Hi !

 

I'm new to Shell Programming in C++, but I've some things to do with it.

I need to know the position of each item on the Windows desktop (current and all users) in order to be able to hide or show them like I want.

 

I've find how to enumerate objects on the Desktop (with a SHGetDesktopFolder and EnumObjects), but I don't know what to do after that.

I'm able to use SHGetFileInfo and SHGetDataFromIDList on the objects, but I can't do what I want :

• save icons (shortcuts, files, directories...) position
  
• hide / show some icons

Thanks for answers or ideas

I'm not too clear on your goals here, but you could QI on the IShellFolder to get IFolderView/IShellView which provide some of the functionality you describe.

Hi,

In fact, I want to modify and save the desktop Uset Interface. I'd like to be able to change icons' position, show/hide desktop items....

With SHGetDesktopFolder and EnumObjects, I can know what is on the desktop (visible or not) , like "My Computer" special folder, shortcuts, and other files on the desktop.

I want to retrieve/set the position of the icon corresponding to each enumerated object on the desktop view.

I've tried with the standard Win32 API way, by sending messages on the ListView corresponding to the desktop, but I could only Set an item position : I couldn't retrieve it.

I've read that it could work if I hook explorer.exe, but I don't see how to do that correctly.

 

I've tried to query a IFolderView Interface from the  SHGetDesktopFolder return, but it returns that IFolderView isn't supported.

 

Thanks for answer

Ok, this time I can set and retrieve Items position on the desktop !

I'm using the Win32 API, with SendMessage and a part of memory allocated in explorer.exe space with VirtualAllocEx.

Tell me if you're interested in the source code.

In brief I use the following functions : OpenProcess( explorer.exe ), VirtualAllocEx( hProcess ) / VirtualFreeEx, SendMessage(...), and ReadProcessMemory.

That will work for some circumstances, but I would strongly suggest getting the IFolderView to perform these actions.

 I wasn't clear earlier.  You should call GetUIObjectOf for the IShellView of the namespace, and then QI for the IFolderView interface.

Hi,

 I've made some tries with GetUIObjectOf, but I always get a "Not Implemented Yet" error.

For the moment, I keep on the Win32 way, but I think it won't work if the user is not an administrator...

 

If you have a sample code or a tutorial on GetUIObjectOf using in this case, could you send me the link to it ? ;)

 Thanks for help.
