Hello Everybody !

I downloaded the trial version and am trying to understand the "Hello World" sample (DLL).

I am starting debugging under Visual Studio and I am getting an unhandled exception when executing :

result = QuickPDFLibraryVersion(instanceID);

Could you help me ?

It might be helpful to look at the complete code you are using before you get to the point where you get the error. I use the Delphi version so I don't know if you need to create the QuickPDF object that you are calling, but that is a possibility. I don't think you will get a valid result if you don't use the unlock procedure before you call any functions.

We might think that the sample would be ready to use ...

The code is :

// Declare and load Quick PDF Library DLL

QuickPDFDLL0717 QP("C:\\Program Files\\Quick PDF Library\DLL\\QuickPDFDLL0717.dll");

// Library key

// std::string strLicenseKey = "INSERT LICENSE KEY HERE";

std::string strLicenseKey = "Your_Key";

// PDF output filename

std::string strFileName = "hello-world.pdf";

// Display message containing the library version

std::string strMessage = ("Quick PDF Library Hello World sample");

strMessage.append("\n");

strMessage.append("Library version: " + QP.LibraryVersion());

Make sure that you actually have version 7.17 installed at "C:\\Program Files\\Quick PDF Library\DLL\\QuickPDFDLL0717.dll" and not version 7.18 or 7.19. Update your code based on which version you have installed. My guess is that the error is the result of the sample using a different version to the one you have installed.

You're right. I installed the version 7.18
