Multiple forms

I have 3 forms in my project.
Form 1 is the main form and gets displayed with application starts. It has a Menu Item to show form2. Form2 has a command button to show form3.  Whenever a form is shown, I do not want any other
form shown.

On form3 there is a text box that will update a list box on form2.

This could be generalized for any number of forms.

How can I do this?

If I understand correctly you can use the form.hide method to hide the form when the other is loaded.  The form is still loaded in memory, but not visible.

Hope this helps

To update something on Form2 from Form3, simply reference the object explicitly:

' code in form3:
Form2.Text1.Text = "I added this from Form3"

To show Form2 from Form1:

' code in form1:
private sub Command1_Click()
  Form2.Show ' vbModal (optional)
end sub

' code in form2:
private sub Command1_Click()
  Form3.Show ' vbModal
end sub

Sorry...

'from form1:
private sub Menu1_Click()
  me.hide
  Form2.Show
end sub

'from form2:
private sub Form_Unload()
  Form1.Show
end sub

Private sub Command1_Click()
  me.hide
  Form3.Show
end sub

' from form3:
private sub Form_Unload()
  Form2.Show
end sub

private sub Text1_LostFocus()
  Form2.List1.AddItem Text1.Text
end sub

I changed the menu item to a command button and I still get the same results.

Are you sure from1 is not hiding under form2?

Are you sure you did not put Form1.show in the Form_Load event of form 2?  It belongs in the Form_Unload event of Form2

This would cause form1 to remain visible.

Post your code from form 1's menu and we'll investigate.

If you want, you can be explicit by replaceing "me" with "form1":

private sub Menu1_Click()
 Form1.hide
 Form2.Show
end sub

I think it had something to do with the Form_Unload routine.
I did not have one in the early test application.

If you want to examine this more... I will try to reconstruct the sample that did not work.


Thanks again for your comments and help.
