Getting an embedded resource

DanFraser · 10-15-2006, 04:34 AM

I'm stuck on this one...

I've figured out how to get an embedded picture file to be referenced (and that successfully shows a pic in a control, depending on another item being clicked). That works fine, got loads of pics sorted. What I can't figure out is how to read an embedded text file, process it, and throw the data in to an array.

Code:

public ResourceManager pics128Ships = new ResourceManager("POS_and_Fuel_Calculator.128shipPics", Assembly.GetExecutingAssembly());
        public ResourceManager pics128Pos = new ResourceManager("POS_and_Fuel_Calculator.128posPics", Assembly.GetExecutingAssembly());
        public ResourceManager pics256Pos = new ResourceManager("POS_and_Fuel_Calculator.256Pics", Assembly.GetExecutingAssembly());
        public ResourceManager DataPOSShips = new ResourceManager("POS_and_Fuel_Calculator.POSandShipsData", Assembly.GetExecutingAssembly());

the first three are pictures, no problems with those, so I should expect to do the same with the last one, which calls the *.resx file that has the information about the text files.

However, I'm not sure if I should be using the streamreader method to read through the text files, as building the program is fine, but running/debugging it produces -

Code:

The error originates from the first line here - (which is pretty much the first line of code in the whole program)

Code:

StreamReader sr = new StreamReader(DataPOSShips.GetString("Ships.db"));
            //StreamReader sr = new StreamReader(@"K:\Programming Projects\POS and Fuel Calculator\POS and Fuel Calculator\POS.db");  //the old way of calling a file (it worked...)
            StringBuilder sb = new StringBuilder("");
            int stringCounter = 0;
            while (fuelSize != -1)
            {
                char char1 = (char)sr.Read();
                string string1 = char1.ToString();
                if (string1 == "#")
                {
                    shipsList[stringCounter] += sb.ToString(0, sb.Length);
                    break;
                }
                if (string1 == "@")
                {
                    shipsList[stringCounter] += sb.ToString(0, sb.Length);
                    sb.Remove(0, sb.Length);
                    stringCounter++;
                }
                else
                {
                    sb.Append(string1);
                }
            }

What should I be doing to read in this damn text file??

Code:

StringReader sr = new StringReader(DataPOSShips.GetString("Ships"));

That's how...
