Hi All
I am creating an application which takes some SQL code into a rich text box, with Syntax highlighting. I have inherited the Rich Text Box and put my word recognition code in here. The problem I have is that when ever the syntax highlighting code runs, the whole rich text box flickers annoyingly.
Does anybody know how to stop this flickering?
Thanks in advance. 
oooo, the Jedi's will feel this one....

I'm sorry i wasn't sure if the question was to be posted in C# section or Java section.
|
|
|
|
|
since the code you will be writing is Java the Java forum is the right one

On top of Tom's answer, it doesn't mater in this instance too much which you had chosen to start with. But you should have posted only once.

Hi,
I have this problem with C# socket server that's talking to a perl client. When I run the server and run the perl client with "perl client.pl commandtoexecute" the server executes the command displaying it on the server console and then crashes with this error:
Unhandled Exception: System.IO.IOException: Unable to read data from the transpo
rt connection: An existing connection was forcibly closed by the remote host. --
-> System.Net.Sockets.SocketException: An existing connection was forcibly close
d by the remote host
at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size,
SocketFlags socketFlags)
at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 s
ize)
--- End of inner exception stack trace ---
I know I am not handling the error correctly, but I have no idea how do I go about fixing this. Any ideas? here is the code for the method that is handling the client connections:
public void HandleConnection()
{
int recv;
byte[] data = new byte[2048000];
TcpClient client = threadListener.AcceptTcpClient();
NetworkStream ns = client.GetStream();
connections++;
Console.WriteLine("New client accepted: {0} active connections", connections);
string welcome = "Welcome to power shell server ... ";
data = Encoding.ASCII.GetBytes(welcome);
ns.Write(data, 0, data.Length);
while (true)
{
data = new byte[2048000];
recv = ns.Read(data, 0, data.Length);
if (recv == 0)
break;
else
{
String cmd = Encoding.ASCII.GetString(data, 0, recv);
Console.WriteLine(cmd);
//Console.WriteLine(Encoding.ASCII.GetString(data, 0, recv));
//ns.Write(Encoding.UTF8.GetBytes(RunShell(cmd)), Convert.ToString((RunShell(cmd))).Length, 10000000);
// Execute incoming shell command and convert the string data to byte data using ASCII encoding.
byte[] byteData = Encoding.ASCII.GetBytes(RunShell(cmd));
// Begin sending the data to the remote device.
if (byteData.Length > 0)
ns.Write(byteData, 0, byteData.Length);
else
{
Console.Write("\nData Length is less than 0");
ns.Write(data, 0, recv);
}
}
}
ns.Close();
client.Close();
connections--;
Console.WriteLine("Client disconnected: {0} active connections", connections);
}
|
|
|
|
|
Probably you get the exception in this line:
recv = ns.Read(data, 0, data.Length);
If yes, then the remote host just disconnect you.
|
|
|
|
|
Thanks for the reply. Actually the server is crashing at:
ns.Write(byteData, 0, byteData.Length);
Because after this is executed, the client has received the data and it closes the connection - I don't know if I have to catch an exception here? I am not good with exceptions. Also, I am closing the network stream here with ns.Close() and the server is still crashing. I am confused.

Hi,
I have string "[Font: Name=Microsoft Sans Serif, Size=20, Units=3, GdiCharSet=1, GdiVerticalFont=False]",
how can i convert it as Font or how to assign this to a Font.
Thankyou
YPKI

|
|
you need to parse it using string.split and then check the NVP and assign them to a font class
|
|
|
|
|
try FontConverter class. It may help you
|
|
|
|
|
Sorry, but this string can not converted to font!
I use split function instead!
and :
Font F=new Font(params)

Hi All,
I have browse button to select a .hex file, this file name should always have 3 underscores and .hex as extention (for eg. TestHex_1_1_1.hex). I had written a code by using split & it works. But if foldername contains any underscore then it will not work.
This is my code.
private void btnOpenFolder1_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
openFileDialog1.ValidateNames = true;
textBox1.Text = openFileDialog1.FileName;
char[] cr ={ '_' };
string[] str = textBox1.Text.Split(cr);
if (str.Length != 4 || textBox1.Text.Substring(textBox1.Text.LastIndexOf("."), 4).ToLower() != ".hex")
{
textBox1.Text = "";
MessageBox.Show("File name or file extention is not valid.");
}
hexPath = textBox1.Text;
}
Please give me any suggestion.

Check out System.IO.Path which has methods for getting extention from a path as well as filename from a path.

Hello.
I'm Reading data from an excel (CSV) file with header row and its fine.
Now I have a file with one more line in the start (above the header) and it giving me a lot of problems.
is there a way from C# to open the csv file and remove the first line?
If not as excel then maybe I'll just open it as a text file and remove it (I know whats the string I want to remove).
Whats the fasted way to remove a string from the beggining of a txt file?
Thanks.

Easy. File.ReadAllLines, to get an array of strings, then write the file over itself, skipping the lines you don't want anymore

Or better, write it into a new file, so it doesn't mess up Excel and other users?

I can't do that since I need to countinu working on the same file with others.
Taht another thinh I was afried of, that if I'll read and write it will mass up my original file 
Thats why I hoped that C# will have a built in function for this.
Thanks for your reply.

Hi christian,
Thakns for the replay.
I was hopping that C# have a built in function to work with excel and do this instead of me having to read a file with a lot of data (about 7,000 line with 10 column each).
But like I was afried, I might have no other choise other that read the whole file and write it back.
Thanks.

You will have to rewrite the whole file if you want to change it's contents. You should find quite a few samples through Google (e.g. http://stackoverflow.com/questions/532217/efficient-way-to-delete-a-line-from-a-text-file-c[^]).
Regarding CSV: There's a few frameworks flying around that provide you with an abstract view of a CSV file (there's even a LINQ implementation here on CodeProject). And of course, just retaining the file and ignoring the line in question might be an alternative, too. However, the added functionality most likely comes with a price regarding performance.

Hello all,
Thanks for the replies.
As you mantioned - I can not realy delete the first line so what I did at the end was to read the file (file.readAllLines(), As I saw in the answers) and then create it again after discarding the first line.
Not very elegant but work
Thanks again!
roy.
