to save what i add at the datagridview using form1 and load it in form2...please help

you must add the following functionality: ·  Save the information to a file ·  Load the information from a file ·  Draw several graphs to illustrate some statistics Each month a new file must be created to store the information of that month. The information must be stored in the following format: Date, Activity, Total_Time
Note: Total_Time is the total time for that day only! When loading data remember that only on day's data can be displayed at a time. However data from multiple dates are required for the statistics. You will need to create a means for the user to clear the grid. The following statistical data needs to be calculated and displayed in the indicated chart format: ·  The amount hours spent on a all activities on a specific day, as a pie chart ·  The average amount of time spent in a specific week on each activity, as a bar chart ·  The total time per week for each activity over a 4 week period, as a line (or XY scatter) chart.
