This are my first steps with the QuickPDF Library.

I use the SetFormFieldValueByTitle() function in VB6 to insert text in text fields (Fieldtype 1).

The inserted text is not displayed in Adobe Reader.

I just load the pdf-document with LoadFromFile(fileName, ""), fill in the fields with SetFormFieldValueByTitle() and save a new file with SaveToFile.

Opera Internet Browser shows the inserted text, why Adobe not?

Thanks in advance for a hint.

Hi Skandinavier ;-)

here you'll find a complete sample from Kevin (R.I.P):

UpdateAppearanceStream will be your key i think ;-)
Here's a good starting point for search deeper:

Hi Ingo,

Thank you for your answer.

I tried the function - with no success. But that's not my biggest problem. The PDF form that I populate with text also has two signature fields (Fieldtype 6). It looks like all properties of a signature in the signature fields have been lost in the new file (saved with SaveToFile). Is there a possibility to save the signature fields unchanged?

Greetings

Please read 3.2.12 in the developer guide "Processing digitally signed PDF files".
Perhaps this will help.

Regarding your issue:
"It doesn't work" isn't a really detailed answer ;-)
Where's the sample pdf? You can upload it anywhere on a free file hoster or on your website and post the link in the forum...
Where's the relevant code snippet from your development?

Cheers,
Ingo

Hi Ingo,

Thank you for your efforts.

I have uploaded the files:

https://github.com/MailiEder/App-development

The original template:

Arbeitsauftrag-GmbH.pdf

The generated file:

Arbeitsauftrag_Test_1.pdf

Code:

Vb6code.txt

Adobe Acrobat Reader DC

The inserted text is not displayed. A signature can be entered in the signature fields.

Perfect PDF 9 (Soft Xpansion)

The inserted text is displayed. But a signature cannot be entered in the signature fields.

If you try to enter the signature, this message comes up:

This form field (signature) still has to be filled out.

All i want is:The inserted text should always be displayed and the signature fields should remain untouched. The document should - in practice - be read and signed on a tablet.
