Hi,

I have a check button in a CPropertyPage. It needs to change it's state based on data from the item selected from a list box. I've done similar things in other places and haven't had any problems using:

if( someBool )
m_cButton.SetCheck(BST_CHECKED);
else
m_cButton.SetCheck(BST_UNCHECKED);

in the event handler for list selection change, where m_cButton is bound in DoDataExchange.

For some reason however when I do this here it always unchecks the button, no matter the value passed to SetCheck, which I've checked in the debugger. I have also tried CheckDlgButton and (CButton*)GetDlgItem(IDC_CHECKID)->SetCheck but get the same result.

Does anyone have any idea what could be causing this?

Thanks for any help.
