Abeg O,help Me With Dis VB.NET Code by Lakulos(m): 9:17pm On Oct 13, 2012
I trying to write a program on a simple calculator using visual studio 2008,i want the user to be able to enter values in 2 textboxes and submit the result to a third textbox,the problem am encountering is that the program is not bringing out error and it is not also it is not calculating anything. This is my code.

Dim num1 as integer
Dim num2 as integer
Dim ans as integer
num1=val(textbox1.text)
num2=val(textbox2.text)
ans=val(textbox3.text)
ans=num1+num2.
Thanks.

I'm a bit rusty with VB but from what I can see, everything works just that you're not showing the answer in textBox3. So perhaps you might want to do something like this:
textBox3.Text = ans

^^^^Your code should work, but....

0-Dim num1 as integer
1-Dim num2 as integer
2-Dim ans as integer
3-num1=val(textbox1.text)
4-num2=val(textbox2.text)
5-ans=val(textbox3.text)
6-ans=num1+num2.
Thanks.


@line5: what's this supposed to be doing? assigning unknown value of Textbox to Your result! code can't work!
@line6: correct! but where are you displaying this result? certainly not Textbox3.

anyway, change line5 to: ans = num1+num2, then line6 to: Textbox3.Text = ans. should work .

also,

        Dim num1 As Integer = Integer.Parse(TxtNum1.Text)
        Dim num2 As Integer = Integer.Parse(TxtNum2.Text)
        TxtResult.Text = num1 + num2


Advice: If you're a newbie, or even a seasoned programmer for that matter; always get the logic of your intended program done on a paper before rushing to your editor....It reduces Your brain processing time.

I think Mkwayisi has answered your question but just want to chip in a little.
The variable 'ans' has your value in memory but you have not asked your application to display the result.
You can do this a variety of ways including mkwayisi's suggestion (textbox3.text = ans). e.g

textbox3.text = val(textbox1.text) + val(textbox2.text) just to miniaturize your code. But this is sure NOT the best way to do it.
