You can in Report. Header/Footer as QTF, $$P as placeholder for the page number.

When using Report::Header(), the stylesheet data is shown also. This is because a bug in Report::FormatHF() method.

The original one was:

String  Report::FormatHF(const char *s, int pageno)
{
	String result;
	while(*s) {
		if(s[0] == '$' && s[1] == '$') {
			if(s[2] == 'P')
				result.Cat(Format("%d", pageno + 1));
			if(s[2] == 'D')
				result.Cat(Format(GetSysDate()));
			s += 3;
		}
		result.Cat(*s++);
	}
	return result;
}

And the fixed one is:

String  Report::FormatHF(const char *s, int pageno)
{
	String result;
	while(*s) {
		if(s[0] == '$' && s[1] == '$') {
			if(s[2] == 'P'){
				result.Cat(Format("%d", pageno + 1));
				s += 3;
			}
			if(s[2] == 'D'){
				result.Cat(Format(GetSysDate()));
				s += 3;
			}
		}
		result.Cat(*s++);
	}
	return result;
}

BTW, this code is very tricky Smile

First I thought, this can generate a segfault. I'm learning every time when reading your code Smile

{
	String result;
	while(*s) {
		if(s[0] == '$' && s[1] == '$') {
			s += 2;
			if(*s == 'P') {
				result.Cat(Format("%d", pageno + 1));
				s++;
			}
			else
			if(*s == 'D') {
				result.Cat(Format(GetSysDate()));
				s++;
			}
		}
		else
			result.Cat(*s++);
	}
	return result;
}

OK?

No, because this filters "$$"s from stylesheet out. My version works well.

Ooops, sorry. But at least, I would insert "else" between two variants ("$$PD"):

String  Report::FormatHF(const char *s, int pageno)
{
	String result;
	while(*s) {
		if(s[0] == '$' && s[1] == '$') {
			if(s[2] == 'P'){
				result.Cat(Format("%d", pageno + 1));
				s += 3;
			}
                  else
			if(s[2] == 'D'){
				result.Cat(Format(GetSysDate()));
				s += 3;
			}
		}
		result.Cat(*s++);
	}
	return result;
}

Yes, good idea. I wanted to pu that else also, but you were faster Smile

"a" and "b"? For what kind of data?

Well, maybe I am wrong, I was never good at these fragile little algorithms, but I think that as there was s+=3 without else, the code would react to the 'D' and "ab" would be skipped.
