Hi Behdad By the way,I had included the test program, (I had pasted it.) Regards Ali On 5/8/06, Ali Majdzadeh <gmail.com">ali.majdzadehgmail.com> wrote: Hi Behdad Thanks for your response.

Hi Behdad I think I solved the problem, my test program ran correctly and I was able to change fonts. I think the problem was about the configuration of installed fonts. Thanks a lot anyway Regards Ali On 5/8/06, Ali Majdzadeh <gmail.com">ali.majdzadehgmail.com> wrote: Hi Behdad By the way,I had included the test program, (I had pasted it.)
