[RESOLVED] C# Unable to Show Socket Data In textbox

[-RaJ-]

I am having problem to show the Data arrived from System.Net.Sockets onto textbox

'Cross-thread operation not valid: Control 'txtDataRx' accessed from a thread other than the thread it was created on'

public void ReceiveSckData(IAsyncResult aData)
        {
            try
            {
                CSocketPacket theSockId = (CSocketPacket)aData.AsyncState;
                //end receive...
                int iRx = 0;
                iRx = theSockId.thisSocket.EndReceive(aData);
                char[] chars = new char[iRx + 1];
                System.Text.Decoder d = System.Text.Encoding.UTF8.GetDecoder();
                int charLen = d.GetChars(theSockId.dataBuffer, 0, iRx, chars, 0);
                System.String szData = new System.String(chars);
                //MessageBox.Show(theSockId.dataBuffer.Length.ToString());
                MessageBox.Show(szData);
                txtDataRx.Text = szData; // I AM GETTING ERROR HERE

                
                
                
            }
            catch (ObjectDisposedException)
            {
                System.Diagnostics.Debugger.Log(0, "1", "\nOnDataReceived: Socket has been closed\n");
            }
            catch (SocketException se)
            {
                MessageBox.Show(se.Message);
            }
        }

This is the VB.NET forum. C# questions belong in the C# forum. If you feel that your question is not language-specific then post in the .NET Architecture & Design forum. The only reason that C# code should be being posted in the VB.NET forum is if you are having trouble converting it to VB.NET.

With regards to the question, follow the CodeBank link in my signature and check out my post on Access Controls From Worker Threads. The SerialPort class raises its events asynchronously, i.e. on thread pool threads.

You originally posted this question in the VB.NET forum. I answered it there 2 hours and 36 minutes before you posted it here. You first posted a C# question in the VB.NET forum, then you ignored an answer when it was provided, then you posted the same question a second time. Please post each question once and once only, in the most appropriate forum for the topic. If you post in the wrong forum then don't double post; ask the mods to move the thread.
