我得到Win32Exception - 生成代码中的“类已经存在”。相同的代码在我的演示项目中没有问题。什么可能是一个问题?Win32Exception - 类已经存在
Private Class MyClientWindow
Inherits NativeWindow
Public Sub New(ByVal parent As Form)
Dim cp As CreateParams = New CreateParams()
' Fill in the CreateParams details.
cp.Caption = "Parent Static Window"
cp.ClassName = "Static"
' Set the position on the form
cp.X = 0
cp.Y = 0
cp.Height = 0
cp.Width = 0
' Specify the form as the parent.
cp.Parent = parent.Handle
' Create as a child of the specified parent
cp.Style = WS_CHILD Or WS_VISIBLE
' Create the actual window
Me.CreateHandle(cp)
End Sub
End Class

如果你改变了类名,会发生什么? – jdigital
是的,大写classname使它工作 – walter
