    Hi all
    Darius here, and as you will see from this question, Im new to the world of programming.

    Im trying to write a program that i plan on using for the registration of students. It is Winform based, and consists of 9 textboxes that I use to gather data from the user. Now I have created a student class, and a hashtable to tempereraly store the gathered data in.
    Now my Question is, how do I go about extracting the data from the hashtable, and displaying it in either a new window, or back in the original textboxes from where it came in the first place. So in other words, if I type in the student number(key) in the textBox.1, I want the values(the data from the other 8 textboxes) to reappear in those textboxes as they were entered.
    I know there is no myTable.Show method, but im sure there has to be a way to do it. Can anyone tell me how?

    Thank you all, for any and all help.
    Darius

    How have you created the hash table? Is it a file that contains the data, or an array of structures within the program?

    public static bool TChekStudentIdExists(string strstudentID)
    {
    IDictionaryEnumerator en = objstudent.GetEnumerator();

    while (en.MoveNext())
    {
    string str = en.Key.ToString();
    if (str == strstudentID)
    return true;

    }
    if (objstudent.Count == 0)
    return true;
    else
    return false;
    }
