JonnyBoats, Thanks for the insight. So I guess reading the moisture content of something physical is slightly more of a challenge than originally thought. And that's because i can't find a sensor that will do that for me... But really isn't it the same idea as a pentiometer? One prong receiving electricity, another for it to exit, and one in the middle to read what's moving across the other two?

Hi, I'd like to take readings of the ground's moisture content. What type of sensor would work best for this application? Does the sensor need to be buried or is there a better way to go about this? Thanks in advance! -blubblub

Fabien, Thanks for the feedback.

Hello,
So I think that I’m a little over my head here. I bought the Sparkfun RGB LED Matrix controller. It requires a 5V power supply which can be provided from the netduino plus but the SPI interface description states that it requires 5V on it CS pin for “high”. The max ouput on the netduino i/o pins is 3.3V right? What’s the best way to interface with this controller? Did I mention I’m a newb
Thanks in advance!

Can anyone show a simple working example of the XmlReader reading an attribute from an element? Otherwise I’ll move on to using strings instead. I don’t mind that the features aren’t available. The struggle is the limited resources in finding out if they are. Does a guiding rule exist when working with Netduinos (or other Micro Controllers) that could help determine if specific Assemblies, namespaces, classes and functions will not functioning as expected? Coming from a Web Dev. background I’m finding that I’m wrestling with the limited features of the micro framework. I like the refined and fresh approach of tackling the issues but I feel like I’m finding dead ends at every turn. I’m sure it’s just the learning curve but any help is appreciated. That’s why I like the forums. So, if anyone could answer the two questions above, Thanks in advance!

Thanks for the good feedback. Though I still don't seem to be able to get this to work for me. With the code below I'm receiving this error when I hit the XmlReader. Any ideas?

The system.xml class does not appear to have any options that can return attributes of an xml element. If no options exist, what's the alternative?

Hello, I'm trying to find a way to read/grab attributes from xml. Is the XmlReader class from the System.Xml namespace available? If not, does an alternative exist?

Oz, I tried "the quick fix" but received an IndexOutOfRangeException. In the end what Chris said about chunking the data works for this project. After the code below creates string chunks I'll trim the ends and make them xml. I should be able to grab the attributes I'm looking for from each element. The JSON idea makes sense but I'm working on xml files purposed for something else. I'm open to suggestions. I want to learn! That was a great first lesson. Thanks again!

FileStream fs = new FileStream("\\SD\\test.xml", FileMode.Open, FileAccess.Read);

            int nBits = 512;
            byte[] ByteArray = new byte[nBits];
            int nBytesRead = fs.Read(ByteArray, 0, nBits);
            string strLine = "";
            char[] CharArray = Encoding.UTF8.GetChars(ByteArray);
            foreach (char i in CharArray)
            {
                strLine = strLine + i;
            }

            Debug.Print(strLine);

Hello,
I'm trying to load an xml file residing on the SD Card. The original file is 82kb in size and will not load. But if I reduce the file's size to 1kb it works. The error "CLR_E_OUT_OF_MEMORY" occurs when attempting to load the 82kb file. Does a limitation exist that I'm not aware of? Thanks in advance!!! My code below:

using (StreamReader r = new StreamReader("\\SD\\test.xml"))
                {
                    if (r.BaseStream.Length > 0)
                    {
                        do
                        {
                            
                            string line = r.ReadToEnd();
                            Debug.Print(line);
                            r.Close();


                        } while (!r.EndOfStream);
                    }
       
                }
