Sometimes my UserControl's Visible property does not get updated correctly. It happens at my app's boot time, in OnFontChanged, fired from inside InitializeComponent, probably because some other stuff has not been set up yet. I just can't find out what.
vScrollBar is a UserControl and is inside another UserControl. Apparently, this only happens when trying to set the value to true.
vScrollBar already has its handle created, as a watch on IsHandleCreated says it's true.

You can use the Visible property to hide a control on a form or report by including the property in a macro or event procedure that runs when the Current event occurs. For example, you can show or hide a congratulatory message next to a salesperson's monthly sales total in a sales report, depending on the sales total.
Although code in your control may still run while invisible, you will not be able to interact with the control through the user interface. If you want to create an invisible control that still responds to user input (for example, mouse clicks), you should create a transparent control.
Visible property is used to hide the object at run time. Width property sets the TextBox to the desired width at design time.
Reading the Visible property gives you the actual visibility state of the control, not the 'intended' state. Which will always be false in the InitializeComponent() method, the form or control isn't visible yet until after the Load event runs. It will also be false if the container control isn't visible.
