    <p>I'm having troubles with UdpClient in C#. I am streaming audio over the internet between two clients.</p> <p>On my microphone, with a sample rate of 16khz, I send UDP packets with audio with 6400 byte per packet. These never get through, except the last packet which is usally around 1200-3400 something since I close the recording. When I lower sample rate to 8khz, I send packets with 3200 byte payload. These always get through for some reason. </p> <p>So basically anything above 3200 gets botched (havn't tested an exact number but...) why on earth is this? I was thinking perhaps the UdpClient internal buffer is too small or something? Since I stream audio packets gets sent frequently. </p> <p>RECEIVE:</p> <pre><code>private void audioReceive(IAsyncResult asyn) { try { byte[] temp = audioSock.EndReceive(asyn, ref this.serverEP); this.waveProvider.AddSamples(temp, 0, temp.Length); this.textbox_display.Text = this.textbox_display.Text + " got bytes: " + temp.Length; audioSock.BeginReceive(new AsyncCallback(audioReceive), null); } catch (Exception ez) { MessageBox.Show("audioReceive: " + this.textbox_nick.Text + " " +ez.ToString()); } } </code></pre> <p>I can't find any obvious fault. (The asyn object to the function is null btw, I do not need to use a stateobject , but that shouldn't be related to this)</p> <p>I know UDP is not reliable, but considering every single 3200 sized packet get through and no 6400 size smells fishy to me, especially with max size is what, 64kb?</p> <p>Any ideas?</p>

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
