A frmCloseEvent may cause some memory to be released. In particular, if there is memory in a field, it will be released on frmCloseEvent (specifically FrmDeleteForm takes care of this). However in general, FormClose will NOT cause memory to be released. Indeed, the general rule of thumb is:
If you allocate, you must de-allocate. As a matter of form, if I de-allocate memory that a gui object knows about, I also tell the gui object that (i.e., set the releavant handle or pointer or whatever to NULL -- or, "if you give it to the GUI, you must take it from the GUI".) I would suggest that your clean-up code may not have been quite correct. -bob mckenzie, palmsource pdx -----Original Message----- From: N [mailto:[EMAIL PROTECTED]] Sent: Monday, October 07, 2002 1:20 PM To: Palm Developer Forum Subject: LIST MEMEORY LEAKS *Please correct me if you find any of my assumption wrong. I have this test application contains two forms. Both form contains a list which is populated from database on FrmOpenEvent. I have a function which allocates memory and populates data and Callback function to draw list. When I exit my application it gives me one memory leak, no matter how many times I toggle between these two forms. So I reached to a conclusion that FrmCloseEvent automatically realse the memory of a form if you are jumping to second form. I don't have any cleanup code on form close event. If I write code on FrmCloseEvent MemPtrFree(ListData) ; handled = false ; Application crashes when I try to jump to second form, if I exit application from first form I get no memory leaks and any crashes. Please help me understand this issue and suggest any solution. Thanks in advance. __________________________________________________ Do you Yahoo!?
