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

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?
|

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 
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 
any suggestions welcome!
TIA
Pakl

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

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...

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

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.
|
|
|
|
|
No, a schema defines the order as well.

hmm, alright, probably I am not understanding that so well after all
how exactly would it help me, if I had a schema...
btw. thanks for your time

It wouldn't, directly, unless you needed to validate the documents coming in. But, it's very uncommon for a program to not care what order the nodes are in, or expect them to differ.

I have two objects that I'm drawing to the screen each is drawn in its own graphics context. I set region, clipping region, etc.. appropriately.
My question is this if I want to do a hit test, combine the two regions or whatever how do I/do I have to save the context and restore it and if so how????
I'm real confused???????
Thanks for any help

I am new to .net and C# programming and I am writing a POS type of application that prints a receipt to a small receipt printer. I am having some problems understanding how to format my report for this little printer. It will work in a laserjet on a full sheet, but it won't print on the receipt printer. This is making me crazy!!! Anyway if anyone has any ideas I am so in need of help.
Thanks!!!

hi,
for POS applications , normally APIs are available like OPOS. which provide methods for primitive printing tasks. for direct printing to a printing device using serial cable , u still can use OPOS standard. u will have to use special characters at begining and end of , for instance , a string to print it. in both cases, you will have to build a string that you want to print and send to printer (like a batch printing pattern). i dont think u its going to be like windows standard printing (i.e on A4 printer).
have a look here for more info

I'm need to have a control at my c# app that enables the user to crop a picture. I was looking for something like the way it is done when you use a scanner at windows XP(WIA).
Will I have to code it myself or is something allready done for that?
