addition, in Netscape, the second click is always handled separately before DblClick. Anyway, the warning box is very dangerous here. So make sure your click and DblClick are well separated to avoid a lot of complicated things. Mousemove The MouseMove event works well, but it is important to note that it may require a lot of system resources to handle all the MouseMove events. When the user moves the mouse over a pixel, the mousemove is triggered once. Even if nothing happens, long and comple

Topic:Suppose you have a boring task to find all the phone numbers and email addresses in a long page or article. If you turn pages manually, you may need to look for a long time. If you have a program that can find the phone number and e-mail address in the text of the Clipboard, just press Ctrl-a to select all the text, press Ctrl-c to copy it to the Clipboard, and then run your program. It will replace the text in the Clipboard with the phone number and e-mail address found.Test textSkip to m
