关于Listview控件显示图标问题?

[jhtzz]

我试过了我用ListView和ImageList关联,但是显示图标很慢而且显示得越多越站资源,但后我看了不少关于ListView显示图标的API后发现很多例程真的不占资源了，显示很快的，他们不用ImageList，全是API实现的，但我看不懂,
' LVM_GET/SETITEM lParam
Public Type LVITEM ' was LV_ITEM
mask As Long
iItem As Long
iSubItem As Long
state As Long
stateMask As Long
pszText As Long ' if String, must be pre-allocated
cchTextMax As Long
iImage As Long
lParam As Long
比如说这些，但我如果要独立做出来的话不知道怎么做了,我想请问各位帮忙能直解了当显示图标的方法呀
