To get information from other process you need to use inter-process communication.

This sample shows how to do this with listview. You can use this way to work with treeview.

Check this code.


int tvhi;
tvhi = 263290;
HWND tvh;
tvh = (HWND)tvhi;

HTREEITEM tvroot;
tvroot = (HTREEITEM)SendMessage(tvh,TVM_GETNEXTITEM,TVGN_ROOT,0);

if(tvroot==NULL)
MessageBox(hWnd,"err1","asdf",MB_OK);

TVITEMEX itemobj;
itemobj.hItem = tvroot;
itemobj.mask = TVIF_HANDLE | TVIF_TEXT;
itemobj.pszText = new char[20];
itemobj.cchTextMax = 20;

if(!SendMessage(tvh,TVM_GETITEM,0,(LPARAM) &itemobj))
MessageBox(hWnd,"err2","asdf",MB_OK);
else
MessageBox(hWnd,(LPCTSTR)itemobj.pszText,"asdf",MB_OK);


263290 is the handle of a TreeView control present in another window. I'm getting the "err2" MessageBox. If I get the number of items in the TreeView by using the TVM_GETCOUNT message, it works fine. It gives me correct number of items. But why isn't it grabbing the attributes of root item i specify in mask?
