Question

I have checked many places for the answer to this, and they recommend the way I have done it, but it doesn’t seem to work for me, so any help would be greatly appreciated.

I have a check box and I would like it to enable an edit box when it is check and disable it when unchecked.

The following code is what I have created:

void CMFCApplication1Dlg::OnBnClickedCheck1()
{
    UINT nCheck = CheckBox.GetState();
    if (nCheck == BST_CHECKED)
    {
        EditBox.EnableWindow(TRUE);
    }
    else if (nCheck == BST_UNCHECKED)
    {
        EditBox.EnableWindow(FALSE);
    }
    else
    {
        EditBox.EnableWindow(TRUE);
    }

nCheck is 520 when I run it in debug, so goes straight to the else option.

Many thanks

CButton’s GetState gets the current state of the dialog object. What you want to be using is CButton’s GetCheck.

Alternatively, you can, as indicated on MSDN, do a bitwise mask on the return value to get the current Check state – but GetCheck is right there, so you might as well use it.
