[VB6] Preventing Division By Zero

[Blufner]

I had a thread up before and someone answered me but it was deleted so when I came back for reference it wasn't there. Can someone tell me what had to be done? I remember a pseudo code or something.

Anyway the problem was:

If I run my program and click the calculate command without entering any integers (therefore I am dividing by zero) my program Breaks.

What is the code to prevent division my zero?

 

[Daevius]

Make a function which takes 2 numbers. Check the second number and see if it's zero. If so, throw an exception, if not, divide and return the result.

 

[Blufner]

I don't get it @_@ Look at my other post... It has the code.


I don't even know how to write a function....

 

[Donkjam]

huh so you wanting to Divide by Zero? the code for a calculator is like

text3.text = val(text1.text) / val(text2.text)

is that what u mean??

 

[Daney]

Check whether numOne or numTwo are 0 and if either/both are, just throw an error.

if(numOne == "0" || numTwo == "0")
{
cout << "Cannot divide by zero.";
} else {
//Contiune to show answer.
}

Just add that code into the section where it checks for division.

 

[GriffinHeart]

0 divided by something is valid so that won't work, just check if the divisor is 0.

 

[Monsta.]

public function checkforzero(num1 as string, num2 as string)
if num1 = "0" or num2 = "0" then
msgbox "you can't use 0 - Monsta.", vbexclamation + vbokonly
else
form1.lblanswer.caption = val(num1) / val(num2)
end if
end function

Don't know, just made it up, try it ^^
