Hi Catalin,

after I try myself please change procedure of Class1 to :
Public WithEvents Appl As Application
Public bflag As Boolean
Private Sub Appl_WorkbookOpen(ByVal Wb As Workbook)
If Wb.Name = "X.xls" Then
For r = 1 To Windows.Count
If InStr(1, Windows(r).Caption, "Y.xls") 0 Then
bflag = True
Exit For
Else: bflag = False
End If
Next r
If bflag Then
MsgBox "Workbook Y.xls is currently opened !"
Else
MsgBox "You should open Workbook Y.xls first !"
End If
End If
End Sub

Hi Catalin Tri this:
in your Class module named Class1 :
Public WithEvents Appl As Application
Public bflag As Boolean
Private Sub Appl_WorkbookOpen(ByVal Wb As Workbook)
If Wb.Name = "X.xls" Then
For r = 1 To Windows.Count
If InStr(1, Windows(r).Caption, "Y.xls") 0 Then
bflag = True
Exit For
Else: bflag = False
End If
Next r
End If
If bflag Then
MsgBox "Workbook Y.xls is currently opened !"
Else
MsgBox "You should open Workbook Y.xls first !"
End If
End Sub

In your standard module :

Dim Apl As New Class1

Sub OpenFileX()
Set Apl.Appl = Application
filetoopen = Application.GetOpenFilename("Text Files (*.xls),
*.xls")
If filetoopen < False Then
Workbooks.Open filetoopen
If InStr(1, filetoopen, "X.xls") < 0 Then
If Apl.bflag = False Then ActiveWorkbook.Close False
End If
End If
Apl.bflag = False
Debug.Print InStr(1, filetoopen, "X.xls")
End Sub

Then Call openxfile procedure...
Note that the Workbook name is case sensitives

Thanks,,
halim

maybe you could adapt something like this


Sub test()
On Error GoTo err
Workbooks("Y").Activate
GoTo cont:
err:
MsgBox "workbook Y not open"
Exit Sub
cont:
MsgBox "workbook y is open"
End Sub

Hi to all and each one.

I'm looking to make a macro in VBA for the purposed posted below:

When I open the workbook "X", the macro should check if the workbook
"Y" is opened already. If not, either a message box should appear or
the workbook "Y" should be open.

Thanks in advance,
Catalin
