To use your struct like you are attempting you need to define it as follows:
typedef struct _CODE_POSTAL
{
UInt32 dwCode;
Char szCommune[25];
UInt8 iIndex;
}CODE_POSTAL;
Note: You should not assign a value to szCommune > 24 characters in length.
If you do you may not generate an error but you will be writing over memory
outside of your structure.
A more memory efficent way of doing this would be:
typedef struct _CODE_POSTAL
{
UInt32 dwCode;
Char *szCommune;
UInt8 iIndex;
}CODE_POSTAL;
CODE_POSTAL PostalList[10];
PostalList[0].dwCode = 9420;
PostalList[0].szCommune = MemPtrNew(StrLen("Aaigem")+1);
StrCopy(PostalList[0].szCommune, "Aaigem");
PostalList[1].dwCode = 9420;
PostalList[1].szCommune = MemPtrNew(StrLen("Aalbeke")+1);
StrCopy(PostalList[1].szCommune, "Aalbeke");
PostalList[1].dwCode = 9420;
PostalList[1].szCommune = MemPtrNew(StrLen("Aalst")+1);
StrCopy(PostalList[1].szCommune, "Aalst");
...
If you do it this way you need to free the memory you allocated with
MemPtrNew once you are done with it:
MemPtrFree(PostalList[0].szCommune);
MemPtrFree(PostalList[1].szCommune);
MemPtrFree(PostalList[2].szCommune);
...
If you are new to C programming I highly suggest getting a good C
programming How To book, don't get a C++ book. Although you can use C++ on
the Palm most of what you will do should conform to C programming standards.
