Hello :)

I know there are Libs were you can create a PDF file.
But is it possible to write into an exitsing PDF File (an PDF Formular which has Fields in it)

in Vb.net it is possible to create an copie of the PDF file which looks the same as the Original PDF file and
you can write into the fields (textboxes of the file). Is this possible with B4A?

Regards

I don´t know any Library for this.

There are many java libraries out there but all (or most) of them are paid.

Yes, there are, i wrapped a library for this years ago, i will look for it and upload it, these forms are called AcroForms, the library basically takes the already made PDF file and reads the fields in the form and you can basically write content to each field, once the form is filled out the form gets flattened and you are able to open it with the regular methods and see the filled out form.

I will look for the library and upload it when i get a chance.

ok, that would be great.
In the meantime you can play with this quickanddirty little wrap.

Download the PDFBox jars here: https://www.dropbox.com/s/1wh9ldpumahqks5/AddLibsPDFBox.zip?dl=0

Samplecode

B4X:
    Wait For (File.CopyAsync(File.DirAssets, "acroform1.pdf", File.DirData("PDFBox"), "acroform1.pdf")) Complete (Success As Boolean)
    Log("Success: " & Success)
    box.Initialize("",File.Combine(File.DirData("PDFBox"),"acroform1.pdf"))
    box.setField("Here we have a form field","B4X rules!")
    box.setField("Just try to enter something into this field","B4X rules again ;-)")
    box.save(File.Combine(File.DirData("PDFBox"),"acroform_neu.pdf"))
