vrf simple things ( Modifying buttons in VEE while running)

Barrie,

You sound as if frustration has set in.  I don't know how much I can help
you, but I'll add my two cents worth anyway...

I hate it when I can't do simple things simply.  How do you folks handle
the following?

1) I want a test operator to be able to enter multi-line text comments
while a test is in progress and have the entry added to the data log
file whenever a "done" button is pressed. How do you provide a
reasonable looking multi-line text entry window that doesn't stop the
remainder of the program while waiting for a slow typist?

>Sounds like you need our friend (?) activex here, controlling notepad
perhaps?  I've never done it, but I believe I've seen examples posted here
before.

2) I need to send numerous simple text commands to an instrument with a
short pause between commands (no return data expected) -  exactly what
you would expect alternating "Write text"/"Wait" transactions in a
"To_String" object to do.  Unfortunately, it doesn't seem to work that
way which makes me wonder about the intended purpose of the "wait"
transaction in the first place.  Am I missing something or do you all
use 20 or 30 independent "to_string" objects to accomplish this simple
task?

>I'm not sure what problem you are having here.  In my experience, a wait
transaction works the same as an I/O transaction box and a delay object.
What behaviour are you seeing?

3) I need a push button with an alternating "On" and "Off" caption - it
would be nice to change the color also. Somehow I don't feel this should
require an add-on ActiveX component.

> If you change a Toggle control properties to <custom> you can select an ON
and an OFF icon, which would allow you to create a button with whatever
colour and picture that you want.
