Hi there,
Having got fed up of constantly picking track lists from large mp3 collections or using crummy auto playlist selectors I was wondering if I could write something better, the only problem is I don't know how to go about getting an mp3's characteristics like it's tempo or pitch etc. 
Does anyone have any samples/info on this type of thing?
a million fang-queues in advance for any titbits you can offer

If I have this kind of question, I use Google and do a little searching. After a couple of minutes I found this on CodeProject itself
http://www.codeproject.com/useritems/mp3fileinfo.asp

Thanks, I did see that article already however and it is not the ID tags that I'm looking to read but the actual music itself.
I did do quite a bit of rooting around google before I asked but so far I've not found any info on calculating the bmp/tempo of a piece of music which is what I'm looking for.

Since the MP3 music format is copyrighted, I would guess that you'd have to purchase a license to the format. That's why you're not getting any hits.

Ahh I see. Thanks for the tip
Does anyone know how to obtain BMP/tempo and pitch information from an unlicenced or GPL music format such as ogg or is it possible to convert an mp3 to another format for processing which avoids these pesky legal pitfalls?
I'm off to copyright the sound of a telephone ringing then go on a litigation rampage!

I have an XML file which has a depth of 4 elements:
-----------------------------------------------
<?xml version="1.0" encoding="utf-8" ?>
<MutualFunds>
..<Fund>
....<FundName>Altamira Fund</FundName>
........<Holdings>
............<Company>
..................<CompanyName>The Procter & Gamble Company</CompanyName>
..................<Symbol>PG</Symbol>
..................<Shares>13500</Shares>
............</Company>
........</Holdings>
....</FundName>
..</Fund>
..<Fund>
....<FundName>Lynch Fund</FundName>
........<Holdings>
............<Company>
..................<CompanyName>Gerber Foods</CompanyName>
..................<Symbol>GF</Symbol>
..................<Shares>13500</Shares>
............</Company>
........</Holdings>
....</FundName>
..</Fund>
</MutualFunds>
-----------------------------------------------
Im trying to read in this XML file and have it parsed so that the contents under <FundName> (Altamira Fund and Lynch Fund) appear in a combobox while its respective <Company>s under <Holdings> are preserved in an ArrayList so that when I select the Altamira Fund from the combobox its respective company's will appear in a ListView.
I've tried tackling this simple problem with:
=[1]=
DataSet ds = new DataSet("MyData");
ds.ReadXml("Holdings.xml");
DataTable t = ds.Tables["Fund"];
=======
=[2]=
XmlTextReader reader = new XmlTextReader("Holdings.xml");
While (!(reader.MoveToContent() == XmlNodeType.Element && reader.Name == "FundName"))
{
reader.ReadString();
}
======
In [1] i tried getting the DataSet to return back a the <Fund> element hoping that it would belong to the Altamira Fund group but it seems the Lynch Fund name was apart of this table. In [2] Im trying to iterate thru the nodes until i get to what I want then begin storing what i need then moving on to the next element. When a </Fund> is reached Ill know the next <Fund> is coming up.
Ideally i want to ask the XML reader to simply return back the <Fund> group of the "Altamira Fund" (which will contain the <FundName>Altamira Fund</FundName>, <Holdings>, and respective <Company> elements). It shouldnt include the other <Fund> in any way. Once I've processed this first fund then i can move on to the next with its respective childern. What Im see from DataSets is its clumping all similar tag contents together, so <Company>'s in both <Fund>s are being placed together. When it comes time to create my ComboBox with respective Company's the presented information will be incorrect. As for the MoveToContent iteration, it seems acceptable but a bit dirty.
Do i "need" to create an XML Schema or use DataRelations in any way?
Thanks.

The easy was is adding a registry entry documented here on MSDN that points to a file containing your script code.
Here's an example of both that I wrote long ago
Save this in borders.inf:
[Version]
Signature="$Chicago$"
Provider=%BCDEV%
[DefaultInstall]
CopyFiles=Files
AddReg=Reg
[DefaultUninstall]
DelFiles=Files
DelReg=Reg
[Files]
%BASENAME%.htm
%BASENAME%.inf
[Reg]
HKCU,%IKEY%,,,"%10%\%SUBDIR%\%BASENAME%.htm"
HKCU,%IKEY%,contexts,1,%CONTEXTS%
HKLM,%UKEY%
HKLM,%UKEY%,DisplayName,,"%TOOLTITLE%"
HKLM,%UKEY%,UninstallString,,"%UCMD% %10%\%SUBDIR%\%BASENAME%.inf"
[DestinationDirs]
DefaultDestDir=10,%SUBDIR%
[Strings]
TOOLTITLE=IE4 Addon - Show Table Borders
BASENAME=borders
CONTEXTS=1
IKEY=Software\Microsoft\Internet Explorer\MenuExt\Show &Table Borders
UKEY=Software\Microsoft\Windows\CurrentVersion\Uninstall\ShowTableBorders
SUBDIR=web
UCMD="rundll32 syssetup.dll,SetupInfObjectInstallAction DefaultUninstall 132"
BCDEV=Blake Coverett Development
And this in borders.htm
<script language=javascript defer>
var tables = external.menuArguments.document.all.tags("table");
if (tables != null) {
for (i = 0; i < tables.length; i++)
{
tables[i].borderColor = "red";
tables[i].border = 1
}
}
</script>
Right click on borders.inf and choose Install. The INF file was meant to be reusable by just changing the strings at the bottom, feel free to reuse it.

