问题 I want to call the <proguard> task in Ant and need to pass it the paths to various JAR files, e.g. the equivalent of: <proguard> -injars /some/path/jar1;/some other path/jar2 </proguard> Problem is, some of these path may contain spaces or special characters, they have to be quoted like this as explained in the proguard manual: <proguard> -injars /some/path/jar1;"/some other path/jar2" </proguard> It doesn't work to quote the whole argument, the individual paths need to be quoted separately.

问题 I notice that when I INSERT and SELECT values to and from a database I have to surround the fields with single quotes, like so: mysql_query("INSERT INTO employees (name, age) VALUES ('$name', '$age')"); However, if I were to update the age, I would not use single quotes: mysql_query("UPDATE employees SET age = age + 1 WHERE name = '$name'"); Also, it seems when adding the date to a SQL database I do not have to surround it with single quotes either: mysql_query("INSERT INTO employees (name,

问题 I have a string like this: This <span class="highlight">is</span> a very "nice" day! What should my RegEx-pattern in VB look like, to find the quotes within the tag? I want to replace it with something... This <span class=^highlight^>is</span> a very "nice" day! Something like <(")[^>]+> doesn't work :( Thanks 回答1: It depends on your regex flavor, but this works for most of them: "(?=[^<]*>) EDIT: For anyone curious how this works. This translates into English as "Find a quote that is

问题 can not find this option in new studio (2010) 回答1: As far as I know this isn't built in to VS2010 - an add-in such as Visual Assist (and you've already mentioned Resharper yourself) will get this for you. Of course, that won't help for the Express versions of VS2010 since add-ins aren't supported in those SKUs. 回答2: Options- Text Editor- HTML- Formatting- Insert attributes values quotes when typing 回答3: This is probably because you need to download it first, then install it.

问题 Ok, this is bit of an obscure question, but hopefully someone can help me out with it. The system I'm working on builds a dynamic SQL string for execution inside a stored procedure, and part of that dynamic SQL defining column aliases, which themselves are actually values retrieved from another table of user generated data. So, for example, the string might look something like; SELECT table1.Col1 AS "This is an alias" FROM table1 This works fine. However, the value that is used for the alias

问题 Is it possible to split a string and to avoid the quotes(single)? I would like to remove the single quotes from a list(keep the list, strings and floats inside: l=['1','2','3','4.5'] desired output: l=[1, 2, 3, 4.5] next line works neither with int nor float l=[float(value) for value in ll] 回答1: To get int or float based on what each value looks like, so '1' becomes 1 and "1.2" becomes 1.2 , you can use ast.literal_eval to convert the same way Python's literal parser does, so you have an
