VFP 7.0 active middle scroll on mouse

[bettyfurr]

I have a user with a combobox that would like to use th scroll on the mouse to pick off her chose.

Are there any way to active this feature in VFP 7.0?

Thanks

You may find the MiddleClick, MouseDown, and MouseMove events helpful in your endeavour. The nButton parameter for mousedown and mousemove will be 4 if it is the middle mouse button.

Thank you for your help. Please give an example of what the
LPARAMETERS [nIndex,] nButton, nShift, nXCoord, nYCoord

I am having problems with the syntax.

Thank you again

Those are events that fire for the combobox control. You needn't send in the lparameters as VFP/Windows will handle this for you...you just need to check the results and then do whatever you want based on whether the user was using the middle mouse button.

LPARAMETERS nButton, nShift, nXCoord, nYCoord
if nButton = 4
 *!* Do something useful here
endif

The problem is that the middle scroll button is ignored. There is no movement of the mouse. I just want it to scroll the combobox items on the list.

Is this possible?
