Saving the current field

This should be simple but as usual MS help can't answer the most simple of questions.

I have a form with a button. When the button is pressed it requeries the form. Unfortunately if a control in the form is being edited before the button is pressed it says I can't requery the form until the current field has been saved.
In VB is there a command to update/save a control?

Thanks for you time.

I've found a solution

sendkeys "+{enter}",true

Is there not a better way of doing this?

Try this

DoCmd.RunCommand acCmdSaveRecord
