   LoadFromFile('file name') --> returns 1
   ReplaceTag('something','something else') --> returns 0 although string   
                                                      'something' exists in source document.

	Hi! What you wanna do you can do with ReplaceTag but ... Please keep in mind that this functionality doesn't work on all pdf-documents. It won't work for example on documents with LZW-compression. If your documents are encrypted then the text you're looking for is encrypted, too. In this case you have to encrypt the document before you're using ReplaceTag: If QP.Encrypted > 0 Then QP.Unencrypt; It should be clear that after ReplaceTag you've done a save and new load?

	I can't found "Encrypted" and "Unecrypt" I found "EncriptionStatus" and "Decrypt". Is that the same ? MfG, Dejan

	Hi Dejan! You're "eagle eye" ;-) It seems to me that Debenu has forgotten these important two functions while rewriting the new documentation. They are reading here, too - so i'm pretty sure that there's a new documentation available soon. Here's a part of the old documentation: Encrypted ========= Description ----------- Determines the encryption status of the selected document. Definition ---------- Function Encrypted() As Long Parameters ---------- N/A Returns ------- 0 The selected document is not encrypted. 1 The document is encrypted with Adobe "Standard" encryption. 2 The document is encrypted with an unknown encryption Unencrypt ========= Description ----------- Attempts to decrypt the selected document. If the document is encrypted and the user password has been set, then the SetPassword function must be called before this function. Definition ---------- Function Unencrypt() As Long Parameters ---------- N/A Returns ------- 0 The document could not be decrypted. 1 The document was decrypted successfully.

	Hi Guys, Sorry for the confusion -- but the two functions, Encrypted and Unencrypt, were renamed in version 7.12 to be EncryptionStatus and Decrypt. The new function names provide a more accurate description of the functionality. A full list of renamed functions can be found here: http://www.quickpdflibrary.com/help/quickpdf/RenamedFunctions.php Cheers, - Rowan.

	This doesn't work: with PDFLibrary1 do begin LoadFromFile('c:\test.pdf'); if EncryptionStatus > 0 then begin Decrypt; end; ReplaceTag('R','P'); SaveToFile('c:\changed.pdf'); end; file is not encripted (EncriptStatus = 0) What am I doing wrong ? I must replace some variables in PDF file with data from database. Is there another way to do it ? Edited by dejan61 - 17 Apr 09 at 2:53AM

	Hi! What do you mean with "replace variables"? If you want to change values from formfields then you should use the functions from the section "form fields". Cheers, Ingo

	I must insert data from databes into pdf document: Tekst in PDF document: Name: <Name> The program must replace the text <Name> with the data from database. Result will be: Name: Dejan How can I do this the other way ?

	Hi Dejan! What you wanna do is like closing the eyes to the options the pdf-specs are offering to you ;-) You should create a normal pdf-template with formfields. This formfields you can fill then without any problem and after you've flatten the values they'll stay in the pdf. So my advice: Forget the way you wanna go and do it with formfields. That's the better (standard) way. Cheers, Ingo
