text box to string

[mgaudio]

Hi!

I think my question might be answered by the basic label manual. I can't download it anymore by going to my account? it shows I have 2 downloads left.

anyway, my question is pretty basic. I want to have a text field that can have text entered into it....and it will be stored in a string (say, ST9:0 ) on my micrologix 1100.

how would I go about doing this?


Also, I saw a really great little video demo on here where a gent had integrated a password into his program. How would I start with doing this.

I really appreciate your time, and I love this program so far......I just wish there was a beginners manual for it!

There is a new feature in the latest release that will help you do this.

1) Add a BasicLabel
2) Set PLCAddressValue to ST9:0
3) Set PLCAddressKeypad to ST9:0
4) Set KeypadAlphanumeric to True
5) Run the application and click on the BasicLabel

When I do this I get the error "object reference not set to an instance of an object"

[Archie]

Does it give you any details such as the program file and line number?

The error is being generated when I run the program......I have not done any programming since my visual basic class in college, so this is a bit beyond me.

When I close out of the running program demo/debug I get this in the visual studio console output:

Does the label change to an error message before or after you click it?

I don't have a PLC available to test it right now. I have only been able to test on the simulator, so sorry for all the questions.

[mgaudio]

Its no problem Archie, I appreciate your development and replies. A lot.

the error occurs before I click on the label, then it goes away. If I click on the label the keypad comes up and if I enter something into it and click the "enter" button it will show me the error again and then the error will disappear until I try it again (click on it and try entering something).

So...before And After a click.

A programmer in our office isn't very familiar with MS products, but said that "you're performing a click action on a form element" and that was the issue.....but it does come up before any click interaction.

Try to change PLCAddressValue to something else like N7:0

I think the problem is in the driver trying to read a string value

[mgaudio]

that appears to be it.
Is there a modification I can make to the driver so that it can communicate string values?
