Initializing a PDF Reader control

• Define the initial document ("General" tab in the control description window).
• Assign the PDF file to the PDF Reader control. For example:
  

  // Selects a .pdf file in the current directory
  sFileName is string
  sFileName = fSelect("", "Presentation.pdf", ...
  	"Selection of PDF files", ...
  	"Pdf file (*.pdf)" + TAB + "*.pdf", "*.pdf", fselOpen)
  
  IF sFileName ~="" THEN
  	// No selected file
  	RETURN
  END
  
  // Load PDF file
  PDF_MyDocument = sFileName

  If passwords are used:
  • If the file is password-protected, a window will appear to enter the password.
  • It is not possible to open a protected PDF file.

• Use the <PDF Reader>.Open function. For example:
  

  PDF_MyDocument.Open("C:\Users\test\Documents\file.pdf")
  
  IF ErrorOccurred() THEN
  	Error(ErrorInfo())
  	RETURN
  END

  Note: The <PDF Reader>.Open function allows you to program the file password.
