hello there i'm in Psoc creattor 4.2 and i'm working code exemple i didn't change anything in the project i tried to build but i have this error "Unable to open file from disk: (A window with the key 'K:\Documents\PSoC Creator\project adress\CYPD3175-24LQXQ_pa_direct_fb.cydsn\Generated_Source\PSoC4\project.h' is already being managed by the dock manager. Create a unique key to add the window.)" i generated folder i can see the project.h with "?" symbol what does that means how i can i fix the problem ?
Can you please mention which code example are you following?
If it builds successfully with the older version of PSoC Creator, one of the reasons for build to fail may be the error in placing and routing with the newer Version of PSoC Creator. You can go through the section 'Migrating from Older PSoC Creator Versions' in the PSoC Creator User Guide by Open PSoC Creator -> Help -> PSoC Creator User Guide.
Please let us know in case of further clarifications.
