In addition to what dnh said, look at the System.Xml.Serialization.XmlSerializer object. It can convert an entire class to and from and XML file.

WHAT?? This makes no sense what-so-ever. The Graphics class doesn't represent an image of anything. Perhaps a better explanation of what you want to accomplish would help.

All your drawing on the form surface must be done in the Form's OnPaint event. You have to repaint your graphic items every time the form is redrawn, which happens quite frequently.

Hey,

Has anyone updated windows components via a setup.exe??

Here is what I'm trying to do in a setup.exe.. I need to make sure the version of .NET is 1.1 if not, update it, check to see if the directx is version 9.0c...if it's not update it...then install the original package (which requires .NET1.1 and directx 9.0c.

This way I don't have to have the user manually update the windows components in order to run the program I'm installing..

Any advice would be great!

Thanks,

Printed to CDs will be the primary deployment medium (maybe downloadable as well)

yes, .NET and the directx will be included (they both are redistributable.)

Printing Word Documents

I feel I need to share this pain. I have been struggling for days now to get something simple to work for me. That is to print out a Word document(rtf format) to a printer using Word. It also has to work with multiple versions of Word (so far 2000 and 2003). I thought I would share everything that I have learnt.

If you want this to work for multiple versions, install the earliest version of Word and Add Reference to it's COM component and develop against these.

Next to the code...

<br />
// Create an Application object<br />
Word.ApplicationClass ac = new Word.ApplicationClass();<br />
Word.Application app = ac.Application;<br />
<br />
// I'm setting all of the alerts to be off as I am trying to get<br />
// this to print in the background<br />
app.DisplayAlerts = Word.WdAlertLevel.wdAlertsNone;<br />
<br />
// Open the document to print...<br />
object filename = "myFile.rtf";<br />
object missingValue = Type.Type.Missing;<br />
<br />
// Using OpenOld so as to be compatible with other versions of<br />
// Word<br />
Word.Document document = app.Documents.OpenOld(ref filename,<br />
                    ref missingValue, ref missingValue, <br />
ref missingValue, ref missingValue, ref missingValue, ref missingValue, ref missingValue, ref missingValue, ref missingValue);<br />
<br />
// Set the active printer<br />
app.ActivePrinter = "My Printer Name";<br />
<br />
object myTrue = true; // Print in background<br />
object myFalse = false;<br />
<br />
// Using PrintOutOld to be version independant<br />
m_App.ActiveDocument.PrintOutOld(ref myTrue, <br />
                    ref myFalse, ref missingValue, ref missingValue, ref missingValue, missingValue, ref missingValue, <br />
ref missingValue, ref missingValue, ref missingValue, ref myFalse, ref missingValue, ref missingValue,    ref m_MissingValue);<br />
<br />
document.Close(ref missingValue, ref missingValue, ref missingValue);<br />
<br />
// Make sure all of the documents are gone from the queue<br />
while(m_App.BackgroundPrintingStatus > 0)<br />
{<br />
     System.Threading.Thread.Sleep(250);<br />
}<br />
<br />
app.Quitref missingValue, ref missingValue, ref missingValue);<br />

I do not claim that this is perfect, but it's as good as I can get. It works on my machine anyway

You might want to write up an article for this instead. Your post will be knocked off the first page of this forum in less than a day.

Cheers. I've just done that. I wasn't sure how useful somethign like this is and there is already some similar code on here, but it's awful to read. Plus I am hoping that people will point out any flaws in the code as I am pretty sure it doesn't work perfectly

How about making use of the StreamWriter[^] class.

The DEF[^] extension is in use by at least 18 different applications, according to the FileExt database.

Do you mean this?

	}
		
	public void PublicFunction()
	{
		//...
	}
}

public class Class2
{

This will work just fine, however I was thinking of doing it somehow without instantiating the object.

Then you will have to use the static keywork which permits you to use a class without instantiating it :

public class Class1
{
	public static void PublicFunction()
	{
		//...
	}
}

public class Class2
{
	public Class2()
	{
		Class1.PublicFunction();
	}
}

Something along these lines will do it

Netbios Messages sent before UDP packet

Will987654321015-Jul-05 4:05

Will9876543210

15-Jul-05 4:05

I am having problems using UDPClient.Send() in System.Net.Sockets. Each time
I make the call to the function, there is a significant delay from when the
code is executed to when the packet actually goes out. I took a look at the
traffic and found that each time the UDPClient.Send() call was made, two UDP
netbios messages go out on port 137. The device on the other end responds
each time with an ICMP. After two attempts, the .Send gives up, then
forwards the message.

The problem is, the huge delays in transmission are really throwing off my
timing. Why is the Send command tring to send out netbios messages? Can I
disable that? UDP is supposed to be connectionless. I just want to send
data with minimum delays!

You dont say which overload of Send you call. I suspect this one:

int Send(byte[] dgram, int bytes, string hostname, int port)

That method calls DNS.Resolve, and the likely reason for the 2 netbios messages. Use the IPEndPoint overload instead.
