Hello,
I am making a Scientific Calculator which is nearly finished for my school project. Now, I need to make a History functions so that when ever the "equal" button is pressed it enters the equation into the History form with the Date and Time which can also be saved. So can someone help me do this??

Thanks.

Create a list and store the values as you do the calculations. You can then write the list entries to a file at a later point.

Create a new class that will hold your values (number and DateTime). Then each time the equals buttom is pressed you create a new object of this class and add it to the list, or write it to the file. See https://www.google.com/search?q=vb.net+list for some suggestions on the use of lists.
