No. They recorded each and every SOUND used to make up a word. This results is several THOUSAND different sounds that your code has to pick from and string together to make the sound of a word.
This is no trivial task. If you're working on this by yourself, it'll take you about 10 years to do. If you have a team of people who know what they're doing, 2 years to build the phonetic sound library. The rest of the code would probably take about 3 months to put together since you could probably find a pulic source for English code and modify it for your language. But without the phonetic sound library, the code is useless.

Hello,
I have a strange problem in dotnet framework 2.0. When I want to serialize a class which has a member property from type DateTime then I get a NullReferenceException. The DateTime object has an valid value...
<br />
SoapFormatter serializer;<br />
<br />
serializer.Serialize(ms, logMessage);
What I have to do, so that I can serialize an DateTime object with the SoapFormatter?
Best regards

Hi,
Does anybody know a good reference documentation/tutorial/code where we can learn how to manipulate excel sheets using C#/VB.Net? Like filling cells with values, cut, copy paste rows/columns, formatting cells, adding charts to the excel sheet, etc.
Thanks
Anil

in what way should i write new file in .wav format to be played as a .wav music.currently data hiding is success but the file is not playing.

What have you done, and what do you hope to do ? Where is the data coming from that you hope will play as a wav ?

You'll have to be more descriptive than that. How, exactly, are you hiding the text file. I mean, are you just writing out a text file but putting a wav file extension on it. I'd hope you were being more sophisticated than that. Are you ensuring the WAV header isn't being corrupted by your hiding process? Are you hiding the data in a way that is still compliant with the codec in which the audio information is encoded?

OK - so you want to hide a text file, so the wav still plays ? Sounds like your core approach is broken and you need to better understand the wav file format, to learn how to hide data in there non destructively.

i checked the header of newly created file.it is same as the original wave file.i'm writing the new file in bytes.its playing but no clarity in sound
|

Well, what did you expect, when you changed the sound file to have some text shoved in there ? I'd expect changing a wav to be much harder than hiding text in an image.

Hey guys,
I need to add about 7000-14000 items to a listview.
But listing all the items is far too slow.
Do you have any idea how to make it faster?
thank you very much!
I use the following method:
private void trvLeft_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
DataRow[] rows = new DataRow [PnlSelect.pMCPTVARIABLEDESC .Rows.Count ];
System.Windows .Forms .ListView .ListViewItemCollection itlist= new System.Windows .Forms .ListView .ListViewItemCollection(lsvLeft);
try
{
lsvLeft.BeginUpdate ();
Cursor.Current =System.Windows .Forms .Cursors .WaitCursor;
//Clear old content:
lsvLeft.Clear ();//lsvLeft is my ListView
pTrvLeftTag=(TrvLeftTag)e.Node.Tag ;
rows=PnlSelect.pMCPTVARIABLEDESC .Select ("VARGROUPID='"+pTrvLeftTag.vargroup +"' AND CONNECTIONID='"+pTrvLeftTag.connection +"'");
foreach(DataRow row in rows)
{
itlist.Add(row["VARIABLENAME"].ToString ());
}
//add images
foreach( ListViewItem it in lsvLeft.Items )
{
it.ImageIndex =6;
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message );
}
finally
{
lsvLeft.EndUpdate ();
Cursor.Current =System.Windows .Forms .Cursors .Default;
}
}

Well, that's not really a sensible UI. You probably need to show a filtered view. How is someone going to navigate these 10000 odd items ?

7000-14000 items?? Why on earth would anyone want to go through that many items? I think you have a bit of a design flaw in your UI.

hi,
It is important to show all those items, it should not be a design flaw.
My Listview should contain all variables of a industrial plant.
the user should select about 10 variables from that listview and these 10 variables will be shown in an configurable protocol afterwards.
I reading my data out of an SQL-table which is filled by the Siemens visualization software WinCC.
The problem is that there are so many variables.
I have decided to use a listbox now. I doesn't look as good as a listview and has not that much option, but those 100000 items are there in a minute...
i do not have other ideas...
kind regards

Actually, it IS a desgin flaw, on your part. Noone is going to go through a list of 14,000 items to pick 10 of them.
Redesgin you interface so the items are seperated into logical groups so the user can narrow down the list to just the items in a particular group.
If you put 14,000 items into a list view and expect someone to look through them all, I guarantee you the users will hunt you down and shove the installation CD where the sun don't shine.

.AddRange() ?
But, yeah, that's a lot of stuff. Some sort of filter would be good.

Hi,
I will not discuss if it is reasonable to display that much lines - you say you need it's ok for me.
I bump in a similar problem , I needed to add lines (trace lines) on a screen as fast as possible.
I made several experiment : listBox , listView, richTextBox , (even webBrowser ...)
It turns out that richTextbox was the fastest , and that the speed to add new line was constant , whatever was the numer of lines already added.
Of course in this case you shouldn't add lines one by ones , but all in one call.
Just set the rtb not to be editable.
Even handle the line selection by yourself.
And you will get a super fast , super basic ListBox 
Hope it helps

Hi girm,
thanks for your answer,
yes, sometimes it is necessary to add as many lines as mentioned.
I think Listbox ist the best option to use in this case.
my code snippet:
this.ListBox1.DisplayMember ="column";
this.ListBox1.DataSource =dt;//dt: DataTable
regards
