how can I insert text into an existing string? I am trying to interpret a solution in an earlier post "How do I insert test into a textbox in the middl of existing text"
solution given was int insertionlocation = 4;string newText = "text to insert";if (textBox1.Text.Length < insertionlocation) textBox1.Text = textBox1.Text.Substring(0, insertionlocation) + newText + textBox1.Text.Substring(insertionlocation); else textBox1.Text = textBox1.Text + newText;
I must determine both how and where I need to implement this solution.What follows is my work in progress. Keep in mind things are added and deleted as I work with it saving a user entry to a file
