The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Using VBA to edit record and delete records
Zone: Access Coding/Macros
Tags: Microsoft, Access, 2007
I have table (supplier) which simply combines two primary keys from two other tables Contacts and Items, supplier uses the primary key from items as its own primary key. In a certain form there are two list boxes and an option box with 3 radio buttons. The 3 options are, Do nothing, Change to another free item and delete item. The first list box uses a query to show all items that are currently attached to the contact which is in question (as a contact can have more than one different item) from the supplier table.  The other list box runs a similar query that compares the items in the supplier table and those that are in the items table, and displays those that are not in supplier. These are free items and are awaiting to be combined with a contact in the supplier table. When the first and third options are selected the second list box is disabled, when  the second option is selected the second list box is enabled. What I want to happen is the user selects an option from the first list box, then choose an option, should that be option 1, nothing should happen. When option 2 is selected, the itemID from the first list box is replaced by that in the second list box. When the third option is selected the record selected in the first list box should be deleted. These events are triggered by a button click. I am currently using the code shown to achieve this, nothing happens to any records although there is no errors. Any suggestions?

What are the "Data Value" for the 3 options in your Option Group? Open your form in Design view, the select the option button or checkbox you're using and make sure that the Data Values for those controls correspond to the values you are using in your Select Case.

Are you sure you're referring to the lstItems listbox correctly? Generally you use Me.lstItems.Column(0) to refer to a specific value in the listbox (note that Columns are zero-based, so Column(0) is the first column). The "value" of your listbox may not be the actual value you expect.

Are your listboxes set to multiselect? If so, you'll have to modify this code.

Easiest way to verify this is to set a breakpoint in your code, then "run" it by clicking your command button. To set a breakpoint, place your cursor in the first or second line of your code and press F9 ... then click the button and you should be thrown into the Editor window. Use the F8 key to step through your code. You can also use the Immediate window to examine the values of the various items ... for example to see the value of the first column in your lstItems listbox type this in the Immediate window and press Enter:

?Me.lstItems.Column(0)

Also: I don't see the need to use Recordsets to do this ... straight SQL would be faster, assuming you don't need a "handle" on the data afterwards.

For the Second Case:

CurrentProject.Connection.Execute "UPDATE Supplier SET ItemID=" & Me.lstFreeItems & " WHERE ItemID=" & Me.lstItems

Third Case:

CurrentProject.Connection.Execute "DELETE * FROM Supplier WHERE ItemID =" & Me.LstItems

Accepted Solution

Perfect solution, used the SQL statements in the end as wouldnt work the other way.
