Examples

The following code example demonstrates the PrintPreviewDialog setting the Document and UseAntiAlias properties. The example assumes the form contains a TreeView named TreeView1 that contains TreeNode objects. The Tag property of each TreeNode object must be set to a fully qualified document name that can be accessed by the machine running the example. Set each TreeNode.Text property to a string that identifies the file specified by the TreeNode.Tag property. For example, you could set TreeNode1.Tag to "c:\myDocuments\recipe.doc" and TreeNode1.Text to "recipe.doc". The example also assumes the form contains a PrintPreviewDialog named PrintPreviewDialog1 and a button named Button1. To run this example, call the InitializePrintPreviewDialog method in the form's constructor or Load event handler.
