effect is as follows:Most text font-size are 12px, and only one inline non-replacement element has a text size of 24px. However, the line-height of all text is 12px, because Line-heght is an inherited property. Therefore the line-height of the strong element is also 12px.Because the top of the inline box is inside the element content area, the content of the element falls outside the line box and actually overlaps with the other row boxes. As a result, the lines of text look very irregular.Psty

subroutine Nested(20) Console.WriteLine(x);End Sub Nested functions can access variables in external processes. This feature is calledClosure. With Closure, we can generate functions with variable rules to achieve latency computing. This is a basic function of FP. Closure, an embedded function of VB9, may be implemented by using the Tuple feature. However, there is no further computing on the principle. Compared with C # anonymous functions, VB

In VB, the MDI (Multiple document interface, multi-window program) Form is defined: "The MDI form acts as a background window for a program that contains a form with the MDIChild property to True." In a VB program, there can be at most one MDI parent form and multiple MDI child forms, and the way to create an MDI parent form is to select "New MDI Form" in the VB File menu. When the MDI program runs, if the child window has a menu, the child window's menu automatically replaces the parent Window

Basic concepts of Events-Beginning Visual C #, A trigger condition is required for an event, such as timed occurrence, Mouse clicking, and the event itself.
