There are multiple tutorials and introductions to .NET and C# online. Google the .NET area you want to learn about..
Regarding books, I find "Programming C#" by Jesse Liberty from O'Reilly to be pretty good.

Hi.
I've used a WebBrowser to print a HTML file , I want to omit footer[^] and header[^] of the Print result.
Could you guide me how I can do it ?
|
|
|
|
|
Construct a version of the page with these elements and use it for the print
only two letters away from being an asset
|
|
|
|
|
Thanks, I couldn't understand well, could you please describe it more ?
|
|
|
|
|
What don't you understand about having a version of the page you are rendering without the header and footer elements?
Alternatively, use the CSS media type to control what is available for printing

Hey guys
I'm having some troubles communicating to an external device over the network.
Here's my code
TcpClient BadgerConnection = new TcpClient();
BadgerConnection.Connect(IPAddress.Parse("10.0.0.100"), 1111);
if (BadgerConnection.Connected)
{
StreamWriter sw = new StreamWriter(BadgerConnection.GetStream());
sw.AutoFlush = true;
char[] Buffer = new char[]
{
(char)161,
(char)15,
(char)89,
(char)1,
(char)89,
(char)3,
(char)102
};
sw.Write(Buffer);
}
So obviously this isn't working, cause if it did I wouldn't be here
What I did was get a packet sniffer and attached it to my program before connecting to the external device.
Here was the result in hex:
C2 A1 0F 59 01 59 03 66
Here's what I intended to send in hex:
A1 0F 59 01 59 03 66
There's an extra character showing up... C2 or rather 194.
Can someone please explain to me why and how can I stop it from sending the extra character?
Thanks

Odd, I would have expected an UTF-8 BOM, but C2.. that's something else..
Anyway, why are you using chars at all? Why not just bytes?
If you send them as bytes, that should probably get rid of that C2 (at least I never noticed extraneous C2's while sending plain bytes)
|
|
|
|

I tried sending just bytes bytes like so
TcpClient BadgerConnection = new TcpClient();
BadgerConnection.Connect(IPAddress.Parse("10.0.0.100"), 1111);
if (BadgerConnection.Connected)
{
StreamWriter sw = new StreamWriter(BadgerConnection.GetStream());
sw.AutoFlush = true;
byte[] Buffer = new byte[]
{
161,
15,
89,
1,
89,
3,
102
};
sw.Write(Buffer);
}
And the sniffer picked up this:
00000000: (TCP/IP) Sending Packet, 17.09.2009 15:24:37.684
BadgerTest.vshost.exe (2188)
0.0.0.0:1200 ® 10.0.0.100:1111
Size: 13 bytes
53 79 73 74 65 6D 2E 42 79 74 65 5B 5D System.Byte[]

It seems to be the StreamWriter 's fault, what if you send them "normally"?
eg
TcpClient BadgerConnection = new TcpClient();
BadgerConnection.Connect(IPAddress.Parse("10.0.0.100"), 1111);
if (BadgerConnection.Connected)
{
byte[] Buffer = new byte[]
{
161,
15,
89,
1,
89,
3,
102
};
NetworkStream ns = BadgerConnection.GetStream();
ns.Write(Buffer, 0, Buffer.Length);
ns.Flush();
}

That worked like a charm... BUT only the first time
If I try to send that same set of bytes a second time i get an exception
Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host.
Any ideas?

Well, if it were making sense it might mean that the other side did a Close on their Socket
But with networks, sense rarely comes into play
What kind of thing is the remote host? Does it close its socket after any command?

Nope, it doesn't

Hi people
I'm building a desktop application and I want to include a Hyperlink somewhere on my form. This link should not link to a website though, it should instead call a method. Is this possible?

Use the Click event of a label, linkLabel or any control you think is appropriate.

hi all
i have two project and they are almost the same each other
in one of them i have obj\release file
but in another i dont have
i want to have it in another one also
so how i can make it ??
i will be happy if u help me
|
|
|
|
|
I was under the impression that the \obj folder was only used for temp files. You should use the assembly's in the \bin folder.
|
|
|
|
|
i am tryin to make that proect's exe file
and at the end of the command line i have such a line
/resource:obj\Release\PanelDenemem.Form1.resources
when i write that code to command prompt it gives error
because i dont have release file under object file
but i have debug file there
so what is wrong ??
|
|
|
|
|
It would appear that you have not built the release version of the project. Did you check that obj\Release\PanelDenemem.Form1.resources actually exists?

Hello
Is there anyone out there that knows how to develop the connection points that indicate relational mappings between two objects.. example: C# dataset designer can indicate foreign key relationships, or MSSQL diagrams also have the same connecting points that are adjustable. Adjustable by means of it not always being a straight line at all times..
So i'm building a busines object modeller and require the ability to show relational connection points on my business objects on a designer canvas. This leads my to believe that a implentation of maybe IDesignerHost is valid, but i would not know where to start with those connecter objects..
anyone.. please help.
Regards
