How to capture the Event or WM_messages when the HeadColumns of the ListView resized

[michi]

Hi,

I want to capture the event when user resize the headercolumn of a listview, and then store the column length.

I cannot find a related Event of ListView, I am wondering if I should use windows Hook. If so, what the WM_messages I can use?

Thanks.

There is a subclassing control called EventCtl.dll at http://www.merrioncomputing.com/Download/index.htm which is a good start. I can even supply source code (given some notice).

The message you are looking for is probably WM_NOTIFY although there are several ListView specific messages registered ... prefix LVM_ which might be appropriate.

HTH,

Thanks for your kindly help.

I have downloaded EventCtl.dll, but I still cannot find with one I can use for the ListView ColumnHeader resizing event.

To use WM_NOTIFY, I need to know the message of the NMHDR structure (which contains information about a notification message). Unfortinatly, I was sticked here.

I tried to use ListView_MouseDown event, but it can not be trigger when I drag the ColumnHeader,except when I clicked other place in the ListView.

Thanks again.
