关于数组的API函数的含义

贝隆 2009-05-25 12:30:27
本人想够深的学习一下数组，查询了相关的API函数，具体如下：
但是都没有更多的说明，有谁能帮我说说他们的含义和用法？拜谢！

获取数组元素数据起始地址，第1个参数应该声明成 byval，以下大多数也是如此
psa 的参数含义是数组的注册地址
每次想要操作数组元素之前都应该先用此函数获取数据地址，

安全数组的这些ａｐｉ我很早就研究过了，正好这两天因为项目应用，整理了一些调用，封装了几个函数和几个宏，实现我最常用的１维可变类型的使用，遇到ｌｚ问这个问题，100分太馋了，想蹭蹭

LZ,,看到您的话,我忽然想到了,前些时候有个人跟你发出了差不多的宣言:我想更深刻的学习一下winsock

OK,于是他提问:我从现在开始不再用MS的标准winsock控件,由纯API来完成.

我对他的提议是:如果你真想这么干,那么你必须先深刻的理解一下什么是winsock?winsock是用来干嘛的

MS-winsock中的所有特性你是否已经完全掌握?TCP是什么东西?UDP是什么东西?他们俩在网络世界中充当

着什么样的角色?现在有几种通用的标准协议?这些协议中,又有多少已经在应用层被很好的实施了?



总之一点,,,,,基础很重要!!!!当对某块的技术很感兴趣时,基础,基础很重要!

想学API---网上到处是API用法的文章;

你说的哪本书应该是：VB高级编程吧，比较深奥！
看了一下它关于数组方面的说明，VB的数组定义内部是一个结构，比较高深，所以我想更深层次的了解一下。

至于楼山的仁兄，我只想说谢谢你的回复了，你没有明白我的意思唉！

楼上的不能这样讲，楼主所列出的函数实际上都是在后台帮我们实现在VB中数组一些常用功能的功臣。

VB中的数组都是安全数组，关于安全数组你多看看网络上的VB真想不到系列文章。

不过还有一本国外人写得比较高深的书里对这个也有专门的讲解，不记得啥名字了。

Public Declare Sub SafeArrayAllocDescriptorEx Lib "oleaut32.dll" (ByVal vtas integer, ByVal cDims As Long, ByRef ppsaOut As SAFEARRAY)
以上这几个好像是，申请空数组然后由用户自己设置数据的方法

Public Declare Sub SafeArrayCopy Lib "oleaut32.dll" (ByRef psa As SAFEARRAY, ByRef ppsaOut As SAFEARRAY)
Public Declare Sub SafeArrayCopyData Lib "oleaut32.dll" (ByRef psaSource As SAFEARRAY, ByRef psaTarget As SAFEARRAY)

Public Declare Sub SafeArrayDestroy Lib "oleaut32.dll" (ByRef psa As SAFEARRAY)
Public Declare Sub SafeArrayDestroyData Lib "oleaut32.dll" (ByRef psa As SAFEARRAY)
Public Declare Sub SafeArrayDestroyDescriptor Lib "oleaut32.dll" (ByRef psa As SAFEARRAY)
销毁数组，销毁数据，销毁描述信息

Public Declare Function SafeArrayGetDim Lib "oleaut32.dll" (ByRef psa As SAFEARRAY) As Long
获取维数
Public Declare Sub SafeArrayGetElement Lib "oleaut32.dll" (ByRef psa As SAFEARRAY, ByRef rgIndices As Long, pv As Any)

元素长度
Public Declare Sub SafeArrayGetIID Lib "oleaut32.dll" (ByRef psa As SAFEARRAY, ByRef pguid As GUID)
这个和对象类型元素有关

Public Declare Sub SafeArrayUnlock Lib "oleaut32.dll" (ByRef psa As SAFEARRAY)

有一些东西的用途不是很大，就没说，特别是针对 recordinfo 的，如果想单独通过api方式使用，很麻烦
