Hi,
I was wondering if it would ever be possible to do things like
for example: put music into 1kb without quality loss or something like that?
I didn't know in what forum to place it and since I program in C# I thought let's post it here.

It doesn't seem likely to me. It would requre on heck of an algorithm.

Let's face it, you can't store any sensible amount of data (music, video, code) in 1024 values with a range of -127 to +127.
It's just not possible.

That will depend entirely on your definitions of music and quality.
If you want to reproduce an existing recording, you will need lots more.
If you have the perfect electronic instrument and all you want to remember is a few pages
of the score, then it can be done.

No, that's not possible.
Any piece of data contains a specific amount of information. You can't compress anything to be smaller than that amount without losing quality.
Generic lossless compression, like rar or zip, can typically compress data to 50%. Specialised compression, like png, can do slightly better, perhaps 30-40%. The theoritcal limit perhaps is 20%, and future compression algorithms will get closer to that, but never below.
If you are talking about compressing a song into 1 kb, that would mean compressing it to something like 0.005%.

I don't know which article do you mean by this articles shows a similar thing: SlideShowBuilder[^]

A quick look shows that I can find solution in this after some cropping
Thanks and Regards

You can use mydataset.Tables.Remove() or mydataset.Tables.RemoveAt()

hi
you dont need iss to run remote connections in sql server 2005 express.
try this link:
link
i've also had to set a specific dynamic port for all ip's.
In SQL Server Configuration Manager choose SQL Server 2005 Network Configuration and Protocols for server name (default SQLEXPRESS).
Now choose TCP/IP and in IP Addresses tab in IP ALL set TCP Dynamic Ports to something else.
If your SQL Server is on pc which connects to internet thats all, if not you must direct chosen port to your pc with SQL Server (it's IP adress in LAN)

Hi again i´m 95% finished and i cinya need this code.
Would appreciate if you helped me.;)
This is the question:
i have one listview1 with timer hwo gets the subfoldername and count files in it and gettime.now. i want to comare subitems[0] and [1] to another listview.
like this
listview1:
Online, k44101, 2007-09-09 21:44:21, , ,122 sides,
listview2:
Online, k44101, 2007-09-09 19:24:20, blahblah.
If [0] and [1] match like this example i want to pass subitem[3](blahblah) to listview1.subitems[3] and calculate 21:44:21 - 19:24:20 to get the work time like this example are 2:20:01 and pass that to listview1.subitems[4].
Can you help me get started?
This is my first program and i have to be finished this week
I have googled and searched in the internet but i don´t find out how to compare.
tnx mates!!!!;P;)

It depends on whether or not you are comparing strings or the date/time values. With strings you can obtain the item's text (Item[n].Subitems[0].Text) at that desired index (n) in each of the the listviews. Then compare the strings.
if( String.Compare(str1, str2) == 0)
{
}
OR...,
if (CultureInfo.CurrentCulture.CompareInfo.Compare(str1, str2,
CompareOptions.IgnoreCase) == 0)
{
}If you are checking the date/time. You need to convert the string to DateTime format then check it using:
DateTime t1 = DateTime.Parse("2007-09-09 21:44:21",
CultureInfo.InvariantCulture.DateTimeFormat);
DateTime t2 = DateTime.Parse("2007-09-09 19:24:20",
CultureInfo.InvariantCulture.DateTimeFormat);
if (DateTime.Compare(t1, t2) > 0)
Console.WriteLine("t1 > t2");
if (DateTime.Compare(t1, t2) == 0)
Console.WriteLine("t1 == t2");
if (DateTime.Compare(t1, t2) < 0)
Console.WriteLine("t1 < t2");Of course the time date string does not have to be a literal.

str1 and str2 are strings from subitems??
It gonna work like this:
when items adds in listview1 it gonna compare subitems[0] and [1] with subitems[0] and [1] in listview2. if they match, pass info listview2.subitems[4] to right item in listview1 and calculate the time... and remove that item in listview2!
How would you do??;P (some code strip)
even hard to excplain!
Appriciate this man!!!

I understand what you are trying to accomplish. You should read up on the properties of the ListView control. When you fully understand the properties you will have no problems accessing and manipulating ListView strings.
The Items collection contains all the indexed items (0,1,2, etc), each Item can have SubItems (0,1,2, etc). For example, suppose I want to get a filepath from the ListViewItem that I have found. The path is the second subitem and the filename is the first subitem.
ListViewItem lvi = fileListView.Items[9];
string filename = lvi.SubItems[1].Text + @"\" + lvi.Text; Now that I have the string I can do something with it (Compare!?). Be careful when iterating through lists and indexing items. If the you try to access an index that is more or less than the "Count" property of the ListView. It throws an System.ArgumentOutOfRangeException error.

Look at the examples there too.

ok... i check it out..
string[] lines = System.IO.File.ReadAllLines("dataapplikationer.txt");
Int32 index = 0;
while (lines.Length >= index + 10)
{
if ("#" != lines[index].Trim())
{
index++;
continue;
}
String appl = lines[index + 1];
String path = lines[index + 2];
String dest = lines[index + 3];
String pris = lines[index + 4];
String sort = lines[index + 5];
index += 10;
System.IO.DirectoryInfo subDI = new System.IO.DirectoryInfo(path);
foreach (String sub in Directory.GetDirectories(path))
{
foreach (String file in Directory.GetFiles(sub, "*.ini"))
{
String row5 = File.ReadAllLines(file)[4];
String section = row5.Substring(9, 6);
String subName = sub.Substring(sub.LastIndexOf(@"\") + 1);
DateTime time = DateTime.Now;
ListViewItem item = new ListViewItem(new string[] { sort, subName.ToString(), time.ToString(), "Summa tid", section, "AD", pris, appl });
this.listView2.Items.Add(item);
this.listView2.AutoResizeColumns(ColumnHeaderAutoResizeStyle.HeaderSize);
}
}
}
but how do i build it together in this code i want the sort, subName.Tostring() to compare in all items in listview1 and if it founds one equal then calculate time "summa tid" and pass by "av"??
Please man! help me build it together... peace!
