Hello, i have found a bug in KProcIO. i have found a bug in KProcIO. In fact, when i use readln(...) sometimes the line is not complete because there is a \0 char in the line and the "partial" parameter is not set to true. To fix that problem i have added the line recvbuffer.replace('\0', QByteArray("")); just before the line len=recvbuffer.find ('\n',rbi)-rbi; in the file kprocio.cpp I don't know if it is the good fix but it seems to work. bye -- Jimmy Gilles
