locate object

Use gdb to quickly locate the "segment error" and gdb to locate the segment Error Sometimes, when we operate on an invalid memory in a section of C/C ++ code, the "Segmentation fault (core dumped) "-- segment error. I think many people will often encounter this problem. This problem is very speechless, just prompts "segment error", and then there is nothing. If we blindly look at the code to find it too p

Locate and z-index, locate z-index Positioning Location used to control the element The positioning keyword is position and position has four values: relative, absolute, static, and fixed. After the element is located, the element has four values available: left, right, top, bottom. I will use the following examples to demonstrate the absolute location of absolute and relative location of relative. 1. I def

. Before we formally start using XPath for positioning, let's first understand what XPath is. XPath is the abbreviation for XML path, because the HTML document itself is a standard XML page, so we can use XPath syntax to locate page elements.Suppose we now take the HTML code shown in figure (2) as an example, to refer to the corresponding object, the XPath syntax is as follows:Figure (2)Absolute path notati

XPath syntax to locate page elements.Suppose we now take the HTML code shown in figure (2) as an example, to refer to the corresponding object, the XPath syntax is as follows:Figure (2)Absolute path notation (only one), written as follows:Reference the form element on the page (that is, line 3rd in the source code):/html/body/form[1]Note: 1. The XPath absolute path of the element can be queried directly by

Usually we locate files are located by absolute path, such as "F:/java/bin/test/test.java", the disadvantage is that once the project files moved, these paths are completely invalidated.So, let's describe a way to locate a file through a relative path. The IDE I used is eclipse, the project path has src and bin folders stored separately, Java source code and compiled files., my project name is Project, in t
