Hi Phil Are you sure that the first code doesn't work ? Ther is no need to duplicate the content, as far as you have the pointer and can access the contents through it.
The only need of second FrmSetTitle in code 1 is to trigger title redraw. The PalmOS code might compare the old and new title addresses and avoid redrawing in case they are same. This might be an explanation of your case. Correct me if I am wrong. I case code1 really doesn't work, I would try the following trick: static Char buf[32]; StrCopy(buf, "Philip Sheard"); FrmSetTitle(frm, buf); StrCopy(buf, "Michael Glickman"); FrmSetTitle(frm, NULL); // Sic! FrmSetTitle(frm, buf); This might work.

To make sure, I had a look at the source code. I was struck by just how similar the two routines are. They *both* cater for overlapping. So how come the overlapping problem only occurs in the latter? The answer is that it does not. It is just that the original title has to persist until after it has been replaced. So this will not work: static Char buf[32]; StrCopy(buf, "Andy Yeong"); FrmSetTitle(frm, buf); StrCopy(buf, "Joanne"); FrmSetTitle(frm, buf); But this will: static Char buf1[32], buf2[32]; StrCopy(buf1, "Andy Yeong"); FrmSetTitle(frm, buf1); StrCopy(buf2, "Joanne"); FrmSetTitle(frm, buf2); Or at least I think it will. I have not checked it, but inspection of PrvRedrawTitle reveals why it should (and why FrmCopyTitle works). The first call to FrmSetTitle stores the address of the title, but not its contents. The second call to FrmSetTitle uses the current contents of that address, to calculate the length of the original title. In other words, the original title cannot be discarded until after it has been replaced. I still think that FrmCopyTitle is a better solution in most instances, as it obviates the need to allocate temporary storage. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
