Here's a project for a DLL author to make you loved by millions: Come up with a method to check the Caps Lock state on a remote PC.

No, I don't want the final proggie to run on their computer, I want it to run on mine. I help administer over a thousand desktop PCs and one of the biggest problems we have when it comes to logons is people trying to enter passwords in upper case characters. When I ask "Is your Caps Lock on?" the answer always is "No," spoken in the tone of "(What's a Caps Lock?)"

I want to be smarter than the user. I want to know when they're lying. I want a DLL that'll call the GetKeyState of a remote PC, as in "%a = @keystate(capital[,computername])" or "%a = @keystate(numlock[,computername])." You know what I mean.

So I ask you, fellow programmers, who wants to be a hero? Smile

I'm no programmer, but I doubt that could be done without a program running on the remote PC.

I would not be possible to do without a program running
on the users computer to serve as a client.

Whooooo, Chris. I think that your avatar has gone totally Pulp Fiction! Take
more care when headbanging at your keyboard - maybe that's the way
people's Caps Lock gets stuck so they have to lie to VDSuser about
it Wink

take it anymore? Very Happy

Getting back to the question at hand for a moment, are there any Basic programmers in the forum who are familiar with PEEK and POKE?

I know that using PEEK locally, one can read a specific memory address to check the value of the Caps Lock.

The Basic code for determining the Caps Lock state is:
DEF SEG = 0
X = PEEK(1047) AND 64

If the Caps Lock is off, X will equal 0, otherwise, it will equal 64.

Each bit of location 1047 reflects the status of a keyboard flag. This includes NUM LOCK, SCROLL LOCK, CAPS LOCK, INSert mode, and whether or not the LEFT SHIFT and RIGHT SHIFT keys, the ALT key, or the CTRL (Control) key is currently pressed or not.

Why can't one PEEK a remote PC's memory? 8O

Use Windows XP, it'll warn the user if capslock is turned on while entering
a password in the login screen Wink
