There are two types of software packages: Binary Package and source code package. How do I select a software package that suits my binary format? 1. Select a software package based on the CPU architecture A binary package converts a source program to an Instruction Set suppo

We often read some resource files in the code (compared to slices, music, text, etc.). These simple processes are of course not problematic when running alone. However, if we make the code into a jar package, even if the resource files are packaged together, these things will not be found. Take a look at the following code://Source code 1: PackageEdu.hxraid;ImportJava.io.*; Public classResource { Public voidGetResource ()throwsioexception{File File=N

The concept of package (package) already exists in AS2, which represents a directory structure in the hard disk that is used to classify and store various class files. In AS3 this concept can still be understood as a path, or directory structure, where the name of the package is the directory where your class resides. If the class file and the FLA file are store

Recent projects need to add a dependency in NuGet, but the company's development machine is not net ... Say that you crossing may not believe, do the development of the development machine actually no net .... (then you don't have to leave the flash.) No way, the project needs to throw things into the VS inside, only to find ways to add the dependencies in If there is a net, adding the dependencies inside the NuGet is very simple, and the search comes directly on the line.
