Hi,

I have been trying for two days now to get this bit of code to work, in many different ways.
I basically need a 2d array, which asks via the visualbasic inputbox for 5days and 4 weeks worth of values (numbers) and puts them into the array.

C#

int[,] toys = new int[5, 4];
            for (int week = 0; week <= 3; week++)
            {
                for (int day = 0; day <= 4; day++)
                {
                toys[day, week] = Microsoft.VisualBasic.Interaction.InputBox("Please enter value for Day " + (day + 1) + " in week " + (week + 1) + ".");

I cant seem to figure out how to convert the day and week in the inputbox line to INT.
I was required to use the VB inputbox for part of my college work so have been messing around with it for quite some time and im out of ideas.

Any ideas or help would be greatly appreciated! Thanks

You should do something like this:

C#

int tempVal = 0;
if (int.TryParse(Microsoft.VisualBasic.Interaction.InputBox("Please enter value for Day " + (day + 1) + " in week " + (week + 1) + "."), out tempVal)
{
    toys[day, week] = tempVal; 
}
else
{
    MessageBox.Show("Invalid entry");
    day--;
    continue;
}

int.TryParse() will parse the data into an integer, and it adds a check for valid data.

Oh so i had to make a temp value and then do the int.parse of the whole inputbox to that?
I was trying to int.parse within the inputbox which must have been the issue.

Thank you :)
