VB Migration Partner supports this property, so that the VB.NET code always compiles correctly. The NegotiatePosition property isn’t supported by. VB Migration Partner is aware of this difference and fires the Click event at the right time even for dropdown menus. If you need to handle the Click event of dropdown menus you should use the DropDownOpened event instead. For this reason, event handlers generated by the Upgrade Wizard might be executed at the wrong time and cause runtime errors or bogus results. NET fires the Click event before the dropdown menus becomes visible. VB.NET menus support the Click event however, in VB6 the Click event of dropdown menu fires immediately after the menu becomes visible, whereas. VB Migration Partner can correctly handle these assignments and correctly transforms a menu element into a separator (or vice versa), depending on the value being assigned to the Caption property. If you assign a “-“ (dash) character to the Caption property, you actually transform the menu element into a menu separator under VB6, even at runtime. NET, but there is an important difference. The Caption property maps to the Text property under. VB Migration Partner handles this important difference internally and generates VB.NET code that behaves like the original VB6 code in virtually all cases. (A VB6 separator is a plain menu object whose Caption property is set to the “-“ character.) Separator bars are translated as ToolStripSeparator objects.Drop-down menus are translated as ToolStripMenuItem objects.Top-level menus are translated as MenuStrip objects there is only one MenuStrip object in each form, whose child controls are drop-down menus.VB.NET uses three different objects to render the VB6 Menu object.
