Amyuni PDF Converter version 3.03
PowerBuilder 10.2.1
EAServer 5.5
--------------------
Hi,
I am trying to generate a single PDF from two PDFs previously generated by Amyuni PDF Converter, using the DLL.
I have a Powerbuilder NVO component that reside in EAServer with the following local external function declared as:
Function boolean ConcatenateFiles( string inputFile1, string inputFile2, string outputFile) LIBRARY "cdintf300.dll"
I am trying to concatenate using the Amyuni ConcatenatFile function with logic bellow but it always returns false. I've
included a summary of the events and methods I'm using. I've tried numerous scenarios to no avail. Any help would be appreciated!
Thanks
Eric

ls_concatenated_file_output = "c:\consolidate\output.pdf"

Problem using ConcatenateFiles
Re: Problem using ConcatenateFiles
Hello,
I am not sure why you are calling Lock() and Unlock() functions.
You just need to call 1 function: ConcatenateFiles(File1, File2,File3).
File1 and File2 should be pdf files already existing in the system (not being generated in the process). File3 is the output file.

Re: Problem using ConcatenateFiles
Hi Joan,
Thanks for replying.
I removed the Lock and Unlock from within my of_lock and of_unlock methods. I still left the SetDocFileProps with the Concatenate option. My latest try still returns false. Does the output file need to exist in advance?
We have been using AMYUNI PDF Converter for 4 or 5 years with success and I was trying to use the concatenation to resolve a situations within our web app where multiple PDFs are created and need to be merged together.
Thanks for your time,
Eric

Re: Problem using ConcatenateFiles
SetDocFileProps() is used only with the locking mechanisme (i.e while using Lock() and Unlock() functions).
Please try to remove it and use instead: SetFileNameOptions() and UseFileName()
You mentioned that your code has been working for 4-5 years now, were you using the locking functions or you add these lately?
Please note that another option would be to call the ConcantenateFiles() function in a totally different routine than the one where you are generating the pdf files.Whidh is advisable by the way. After generating the pdf files and having them on disk you can call ConcantenateFiles() only.
Hope this helps.
