其中LVCFMT_IMAGE表示可以在第一列加入图标。如果不要图标可以删去。
然后设置列宽：
for(j=0;j<3;j++)
m_ListCtrl.SetColumnWidth(j ,100);
以下为列表加入图标，如果不需要图标，可以跳过这一步。注意只在第一次加入，如果多次加入会出错！
先在头文件中加入声明：
CImageList m_ImageList;
这是必要的，如果在cpp的某个函数中加入由于生命期结束，CImageList自动释放，则效果是列表中看不到图标，只看到一个白方块。
下面生成CImageList，并将其绑定到CListCtrl中，这是CImageList中还没有图标，只是一个容器：
