hi friends/experts,
i am running another program (ex: fps.c) inside my qt application by QProcess() , that program is a device handler so i run that "fps.c "program with my qt application .
that device is a finger print scanner so first i get the output from fps.c as "device ready and then put the finger"
after that i put my finger it fps.out shows again output as "image scanned and saved as" .....
this is the usual running of "fps.c"
when i use this program run the output of fps.c through QProcess in my Qt app and using signal readyReadStandardOutput() i get the output and displaying that in a label by using readAllStandardOutput() ... this is my plan
but the label shows output as "device ready" "put the finger" "image scanned and saved as" after i scanned my finger then only i can get the output but its not coming as per order as "device ready and then put the finger"
i will scan my finger then displaying "image scanned and saved as.."
why its not coming like that how can i solve that .... please help me ...
