Coping The Active Record In A Form To Another Table And Then Deleting The Record From The Original Table?

Aug 18, 2011

I am leaning VB and have created a basic inventory app for work that consist of 4 tables, CurrentInventory, Surplus, Staff and Category. Each of these tables have a corresponding form. My question is with the CurrentInventory and Surplus form/tables. I want a button on the CurrentInventory Form that when clicked the current record would be transferred to the Surplus table and deleted from the CurrentInventory table.I am assuming that I could somehow use the INSERT command to copy the current record to the surplus table but I am not sure how to accomplish this.

Jul 31, 2011

I have two tables Products and Categories with a many to many relationship. I am trying to copy the categories linked to one product (OriginalProduct) to another product (newProduct). The problem is when I execute the SaveChanges() method, I not only get the records in my linking table, but it also creates another copy of the categories in the categories table. I've tried this in many ways but here are the last couple that I've attempted:

' Copy Product/Categories

Way To Delete A Record

Aug 27, 2009

I have records in table1, if the records exist, it must copy into table2. I want to delete those records in a table1 once all the records are copied into another table2. Im still a beginner in database and with some researches, i found some tutorials on d internet how to connect with database, and the codes easy to understand so i came out with this program.This codes only do the copy part and i'm still lack of the delete part. i found 2 reference in msdn, but i'm not sure and not understand on the codes given.[code]...

its only delete one rows. But what if many records involved? Do i need to consider the EOF things? DO i need to use DataGridView? Becoz the code i did didn't use DataGridView at all. i dont want the records to be displayed, i just want it to running behind.

Insert Command - Record Is Not Added

Jan 4, 2010

I am having a problem with adding a record to a customer table in a Microsoft Access database. I have worked for hours reading my textbook and troubleshooting to no avail. The copy and paste below from VS is a little messy. When I execute this code below the record is not added and I do not get an error of any type. When I go into debug mode, all of the parameters are correct and everything looks good. If I open up Access I can manually add the record but using my program nothing happens. All datatypes are string in VS and text in Access.

First an instance of the Customer Class is created and this seems to be successful. But when I take that customer object and run the AddCustomer method of the customer class it is not successful in that the database does not reflect that the record was ever added. [Code]
