How to call .exe (executable) file through code in ax 2012

Here I am calling .exe file through AX 2012. What I have done in this is created a Crystal report of AX and make it in .exe format. Now I am calling this through AX 2012 R3.

static void Callingcrystalreport(Args _args)

{

    WinAPI::shellExecute("D:\\BN\\WindowsFormsApplication2.exe");

}
