Re: How Can i maximize windows throug coding in c#?

17-Jun-07 22:13

First step - buy a book like Inside C# and work through it. This will teach you C#
Second step - buy a book on windows forms and work through it. This will teach you forms programming in C#
Third step - try google when you're stuck.

The WindowState property is how you maximise a window.

Please don't spam the entire site. To do this is not trivial, you need to either record all the words you want to say ( brute force ), or you need to record all the different sounds in your language and write a parser to work out the sounds from the words.

I don't see how you expect more than this, although this is pretty obvious, when you're asking such a top level question in an online forum.

Sir,
Is there any way else of recordings?
by recording u mean that in Microsoft TalkIt Text-2-Speech application Microsoft had recorded each and every word;which i write to be spoken.whether the word is "My own Name","any word of my own language".It speak each every thing.Howevere Microsoft company is not aware of that word.So how they recorded that word.
Sir,
Hope U'll uderstant what I want to say.In the same fasion I want to build my project.Its writing is only different usiny unicode.
So if u have any idea behind that, then Please tell me Please.
ThanX

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); //Exception<br />

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.

Christian Graus17-Jun-07 21:10

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

Christian Graus17-Jun-07 22:43

17-Jun-07 22:43

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;
}
}
