The old version of Informix does not support multitple user access. When 1
user perform "Update" function, the other peoples who try to "View" the data
will get error message. Thats mean i have to control the multiple user access
manullay by using coding in VB. May be i have to set "Loack by Row" in Informix,
and "Isolation level - like commitedread, dirtyread...." at VB. But i'm not
familiar on how to applies such code in my VB. Do anyone can give me some
sample code? Thanks
