Dear All, You're my last hope <g> I have the following situation. In Init event of grid I instantiate the Multiline Tooltip control (taken from Paul Vlad Tatave, many thanks!) as: =thisform.Addobject([cntMLTooltip],[cls_MLTooltip]) Basically,this control is container itself and consist from a shape, label and the timer that is disabled by default. The Interval property is 400 ms Also, I have in Header class MouseMove event the following code: thisform.cntMLTooltip.Timer1.Enabled = .t. And the problem is that VFP gives me an error to this line: No parameter statement found I checked everything but still have the error. There are no method with parameter. Can anybody give me an advice about this issue? I'm going to crazy ;(
