Stops the timer that hides displayed ToolTips.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The ToolTip class has an internal timer that it uses to set the display duration for ToolTips. The duration associated with this timer is set through the AutoPopDelay property. The method will stop this internal timer, causing any displayed ToolTip to be shown modally until the Hide method is called, or the parent form is minimized, hidden, or closed.
