CViewState::InitializeColumns函数分析之_hdsaColumnStates的结构

    // Set up saved column state only if the saved state     // contains information other than "nothing".

    if (_hdsaColumnStates)     {         UINT cStates = DSA_GetItemCount(_hdsaColumnStates);         if (cStates > 0)         {             // 99/02/05 vtan: If there is a saved column state then             // clear all the column "on" states to "off" and only             // display what columns are specified. Start at 1 so             // that name is always on.        把35项的选中标志置OFF

            for (iReal = 1; iReal < GetColumnCount(); iReal++)             {                 COL_INFO* pci = (COL_INFO*)DSA_GetItemPtr(_hdsaColumns, iReal);                 pci->csFlags &= ~SHCOLSTATE_ONBYDEFAULT;             }             //把_hdsaColumnStates的结构对应数组置ON，这里是0,1,2,3,6项的选中标志置ON             for (UINT i = 0; i < cStates; i++)             {                 DWORD dw;                 DSA_GetItem(_hdsaColumnStates, i, &dw);                 SetColumnState(dw, SHCOLSTATE_ONBYDEFAULT, SHCOLSTATE_ONBYDEFAULT);             }         }     }

    return S_OK; }
