	Hi! Has anybody used the function SaveToString from DLL? What I experience is that I only get the first 768 byte of the document. Can anyone tell me how to make it work? Thanks in advance. Regards, Jan

	Hi Jan! Without looking into the function this moment ... Perhaps the read-in-loop is the problem? Normally such loop begins with "...until eof...". If i look inside pdf-files with notepad i often see the eof-sign anywhere inside (not at the end!) of the pdf-content. Perhaps SaveToStr stops at this eof? Best regards, Ingo

	Hi Ingo! Unfortunately the break is not that clear. The returned string ends in between a pdf stream object: .... >> startxref 0 %%EOF 9 0 obj << /Type /Catalog /Pages 10 0 R >> endobj 10 0 obj << /Type /Pages /Kids [ 11 0 R 1 0 R ] /Count 2 >> endobj 20 0 obj << /Length 21 0 R /S 46 /Filter /FlateDecode >> stream x�c```c``Z�� .� �� Could it be that this somehow is a limitation of Delphi when using DLLs!?

	Probably useful information: I'm using Delphi 7.

	Hi there, do not use that function. Because of string manipulations you may get truncated in the wrong place. You should use instead the last ActiveX version toghether with SaveToStream function. Best regards, Marian
