Delphi Code - Open a Password Protected Word File and Save As
Here is a simple Delphi procedure that opens an existing password protected Microsoft Word file (i.e., Word document), adds some text to the file, saves the file with a new name (save as), and finally closes the file. In addition to the file name and password, a number of optional parameters may be passed to open the Word file. 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.OpenAPasswordProtectedWordFileAndSaveAs(Sender: TObject);
var
WordFileName, WordFileNameNew, Password: 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
WordFileNameNew := 'C:\PhysiologyWeb\delphi_code_examples\word_file_new.docx'; //replace file name with the name of your file
Password := 'physiologyweb'; //replace with password of your file

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, EmptyParam, EmptyParam, EmptyParam, Password, EmptyParam, EmptyParam, EmptyParam, EmptyParam, EmptyParam);
//reference

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

If VarIsNull(WordFile) = False then
begin
//add some text to the new Word file
WordFile.Range.Text := 'Adding this sentence to the password protected Word file.';
//reference
//https://docs.microsoft.com/en-us/office/vba/api/word.range.text

WordFile.SaveAs(WordFileNameNew);
//reference

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

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