Hi, I have the following codes:
me.hide()
staff.show()
It run smoothly for the first time,but when I execute it for the second time,it occured the following errors:
Unable to copy file "obj\Debug\FYP.exe" to "bin\Debug\FYP.exe". The process cannot access the file 'bin\Debug\FYP.exe' because it is being used by another process.
May I know what is the problem???
