the \'some_Varying_TEXT\' part, and all of the lines of uppercase text that comes two lines below it
