VB未公开的三个函数ObjPtr,StrPtr,VarPtr

'Form Code:

'ObjPtr: 返回对象实例私有域的地址
'StrPtr: 返回字符串第一个字的地址
'VarPtr: 返回变量的地址

'使用对象浏览器（Object Browser），你可以发现更多其他对象未公开的细节。


'使用诸如金山游侠之类的游戏修改器可以跟踪到这个变量的地址(查99887766数值)

Private Sub Form_Load()
'为了能持久显示,便于查看
Me.AutoRedraw = True

'VarPtr用在包含字符串的变量时,可能返回的指针是临时地址(UNICODE转换的缘故)
'StrPtr还是唯一能直观地告诉你空字符串和null字符串的不同的方法。
'对于null字符串(vbNullString)，StrPtr的返回值为0，而对于空字符串，函数的返回值为非零

'如果成功的话，代表这个程序的任务 ID，若不成功，则会返回 0。

'语法
'Shell(pathname[,windowstyle])

'Shell 函数的语法含有下面这些命名参数:

'部分 描述
'pathname 必要参数。Variant (String)，要执行的程序名，以及任何必需的参数或命令行变量， _
可能还包括目录或文件夹，以及驱动器。
'Windowstyle 可选参数。Variant (Integer)，表示在程序运行时窗口的样式。 _
如果 windowstyle 省略，则程序是以具有焦点的最小化窗口来执行的。


'windowstyle 命名参数有以下这些值:
'常数 值 描述
'vbHide 0 窗口是隐藏的，并且焦点被传递给隐藏窗口。
'vbNormalFocus 1 窗口拥有焦点，并且恢复到原来的大小与位置。
'vbMinimizedFocus 2 窗口缩小为图符并拥有焦点。
'vbMaximizedFocus 3 窗口最大化并拥有焦点。
'vbNormalNoFocus 4 窗口被恢复到最近一次的大小与位置。当前活动窗口仍为活动窗口。
'vbMinimizeNoFocus 6 窗口缩小为图符。当前活动窗口仍为活动窗口。

"!"感叹号与"."圆点的用法差异

都用在对象的属性等的引用上.

圆点操作符"."用来表示对象的属性和方法,在引用时需要用在对象的名称、圆点和需要的属性和方法.例如引用按钮的Caption属性:Command1.Caption

感叹号"!"常用于一个控件作为一个特性访问的情况下,例如引用另一窗体中的TextBox的Text属性:Form2!Text1.Text,用"!"连接两个控件,且前者是后者的容器.值得注意的是这里如果使用"."替换"!",可以获得同样效果.为了提高代码可读性,用"!"吧.

VB的坐标系统综述

由于在visualbasic系统中有多种坐标定义,容易使初学者混淆,本文将详细总结vb的坐标系统的一些基本概念，并提供坐标定义的详细方法：

visual basic 坐标系统概述：

visual basic的坐标系统是指在屏幕（screen）、窗体(form)、容器(container)上定义的表示图形对象位置的平面二维格线，一般采用数对（x,y）的形式定位。其中，x 值是沿 x 轴点的位置，最左端是缺省位置 0。y 值是沿 y 轴点的位置，最上端是缺省位置 0。

在visualbasic坐标系中，沿坐标轴定义位置的测量单位，统称为刻度，坐标系统的每个轴都有自己的刻度。坐标轴的方向、起点和刻度都是可变的,在后面的叙述中，将讨论如何改变这些定义。

如何创建坐标系统:

创建图形对象的坐标系统，一般有以下几种方法：

1、使用系统缺省定义：

在系统缺省状态下，visualbasic使用twips坐标系，以’缇’为单位(1缇的长度等于1/1440英寸；1/567厘米;1/20磅)。应当注意的是：这些值指示的是图形对象打印尺寸的大小。而在计算机屏幕上的物理距离则根据监视器的大小及分辨率的变化而变化。

2、选择系统标准刻度定义：

除了缺省的twips坐标系外，用户还可以通过对象的scalemode属性来设置其它的坐标刻度：（共有8种设置），现将这些设置列表如下：

scalemode值 表示 说明

0 user 用户自定义

1 twip 缇，系统缺省设置

2 point 磅，每英寸约为72磅

3 pixel 像素，像素是监视器或打印机分率的最小单位。每英寸里像素的数目由系统设备的分辨率决定。

4 character 字符，打印时，一个字符高 1/6 英寸，宽1/12 英寸

5 inch 英寸，每英寸为2.54厘米

6 millimeter 毫米

7 centimeter 厘米　

在上述设置值中，除了 0 和 3以外，其它所有模式都是打印机所打印的单位长度。例如，某对象长为4个单位，当 scalemode 设为5 时，打印时就是4英寸长。在程序中设定scalemode值的代码如下：

'设窗体的刻度单位为厘米。

scalemode = 7

'设 picture1 的刻度单位为像素。

picture1.scalemode = 3

3、创建自定义坐标系统：

当scalemode=0时，即为用户自定义模式，可采用设置对象的相应属性，来创建所需的坐标系统,这些属性是：

scaleleft: 设置对象左边距值

scaletop: 设置对象上边距值

scalewidth: 设置对象宽度

scaleheight: 设置对象高度

下面给出如下设置代码：

scaleleft=100

scaletop=100

scalewidth=300

scaleheight=200

picture1.scaleleft=50

picture1.scaletop=50

则所定义的坐标系如下图所示：

scaletop=100

picture1.scaleleft=50

以上代码定义窗体左上角坐标为（100，100），定义窗体内图形对象picture1距窗体左边距离为50，上边距离为50。scalewidth 和 scaleheight 语句定义窗体内部宽度的 1/300 为水平坐标单位；当前窗体内部高度的 1/200为垂直坐标单位。如果窗体的大小以后被调整，这些单位保持原状。也就是说：scalewidth 和 scaleheight是按照对象的内部尺寸来定义单位的，并且这些尺寸不包括边框厚度或菜单标题的高度。scalewidth 和 scaleheight是指对象内的可用空间的大小。它们决定了对象本身的坐标系统。这有别于内部尺寸和外部尺寸（由 width 和height属性指定）定义，width 和 height总是按照容器的坐标系统来表示。另外以上刻度属性都可包括分数，也可是负数。如果将 scalewidth 和 scaleheight属性设置值为负数即改变坐标系统的方向。

4．使用scale方法定义坐标系统：

一个更简洁的改变坐标系统的途径是使用 scale 方法。定义形式如下：

[object.]scale (x1, y1) – (x2, y2)

x1 和 y1 的值，决定了 scaleleft 和 scaletop 属性的设置值。x2-x1的差值和y2-y1的差值，分别决定了scalewidth 和 scaleheight 属性的设置值。若指定 x1 > x2 或 y1 > y2 的值，与设置scalewidth 或 scaleheight 为负值的效果相同。例如：设定窗体坐标系统如下：

scale (100, 100)-(200, 200)

该语句定义等同于以下属性设置：

scaletop=100:scaleleft=100:scalewidth=100:scaleheight=100

如何恢复缺省坐标系统：

在定义了其它坐标系后，如果需要将坐标系统恢复为缺省的twips坐标系，可以使用不含参数的scale方法，如语句：

picture1.scale

将图形对象的坐标系统恢复为缺省，其左上角坐标为（0，0）。
