Activate Excel Window Upon Export from Access

I want to make the Excel window the active window upon export from Access.
Wasnt sure what code to use and where to put it (Excel or Access) Below I
have included both the code for the export out of Access and the code that I
have in Excel. Any help would be appreciated. Right now after I hit the
export button the dialog box that allows the user to select a folder appears
in the background behind Access window.

Export button in Access

DoCmd.TransferSpreadsheet acExport, _
acSpreadsheetTypeExcel9, "qryGraphExportStep4Dept", _
"\\naeanrfkfs27\C163\Navsea_inhd_nswc03\C6\Shared\CompleteAndOnTime\qryGraphExportStep4.xlt", , "qryGraphExportStep4"
Application.FollowHyperlink
"\\naeanrfkfs27\C163\Navsea_inhd_nswc03\C6\Shared\CompleteAndOnTime\qryGraphExportStep4.xlt"
