only part of the data.

this piece of data means, for this module (subject, EG1001), these students(112960A,114424H, ... ) are taking it

i want to compare this 2 datasets to get the modulecode conflictive list.

Example:
paper 1 : EG1832
Paper 2 : EG1833,EG1952,EG1903
Common Students: 5
Paper 10:Paper20 = 30 students (AdminNo)

Im actually doing a data loader for exam scheduling data.

Anyone give me a head start on how should i go about doing this in the easiest method, simplest to understand? Let me know of any possible ways i could do this.

i dont mind to have to transfer the data from excel to access database first, but preferrably by coding.

Thanks in advance!

If you are storing large amounts of data, which it looks like you are, I suggest a database backend.

A table for students, classes and a junction table:

tblClasses
ID | Class | Comments
Auto | VarChar | VarChar

tblStudents
ID | Name | StudentNumber
Auto | VarChar | VarChar

tblLink
ID | tblStudent_ID | tblClassesID
Auto| Integer (FK) | Integer (FK)

Classes will look like:

0,SEG-AMK EG1832 Mechanics and Materials 286 1.5,EG1832
1,SEG-AMK EG1833 Electrical Principles 375 1.5,EG1833 EG1952 EG1903

Students will look like:

0,John Doe, 130019K
1,Woody Woodpecker,130020D

Your Junction Table will look like

0,1,0 - Woody is taking Mechanics and Materals 286
0,1,1 - Woody is taking Electrical Principles 375
0,0,0 - John is taking Mechanics and Materials 286

thanks for that. but i think its too much for me. is there any other easier way?

paper 1 : EG1832
Paper 2 : EG1833,EG1952,EG1903
Common Students: 5, then:
giving output:
ConflictPaper    No.Students   AdminNo
Paper 10:Paper20  30           111411H 163722U

displaying in multi line textbox or DGV
