If you want to store data into a database, the call you want to use is
probably DmNewRecord, rather than MemHandleNew.
As others have said, you can't store Char* variables into a database;
you need to store the strings that the Char* variables are pointing to
into the database.
As a quick example, if you have three variables:
Char *a;
Char *b;
Char *c;
that you have pointing to some valid, null-terminated data, the way
you'd store this into a database record (in database db, which was
already open) is something like the following:
UInt16 len = StrLen(a)+1 + StrLen(b)+1 + StrLen(c)+1;
UInt16 indx = dmMaxRecordIndex;
MemHandle h = DmNewRecord(db, &indx, len);
if (h)
{
Char *xx = (char *)MemHandleLock(h);
if (xx)
{
UInt16 pos = 0;
DmWrite(xx, pos, a, StrLen(a)+1);
pos += StrLen(a)+1;
DmWrite(xx, pos, b, StrLen(b)+1);
pos += StrLen(b)+1;
DmWrite(xx, pos, c, StrLen(c)+1);
pos += StrLen(c)+1; // this really isn't necessary, but it's here
// for clarity
MemHandleUnlock(h);
}
DmReleaseRecord(db, indx, true);
}
To read the variables from the database, you do something
similar. This is called packing and unpacking, and is a pretty common
way of storing strings into Palm databases.
