It is binary compatible with Smartphones, Pocket PCs and Windows desktops (with .NET Compact Framework or .NET Framework).

I write this mainly because other VNC viewers on Pocket PC do not do full screen and screen rotation.

Features:
- Of course, basic VNC viewer functionalities.
- Full screen mode.
- Client-side scaling.
- Server-side scaling and single window mode.
- Screen rotation.
- Session history.
- Hi-Res support for VGA Pocket PC and QVGA Smartphones.
- Listen mode.
- Etc.

Installation:
Just copy the exe to a directory on your device and execute from there.

Update Description:
v1.0.1.17:
- Implemented listen mode.
- Added an option for Smartphone users to turn off mouse acceleration.
- Added an option for Smartphone users to choose the mouse speed after turning off mouse acceleration.
- For Smartphones with a QWERTY keyboard, now the lower case "p" and "q" keys should work as expected.
- More keys were added to the Keys menu (Esc, Tab, and Fn keys).
- Avoided an exception for some .NET CF devices with no connection manager.

v1.0.1.16:
- Server-side scaling and single window mode implemented.
- On a PPC or a Smartphone, now the viewer calls into the connection manager to initiate a network connection (e.g. GPRS) before connecting to the server. From now on the viewer is not P/Invoke-free anymore.
- Added an icon.
- Added an option for users to choose whether to update the screen ASAP or in a batch.
- Added a sample build script.
- Fixed a bug that would hang the viewer if the connection is terminated unexpectedly.

v1.0.1.10:
- Client-side scaling implemented.
- Fixed a problem with Smartphone key input mode which prevents the viewer from going back to mouse mode after exiting extended input mode.
- For Smartphones, the back soft key is now backspace even not in key input mode.
- Improved the code for painting.
- Made adjustments to thread priority to provide a more responsive UI.
- Added "Shift Down" and "Shift Up" to the "Keys" menu.
- For Smartphones, added an option to send the mouse location to the server when the cursor is idle.
- Fixed a bug on Smartphones that would cause the right mouse button to not properly function after exiting full screen mode.

Realmente excelente, permite rotar y conectarse a un servidor VNC (UltraVNC en mi caso). Gracias por compartir vuestro desarrollo.

WOW! WOW! WOW! Works like a dream. Perfect. Right click not a problem on pocketPC. This is so easy to use and operates flawlessly that I would gladly pay for this software. Where do I send the check? :-)

This VNC viewer rocks! It works with VNC server version 4.X as well. Thanks for sharing this excellent app.

Using XP as "the server" this actually works better than mstsc in as much as the server can be logged on for access by the remote PDA. So for arguments sake when I have my navigation package running on my laptop which is in a locker on my yacht I can be sitting on the deck with the PDA accessing it. The only thing I had trouble with was trying to force a "right click" to bring up menus, I seemed to jag it occasionally but not consistently.
