i have written a program in C and it works fine when i run its EXE from Windows Command Line (cmd) or just double click it.

but from unknown reason (unknown for me that is) when i run it from a different program i have written in Visual Basic it will not print to screen while it will do its job perfectly.

this is my code in VB

ArgumentString_Processing = CSVPathString & "\ " & Mid(Extraction_tmpList.Item(j), 5, 4) & " " & Extraction_tmpList.Item(j)

Process.Start(EXEPathString & "Proc20.exe", ArgumentString_Processing)

the "Proc20.exe" is the program i wrote in C

again, it works fine but will not write anything in the window like it would if i run its EXE from the windows cmd or double click

in the C program i used "printf" through-out the code.

any help / thoughts would be appriciated .

thanks

VB does not run in a console window, therefore the output won't be displayed in the VB window. The progam is probably opening a console window to run, and when the program exits, the window closes. Try adding getchar() to the bottom of your program just before the return statement.

yes the VB program opens a console window to run
i tried "getch()" i tried fprintf(stdout,"text") tried cout<< "text" , nothing...

i am so so stupid...!!!! after all the testings i made i just needed to use cprintf and chage the color with textcolor !!!!
weird!
the most obvuise solution is always right there where you would least expect it...
