Repeating screens during setup

[DanKerns]

Is it possible to programatically control what order screens appear in during a setup?

I've got a screen where the users enter certain information (an edit boxes screen). In an "After action" I validate the data the user typed. When the data is invalid, I want to present a Message Box describing the error and then show the screen again so the user can correct the input.

How can I do this?

Thanks,

Dan

Hi Dan,

First make sure you are using the latest build 6.0.1.2.

The following information was taken from the Setup Factory 6.0 Command Reference which should answer your question:

%PreventNextPage%
This is a special variable that can be set on a screen's Before or After action tabs. If this variable is set to TRUE, the installer will not allow the user to proceed to the next screen when the Next button is clicked; instead, the user will remain on the current screen. If set to FALSE, the installer will allow the user to proceed normally when they click Next.

This variable is useful if you want to validate the data entered by the user on a screen. If the data is incorrect, you could display an error message and set %PreventNextPage% to "true" to make the user go back and enter valid data.

The value of %PreventNextPage% is reset to FALSE every time a screen is displayed.

Thanks. That works great.

Is there any way to get rid of the "Displaying Dialog" dialog that appears when a message box is on the screen?

For that you could use the following built-in variable:

%ShowActionProgressDlg%
This variable controls whether or not the Action Progress dialog is visible. If this variable is set to TRUE, the Action Progress dialog will be visible. If it's set to FALSE, the Action Progress dialog won't be visible.

Note: This variable has no affect during the uninstall.

Thanks. I tried that and the dialog didn't go away.

I tried setting as both before and after actions on the screen and as a before installing action in the project.

Any thoughts?

I just did a test and didn't have any problems.
I placed the Assign Value action to set %ShowActionProgressDlg% to FALSE on the Before actions tab, and then the other actions on the AFTER actions tab of the screen. Are you using 6.0.1.2?

Re: Repeating screens during setup

That's exactly what I am doing. In my after handler I display a message box and I see this weird dialog. I've included a screen shot.

I am using 6.0.1.2 evaluation.

If you're still having problems, send your project file(.sf6) to [email protected] and I'll take a look.

Make sure that you haven't made any spelling mistakes when assigning your value to the built-in variable.
