Hello
I have created 260 bytes using GlobalAlloc and GPTR flag, the return is successful.
I have stored the returned address in the lParam member of TCITEM successfully.
when my program terminates I try to free the allocated memory but lParam is 0 and SendMessage returns 0 as well on some of the items.
what could be the problem?
this is my log file, and if you notice the addresses of tab 1 and 2 are incorrect but that is what SendMessage returned to me???
thank you

thank you
when you delete, the index of the item changes
you should call DestroyPage in a loop with a parameter of 0 (so you always delete the first item), not ebx
