Usage of SetForegroundWindow
and other methods of setting of focus has a lot of restrictions. If you really want to be sure, that the started process will receive focus I recommend you to use following native (unmanaged) functions
SystemParametersInfo (SPI_GETFOREGROUNDLOCKTIMEOUT, 0, (PVOID)&dwLockedTimeout, 0);
SystemParametersInfo (SPI_SETFOREGROUNDLOCKTIMEOUT, 0, (PVOID)0,
SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);
before process start and restore
SystemParametersInfo (SPI_SETFOREGROUNDLOCKTIMEOUT, 0, (PVOID)&dwLockedTimeout,
SPIF_SENDWININICHANGE | SPIF_UPDATEINIFILE);
at the end. A call like
WaitForInputIdle (pi.hProcess, 5000);
after the program start and before restoring of SPI_SETFOREGROUNDLOCKTIMEOUT
can be also helpful if you will have problems with immediate
