Tips & Tricks:
Please add some!
Sample Code:
Dim pSecDesc, pOldDACL As IntPtr
Dim ea As EXPLICIT_ACCESS
Dim Win32Error As Win32Exception
Dim ret, iPerm As Integer
' get the Security Descriptor and DACL
ret = GetNamedSecurityInfo(strPath, SE_FILE_OBJECT, DACL_SECURITY_INFORMATION, Nothing, Nothing, pOldDACL, Nothing, pSecDesc)
If ret <> 0 Then
Win32Error = New Win32Exception(ret)
Throw New Exception(Win32Error.Message)
End If
' build an explicit access structure
BuildExplicitAccessWithName(ea, strUserName, iPerm, SET_ACCESS, CONTAINER_INHERIT_ACE Or OBJECT_INHERIT_ACE)
