FocusPrb: Keeping Track of Last Control After MsgBox Invoked in LostFocus Event

The sample FOCUS.MAK project contains the files FORM1.FRM and FORM2.FRM.

The idea of the sample is to demonstrate how to design your own message box
for validation checking. Because of the problem with using MSGBOX(ie modal
window). You can try something like this sample instead. The article that
talks more on the problem is: Q85856.

You first want to enter some text in the Text1 box. Then press the Tab key
to move the focus to the next control(ie Text2), you will see a customized
message box(ie form2) become displayed. Select either the Yes of No button to
proceed on. If you select the Yes button, then the focus will be in the
Text2 text box.  

The same steps need to be choosen to get the focus from the Text2 text box to
the Text3 text box.
