PrintDialog() Method

In This Topic
Invokes the standard Windows Print dialog box, which allows you to select additional options or settings and then to print the currently loaded PDF document.
Syntax
'Declaration

 


Public Overloads Function PrintDialog() As Boolean
public bool PrintDialog()
public function PrintDialog(): Boolean; 
public function PrintDialog() : boolean;
public: bool PrintDialog(); 
public:

bool PrintDialog();

Return Value

true if the method has been followed successfully, otherwise false. Please use the PrintGetStat method to determine the reason for the printing failure.
Remarks
It is recommend to use the GetStat method or the PrintGetStat method to identify the specific reason for the method's failure, if any.

You also need to be aware that annotations and form fields included in the document are rendered by default using this method when printing.

Just to inform you, that sometimes pages in the PDF document may have defined their internal rotation, which causes them to be unexpectedly rotated when printing. Then you need to use the NormalizePage method for each such page to remove that rotation. You can also use the GetPageRotation method to find out if the page should be rotated when printed.
