Getting the Win95 Desktop ListView Handle
Question:
How do I get a handle to the Windows 95 Desktop to access the
Desktop icons?
Answer:
The Windows 95 Desktop is overlayed with a ListView component.
You simply need to get a handle to the ListView. Example:
function GetDesktopListViewHandle: THandle;
var
S: String;
begin
Result := FindWindow('ProgMan', nil);
Result := GetWindow(Result, GW_CHILD);
Result := GetWindow(Result, GW_CHILD);
SetLength(S, 40);
GetClassName(Result, PChar(S), 39);
if PChar(S) <> 'SysListView32' then Result := 0;
end;
Once you have the handle, you can use the list view-related API
functions in the CommCtrl unit to manipulate the desktop. See
the LVM_xxxx messages in the Win32 online help.
For example the following line of code:
SendMessage(GetDesktopListViewHandle,LVM_ALIGN,LVA_ALIGNLEFT,0);
will align the desktop icons to the left side of the Windows 95 desktop.
