PrintPreviewDialog Constructor ()
Initializes a new instance of the PrintPreviewDialog class.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When you create an instance of PrintPreviewDialog, the Document property is initialized to null. You can change the value for this property at run time.
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.
