CEditView setting styles in PreCreateWindow : losing other styles

[Franky Braem]

Hi,

When I'm changing the style to ES_READONLY in the PreCreateWindow method of my CEditView I loose the ES_MULTILINE style and some other styles.

My code is as follows :

BOOL CMyEditView::PreCreateWindow(CREATESTRUCT &cs)
{
cs.style |= ES_READONLY;
return CEditView::PreCreateWindow(cs);
}




Am I doing something wrong by using the | operator ?
