Retrieving desktop icon positions...

Greets all,

I'm trying to retrieve the positions of all the icons on the desktop in 95 using VC++.  
Any idea how to go about it?  

I've already tried grabbing the SysListView32 window and using the ListView_GetItemPosition
macro to attempt this, but it crashes Explorer every time I try.  The amusing/annoying thing is, I
CAN do a ListView_GetSelectedCount call using the same hwnd and get a valid answer.  Most
of the other ListView_* macros crash explorer as well, with some notable exceptions.  Is this
information in the registry somewhere?  Any hints or other possible directions to try would be
appreciated.

The problem stems from your assumption that the new common controls work similarly to the standard controls, they don't. The standard controls have code to copy data from one process to another. So when you send a control the WM_GETTEXT message, Windows has code to copy the text from the address space of the control into your address space. However, this code does not apply to the new common controls. So you cannot get to any of its API from another process.

That means the only way you can get to that information is if you were in the same process space of that window. This means you will have to create a DLL and insert into the process. You can do this fairly easily with a system hook. Then you will need to provide some interprocess communication with that DLL. You can subclass the desktop's window, provide a registered window message to communicate back and forth to get to the data.
