The problem is that you need to take your raw resource (an .mp3 file or similar) and generate a DirectX.AudioVideoPlayback.Audio object from it. I don't remember offhand, does Play() allow passing in a stream instead of a file name? From there, you could get your resource object as a byte[], put it in a stream, then play the song from there.

Hi,
I get the following error in an application.
System.Runtime.InteropServices.COMException (0x80040154): ?
I have set up a test machine where I can reproduce the error and it seems to be at a point where I am using SQLDMO to connect to a database. The wierd thing is that it works fine on my machine but not on a workstation. the only difference between the machines as far as database is that I have SQL Server 7.0 on my machine and the test machine does not.
How can I find out what is needed to resolve this issue as far as files etc?
Thanks

0x80040154 is an HRESULT error that translates to "Class not registered."
Do you have MDAC[^] installed on the test machine?

MDAC installed fine when I installed the framework for .NET.

Then look for another object that is using COM. The HRESULT is very clear: the object you are looking for is not registered and therefore can not be created let alone call any function upon.

Hi all
i have a tab page form. One tab has a file dialog that searches for a file on a form, and the other tab has a treeview that is populated with icons. When the form closes and i try to relaunch the form the following code:
myImageList.Images.Add(new Icon(imageFolder + "button.ico"));
goes looking for the icons at the last location that the file dialog returned,.... Why?

Is the RestoreDirectory property set to true?
From OpenFileDialog help:
Gets or sets a value indicating whether the dialog box restores the current directory before closing.

Your code should never assume that the current directory will never change. That's what happening after your file dialog closes. It's changed the current directory.
Let me guess, the value of imageFolder is just a directory name and not a full path?
You should be building a complete full path to any file that your application attempts to get. You could easily accomplish your posted task by creating a small method that returns the full path to the imageFolder directory:
public string GetImageFolderPath()
{
return Path.Combine(Application.StartupPath, imageFolder);
}
Even better, have your function build the complete path to the image file:
public string GetPathToImageFile(string filename)
{
return Path.Combine( Path.Combine(Application.StartupPath, imagefolder), filename);
}
Then all you have to do in your posted code is:
myImageList.Images.Add( new Icon( GetPathToImageFile("button.ico") ) );

I would to create a key (not a directory) within "SOFTWARE\Microsoft\Windows\CurrentVersion\Run" path
RegistryKey myKey = Registry.LocalMachine;
myKey.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run", true);
myKey.CreateSubKey("MyKey");
myKey.SetValue("MyKey", Application.ExecutablePath);
i get exceprion on 3° line of code, and nothing is created, why?

Why are you writing to LocalMachine?
Do you have the permissions nessessary for this?
Cant you write to CurrentUser?

I have an array of bytes which i need to get bits from in 5-bit chunks.
e.g. lets say my byte array has 4 values
0 - 10101010
1 - 10101010
2 - 10101010
3 - 10101010
i would like an array of strings (or whatever, could be bytes with leading 0) that returns to me the values
0 - (000)10101 (first 5 bits of 0)
1 - (000)01010 (last 3 bits of 0 and first 2 bits of 1)
2 - (000)10101 (mid 5 bits of 1)
.
.
so on
How can I do this in C#?
Thanks

Since that's only 32 combinations, why not use a lookup table? Then all you need to do is some bit shifting and and'ing.

This seems overly complex and there are some errors. It seems that the masks should go:
F8, 7C, 3E, 1F
Also, there's two tests for (i % 5) == 3
Instead of changing the mask, why not shift the byte under test and 'or' in the necessary bits from a look ahead byte (which is 0 if at the end of the array). It's a bit complicated (no pun intended) because you have to figure out when to get the next byte, but you should be able to do the whole thing in a loop.

Have a look at the BitArray class. You can feed it with a byte array and afterwards pick the bits one after the other:
BitArray ba = new BitArray(b);
int counter = 0;
string temp = "";
while (counter < ba.Length)
{
int mod = counter % 8;
temp += ba[counter - 2 * mod + 7] ? "1" : "0";
if (counter % 5 == 4)
{
Console.WriteLine(temp);
temp = "";
}
counter++;
}
if (temp.Length > 0)
Console.WriteLine("Left: " + temp);
The formula when accessing the BitArray indexer seems a bit complicated and results from the fact that the bits from each byte put into the constructor seem to be reversed.

Is it just me or does everyone feel cheated when you don't get a feedback wether a solution worked or not? Maybe I am just small...

Whats even worse is that you sometimes dont even get to know if your answer was read or if you have wasted your time because the answer wasnt even read by the questioner.

 Exactly!!

It is good to know. Especially given that some people's command of the language isn't so great and I wonder whether I interpreted their original question correctly in the first place.

No. Feedback is important in all areas. You cannot improve without feedback. Imagine a baby learning to walk. Without the feedback of the sensation of hitting the floor when they stumble they won't know what moves work and what don't.
Answering questions is great as a learning tool and to keep information going. It is amazing how much more information I can retain by helping others. Mainly because the problems they have may not be in the same area I am currently working on, so by thinking about the area they are asking about keeps the information fresh in my mind, so that if I move back to that area I can recall it much quicker.
Sometimes I feel that I can't be bothered answering questions here. If I feel really bad about not being appreciated or that I'm being used I just leave it a couple of days then come back.
So, don't feel discouraged about people not leaving feedback on your answers. There are many people here who genuinely appreciate the efforts made by those who share knowledge.

Hi,
I am trying to get all the farm name attrbute from Xml files thorugh loop
I have to verify conditoion that when farm name is equal to dev1
It should exit from the loop
my code retrieves only one value from farm name dev2 my code does not search for farm name dev2
any body can help me giving me code
XmlDocument doc = new XmlDocument();
doc.Load("c:/farm-config.xml");
XmlNode farm=doc.SelectSingleNode("/root/farm-config/farm/@name");
MessageBox.Show(farm.InnerText);
xml file strucutyue is as given below
Hi,
I am trying to get all the farm name from Xml files.
This is my xml file structure
<?xml version="1.0" encoding="UTF-8"?>
<root>
<farm-config>
<farm name="dev2">
<connection address="localhost1" user="root1" selectedConnection="1" password="daask6">
<lastJob>Copy-All</lastJob>
<lastConnection startdate="2005-05-10" starttime="12:43:23" enddate="2005-05-10" endtime="12:58:32" />
<state>1</state>
</connection>
</farm>
<farm name="dev1">

Well, given your query, InnerText would only return a result if:
<farm name="dev2">Some text</farm>
You may want InnerXml instead.

hi!
Perhaps I've misunderstood you, but XmlNode.SelectSingleNode will always return a single node.
If you want several nodes you should use XmlNode.SelectNodes()...
