using System.Runtime.InteropServices;

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 窗体四周阴影效果

它们的窗体实际上就是你截图出来的大小，周围的阴影效果都是自己画出来的。

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

VB.net 过滤文字

dim a as string = replace(trim(textbox1.text),"TMD","") 'a 是过滤后的字符串，没有"TMD"，

还有：if textbox1.text.indexOf("TMD") -1 then exit sub

就这个之类的

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

请问VB.NET里面改textbox文字颜色（forecolor）和背景颜色(backcolor)怎么弄？有具体的题目！！

Private Sub CheckBox1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged

If CheckBox1.Checked = True Then

TextBox1.ForeColor = Color.Red

Else

TextBox1.ForeColor = Color.Black

End If

End Sub

Private Sub CheckBox2_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CheckBox2.CheckedChanged

If CheckBox2.Checked = True Then

TextBox1.BackColor = Color.Yellow

Else

TextBox1.BackColor = Color.White

End If

End Sub
