i am working on a project to communicate with clinets using tcp/ip protocol.
I have a server system where this program is being done. I have clinets which are connnected to my ip. These clients are capable of accepting commands from the server and gove reply for that. For eg:- if i give %Name to clinet it will send back the system ip address.
private void button1_Click(object sender, EventArgs e)
{
Listener = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
IPEndPoint ipLocal = new IPEndPoint(IPAddress.Any,5005);
Listener.Bind(ipLocal);
Listener.BeginAccept(new AsyncCallback(OnClientConnect), null);
}
private void OnClientConnect(IAsyncResult asyn)
{
Client = Listener.EndAccept(asyn);
WaitForData();
}
private void WaitForData()
{
Client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(OnDataReceived), null);
}
private void OnDataReceived(IAsyncResult asyn)
{
Byte[] sendBytes = Encoding.UTF8.GetBytes("%Name");
string szData;
int iRx = 0 ;
iRx = Client.EndReceive(asyn);
char[] chars = new char[iRx + 1];
System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
int charLen = d.GetChars(buffer, 0, iRx, chars, 0);
szData = new string(chars);
MessageBox.Show(szData.ToString());
Client.Send(sendBytes);
WaitForData();
}
The sending of data is working fine here. but when i revceive data they are all junk values even after converting to string. Junk vlaues means some single characters only
Please let me know if tehre is someone extertise in this feild as i am new to this
Thanks in advance

I've used:
string receivedText = System.Text.Encoding.ASCII.GetString(buffer, 0, buffer.Count));
Of course this assumes that "buffer" in your case is a byte array.
Also, please be sure to check what the client is supposed to be sending. Is it an array of values that need interpreting? Or is it a human readable string?

I want to take very fast screenshots of my full screen with a timer. I hope this can be done with DirectX.
On this page[^] is an example of doing this in C++. But... the rest of my project is in C#, so I hope it also can be done in C#. I need the screenshot as a Bitmap variabele, it won't be saved as a file.
Hopefully, someone got a full sourcecode example, because I don't know much of DirectX.

A generic collection i.e. cCurves is populated with data.
The collection has several fields.
I am interested in two of the fields i.e. Name and Name2
As a test, the following return data from the collection.
cCurves[0].Name1
cCurves[0].Name2
cCurves[1].Name
cCurves[1].Name2
cCurves[2].Name
cCurves[2].Name2
...
How can I use a loop to populate a simple array with the
data (Name, Name1 fields for each row) in the above collection please?
Thanks
|
|
|
|
|
for(int i=0; i<numElements; i++)
{
cCurves[i].Name1 = whatever;
cCurves[i].Name2 = whateverelse;
}
|
|
|
|
|
Can you please simplify the code as it seems to have syntax error. thanks

Ah... That is because I forgot to HTML encode the < symbol
for(int i=0; i<numElements; i++)
{
cCurves[i].Name1 = whatever;
cCurves[i].Name2 = whateverelse;
}

Please note that I am trying to create and populate a simple array from an existing collection. I just realised that I think you are not doing that in your earlier code. Thanks
|
|
|
|

You can try using foreach loop over this collection.
|
|
|
|
|
doing this at present
for (int i = 0; i <= cCurve.Count; i++)
{
}
not sure how to declare and populate an array from this collection (cCurve)
|
|
|
|
|
Array curve = new Array(cCurve.Count);

if (ApplicationDeployment.IsNetworkDeployed)
{
ApplicationDeployment CurrentDeploy = ApplicationDeployment.CurrentDeployment;
if (CurrentDeploy.CheckForUpdate())
{
CurrentDeploy.Update();
DialogResult dr = MessageBox.Show("Update Downloaded,Restart the Application", "Application Update", MessageBoxButtons.YesNo);
if (dr == DialogResult.Yes)
{
Application.Restart();
}
}
}
else
{
MessageBox.Show("No Updates are available", "UpDate Info");
}
}
but it is working fine for some applications but for my application it is not working.
Please Help me on this(is there any other methods to fullfil my requirement)
Thanks in advance

Is there a "details" button that shows the error details? You should look at the stack trace and see where the error is occurring -- is it happening in your code?

I would guess your issue has to do with your Application.Restart and your ApplicationDeployment object. The methods you are using assume that you are using clickOnce deployment. I am guessing that you are trying to update your application outside of ClickOnce. If you are there is a good chance that you have missed some settings. Things like the UpdateLocation. If you are using click once, then you don't have to write this code your self it will just get the latest version automatically.
Hope that helps.
