escaping

问题 In code I have developed some years ago I have been using this a lot to close the current form on pressing the Escape key at any moment: procedure TSomeForm.FormKeyPress(Sender: TObject; var Key: Char); begin if key = #27 then close; end; This behaviour is defined for the TForm. The form's KeyPreview property is be set to True to let the form react to key presses before any other components. It all works perfectly well for the best part of the program, however, when the Escape key is pressed

问题 I'm trying to insert a {@code } annotation in a Javadoc comment using Netbeans 8.0 and it's not working properly. I've seen other questions on this from before (i.e., How can you escape the @ character in javadoc?) but the html escape @ and {@literal @} both don't seem to work. My comment looks like this (using both methods for sake of the example): /** * blah blah blah * <p> * For example: * <pre> * {@code * {@literal @}begin_specification * ... * @end_specification * } * </pre> */ I can hit

问题 I was looking at the escape sequences for characters in strings in c++ and I noticed there is an escape sequence for a question mark. Can someone tell me why this is? It just seems a little odd and I can't figure out what ? does in a string. Thanks. 回答1: It's to keep a question mark from getting misinterpreted as part of a trigraph. For example, in "What??!" The "??! would be interpreted as the | character. So, you have to escape the question marks as follows: "What\?\?!" Example complements

问题 I am trying to search for the string ** in a column in a worksheet, but I have trouble making this work as * also works as a wildcard when using find. To complicate it further the same column also includes *, so I need to find ** specifically. I have tried the below code so far, and in both cases it appears to find the first non-empty cell, which happens to be *. Set searchRange = Workbooks(fileName).Worksheets(1).Range("B:B").Find(Chr(42) & Chr(42), LookAt:=xlWhole) Alternatively: Set

问题 The secrete API key I want to store in my environment file for my express server is ignoring half of it as it contains a # symbol in the middle. I can't regenerate the key. And do not want it to be left unsequre 回答1: i do not think it's because of the # symbol. It is only treated as signaling a comment when encountered as first chartacter in a line... you can try this yourself. create a .env file with the following content: a=#b c="#d" #e=f now run `node -e 'console.log(require("dotenv")
