System.IO.File.Exists - something like that. If it doesn't exist, create it.

Regarding focus setting on a drop down in C#!

16-Jan-07 23:52

Well, which bit is confusing you ? I can't tell you how to create the file, I don't know why you're creating it, or what you want to put in it.

UDP send file issue

I try to use UDPClient to send a file
but when i send a small file like 50k, the UDPClient works good
but when i send a file 500k
the UDPClient.Send() throw an exception

A message sent on a datagram socket was larger than the internal message buffer or some other network limit, or the buffer used to receive a datagram into was smaller than the datagram itself

Someone can help me to fix this issue, it looks like the send buffer and receive buffer are to small.

I want to make some friends here

Hi All,
In my page,am using a dropdown. After selecting the drop down the page is getting postback. After the postback is done, the focus on that control is getting lost. I want the focus to be set on the Item which I have selected earlier(before postback)..
Thanks in Advance...

Thanks,
Mirunab

Reverse Engineer / view C# / .NET code?

16-Jan-07 19:28

Why do all the ASP.NEt questions end up here ?

If you want the control selected, your best bet would be to avoid auto postback. Otherwise, you need to programattically set focus to the control in your event handler that is being called anyhow. Not sure if there's a property in C#, or if you need to write some jscript.

I have a .NET exe that I don't have the code for. Is there a way to reverse engineer it, and look at the code?

Sure, just google for reflector, and download it.

I'm not sure what a lot of this means, but Mono is the Linux port of C#.

You need Mono. See the articles on this site and this link:

well mono is the only chance of c# on linux, but as I said "chance"..
mono isn't the framework. it's less functional and if memory didn't trick me it's only framework 1.1 'compatiblie'

life is study!!!

I thought Microsoft was supposed to be working on Linux support. I found this for FreeBSD: http://msdn.microsoft.com/msdnmag/issues/02/07/SharedSourceCLI/

thx for the information
I though that the c# compiler wasn't open source so how did they get it on linux? So c# on windows is not really the same as on linux?

Reading Xml using XmlReader

Not that I completely understand it, but what I think they are doing with this project is creating a Common Language Runtime library for FreeBSD. So in theory your compiled c# code should run on FreeBSD with Rotor installed.

FreeBSD is not Linux but it is a free version of Unix that is similar to Linux.

Hi folks,

I am a bit puzzled how to use the System.Xml.XmlReader to read data D'Oh! | :doh:

To give a simple example I want to read a Xml file like this:

<Person>
<Name>Peter</Name>
<Sirname>Alen</Sirname>
</Person>

in a object with the same properties...

what I did was something like this:

...
Person person = new Person();
while (reader.Read())
{
if (reader.Name=="Name")
{
person.Name = reader.ReadElementContentAsString();
}
if (reader.Sirname == "Sirname")
{
person.Sirname = reader.ReadElementContentAsString();
}
}
...

of course simplified, the real thing is a bit more complicated...
this does work if the Xml is exactly the same way I outlined above but if, for example, the Name tag comes after the Sirname tag the code doesn't work anymore because the reader.ReadElementContentAsString() is advancing the reader and the reader.Read() as well thus one element is simply not handled by the code in the while loop...

I hope I explained it well enough Sniff | :^)

any suggestions welcome!
TIA
Pakl

If you don't have a proper schema, you're better off using an XmlDocument or XmlDataDocument, and XPath

Patrick Klug16-Jan-07 14:49

16-Jan-07 14:49

hmm, alright...

then I will switch to XPath for reading and use XmlWriter for writing...

thanks

just another thought...
I searched for any trick I could use to keep using XmlReader... maybe something like this...

bool read = false;
do
{
	read = false;
	if (reader.Name=="Person")
	{
		person = reader.ReadElementContentAsString();
		read = true;
	}
..... other stuff comes here...
}
while (read || reader.Read())

but of course I don't want to create a mess when I forget to set the read = true....
doesn't seem to fit so I will use XPath...

Christian Graus16-Jan-07 14:57

The core issue is that you don't have a defined schema. It would be better if you did.

Patrick Klug16-Jan-07 15:15

16-Jan-07 15:15

I understand. Just a question on that topic.

If I have a defined schema, does this mean that those tags have to be in the same order all the time.
I always thought that it is 'correct' to place tags in any order in the file.

Christian Graus16-Jan-07 16:32

16-Jan-07 16:32

No, a schema defines the order as well.
