I have an Access form with a combobox on it that I use to look up records in a table. What code do I put under a command button to delete the selected combobox record? Thank you.

An additional piece of information:  My table has 4 fields.  the first 3 fields make up the primary key.  The combobox has 4 columns.

Post your table and field names with examples of the type of data stored in each field.

Do you want this to happen immediately after the user selects a value in the Combo Box???

Here's what I'm trying to do:

MyTable has 4 fields:

Field1
Field2
Field3
Field4

Fields 1, 2 and 3 make up the primary key, so Field4 isn't really relevant.

I have a combobox to select a record.  The combobox has a Column Count of 4.  Column0 displays Field1, Column1 displays Field2, Column2 displays Field3 and Column3 displays Field4.

Note: I think the column counts for comboboxes start at 0. That's why I'm using 0 instead of 1 for my description.

Let's say I make a combobox selection.  The combobox is now populated.  I want to click a command button to delete the record appearing in the combobox.

In plain English:    If ((Field1 = Combobox.Column(0)) and
                                (Field2 = Combobox.Column(1)) and
                                (Field3 = Combobox.Column(2)))
                               then delete record

Thank you

Use the OnClick Event of your Command Button as shown below ....

CurrentDB.Execute  "DELETE FROM YourTable WHERE Field1 = '" & Me.Combobox.Column(0) & "' AND Field2 = '" & Me.Combobox.Column(1) & "' AND Field3 = '" & Me.Combobox.Column(2) & "';"

More specific ...

CurrentDB.Execute  "DELETE * FROM YourTable WHERE Field1 = '" & Me.Combobox.Column(0) & "' AND Field2 = '" & Me.Combobox.Column(1) & "' AND Field3 = '" & Me.Combobox.Column(2) & "';"

Also, let me know if Fields 1,2 and 3 are not text field.

I haven't tried your code yet but to answer your question, Fields 1, 2 and 3 are text fields and I'm already limiting what can be entered into through code and "limit to list" comboboxes for my seperate Add Records procedure.

OK. It's working except for one thing.  After a record gets deleted, the combobox shows:

#Deleted  #Deleted #Deleted #Deleted  for each record I delete.

 Any thoughts on how to clear that out? Is there a way to refresh or requery after clicking the delete button so those line items won't appear in the combobox?  Thanks.

Ok, then this should work ....

CurrentDB.Execute  "DELETE * FROM YourTable WHERE Field1 = '" & Me.Combobox.Column(0) & "' AND Field2 = '" & Me.Combobox.Column(1) & "' AND Field3 = '" & Me.Combobox.Column(2) & "';"

Also, "Me" refers to the current form object.  You can also specify the form name as shown below.

Forms!YourFormName!Combobox.Column(1)

Try this ... after you run the delete SQL.

Me.Combobox.Requery
