Visual basic help

[jesus]

I'm trying to get the output to be displayed in a picture box, but it just doesn't want to work. I can't see where my mistake is.

This is my code:

Private Sub cmdCalculate_Click()
Call ChooseMath
Call DisplayInfo
End Sub

Sub ChooseMath()
If optAdd = True Then
FirstNumber = Val(txtFirstNumber)
Operation = "Add"
SecondNumber = Val(txtSecondNumber)
Result = Val(txtFirstNumber) + Val(txtSecondNumber)
End If

If optSubtract = True Then
FirstNumber = Val(txtFirstNumber)
Operation = "Subtract"
SecondNumber = Val(txtSecondNumber)
Result = Val(txtFirstNumber) - Val(txtSecondNumber)
End If

If optMultiply = True Then
FirstNumber = Val(txtFirstNumber)
Operation = "Multiply"
SecondNumber = Val(txtSecondNumber)
Result = Val(txtFirstNumber) * Val(txtSecondNumber)
End If

If optDivide = True Then
FirstNumber = Val(txtFirstNumber)
Operation = "Divide"
SecondNumber = Val(txtSecondNumber)
Result = Val(txtFirstNumber) / Val(txtSecondNumber)
End If

If optBritishColumbia = True Then
FirstNumber = Val(txtFirstNumber)
Operation = Exponent
SecondNumber = Val(txtSecondNumber)
Result = Val(txtFirstNumber) ^ Val(txtSecondNumber)
End If
End Sub

Sub DisplayInfo()
picOutput.Print FirstNumber, Operation, SecondNumber, Result
End Sub

Private Sub cmdExit_Click()
End
End Sub

What am I doing wrong?

Re: Visual basic help

You haven't declared any variables?

Re: Visual basic help

What do you mean?

Re: Visual basic help

You have to tell VB what your variables are and what data type they are at the start of the program.
Eg:

dim optAdd as boolean

Are you just starting out with VB?

Re: Visual basic help

I've been trying to figure it out for like half an hour now lol

I used this

Dim FirstNumber, Operation, SecondNumber, Result As Single

and now it works!

Thanks a lot

VB sucks, go C# :)

It doesn't suck it's only purpose is rapid development which it does exceptionally well. But if you want to play with the big boys and girls you will have to go C#, C++, Python, Perl, and if you want to have a little extra work do Java.:thumbsup:

C# is real good for rapid development too!

Re: Visual basic help

I can't do C++ because this is a class at school and we're required to use visual basic
