Ok, the file is here

Run form 'Demo'. Not all options on the demo work yet, but you'll get the idea.

Thanks




>Sounds complicated. :) Can't really say more without actually seeing it. Can you sent me a sample?

>>>>>Then it might be different. Is that the actual VFP listbox or some compound control that looks like listbox? If that is a listbox, then you have only one object under the mouse - the listbox itself. You might try to calculate how many rows are under the mouse in the mouse move process. If the mouse button is pressed, that might interfere with the normal listbox responce to the mouse.

>>>>>>>Hi Kevin,

>>>>>>>What exactly "the user drags the mouse over them" means?
>>>>>>>
>>>>>>>Say, the user dragged the mouse drawing S - shaped line. There are multiple controls on the form. Do you want only the controls the mouse went over directly to be selected?
>>>>>>>Or include any controls that are within the rectangle defined by the initial and final mouse positions?
>>>>>>>
>>>>>>>For the first case you could use MouseMove() event, "probing" the underlying controls with SYS(1270), for example:
>>>>>>>

>>>>>>>loTarget = SYS(1270) && Get the object under the mouse
>>>>>>>cTarget = SYS(1272, loTarget) && get the object hierarchy for a specified object.
>>>>>>>

>>>>>>>
>>>>>>>For the second case you could deternine the initial and final mouse positions and then write a routine that will check what controls on the form are withing that rectangle. In both cases the list/array of "selected" controls can be created and somehow processed later.
>>>>>>>
>>>>>>>Both ways could be combined, depending on what you are going to achieve. Also, I assume you are dragging the mouse with Left or Right mouse button pressed.
