vb 动态生成控件，如何置于顶层
以Command控件为例败罩，把控件的index设置为0 表示控件数组

需要生成新控件的时察茄闹候用Load Command1(1) 生成一个新的Command1 （默认位置与原控件位置相同切默认Visible =false）
设置Command1(1).Visible = True 使其可见
Command1(1).ZOrder 使纳余其置顶
Load Command1(1)
Command1(1).Left = Command1(1).Left + 1000
Command1(1).Visible = True
Command1(1).ZOrder

VB.NET 不同控件重叠时，如何控制某一个在上面。
如果是在设计模式下，在控件上单击右键，有“置于顶层”“置于底层”的选项。
如果对于已经生成好的程序，那么已经在设计模式下添岁带逗加到窗体上的控件是不能够调整显示顺序的，倒是通过 Me.Controls.Add(Me.Controls) 这种方式动态添加的控件可以调整顺序，哪个被先 Add 了，哪个就显示在顶端。
如果对这个比较好奇的话，可以到 Form1.Designer.vb 下找行纳到 InitializeComponent() 这一段，看里面不同的 Me.Controls.Add(Me.Controls) 的顺序乎卖会导致窗体呈现出怎样的结果。
VB.NET如何让弹出的窗体显示在所有的窗体的最前面（包括其他程序打开的窗体）
你可以这样做，尺碧设置窗体的TopMost 属性为真！
Me.TopMost = True
Form.TopMost 属性
获取或设置一个值陵歼举，指示该窗体是否应显改码示为最顶层窗体。
