| Name | Type | Description |

| stream | Stream |
A Stream object.

The PDF Document API component expects that the input stream will not be modified or closed before the component finishes using a document. Call the PdfDocumentProcessor.LoadDocument(String, Boolean) method overload to force the PDF Document API component to complete all input operations after loading a document.
If the PdfProcessor fails to load the document, an ArgumentException is thrown.
The code sample below uses PdfFormData to set form field values:
// Load a document with an interactive form.
using (PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor()) {
documentProcessor.LoadDocument(filePath + fileName + ".pdf");
// Obtain interactive form data from a document.
PdfFormData formData = documentProcessor.GetFormData();
// Specify the value for FirstName and LastName text boxes.
formData["FirstName"].Value = "Janet";
formData["LastName"].Value = "Leverling";
// Specify the value for the Gender radio group.
formData["Gender"].Value = "Female";
// Specify the check box checked appearance name.
formData["Check"].Value = "Yes";
// Specify values for the Category list box.
formData["Category"].Value = new string[] { "Entertainment", "Meals", "Morale" };
// Obtain data from the Address form field and specify values for Address child form fields.
PdfFormData address = formData["Address"];
// Specify the value for the Country combo box.
address["Country"].Value = "United States";
// Specify the value for City and Address text boxes.
address["City"].Value = "California";
address["Address"].Value = "20 Maple Avenue";
// Apply data to the interactive form.
documentProcessor.ApplyFormData(formData);
// Save the modified document.
documentProcessor.SaveDocument(filePath + fileName + "_new.pdf");
}
' Load a document with an interactive form.
Using documentProcessor As New PdfDocumentProcessor()
documentProcessor.LoadDocument(filePath & fileName & ".pdf")
' Obtain interactive form data from a document.
Dim formData As PdfFormData = documentProcessor.GetFormData()
' Specify the value for FirstName and LastName text boxes.
formData("FirstName").Value = "Janet"
formData("LastName").Value = "Leverling"
' Specify the value for the Gender radio group.
formData("Gender").Value = "Female"
' Specify the check box checked appearance name.
formData("Check").Value = "Yes"
' Specify values for the Category list box.
formData("Category").Value = New String() { "Entertainment", "Meals", "Morale" }
' Obtain data from the Address form field and specify values for Address child form fields.
Dim address As PdfFormData = formData("Address")
' Specify the value for the Country combo box.
address("Country").Value = "United States"
' Specify the value for City and Address text boxes.
address("City").Value = "California"
address("Address").Value = "20 Maple Avenue"
' Apply data to the interactive form.
documentProcessor.ApplyFormData(formData)
' Save the modified document.
documentProcessor.SaveDocument(filePath & fileName & "_new.pdf")
