Hi, this is great piece of code.(exactly what I have been looking for) That being said I’m having some trouble implementing it into one of my projects. I have a form with a Sstab. On the tab I have a combo box and an MsFlexgrid.

I’m getting an error in the module when ever I use Hook Controls to be ignored: Call WheelHook(Combo1.hWnd) ( if I don’t hook the Combo1 then I don’t get the error. But then the msflexgrid has to have focus for the mouse scroll to work)

I get an Object Variable or with block variable not set Error. And VB highlights this line in the module: GetForm(GetParent(Lwnd)).MouseWheel MouseKeys, Rotation, Xpos, Ypos (I’m not familiar at all with API calls so I’m at a loss)

I get this error when I have used the mouse scroll 1st over the combo box and then use the mouse scroll over the form or over the flexgrid.

Any help would be greatly appreciated.( Just being able to mouse scroll all the controls is great, but you spoiled me with sample using the mouse over)
