Set the MultiLine property of TextBox to True as given here
http://msdn.microsoft.com/en-us/library/12w624ff.aspx[^]
for showing and editing multiple lines. Then the following code can be used to read all the text from the inputFile to the TextBox and then to save the modified text from the TextBox to the outputFile
TextBox1.Text = System.IO.File.ReadAllText(inputFileName);
System.IO.File.WriteAllLines(outputFileName, TextBox1.Text);

You need StreamReader to read the data from file and show into text box, Here is the code snippet for that:
sr = new StreamReader(filename);
while (!sr.EndOfStream)
{
if (txtBox.Text.Trim() == "")
{
txtBox.Text = sr.ReadLine();
}
else
{
txtBox.Text = txtBox.Text + Environment.NewLine + sr.ReadLine();
}
}
Note: TextBox Should be Multiline, replace the "filename" with your file location and you must include:
using System.IO;
Now for saving the data, you need to write the text of textbox in file. For that ou need StreamWriter. For this You can take the reference from following link:

Hi all
I am having a picture box with a world map image of size 1800*3600 in it. Now I would like to create heat maps at different points based on latitude and longitude positions and the intensity of heat maps should be different for each point.
can anyone help me in designing the above said feature
thanks

The key point is, I think, to map or translate the GPS coordinates with the XY coordinates of your image.
image top left = XY (0,0) and corresponds to GPS (?, ?)
bottom right = XY (3600, 1800) and corresponds to GPS (?, ?) (assume x=3600 and y=1800)
(and everything in between).
You might want to opt to move the base (XY 0,0) with the GPS 0,0.
Hope this helps.
V.
