BTW I've been trying to suggest MSI `pure` ways of solving the problem.  If 
custom actions are acceptable, you could just inline a MessageBox type call 
within your CA white transitioning from the first dialog to the second.

dialog in the SpawnDialog chain?     Sorry, MSI doesn't support that.   To do 
that you'd have to make this a standard interior dialog with back/next buttons 
to take you to the original dialog and the VerifyReadyDialog.   To achieve the 
Yes/No story you would use a RadioCombo with Yes and No options.   Then on the 
next button you would order a DoAction CA conditioned on the Yes option being 
selected followed by a NewDialog to the VerifyReadyDialog.
   
  Make sense?

          Thanks for your help, that was exactly what I was looking for.  I’m 
having a slight problem with my implementation though.  After the question 
dialog pops up, the install isn’t proceeding to the next dialog, but staying on 
the same dialog.  I tried adding the ‘Order’ attribute, but then the 
AskConfigureSQL dialog didn’t show at all.
   
  Here’s the relevant section of my customized WixUI_Modo.wxs file:
   
  <Publish Dialog="SetupTypeDlg" Control="TypicalButton" Event="SpawnDialog" 
Value="AskConfigureSQL">1</Publish>
  <Publish Dialog="SetupTypeDlg" Control="TypicalButton" Event="NewDialog" 
Value="VerifyReadyDlg">1</Publish>
   
  Can anyone offer any advice?
   
  Thanks

    When would you like the Modal dialog to appear?  If during the UI sequence, 
 just create a Dialog with Yes and No controls and call it with a SpawnDialog 
ControlEvent.   From the Yes control's ControlEvent you can then call a 
DoAction ControlEvent to fire your CA.

     

    If not from the UI Sequence,  I don't really reccomend this since all user 
input should be collected up front.  Do the same thing as above only set a 
PUBLIC property ( and list it in SecureCustomProperties ) and then use that 
during the execute sequence to conditionally call your custom action(s) ( 
uninstall, install, rollback, commit )

      Hi,

     

    I’ve been searching the archives trying to find out if I can do this, but I 
can’t find out how I’d go about it.

     

    I would like to be able to pop up a message box, asking the user a 
question, with ‘yes’ and ‘no’ buttons.

     

    If the user presses ‘Yes’, I would like a CustomAction to execute.

     

    Is this possible?

     

    Thanks
