Title: Message
Hello, I don't know why that doesn't work -- I even looked back at a script I wrote (and which still works) and it does use the backticks, and it does get output from it, yet when I try an example as below, it does not!
 
Anybody have a good explanation for that????? I don't.

thank you. when i use $mystuff = `c:\hello.exe` (using the back ticks) nothing happens. when i use the quotes in this same format, naturally the text is displayed. when i use system('c:\hello.exe'), the return code (of zero) is displayed. when i use system('c:\exethatdoesnotexist.exe') the return code (of 256) is displayed. please keep in mind that all of this is through the browser.

thank you so much for your helps. any thoughts?

hi jon

when i do what you suggest, what displays is "C:\hello.exe" and not the output from hello.exe

maybe i am doing something really wrong.

thanks

 Hi,

Yes I can - any .pl will work well in the browser - as long as the calling of these .exe is not included.

Thanks
Mario

Can you run other .pl files from browser?

Hi 

Thank you for your responses. I'm a novice at this so apologies for not including the code. Here it is: 

# Program name:  hello.pl
print "Content-type: text/html\n\n";
print "<HTML><HEAD><TITLE> CGI/Perl First Try</TITLE></HEAD>\n";
print "<BODY BGCOLOR=Black TEXT=White>\n";
print "<H1><CENTER> Hello, World! </CENTER></H1>\n";
$mystuff = system(hello);
print "$mystuff\n";
print "</H2></BODY></HTML>\n"; 

In the command prompt, this works fine - obviously even displaying the <H1>, etc.. >From a browser absolutely nothing - eventually timing out. The two .exe are in the same directory as where the .pl is. 

Any ideas? 

Thank you so much,
Mario

Hello,

In a legacy development environment, a simple 'hello world' .exe needs a
companion .exe to run. calling the hello_world.exe from perl (using
system(hello_world) or my $ipstuff = `hello_world`; print($ipstuff);)
work great from the dos prompt - hence the companion .exe is being
called properly automatically.

when i try doing the same thing as a cgi script from a browser, nothing
ever happens - no matter where i put these two files.

any suggestion how i can get these combo .exe's to work from a browser?

thanks!
