Introduction - If you have any usage issues, please Google them yourself
I ve been using Port95NT s DlPortIO.dll to read/write bits to my parallel port for many years with C++ by using the associated DlPortIO.lib and a custom wrapper class. Since I ve moved to (mostly) C#, I wanted to create a managed assembly to standardize the interface to DlPortIO.dll. I started by using the DllImport attribute, then for kicks took a left turn into exploring the use of the .lib that comes with the DLL.
