Windows SDK

Windows SDK for X-keys

Windows

This Software Development Kit (SDK) supports all X-keys devices we are currently shipping and offers code examples for Visual Studio C# 2008 Express, Visual Studio C++ 2005 and Visual Studio VB 2010 for Windows; Eclipse for Android.

Note: The information on this page is for Windows-based developers writing applications for Windows or Android operating systems. Options for other developers can be found on the menu to the left.

PIEngineeringSDK.exe (v1064) (15.15 MB) updated 2/25/2019.

Technical Note

Users of the .NET Express versions; C# Express and Visual Basic Express. These versions no longer have the Platform Target selection in the project properties. It is necessary to use a platform target of x86 when using PIEHidDotNet.dll or PIEHid32Net.dll. To do this, open the project's .csproj file (C#) or the .vbproj file (VB) in any text editor and add the line:

<PlatformTarget>x86</PlatformTarget>

.Net Component

The Windows SDK includes two different ways of communicating with the X-keys on Windows systems:

SDK Comparison

The traditional SDK where the developer uses calls to our unmanaged or managed (.NET) DLL to communicate with the device. Samples are included for C++, C#, and VB.NET. All modern X-keys devices are supported.
The new X-keys .NET Components, which include a simplified API that encapsulates much of the functionality of the standard SDK. Once installed in the Visual Studio environment, just drag-and-drop onto your form and support an X-keys device in mere minutes of development time. Samples are included for C# and VB.NET.

More Code Samples

Though the samples in our standard SDK above fit a wide variety of developers' needs, occasionally we've had cause to write special samples. These odd ducks do not fit in with the other samples in our SDK, but you can find them here. If you don't find what you're looking for, please contact us.

Legacy SDKs

In most cases, software developers should use our latest SDK since it supports all devices we are currently offering and works on the most current operating systems. These legacy SDKs offer support for older firmware versions of our X-keys.

Please note: MWII and SE SDKs support devices which have been replaced with newer firmware and have different Product IDs and different SPLAT messages. We encourage you to develop for the latest firmware with the SDK on the first tab.

IMPORTANT NOTE: In order to communicate with our SDK applications, your X–keys USB device must be in Software mode. Our SPLAT Converter Utility (Windows only) will check an X–keys device and set the mode. SplatConverter.exe may also be found on your X–keys SE installation CD in the “\utilities\Memory Resident Mode” directory.

* PIHID Dynamic Load Samples are to be used in conjunction with the individual product SDKs above. They demonstrate how to dynamically load PIEHID.dll, which is necessary to communicate with P.I. Engineering X–keys, RailDriver, and ReDAC devices. Dynamically loading the dll offers an opportunity for the application to do checks for required software or operating systems needed for the application to function correctly. More information is found in the help file.

Notes from the ReadMe file for Legacy SDKs:

The Visual Basic samples were written using Microsoft Visual Basic v6.0 and Microsoft Visual Studio 7.0. Therefore, you must have one of these environments installed in order to open the project. The .exe will run regardless.

The C++ Builder samples were written using Borland C++ Builder 6.0. Therefore, you must have Borland C++ Builder v6 or higher installed in order to open the project. The .exe will run regardless

The Visual C++ sample was written using Microsoft Visual C++ v6.0 and Microsoft Visual Studio 7.0. Therefore, you must have one of these environments installed in order to open the project. The .exe will run regardless.
