Hello,
i have a problem appending pdfs to another pdf. the main problem is , there is no split function to split a pdf exactly (example: split page 1-5 and page 5-10 etc.). so i use the pdfsplit.exe utility to make a 10 page pdf to 10 single pdfs and append them to my own needs. Everything with the PDF Creator ActiveX interface
The problem: in Debug (when i walk through) everything is fine. (i created my self concatenated PDFs.) In Release or without stepping through the programm the result after Save is a blank page. So i have to assume its a timing problem (functions are in a thread??) and added sleep(100) after every step an it works. No blank pages.
Is there another way ? finish messages ?
We use native C to access the activeX because of an exotic programming language:
...
// its only Open the PDF sTmpPath
InvokeHelp(lpDispatchPDF, 0x17, DISPATCH_METHOD, VT_I4, (void*)&nResult, parms2, sMainPath, "");
Sleep(100)
...
// Append another PDF sTmpPath to the opened pdf
InvokeHelp(lpDispatchPDF, 0x56, DISPATCH_METHOD, VT_EMPTY, NULL, parms3, sanotherPDF, "");
Sleep(100)
...
// Save
InvokeHelp(lpDispatchPDF, 0x16, DISPATCH_METHOD, VT_EMPTY, NULL, parms4, sNewPDF, 0);
Sleep(100)
...
// release everything and exit
lpDispatchPDF->Release();
...

Blank Pages after append pdf to a pdf
Hello,
In general you won't need to add a time delay after the Append function, I am not sure what do you mean by: "function are in a thread", is your application multithreading?
You may try to get the return value of the Open and Append functions, if True is returned than you call the next function.
Hope this helps.
