Dear Experts,<br style="font-family: Times New Roman,Times,serif;"><br style="font-family: Times New Roman,Times,serif;">I am trying to login to Pro/INTRALINK using the PDMConnectToPDM() api but it fails to connect with message "Invalid Multibyte string" without any other error message at the same API. I did followed procedure suggested by PTC to use PDMMultibyteStringToPTCSTRING for Unicode support as per Appendix B is followed but the results is same. :-(<br style="font-family: Times New Roman,Times,serif;"><br style="font-family: Times New Roman,Times,serif;">I am suspecting either windows XP 64 bit or compiler problem. I am using Pro/INTRALINK 3.4 - M062 with Visual Studio 2005.<br style="font-family: Times New Roman,Times,serif;"><br style="font-family: Times New Roman,Times,serif;">Thanks in advance.<br style="font-family: Times New Roman,Times,serif;"><br style="font-family: Times New Roman,Times,serif;">Regards,<br style="font-family: Times New Roman,Times,serif;">Akash<br style="font-family: Times New Roman,Times,serif;">
