I realize that _GUICtrlListView_HideColumn doesn't do anything but set the size to zero. However, when set to zero the user can still expand that column if they drag the header. Is it possible to disable the user from doing this? I've looked at WM_NOTIFY and a message called $LVN_GETDISPINFO shows up a bunch whenever the column is being resized, however this message seems to come in a lot anyways all the time.

Anybody have any ideas?

Here's some code almost exactly from the helpfile (I enabled the $LVN_GETDISPINFO):

#AutoIt3Wrapper_au3check_parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>

look at _GUICtrlHeader_Create example.

Change the Case $HDN_BEGINTRACK, $HDN_BEGINTRACKW to return true.

also you'll need _GUICtrlListView_GetHeader.

That looks like what I need, thanks.

However it means I'll have to rewrite the code for my listview to use no default headers and use _GUICtrlHeader_Create and then program the sorting and all that accordingly. Still, I like that headers also allow you to drag columns, I'll have to implement that too..

Shouldn't, if you use the second part that I said.
