I expect 10 ReadByte() to take longer than a single Read() reading 100 bytes.
2.
Invalidate() and Refresh() don't belong inside a Paint handler; a Paint handler should paint, be swift and not cause other things to happen.

use onPaint event and it will solve your problem.

Hallo, I am looking for a tiny but great programm which merges pdf files. I used it some years ago for joining over 1000 of small pdf files into a big one. Unfortunately, I do not remember its name, but I remember it was written in C# and the source code was given as well. I cannot find it, nor any that great to do my job with many pdf files. Upon running it promted the user to make a few decisions using a simple GUI, almost a Message Box. I would very much apprexiate any help. Thanks.

Not sure about the source code thing, but PDF metamorphosis is written in C#. Check if that is what you are looking for.

Good luck

This is what I have done to identify the vehicles from a given picture using Emgu CV (StructuringElementEx). Now I want to get the count of these identified vehicles.
If anyone know how to do that, it is a great help to me.
Thank You.

I have a project that integrates RichTextBox tips from many articles across the web. Everything from XP Style borders, to WYSIWYG printing.
One thing missing is rendering of page breaks.
I can insert an RTF page break that is visible when loading the resulting rtf file into Word, or similar. However I can't find how to render it inside the RichTextBox.
I would like to render a nice dotted line at that point.
So far my searches have only turned up print rendering articles, which I already have.
Any suggestions or links to appropriate aticles would be welcome.

This is what I know about the matter, mostly from reading the RTF specification and from experimenting (I did quite some work on tables, perfectly readable in WordPad):
- there are hundreds of RTF commands;
- Word can create RTF documents, and will use a lot of the existing commands;
- WordPad can create RTF documents, and will use only few of the existing commands;
- WordPad can show a lot of RTF stuff it does not let you create interactively;
- RichTextBox shows RTF documents pretty much the same as WordPad does.
- RTF has a \page command
- WordPad shows it as an empty line
From that I would conclude:
- by default RTB hardly renders a page command
- you can of course add whatever text and formatting code you like whenever you also insert a page command; that is after all what Word does when it creates headers and footers for you.

Thanks Luc
I am using the \page command and it works fine when printing or loading into Word, just no visual cue in the RichTextBox. I hadn't realised WordPad did nothing to indicate the page break. If Microsoft left it out of WordPad I don't feel so bad about not implementing it myself.
I guess the simplest solution will be for me to insert a horizontal line in place of any page breaks and replace them with real page breaks on save.

You're welcome.

That sounds OK. Whatever you want to achieve, it probably can be done, but you'll have to manipulate the RTF string yourself.
FYI: as always, the document Word generates is overly complex; WordPad does a much better job, assuming it allows you to enter what you need. When working with tables, I looked at what Word does, read the RTF specs, and created it all in code, I didn't want hundreds of lines of initialization (and it gets worse in every new Office version).

The structure of my listview is:
Select ID Name Age
--------------------------------------------------
Item[0]: checkbox 25 Richard 24
Item[1]: checkbox 26 Tom 20
Item[2]: checkbox 27 Alice 22
......many.....
Now, I want to get the name or age of current item when I make the item checked or unchecked. In other words, when I click a checkbox, I need to know the index of the item. If there is only one checked item, we can use "foreach" to get the index, but there are some already checked items.For example:
Item[0] and Item[1] are checked.
I click the checkbox of Item[2], How can I know what I clicked is Item[2]? (Here is not related to SelectedItem.)
Excuse me,My English is poor.

You need to handle the ItemCheck event of your ListView.
The event handler skeleton inserted for you by the IDE has an ItemCheckEventArgs which contains, amongst other things, the index of the checked item and its current state (checked/unchecked). You can use this information to decide what to do.

I can't have my cocoa until the nurse has bought me my tablets and she's late.

I'm afraid she broke down, after having to bring you truck loads of beer, coffee and cigarettes all day long. Besides, the local pharmacies have long closed, and you shouldn't expect her to travel all the way to the other side of Wolverhampton, just to buy you some tablets. I suggest you have some more After Eights and call it a day. You can catch up on tablets on Monday.

hi, I'm using below code for a basic client/server communication. I send a string to server and server sends it back to client with no problem. But I can do this only once and then connection goes, what should I do to be able to send more strings one after other without loosing the connection? Thanks in advance
/// Server Code:
private void button1_Click(object sender, EventArgs e)
{
TcpListener tcpListen = new TcpListener(IPAddress.Parse("192.168.1.6"), 1234);
tcpListen.Start();
Socket socket = tcpListen.AcceptSocket();
if (socket.Connected)
{
while (true)
{
NetworkStream stream = new NetworkStream(socket);
StreamReader streamRead = new StreamReader(stream);
StreamWriter streamWrite = new StreamWriter(stream);
try
{
streamWrite.WriteLine("Incoming message: " + streamRead.ReadLine());
streamWrite.Flush();
}
catch (Exception)
{
label1.Text = "Server is being shutdown";
return;
}
}
}
socket.Close();
}
/// Client Code:
public TcpClient client;
NetworkStream stream;
StreamReader streamRead;
StreamWriter streamWrite;
private void button1_Click(object sender, EventArgs e)
{
try
{
client = new TcpClient("192.168.1.6", 1234);
}
catch (Exception)
{
MessageBox.Show("Not Connected");
}
stream = client.GetStream();
streamRead = new StreamReader(stream);
streamWrite = new StreamWriter(stream);
try
{
streamWrite.WriteLine(textBox1.Text);
streamWrite.Flush();
string line = streamRead.ReadLine();
MessageBox.Show("Message from server: " + line);
}
catch (Exception)
{
MessageBox.Show("Connection error");
}
streamWrite.Close();
streamRead.Close();
stream.Close();
}

Dah, How about not closing the socket.
Of course, the connection is lost each time, you told it to do that. Create the connection outside of the button click event and don't close it until necessary.
