Hi Ray
Thank you for your answer. Of course I pressed F5. The EXECUTE file is missing. I create a code after that pressig F5 but there is no .exe file only .PROGNAME.vshost.exe is. Below in the error list the next message is: Error 1 Error reading Win32 manifest file 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\default.win32manifest' -- 'A rendszer nem találja a megadott fájlt. ' probe1_100406
" 'A rendszer nem találja a megadott fájlt. ' probe1_100406 " is means the system can not find the given file.
I reinstalled the VS2010 but unfortunately this could not solved the problem.
