How about this?
<?define InputValidated="SERVERNAME AND DATABASENAME AND
(USEINTEGRATEDSECURITY = 1 OR (DBUSERNAME AND DBPASSWORD))"?>
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17"
Default="yes" Text="Next">
<!-- Validate input -->
<Publish Event="SpawnDialog" Value="IncompleteInputErrorDlg">
NOT ($(var.InputValidated))
</Publish>
<Publish Event="NewDialog" Value="IISDlg">
$(var.InputValidated)
</Publish>
</Control>
Yes, I realize that this maintains the double-evaluation, but it is more
maintainable (since you type it only once) and the time to evaluate
shouldn't be long compared to the time required to use the UI via mouse
and/or keyboard.

Subject: [WiX-users] Input Validation
Hi all, what's the best way to validate that several required fields on a
dialog are filled in? I've done some searching on this list but haven't
found anything conclusive. Here's a snippet of a dialog that asks the user
to enter some database information:
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56" Height="17"
Default="yes" Text="Next">
<!-- Validate input -->
<Publish Event="SpawnDialog" Value="IncompleteInputErrorDlg">
NOT (SERVERNAME AND DATABASENAME AND (USEINTEGRATEDSECURITY = 1
OR (DBUSERNAME AND DBPASSWORD)))
</Publish>
<Publish Event="NewDialog" Value="IISDlg">
SERVERNAME AND DATABASENAME AND (USEINTEGRATEDSECURITY = 1 OR
(DBUSERNAME AND DBPASSWORD))
</Publish>
</Control>
This works, but I don't like repeating those two statements (albeit one
wrapped in a NOT). It seems like this is the only way I can get it to
validate every time. If I store the result of the main statement in a
property, the property doesn't get reset when going back or forward in the
wizard so therefore it only validates the input once. Any ideas?