Hey, I hope you can help me. I am getting some weird errors when I try to deserialize my object. I can serialize the object without error but when i deserialize i either get an System.OutOfMemoryException or an {"Invalid type code in stream Invalid." }
Here is the serialize and deserialize code:
IFormatter formatter = new BinaryFormatter();
Stream stream = new FileStream(tab.Name + EXT,FileMode.Create, FileAccess.Write, FileShare.None);
formatter.Serialize(stream, tab);
stream.Close();
Deserialize:
IFormatter f= new BinaryFormatter();
Stream s = new FileStream(tableName + EXT,
FileMode.Open,
FileAccess.Read,
FileShare.Read);
ITable obj = (ITable) f.Deserialize(s);
s.Close();
Let me know if you have any suggestions.
Thanks,
Alan Faulkner

I have a DirectX 3-D engine that I want to create some tools for. The tools must have one or more windows to render my 3-D scenes into plus lots of GUI functionality.
I have a win32 app in C++ that displays a 3-D scene using DirectX (graphics code also in C++) so I know I can go that route, but it's tedious to do.
Is it possible (and recommendable) to create the app using C# and hook in the C++ 3-D graphics engine?
Or am I better off sticking with the Win32 framework?
btw, the DirectX code is NOT managed.
thanks,
Rob

I created my very first C# application in .NET and trying to run it from the network. Every time when the application is started, I get a popup message from Microsoft .NET Security Information says:
The application is running in a partially trusted context....
Can you help me to avoid this message? I created the application from C#, Windows Application. The application has no added code on it. Thanks.

Hello.
Thank you very much for series of articles
Image Processing for Dummies with C# and GDI+ .
I have a question that I couldn't find in these articles.
How I can save a high color (16 bit )image as 256 color or fewer.
I want to write this program with C# .net such as previous
articles not with MFC.
I guess the PixelFormat class can be useful. But I don't know how I can use it.
Please tell me how I can write this Program.
Thank you very much.

I'm trying to link a couple of panels that each display a set of fields that extend beyond the visible area, giving rise, of course, to vertical scroll bars. My goal is to arrange it so that moving one panel's scroll bar causes a corresponding action in the other panel. To do so, I need to be able to get a "live" reading on the scroll bar's position. The closest thing I've found is the information in "AutoScrollPosition" which does accurately show a relationship between the current position and the "not moved" position. The problem is, there is no event or other mechanism for getting this information from contact with the scroll bar itself. I can use a click event or mouse-up event to cause the information to be passed to the other control as needed, but it's always disconnected from the actual movement of the scroll bar.
Is there a solution out there that I've just missed? If I have to build a new wrapper control to handle this, I still don't know how to capture the position in real time.
Any ideas, anyone?
Thanks,
David Groves

Welcome to the Wonderful World of .NET AutoScroll. You will need to subclass the panel so that you can catch WM_HSCROLL, WM_VSCROLL, and WM_MOUSEWHEEL messages. And I actually find it easier to just roll my own scrolling panel, and do the scrolling part myself, rather than basing it on an AutoScroll panel.

how to serialize/deserialize derived class between two application? here is the situation:
class container
{
BaseClass bc;
}
class BaseClass
{..}
class DerivedClass1:BaseClass
{...}
class DerivedClass2:BaseClass
{...}
------------------------------------------
the "bc" in the container can be assigned to be DerivedClass1 or DerivedClass2. Those classes and serialize/deserialize functions will be use between two applications (App1, App2). App1 serialize "container", App2 try to deserialize "container".
I tried following ways:
1. Binaryformatter/Soapformatter: During the serialization, App1's name will also be serialized. When App2 try to deserialize, it can not find App1 and generate exceptions.
2. XmlSerializer: it can not serialize when "bc" is assgined to a class other than BaseClass
Any guru have any good method to handle this situation?
Thanks,
Leo
