To be precise, my batch file named show-preview.bat consist of only two commands:
latex first-program.tex
dvipng first-program.dvi
When I run show-preview.bat from cmd then they run successfully and I obtain the desired result.
But when I use exec('show-preview.bat'); I am finding the following error in apache_error_log:
'latex' is not recognized as an internal or external command, operable program or batch file.
'dvipng' is not recognized as an internal or external command, operable program or batch file.
Whereas both of these commands are working fine from the command prompt......... what you say?
I also tried to pass the absolute path of the bat file within exec() but it also do not work. Any idea?
