Re: Having problems with an array of objects

Hi Mark,

I had a discussion only yesterday about PRE and CODE tags,
and it is confusing and not satisfying.

the PRE tag seems to give non-prop font, correct spacing (except drops empty lines), background;
the CODE tag seems to give non-prop font, dark red forground color

copying while preserving newlines is completely unclear;
sometimes it works for both PRE, CODE and PRE+CODE
sometimes it does not; I do not understand

And I dont know a magic trick that solves it all.

Regards

I don't think pre drops blank lines:

Let me see...

// Line 1
 
 
 
//Line 5

Oh that's right - I had to ask about that one a while back - add at least 1 space to the line
and the line will stay - so yes, I guess it drops empty lines.

Anyway, I like the way code looks in the pre tags, I just wish I could copy the code right over
to VS. I spend enough time here so it grinds my gears when I have to go through and reformat it.

I guess I could actually research this. Nah.

Thanks!

Hi Mark,

I fully agree.

One should be able to copy source code from VS into whatever tag is required in a message
to get it shown at its best; and to copy code from a message back to VS, without any
hassle.

AFAIK that is not the case:

1.
empty lines (without a single char) get thrown out of PRE

2.
and copying from message to elsewhere may or may not succeed (i.e. keep newlines)

3.
and then there is the problem with the < sign which triggers HTML interpretation;
if you're lucky it does not start a valid HTML tag and it will show as intended;
if unlucky it will be eaten together with some more characters
(most striking example are the summary,returns,remarks tags from structured comments in C#,
the ones that can be collected into an XML file.

Of course, there must be technical reasons for the current behavior: the message is shown
as HTML text, so we copy what we see (more or less), but we dont see what we type or paste;
nevertheless we want to be able to paste, then copy with no change whatsoever !

I'll try to do some more research on this, resulting hopefully in:
- either some guidelines as to how best to use what is available
- or a new request towards the webmaster(s)

Luc,

Here is an odd twist. If I am using the CPSyntax, and take the

// Line 1
 
 
 
//Line 5

and paste into VS, I get...

1. // Line 1
2.
3. 
4. 
5. //Line 5

This happens in Notepad, as well. Disabling CPSyntax, all is good Suspicious | :suss:

Interesting, much better, but not perfect either, it still interprets inside a
pre block, turning text to bold (as is normal in HTML).

I will be looking for actual CP messages with code blocks that look good and
either do or dont let them being copied while keeping newlines intact, so I can
study the source (as in "View Source" on IE).

That's what I'm talking about. I like to run code, not just try to read it, especially when an
OP posts a couple pages of code. I DON'T like having to format it so I can look at it without
my eyes bleeding Smile | :)

I'm waiting for Luc to figure it all out...

Luc and I went into a fair discussion about this yesterday or so. To make things more strange, I've used CPSyntax and it has made things go weird.

CPSyntax is a Grease Monkey script done by Shog to pretty up code in the forums. The code shows up in lines of alternating white/light bluish lines. It was nice until I noticed the copy/paste matters. I may drop Shog a note about it...

Well I switched to FF after these discussions yesterday. It fixed all my code formatting and copying
gripes except for one - I wish the angle brackets would be left alone in pre formatted blocks.
Sure it's not HTML but there's very few tags supported anyway.

Now all of the sudden I see links view plainshow original copy to clipboard print? And it works fine when using the copy to clip board. I wonder why I see it on my desktop, but not the laptop? Suspicious | :suss:

Cool, I got something to research around on this morning Smile | :)

Mark, I agree!

If you use the forum editor, you can write the following:

<pre><code>
x += 2;
y += 3;
</code></pre>

The editor converts it to this:

<pre><code>
 x += 2; 
 y += 3; 
</code></pre>

Thus, when you copy the code, the HTML tags get stripped out and you have just one line of code. Frown | :(

I've been browsing the HTML code as well...

I forgot one other wish - within a block of code that keeps its spacing and newlines and allows
me to bold or color specific text, I'd also like HTML tags turned off so when I post code I don't
have to go through and manually change the angle brackets (I always miss some too).

Luc,

I think the problem, in part, is Visual Studio. I have copied some sample code from code project into Microsoft Word, and it retained the format. I, then, copied the code from Word into Visual Studio, and everything looked as expected. I only used a small sample however.

You need to create them at some point. Wherever is appropriate - CCoordinate class constructor
maybe?

Create them the same way you create the OriginalData array?

I can't get it to work. I added the constructor for the value CCoordinate class and got the compiler error message "value types cannot contain user-defined special member functions". So I changed the class definition to "ref class CCordinate" and this allowed me to create the constructor and add the array definitions in the CCoordinate constructor. But this broke another part. I had to change...

array[CCoordinate, 2]^ OriginalData; To the following line...
array[CCoordinate^, 2]^ OriginalData; to keep from getting the "need an upper level ^" error.

This all compiled but I can't access any of the variables. Most of CLI is pretty cool but the way they put together the arrays is for the birds. I cna't seem to wrap my head around anything other than a one dimensional array of a basic type (such as int). I can create an array of handles (such as int^) but then I can't below System::Array. Native arrays make so much more sense but CLI won't let me use a native type.
