Hello, I want to save docking position of toolbars in a MDI application
and
reterive it at begining of program.
I used SavebarState and LoadBarState but it dose not work when I use
LoadBarState before DockControlBar it gives an assertion failure then
crashes due to bad pointer.

CMainFrame::OnCreate(...)
{
...
//This code crashes
EnableDocking(CBRS_ALIGN_TOP);
m_ToolBar1.EnableDocking(CBRS_ALIGN_ANY);
m_ToolBar2.EnableDocking(CBRS_ALIGN_ANY);
m_ToolBar3.EnableDocking(CBRS_ALIGN_ANY);
LoadBarState(_T("Main ToolBar Docking Position"));
DockControlBar(m_ToolBar1);
DockControlBar(m_ToolBar2);
DockControlBar(m_ToolBar3);
}

when I put LoadBarState after DockControlBar it dose not crashes or give
assertion failure but position of toolbars are not the position when
prgram
has been closed.

CMainFrame::OnCreate(...)
{
...
//This code dose not crash but it dose not save position of toolbars
EnableDocking(CBRS_ALIGN_TOP);
m_ToolBar1.EnableDocking(CBRS_ALIGN_ANY);
m_ToolBar2.EnableDocking(CBRS_ALIGN_ANY);
m_ToolBar3.EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(m_ToolBar1);
DockControlBar(m_ToolBar2);
DockControlBar(m_ToolBar3);
LoadBarState(_T("Main ToolBar Docking Position"));//<<
}

toolbar position is saved in OnClose

OnClose()
{
SaveBarState(_T("Main ToolBar Docking Position"));

}

can someone figure out what's the problem, thanks.

I call SaveBarState() in OnDestroy(), not OnClose(). I'm not sure this
makes a difference.

Check the registry to make sure the barstate is saved. It's stored in
HKCU\Software\Company\Product, where "Company" and "Product" are affected by
CWinApp::SetRegistryKey() that you call in your CWinApp::InitInstance().
See that this key contains items for "Main Toolbar Docking Position".

Good luck,
David
