Next Button

Question

Hey Guys! I want to execute below code using 'NEXT' button ,
for (int j = 1; j < myArray.Length; j++)
{
int key = myArray[j];
int i = j - 1;

while (i >= 0 && myArray[i] > key)
{
int temp = key;
myArray[i + 1] = myArray[i];
myArray[i] = temp;
i = i - 1;

}
}

Like this:http://www.cs.oswego.edu/~mohammad/classes/csc241/samples/sort/Sort2-E.html I want to run this code's each line when my "NEXT" button push. I mean 1st code line run when 1st time push button clicked, and 2nd line run after 2nd time clicked 'NEXT' button!
I really would appreciate some help or at least a point in the right direction. I generally search in google, but have been doing so for hours with no luck. Hopefully someone here can help?

You'll need to make a lot more changes to do that. See if the following will work: // add these private fields private int j = 1; private int key = 0; private int i = 0; private bool inner = false; private btnNext_Click(object sender EventArgs e) { if (j { if (!inner) { key = myArray[j]; i = j - 1; inner = true; } else { if (i >= 0 && myArray[i] > key) { int temp = key; myArray[i + 1] = myArray[i]; myArray[i] = temp; i = i - 1; } else { inner = false; j++; // increment j } } } else { btnNext.Enabled = false; // disable button as further presses are pointless } }

If you mean that you want successive iterations of the 'j' loop to run each time you press the next button then you need to save 'j' to a private field of the form like this: // add this private field private int j = 1; private btnNext_Click(object sender EventArgs e) { if (j { int key = myArray[j]; int i = j - 1; while (i >= 0 && myArray[i] > key) { int temp = key; myArray[i + 1] = myArray[i]; myArray[i] = temp; i = i - 1; } j++; // increment j } else { btnNext.Enabled = false; // disable button as further presses are pointless } }

@Vulpes: Hey Thanx alot! Its a good solution! but there is a another problem When your solution applied it works to whole code segment ! I want to apply like that method for while loop also along with that. I mean when 1st time button press it go through code and 2nd time press it it go through while loop and at each time button press go through while loop and after iteration is over again go through whole code as before when button pressed. If you can suggest a way to do this im really thankful to you!
