Delphi Code - Print Microsoft Word File to Adobe PDF
Here is a simple Delphi procedure that opens an existing Microsoft Word file, and saves the file as a PDF file by printing the file to Adobe PDF. The code then closes the Word file. No changes are made to the Word file before saving in PDF format. The most relevant parts of the code are highlighted. Comments are included to explain the code. If you copy and paste the code into your program, be sure to change the form and procedure names to match your setup. For additional Word automation solutions, see Microsoft Word Automation with Delphi.
procedure TForm1.PrintMicrosoftWordFileToAdobePDF(Sender: TObject);
var
WordFileName, PDFFileName: String;
WordApplication, WordFile: Variant;
begin
//be sure ComObj and Variants units are included in the "uses" clause

WordFileName := 'C:\PhysiologyWeb\delphi_code_examples\word_file.docx'; //replace file name with the name of your file
PDFFileName := ChangeFileExt(WordFileName, '.pdf');

WordApplication := Null;
WordFile := Null;

try
//create Word OLE
WordApplication := CreateOleObject('Word.Application');
except
WordApplication := Null;
//add error/exception handling code as desired
end;

If VarIsNull(WordApplication) = False then
begin
try
WordApplication.Visible := True; //set to False if you do not want to see the activity in the background
WordApplication.DisplayAlerts := False; //ensures message dialogs do not interrupt the flow of your automation process. May be helpful to set to True during testing and debugging.

//Open Word File
try
WordFile := WordApplication.Documents.Open(WordFileName);

except
WordFile := Null;
//add error/exception handling code as desired
end;

If VarIsNull(WordFile) = False then
begin
WordFile.ExportAsFixedFormat(PDFFileName, 17, False, 0, 0); //wdExportFormatPDF = 17
//If a file with the new name already exists, it overwrites it. Write additional code to address as desired.
//parameters:
//Name Required/Optional Data type Description
//OutputFileName Required String The path and file name of the new PDF or XPS file.
//ExportFormat Required WdExportFormat Specifies either PDF or XPS format. wdExportFormatPDF = 17; wdExportFormatXPS = 18
//OpenAfterExport Optional Boolean Opens the new file after exporting the contents.
//OptimizeFor Optional WdExportOptimizeFor Specifies whether to optimize for screen or print. wdExportOptimizeForPrint = 0; wdExportOptimizeForOnScreen = 1
//Range Optional WdExportRange Specifies whether the export range is the entire document (0), the current page (2), a range of text (3), or the current selection (1). The default is to export the entire document.
//see reference below for additional optional parameters

finally
WordFile.Close;
WordApplication.DisplayAlerts := True;
WordApplication.Quit;

WordFile := Unassigned;
WordApplication := Unassigned;
end;
