LoadBarState/SaveBarState

[Chris Weiler]

Hi!

I store (re-) the states of my dockable toolbars by means of
SaveBarState (load-) in OnClose (OnCreate).

With 2 toolbars there was no problem. But after adding a 3rd one
restored positions were wrong(ID'S of toolbars are different, VC++6.0)!

I think the registry entries which have been saved by SaveBarState are
wrong because e.g. BarID=53369 although it should be 109.

Did anyone else experience this problem?

Thanks in advance!

Insert this function, to ignore the invalid serialized toolbardockstate.

PS. This function helps to avoid GPF during CFrameWnd::SetDockState execution:
when one of the previously saved toolbars is not created, SetDockState fails.

BOOL CMainFrame::IsDockStateValid (const CDockState& state)
{
for (int i = 0; i < state.m_arrBarInfo.GetSize (); i ++)
{
CControlBarInfo* pInfo = (CControlBarInfo*) state.m_arrBarInfo [i];
ASSERT (pInfo != NULL);

if (!pInfo->m_bFloating)
{
//---------------------------------------
// Find the control bar with the same ID:
//---------------------------------------
if (GetControlBar (pInfo->m_nBarID) == NULL)
{
TRACE (_T("IsDockStateValid ControlBar %x(%d) is not valid!\n"),
pInfo->m_nBarID,pInfo->m_nBarID);
return FALSE;
}
}
}
return TRUE; //all states are valid
}

CMainFrame::OnCreate(...)
{
//Create toolbar's
...
CDockState state;
state.LoadState("Toolbar");
if(IsDockStateValid(state))
SetDockState(state);

}
