vb.net读取txt的数据作图问题

一、分析：

创新新互联，凭借十年的网站设计、做网站经验，本着真心·诚心服务的企业理念服务于成都中小企业设计网站有1000多家案例。做网站建设，选成都创新互联。

1，这一类随时间而变化的曲线图，通常把横轴作为时间，把纵轴作为相应的值，在这里就是密度值。

2，点的集合就是线；一组时间、密度值，对应一个点，把点连接起来就构成了线。

二、在VB.NET中作图，需要知道并解决几个问题：

1，与VB6一样，VB.NET中默认的坐标系统，左上角为坐标原点，X轴的正向为从左向右，Y轴的正向是从上向下。

为了使得它与数学中的坐标系统相一致，可以使用VB.NET中Graphics类的两个方法；

1、TranslateTransform----平移变换

格式：Graphics.TranslateTransform(dx,dy)

其中：dx 和 dy分别是Single数据类型

2、ScaleTransform----缩放变换

格式：Graphics.ScaleTransform(sx,sy)

其中：sx 和 sy分别是Single数据类型；

例如：为了符合数学中的一般格式，可以使用下述代码：

Graphics.ScaleTransform(1, -1)

这样就把Y轴的正方向给翻过来了。

三、VB.NET中绘制图形

1，绘制圆或椭圆

'绘制图形的三步曲

'1，获得一个Graphics对象

Dim MyGraphics As Graphics

MyGraphics = Me.CreateGraphics

'2，定义一个Pen对象，用于绘制图形（轮廓线）

Dim MyPen As New Pen(Color.Black)

'3，定义一个Brush对象，用于填充图形（如果需要填充的话）

Dim MyBrush As New SolidBrush(Color.Orange)

'绘制一个实心圆，该圆在：直线x=200，y=200，x=200+100，y=200+100所划的矩形区域内

MyGraphics.FillEllipse(Brush, 200, 200, 100, 100)

'绘制一个空心圆，该圆在：直线x=200，y=200，x=200+100，y=200+100所划的矩形区域内

MyGraphics.DrawEllipse(Pen, 200, 200, 100, 100)

注意：最后两个数值如果不等，就是绘制椭圆

当圆足够小，就是点了。

2，绘制直线

'1，获得一个Graphics对象

Dim MyGraphics As Graphics

MyGraphics = Me.CreateGraphics

'2，定义一个Pen对象，用于绘制图形（轮廓线）

Dim MyPen As New Pen(Color.Black)

MyGraphics.DrawLine(MyPen, 200, 200, 100, 100)

'或者直接用

Me.CreateGraphics.DrawLine(New Pen(Color.Black), 50, 50, 200, 200)

如何在VB.net中用程序控制鼠标移动和点击

调用api

在Visual Baisc.net中的声明：

Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

Public Const MOUSEEVENTF_LEFTDOWN = H2 '模拟鼠标左键按下

Public Const MOUSEEVENTF_LEFTUP = H4 ’模拟鼠标左键释放

Public Const MOUSEEVENTF_MIDDLEDOWN = H20 '模拟鼠标中间键按下

Public Const MOUSEEVENTF_MIDDLEUP = H40 '模拟鼠标中间键释放

Public Const MOUSEEVENTF_RIGHTDOWN = H8 '模拟鼠标右键按下

Public Const MOUSEEVENTF_RIGHTUP = H10 '模拟鼠标右键释放

Public Const MOUSEEVENTF_MOVE = H1 '模拟鼠标指针移动

例：

mouse_event MOUSEEVENTF_LEFTDOWN,10,10,0,0

'在（10，10）模拟鼠标左键按下

VB.net可以开发小型3D图形显示软件吗？

可以借助DirectX来编程。免费3D引擎可不好找，一般来说速度比不上硬件加速后的DX，尤其令人头疼的是一般都没有针对VB的文档，LZ有这方面理想的话，自己写一个吧……

我不得不承认在VB上写DirectX的教程相当难找！如果LZ想深入研究三维图形问题，C++一定要学，就算不能用C++编程，起码要能把C++程序翻译成VB程序。

我自己学会DX编程花了两三个月（很浅）。编这样一个程序难度是有点大的。

工具：DirectX9和其针对VB的库(项目-添加引用。.NET库里DX库一般都有)，VB不知道现在支不支持DX10以上的版本，不过9绝对够用了。

思路：一切3D图形都是由三角形拼成的。矩形挖掉一个圆孔可不是一个方便画的图形，我估计至少得有24个三角形。你需要记录这些点的坐标，或者干脆把它们写在文件里，到时读出来。

这是我的一个老DX程序的不完全的代码(显示一个黑乎乎的平面)，不一定能编译，可以参考一下。
