Getting lParam from a list view item.

I'm trying to get the pzsText and lParam variables out of a list view item.

Code:

---

//declaration of LVITEM struct
        LVITEM lvit;
        ZeroMemory(&lvit, sizeof(lvit));
        lvit.mask=LVIF_TEXT|LVIF_PARAM; //I want to get the text and lParam of the item
        lvit.iSubItem=2; //from the 3rd column
        lvit.cchTextMax=20;
        lvit.pszText="";


        for(int iteration=0; iteration<atoi(iterations); iteration++)
        {

                for(int i=0; i<ListView_GetItemCount(hwnd_ListView); i++)
                {
                       
                        lvit.iItem=i; //item
                        ListView_GetItem(hwnd_ListView, &lvit); //This line fails

                }

        }

---

When it reaches the failing line, the debugger shows the following message:

Unhandled exception at 0x7c80a268 in PDS.exe: 0xC0000005: Access violation writing location 0x00448e16.

I couldn't find a function which directly gets lParam, so I tried with ListView_GetItem()

I'm really stuck here, thanks for any help.

How about if you allocate some memory for your pszText instead of setting it to "" - the latter makes it point to an empty string that is non-writable, and the address you are seeing the failure at indicates a non-writable memory location [of course, not guaranteed, it could be bad in some other way, but the address isn't at the end of a page, so that's not what's bad with it].

Thank you! That helped.
