Hi,

We are evaluating the QUICKPDF with PowerBuilder 10.5. I have written a piece of code to test the pdf merge functionality

Long ll_instance, ll_ret

ll_instance = QuickPDFCreateLibraryA()
ll_ret = QuickPDFUnlockKey(ll_instance, 'j57g79ru43q3xz8su8wu3ej8y')

if ll_ret = 1 then //
                ll_ret = QuickPDFAddToFileListA(ll_instance, 'List', 'one.pdf')
                 ll_ret = QuickPDFAddToFileListA(ll_instance, 'List', 'two.pdf')
                ll_ret= QuickPDFMergeFileList(ll_instance, 'List', 'three.pdf')
End if

I am not able to get return value 1 (ll_ret = 1) in the unlockkey function. COuld you please help to overcome from this issue.

Thanks and regards,

Ram

PowerBuilder uses AnsiStrings and Quick PDF Library defaults to Unicode strings.

We have added a set of 'A' functions to QPL to allow passing and returning of Ansi strings

So instead of calling :-

QuickPDFUnlockKey you call QuickPDFUnlockA

Also

QuickPDFLoadFromFileA

QuickPDFRenderPageToFileA

QuickPDFMergeFileListA

...

Every QPL function that uses a string has a matching A function.

Long ll_instance, ll_ret

ll_instance = QuickPDFCreateLibrary() // <<
ll_ret = QuickPDFUnlockKeyA(ll_instance, 'j57g79ru43q3xz8su8wu3ej8y') // <<

if ll_ret = 1 then //
                ll_ret = QuickPDFAddToFileListA(ll_instance, 'List', 'one.pdf')
                 ll_ret = QuickPDFAddToFileListA(ll_instance, 'List', 'two.pdf')
                ll_ret= QuickPDFMergeFileListA(ll_instance, 'List', 'three.pdf') // <<
End if

Andrew.

Hi Andrew

Thanks very much for sharing the tips to resolve the problem. It is working perfectly fine now. Is there any tips to create bookmarks inside the PDF's (like clicking on the master row should take me to detail rows in the same pdf document ). I am trying to incorporate linkage chain between master and detail records like we are doing inside the Datawindow linkage.

I really appreciate your timely help

Thanks and regards,

Ram

Ram,

Andrew is correct about Powerbuilder. Powerbuilder 10.5 does indeed use Ansi strings. BUT, if you upgrade to Powerbuilder 11.0 or greater, Powerbuilder then uses wide character (or sometimes called Unicode) strings. So depending on what functions you call you may have to change your code to accommodate Powerbuilder's internal changes.

Just a little warning
