Abbat,
I don't know if you got my reply to the list. I'd go like this instead
(this is code to add to the form(s) you want to check):
* Private $bActive As Boolean = False** 'This private form
variable will hold the form's state
** Public Property Read IsActive As Boolean 'This property will
return the private variable value**
** Private Function IsActive_Read() As Boolean 'The function
declaration for reading the property**
** Return ***$bActive * ' the current form
state is returned**
** End**
**
Public Sub Form_Activate() 'This sub will change the
**private variable value to Active.
** **$bActive**** = True** ' flag the
state as Active.
** End**
**
Public Sub Form_Deactivate()** 'This sub will change
the **private variable value to Inactive.
** **$bActive**= False** ' flag the state
as Inactive.**
** End*
This works as follows: When you initially instance the form, the private
variable *$bActive* is set to FALSE.
When the form is activated, the *Form_Activate* event triggers and sets
the private variable *$bActive* as TRUE; when the form is deactivated,
the *Form_Deactivate* event triggers and sets the *$bActive* variable to
FALSE.
At any time, code external to the form can check the new form property
*IsActive* to find out if the form is active or not. This new property
will return the value TRUE or FALSE that has been set to the
*$bActive*** variable.
External code can check the new *IsActive* form property as follows:
* Dim myForm As New frmWithProperty 'frmWithProperty is a form with
the above new property code included
[... code ...]
** If myForm.IsActive Then
[... code for when the form is active...]
Else
** [... code for when the form is not active...]
Endif
[... even more code ...]*
The property can be added the same way to a single, some, or all forms
in the project.
Regards,
zxMarce.
