Make batch react to buttons

[Sky Ninja]

I need to make a batch file react to button pushes, but most people who get my file won't have the choice command available. I don't want them to have to go through installing it, so is there a way other than choice /c:?

[Carbon Dudeoxide]

Nope, you cannot make a button like on the Internet.

[Sky Ninja]

 
What I meant is a button on the keyboard. I need an alternative to choice /c:*whatever*.
I know you can't do things such as clickable buttons. That's only available through .com or .exe. Edit.com for example.

[Carbon Dudeoxide]

Oh sorry, do you mean Keyboard presses? 

[Sky Ninja]

Yep.

[Carbon Dudeoxide]

I think there might be a way, but you will have to wait for our Batch Gurus to assist.

Hi

Immediately below the "Logout" button you will find a Search box

If you search for "choice" you get more hits than I care to list.

The first Hit takes you to "http://www.computerhope.com/choicehl.htm"
This links to "http://www.computerhope.com/sethlp.htm", which should give more than enough help.

If you want further help, or want to see examples of how to do it, then Hit 2, or any one of more than 50 other hits, should do the job.

Regards
Alan

Just getting all of the key numbers, watch this space.

The pause would help

I guess if you run the batch by double clicking it in Windows Explorer, yes, it would help by stopping the command window abruptly closing. I am used to trialling new batch files by having a command window open and typing the batch name at the prompt, to avoid exactly that problem.

Also, it strikes me that it might be handy to know the actual character of the key which has been pressed, so I whipped up a simple vbscript to return that

Just as I was trying to do it the hard way:

[Dias de verano]

Yes, my first thought was to do it the long way, of testing for every errorlevel possible, then I remembered how many keys there are on a keyboard, and I thought that nobody will want to add several hundred lines to their batch file.

This is just every letter in case anybody wants it:

1. Your code only works for lowercase letters of the alphabet 'a' to 'z'.

2. But you show uppercase letters to the user. ASCII 97 is 'a' not 'A'. The keypress program gives a different code if a key is shifted or if Caps Lock is operative.

3. By using this format

if test (
   do this
)

Rather than this

if test do this

You are adding 2 unnecessary lines for each simple IF test
