Code conversion problem

Question

User559005402 posted

Given this code:

		Private Function BackToParentMenu(ByVal mnu As Menu) As Boolean
			' 
			If mnu.parentMenu = lstMenus(0) Then
				Return False
			End If
			For Each mi As MenuItem In mnu.lstMenuItems
				If mi.mousePos.X <> -1 AndAlso (mi.mousePos.X < mnu.Width * 15 / 100) Then
					Return True
				End If
			Next
			Return False
		End Function

 What does it mean when on the first IF it says

 "Operator '=' is not defined for types 'SilverlightApplication1.glMenu.Menu'"?

 

Thanks

For reference types in VB, you need to use "Is" to compare them, not "=" (and "IsNot" instead of "<>").

I don't have a Silverlight Project currently wired up with that object type (Menu I believe), but see if the 'parentMenu' item exposes an 'Equals' method like below:

If mnu.parentMenu.Equals(lstMenus(0)) Then 

 

The previous comments were correct about Reference types in VB.NET, but do not confuse for your code snippet about your '<>' comparison.  That does not need to be changed as mousePos.'X' is a type of Double, so the comparison to -1 should be fine.  You may have already understood this as your question was in fact only in regards to the 1st 'If' statement.
