Thanks. And Sorry for my English.
Now (this time) I try to understand technique (or technology) of life with UPP and I have additional time to analize expamples.
I found this TOOL is interest and powerful.
And I found one more strange thing in this example.
File borrow.cpp, lines from 14 to 27 - Function
Value DateIntConvertCls::Scan(const Value& text) const
{
String txt = text;
if(IsNull(txt))
return Null;
Date d;
if(StrToDate(d, txt)) {
const char *s = txt;
while(*s == ' ') s++;
if(*s == '\0')
return d - Date(1970, 1, 1);
}
return ErrorValue("Invalid date!");
}
I add there one string return d - Date(1970, 1, 1);.
Value DateIntConvertCls::Scan(const Value& text) const
{
String txt = text;
if(IsNull(txt))
return Null;
Date d;
if(StrToDate(d, txt)) {
const char *s = txt;
while(*s == ' ') s++;
if(*s == '\0')
return d - Date(1970, 1, 1);
}
return d - Date(1970, 1, 1);
// ^^^^^^^^^^^^^^^^^^^^^^^^^
return ErrorValue("Invalid date!");
}
Without this string, I can't to edit Date fields, when I add borrow records. I can add only empty dates.
This may be my mistake or mistake of program.
SQLApp - is a complex example, because many of newbies see to this application and this application is face of system.
And this app must be a exapmle of stability (  ).
