Hi, What manika wants is still unclear to me. Does he want to launch the programs at the client machine or at the server? If at server, exec() might work. If on windows client, giving link to the program in sys root, might not work. Neither of codes below worked on my machine. <?php //Code - A echo '<a href="C:\WINDOWS\system32\calc.exe">Calculator</a> '; //Code - B echo '<a href="file:///C:/WINDOWS/system32/calc.exe">Calculator</a> '; //Code - C echo '<a href="/WINDOWS/system32/calc.exe">Calculator</a> '; ?> Regards, Manda Krishna Srikanth http://www.krishnasrikanth.com php-objects@xxxxxxxxxxxxxxx wrote on 02/22/2008 02:28:59 PM: > <a href="\file\location\file.name">Click here to open your file</a> > > Windows should recognise the name and open the appropriate application, but > it's down to the users individual configuration. > > Rob. > > -----Original Message----- > From: php-objects@xxxxxxxxxxxxxxx [mailto:php-objects@xxxxxxxxxxxxxxx] On > Behalf Of manika bhatia > Sent: 22 February 2008 05:20 > To: php-objects@xxxxxxxxxxxxxxx > Subject: php script to run window program > > I have a button when I click on button I want to execute an outer file like i > upload file > but now i open it. > thanks > =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.
