问题 I'm struggling in a Flutter situation with multiple navigators. Concept here is a page which triggers a modal with his own flow of multiple pages. Inside the modal everything is going swiftly (navigation pushes/pops are working), but if the modal is dismissed it removes every page of the lowest navigator.

I have a website in PHP, and obviously, HTML, CSS, JS, etc. What I want to do is to allow users to full-screen certain pieces of the DOM. So my question is, is there any way to wrap flash around certain portions of the DOM dynamically in order to allow full screening of that portion. Edit: The current responses are very interesting and could be the only options. But in my ideal world there would be an embedded flash object, and

问题 How can i display different labels under each column and also have another label for the entire group? As you can see in the picture below i want to use fontawesome icons for each column but another label for the main group. I found other answers how to use fa icons but don't know how to position them under each bar.

问题 I have function that will return all of rows, but I expect 0 or 1 because Sid is unique: CREATE DEFINER=`root`@`localhost` FUNCTION `IsInDatabase`(sId VARCHAR(21)) RETURNS tinyint(1) BEGIN RETURN (SELECT COUNT(Id) FROM table WHERE SId =sid); END When executed directly, SELECT COUNT(Id) FROM table WHERE SId ='87882118' will return exactly what I need: '1' or '0'.
