Flattening File Doesn't Work

[mcwagner_nro]

I am attempting to flatten fields in Spire.PDF.

However, the method provided in the examples doesn't actually flatten the file.

In fact, when I attempt save the file that I set "isFlatten = true" I get an error:

"Please wait... If this message is not replaced by the contents of the file..."

Any ideas?

Thanks for the replay.

I updated the .ddls to no avail.

I can open a saved .pdf but setting pdfDOc.form.isflatten = true doesn't result in a flattened PDF file.

Having the same issue here with the latest 8.9.2 verion of spire pdf dll. Old version flattened the IRS form just fine, but now it will not. Same form will flatten ok if I use Adobe. Please advise.
