H8i,
Ahhh. But the PDF you sent me has 5 pages in it. Which means that your lines
c1->Print("h1.pdf(");
c1->Print("h1.pdf)");
add to the file. I *specially* do not want this. I want to completely decouple the actions of opening and closing the file from filling it. This is why I am using the "[" and "]" syntax. I.e.
c1->Print("h1.pdf["); // Open the file without adding a page c1->Print("h1.pdf"); // add a page c1->Print("h1.pdf"); // add a page c1->Print("h1.pdf"); // add a page c1->Print("h1.pdf]"); // close the file without adding a page
so I end up with a PDF with only 3 pages.
Am I misreading the documentation for how the "[" and "]" syntax is supposed to work ?
cheers Chris
