>>When an item is dragged from a listbox OVER an node item within the treeview, I want that node to appear highlighted or selected. I have a tree with two levels (parent & children).
>>I looked at VFP 7 sample ...\samples\solution\tahoe\listdd, and started with their code under OLEdragOver, setup the drap icons, and etc..., and have been tinkering with it but I have not been able to get it to work correctly. The MSDN help has it that you can simply plug the X & Y parameters into HITTEST() and get the right node object but that didn't work. The sample multiplies and divides x & y but specific constants but that did not work. I looked through the properites of the sample to see if the constants had any rhyme or reason and noted one number equaled the .height of that treeview and the other to how .left it was times 10. I tried that with my treeview and it worked "a little" strangely enough but it was very inaccurate.

>15 is not a constant nor magic value. It comes from horizontal-vertical aspect values (generally 96 pixels per inch). One inch is 1440 twips (72 dpi and 1 point = 20 twips). 1440/96 = 15.
>Check UT magazine Jne 2001 issue with sample code. It has the dragover highlighting code almost same as VFP samples'

Does this mean that the value will change with screen resolution?
