How to create Property using Custom Action?

[vicky]

Hi!

I am using AI-6.4 and building an enterprise project. For custom actions, i am using VC++ 6.0 MFC DLL.
I would like to create some properties which will remain same(can be reset again) through out the MSI session i.e. after calling different custom action, it should not get deleted.
I want to do it using Custom Action. Is it possible? If yes, then how?
Plz provide me VC++ code to achieve this.

I've made Property "ZSHOW" (as a public prop) with default value of "Hide". I am setting this value in one of my UI_Custom_Actions, say "CA_1" and getting it in another UI_Custom_Action, say CA_2. But, haven't received the value set in CA_1. Actually, i am using "ZSHOW" to hide/show a check box of a dialog. Value of "ZSHOW" is being set according to conditions required to hide or show check box.

Thanks in anticipation.

Regards,
Vicky

Hi Vicky,

Please note that Windows Installer DLL custom actions need to be written in a specific way. For more details and a sample project please see the Serial Number Validation DLL article in the User Guide. For reading and setting a property you can use the MsiGetProperty and MsiSetProperty functions.

Hi Cosmin!

Plz read my post again, I know that MSISetProperty will set value of property and if property is not there, then , it will create that property in Property table. I've used this in one of my UI Custom actions but I want to use this property's value to hide/show my dialog controls. When, i was unable to do it, i create a property in Install Parameters page and tried to use it to hide/show my dialog controls, but, it is still of no use.

Plz help me to sort out the problem.
