No I didn't, try it.
what he wants to do is having the compiler enforcing it and the code I posted will just do it.
The interface will require the class to implement the method, normally that wouldn't be enough to enforce to rewrite it because it's already implemented by a parent class, but because it's protected and not public or internal, the child class won't see it and therefore the compiler requires the implementation of the interface.
I didn't say it but it should be obvious that both methods (in the interface and the abstract class) need to have the exact same signature, that is, same name, same return type and same parameters.

How can I enter in a textbox(for example textbox1) a list of coefficients and convert this list of coefficients from input string to an array of doubles so I can use it to obtain numerator and denominator of a function? Help me please cause I am a beginner.Best regards

I don't know how you separate each number, but let's assume it's comma separated values, like 1,3,9,75.
The first thing you have to do is separate this values, you can use the Split method of the string class.
char[] separator = new char[1];
separator[0] = ',';
string[] numbers = textbox1.Text.Split(separator);
double[] coeficients = new double[numbers.Lenght];
for (int i = 0; i < numbers.Lenght; i++)
{
try
{
coeficients[i] = double.Parse(numbers[i]);
}
catch
{
}
}

I have 2 functions PlaySound() & PlaySound_1, I want the PlaySound() will run when Form_Load & the PlaySound_1() will run when a specified function is fired.
And both of those sound don't stop others sound.
How can I do that? Thanks!
Hung!
private void PlaySound()
{
try
{
Sound.PlaySoundWin32("LoopyMusic.wav", 0, (int)(SND.SND_ASYNC | SND.SND_NOSTOP | SND.SND_LOOP));
}
catch
{
if (System.IO.File.Exists("LoopyMusic.wav"))
{
Sound.PlaySoundWinCE("LoopyMusic.wav", 0, (int)(SND.SND_ASYNC | SND.SND_NOSTOP | SND.SND_LOOP));
}
}
}
private void PlaySound_1()
{
try
{
Sound.PlaySoundWin32("time.wav", 0, (int)(SND.SND_ASYNC | SND.SND_FILENAME | SND.SND_NOSTOP | SND.SND_NOWAIT));
}
catch
{
if (System.IO.File.Exists("time.wav"))
{
Sound.PlaySoundWinCE("time.wav", 0, (int)(SND.SND_ASYNC | SND.SND_FILENAME | SND.SND_NOSTOP | SND.SND_NOWAIT));
}
}
}
I have done as follow:
[FORM_LOAD]
Thread thr = new Thread(new ThreadStart(PlaySound));
thr.Start();
[AN EVENT IS FIRED]
PlaySound_1();

Hi
I have a sting with the contents as above. How can I display it?
string sw = "0\0"
MessageBox.Show(sw); // doesn't work
cheers

Hi
In C#, the \ is the string escape character. To include a backslash write either of these:
string sw = "0\\0";
string sw = @"0\0";

Thanks. What should I do if its the output of a function? This is my code:
<br />
CSocketPacket theSockId = (CSocketPacket)asyn.AsyncState;<br />
int iRx = 0;<br />
iRx = theSockId.thisSocket.EndReceive(asyn);<br />
char[] chars = new char[iRx + 1];<br />
System.Text.Decoder d = System.Text.Encoding.ASCII.GetDecoder();<br />
int charLen = d.GetChars(theSockId.dataBuffer, 0, iRx, chars, 0);<br />
string szData = new System.String(chars);<br />
<br />
buffer.Append(szData);<br />
string b = buffer.ToString();<br />
<br />
MessageBox.Show("buffer:"+b+" sz:"+szData);<br />
szData comes as a string with a character followed by a \0
cheers

Thats is becos you are appending a \0! And buffer probably already contains a terminating \0.

You can't display the character \0, there is no character glyph for that character code in any fonts. It's used as an end marker for zero terminated strings. Strings in .NET don't use a terminator character, so you can just trim that character away.
If you want to show that there is a \0 character, you have to replace it with characters that are possible to display, for an example:
MessageBox.Show("buffer:"+b+" sz:"+szData.Replace("\x00", "[0]"));
---
b { font-weight: normal; }

Thanks.
I have another slight problem. When I try to recieve data a second time nothing is recieved. The OnDataREcieved callback runs repetedly with no data. do I need to do something to clear the socket befoer recieving more data.

Hi
I have the following error:
Error 1 Inconsistent accessibility: field type 'System.Collections.Generic.List<u2.friend>' is less accessible than field 'u2.Prog.friends' C:\Documents and Settings\Ben\My Documents\Visual Studio 2005\Projects\u2\u2\Prog.cs 21 29 u2
The Glob class is internal and the Prog class is public.
This is the code that causes the error:
if (Glob.Prog.friends.Count == 0)
cheers

I have a print preview dialog that allways previsualates what is due to be printed. The previsualization work's fine, but the printing fails.
I think that this may occur because at the printing algortihm the document.Print(); is called again.
Is there any posibility to print directly the data previsualizated (into the control) without beeing necesary to recalculate (generate) it (through the document?
protected internal static readonly ... and I wish the list could continue ...

Not in an easy way me thinks

Hi
You can do this by deriving a class from PrintController.
When the dialog "prints" to generate the preview, save the metafiles produced. Then when the dialog "prints" to the printer, just return the saved images.

Can you supply me with a pice of code pls ...
Currently I have no ideea how to achive that ...
BTW, thank you for your answer

Nicholas wrote an article on how to get the meta files of the preview and store them as images. You can find it here[^]. You will have to redirect the meta files into a new print job.
Note that you nevertheless need another PrintDocument.Print cycle but you won't have to regenerate the output.

Thanks, exactly what I had to read before implementing an dirty method for obtaining the PageInfo from the preview control (reflection way). Didn't see the GetPreviewPageInfo() procedure.
protected internal static readonly ... and I wish the list could continue ...
|

If this is the case, (print preview is fine, print is not) then chances are you have some variables not reset somewhere, or set to the wrong value. I would suggest trying to figure out exactly what the problem is before "masking" the problem with another solution.
