correction, should be
err = MemHandleResize(h, MemHandleSize(h)+(len+1));

I'm not sure what you are doing wrong. As I see it to write the data to the
handle you should be doing something like the following:
// global MemHandle
MemHandle h = NULL;
// Append data to whatever is already in handle
void WriteDataToHandle(Char *dataInP)
{
Char *strP;
Err err;
hi everbody, i am new to palm and its memoryhandles.
I receive a string and have to store it in a MemHandle, because i resize it
in a loop while receiving the data. However, i´ve got no idea how to read
the data from the handle, neither a normal (char*) cast, nor a sprintf
works. I´m sure it is
at first thanx for your reply. However, when i try to access strP my
programm crashes telling me it read memory from the memory manager data
structures. Any idea what i did wrong? i locked the handle to write it,
unlocked it, locked it again by
strP = (Char *)MemHandleLock(h);
accessed strP and
Char *strP;
strP = (Char *)MemHandleLock(h); // h is a MemHandle
if (strP)
{
// Do stuff with strP
}
// Make sure to unlock MemHandle
MemHandleUnlock(h);
