InpOut32 is an open source windows DLL and Driver to give direct access to hardware ports (for example the parallel and serial port from user level programs. It is originally developed by the people at Logix4U for Windows 9x and 32bit variations of NT (NT/2000/XP/2003 etc.). I have ported the original code (written by Logix4U) it to Windows XP 64bit Edition (XP/2003/Vista/7/8/8.1 x64 Editions) because the 32bit driver will not install or run on x64 systems. My new version supports both 32bit and 64bit systems running under WOW64 as 32bit applications, and with a new x64 DLL, pure x64 applications.

'hello, i want to interface parallel port in Visual Basics 6.0. For that i will have to register inpout32.dll into my system. So when i registered this file into my system it cant be regestered and diplay message like this,'inpout32.dll was loaded, but DllRegisterServer entry point was not found. So this file cant be registered.'

My port of InpOut32 supports both 32bit and 64bit systems running under WOW64 as 32bit applications, and with a new x64 DLL, pure x64 applications. I am pleased to say that InpOutx64 now fully supports Windows Vista, 7 and 8.1 x64, allowing you to easily run any application designed to run with InpOut32 on Windows Vista+ and Server 2008+ x64 editions. Many thanks to Warren at Red Fox UK for signing the drivers that allow all this to work on all current Windows operating systems. Installation of InpOut32: For end users: If an application has been written to make use of InpOut32.dll then all you need to do is place my version of InpOut32.dll in the same folder as the 'original'.

This would usually be the same folder as the applications EXEcutable file. Most applications use the 32bit version of the DLL. This version is still capable of installing and running on x64 based operating systems, but the first time it is run, it must be elevated on Vista and later (run as Administrator). Included in the binary download is a small 'InstallDriver.exe' program to do this for you. Radiant keygen software license. For developers: The driver (.sys file) is included, as a resource in the DLL. All you need to do is link to the appropriate DLL in your program and it should work.

NOTE: When the DLL loads for the first time, the appropriate driver is installed and used. NOTE: Elevated permissions are required in Vista and later to install the driver.

S I recommend using runtime linking to the C interface (manually loading the library) in C++, in much the same as the interop calls from.NET work. However you can also use the.LIB and header files provided to link at compile time if that suits your application better. Development: There are examples and usage instructions for the 32bit version on the original author's site Logix4u (note I have removed links as they reportidly no longer active and their site appears to have been impacted by malware) and below in the download links. To use the 64bit (x64) port (from a 64bit application), all you need to do, is use my x64 compatible DLL called InpOutx64.DLL, either using InpOutx64.lib or runtime linking (LoadLibrary, GetProcAddress etc.). Everything else is the same as the 32bit (InpOut32) DLL. Please bear in mind, that on 64bit operating systems, many applications are still 32bit. If your application is 32bit you MUST use my version of InpOut32.dll which contains both 32bit and 64bit drivers and determines which one to install and use at runtime.

If your application is 64bit (x64) then use InpOutx64.dll. Both DLL's can install and talk to the 64bit (x64) driver on x64 editions of Windows. NOTE: Because I used Visual Studio 2005 to build the DLL's you may need the 2005 SP1 Microsoft C++ Runtimes. These should be available from Microsoft. You will have them if you have Visual Studio 2005. If you can’t find them, send me an email! Update History: The initial build (DLL v1.0.0.1) I created didn't work properly in x64 because it still installed the 32bit driver (and called it hwinterfacex64.sys) oops!

It was possible to use it by replacing the driver.sys file with the real hwinterfacex64 (included) but this was not the intended method of installation! The build v1.0.0.2 (dated ) should work properly on both OS types. UPDATE: () 32bit DLL for 1.0.0.2 does not work on x64 windows:( I am currently working on a fully functional 32bit DLL that loads a 64bit driver in x64 windows.
