Hi Vlad! Thank you for answer that I've found right after sending my message ;) Thank God, I'm still not crazy ;))) >The error in MouseMove is because this method must have a LPARAMETERS line. >Just open a MouseMove event that has never been modified and you'll see >that FoxPro puts there a LPARAMETERS line. You can also find it in the help >Why do you want to enable this control in the MouseMove event. Do you wanna >use it just for the grid? I do it because firing the timer in grid is very unconvenient and causes error under some conditions. I've modified your control to enable only in Header of column not when the mouse over Column or other object. BTW, I would like to suggest the little addition to your control. It could be just cool if your control can check that the property icToolTipText (or something like) is exist in object that is under mouse and can use this property instead of TooltipText property. It is because of limitation of Tooltip length. BTW again, you made just cool control, thank! >>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.
