Problems with Q&E Driver with VBasic and Informix

I have some problems with the ldllsqlw.dll library provided by Q&E Software and I-NET PC to manage INFORMIX databases through ODBC. The layers I use are: DOS 6.0 FTP PC/TCP 2.3 I-NET 4.10 Q&E driver for Informix ODBC VB PRO 3.0 Q&E recommends the ldllsqlw.dll library must be in conventional memory, so it provides a utility to use at windows startup to force this. These are some of the problems I have: - Once I have got a connection error, the I-net layer returns an error (Unknown error -854) and remains busy, so the only thing I can do is reboot the computer. This problem is a known-error for Informix. - If I make an .exe file for a vb application, I can execute the application only once. The second time I got a GPF, sometimes in VBRUN300.DLL, sometimes in LDLLSQLW.DLL. I could solve this problem unloading the dll, but the I-net layer remains "busy", so ALT-CTRL-DEL is again the only way. - Sometimes, "An error in your application ..." message from vb or a GPF appears "ramdomly"; always when an ODBC call is made. These are some of my questions: - Is there another 3th party dll's for accessing Informix via ODBC? - Have Informix already released I-Net 5.10? - Q&E Technical Support FAX/PHONE or E-mail address? - Any bibliography you can suggest to understand what's happening? - Any utility to trace the vb application and odbc calls? Any suggestion would be of great help. --- Thanks in advance ale@pal07.ured.com.ar
