I am using Delphi and QuickPDF v 7.21 and I'm having problems viewing filled forms. Basically I am doing the following:

APDF.LoadFromFile( 'Form.pdf' );

APDF.SetFormFieldValue( 1, 'Test' );

APDF.RenderPageToFile( 72, 1, 5, 'Filled.png' );

// Code to View 'Filled.png'

That only shows the form without any fields filled in. As a test, I added:

APDF.SaveToFile( 'Filled.pdf');

and compared 'Filled.png' with 'Filled.pdf'. 'Filled.pdf' has the fields correctly filled in while 'Filled.png' does not. So I am relatively confident that I am filling the form correctly. I also inspected the results of each command and everything indicates success.

I then modified my code as follows:

APDF.LoadFromFile( 'Form.pdf' );

APDF.SetFormFieldValue( 1, 'Test' );

APDF.FlattenFormField( 1 );

APDF.RenderPageToFile( 72, 1, 5, 'Filled.png' );

// Code to View 'Filled.png'

Flattening the Field first resolves the problem. Flattening the Field, however complicates my code since after viewing I may need to go back and Set the field to a different value.

Is there a way set the field value and render the page for my viewer without Flattening? TIA.

Hi Luke!

Instead of Flatten you should use SetNeedAppearances ...
Then it will work as you want it to.
