Disable the windows key?

[ScooterInMN]

Task manager can easily be disabled by changing a registry value.  I also need to lock out the Windows keys.  Since NI claims that LabVIEW is Part 11 compliant, I would have assumed that this function would be standard but I digress.

I have found the registry value but for some reason, the value does not get written into the registry correctly:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout]
"Scancode Map"=hex:00,00,00,00,00,00,00,00,03,00,00,00,00,00,5B,E0,00,00,5C,E0,00,00,00,00

I have also tried to write the binary value (0000 0000 0000 0000 0300 0000 0000 5BE0 0000 5CE0 0000 0000) as well with no luck.

Any ideas??

Thanks all!

I think you have to restart windows before the change in keybord settings take place

The problem isn't the restarting of the PC.  The problem is writing the correct value to the registry.  I already have in other pieces of my code to reboot after any security change.  Check out the VI I attached.

This web site has some info

It is also a lt of code examples out there for C++ and VB. Perhaps a frind of yours may write a simple dll. But I can not help you out. I have not written C code for 10 years now

This is the article that I followed.  The problem is that I can't get LabVIEW to correctly write the value to the registry.

What happens when you try? Is the key not written? Written but not correct? Error messages?

Thanks to you I have no windows key (until I reboot ). Change the setting for the string const. Then you can write pure hex values. Go to the msdn web site and cut and paste the values .Worked for me. Then I came to work today I had no windows key
