protection fault on VB Menu

I have a form wich contain menu with the following items:

File
Open
Save

I also have a timer that call the property mnuFile.Visible = False

The problem is that if I press the File
and then place the mouse on the Open/Save sub menus, I have a "Protection Fault" the minute the timer call it's property.

How do I solve it?

I couldn't reproduce your problem; in fact when I was on the Open/Save menus, and the timer did the File menu unvisible, the submenu remained visible until i clicked it, but not Protection Fault. There must be something else.

ET: more input, more input

I couldnt reproduce it either

actually i found where i could get an error...if i had the menu open and then when file disappeared, if I tried to move the mouse while file was missing it would crash the program.

Hi
Sorry, if I don't understand question, but what's about:
Private Sub mnuFile_Click ()
Timer1.Enabled = False
End Sub

Cheers

I was able to reproduce the Fault in VB5. By calling PopupMenu before hiding the menu stops the crash:

Option Explicit

Private Sub Form_Load()
Timer1.Enabled = False
Timer1.Interval = 1000
End Sub

Private Sub mnuFile_Click()
Timer1.Enabled = True
End Sub

Private Sub Timer1_Timer()
PopupMenu mnuFile
mnuFile.Visible = False
Timer1.Enabled = False
End Sub

Can you post the code you are using?
It is unusual to hide a menu while it is opened, if in fact this is what you are doing.

Without knowing more about what you are trying to do, everyone is speculating.

Perhaps you noticed the menu popup all the time because you did not disable the timer once the menu was hidden.

Private Sub Timer1_Timer()
PopupMenu mnuFile
mnuFile.Visible = False
'Disable timer
Timer1.Enabled = False
End Sub

Ok... let us be more specific.

How can I refresh the menu with API call

I think this will close all the open sub
menus.

i tried the popup menu option that Erick posted and it closed the submenus for me...only thing to change is to allow for the File menu option to become visible again

I noticed you have a duplicate question open regarding MDI menus. If your menu appears on the MDIMain form, you have to cancel that dropdown by calling:

Call SendMessage(MDIForm1.hwnd, WM_CANCELMODE, 0, 0)
