Had the same issue this morning and seems like made a similar mistake.

This line
htmlparser.Parse(sr);

takes a StreamReader not a StringReader.

var stringStream = new StreamReader(GenerateStreamFromString(html));
htmlparser.Parse(stringStream);

(...)

private Stream GenerateStreamFromString(string s)
{
var stream = new MemoryStream();
var writer = new StreamWriter(stream);
writer.Write(s);
writer.Flush();
stream.Position = 0;
return stream;
}

One of these should help:

if (cbSelect1.SelectedValue.ToString() != null && cbSelect2.SelectedValue.ToString() != null)

Could be replaced with

if (cbSelect1.SelectedValue != null && cbSelect2.SelectedValue != null)

and that should solve the problem.
No need to convert to string at this time.

Ps. a Quote from another post:

We can convert the integer “i” using “i.ToString()” or “Convert.ToString” so what’s the difference.
The basic difference between them is “Convert” function handles NULLS while “i.ToString()”
does not it will throw a NULL reference exception error. So as good coding practice using
“convert” is always safe.

Reload the sound file in your form application after it has been replaced on your "Web".

replace textBox1.AppendText("Friend: " + receivedMessage); with textBox1.AppendText("Friend: " + receivedMessage + Environment.NewLine);

Could this help ?

Also this works in a similar way as app.config:

Hi
That depends on what plotter you are using. It is safe to say that whatever language your plotter is using it will be similar to HPGL or a clone of it. http://en.wikipedia.org/wiki/HPGL

The way to communicate with the plotter is usually via serial, virtual serial over USB or parallel port of your computer.

Here is a good starting point if your plotter is a Roland :

I haven't used plotters in years so this info may be outdated but it is certainly a good starting point.

As to the API there isn't one as such as the communication happens by directly talking to the device by either serial :

or parallel port:

Thanks

Wouldn't setting AutoGenerateColumns="true" solve your problem ?

Perhaps this is not the best time to change the hid library now but this one reads the device asynchronously :

What do you mean by "automatically by default" ?
