I need to move to the next employee from a struct array.

Question

I have this project pretty much complete except for changing the employee data from the array. I already have been graded for this project I would just like to know how to cycle through the array of employees. The name fields and the pay rate changes with the next button.

You also need to move the first textbox insetion out of the - while loop while (sr.Peek() != -1) { //Collects the data abd fills the array of structures. struc_EmployeeRecord EmpRecord = new struc_EmployeeRecord(); EmpRecord.firstname = sr.ReadLine(); EmpRecord.lastname = sr.ReadLine(); EmpRecord.payrate = sr.ReadLine(); //txtFirstName.Text = EmpRecord.firstname; //txtLastName.Text = EmpRecord.lastname; //txtPayRate.Text = EmpRecord.payrate; EmployeeRecordArray[arrayindex] = EmpRecord; arrayindex++; } txtFirstName.Text = EmployeeRecordArray[0].firstname;//start at first name in array txtLastName.Text = EmployeeRecordArray[0].lastname; txtPayRate.Text = EmployeeRecordArray[0].payrate; } catch { MessageBox.Show(File does not exist.); } In Vulpes code you will need add if statement so to ensure not incrementing currentIndex beyond size of the array. If it reaches array max reset to 0 When you instantiate - EmployeeRecordArray = new struc_EmployeeRecord[26]; To instantiate properly use int i = File.ReadAllLines(@Employee.txt).Length; int intIndex = i / 3; // count number of names EmployeeRecordArray = new struc_EmployeeRecord[intIndex];

The code to cycle through the elements of the struct array will be something like this: private int currentIndex = -1; // create private field to keep track of array index; use an impossible value to start with private void btnNext_Click(object sender EventArgs e) { currentIndex++; // so this will be zero when button first clicked if (currentIndex == EmployeeRecordArray.Length) currentIndex = 0; // wrap around to first element when end of array reached txtFirstName.Text = EmployeeRecordArray[currentIndex].firstname; txtLastName.Text = EmployeeRecordArray[currentIndex].lastname; txtPayRate.Text = EmployeeRecordArray[currentIndex].payrate; }

I have tried to see what I can get but still am confused on this one. All I really want is to have it working because I plan on modifying it for my own use afterwords. I can change the file if I need too. I learn by seeing and then doing. If you can help just let me know.

Don't hard code your paths to user file ie Employee.txt String path = @Employee.txt; - will look in same folder as your exe you need to move through EmployeeRecordArray eg private void btnNext_Click(object sender EventArgs e) { txtFirstName.Text = EmployeeRecordArray[1].firstname;// increment 1 as needed // fill other tectboxes as needed } See if you can work it out from here
