Hi,

I'm adding the ability to an application to output reports to PDF. Current that application only outputs to a printer using to standard GDI functions. To implement this, I've changed the printing code to create wrappers for the GDI Print API functions StartDoc, EndDoc, StartPage, EndPage. When printing to a to printer, the wrappers behave as expected but when outputting to a PDF file, they call QuickPDF library functions. The document is created but with only the first page. Here is the sequences of QuickPDF calls:

QP.GetCanvasDC(10200, 13200); // initialization
// GDI operations on Canvas DC for first page
QP.LoadFromCanvasDC(1200.0, 3); // called on first EndPage invocation
// GDI operations on Canvas DC for second page
QP.NewPageFromCanvasDC(1200.0, 3); // called on subsequent EndPage invocation
QP.SaveToFile("Report.pdf"); // called on EndDoc invocation

I should note that the call to NewPageFromCanvasDC fails which leads me to believe this is the wrong sequence of functions or that I'm missing some function calls to do what I need to do.

Any ideas? Thanks,
