|
|
// History:
|
|
// 10 May 1998 Uses GVN_ notifications instead of LVN_,
|
|
// Sends notification messages to the parent,
|
|
// instead of the parent's parent.
|
|
// 15 May 1998 There was a problem when editing with the in-place editor,
|
|
// there arises a general protection fault in user.exe, with a
|
|
// few qualifications:
|
|
// (1) This only happens with owner-drawn buttons;
|
|
// (2) This only happens in Win95
|
|
// (3) This only happens if the handler for the button does not
|
|
// create a new window (even an AfxMessageBox will avoid the
|
|
// crash)
|
|
// (4) This will not happen if Spy++ is running.
|
|
// PreTranslateMessage was added to route messages correctly.
|
|
// (Matt Weagle found and fixed this problem)
|
|
// 26 Jul 1998 Removed the ES_MULTILINE style - that fixed a few probs!
|
|
// 6 Aug 1998 Added nID to the constructor param list
|
|
// 6 Sep 1998 Space no longer clears selection when starting edit (Franco Bez)
|
|
// 10 Apr 1999 Enter, Tab and Esc key prob fixed (Koay Kah Hoe)
|
|
// Workaround for bizzare "shrinking window" problem in CE
|
|
//
