vb.net 怎样将窗体和所有控件根据电脑分辨率固定？
Public Class Form1
Dim 初始化控件自动大小调整与窗口的宽度比例 As Integer
Dim 初始化控件自动大小调整与窗口的高度比例 As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
初始化控件自动大小调整与窗口的宽度比例 = Me.Width / 控件自动大小调整.Width
初始化控件自动大小调整与窗口的高度比例 = Me.Height / 控件自动大小调整.Height
显示控件的位置坐标()
End Sub
Private Sub Form1_ResizeEnd(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.ResizeEnd
' Form1_ResizeEnd 这个事件是 窗口大小变化完成后 再进行操作的
控件自动大小调整.Location = New Point(控件自动大小调整.Left, 控件自动大小调整.Top)
'设置控件的初始左位置坐标 与 上位置坐标
控件自动大小调整.Size = New Point(Int(Me.Width / 初始化控件自动大小调整与窗口的宽度比例), Int(Me.Height / 初始化控件自动大小调整与窗口的高度比例))
'更改控件的大小 按第一次窗口的比例 进行调整
显示控件的位置坐标()
End Sub
Private Sub 显示控件的位置坐标()
Label1.Text = "控件的上边距坐标： " 控件自动大小调整.Top
Label2.Text = "控件的左边距坐标： " 控件自动大小调整.Left
Label3.Text = "控件的宽度大小： " 控件自动大小调整.Width
Label4.Text = "控件的高度大小： " 控件自动大小调整.Height
End Sub
End Class

Q2: vb.net保存图片时如何调整其分辨率
保存前加一句 myImage2.SetResolution(300, 300) 你设置的bMape不是保存的主画布 所以无效，设置分辨率就是 SetResolution（X,Y）
