由于上篇C#操作QQ的TreeView控件以及詳細講解過如何操作其他進程的控件的流程,所以關于如何操作我就不在啰嗦了

主要實現流程如下

1), 獲取列數

?? 獲取列數需先獲取列的索引指針

columnIndex = WinAPIHelper.SendMessage(lvHwnd, (int)WinAPIHelper.LVM.GETHEADER, 0, 0);

?? 利用列索引指針去獲取列數量

columnCount = WinAPIHelper.SendMessage(new IntPtr(columnIndex), (int)WinAPIHelper.HDM.HDM_GETITEMCOUNT, 0, 0);

2), 獲取行數

rowCount = WinAPIHelper.SendMessage(lvHwnd, (int)WinAPIHelper.LVM.GETITEMCOUNT, 0, 0);

3), 遍歷所有cell,使用LVITEM獲取需要的數據

iRet = WinAPIHelper.SendMessage(lvHwnd, (int)WinAPIHelper.LVM.GETITEMW, j, pItemMemory);

像這些沒有技術難點的東西我會講的少一點,大家可以查MSDN,需要我的APIHelper類,請留言

這篇代碼實現比較濫,大家可以自己拿去改
