Re: Datagridview control

Just get the description textbox user enters description into and pass it.

c# Syntax (Toggle Plain Text)
int HowManyOccurance(string str, char charToSearchFor)
        {
            int numberOfOccurance = 0;
            CharEnumerator ce = str.GetEnumerator();
            while(ce.MoveNext())
            {
                if (ce.Current == charToSearchFor)
                    numberOfOccurance++;
            }
            return numberOfOccurance;
        }
 
{
if(HowManyOccurance(yourTextBox.Text, '\n') <=10)
MessageBox.Show("Correct");
else
MessageBox.Show("Please make it shorter, just 10 lines permitted");
}
int HowManyOccurance(string str, char charToSearchFor)
        {
            int numberOfOccurance = 0;
            CharEnumerator ce = str.GetEnumerator();
            while(ce.MoveNext())
            {
                if (ce.Current == charToSearchFor)
                    numberOfOccurance++;
            }
            return numberOfOccurance;
        }

{
if(HowManyOccurance(yourTextBox.Text, '\n') <=10)
MessageBox.Show("Correct");
else
MessageBox.Show("Please make it shorter, just 10 lines permitted");
}
