This control (with such an original name as DBnetPing 1.1!) has been designed to wrap the functionality of building an ICMP ping packet, sending it, and timing the response to give you an accurate ping time in milliseconds.
Simply drop the control onto your form and call the function:
results = dBnetPing1.pingHost(txtHost.Text);
results is a simple class that lets you call
GetResponseTimeMS which returns an
int containing (yep - you guessed it) the response time in milliseconds:
MessageBox.Show("Ping successfull! " + results.GetResponseTimeMS().ToString() +
" ms", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
I created this function/wrapper heavily based on already existing C# code; unfortunately, I do not remember the author. If anyone can help me here, I'd be glad to add. Kudos.
