I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...
I have written this set of code that will update an Access Database row: (Total_RAM, Model, etc are just string variables)

My problem is the fact that one specific record called "Record.Asset_Tag" exists in the database, but I don't want to programically alter it. That will need to be typed in manually. However, even if I don't put in the line "Record.Asset_Tag = ...", it will overwrite anything in the field with a blank.How do I keep whatever is in the database unaltered in the Asset_Tag column?

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.

View 1 RepliesI am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

Get the current row that I wish to update delete the row that I wish to update Create a new row with the information from the row I wish to update plus the new binary It just doesnt seem very elegant, and I was hoping I could do the same thing with an update statement.
