I created a custom dialog and stuck the forward and backward links in my copy
of WixUI_InstallDir.wxs:
<Publish Dialog="MyConfigDlg" Control="Back" Event="NewDialog"
Value="InstallDirDlg" Order="1">NOT Installed</Publish>
<Publish Dialog="MyConfigDlg" Control="Next" Event="NewDialog"
Value="VerifyReadyDlg" Order="2">NOT Installed</Publish>
I made a new wxs file with a fragment in it that describes my dialog. All
this seems to work.
I would like to have it so that when the user clicks the "next" button, I do
a custom action in a DLL to validate what they put in on my new dialog. I
already have this, too, and it also seems to work.
<Control Id="Next" Type="PushButton" X="236" Y="243" Width="56"
Height="17" Default="yes" Cancel="yes" Text="!(loc.WixUINext)" >
<Publish Event="DoAction" Value="ValidateMyStuff">1</Publish>
<Publish Event="NewDialog"
Value="VerifyReadyDlg"><![CDATA[MYSTUFFISVALID = "1"]]></Publish>
</Control>
The DLL returns a "0" or a "1" in MYSTUFFISVALID after parameter validation.
0 is bad, 1 is good.
What I'm trying to do is force the user back to my dialog to fix the errors,
and then they would click "NEXT" again, and I would repeat the validation...
How do I make the same dialog re-appear to keep the user on this dialog
until they enter the right stuff?
Is there an example of this somewhere that you know of?
Thanks, in advance.
Greg
