[DllImport("user32.dll", EntryPoint = "SetParent")] 
public static extern int SetParent(int hWndChild, int hWndNewParent); 

[DllImport("user32.dll", EntryPoint = "FindWindow")] 
public static extern int FindWindow(string lpClassName, string lpWindowName); 

public Form1()

} 

以上在win7以下系统基本正常，在win7里会出现界面不出的现像。

下面这段可用，进行了系统判断。
