QProcess-startDetached and Console screen problem

Hi all,
I want to call external qt application and i'm using QProcess class. I wrote
windows shell extension to explorer and i use QProcess for calling my
exernal Qt application. Extension dll and my exteranal qt application use
same dll's. In first i was using QProcess-start() method but when external
qt application want to use shared dll(both Extension dll and external qt
application use) function external qt application waits for explorer.exe 's
finishing and do nothing.
But when i use QProcess-startDetached() working corrently but there is a
console screen . I don't want show console screen . How can i hide this
console screen ?Or how can i use QProcess-start() method correctly?
Thanks in advance
