I'm developing an app in VS.net using VC++. I've created a dialog derived
from CDialog with a list box using CComboBox. I created a control variable
for the CComboBox called m_parentGroupList. The comboBox is the "Drop
List"
type which has a static edit box. I wish to blank out the edit box when
the
user makes a selection elsewhere in the dialog. The following code should
work but it doesn't.
CComboBox m_parentGroupList;
m_parentGroupList.SetCurSel(-1);
The contents of the edit box remains unchanged.
Are you calling
UpdateData(FALSE);
after doing it?
If he is, he should stop. :) If he's using DDX on that control, by using
SetCurSel he's created an inconsistency between the control's contents and
the associated member variable. In addition, UpdateData(false) will
transfer all the other member variables to the controls, overwriting any
changes that have been made since the last UpdateData(false).
