[ravjak]

Try using brackets to delimit each expression you are testing in the if statement. Bikram Singh

What happens if pitem != NULL and pitem->pszText = NULL? (Hint: It wont break) I would do the test: if(pitem && pitem->pszText) { // Do the dance... } Papa while (TRUE) Papa.WillLove ( Bebe ) ;

Not working hmmm hardcore hehe. Im testing changing iImage value according to iItem and it seems to be good if I know sequence of adding apriori, which will require some more coding. Anyway its really strage stuff isn't it :confused: Pain is a weakness living the body

Try this case LVM_INSERTITEM: { LPLVITEM pitem = (LPLVITEM) lParam; if(pitem && pitem->pszText) { if( ((pitem->mask & LVIF_TEXT) == LVIF_TEXT)) { MessageBox(okno,pitem->pszText,"",MB_OK); } } break; Papa while (TRUE) Papa.WillLove ( Bebe ) ;

Not working. Plese remind me next time do not take a project for windows. Pain is a weakness living the body

But I thing I know why is it so. According to spy ++ this is a ATL:SysTreeView control. Maybe as a lparam they are sending some other struct than LV_ITEM:confused: Pain is a weakness living the body

Where is it crashing? Papa while (TRUE) Papa.WillLove ( Bebe ) ;

I would do: if(pitem) { if(pitem->pszText) { // Do the dance... } } Bikram Singh

not working too i think this not valid pointer beacuse its not the same address space I had the similar problem some time ago when i wannted to send some char * as wparam or lparam using SendMessage. I had to use WM_COPYDATA then char * goes thru kernel memory and pointer is valid:confused: Pain is a weakness living the body
