I am using railway reservation project.
I am using for passenger Reservation Train_No,Boogie_no,Seat_No.
I have problem with While Selecting Same Train_No,Boogie_no,Seat_No from two Pc's.
It gives error duplicate values.
What I will do When Two user selecting same values simultaneously.
Please Suggest me Idea for this Project.
I am Using Visual Basic 6.0 for Front End and Oracle 9i for Back end.

this isn't necessarily pertinent to vb, but normally what you would do is create a locked column in the database, whenever they start reserving set it to locked and not allow any other users to access when the column is set
