View 4 RepliesI have just started using databases, but I am totally stuck. I made a database and table using MS Access. The table has three columns. ID, Code, and Letter. Basically, the Code column stores a number for each letter (eg. 1 = A, 2 = B, 3 = C, etc.)
Table:
|ID|Code|Letter|
| 2| 1| A|
| 3| 2| B|
| 4| 3| C|
etc.
This table is just for reference for my program, and I don't need to change any values. But I need a step by step guide to link this table to VB 2010 and convert the values of the table to an array. For example: convert the table into the array "example" which means that example(1) = A, example(2) = B, example(3) = C and so on.

View 1 RepliesI have two Access database, say database One.mdb and Two.mdb. I want to use VB2005 to export tblCustomer from One.mdb to Two.mdb, and replace the existing tblCustomer in Two.mdb, during run time. I basically want to simulate the export function that is available in MS Access (which can export one table from one Access database to another) with VB2005 during run time. I can think of a way by querying the table to a dataset and then delete everything on the other database before filling the table in that database with the dataset. However, there should be something simpler and faster than that, shouldn't it? Any idea?
