Yes, but was an error in IngresaItem, now i cleanup the code and should work
logically:
void GrabaNuevoItem(void)
{
UInt16 NuevoIndice;
MemHandle registroH;
OrderReg item;
Int16 length = 0;
Char *s;
NuevoIndice=gNumOrden-1;
registroH = DmGetRecord(PedidosDB, NuevoIndice);
if(!registroH)
FrmCustomAlert(Mensaje,"Handle null", NULL,NULL);
else
length = (MemHandleSize(registroH)); //Calcule last size of record
DmReleaseRecord(PedidosDB, NuevoIndice, true); // right?
IngresaItem(item.items); //Load from fields to
item.cantitems=gcantitems; //struct,(only item and quantity of items)
//Calcule the size of new item to add to record
length += 16; //In the struct codigo size is 15
length += sizeof(item.items[gcantitems-1].cantidad);
length += sizeof(item.items[gcantitems-1].precio);
registroH = DmGetRecord(PedidosDB, gNumOrden-1); //Open again, ok?
if(!registroH)
FrmCustomAlert(Mensaje,"Handle null", NULL,NULL);
else
if ((MemHandleResize(registroH, length))==0)//Resize the handle, don't problem
{
s=MemHandleLock(registroH); //Lock the handle, i think don't work
IngresaItem(item.items); //I lost the record(�?), load again
item.cantitems=gcantitems;
//Write the records
DmWrite(s,offsetof(OrderReg,cantitems),&item.cantitems,sizeof(item.cantitems));
DmWrite(s,offsetof(OrderReg,items[gcantitems-1].cantidad),
&item.items[gcantitem
s-1].cantidad,sizeof(item.items[gcantitems-1].cantidad));
DmWrite(s,offsetof(OrderReg,items[gcantitems-1].precio),
&item.items[gcantitems-
1].precio,sizeof(item.items[gcantitems-1].precio));
DmStrCopy(s,offsetof(OrderReg,items[gcantitems-1].codigo),
item.items[gcantitems
-1].codigo);
MemHandleUnlock(registroH);//here error in POSE->SysFatalAlert:NULL HANDLE
}
DmReleaseRecord(PedidosDB, gcantitems-1, true);
//Other error: lost program counter
}
this time write the records, (i see with the RscrEdit) but i get these errors
what happend?
