Use the exit event and if you want it to remain in the combobox, set the
argument

Cancel = True

I have a form with a number of combo list box controls. I have
establish
a
TabIndex sequence from one combo box to the next. The problem I want to
edit for a null entry. In other words, the entry into the combo box
should
be made to be mandatory.

I have an If-Else code block that traps the null entry and issues an
error
message. Then, I use the .SetFocus property to try to force the cursor
to
the combo box with the null entry. But, then the TabIndex seems to take
over and moves the cursor to the next control, which I don't want. How
can
I keep the cursor in the combo box to get the user to correct the entry?
