    I make you my apologise for my bad english, and i'm newer to programming, please read all; now:

    The OS is WINDOWS 7 Professional 64 bit and the version of Qt is Desktop Qt 5.5.1 MinGW 32 bit

    On internet i found this code to find the application that run on my computer then the goal is : send/emulate a keypress (for esample F5) to an other application (in this case to AtmelStudio) for more details go on comment line who is marked [ //**AD**// ] in file mainwindow.cpp; in
