VB.net，在模块中怎样引用到窗体中的控件

在模块中引用到窗体中的控件，必须在该控件名之前由相应的窗体名作为前导，例如：

创新互联公司是一家专注于成都网站设计、成都网站制作与策划设计,吉利网站建设哪家好?创新互联公司做网站,专注于网站建设十多年,网设计领域的专业建站公司;建站业务涵盖:吉利等地区。吉利做网站价格咨询:13518219792

1，要引用窗体Form1中的控件TextBox1

MsgBox(Form1.TextBox1.Text)

2，要引用窗体Form2中的控件TextBox1

MsgBox(Form2.TextBox1.Text)

在VB.NET中实现插件架构

目前没看到vb.net

不过C#也是一样的 原理都差不多，看看就会了

vb.net的WinForm窗体程序中，ListView,DataGridView,还是什么控件能达到这种显示效果？

DataGridView 应该是可以的，你可以调协,DataGridView的背景为黑色。单元格的前景色为白色，，特殊列的单元格可以设置成你需要的颜色！
