My SaveDate routing writes one record into the
database but the actual form fields (code and notes)
and the bitmap are not saved with the record. Where
did I do wrong? Thanks much.
/* db record structure */
typedef struct{
Char *code;
Char *notes;
BitmapType *signature;
}DBRec;
static void SaveData()
{
WinHandle win;
Err error;
BitmapType *bmpP;
RectangleType rect;
MemHandle newrecH;
DBRec newrec;
DBRec *newrecP;
UInt16 ind = dmMaxRecordIndex;
rect.topLeft.x = C_X;
rect.topLeft.y = C_Y;
rect.extent.x = C_EX;
rect.extent.y = C_EY;
/* turn palm drawing to a bitmap */
bmpP = BmpCreate(C_EX, C_EY, 1, NULL, &error);
if (bmpP)
{
win = WinCreateBitmapWindow(bmpP, &error);
if (win)
{
WinSetDrawWindow(win); //not sure if this is needed
WinCopyRectangle(NULL,win,&rect,C_X,C_Y, winPaint);
}
WinDeleteWindow(win, false); //done with the window
/* save data and bitmap to db */
newrec.code = GetFieldText(MainCodeField);
newrec.notes = GetFieldText(MainNotesField);
newrec.signature = bmpP;
newrecH = DmNewHandle(gDB, sizeof(newrec));
newrecP = MemHandleLock(newrecH);
DmWrite(newrecP, 0, &newrec, sizeof(newrec));
MemHandleUnlock(newrecH);
DmAttachRecord(gDB, &ind, newrecH, NULL);
}
BmpDelete(bmpP); //saved, no longer needed.
}
/* read text from text field */
Char* GetFieldText(UInt16 ID)
{
FieldPtr pField = NULL;
Char* pText = NULL;
if ((pField = (FieldPtr)GetObjectPtr(ID)) != NULL)
{
pText = FldGetTextPtr (pField);
}
else
{
pText = NULL;
}
return (pText);
}
