Answer 1

You should add a precompile If statement to work with Win 32 and 64.

The code below will make this work in Windows 32 and 64 bit systems.

Option Explicit
#If Win64 Then
    Private Declare PtrSafe Function FindWindowA Lib "USER32" _
        (ByVal lpClassName As String, _
        ByVal lpWindowName As String) As Long
    
    Private Declare PtrSafe Function GetWindowLongA Lib "USER32" _
        (ByVal hWnd As Long, _
        ByVal nIndex As Long) As Long
    
    Private Declare PtrSafe Function SetWindowLongA Lib "USER32" _
        (ByVal hWnd As Long, _
        ByVal nIndex As Long, _
        ByVal dwNewLong As Long) As Long
#Else
    Private Declare Function FindWindowA Lib "USER32" _
        (ByVal lpClassName As String, _
        ByVal lpWindowName As String) As Long
    
    Private Declare Function GetWindowLongA Lib "USER32" _
        (ByVal hWnd As Long, _
        ByVal nIndex As Long) As Long
    
    Private Declare Function SetWindowLongA Lib "USER32" _
        (ByVal hWnd As Long, _
        ByVal nIndex As Long, _
        ByVal dwNewLong As Long) As Long
#End If
