So I have listview control with LVS_REPORT and LVS_NOSORTHEADER styles enabled , and I would like to prevent user from changing column header width,
so when user try to click and drag no action would occur...

One solutin I did try was to subclass WM_LBUTTONDOWN message and that worked , but this message does not register left mouse click in column header area Rolling Eyes

and I did try various LVN_ notification messages but without success...

so any help is appreciate ...
thx

IIRC list view uses Header Controls for the column header(s). You can get the handle of the header control and capture the WM_NOTIFY message for HDN_BEGINTRACK notifications.

@revolution
thank you very much,
HDN_TRACK message did it...

btw
I have to admit I never heared or used header controls before and as far as I can say listview pages in psdk do not mention them as one a lvs_report column header can be controled by,nvm learn something new every day,
thx again...

Preventing the user?! - not many users will use the program.
