Prevent multiple form instances

[NachoShaw]

Hi

Not been here for a while or done any coding for about 12 months, just picking up an old project i wanted to get finished. What is the best method to prevent multiple forms being instantiated when the button to load the form is clicked? I am using the following

in AddinGlobal Class

Friend Shared FormOpen As Boolean = False


in the Form Load Event

AddinGlobal.FormOpen = True


in the Form Close event

AddinGlobal.FormOpen = False


in the method to open the form


If Not AddinGlobal.FormOpen Then
dim f as New frmMain
f.Show(New InventorWin())
End If


Im sure there must a more official way of managing this, i would like to do this properly instead of it just working. One thing that might get commented on is the Friend Shared access level. It seems that if i dont share it, i cant access it from anywhere..


Anyways, any help / advice is always appreciated


Thanks


Nacho
