问题
so I know you can add a custom field with the .add method...is there any way to REMOVE one?
The reason is I'm only adding the fields if a component is selected, and if the user goes back I want to remove the fields, so that they don't multiply. :)
Thanks!
Here's my .iss: (I was planning to put the code in the OnBackButtonClick function...that's why it's there ;)

回答1:
As you're using CreateInputDirPage(), the page is a TInputDirWizardPage. When you call .Add() it returns an index that you can use with the page's .Buttons[index], .Edits[index], and .PromptLabels[index] properties to get direct access to the controls themselves.
This then allows you to to set .Visible or .Enabled directly:
DataDirPage.PromptLabels[IndexToDisable].Enabled := false; DataDirPage.Edits[IndexToDisable].Enabled := false; DataDirPage.Buttons[IndexToDisable].Enabled := false;
The far better alternative though if there are more differences is to have two pages, and just skip one or the other in the ShouldSkipPage() event function.
