[RESOLVED] Combo box visible property

[Urgentbody]

            If MATCell2 > 0 Then
                Combo2.Visible = True

                If Combo2.Visible = True Then
                I = I + 1
                End If
            End If

In design time Combo2.visible has been set to False

When MATCells > 0 is true during run time Combobox2 is visible.

Why the statement next

If Combo2.Visible = True Then

is not true ?

Object (including control) properties are not always simple values.

Assigning to them might do a number of things to cause something to happen, i.e. become visible. For that to take effect the message loop needs to gain control again to process and dispatch messages to message handlers.

Testing them might interrogate the actual status. If the messages have not been processed yet then the status will not have changed.


All of the code you can write in VB6 (with rare exceptions) is part of an event handler dispatched by the message loop. Until your event handler returns to its caller the message loop doesn't get control. The DoEvents() function works by making one pass through the message queue processing logic within the message loop (along with lots of other things) when called. Inserting such a call may or may not result in the updated status being reported by interrogating the property.
