Thanks d_stranz for replying .
Debugger does not give any message, no errors but i do not get any result in the list box or in the line edits. But at the same time for other keys i am getting their details.
Is it due to acess limitation?
if so then how to overcome it.
Also i wanted to get last login time and shutdown time of the user using QT4 and display it on the lineEdits , is there any way of getting it?
Please response to this.
