Hi !
I am writing a program which looks a lot like Norton Commander.
I have finished ( almost :-) user interface and tried to make my
program launch other programs and got stuck . I have never done it
before , so I looked up some functions in TC++ help. I found
ins system(const char *) and int spawnl(int, char *, NULL)
functions. The problem is when I spawn a child program with either of
this functions the execution never gets back to parent . The child
process terminates but the parent process does not resume.
Here is a part of my code :
char * ext=filename[pos]->get_part2(0);
if( !strcmp(ext,"bat") || !strcmp(ext,"BAT") || !strcmp(ext,"EXE")
|| !strcmp(ext,"COM") || !strcmp(ext,"exe") || !strcmp(ext,"EXE"))
{
panel1->kill();
panel2->kill();
int result=system(filename[pos]->get_filename());
panel1->refresh();
panel2->refresh();
}
