trying to think modular

[mikeycorn]

I'm working on my first program in VB6, it's a program that will automatically pull up random questions from a text file full of multiple choice questions for the A+ quiz and test me on the material.

So far, I've got a routine to load all the questions into arrays (thanks to the help of Andrew Empson) and I put this routine into the Form_Load. I then have the code that randomly picks and displays the question and multiple choice answers and when you hit the "submit answer" command button, the program can tell if check boxes you've selected for the multiple choice are right or wrong.

And this is where I'm stuck. I'm going to turn the "submit answer" command button into a "next question" command button, but I don't know how to get back to the Form_Load from there. Obviously, I also don't want to reload the text file of questions into the arrays each time I hit the Form_Load. Where the heck is the GOTO statement in this modular world?

I think that the best way to make this is to call a subroutine that ask the question.

if your button name for "next question" is BtnNextQuestion, the code like this :

sub Form_Load ()
LoadingQuestion
AskingQuestion
end sub

sub BtnNextQuestion_Click
AskingQuestion
end sub

Sub LoadingQuestion()
' put here the code to load all the questions
end sub

Sub AskingQuestion()
' put here the code to ask the next question
end sub

Hi MikeyCorn

Kwell's pretty much summed it up, but it may be a little hard to understand if you're fresh from Qbasic.

Here's what you need to do...

Have a button called Command1 on your form along with the check boxes.

Add this to the end of your Form_Load event

Call LoadQuestion
Command1.Caption="Submit Answer"

In the Command1_Click event you could do something like

If Command1.Caption="Submit Answer" Then
  If CheckAnswer(QuestionNumber)=True Then
    Msgbox("Correct!")
  Else
    Msgbox ("Incorrect.")
  End If
  Command1.Caption="Next Question"
Else
  Call LoadQuestion
  Command1.Caption="Submit Answer"
End If

Then make a new Function called 'CheckAnswer' by typing this in at the beginning of your code (in General)

Function CheckAnswer(ByVal QuestionNumber) as Boolean
  'Put the code here to check if the answer to Question(QuestionNumber) is correct
  If TheAnswer=True Then  
    CheckAnswer=True
  Else
    CheckAnswer=False
  End If
End Function

Finally, make a new function called 'LoadQuestion' like this, also typing it in the General section of your form.

Sub LoadQuestion()
  'Load a new question and change the variable QuestionNumber to its index
  'Clear all of the check boxes and things
End Sub

EXCELLENT! Thank you both for taking the time to help . . . I've got alot to chew on now and it will probably be a while before I'm back. :-)

When this project's done, it'll be fun sharing it with y'all.
