Plunging into xbasic, finally!

[RobPolley]

I'm working on a student quiz application.

I have 3 fields on a grid:

1. The correct answer (it will be hidden).
2. The student's answer.
3. The status of the answer.

The grid will show only 1 row at a time.

If the student's answer is correct, I want the status to show "correct". If it's incorrect, I want the status to say, "not quite."

I'm thinking this is an "after validate" event. I'd really appreciate it if someone would point me in the right direction. I do not have to store the answer, only indicate whether it's status is "correct" or "not quite."

Many thanks!

Rob,

There are so many ways to approach this.

I would probably use the Validate event, because by putting your xbasic there, you can more easily get the appropriate messages to display on the SAME page.

Gary,

I appreciate your help. May I impose upon you for the direction in which I should go regarding the code? Is this an "if" event?

Thank you.

Rob,

More than happy to help in any way I can.

Actually, this is a grid, not a dialog, so no Validate event - You can use the CanUpdateRecord event, with code something like:

if DataSubmitted.thefield="the wrong answer" then
Result.Cancel = .t.
Result.ErrorHTML = "Wrong answer - try again!"
end if

Rob,

Something I found of interest in doing a test with TEXT answers was using SoundEX

eg
vQuestion = "Who made this Test ?"
vAnswer = "RobPoley"

if (Soundex(RobPolley) = Soundex(vAnswer) Then
---
---
---

This provides some leeway for users

Colin,

That may solve another issue; thank you!

I'm getting the validation to work; I appreciate your help.

Is it possible to alter the format that the validation box assumes?

For Example, the heading is "Validation Errors"

I'd rather not have any heading.

It also indicates the row number, which I'd rather not have.

Finally, I'd like to change the font size.

Is it possible to do any of this?

(I have been able to move the small section of the grid component that contains the validation error message.)

Thank you!

Re: Plunging into xbasic, finally!

On my test system, I now have a "Can update record" event working to show that an answer is incorrect.

I have not been able to show that it's correct. I suppose that "no response" could equal a correct answer, but I was hoping to have responses for both incorrect and correct answers.

For some reason, I think that Result.ErrorHTM will display only if result.cancel=.t.

I'd like to display a message if result.cancel=.f.

Is this possible?

Thank you.

Re: Plunging into xbasic, finally!

Rob,

To have more control, like what you want to do with the error message, you should use a dialog instead of a grid.

However, assuming you will stick with a grid, the result.cancel=.t. is not referring to whether the answer was right or wrong. It refers to whether to trigger an error message or not. If it is .t., then the 'cancel' tells a5 not to commit the record, and to display an 'error' message. in your case, you want that to be .t. in either case, something like:

if answer is correct
Result.Cancel = .t.
Result.ErrorHTML = "Correct answer - good job!"
else
Result.Cancel = .t.
Result.ErrorHTML = "Incorrect answer - try again!"
end if

Gary,

That was my hunch, but I must have written the code incorrectly. I'll try again.

Thanks, also, for the tip on dialogs. I have used them only to create a "print" button. I guess I'll take the plunge there, too.

Thank you for your help!
