SQL server Express is not installed after uninstall

[Rupesh Kumar Swami]

hi all, i am trying to install SQL express 2005 from following code str = Application.StartupPath & "\SQLEXPR32\setup.exe /qb ADDLOCAL=ALL INSTANCENAME=" & InstanceName & " SECURITYMODE=SQL SAPWD=mypassword DISABLENETWORKPROTOCOLS=0 " Shell(str, AppWinStyle.Hide, True) it works well for first time. When i install from above code and uninstall from Control panel and then once again i execute the above code then it does not install the SQL server Express I think Uninstall from control panel does not completely remove the SQL server Express.Its require some more steps Whether anybody can suggest me that how can i completely uninstall the SQL server Express from my machine ?
