WIX - Spawning a Dialog dialog during installation

Is it possible to spawn a dialog after a custom action that is scheduled in InstallExecuteSequence???

I have a two custom 开发者_运维知识库Action, after the first one, I need to spawn a dialog. When the user click OK on that dialog, the dialog close and continue the second one.

But how can I spawn that dialog after the custom action is done??

May not be exactly what you are looking for, but in your custom Action, if you include System.Windows.Forms you can call MessageBox.Show("...") to bring up a dialog.
