在 vb .net 中,无边框形式会在运行时自动调整大小

border less form gets automatically resized during runtime in vb .net

我使用 vb .net 创建了一个小的无边框表单。该窗体包含三个方形按钮。表格的大小为 (93, 31)。在表单设计期间一切都很好,但是当我 运行 程序时,表单的大小增加到有点像 (98,34)。我什至在表单的自动调整 属性 的 true 和 false 之间切换,以检查它是否是问题的原因,但这确实有帮助。
如何阻止表单调整大小?

编辑:
我通过将表单的 FormBorderStyle 属性 设置为 None

使表单无边框

这是代码

Public Class OSD_Dialog

Dim drag As Boolean
Dim mousex As Integer
Dim mousey As Integer

' The folllowing three subs are helpfull in making the form dragable

  Private Sub Form1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseDown
    drag = True
    mousex = Windows.Forms.Cursor.Position.X - Me.Left
    mousey = Windows.Forms.Cursor.Position.Y - Me.Top
End Sub

Private Sub Form1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseMove
    If drag Then
        Me.Top = Windows.Forms.Cursor.Position.Y - mousey
        Me.Left = Windows.Forms.Cursor.Position.X - mousex
    End If
End Sub

Private Sub Form1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles Me.MouseUp
    drag = False
End Sub

'The following sub is helpful in creating an outline on the border of the form

 Protected Overrides Sub OnPaintBackground(ByVal e As PaintEventArgs)
    MyBase.OnPaintBackground(e)

    Dim rect As New Rectangle(0, 0, Me.ClientSize.Width - 1, Me.ClientSize.Height - 1)

    e.Graphics.DrawRectangle(Pens.White, rect)
End Sub

Private Sub OSD_Dialog_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Me.TopMost = True
    Me.SetStyle(ControlStyles.SupportsTransparentBackColor, True)

    Me.BackColor = Color.Red
    TransparencyKey = BackColor

End Sub

将此添加到您的 Form_Load 活动中:

Me.Size = New Size(93, 31)

还要确保您已在设计时将 AutoScaleMode 设置为 'None'
