How can I completely close a specific workbook without closing other open workbooks?

Hi again guys!
I hope you can help me this time too.

I have a workbook where the user have to write a correct user & password (I made this using a form in VBA) before entering the workplace. But when the user open this workbook, it automatically close all the workbooks open before.

So, how I can do for open my workbook wich has an access form without closing or hiding other workbooks?

Note: Seems like the other workbooks don't close, but hide until the user put the correct data (user & password).

it sounds to me that whoever wrote the code you are running is shutting down the rest of the workbooks that are open. is that the case? can you post the code that you are running that is causing the problem? that would help out greatly.

Hi, vba_php I send you the code:

Private Sub Workbook_Activate()
Application.ExecuteExcel4Macro "Show.ToolBar(""Ribbon"",False)"
End Sub

Private Sub workbook_open()
Application.Visible = False
Application.OnKey "^p", ""
Application.OnKey "^x", ""
uf_login.Show
ActiveWindow.DisplayHeadings = False
End Sub
