When I open the MPLAB IDE V.92, the red circled areas in the attachment are empty. They were not like that before. How can I make the program show them? Thx.
That looks like you have opened a program file without making a project. For example, this window:
only shows in a project and gives the options Release or Debug for your build.
As for the project tree, I don't usually have it show in the program window (it is in a separate window), but it seems reasonable that unless you have an active project open, that tree would not show.
I use MPLAB 8.92 , but I do not us C. I must apologize if these comments are completely off base.
