Copy data from closed workbook based on variable user defined path - vba

Question

I have exhausted my search capabilities looking for a solution to this. Here is an outline of what I would like to do:
User opens macro-enabled Excel file
Immediate prompt displays for user to enter or select file path of desired workbooks. They will need to select two files, and the file names may not be consistent
After entering the file locations, the first worksheet from the first file selection will be copied to the first worksheet of the macro-enabled workbook, and the first worksheet of the second file selection will be copied to the second worksheet of the macro-enabled workbook.
I've come across some references to ADO, but I am really not familiar with that yet.
Edit: I have found a code to import data from a closed file. I will need to tweak the range to return the variable results.
Private Function GetValue(path, file, sheet, ref)
path = "C:\Users\crathbun\Desktop"
file = "test.xlsx"
sheet = "Sheet1"
ref = "A1:R30"
' Retrieves a value from a closed workbook
Dim arg As String
' Make sure the file exists
If Right(path, 1) <> "\" Then path = path & "\"
If Dir(path & file) = "" Then
GetValue = "File Not Found"
Exit Function
End If
' Create the argument
arg = "'" & path & "[" & file & "]" & sheet & "'!" & _
Range(ref).Range("A1").Address(, , xlR1C1)
' Execute an XLM macro
GetValue = ExecuteExcel4Macro(arg)
End Function
Sub TestGetValue()
path = "C:\Users\crathbun\Desktop"
file = "test"
sheet = "Sheet1"
Application.ScreenUpdating = False
For r = 1 To 30
For C = 1 To 18
a = Cells(r, C).Address
Cells(r, C) = GetValue(path, file, sheet, a)
Next C
Next r
Application.ScreenUpdating = True
End Sub
Now, I need a command button or userform that will immediately prompt the user to define a file path, and import the data from that file.

I don't mind if the files are opened during process. I just didn't want the user to have to open the files individually. I just need them to be able to select or navigate to the desired files
Here is a basic code. This code asks user to select two files and then imports the relevant sheet into the current workbook. I have given two options. Take your pick :)
TRIED AND TESTED
OPTION 1 (Import the Sheets directly instead of copying into sheet1 and 2)
Option Explicit
Sub Sample()
Dim wb1 As Workbook, wb2 As Workbook
Dim Ret1, Ret2
Set wb1 = ActiveWorkbook
'~~> Get the first File
Ret1 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select first file")
If Ret1 = False Then Exit Sub
'~~> Get the 2nd File
Ret2 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select Second file")
If Ret2 = False Then Exit Sub
Set wb2 = Workbooks.Open(Ret1)
wb2.Sheets(1).Copy Before:=wb1.Sheets(1)
ActiveSheet.Name = "Blah Blah 1"
wb2.Close SaveChanges:=False
Set wb2 = Workbooks.Open(Ret2)
wb2.Sheets(1).Copy After:=wb1.Sheets(1)
ActiveSheet.Name = "Blah Blah 2"
wb2.Close SaveChanges:=False
Set wb2 = Nothing
Set wb1 = Nothing
End Sub
OPTION 2 (Import the Sheets contents into sheet1 and 2)
Option Explicit
Sub Sample()
Dim wb1 As Workbook, wb2 As Workbook
Dim Ret1, Ret2
Set wb1 = ActiveWorkbook
'~~> Get the first File
Ret1 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select first file")
If Ret1 = False Then Exit Sub
'~~> Get the 2nd File
Ret2 = Application.GetOpenFilename("Excel Files (*.xls*), *.xls*", _
, "Please select Second file")
If Ret2 = False Then Exit Sub
Set wb2 = Workbooks.Open(Ret1)
wb2.Sheets(1).Cells.Copy wb1.Sheets(1).Cells
wb2.Close SaveChanges:=False
Set wb2 = Workbooks.Open(Ret2)
wb2.Sheets(1).Cells.Copy wb1.Sheets(2).Cells
wb2.Close SaveChanges:=False
Set wb2 = Nothing
Set wb1 = Nothing
End Sub

The function below reads data from a closed Excel file and returns the result in an array. It loses formatting, formulas etc. You might want to call the isArrayEmpty function (at the bottom) in your main code to test that the function returned something.
Public Function getDataFromClosedExcelFile(parExcelFileName As String, parSheetName As String) As Variant
'see http://www.ozgrid.com/forum/showthread.php?t=19559
'returns an array (1 to nRows, 1 to nCols) which should be tested with isArrayEmpty in the calling function
Dim locConnection As New ADODB.Connection
Dim locRst As New ADODB.Recordset
Dim locConnectionString As String
Dim locQuery As String
Dim locCols As Variant
Dim locResult As Variant
Dim i As Long
Dim j As Long
On Error GoTo error_handler
locConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" _
& "Data Source=" & parExcelFileName & ";" _
& "Extended Properties=""Excel 8.0;HDR=YES"";"
locQuery = "SELECT * FROM [" & parSheetName & "$]"
locConnection.Open ConnectionString:=locConnectionString
locRst.Open Source:=locQuery, ActiveConnection:=locConnection
If locRst.EOF Then 'Empty sheet or only one row

If locRst.Fields.Count = 1 And locRst.Fields(0).Name = "F1" Then Exit Function 'Empty sheet
ReDim locResult(1 To 1, 1 To locRst.Fields.Count) As Variant
For i = 1 To locRst.Fields.Count
locResult(1, i) = locRst.Fields(i - 1).Name

If locRst.Fields.Count = 1 And locRst.Fields(0).Name = "F1" And UBound(locCols, 2) = 0 And locCols(0, 0) = "" Then Exit Function 'Empty sheet
ReDim locResult(1 To UBound(locCols, 2) + 2, 1 To UBound(locCols, 1) + 1) As Variant
If locRst.Fields.Count <> UBound(locCols, 1) + 1 Then Exit Function 'Not supposed to happen

Exit Function
