DLL for vb.net

We make a product called "People Tally Counter".

[url removed, login to view]

This product consists of a group of photocells, a digital analogic

converter, a Windows software and a Cloud system for the data management.

When the photocell relay closes, the analogue digital converter converts

the analogue signal into a keyboard function key (F7, F8, F9, F10, F11, F12, F13, F14, F15).

The conversion is performed by an electronic circuit named "Teensy LC".

[url removed, login to view]

Whenever the Teensy device raises a key event (F7, F8...), our VB.NET <http://vb.net/> software memorizes a timestamp and then sends the data to our cloud system.

Since our software works in backgound mode, the PC is free to be used for other functions.

So far we have used our own library to perform the keyboard hook, but this library continues to give us numerous problems and it's not reliable.

So we need to find out an alternative to our library.

We need a DLL to be used in VB.NET <http://vb.net/> and/or C# programs.

This DLL must read the keyboard events even if the application is not in focus.

The events (for the key F7, F8, F9, F10, F11, F12, F13, F14, F15) we need are the following:

- Last Key Down

- Last Key Up

- Depress Time

- Lag Time the time between key pressed

Are you able to make this DLL and how much does it cost?

Thanks you

Best Regards
