I’m trying to build a solution for my FEZ Cobra and I’m getting the following error message:
------ Build started: Project: FEZ Cobra METAR Test, Configuration: Debug Any CPU ------
MMP : error MMP0000: CLR_E_FAIL
========== Build: 0 succeeded or up-to-date, 1 failed, 0 skipped ==========
This one’s pretty cryptic … I had no luck searching for information on the forum. Does anyone know what this means?
Not enough information 
Can you start new project and show us the code you add to give such error
OK, Gus …
Here is the “main” part of the code … it’s really simple and, in fact, it doesn’t even call any of the code in the other file yet.
using System;
using System.Threading;
using System.Net;
using System.IO;
using System.Text;
using System.Xml;
using Microsoft.SPOT;
using NetInfo = Microsoft.SPOT.Net.NetworkInformation;
using METAR;
namespace FEZ_Cobra_Console_Application1
{
public class Program
{
public static void Main()
{
// Set up networking ...
NetInfo.NetworkInterface NI = NetInfo.NetworkInterface.GetAllNetworkInterfaces()[0];
NI.EnableDhcp();
Debug.Print("\n\rDCHP - IP Address = " + NI.IPAddress + ", Net Mask = " + NI.SubnetMask + ", Gateway = " + NI.GatewayAddress);
Debug.Print("DNS Server = " + NI.DnsAddresses[0].ToString() + ", MAC Address = " + NI.PhysicalAddress[0].ToString() + "-" + NI.PhysicalAddress[1].ToString() + "-" + NI.PhysicalAddress[2].ToString() + "-"
+ NI.PhysicalAddress[3].ToString() + "-" + NI.PhysicalAddress[4].ToString() + "-" + NI.PhysicalAddress[5].ToString() + "\n\r");
}
}
}
The other part of the code is shown below -

while (!xmlr.EOF)

try

}
catch (Exception e)
{
Debug.Print("xml.Read() Exception: " + e.ToString());
break;
}
if (xmlr.NodeType == XmlNodeType.Element) // We found a potential tag ...
{
foreach (string tag in tags) // so loop through the strings in the "tags" array ...
{ // and compare the potential tag to the tags we are looking for.
if (xmlr.Name == tag) // If we find a match ...
{
foundTag[k, 0] = xmlr.Name; // save the tag, ...
xmlr.Read(); // do another read to fetch the value associated with the tag, ...
foundTag[k, 1] = xmlr.Value; // and save the value
k++;
} // End if
} // End foreach
} // End if
} // End while
response.Close();
return foundTag;
} // End getWeather
//
//
public string[,] getObs(string icao)
{
int tries = 0;
string[,] obs = new string[tags.Length, 2];
//
while (tries < maxRetries)
{
obs = getWeather(icao);
if (obs[0, 0] != null)
return obs;
tries++;
Thread.Sleep(retryWait);
} // End while
return obs;
} // End getObs
} // End class getMetar
} // End namespace METAR
When I can get the whole thing to build, I’ll add a call to “getObs” to main. 
I tested the code from the METAR namespace in .NET on a PC, and it worked just fine. Thanks for taking a look at this …
multi-dimensional arrays are not supported in NETMF. You can use jagged arrays instead.
int [,] //no good
int [][]//this is okay
Thanks Gus … that solved the problem. :-[
Chris - Yes, I know … but it’s more fun for me if I re-invent the wheel. ;D I learn more that way.
