How to access a SysListView32 control
  I write a script to create a SysListView32 control using nsDialogs, but it could only show a box. I want to insert columns and items into it, but after read the Messages of SysListView32 control at MSDN, I know that I must use API to access this control as some of the messages need "the pointer to an LVCOLUMN structure that contains the attributes of the new column".

I don't know how to use System plug-in to access it. I hope that nsDialogs provide more controls support, such as msctls_trackbar32, SysListView32, SysTreeView32 etc. in future.

until somebody abstracts the System plugin calls to manipulate these, you might be easier off with either http://nsis.sourceforge.net/EmbeddedLists_plug-in or http://nsis.sourceforge.net/InstallOption****plug-in

Hey, a person (username gfm688) in Dreams8.com write it to access the ListView control, and I made a demo using it:
