Fix or float component in active or all configurations using SOLIDWORKS API

This VBA example demonstrates a simple workaround for missing SOLIDWORKS API to fix or float the component in active configuration only. IAssemblyDoc::FixComponent only fixes the components in all configurations.

Create an example assembly with 2 configurations and 4 instances of the component, where first 2 instances are floating in both configurations, while last 2 instances are fixed in both configuration.

As the result of running this macro components will be changed to the following result:

#If VBA7 Then
     Private Declare PtrSafe Function SendMessage Lib "User32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
#Else
     Private Declare Function SendMessage Lib "User32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
#End If
