An app which prevents merchant service logout

[Rod Hutton]

Hi,

A We user who is running a business is looking for a way of avoiding 
being logged out by one of his merchant service providers.  It seems 
that if there is no keyboard activity for 20 minutes or so, he is logged 
out, which is inconvenient for him.  I suggested that I could write an 
app for him, but I was wondering what would be the safest approach to 
take in creating the routine to send a single character, what character 
would be best, and how to implement it.  Obviously, there would be a 
timer, and I can write this with no problem.  The ideas I have in mind are:

Have a timer running, and execute the Keyboard.WaitForAllKeysUp() 
command every minute to ensure that the monitored time begins only after 
this is checked, and then the keystroke is sent after, say, 15 
iterations, that is, there has been no keyboard activity for 15 minutes, 
in which case the keystroke is sent.

I want to send only the Control key to avoid sending something more 
complex which might cause problems.

Well, that's about all I can think of reight now, and I certainly 
appreciate your ideas, including specific lines of code. smile

Much thanks,

Rod
