About the realization of back and forward functions

epsilong123

There is a DirectoryListBox control and a DriveListBox control
There are 2 buttons, one is for directory forward, the other is for directory back
For example, the current directory is C:\aaaa
Go to directory F:\ppp
Press back at this time, DirectoryListBox will automatically jump back to C:\aaaa
Press forward again to jump back to F:\ppp
Hope to record about 3 changes,
For example, it is now C:\aaaa
Jump to F:\ppp
Jump to E:\ddd again
Jump to D:\eee again
If you press back, you will jump back one by one, and forward will be the opposite.

I plan to implement it with a stack, but the idea is still not clear
Hope it can help me, thanks

Could you please give me specific ideas?

Now I use the list, but I can only go back to the previous one, and the previous one will not work. Please help me heroes

An array records the operation steps, and the array index increases by one or decreases by one to move forward and backward.

I am now putting the added list item in the change event of DirectoryListBox, but the effect is not very good.After going back once, the list item changes again, and there is no index function in TStingList, so I can't return the item based on the first item. String
I'm thinking, cancel this function, it makes me have a headache
