How save checked status button state?

Hi,

I have stupid problem with command bar customization: If I check some button and I save command bar (SaveStateToXMLString method) when I reload it the checked button status was lost. I create tool bar by code the first time that my application run or if I can’t load xml file with last configuration. My application remembers correctly a new button added by user or moved but not the check state . I think I have an error when I create State Options, this is my setting:

    objStateOption.LoadSilent = True

    objStateOption.SaveOnlyCustomized = False   

    objStateOption.SaveOriginalControls = True

    objStateOption.SerializeDesignerControls = False

    objStateOption.SerializeControls = True

    objStateOption.SerializeImages = False

    objStateOption.SerializeLayout = True

    objStateOption.SerializeOptions = True

Any idea?

Regards,
