Refresh dependant properties on property change

[juan.01]

Hi,

I have added some custom properties in my installer.

• HOME_PATH = C:\Home

• CONFIG_PATH = [|HOME_PATH]\Configuration

• LOGS_PATH = [|HOME_PATH]\Logs

I have noticed that If during wizard I change HOME_PATH the others properties are not being refreshed. The only way to achieve that is using custom actions and putting them before path resolution execution stage.

This is the correct way or there is another way to refresh dependant properties?

With regards,

Hello,

Most likely, this happens because you are using a PseudoFormatted property, which is resolved at build time.

By default, properties referenced by PseudoFormatted ("[|propertyname]") field are resolved at build time. During installation only properties used in Formatted data fields are resolved.

During the installation you need to use only properties referenced by Formatted data types, for example "[HOME_PATH]".

More details on our Windows Installer Formatted Type article.

Hope this helps! If you have any other questions, please don’t hesitate to contact us.

Best regards,

Hi! Thanks for your reply. Maybe you mean to set properties like this way?

I have try also in this way and it seems that the property inside '[]' are not replaced with value at runtime. I have used that properties in XML configuration files and it just simply puts '[ROOT_PATH]\Configuration'

I supuse that the only way is using custom actions?

This happens because the value field of a property does not support Formatted data types properties.

To update the property in this way, you will need a Set installer property custom action.

Hope this helps!

Thanks for your help! This is what I have done. What is the recommended stage to put this type of actions?

Hello,

You can add these custom actions before the Path Resolution standard action under the Wizard Dialogs Stage in the Custom Actions page.

Let us know if you have any other questions.
