You have to find the desktop listview's handle like this:

var lv : dword;

lv := FindWindowEx(FindWindowEx(FindWindow('Progman', 'Program Manager'), 0, 'SHELLDLL_DefView', ''), 0, 'SysListView32', '');

Now you have to do

  SetWindowLong(lv, GWL_STYLE, GetWindowLong(lv, GWL_STYLE) and (not LVS_AUTOARRANGE));

The big problem is that SetWindowLong works only for windows that own to your own process. So this all doesn't work from your application. You have to put this in a dll, then you must manage to load your dll into the explorer's process somehow, then execute this code there. *QUITE* difficult...

Another possibility would be to use some APIs to open the context menu of the desktop and execute the appropriate menu item (difficult, too, but not THAT difficult). The main problem here is that you have to find the correct menu item. You can only look for a specific text which would be language dependent. VERY ugly... So the first suggestion would be much better - though more difficult, too.

Regards, Madshi.

Hi, Madshi:

Thanks for your help.

It seems I ask 2 question for same problem. Try to deal with another process with just a handle of it.

If you do not mind, could you please check the other question?
