I have got a PWS installed and have got the source code of CGI32.bas(This module initializes the CGI environment).But the problem is that Iam able to get a messagebox open through the remote PC but when it comes to sending back the HTML it gives an error saying HTTP headers not send.Iam using the PWS shipped with windows-95.Is it compatible for CGI?Another problem is that most probably the CGI data file which should have all the details of CGI to be executed is not being send as Iam not able to trap the command line arguments.Can you please help me out?If possible please suggest some books on CGI in VB.

What makes a cgi a cgi are the first lines of output...

Make sure you send the complete http header:

Send "Content-type: text/html" & Chr(10) & Chr(10)

with TWO linefeeds!
That are the all the http headers needed in a cgi
(unless your VB program writes other data than html - then the text/html would need to be changed to the mime type of the data you produce

Michel, see http://www.experts-exchange.com/Q.10059469 for why that's not the real problem here. The real problem is that VB has no builtin method for writing to STDOUT or reading from STDIN.

Alamo: Thanks - So far all beginner problems to do with cgi in any programming language has had to do with the content type header... I saw this a another one of these.

What a pain - most programming langages can write cgis straight out of the box - can it be run from a commandline? Ok it can be run as a cgi ;-)
