Update Treeview Item using TVM_SETITEM?

[newAsm]

Hi,

Need help from anyone who has created a treeview and needing to update the item label. Which control message should I use?

I had a routine that inserts the item (e.g. "Parent" label) into the treeview. The user can change that item label (e.g. from "Parent" to "Child"). I tried using TVM_SETITEM but would not work. The application crashed.

         mov      eax,[hParent]                                            ; EAX = Patent handle
         mov    tvis.hParent,eax
         mov      tvis.itemex.imask, TVIF_TEXT                      ; set mask to text change
         mov    tvis.itemex.pszText,esi
         mov      eax,[hLevel]                     ; item handle
         mov      tvis.itemex.hItem,eax               ;
         invoke    SendMessage,hTvwGroup,TVM_SETITEM,0,addr tvis

The application crashed at SendMessage. Does anyone know what have I done wrong?

Thanks...newAsm

Are you sure your TVITEM/EX structure is correct? -- I don't see the hParent in either of them

Also, try using the plain old TVITEM struct instead of the extended version..

Thanks Tedd, for asking if I used the right structure. You are right, I used the wrong structure. I have fixed it.

Thanks for responding..newAsm
