Please Check mainwindow.cpp in backend directory of MIDAS demo3.

PLease check mainwindow.cpp in midas_usound_demo3_rel\miDAS\ultrasound\demo3\backend\src.

Line 642-646

642 strcpy(pUsParams->bpuFileName, fileNameB.toLocal8Bit().data());

 ~~~~~~~

643  strcpy(pUsParams->dpuFileName, fileNameColor.toLocal8Bit().data());

 ~~~~~~~~

644 setCmd.cmdBuf[MIDEND_CMD_BUFSIZE - 1] = '\0';

645

646 memcpy( &(setCmd.cmdBuf), pUsData, (MIDEND_CMD_BUFSIZE /*sizeof(MidEnd_UsParams_t)*/) );

           ~~~~~~

On line 642,643, codes set   pUsParams. But On line646, code uses UsData.

On line 644, code sets null for safity. But  line646 set data into cmdBuf[MIDEND_CMD_BUFSIZE - 1] .

These codes may not effect bad in fact.   But I can not understand them.

Please check mainwindow.cpp.

Thank you
