So, you want to trigger an Excel function from Access, or run an Excel subroutine from Access?

To run a function, you can do something like this.

  Public Function FV(dblRate As Double, intNper As Integer, _ 
                  dblPmt As Double, dblPv As Double, _ 
                  intType As Integer) As Double
     Dim xl As Object
     Set xl = CreateObject("Excel.Application")
     FV = xl.WorksheetFunction.FV(dblRate, intNper, dblPmt, dblPv, intType)
     Set xl = Nothing
 End Function

enter image description here

To run an Excel subroutine from Access, you can do the following.

Sub RunExcelMacro()
Dim xl As Object
'Step 1:  Start Excel, then open the target workbook.
   Set xl = CreateObject("Excel.Application")
    xl.Workbooks.Open ("C:\Book1.xlsm")
'Step 2:  Make Excel visible
   xl.Visible = True
'Step 3:  Run the target macro
   xl.Run "MyMacro"
'Step 4:  Close and save the workbook, then close Excel
   xl.ActiveWorkbook.Close (True)
    xl.Quit
'Step 5:  Memory Clean up.
   Set xl = Nothing 
End Sub

You'll probably want to use Application.Run from Excel's object model. You pass it a string such as "QuickRDA.JavaCallBacks.GetQuickTab" for the macro name, where QuickRDA is the name of the Excel VBA project, JavaCallBacks is the name of the VBA module in that VBA project, and GetQuickTab is the name of the function in that VBA module.

In Access

Sub Connect()    
    Dim xlApp As Variant
    Set xlApp = GetObject(, "Excel.Application")
    'this will connect to an already open copy of excel, a bit easier for quick & dirty testing
    Let ans = xlApp.Application.Run("MyXLVBAProject.MyXLVBAModule.testme")
End Sub

In Excel

Public Function testme() As String
    Dim xlpath As String
    Dim concate As String
    Dim value as String
    xlpath = ActiveWorkbook.Path
    value = ActiveWorkbook.Name
    concate = xlpath & "\" & value     
    Let testme = concate
End Function

-or simply-

Public Function testme() As String
    Let testme = ActiveWorkbook.FullName
End Function

Remember that in Excel the function testme should be put in a module whose name is MyXLVBAModule, and that the project containing the module should be called MyXLVBAProject.
