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.

in my visual basic 2008 express edition project I have 2 forms (paxreportfrm,paxsearchfrm).I want to give inputs in paxreportfrm and save the record(which is working fine).then in paxsearchfrm i want to search depending on multiple criteria (working ok).when i click on the record which is in gridview in the search form,opens up the paxreportfrm again with all the details of that specific record (working fine). 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.

View 3 RepliesI have an MS Access database that has a field called DeletedDate. I want to use a Delete statement that will delete the record(s) when DeleteDate is 30 days old or older. I have tried several different Delete statements but none seem to work properly. They will always delete some of the records, but will leave some records where either DeleteDate is older than 30 days or will delete recored where DeleteDate is not yet 30 days old. I have tried these using DeleteDate as a Text field and as a Date/Time field. Which should I use? These are the Delete Statements that I have used:

This is such a basic question, I'm almost embarassed to ask it. How do I loop through seleted rows in a DataGridView and remove the rows?I've tried this, but it doesn't work. After one row is removed, the index is all screwed up.

I have a List of an object, set to DataSource of a BindingSource, set to DataSource of a DataGridView. Then I added a DataGridViewButtonColumn which I want a click to remove that record from the collection. So I simply call collection. RemoveAt (e.rowIndex) from the DataGridView CellClick event. However this produces an IndexOutOfRange Exception; "1 does not have a value"..
So is happening here? I have maybe a vague idea, but would like to understand exactly which events are failing etc.. and what do i need to do to perform this action properly?
EDIT: This seems not to happen if I use a BindingList.. But when using a List, I get this problem..
