Driving the LCD Smartie to the edge

(and it's functions) I think I've discovered a bug

in the plugin.

I'm running two (and sometimes more) instances of LCD Smartie with different configuration files (config.ini) to drive more than one displays from my computer!
The plugin is working great with the first instance of LCD Smartie but when I try to assign a new hotkey to the second, I get the following message when I start the second instance: "hotkey plugin" "ERROR: RegisterHotKey() failed for hotkey #1"

Clicking OK allows me to run Smartie without plugin...

Please check it out (it's not a major bug but I think You can override it!)

Wow two displays and two smarties. Your dedicated limbo, I'll give you that.

Oh, I never thought about running more than one instance of LCD Smartie.

Hotkey plugin can be used for that but it is a bit complicated. Read on.

problem
The most common reason for RegisterHotkey() to fail is that the specific hotkey (modifier/virtualkey combination) is already registered as a global hotkey.

solution
If you run two instances of LCD Smartie then you must make sure that they use different hotkeys. It is not possible to use the same hotkeys in both instances at the same time.

Hotkey plugin reads the key codes from the file "hotkey.ini". This file must be inside the "plugins" folder, which is located in the folder where "LCDSmartie.exe" resides. So, in order to have two different copies of "hotkey.ini" you have to have two different copies of the entire LCD Smartie folder (including "plugins" sub-folder).

notes
I see that this is inconvinient but this is the way it currently works. Maybe I should think about a better solution...

On the other hand, the "key plugin" by akx does not have these restrictions. It doesn't register any hotkeys in Windows, instead it polls the keyboard directly. Therefore, two instances of LCD Smartie can use the same keys without any problems.

I'm trying to use this hotkey dll to turn my backlight on and off. I have successfully installed the plugin and the hotkey ctrl-F10 turns the backlight on and off in the LCD smartie window, but the backlight on my physical LCD screen stays on. Does that mean I need to learn more about electronics or is there some separate function to turn the backlight on and off that I need to use?

Thanks

Rob

Probably you are using parallel connection to your LCD... YOU have to use the cicruit that drives the backlight through a transistor.

We are indeed using a circuit where there is a transistor, I think it drives the backlight but I'm not totally certain of that (not a huge electronics person) - we used this schematic http://lcdsmartie.sourceforge.net/LCDconnect.jpg

Thanks but it turned out I had the base and collector switched on the transistor, so my bad. BTW if you do that it doesn't work
