wPDFControl lets you create PDF files from your VC, VB or VBS project. It comes with an OCX which acts as an optional interface and a DLL. Many programming languages allow you to load the DLL directly in this case the OCX
is not required.

　　The DLL comes with an ActiveX which serves to load the PDF engine DLL and provides an interface to it. The ActiveX can be used in languages such as Visual Basic, where it is difficult to use the callback function required for the PDF engine. We do not recommend using the ActiveX in C or other languages which allow callback procedures to be defined.

　　To use PDFControl in your application you first have to load the DLL and initialize it. We have created a header file which makes it easy to do this in C and have also provided a C++ class which does most of the tasks automatically.

　　We do not recommend static binding since this would cause errors if the DLL is not found. After you have initialized the DLL you can execute the function to start the output.

　　.NET support wrapper - developed in C# and uses properties, flags, events, streams．
