Hello,
I have been trying to render an SVG file on a form, but I can't seem to get it right. The main thing I need is to get SVG files onto the main form, and the possibility to scale them without loss of quality. I have been trying some things with Svg.Net, but to no avail.
Maybe I am missing a really obvious thing, but I would sure appreciate it if someone could give me some pointers.
Thanks in advance! 
Kind regards,
Johnny

The really obvious thing to me would be to put a browser control in your form and let it render the SVG ?

Thanks, that would be a good idea, but we need to render and scale icons for Points Of Interest for a route navigation application ourselves. We also need to scale those icons dynamically. Drawing the map is done in a PictureBox, so a browser control is really not an option.

Hi All,
I wanted to share this with anyone who may stumble across this thread.
X.690 specifies a BMP string is the 2-octet canonical form (specified in ISO/IEC 10646-1) [1] of UCS (also specified in ISO/IEC 10646-1) [2]. Note that ASN.1 does not include an "Endianness" marker in its octet stream [3].
ISO 10646 prefers Big Endianness, though it is not standardized [4]. According to Microsoft, CodePage 1200 is Unicode (UTF-16), and CodePage 1201 is Unicode Big Endian (16 bits also)[5].
In memory, the byte[] from the ASN.1 sequence is [00 77 00 105 00 99 00 114 00 111 00 115 00 111 00 102 00 116 ...]. This is a Big Endian Serialization [6] from Microsoft's Cryptograhic Service Provider.
When interpreted as Unicode, I receive a non printable string. When interpreted as Big Endian Unicode (CodePage 1201), I receive 'Microsoft'.
So, a test of byte[] (Value[0]) is required to properly return the string. The return will be either Encoding.GetEncoding(1200).GetString(Value); or Encoding.GetEncoding(1201).GetString(Value).
Simply using Encoding.Unicode does not produce expected results in every case, since Unicode implies Little Endianness when using C#.

I'm trying to follow a guide in a book. It tells me this line:
wave = new DirectSound.SecondaryBuffer("laser1.wav", sound);
and gives me several more lines. Yet I try this and more wave files and I keep getting the same error.
SoundException was Unhandled
What do I do to make this work, because, I QUOTE from the book, "this is amazingly simple". Thanks in advance.

You might want to try specifying the fully qualified filespec (this is always a good idea) instead of simply laser1.wav. It's also a good idea to catch possible exceptions, eg:
try {
wave = new DirectSound.SecondaryBuffer("C:\\laser1.wav", sound);
}
catch (SoundException ex) {
}

Could it be a wrong version of DirectSound? Here's the full code.
(one line above...)
private void PlaySound()<br />
{<br />
DirectSound.Device Sound;<br />
DirectSound.SecondaryBuffer Wave;<br />
DirectSound.BufferDescription Description = new DirectSound.BufferDescription();<br />
Description.ControlEffects = true;<br />
<br />
Sound = new DirectSound.Device();<br />
Sound.SetCooperativeLevel(this, CooperativeLevel.Priority);<br />
Wave = new SecondaryBuffer("song1.wav", Description, Sound);<br />
Wave.Play(0, BufferPlayFlags.Default);<br />
}

What's the message of the exception you caught?

That's also what it gives me in the book. I probably shouldn't deviate too much.

Sorry, I don't understand what you're saying. What is "that"?

"laser1.wav" I don't know what to do, and I;m also trying articles on the net too.

Well for one you could try what I suggested doing. See my first reply in case you've forgotten.

What does that do? Or how would I do what you're suggesting. I really don't know C#, my friend.

Specifiying a fully qualified filespec guarantees that your code will attempt to operate on a file that exists.
MasterSharp wrote: how would I do what you're suggesting.
Edit the code and recompile and re-run your program.

I'm sorry that I'm pushing my help and all, but what would I do in the catch part, to find out? I added the code, except for that.

I tried it without code in catch, and it doesn't stop the program and give me an error, but I don't hear sound.

I got the error code from "ex". 2147287038

That's probably because you're "eating" the exception (i.e. catching it but not doing anything about the fact that an exception was thrown).

MasterSharp wrote: what would I do in the catch part
The simplest thing to do would be to display a message box if an exception is thrown, eg:
try {
wave = new DirectSound.SecondaryBuffer("C:\\laser1.wav", sound);
}
catch (SoundException ex) {
MessageBox.Show (ex.Message);
}
Also make sure the file C:\\laser1.wav exists.

Ok, so now that we have that done, how could we get the sound to play? I tried severl wave files I see listed in my files, and nothing works. I just want some sounds!

Was an exception thrown? If so, what's its message?
/ravi

The error is:
"error in the application - (that big number from a post or 2 ago, Unknown)
string filename, bufferdescription, Device parent
