Hi folks,

I'm just testing out the trial version of QuickPDF library.
I've got the dll version working perfectly in C# winforms but for some reason in a C# WPF project the function qp.UnlockKey() always returns 0. Does QuickPDF library work correctly under WPF?
I assumed it would work in exactly the same way as in the winform version.

In the code snippet below, the msgbox "License unlock failed." is always displayed in a WPF project.

Any help you can provide would be much appreciated.

PDFLibrary qp = new PDFLibrary(@"C:\Program Files (x86)\Quick PDF Library\DLL\QuickPDF64DLL0816.dll");

qp.UnlockKey("My trial key");
            if (qp.Unlocked() == 0)
                MessageBox.Show("License unlock failed.  Please update your key in the form1.cs source code");

Doh. stupid noob mistake.
I was referencing the 64 bit DLL in a 32 bit project.
