AskThumbnails, VIRTUAL, PROTECTED
The AskThumbnails method prompts the end user for the number of pages to tile across and down the preview window.
Implementation:
The PrintPreviewClass.Display method calls the AskThumbnails method. The AskThumbnails method displays a dialog that prompts for the number of thumbnails to display horizontally, and the number of thumbnails to display vertically.
Example:
