然后再窗口类的随便哪个地方加上:
const int CS_DROPSHADOW = 0x20000;
const int GCL_STYLE = (-26);
//声明Win32 API
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int SetClassLong(IntPtr hwnd,int nIndex,int dwNewLong);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
public static extern int GetClassLong(IntPtr hwnd, int nIndex);
最后在窗体的构造函数中加上:
SetClassLong(this.Handle, GCL_STYLE, GetClassLong(this.Handle, GCL_STYLE) | CS_DROPSHADOW);
Vb.net 无边框窗体如何实现四周阴影? 网上搜到的都是两边阴影的,我需要四周阴影
设置全局变量:
Dim drag As Boolean
Dim mousex As Integer
Dim mousey As Integer
假设你想拖动的是Panel1控件,以及此控件上的 Label1(用于显示标题)和PictureBox4(用于显示图标):
Private Sub TitleMove_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseDown, Label1.MouseDown, PictureBox4.MouseDown
drag = True
mousex = Windows.Forms.Cursor.Position.X - Me.Left
mousey = Windows.Forms.Cursor.Position.Y - Me.Top
End Sub
Private Sub TitleMove_MouseMove(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseMove, Label1.MouseMove, PictureBox4.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 TitleMove_MouseUp(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles Panel1.MouseUp, Label1.MouseUp, PictureBox4.MouseUp
drag = False
End Sub
VB.NET窗体阴影
vb.net2008
vb.net API 是将除特殊变量(如H20000)的Long都改成Integer
窗体的右侧和下方有阴影
Public Class Form1
Private Const CS_DROPSHADOW = H20000
Private Const GCL_STYLE = (-26)
Private Declare Function GetClassLong Lib "user32" Alias "GetClassLongA" (ByVal hwnd As Integer, ByVal nIndex As Integer) As Integer
Private Declare Function SetClassLong Lib "user32" Alias "SetClassLongA" (ByVal hwnd As Integer, ByVal nIndex As Integer, ByVal dwNewLong As Long) As Integer
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
SetClassLong(Me.Handle, GCL_STYLE, GetClassLong(Me.Handle, GCL_STYLE) Or CS_DROPSHADOW)
End Sub
End Class
