 Send Ctrl-Z to Com Port using MSComm Hi all,
I wish to send the Ctrl-Z and Ctrl-E keys to the Comm port. Something
like this
MSComm1.output = "^Z"
or
MSComm1.output = "{CTRL}Z"
But I can't get any of them working. Anybody got any ideas?
Thanks for the help,
Jim
P.S. What is the best way of storing passwords? If I write them
to a file as text, anybody and everyone will be able to read
them. I want to be able to read them back as well.
Any ideas?

Ctrl-Z is chr$(26) and Ctrl-E is chr$(5). Try this: MSComm1.output = chr$(26)
or
MSComm1.output = chr$(5)
See your ASCII chart for other control code values.

Chr$(13) is a Ctrl-M (a carriage return.) Take it from an old bit-basher. --

[snip] No, Chr$(13) is control-M. ^Z is Chr$(26), ^E is Chr$(5).
In general, you can pull up the help topic for the ANSI character
set, find the letter you want the control code for in the third
or fourth column, and locate the number in the far left column on
the same row. Alternatively, do this in a Debug window:
? Asc("E") And 31, Asc("Z") And 31
5 26

The best way would be to encrypt them before writing them out to a file. I don't have an encryption routine that I can give you, but you will have to choose one based on the security level you want. There are a lot of routines available. The simplest would probably be to choose some string of characters that appears in your code and use it as a key to encrypt and decrypt the pass words. That isn't very secure, but it would at least keep somebody from getting it by just looking at your INI file with a text editor. Other wise check and see if you can find a shareware encryption routine. Good luck,

For the password solution: I used an access database which I protected with Tools/Set Database Password.
In this database I have a table which stores the passwords.
In VB used Opendatabase("DatabaseName",False,False,";PWD=PassWord") to open
the database using the password set in Access. This way the only one able to
see the passwords is the one who developes the code. (because he knows the
password)

You also need to make sure that the database isn't owned by the Admin user inside Access, because if anyone else who has Access and doesn't use any type of user login system opens Access they are "logged in" as Admin - thus giving them permissions to open the database without knowing the password. The easiest way I've found to do that is to create your database as the Admin user, then log in as someone else, create a new database as that user and then transfer all tables, queries, etc. to the new database. Kinda confusing, but it works.

Try this: For Control Z: mscomm1.output = chr(26)
For Control E: mscomm1.output = chr(5)
26 is the ascii code for Ctr-Z, 5 is the ascii code for Ctr-E. Some
programming book (especially those relating to modem programming) contain a
table of the ascii code of all the control code. Try to get hold of one copy
of it.
Regards.
