a C .exe doesn't read writeToStdin

Please help:

At first I thought QProcess is wrong now by putting in the wroteToStdin signal I determined my .exe written in C doesn't read the stdin.

This is the code:

Code:

---

fgets(serialnmr,sizeof(serialnmr),stdin);

---

serialnmr is char * and scanf nor gets works :(

Remember that you need a newline when reading using scanf() or gets().

just to make sure I understand:

for using scanf() and gets() the writeToStdin must be:

Code:

---

proc->writeToStdin("tester\n");

---

because my code in my QT side is:

Code:

---

proc->writeToStdin("tester\n");

---

but I use it with:

Code:

---

fgets(serialnmr,sizeof(serialnmr),stdin);

---

and another thing I see is that nothing is displayed using readFromStdout until the program (my.exe) has exited.

I'm really in a bind please help!

It doesn't matter. You still need the newline to flush the stdin buffer of your application.

Maybe you are missing newlines here, too... In the output buffer this time. You can use fflush() instead of the newline to force the flush too.
