Hi Guys,
I am trying to overcome the headaches involved with maintaining the
dialogs for our MSI solutions and so have looked at the managed code
path.
While I know some of you will shun me for such a solution, I am merely
experimenting with the concept of using managed code to overcome one of
our biggest time wasters with MSI installers which is all the dialog
screens use to set properties. We have a series of MSI's all which
differ slightly from site to site and so I was looking at inheriting
winforms and making the tweaks there (removal of properties, addition of
properties, etc.
Onto the actual problem itself; I have setup a DTF custom action with
the dialog class in it which is created and called when run, what I am
having trouble with is slotting the custom action into the UI sequence
nicely. I wish for it to between the CustomizeDlg and VerifyReadyDlg
dialogs. Right now I have a modified WixUI_FeatureTree fragment which I
have put in the following code for the customizeDlg Dialog.
<Publish Dialog="CustomizeDlg" Control="Next" Event="EndDialog"
Value="Return" Order="2">1</Publish>
<Publish Dialog="CustomizeDlg" Control="Next" Event="DoAction"
Value="CA_ConfigUI" Order="1">1</Publish>
The two problems I have is once the 'EndDialog' is sent it immediately
begins the installation which I guess makes sense. Second is that I am
trying to invoke the session.Message(InstallMessage.ShowDialog, record)
method to start up final VerifyReadyDlg but I can find very little
information about this wrapper as the MsiProcessMessage API call seems
to not mention the Install Message.
My other thoughts were to just include a placeholder dialog in between
the two which would act as the container for invoking the custom action
but again I wanted something a bit more clean.
Any ideas on how to cleanly invoke a custom action in the middle of two
dialogs (while displaying no dialog boxes on the screen) and how to
continue the dialogs once the custom action is complete?
Thanks,
Murray
