vb.net 無邊框窗體的問題

設(shè)置窗體的text為空，設(shè)置窗體的controlbox屬性為false，設(shè)置窗體的FormBorderStyle 屬性為Sizable，就可以改變窗體大小了，并且可以在任務(wù)欄點擊。

Vb.net 無邊框窗體如何實現(xiàn)四周陰影？ 網(wǎng)上搜到的都是兩邊陰影的，我需要四周陰影

設(shè)置全局變量：

Dim?drag?As?Boolean

Dim?mousex?As?Integer

Dim?mousey?As?Integer

假設(shè)你想拖動的是Panel1控件，以及此控件上的?Label1（用于顯示標(biāo)題）和PictureBox4（用于顯示圖標(biāo)）：

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里面要使無邊框的窗體有陰影該怎么做

調(diào)用系統(tǒng)API使窗體下?lián)碛嘘幱靶Ч?/p>

using System.Runtime.InteropServices;

然后再窗口類的隨便哪個地方加上：

const int CS_DROPSHADOW = 0x20000;

const int GCL_STYLE = (-26);

//聲明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);

最后在窗體的構(gòu)造函數(shù)中加上：

SetClassLong(this.Handle, GCL_STYLE, GetClassLong(this.Handle, GCL_STYLE) | CS_DROPSHADOW);
