limiting the size of a CDialog

[nss]

I have a Cdialog with a CListCtrl in it that sizes along with the CDialog(MoveWindow). Theres text in the list, plus scrollbars. Whne the user lengthens the CDialog, the scrollbars eventaully vanish. AT this point I want the window to not be able to lengthen any further. How do I find out when the scrollbars have disappeared. I didnt see anything like BOOL ScrollBARsExist() or something like it in MSDN...maybe I need to get the height of the text in the cListctrl but how do I figure out that? Also theres no OnGEtMinMAxInfo for a CDialog...so what tells it to have a max limit?

override ::OnSizing(...) (don't forget to add the ON_WM_SIZING() handler in your message map).

Thanks! Any hints about detecting the vanishing of the clistctrl scrollbars?

compare GetScrollPos() and GetScrollLimit().

WM_GETMINMAXINFO certainly works for dialogs, although it might not appear in the ClassWizard so you'll need to add the message map entries yourself. --Mike-- The Internet is a place where absolutely nothing happens.   -- Strong Bad 1ClickPicGrabber - Grab & organize pictures from your favorite web pages, with 1 click!
