Hi,
simple question
XmlDocument doc = new XmlDocument();
FileStream file = new FileStream
(PathAndFileNam e,FileMode.Open ,FileAccess.Rea d,FileShare.Rea dWrite);
doc.Load(file);
should I now call file.close or do I not need to??
Thanks

Enclose the doc.Load(...) statement in the try-finally block and add the
following in the "finally" clause:
try
{
file.Close();
}
catch(IOExcepti on)
{
// Optionally add something like this here:
// Debug.WriteLine ("Failed to close the file");
}

> should I now call file.close or do I not need to??
yes you should call file.Close(). the whole stream is read in the Load()
method and it's not necessary to leave the file opened.

Hi Nick,
Yes, you should call file.Close(); XmlDocument.Loa d will not close the stream itself. In any case, calling file.Close() on an already closed file will just be ignored and will do no harm.
Happy coding!

after calling close on a FileStream, it will likely become null. the
Close() method of FileStream calls Dispose(). I haven't tested it, but I'm
fairly sure it will be null in all cases.

Calling Close() will release any resources tied to it, in this case the file. The FileStream object will remain intact however, so you can safely call Close() as many times as you want.
Happy coding!

No it won't. Objects don't just disappear because you call Close on
them. If you still have a reference to an object, that reference isn't
going to become null on its own.
the Close() method of FileStream calls Dispose(). I haven't tested it, but I'm fairly sure it will be null in all cases.
Could you clarify exactly what you think "will be null"?

Hi everyone,
I asked another question regarding this same subject about a week ago. See
thread:
http://groups.google.fi/group/comp.lang.c++/browse_frm/thread/cc57b579d6832732/530bae667a479add#530bae667a479add
So, the basic idea is to have a compact logger class which can be used like
the std::cout stream and add extra functionality to it (line numbering, some
output counters etc.).

I have an XSL file that is being applied to an RSS feed, and it works great
except for 2 things:
1.) XSL doesn't close the <img> tag for xhtml even though I have it being
closed in the XSL file (I've tried <img /> and <img></img>). This blows my
xhtml compatibility.
2.) Also, the RSS feed has a namespace "dc", how do I extract data from the

Is this valid:
string allSwitchValues = readSwitches.ReadToEnd().Split('|');
I have no way to test it just yet (although it didn't seem to create
compile errors). Originally I had it divided into two variables on two
lines, but it seems like I only need the one variable, assuming I can't
combine the ReadToEnd and Split methods like so.

I have a UserControl on a form.
The form is closing and I need the usercontrol to write to the Registry.
Where do I do that?
In the Disposed event? I need to do it when controls on the usercontrol are
still active so I can write, for example, the Text value of a Textbox.
In the Overrides Sub Dispose method? if so, before or after the
If disposing Then statement?

Hi newbie here. I am learning c++/cli I by writing console apps. When my
apps finished they used to display a message at the bottom of the screen,
something like "press any key to continue" so that you could see the results
before returning to the IDE. But now they don't. I must have turned a
setting off somewhere but I can't find it. I could code it in but I would
prefer not to.
Any ideas?

Hi,
I'm moving a socket library I wrote from C to C++. In the C version, I
had to malloc char arrays to store incoming communication. My hope was
to use std::string in C++, but then I realized a problem.
While '\0' is a valid string terminator for text, for my purposes it
is a problem. My program regularly gets '\0' as a value (Modbus/RTU
and TCP pass register values as the actual values, not the ASCII
chart). That would be a problem...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
