auto close msgbox

I am opening a file with a macro and the file I am opening has a msgbox that opens right a way. I would like to close it so that my macro process can continue.
Can this be done?

<Sub open_File_Button()

SaveLocation (False)
     
    On Error Resume Next
    Workbooks(fname).Activate
     
     'If Excel cannot activate the book, then it's not open, which will
     '  in turn create an error not of the value 0 (no error)
     
    If Err = 0 Then
        'Exit Sub        'Exit macro if no error

SaveLocation (True)
        
    End If
     
    Err.Clear 'Clear erroneous errors
    Workbooks.Open fpath & fname

UserForm_File_Is_Open.Show
     
End Sub

I have tried something like that, but it did not work
Code I used was
Application.DisplayAlerts = False
Application.DisplayAlerts = True
Is this the same thing?

the message box was made with a form and is displayed instinly when you open the file and it states the General Information about this file for those who refference it's data. like my selef.

This is the code that displays the message, but I can't change any thing in that file.
and This code is located in the folder “Microsoft excel object” and named “ThisWorkbook”

Private Sub Workbook_Open()
    'this activates the General Instructions Form when the workbook is opened
    
    ActiveWindow.ScrollWorkbookTabs Position:=xlFirst
        Sheets("Master List").Select
        frmGeneralInformation.Show
End Sub
