OnCanceling not being called

[dstoup]

I am running a Basic MSI project, and can't get the built-in function OnCanceling() to respond to a cancel button push. The documentation seems to indicate that this event is triggered whenever the uer presses a cancel button. Is there something else I need to do?

TIA

The OnCancelling() function applies only to "Standard" projects.

Take a look at the EndDialog control event in the msi docs. This gets called with the "Exit" argument on a concel request.

The documentation clearly states "OnBegin, OnEnd, OnCanceling, and OnHelp are the only event handlers supported in a Basic MSI project. " Where is the discrepancy????????

I do apologise...
I did not take into acount Installshield's tendancy to meddle.

I have kept my msi projects free of ISScript contamination and so was (wrongly) under the impression that the ISScript event handlers were part of the IScript engine.

I apologise for steering you wrong..

however, the docs also clearly state ..

OnCanceling, which responds to the Cancel event generated when the end user clicks the Cancel button in one of InstallShield Developer's built-in dialog boxes.

Logical to assume then that it won't get called from an MSI cancel event.

I am trying to get it to call from one of InstallShield Developer's built-in dialog boxes. I am currently not using any custom dialogs. That is why I assumed it would work.

"built-in" as in one of the msi dialogs pre generated for you (e.g. CustomSetup) or as in one of the dialogs listed under "Built-in dialog box" in the same help docs....

My reading of the docs is that the OnCancelling() event fires from one of the isscript built-in dialogs, and not from the pre generated msi dialogs.

Some clarification from someone high-up and all-knowing is probably a good idea..

I agree!!! The documentation is obviously to glib to be useful. I guess I'll just try to avoid anything InstallShield provided.
