VB.NET中的Aero Snap [英] Aero Snap in VB.NET
问题描述
我正在创建一个类似于在VB.Net中为表单添加自定义外观的应用程序 [ ^ ]但可以更多功能.
我坚持的一件事是Aerosnap.在VB.NET中有没有一种方法可以使Aerosnap像在Photoshop或iTunes中一样工作?

One thing I''m stuck on is Aerosnap. Is there a way in VB.NET to make Aerosnap work like in Photoshop or iTunes?

公共课程表格1
''从dwmapi.dll导入函数-从sdk dwmapi.h获取此信息

公共共享的子DwmExtendFrameIntoClientArea(ByVal hWnd作为System.IntPtr，ByRef pMargins作为页边距)
结束子

Public Shared Sub DwmIsCompositionEnabled(ByRef IsIt as Boolean)
结束子
''创建可以解决Alpha透明度问题的画笔
专用DWMFrame作为SolidBrush =新的SolidBrush(颜色.黑色)
昏暗的BlurBehind为Boolean = False

昏暗的模糊为Boolean = False
''创建Margins结构的实例以在我们的表单中使用
专用插图作为保证金=新保证金

''将边距设置为其默认值
inset.Top = 40
inset.Left = 0
inset.Right = 0
inset.Bottom = 0
''检查DWM是否已启用.这是一种非常愚蠢的检查方法，因为它仍然需要dwmapi.dll的存在...
Dim isit As Boolean = False
DwmIsCompositionEnabled(isit)
如果是那么
''如果启用了DWM，则调用给我们玻璃的函数，并传递一个对我们的插图边距的引用
DwmExtendFrameIntoClientArea(Me.Handle，inset)
其他
''如果未启用DWM，请大喊大叫
MessageBox.Show(未启用DWM")
