User Input during UnInstall

[abby27]

Hello,
I have a basic MSI project and Installation works fine.
During Uninstall, I need to collect some user input, such as option to remove SQL database etc.., by providing some options in a Dialog Box.

I have 2 questions

1) Can someone show, how to do this? (I know how to create a Custom Dialog)
ie) how to display this Dialog during UnInstallation

2) During installation, in one of my wizard steps, when the user clicks the 'Next' button my installer executes a long running process Custom Action. At this time, I would like to display a Message "Processing...please wait..." in a dialog box(without the minimize/maximize toolbar buttons). How can this be done. Please provide an example

Thanks in advance for your help

You can use SdShowMsg("Processing...please wait..", TRUE) for displaying the message. You will have to call this again with "FALSE" as the 2nd parameter when you want to stop displaying the message.

Thanks for the solution. But, mine is a Basic MSI Project. Do you have a solution for Basic MSI?

For Basic MSI, if a user clicks Remove in Add or Remove Programs, only the Execute sequence runs; if you must show a user interface during uninstallation, perhaps disable the Remove button?
