Are you using this code in OnInitDialog after calling the base class's
OnInitDialog?

Evening,

I am creating a status bar as follows:

c_StatusBar.Create(this);
c_StatusBar.ShowWindow(SW_SHOW);

and then proceding to set its panes.

CStatusBarCtrl& bar = c_StatusBar.GetStatusBarCtrl();
int align = 0;
int widths[] = {
    align+ 0, // status and time
    align+=40, // avatar
    align+=40, // bots
    align+=40, // tourists
    align+=40 };
const int parts_total = sizeof(widths) / sizeof(widths[0]);
bar.SetParts(parts_total, widths);
for (int i = 0; i < parts_total; i++)
    c_StatusBar.SetPaneStyle(i, SBPS_POPOUT);

SetPaneStyle however blows up with debug showing that it finds a null
pointer for the pane. - This code is all being executed on OnInitDialog
however doing it on other notifications (ie: buttons) fails also with the
same error.

Could anyone advise please?
