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.

Now i want to update the existing record which has been populated from the gridviw of the paxsearchfrm and also want to have the option to delete the record.I am using the datacontrols(wizard) to make connection with the access2007 database.can someone give me some example of how to do the Edit and delete in the database pls.I already have a save button on the paxreportfrm(if i click on that, after changing the details on existing record, it just saves IT as a new record).so i really need something which will actually save the modifications on the existing record AND ALSO WILL BE ABLE TO DELETE IT FROM THE database. I have tried couple of methods but none of them are working.

I have been asked to fix a Community Server forum where thousands of users were created via a script. All of their profile pages are SEOspam for prescription drugs, etc. The forum was not using email verification or admin approval for newly registered users. I turned on the latter for now, but captcha would be nice.

How would I access a specific record and put it into a variable to compare against user input?I have a table CASHIERS and part of that table is a BadgeID and a PIN number. What I want to do is when a cashier swipes there badge to logon to a POS.. it searches the DB to see if the cashier exists. Then, once it establishes that they do exist, it pulls their PIN # and prompts them to enter it. It compares the data retrieved from the DB to the data that they entered.
