I already made a simple program, then added a button to the first form .
I added another form to my project and named it frmFullScreen (with file name frmFullScreen.cs)
in the button I added to Form1 I wrote this code :
the methods didn't appear to the help type in the code viewer and on compiling it didn't work
I then made a change and wrote this :
the line this.Hide() worked only when it was alone, !! but when I added the other line the second one gave me a compilation error. I don't know where the bug is , It is getting me mad . I made nothing else , just what I wrote here. If there were something to be modified in settings or some other coded to be added ... Plz tell me how to solve that program to proceed on my project.
