如何移动VB中的无边框窗体
1、无边框窗体也就是无标题栏窗体，对于这样的窗体移动需要编程实现。
2、vb有两种办法实现，一直接编程实现，二调用windows API编程实现。
3、这里示例直接编程实现：
Option Explicit
Dim BolIsMove As Boolean, MousX As Long, MousY As Long
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then BolIsMove = True
MousX = X
MousY = Y
End Sub
Private Sub Form_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim CurrX As Long, CurrY As Long
If BolIsMove Then
CurrX = Me.Left - MousX + X
CurrY = Me.Top - MousY + Y
Me.Move CurrX, CurrY
End If
End Sub
Private Sub Form_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
BolIsMove = False
End Sub
vb.net 无边框窗体的问题
设置窗体的text为空，设置窗体的controlbox属性为false，设置窗体的FormBorderStyle 属性为Sizable，就可以改变窗体大小了，并且可以在任务栏点击。
怎么用VB/VB.net/C#修改一个其他程序的窗口的边框样式？
private const int GWL_STYLE = (-16);
private const int GWL_EXSTYLE = (-20);
private const uint WS_EX_LAYERED = 0x80000;
private const uint WS_EX_TRANSPARENT = 0x20;
private const uint WS_THICKFRAME = 262144;
private const uint WS_BORDER = 8388608;
/// summary使指定 「 see cref="IntPtr"/ 句柄」 窗体 边框样式变为无边框。/summary
public static uint 无边框窗体(IntPtr 句柄) {
uint style = API_窗口.GetWindowLong(句柄, GWL_STYLE);
style = ~WS_BORDER;
style = ~WS_THICKFRAME;
return API_窗口.SetWindowLong(句柄, GWL_STYLE, style); ;
}
API窗口静态类
[DllImport("user32", EntryPoint = "SetWindowLong")]
public static extern uint SetWindowLong(IntPtr hwnd, int nIndex, uint dwNewLong);
[DllImport("user32", EntryPoint = "GetWindowLong")]
public static extern uint GetWindowLong(IntPtr hwnd, int nIndex);
修改窗口位置
/// summary

/// /summary
/// param name="hWnd"/param
/// param name="hWndInsertAfter"用于标识在z-顺序的此 CWnd 对象之前的 CWnd 对象。
/// para/para如果uFlags参数中设置了SWP_NOZORDER标记则本参数将被忽略。可为下列值之一：
/// para/paraHWND_BOTTOM：值为1，将窗体置于Z序的底部。如果参数hWnd标识了一个顶层窗体，则窗体失去顶级位置，并且被置在其他窗体的底部。
/// para/paraHWND_NOTOPMOST：值为-2，将窗体置于所有非顶层窗体之上（即在所有顶层窗体之后）。如果窗体已经是非顶层窗体则该标志不起作用。
/// para/paraHWND_TOP：值为0，将窗体置于Z序的顶部。

VB.net怎样按住鼠标移动无边框窗体
当用户按下左键时，为按下对象的MouseMove事件绑定处理方法，并记录鼠标坐标（窗体左上角为原点，在事件的MouseEventArgs类型的e参数中提供）。此时用户移动鼠标，保持窗体原点与鼠标新坐标的相对位置不变。当用户释放左键时，撤销按下对象的MouseMove事件处理方法
如何改变vb.net程序的边框样式？
如果要做漂亮的界面的话，我建议你用WPF来做。所有的控件都可以用模板来定义样式。
虚线的话，只需要定义一个矩形，设置一个属性就可以了。前提是，WPF应用程序只能用VS2008或者VS2010来做
