Values containing more digits will be displayed in full on the left side of the decimal point and rounded on the right side. You can insert commas into large numbers by specifying a pattern that embeds a comma within a sequence of #s. For example, this:

1 = x2 < 0,

} // Overload Set. public void Set(double a, double b) { Console.Write("Inside Set(double, double). "); x = (int) a; y = (int) b; Show(); } public void Show() { Console.WriteLine("Values are x: {0}, y: {1}", x, y); } } class InvokeConsDemo { static void Main() { Type t = typeof(MyClass); int val; // Get constructor info.

Console.Write(" " + t.Name + "("); // Display parameters. ParameterInfo[] pi = c.GetParameters(); for(int i=0; i < pi.Length; i++) { Console.Write(pi[i].ParameterType.Name + " " + pi[i].Name); if(i+1 < pi.Length) Console.Write(", "); } Console.WriteLine(")"); } Console.WriteLine(); // Find matching constructor. int x; for(x=0; x < ci.Length; x++) { ParameterInfo[] pi = ci[x].GetParameters(); if(pi.Length == 2) break; } if(x == ci.Length) {

The key to troubleshooting network problems successfully is based on eliminating the unnecessary information and focusing on the critical information that is essential to solving the problem. Computer networks process thousands of frames per second. A protocol analyzer can quickly fill a 32 MB capture buffer with frames, and a user can sift through protocol decodes searching for the errors. But this is a time-consuming and tedious task. The most powerful function of protocol analysis is the ability to filter the data on the network in order to isolate problems. The function of a filter is very similar to that of a trigger, sometimes also called a trap. Specific filter patterns are set by the user of a protocol analyzer; these filters then are compared with the data from the network. Filters range from simple bit-pattern matching to sophisticated combinations of address and protocol characteristics. There are two fundamental types of filters, capture filters and display filters (Figure 24.9). Capture filters are used to either include or exclude data from being stored in an analyzer s capture buffer. Capture filters make it possible to collect only the frames of interest by eliminating extraneous frames. This effectively increases the usage of the capture buffer. Rather than a 32 MB capture buffer that contains only 6 errored frames out of 40,000 captured frames, the data is filtered so that only errored frames are in the buffer. More frames of interest can be captured and they can be located more quickly. A disadvantage of capture filters is that it is necessary for the user to know what to filter on, that is, to have some idea of what problem to investigate. A second disadvantage is that the frames that were filtered out might contain a sequence of events leading up to the errored frame. In many situations the source of a network problem is not known, so it is necessary to capture all the frames on the network and use display filters to repeatedly filter the frames. Because all of the frames are stored in the capture buffer, the frames can be played back through the display filters. Display filters act upon the frames
