CE Remote Display Application

The Remote Display allows to operate the target device's Win CE desktop from a Windows PC. It requires a USB ActiveSync connection.

Download X86 remote display application (over ActiveSync connection)

Usage

1. Extract the zip file on your PC.

2. Wait for the ActiveSync connection to be ready.

3. Start ASRDisp.exe.

WEC7 DHHalLib (function library)

The DHHalLib provides hardware related functions for Windows Embedded CE 6 and Windows Embedded Compact 7. All the functionality is available from the user mode.
