Changing style of a subclassed CEdit

Posted on 2004-10-29

Last Modified: 2013-11-20
I'am using a subclassed CEdit in a CComboBox and have a CEdit derived class for that. For the edit control I want to set the ES_NOHIDESEL style.
Unfortunately PreCreateWindow() or OnCreate() are never called by a subclassed control and so I don't know, how to set the style. ModifyStyle() doesn't work with ES_NOHIDSEL.
I also would agree to another solution than subclassing for using an own edit control in a combobox.

Thanx for your help.

override the virtual function PreSubclassWindow and modify the style there (in your edit class).
The OnCreate and PreCreate have already been called by the time you perform the subclassing hence you never get them them in your class.

Hi amrit_82,
I know these article. It doesn't give an answer to my question.

Hi AndyAinscow,
to change it in PreSubclassWindows also was my idea, but I don't know how. There is no CREATESTRUCT parameter, that I can modify and ModifyStyle() doesn't work.

Excerpt from help

Edit Control Styles
To create an edit control using the CreateWindow or CreateWindowEx function, specify the EDIT class, appropriate window style constants, and a combination of the following edit control styles. After the control has been created, these styles cannot be modified, except as noted.

ES_NOHIDESEL is one that can't be changed after creation.

As I see it you have two possibilites.
1) Create the control with the ES_NOHIDESEL style.
2) Instead of subclassing, get the control styles, ID, position, visibility etc.  Delete edit control. Create your own to replace the one you deleted and set styles, content, visibility ...
