Install & Uninstall

[deepak407]

Hi

Do we have any Built in Install And Uninstall functions (Like OnBegin & OnEnd )?

When I am using OnBegin Function ,it is called at the time of installation and UnInstillation.

Can anybody provide an example?

List of built in functions in IS 2010?

In InstallScript, the MAINTENANCE variable is FALSE for a first-time installation, and TRUE for maintenance mode or uninstallation. Therefore, you can use an if statement like the following for any code you want to run only for a first-time installation.

if (!MAINTENANCE) then 
    // code to run for first-time installation 
endif;

You can use that sort of code in event-driven InstallScript code of InstallScript and InstallScript MSI projects.

I hope that helps.
